Cancer Treatment 101: A Primer for Non-Oncologists
The remaining 700,000 or so often proceed to chemotherapy either immediately or upon cancer recurrence, spread, or newly recognized metastases. “Cures” after that point are rare.
I’m speaking in generalities, understanding that each cancer and each patient is unique.
Chemotherapy
Chemotherapy alone can cure a small number of cancer types. When added to radiation or surgery, chemotherapy can help to cure a wider range of cancer types. As an add-on, chemotherapy can extend the length and quality of life for many patients with cancer. Since chemotherapy is by definition “toxic,” it can also shorten the duration or harm the quality of life and provide false hope. The Table summarizes what chemotherapy can and cannot achieve in selected cancer types.
Careful, compassionate communication between patient and physician is key. Goals and expectations must be clearly understood.
Organized chemotherapeutic efforts are further categorized as first line, second line, and third line.
First-line treatment. The initial round of recommended chemotherapy for a specific cancer. It is typically considered the most effective treatment for that type and stage of cancer on the basis of current research and clinical trials.
Second-line treatment. This is the treatment used if the first-line chemotherapy doesn’t work as desired. Reasons to switch to second-line chemo include:
- Lack of response (the tumor failed to shrink).
- Progression (the cancer may have grown or spread further).
- Adverse side effects were too severe to continue.
The drugs used in second-line chemo will typically be different from those used in first line, sometimes because cancer cells can develop resistance to chemotherapy drugs over time. Moreover, the goal of second-line chemo may differ from that of first-line therapy. Rather than chiefly aiming for a cure, second-line treatment might focus on slowing cancer growth, managing symptoms, or improving quality of life. Unfortunately, not every type of cancer has a readily available second-line option.
Third-line treatment. Third-line options come into play when both the initial course of chemo (first line) and the subsequent treatment (second line) have failed to achieve remission or control the cancer’s spread. Owing to the progressive nature of advanced cancers, patients might not be eligible or healthy enough for third-line therapy. Depending on cancer type, the patient’s general health, and response to previous treatments, third-line options could include:
- New or different chemotherapy drugs compared with prior lines.
- Surgery to debulk the tumor.
- Radiation for symptom control.
- Targeted therapy: drugs designed to target specific vulnerabilities in cancer cells.
- Immunotherapy: agents that help the body’s immune system fight cancer cells.
- Clinical trials testing new or investigational treatments, which may be applicable at any time, depending on the questions being addressed.
The goals of third-line therapy may shift from aiming for a cure to managing symptoms, improving quality of life, and potentially slowing cancer growth. The decision to pursue third-line therapy involves careful consideration by the doctor and patient, weighing the potential benefits and risks of treatment considering the individual’s overall health and specific situation.
It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.
Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
Interventions to Consider Earlier
In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:
- Molecular testing.
- Palliation.
- Clinical trials.
- Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.
I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.
Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:
- Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
- Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
- Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.
Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.
Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.
Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.
Specific situations where discussing palliative care might be appropriate are:
- Soon after a cancer diagnosis.
- If the patient experiences significant side effects from cancer treatment.
- When considering different treatment options, palliative care can complement those treatments.
- In advanced stages of cancer, to focus on comfort and quality of life.
Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.
In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.
Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.
These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

Multiple Myeloma: New Treatments Aid Patient Subgroups
“The introduction of treatments such as elranatamab (Elrexfio) is allowing patients with multiple myeloma, which is still incurable for now, to have different options and achieve long periods of remission, thus improving their survival,” she added. “This therapeutic innovation is highly effective and well tolerated in patients with relapse or refractory multiple myeloma.” The overall response rate is “up to 61%, early, deep, and long-lasting.”
In an interview with El Médico Interactivo, Dr. Mateos explained the new approaches to multiple myeloma. She highlighted the effectiveness of new treatments and reviewed the latest data on this disease, which were presented at the recent European Hematology Association Congress.
What is the incidence rate of multiple myeloma in the Spanish population?
