AACR Cancer Progress Report: Big Strides and Big Gaps
The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted.
One key area is funding. For the first time since 2016, federal funding for the National Institutes of Health (NIH) and National Cancer Institute (NCI) decreased in the past year. The cuts followed nearly a decade of funding increases that saw the NIH budget expand by nearly $15 billion, and that allowed for a “rapid pace and broad scope” of advances in cancer, AACR’s chief executive officer Margaret Foti, MD, PhD, said during a press briefing.
These recent cuts “threaten to curtail the medical progress seen in recent years and stymie future advancements,” said Dr. Foti, who called on Congress to commit to funding cancer research at significant and consistent levels to “maintain the momentum of progress against cancer.”
Inside the Report: Big Progress
Overall, advances in prevention, early detection, and treatment have helped catch more cancers earlier and save lives.
According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.
The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.
“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.”
The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.
“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
The Gaps
Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.
“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.
The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.
Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.
Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.
The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.
Financial toxicity remains prevalent as well.
The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.
For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.
On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
The Path Forward
Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.
“I am excited about what the future holds for cancer research, and especially for patient care,” she said.
However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.
Continued robust funding will help “to markedly improve cancer care, increase cancer survivorship, spur economic growth, and maintain the United States’ position as the global leader in science and medical research,” she added.
The AACR report specifically calls on Congress to:
- Appropriate at least $51.3 billion in fiscal year 2025 for the base budget of the NIH and at least $7.934 billion for the NCI.
- Provide $3.6 billion in dedicated funding for Cancer Moonshot activities through fiscal year 2026 in addition to other funding, consistent with the President’s fiscal year 2025 budget.
- Appropriate at least $472.4 million in fiscal year 2025 for the CDC’s Division of Cancer Prevention to support comprehensive cancer control, central cancer registries, and screening and awareness programs for specific cancers.
- Allocate $55 million in funding for the Oncology Center of Excellence at FDA in fiscal year 2025 to provide regulators with the staff and tools necessary to conduct expedited review of cancer-related medical products.
By working together with Congress and other stakeholders, “we will be able to accelerate the pace of progress and make major strides toward the lifesaving goal of preventing and curing all cancers at the earliest possible time,” Dr. Foti said. “I believe if we do that ... one day we will win this war on cancer.”

FDA Expands Indication for Amivantamab in Lung Cancer
Amivantamab with carboplatin and pemetrexed is now indicated for adults with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor (TKI).
The FDA has already approved first-line use of amivantamab in combination with carboplatin and pemetrexed in patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as reported by Medscape Medical News.
The second-line approval for amivantamab plus chemotherapy “may address the most common mechanisms of treatment resistance to third-generation EGFR TKIs, such as osimertinib, in the first line,” Martin Dietrich, MD, PhD, oncologist, Cancer Care Centers of Brevard in Florida, said in a company news release.
“This multitargeted combination extended progression-free survival (PFS) and improved overall response compared to chemotherapy alone, offering an important and effective new second-line option for patients,” Dr. Dietrich added.
The second-line indication is supported by the phase 3 MARIPOSA-2 study, which included 657 patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations and disease progression on or after receiving osimertinib.
The study demonstrated a 52% reduced risk of disease progression or death when amivantamab was added to carboplatin and pemetrexed (hazard ratio, 0.48).
Median PFS was 6.3 months with amivantamab vs 4.2 months with chemotherapy alone. The confirmed objective response rate was 53% in the amivantamab plus chemotherapy group vs 29% in the chemotherapy only group.
The most common adverse reactions, occurring in at least 20% of patients, were rash, infusion-related reactions, fatigue, nail toxicity, nausea, constipation, edema, stomatitis, decreased appetite, musculoskeletal pain, vomiting, and COVID-19 infection.
The company noted that amivantamab in combination with chemotherapy is the only category 1 treatment option in National Comprehensive Cancer Network clinical practice guidelines for patients with EGFR-mutated NSCLC who have progressed on osimertinib and who are symptomatic with multiple lesions.

Cancer Risk: Are Pesticides the New Smoking?
Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.
thus offering a limited perspective.
A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.
A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
Calculating Cancer Risk
Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:
- Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
- Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
- Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019
Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.
The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
Midwest Most Affected
While this model doesn’t establish causality or assess individual risk, it reveals regional trends in the association between pesticide use patterns and cancer incidence from a population-based perspective.
The Midwest, known for its high corn production, emerged as the region most affected by pesticide use. Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
Pesticides vs Smoking
The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.
The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.
This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
Expanding Scope of Research
Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.
The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.
Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
Pesticides vs Smoking
The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.
The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.
This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
Expanding Scope of Research
Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.
The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.
Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.
thus offering a limited perspective.
A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.
A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
Calculating Cancer Risk
Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:
- Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
- Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
- Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019
Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.
The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
Midwest Most Affected

FDA OKs Subcutaneous Atezolizumab Formulation for Multiple Cancer Indications
Approved indications include non–small cell lung cancer (NSCLC), SCLC, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma. Specific indications are available with the full prescribing information at Drugs@FDA.
This is the first programmed death–ligand 1 inhibitor to gain approval for subcutaneous administration.
“This approval represents a significant option to improve the patient experience,” Ann Fish-Steagall, RN, Senior Vice President of Patient Services at the LUNGevity Foundation stated in a Genentech press release.
Subcutaneous atezolizumab and hyaluronidase-tqjs was evaluated in the open-label, randomized IMscin001 trial of 371 adult patients with locally advanced or metastatic NSCLC who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy. Patients were randomized 2:1 to receive subcutaneous or IV administration until disease progression or unacceptable toxicity.
Atezolizumab exposure, the primary outcome measure of the study, met the lower limit of geometric mean ratio above the prespecified threshold of 0.8 (cycle 1C trough, 1.05; area under the curve for days 0-21, 0.87).
No notable differences were observed in overall response rate, progression-free survival, or overall survival between the two formulations, according to the FDA approval notice.
The confirmed overall response rate was 9% in the subcutaneous arm and 8% intravenous arm.
Adverse events of any grade occurring in at least 10% of patients were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.
The recommended dose for subcutaneous injection is one 15 mL injection, which contains 1875 mg of atezolizumab and 30,000 units of hyaluronidase.
Injections should be administered in the thigh over approximately 7 minutes every 3 weeks. By contrast, IV administration generally takes 30-60 minutes.

Osimertinib/Savolitinib Combo Shows Promise in NSCLC
according to results of the phase 2 FLOWERS study.
Compared with EGFR inhibitor osimertinib alone, the combination demonstrated a clinically meaningful improvement in the objective response rate — the study’s primary endpoint — with a positive trend in progression-free survival and a manageable safety profile.
About 30% patients with EGFR-mutated NSCLC fail to respond well to EGFR–tyrosine kinase inhibitors (TKIs), explained Jin-Ji Yang, MD, with Guangdong Lung Cancer Institute, Guangzhou, China, who reported the study results at the annual meeting of the World Conference on Lung Cancer.
Data suggested that de novo MET amplification occurs in up to 5% patients with treatment-naive, EGFR-mutated advanced NSCLC, and MET overexpression occurs in up to 15% these patients.
Coexistence of EGFR mutation and MET amplification/overexpression reduces sensitivity to EGFR-TKI therapy “and is likely the mechanism for mediating primary resistance to first-line EGFR-TKI monotherapy,” Dr. Yang explained in her presentation.
Osimertinib is a third-generation EGFR-TKI recommended as the first-line treatment for EGFR-mutant advanced NSCLC. Savolitinib is a highly selective MET-TKI which has demonstrated antitumor activity in various cancers with MET alterations.
The FLOWERS study is the first to test whether combining the two agents could improve efficacy and overcome MET-driven primary resistance in these patients.
The phase 2 study enrolled 44 treatment-naive patients with de novo MET-aberrant, EGFR-mutant, stage IIIB-IV NSCLC; 23 were randomly allocated to receive oral osimertinib (80 mg once daily) alone and 21 to receive oral osimertinib (80 mg once daily) plus savolitinib (300 mg twice daily).