Multiple myeloma has an incidence of approximately 4-5 new cases per 100,000 inhabitants per year. This means that around 3000 new cases are diagnosed each year in Spain. As with most tumors, multiple myeloma is generally slightly more common in males than females. It is the third most frequent hematologic cancer in men (1757 new cases) and women (1325 new cases), behind lymphoma and leukemias.
At what age is it most often diagnosed?
It affects older people, with recent reports indicating around 68-69 years as the median age. Although more young people are being diagnosed with multiple myeloma, analyses of how this hematologic cancer affects the general population show that it generally impacts patients over age 65 years.
What is the typical survival prognosis?
Thanks to research and therapeutic innovation, the prognosis has changed significantly over the past 20-25 years. Today, if a patient with multiple myeloma receives a diagnosis and does not exhibit poor prognostic characteristics (and this description fits approximately 70%-80% of patients with multiple myeloma), it is realistic to expect a survival exceeding 10 years. A few years ago, this outcome was unimaginable, but a significant amount of therapeutic innovation has made it possible. That’s why I emphasize that it is realistic to provide these data with such a positive outlook.
Is multiple myeloma a refractory type of cancer?
It was a refractory type of cancer. Twenty years ago, there were no treatment options, and therefore survival was around 2-3 years, because treatment mainly consisted of using alkylating agents and corticosteroids. This is what made it refractory.
With the emergence of new therapeutic innovations, patients have been responding better and their responses are lasting longer. Although there is still a group of patients, about 10%-15%, with a poor prognosis and refractory disease, those with standard risk are responding better to different therapies.
Although most patients will eventually exhaust the treatments, which until now were primarily triple-drug regimens (such as proteasome inhibitors, immunomodulators, and antiCD38 antibodies), the introduction of new therapies is extending the duration of responses.
Is the risk for relapse high?
It is very high, in the sense that almost all patients with multiple myeloma eventually relapse. However, we hope that there soon will be some patients who do not relapse.
What are the typical pathologic manifestations of this cancer? Does it affect everyone equally, or in specific ways in each person?
In multiple myeloma, we often say there are multiple myelomas. Clinically, the disease presents in most patients, around 80%, with two clinical manifestations: anemia and bone lesions. Less frequently, patients may also have kidney failure, hypercalcemia, and a higher tendency toward infection. Behind this rather common symptomatology, from a molecular and genetic perspective, each myeloma is practically unique, adding complexity to its treatment. Therefore, ultimately, myelomas end up being refractory.
Elranatamab is a new therapeutic tool. For which patients is it recommended?
It is a bispecific monoclonal antibody that corresponds to the new monotherapy strategies we have for treating patients with multiple myeloma. On the one hand, it targets damaged plasma cells, which are the patient’s tumor cells, and on the other, it binds the patient’s T cells and redirects them to the tumor niche. When this happens, the T cell activates and destroys the tumor cell.
This medication has been approved for patients with relapsed myeloma who have received traditional drugs for their treatment. We know well that patients who have already received proteasome inhibitors, immunomodulators, and anti-CD38 antibodies typically need something new after treatment. Before, there were no other options, and we would reuse what had been previously used. Now we have elranatamab, a bispecific monoclonal antibody targeting a new receptor that has shown significant responses as monotherapy.
More than 60% of patients respond, and more than 30% achieve complete remission. The key is the response duration and progression-free survival of almost a year and a half. This is the longest progression-free survival we have seen to date in previous lines. Therefore, it fills the needs we had for these relapsed or refractory myeloma patients.
What advantages does this new treatment offer?
It represents a therapeutic innovation because, as mentioned, it achieves a response in more than 60% of patients, and around 35% achieve complete remission. The median response duration has not been reached yet. Progression-free survival is 17.2 months, almost a year and a half, and overall survival is almost two years.