At a median follow-up of 8.2 months, the objective response rate was 60.9% with osimertinib monotherapy vs 90.5% with combination therapy. The disease control rate was also better with the combination therapy than with monotherapy (95.2% vs 87%).
Median duration of response (not yet mature) was 8.4 months with monotherapy vs 18.6 months with combination therapy.
Preliminary progression-free survival data also showed a trend in favor of combination therapy over monotherapy (a median of 19.3 vs 9.3 months; hazard ratio, 0.59).
Most treatment-related adverse events were grade 1 or 2, and there were no fatal adverse events.
Treatment-related adverse events of grade 3 or higher were more common with combination therapy (57.1% vs 8.7%). The most common events with monotherapy were diarrhea (56.5%), rash (52.2%), and pruritus (43.5%) and with dual therapy were rash (52.4%), thrombocytopenia (52.4%), and peripheral edema (42.9%).
The results showed that the combination therapy has the potential to become a first-line treatment option for patients who do not respond well to EGFR-TKIs alone, Dr. Yang said in a press release.
Discussant for the study Paul Paik, MD, thoracic oncologist at Memorial Sloan Kettering Cancer Center in New York City, said this study “adds to data suggesting high MET expression might be a poor prognostic or predictive marker, the outcomes of which are improved with MET inhibition.”
He cautioned, however, that there appears to be “quality of life, side-effect trade-offs with dual MET plus EGFR TKI upfront.”
Dr. Paik said he looks forward to results from FLOWERS on serial circulating tumor DNA and formal androgen receptor testing, which “might aid in further assessing clonality and characterizing MET as a co-driver in this setting.”
The study was funded by AstraZeneca China. Dr. Yang had no disclosures. Dr. Paik disclosed relationships with EMD Serono, Bicara, Novartis, and Summit.

FROM WCLC 2024
The OCTAGON Project: A Novel VA-Based Telehealth Intervention for Oral Chemotherapy Monitoring
Background
Many Veterans with cancer experience substantial side effects related to their chemotherapy treatments resulting in impaired quality of life. Prompt management of such symptoms can improve adherence to therapy and potentially clinical outcomes. Previous studies in cancer patients have shown that mobile apps can improve symptom management and quality of life, though there are limited studies using oncology-focused apps in the VA population. The VA Annie App is an optimal platform for Veterans since it relies primarily on SMS-based texting and not on internet capabilities. This would address several well-known barriers to Veterans’ care access (limited internet connectivity, transportation) and enhance symptom reporting between infrequent provider visits. Providers can securely collect app responses within the VA system and there is already considerable VA developer experience with designing complex protocols. The OCTAGON project (Optimizing Cancer Care with Telehealth Assessment for Goal-Oriented Needs) will have the following goals: 1) To develop Annie App protocols to assist in management of cancer and/or chemotherapy-related symptoms (OCTAGON intervention), 2) To examine initial acceptability, feasibility, and Veteran-reported outcomes, 3) To explore short term effects on the utilization of VA encounters.
Methods
All patients who are primarily being managed at the VA Ann Arbor for their cancer therapy and are receiving one of the following therapies are considered eligible: EGFR inhibitors (lung cancer), antiandrogen therapies (prostate cancer), BTK inhibitors (lymphoma).
Discussion
Drug-specific protocols will be developed in conjunction with clinical pharmacists with experience in outpatient oral chemotherapy toxicity monitoring. Questions will have either a Yes/No, or numerical response. Interventions will be administered weekly for the first 3 months after enrollment, then decrease to monthly for a total of 6 months on protocol. Patients will be directed to contact their providers with any significant changes in tolerability. Planned data collected will include intervention question responses, adverse events, demographics, diagnosis, disease response, hospitalizations, treatment dose reductions or interruptions, provider and staff utilization. Survey responses to assess treatment acceptability (Treatment Acceptability/Adherence Scale), usability (System Usability Scale), general health (PROMIS-GH), and patient satisfaction will also be collected.