Furthermore, it is administered as subcutaneous monotherapy weekly for the first six cycles and then every 15 days. It has a good safety profile, although some adverse events are known, so we have strategies to combat or mitigate them, making the treatment generally well tolerated.
What side effects are being observed?
They are manageable. When the drug is first administered, patients may experience what we call a cytokine release syndrome, which is a result of the treatment’s mechanism. However, we can predict very well when it occurs, usually 2 days after the first doses, and we have strategies to mitigate it.
The second most common adverse event we need to be cautious about is infection. Nowadays, before starting treatment, patients update their vaccination schedule, receive antiviral prophylaxis, and receive prophylaxis against certain germs, resulting in reduced infections. However, infections are probably the adverse events we need to be most careful about when treating the patient.
We must ensure that prophylaxis is performed, and if fever occurs and an infection is suspected, cultures and all kinds of studies must be done to identify and treat it properly.
How does elranatamab change the treatment of an incurable disease? Does it bring us closer to a cure or to making multiple myeloma a manageable chronic disease?
With the already approved elranatamab, the most important aspect is that it adds another treatment option for patients with myeloma. With the progression-free survival data I indicated, life expectancy is increased, with a good quality of life and acceptable safety.
Obviously, elranatamab is still under study and development, even in early lines, including in patients with newly diagnosed myeloma. When we are choosing first-line therapy, we select the best patients by combining traditional drugs with these new immunotherapies, such as elranatamab, it is likely that we are much closer to offering a cure to specific subgroups.
Although it won’t happen in all cases, I believe it will be applicable to a significant subgroup of patients, making chronicity of the disease a reality we are already approaching. Each day, we encounter more patients receiving different lines of treatment and ultimately meeting their life expectancy with myeloma. Even though some may die, it is often due to causes not related to myeloma. This is the most important contribution of these innovations, such as elranatamab.

The median response duration has not been reached yet. Progression-free survival is 17.2 months, almost a year and a half, and overall survival is almost two years.
Furthermore, it is administered as subcutaneous monotherapy weekly for the first six cycles and then every 15 days. It has a good safety profile, although some adverse events are known, so we have strategies to combat or mitigate them, making the treatment generally well tolerated.
What side effects are being observed?
They are manageable. When the drug is first administered, patients may experience what we call a cytokine release syndrome, which is a result of the treatment’s mechanism. However, we can predict very well when it occurs, usually 2 days after the first doses, and we have strategies to mitigate it.
The second most common adverse event we need to be cautious about is infection. Nowadays, before starting treatment, patients update their vaccination schedule, receive antiviral prophylaxis, and receive prophylaxis against certain germs, resulting in reduced infections. However, infections are probably the adverse events we need to be most careful about when treating the patient.
We must ensure that prophylaxis is performed, and if fever occurs and an infection is suspected, cultures and all kinds of studies must be done to identify and treat it properly.
How does elranatamab change the treatment of an incurable disease? Does it bring us closer to a cure or to making multiple myeloma a manageable chronic disease?
With the already approved elranatamab, the most important aspect is that it adds another treatment option for patients with myeloma. With the progression-free survival data I indicated, life expectancy is increased, with a good quality of life and acceptable safety.
Obviously, elranatamab is still under study and development, even in early lines, including in patients with newly diagnosed myeloma. When we are choosing first-line therapy, we select the best patients by combining traditional drugs with these new immunotherapies, such as elranatamab, it is likely that we are much closer to offering a cure to specific subgroups.
Although it won’t happen in all cases, I believe it will be applicable to a significant subgroup of patients, making chronicity of the disease a reality we are already approaching. Each day, we encounter more patients receiving different lines of treatment and ultimately meeting their life expectancy with myeloma. Even though some may die, it is often due to causes not related to myeloma. This is the most important contribution of these innovations, such as elranatamab.

“The introduction of treatments such as elranatamab (Elrexfio) is allowing patients with multiple myeloma, which is still incurable for now, to have different options and achieve long periods of remission, thus improving their survival,” she added. “This therapeutic innovation is highly effective and well tolerated in patients with relapse or refractory multiple myeloma.” The overall response rate is “up to 61%, early, deep, and long-lasting.”
In an interview with El Médico Interactivo, Dr. Mateos explained the new approaches to multiple myeloma. She highlighted the effectiveness of new treatments and reviewed the latest data on this disease, which were presented at the recent European Hematology Association Congress.
What is the incidence rate of multiple myeloma in the Spanish population?
Multiple myeloma has an incidence of approximately 4-5 new cases per 100,000 inhabitants per year. This means that around 3000 new cases are diagnosed each year in Spain. As with most tumors, multiple myeloma is generally slightly more common in males than females. It is the third most frequent hematologic cancer in men (1757 new cases) and women (1325 new cases), behind lymphoma and leukemias.
At what age is it most often diagnosed?
It affects older people, with recent reports indicating around 68-69 years as the median age. Although more young people are being diagnosed with multiple myeloma, analyses of how this hematologic cancer affects the general population show that it generally impacts patients over age 65 years.
What is the typical survival prognosis?
Thanks to research and therapeutic innovation, the prognosis has changed significantly over the past 20-25 years. Today, if a patient with multiple myeloma receives a diagnosis and does not exhibit poor prognostic characteristics (and this description fits approximately 70%-80% of patients with multiple myeloma), it is realistic to expect a survival exceeding 10 years. A few years ago, this outcome was unimaginable, but a significant amount of therapeutic innovation has made it possible. That’s why I emphasize that it is realistic to provide these data with such a positive outlook.
Is multiple myeloma a refractory type of cancer?
It was a refractory type of cancer. Twenty years ago, there were no treatment options, and therefore survival was around 2-3 years, because treatment mainly consisted of using alkylating agents and corticosteroids. This is what made it refractory.
With the emergence of new therapeutic innovations, patients have been responding better and their responses are lasting longer. Although there is still a group of patients, about 10%-15%, with a poor prognosis and refractory disease, those with standard risk are responding better to different therapies.
Although most patients will eventually exhaust the treatments, which until now were primarily triple-drug regimens (such as proteasome inhibitors, immunomodulators, and antiCD38 antibodies), the introduction of new therapies is extending the duration of responses.
Is the risk for relapse high?
It is very high, in the sense that almost all patients with multiple myeloma eventually relapse. However, we hope that there soon will be some patients who do not relapse.
What are the typical pathologic manifestations of this cancer? Does it affect everyone equally, or in specific ways in each person?
In multiple myeloma, we often say there are multiple myelomas. Clinically, the disease presents in most patients, around 80%, with two clinical manifestations: anemia and bone lesions. Less frequently, patients may also have kidney failure, hypercalcemia, and a higher tendency toward infection. Behind this rather common symptomatology, from a molecular and genetic perspective, each myeloma is practically unique, adding complexity to its treatment. Therefore, ultimately, myelomas end up being refractory.
Elranatamab is a new therapeutic tool. For which patients is it recommended?
It is a bispecific monoclonal antibody that corresponds to the new monotherapy strategies we have for treating patients with multiple myeloma. On the one hand, it targets damaged plasma cells, which are the patient’s tumor cells, and on the other, it binds the patient’s T cells and redirects them to the tumor niche. When this happens, the T cell activates and destroys the tumor cell.
This medication has been approved for patients with relapsed myeloma who have received traditional drugs for their treatment. We know well that patients who have already received proteasome inhibitors, immunomodulators, and anti-CD38 antibodies typically need something new after treatment. Before, there were no other options, and we would reuse what had been previously used. Now we have elranatamab, a bispecific monoclonal antibody targeting a new receptor that has shown significant responses as monotherapy.
More than 60% of patients respond, and more than 30% achieve complete remission. The key is the response duration and progression-free survival of almost a year and a half. This is the longest progression-free survival we have seen to date in previous lines. Therefore, it fills the needs we had for these relapsed or refractory myeloma patients.