Barriers from Detection to Treatment in Lung Cancer: A Single Veteran Affair Institution Review
Background
Lung cancer is the leading cause of cancer related deaths in the United States. The impact of treatment delay proves difficult to quantify, but increased time to treatment and subsequent progression can limit a patient’s chance for curative intent therapy. Reducing time to treatment aims to improve patient outcome and experience. This study aims to identify the median timeframes that occur in the diagnosis and treatment of lung cancer patients within a single Veteran Affair (VA) Medical Center.
Methods
A retrospective chart review was conducted on 123 new primary lung cancer cases detected by imaging between January 1, 2019 and December 31, 2022 within a single VA medical center. Exclusions were preexisting lung cancer or other malignancy. The following data was collected: time to PET scan, referrals, and treatment initiation. KruskalWallis test and Mann-Whitney U test was employed to assess differences in treatment times based on treatment modality and disease stage, respectively
Results
The median time from first abnormal image to PET scan was 26 days. The median time from initial abnormal scan to treatment was 91 days. Treatment initiation was significantly shorter in late-state disease (IV, extensive stage) at 57 days compared to early-stage disease (I-III, limited stage) at 98.5 days (p= 0.00008). There was a difference in the median time from abnormal scan to treatment initiation based on treatment modality: chemotherapy, radiation therapy, and surgical intervention occurred at 60 days, 86 days, and 98 days, respectively (p= 0.005).
Conclusions
At our institution, patients with latestage lung cancer initiate therapy significantly faster than those diagnosed with early-stage cancer. We feel this is largely due to complex, multidisciplinary coordination of early-stage disease, in contrast to those diagnosed at later stage disease who are treated in a palliative, systemic fashion. This study was instrumental at identifying key areas along the process that can be improved upon. Based on this data, changes will be implemented and studied in effort to shorten time to treatment.

At our institution, patients with latestage lung cancer initiate therapy significantly faster than those diagnosed with early-stage cancer. We feel this is largely due to complex, multidisciplinary coordination of early-stage disease, in contrast to those diagnosed at later stage disease who are treated in a palliative, systemic fashion. This study was instrumental at identifying key areas along the process that can be improved upon. Based on this data, changes will be implemented and studied in effort to shorten time to treatment.
Ivonescimab: Possible New First-Line Standard in PD-L1–Positive Advanced NSCLC?
according to recent findings from the HARMONi-2 trial.
“This is the first randomized, phase 3 study to demonstrate a clinically significant improvement in efficacy with a novel drug compared to pembrolizumab in advanced NSCLC,” said study investigator Caicun Zhou, MD, PhD, with Shanghai Pulmonary Hospital in China,
The results highlight ivonescimab’s potential to become a “new standard of care” in advanced PD-L1–positive advanced NSCLC, said Dr. Zhou, who presented the analysis at the annual International Association for the Study of Lung Cancer (IASLC) World Conference on Lung Cancer in San Diego. Dr. Zhou is president-elect of the IASLC.
Ivonescimab (AK112) is a novel, potentially first-in-class investigational bispecific antibody that targets PD-1 and vascular endothelial growth factor (VEGF) developed by Akeso Biopharma, which funded the HARMONi-2 trial.
Conducted at 55 centers in China, HARMONi-2 enrolled 398 patients with untreated locally advanced or metastatic NSCLC, Eastern Cooperative Oncology Group Performance Status of 0 or 1, PD-L1 positive (with at least 1% of tumor cells expressing PD-L1), and no EGFR mutations or ALK rearrangements.
Patients were randomly allocated (1:1) to receive ivonescimab (20 mg/kg) or pembrolizumab (200 mg) every 3 weeks. The two groups were well balanced, and randomization was stratified by histology (squamous vs nonsquamous), clinical stage (IIIB/IIIC vs IV) and PD-L1 expression (PD-L1 of 1%-49% vs 50% or greater).
Dr. Zhou reported that patients who received ivonescimab were progression free for nearly twice as long as those on pembrolizumab — a median of 11.1 vs 5.8 months, indicating a 49% lower risk for progression or death (stratified hazard ratio [HR], 0.51; P < .0001).