When Childhood Cancer Survivors Face Sexual Challenges
Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.
This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.
Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.
The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
Characteristics and Mechanisms
Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.
As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.
Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.
Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects.
Sexual Function in CCS
A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.
The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.
Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.
In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.
The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
Factors Influencing Sexual Function
The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.
Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.
Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.
Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.
The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.
Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.
Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.
Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

FDA Issues Complete Response Letter for Myeloma Drug
On August 20, Regeneron announced that it had received a complete response letter from the FDA regarding its Biologics License Application for linvoseltamab, citing issues at a third-party manufacturer.
More specifically, Regeneron said in a company press release that the FDA issued the complete response letter based on findings from “a preapproval inspection at a third-party fill/finish manufacturer for another company’s product candidate.”
The third-party manufacturer told Regeneron it believes that the issues have been resolved, Regeneron said, and that facility is now awaiting a follow-up FDA inspection in the “coming months.”
Regeneron noted that this “anticipated outcome” from the FDA preapproval inspection had been disclosed previously during a company earnings call on August 1.
On that call, Regeneron had discussed the FDA’s concerns about the third-party manufacturer and anticipated that “any potential FDA approval for linvoseltamab is likely to be delayed beyond the August 22 PDUFA date.”
Regeneron had initially filed a Biologics License Application for its bispecific antibody in 2023, based on findings from the phase 1/2 single arm LINKER-MM1 trial.
In the latest published trial findings, investigators reported that, at a median follow-up of about 14 months, 71% of the 117 patients receiving 200 mg of linvoseltamab achieved an overall response, with 50% achieving a complete response. The probability of survival at 12 months was 75.3%.
This would have been the first approval for linvoseltamab, which would have joined two agents already on the US market for relapsed/refractory multiple myeloma: teclistamab (Tecvayli, Janssen) and elranatamab (Elrexfio, Pfizer).
Pricing information for linvoseltamab is not yet available, but its competitors teclistamab and elranatamab are reported to cost around $40,000 per month.

FDA Approves Axatilimab for Chronic GVHD
Chronic GVHD is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation that develops in about 50% of transplant recipients.
The first-in-class treatment for chronic GVHD is a monoclonal antibody that targets the colony-stimulating factor 1 (CSF-1) receptor. Approval for axatilimab followed priority review of Incyte’s Biologic License Application and was based on findings from the open-label phase 2 AGAVE-201 trial.
Study participants had chronic GVHD after allogeneic hematopoietic stem cell transplantation and had failed to respond to at least two prior lines of systemic therapy (median, four lines of therapy). Prior therapies included ruxolitinib, belumosudil, and ibrutinib in 74%, 23%, and 31% of patients, respectively. Overall, 239 patients were enrolled at 121 study sites and were randomly assigned 1:1:1 to three doses.
The FDA recommended dose of axatilimab is 0.3 mg/kg (to a maximum of 35 mg) as an intravenous infusion over 30 minutes every 2 weeks until disease progression or unacceptable toxicity. Other doses tested in the AGAVE-201 trial were 1 mg/kg every 2 weeks and 3 mg/kg every 4 weeks.
The trial measured overall response rate over the first six cycles (24 weeks). In the 79 patients who received the recommended 0.3-mg/kg dose, the overall response rate was 75%, and the median time to first response was 1.5 months (range, 0.9-5.1). The median duration of response — measured from first response to progression, death, or switch to a new systemic therapy for chronic GVHD — was 1.9 months.
In those who responded to the therapy, there were no deaths or new therapies required in 60% of patients.
The most common adverse reactions, occurring in 15% or more patients, included increased aspartate aminotransferase, infection (pathogen unspecified), increased alanine aminotransferase, decreased phosphate, decreased hemoglobin, musculoskeletal pain, increased lipase, fatigue, increased amylase, increased calcium, increased creatine phosphokinase, nausea, headache, diarrhea, cough, pyrexia, and dyspnea.
In the AGAVE-201 trial results, researchers noted that drug discontinuation from treatment-emergent adverse events occurred in 6% of patients in the 0.3-mg/kg cohort, in 22% in the 1-mg/kg cohort, and in 18% in the 3-mg/kg cohort. Fatal treatment-emergent adverse events occurred in 1.3% of patients in the 0.3-mg/kg cohort.
“Advanced chronic GVHD is characterized by the development of fibrotic tissue across multiple organ systems, including most commonly the skin and mucosa, and can be extremely difficult to treat, leading to high rates of morbidity and mortality,” lead study author Daniel Wolff, MD, PhD, head of the GVHD Center at the University Hospital Regensburg, Germany, said in a company press release. “I am excited that Niktimvo is designed to specifically target key drivers of inflammation and fibrosis in chronic GVHD, and I am highly encouraged by the robust responses observed across all organs and patient subgroups within the heavily pretreated population enrolled in the AGAVE-201 trial. I look forward to having a new and differentiated treatment option for my patients who need additional therapies to address this very difficult to manage, debilitating, disease.”

Chronic GVHD is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation that develops in about 50% of transplant recipients.
The first-in-class treatment for chronic GVHD is a monoclonal antibody that targets the colony-stimulating factor 1 (CSF-1) receptor. Approval for axatilimab followed priority review of Incyte’s Biologic License Application and was based on findings from the open-label phase 2 AGAVE-201 trial.
Study participants had chronic GVHD after allogeneic hematopoietic stem cell transplantation and had failed to respond to at least two prior lines of systemic therapy (median, four lines of therapy). Prior therapies included ruxolitinib, belumosudil, and ibrutinib in 74%, 23%, and 31% of patients, respectively. Overall, 239 patients were enrolled at 121 study sites and were randomly assigned 1:1:1 to three doses.

Immunotherapy May Be Overused in Dying Patients With Cancer
Chemotherapy has fallen out of favor for treating cancer toward the end of life. The toxicity is too high, and the benefit, if any, is often too low.
Immunotherapy, however, has been taking its place.
This means “there are patients who are getting immunotherapy who shouldn’t,” said Yale University, New Haven, Connecticut, surgical oncologist Sajid Khan, MD, senior investigator on a recent study that highlighted the growing use of these agents in patients’ last month of life.
What’s driving this trend, and how can oncologists avoid overtreatment with immunotherapy at the end of life?
The N-of-1 Patient
With immunotherapy at the end of life, “each of us has had our N-of-1” where a patient bounces back with a remarkable and durable response, said Don Dizon, MD, a gynecologic oncologist at Brown University, Providence, Rhode Island.
He recalled a patient with sarcoma who did not respond to chemotherapy. But after Dr. Dizon started her on immunotherapy, everything turned around. She has now been in remission for 8 years and counting.
The possibility of an unexpected or remarkable responder is seductive. And the improved safety of immunotherapy over chemotherapy adds to the allure.
Meanwhile, patients are often desperate. It’s rare for someone to be ready to stop treatment, Dr. Dizon said. Everybody “hopes that they’re going to be the exceptional responder.”
At the end of the day, the question often becomes: “Why not try immunotherapy? What’s there to lose?”
This thinking may be prompting broader use of immunotherapy in late-stage disease, even in instances with no Food and Drug Administration indication and virtually no supportive data, such as for metastatic ovarian cancer, Dr. Dizon said.
Back to Earth
The problem with the hopeful approach is that end-of-life turnarounds with immunotherapy are rare, and there’s no way at the moment to predict who will have one, said Laura Petrillo, MD, a palliative care physician at Massachusetts General Hospital, Boston.
Even though immunotherapy generally comes with fewer adverse events than chemotherapy, catastrophic side effects are still possible.
Dr. Petrillo recalled a 95-year-old woman with metastatic cancer who was largely asymptomatic.