The meaningful improvement in PFS with ivonescimab, compared with pembrolizumab, was “broadly consistent” in all prespecified subgroups, Dr. Zhou noted. That included patients with squamous NSCLC (HR, 0.48) and nonsquamous NSCLC (HR, 0.54), those with PD-L1 expression of 1%-49% (HR, 0.54) and 50% or higher (HR, 0.46), as well as those with liver metastases (HR, 0.47) and brain metastases (HR, 0.55).
The PFS benefit seen with ivonescimab in HARMONi-2 is “striking,” and the results “highlight the potential benefits of combined VEGF and PD-1 blockade together,” said John Heymach, MD, with the University of Texas MD Anderson Cancer Center in Houston, who served as discussant for the study.
Ivonescimab also led to a higher objective response rate (50% vs 38.5%) and disease control rate (89.9% vs 70.5%).
Grade 3 or higher treatment-related adverse events occurred in more patients receiving ivonescimab — 29.4% vs 15.6% on pembrolizumab. The difference largely stemmed from higher rates of proteinuria, hypertension, and lab abnormalities.
The rates of serious treatment-related adverse events were similar between the groups —20.8% in the ivonescimab group and 16.1% in the pembrolizumab group. Rates of grade 3 or higher immune-related adverse events were also similar, occurring in 7% of patients treated with ivonescimab and 8% of those receiving pembrolizumab.
In patients with squamous cell carcinoma, in particular, ivonescimab demonstrated a “very manageable” safety profile, Dr. Zhou noted. In this group, grade 3 or higher treatment-related adverse events occurred in 22.2% of patients (vs 18.7% receiving pembrolizumab).
Ivonescimab was associated with comparable but “numerically better” time to deterioration of global health status, based on the EORTC Core Quality of Life questionnaire, Dr. Zhou said.
Although the “really impressive and clinically meaningful” PFS benefits extended across different subgroups, “we await the overall survival results and additional studies done outside of China to confirm the benefit seen,” Dr. Heymach noted.
He also cautioned that, for patients with low to intermediate PD-L1 expression (1%-49%), pembrolizumab monotherapy “would not be the relevant comparator in the US and the rest of the world, and different study designs are going to be required for those populations.”
Based on the results of HARMONi-2, Akeso’s partner, Summit Therapeutics, plans to initiate HARMONi-7 in early 2025.
HARMONi-7 is currently planned as a multiregional, phase 3 clinical trial that will compare ivonescimab monotherapy to pembrolizumab monotherapy in patients with metastatic NSCLC whose tumors have high PD-L1 expression (50% or more).

FROM WCLC 2024
Do Clonal Hematopoiesis and Mosaic Chromosomal Alterations Increase Solid Tumor Risk?
Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.
These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
How This Study Differs From Others of Breast Cancer Risk Factors
“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.
In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.
But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.
“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”
In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?
To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.
In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.
More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.
The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.
“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.
“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.
“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.
Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
How Do Findings Compare With Those of the UK Biobank Study?
CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.
In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.
“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.
As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.
Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).
The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.
The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.
She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
Why Do Results Differ Between These Types of Studies?
Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.
“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.
“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.
Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?
“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”
Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.
“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
Future research and therapeutic development
Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.
“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.
Available data support both possibilities.
On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.
When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”
The presence of a causal association could be promising from a therapeutic standpoint.
“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.
Yet earlier intervention may still hold promise, according to experts.
“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.
The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.
“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.
Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?
“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”
Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.
“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
Future research and therapeutic development
Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.
“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.
Available data support both possibilities.
On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.
When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”
The presence of a causal association could be promising from a therapeutic standpoint.
“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.
Yet earlier intervention may still hold promise, according to experts.
“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.
The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.
These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
How This Study Differs From Others of Breast Cancer Risk Factors
“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.
In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.
But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.
“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”
In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?
To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.
In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.
More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.
The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.
“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.
“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.
“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.
Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
How Do Findings Compare With Those of the UK Biobank Study?
CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.
In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.
“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.
As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.
Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).
The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.
The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.
She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
Why Do Results Differ Between These Types of Studies?
Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.
“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.