She had a qualifying mutation for a checkpoint inhibitor, so her oncologist started her on one. The patient never bounced back from the severe colitis the agent caused, and she died of complications in the hospital.
Although such reactions with immunotherapy are uncommon, less serious problems caused by the agents can still have a major impact on a person’s quality of life. Low-grade diarrhea, for instance, may not sound too bad, but in a patient’s daily life, it can translate to six or more episodes a day.
Even with no side effects, prescribing immunotherapy can mean that patients with limited time left spend a good portion of it at an infusion clinic instead of at home. These patients are also less likely to be referred to hospice and more likely to be admitted to and die in the hospital.
And with treatments that can cost $20,000 per dose, financial toxicity becomes a big concern.
In short, some of the reasons why chemotherapy is not recommended at the end of life also apply to immunotherapy, Dr. Petrillo said.
Prescribing Decisions
Recent research highlights the growing use of immunotherapy at the end of life.
Dr. Khan’s retrospective study found, for instance, that the percentage of patients starting immunotherapy in the last 30 days of life increased by about fourfold to fivefold over the study period for the three cancers analyzed — stage IV melanoma, lung, and kidney cancers.
Among the population that died within 30 days, the percentage receiving immunotherapy increased over the study periods — 0.8%-4.3% for melanoma, 0.9%-3.2% for NSCLC, and 0.5%-2.6% for kidney cell carcinoma — prompting the conclusion that immunotherapy prescriptions in the last month of life are on the rise.
Prescribing immunotherapy in patients who ultimately died within 1 month occurred more frequently at low-volume, nonacademic centers than at academic or high-volume centers, and outcomes varied by practice setting.
Patients had better survival outcomes overall when receiving immunotherapy at academic or high-volume centers — a finding Dr. Khan said is worth investigating further. Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.
Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.
More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.
The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.
Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.
To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”
While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.
As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.
Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.
“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.
“Just because something can be done doesn’t always mean it should be done,” he said.
At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.
Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”
Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.
“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”
Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.

FDA Expands Darzalex Faspro Indication in Myeloma
Approval followed priority review and was based on efficacy and safety findings from the open-label PERSEUS trial involving 709 patients under age 70 years who were randomized to receive bortezomib, lenalidomide, and dexamethasone alone or in combination with daratumumab and hyaluronidase-fihj, according to the FDA.
Compared with bortezomib, lenalidomide, and dexamethasone alone, the addition of daratumumab and hyaluronidase-fihj resulted in a 60% reduction in the risk for disease progression or death (hazard ratio, 0.40). Median progression-free survival was not reached in either group.
Adverse reactions occurring in ≥ 20% of patients were peripheral neuropathy, fatigue, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash.
The recommended dosage for this indication is 1800 mg daratumumab and 30,000 units hyaluronidase, according to the full prescribing information.
Daratumumab and hyaluronidase-fihj, which was first approved in 2020, has a range of other indications in multiple myeloma.

Ancient Viruses in Our DNA Hold Clues to Cancer Treatment
according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.
The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)
Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.
But scientists weren’t exactly sure what that role was, said senior study author Edward Chuong, PhD, a genome biologist at the University of Colorado Boulder.
Most studies have looked at whether endogenous retroviruses code for proteins that influence cancer. But these ancient viral strands usually don’t code for proteins at all.
Dr. Chuong took a different approach. Inspired by scientists who’ve studied how viral remnants regulate positive processes (immunity, brain development, or placenta development), he and his team explored whether some might regulate genes that, once activated, help cancer thrive.
Borrowing from epigenomic analysis data (data on molecules that alter gene expression) for 21 cancers mapped by the Cancer Genome Atlas, the researchers identified 19 virus-derived DNA sequences that bind to regulatory proteins more in cancer cells than in healthy cells. All of these could potentially act as gene regulators that promote cancer.
The researchers homed in on one sequence, called LTR10, because it showed especially high activity in several cancers, including lung and colorectal cancer. This DNA segment comes from a virus that entered our ancestors’ genome 30 million years ago, and it’s activated in a third of colorectal cancers.
Using the gene editing technology clustered regularly interspaced short palindromic repeats (CRISPR), Dr. Chuong’s team silenced LTR10 in colorectal cancer cells, altering the gene sequence so it couldn’t bind to regulatory proteins. Doing so dampened the activity of nearby cancer-promoting genes.
“They still behaved like cancer cells,” Dr. Chuong said. But “it made the cancer cells more susceptible to radiation. That would imply that the presence of that viral ‘switch’ actually helped those cancer cells survive radiation therapy.”
Previously, two studies had found that viral regulators play a role in promoting two types of cancer: Leukemia and prostate cancer. The new study shows these two cases weren’t flukes. All 21 cancers they looked at had at least one of those 19 viral elements, presumably working as cancer enhancers.
The study also identified what activates LTR10 to make it promote cancer. The culprit is a regulator protein called mitogen-activated protein (MAP) kinase, which is overactivated in about 40% of all human cancers.
Some cancer drugs — MAP kinase inhibitors — already target MAP kinase, and they’re often the first ones prescribed when a patient is diagnosed with cancer, Dr. Chuong said. As with many cancer treatments, doctors don’t know why they work, just that they do.
“By understanding the mechanisms in the cell, we might be able to make them work better or further optimize their treatment,” he said.
“MAP kinase inhibitors are really like a sledgehammer to the cell,” Dr. Chuong said — meaning they affect many cellular processes, not just those related to cancer.
“If we’re able to say that these viral switches are what’s important, then that could potentially help us develop a more targeted therapy that uses something like CRISPR to silence these viral elements,” he said. Or it could help providers choose a MAP kinase inhibitor from among the dozens available best suited to treat an individual patient and avoid side effects.
Still, whether the findings translate to real cancer patients remains to be seen. “It’s very, very hard to go the final step of showing in a patient that these actually make a difference in the cancer,” Dr. Mager said.
More lab research, human trials, and at least a few years will be needed before this discovery could help treat cancer. “Directly targeting these elements as a therapy would be at least 5 years out,” Dr. Chuong said, “partly because that application would rely on CRISPR epigenome editing technology that is still being developed for clinical use.”

according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.
The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)
Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.

FROM SCIENCE ADVANCES
FDA Expands Darzalex Faspro Indication in Myeloma
Approval followed priority review and was based on efficacy and safety findings from the open-label PERSEUS trial involving 709 patients under age 70 years who were randomized to receive bortezomib, lenalidomide, and dexamethasone alone or in combination with daratumumab and hyaluronidase-fihj, according to the FDA.
Compared with bortezomib, lenalidomide, and dexamethasone alone, the addition of daratumumab and hyaluronidase-fihj resulted in a 60% reduction in the risk for disease progression or death (hazard ratio, 0.40). Median progression-free survival was not reached in either group.
Adverse reactions occurring in ≥ 20% of patients were peripheral neuropathy, fatigue, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash.
The recommended dosage for this indication is 1800 mg daratumumab and 30,000 units hyaluronidase, according to the full prescribing information.
Daratumumab and hyaluronidase-fihj, which was first approved in 2020, has a range of other indications in multiple myeloma.

Greater Transparency of Oncologists’ Pharma Relationships Needed
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
Experts: Professional Societies Should Further Limit Industry Payments
While partnerships between drug companies and physicians are necessary and have often been positive, more than disclosure is needed to minimize the risk of patient harm, according to an editorial published in March in JCO Oncology Practice. In it, Nina Niu Sanford, MD, a radiation oncologist UT Southwestern Medical Center, Dallas, and Bishal Gyawali, MD, PhD, a medical oncologist at Queen’s University, Kingston, Ontario, Canada, argue that following a specific blueprint could help mitigate financial conflicts of interest.
For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.
“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”

For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.
“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
