Efforts to combat hyperuricemia may find help from gut microbes, according to Dylan Dodd, MD, PhD, who spoke at the annual research symposium of the Gout, Hyperuricemia, and Crystal-Associated Disease Network.

Dodd is an assistant professor of pathology and microbiology and immunology at Stanford University, Palo Alto, California, where he studies novel metabolic pathways in microbes. “The idea is that we can leverage these novel pathways that microbes have as therapeutics to promote human health, and in particular for this meeting today, we’re focused on hyperuricemia and how microbes that break down purines may actually have a role as urate-lowering therapies,” Dodd said during his presentation.

Specifically, he highlighted the fact that some microbes found in the gut break down purines as a food source, producing both energy and molecular building blocks for their own use. Dietary purines, left intact, can otherwise be absorbed and metabolized by the body to produce urate.

Nucleic acids like DNA and RNA in the diet are first broken down by enzymes produced in the pancreas, resulting in purine nucleosides, which in turn are believed to be the source of purines absorbed in the small intestine and eventually into circulation, according to Dodd. “I really view urate in the intestine as being in equilibrium between being secreted into the lumen but also being reabsorbed, and specifically, as it pertains to microbes in the gut. If the microbes degrade the urate, then it will limit its reabsorption, and that could increase net excretion,” Dodd said.

There is evidence that some strains of Lactobacillus species, which are the most important group in the human gut, can metabolize purine nucleosides, he said. In recent years, researchers have screened for Lactobacillus species capable of metabolizing purine nucleosides. The research shows some strain-to-strain variation, but most are proprietary, making it impossible to conduct follow-up research. A small number of human trials have suggested efficacy, but they have generally been conducted in few patients with mixed results. “Overall, I think it’s promising that these lactobacilli probiotics could potentially be used as urate-lowering therapies,” Dodd said.

Aside from direct metabolism of purines, Dodd’s group has identified an additional pathway that some microbes can use to break down urate into short-chain fatty acids. His group cultured various purine nucleosides with various bacterial strains, including two Lactobacillus strains, under anaerobic conditions. The Lactobacillus strains did not degrade urate, but some bacterial species did. The group also found that Lactobacillus could convert nucleosides, including those derived from purines, into the smaller nucleobase compounds, but they did not consume the resultant purines. Some other types of bacteria consumed all purines “voraciously,” according to Dodd, and his team is working to identify the bacterial genetic pathways that drive the metabolic pathways. 

Such studies may open up various therapeutic pathways, he said. One is to employ Lactobacillus probiotics to convert purine nucleosides to their nucleobases, which could reduce absorption in the small intestine. Other bacteria could potentially be used to convert urate produced by paracellular reabsorption to short-chain fatty acids, which have potential benefits through their anti-inflammatory properties. Finally, probiotics could be engineered to degrade urate produced in the intestine. 

Dodd noted that probiotics would have the advantage of high patient acceptance and are generally regarded as safe. Some existing products might have purine-degrading capabilities but haven’t been tested, he said. However, there is strain-to-strain variation and the probiotic formulas would likely need to be optimized to reduce nucleobases. On the other hand, bacteria that degrade urate are likely safe since they have been found in the guts of healthy individuals. However, there are still potential safety concerns, and it is unknown if they could withstand the harsh conditions of the upper gastrointestinal tract or if they would remain active even in the presence of oxygen found in the small intestine, he said. 

During the Q&A period after his talk, Dodd was asked whether fructose consumption could suppress the function of anaerobic bacteria that naturally degrade purine. “When people talk about fructose-induced hyperuricemia, they talk about the ATP degradation in fructose metabolism in the liver or small intestine, [but] they never talk about this potential pathway in the gut,” the questioner said.

Dodd responded that his group found that some carbohydrates suppress urate degradation in some bacterial strains. “It’s certainly a possible mechanism that increased fructose intake could suppress microbial urate degradation in the gut, and that could contribute to hyperuricemia, but obviously more studies need to be done,” he said.

Another audience member wondered if antibiotic use could be tied to gout risk and whether serum urate levels might rise after antibiotic use. “Do you have any data on serum urate before and after antibiotic use, where you might expect to see changes which might support your hypothesis?” she asked. Dodd said that the group had done a retrospective analysis of data from Stanford’s medical records and did not find a change in serum urate after antibiotic exposure. However, a controlled feeding study of healthy individuals who later received antibiotics showed a large increase in urate levels, but the study did not include plasma samples. “It’s a really good question, and we hope to be able to follow that up,” he said.

Dodd disclosed no relevant financial relationships.

ASH 2024 Myeloma Studies: My Top 10 Picks

Article Type
Changed
Wed, 11/27/2024 - 02:16

As a doctor with a keen interest in myeloma who is looking ahead to the 2024 American Society of Hematology (ASH) annual meeting December 7-10 in San Diego, I’ve chosen 10 presentations that seem most likely to make the greatest impact on my thinking and practice.

First, let me place my selected studies in context by acknowledging my biases. As a clinician, I’m prone to choosing clinical rather than basic science or translational work — even if translational work might well end up exerting a pivotal impact on practice in the future. And now — in no particular order — here are my picks: 

 

IFM 2017-03 Phase 3 Study 

Frail patients are underrepresented in most myeloma studies, yet in this randomized trial for newly diagnosed myeloma, exclusively frail patients were enrolled. The trial compared daratumumab/lenalidomide to lenalidomide/dexamethasone, and the most recent follow/up shows a progression-free survival (PFS) (48.5 vs 21 months) and overall survival (OS) (not reached vs 36 months) benefit to daratumumab/lenalidomide. What I see in practice is that anti-CD38 monoclonal antibodies are the best-tolerated drugs in this space and should be the backbone of any regimen for frail patients. Steroids should be omitted as early as possible. Future trials may optimize what to give in addition to the anti-CD38 therapy, and how to adapt/escalate therapy to frailty and clinical status, as lenalidomide remains difficult for such patients to tolerate.

AQUILA Study 

This is a randomized, phase 3 comparison of daratumumab to observation for patients with smoldering myeloma. The endpoint was PFS. For context, similar studies done in asymptomatic CLL have shown improved PFS, but not OS, and the authors of such studies have concluded that improvement in PFS alone should not justify a change in approach.

Dr. Manni Mohyuddin

This study shows that daratumumab can improve laboratory markers and reduce progression (60-month PFS rates of 63.1% for daratumumab vs 40.8% with observation). However, several important caveats remain. The protocol only mandated spine/pelvis MRI imaging, not whole-body MRI imaging, and such imaging was only performed once a year, which may not be frequent enough to catch lesions at an earlier stage. These details have important implications, as previous research shows that up to half of lesions can be missed by doing only a spine MRI, as opposed to a whole-body MRI. 

All of this means that had more comprehensive imaging been done, many more patients may have been diagnosed with myeloma. Such patients may have been undertreated, and single agent daratumumab, with a response rate of just 63%, may not have been enough. Conversely, some patients may also have been overtreated using this approach, as the protocol allowed patients who had been diagnosed with smoldering myeloma up to 5 years earlier to be enrolled. Many of these people could have had indolent disease for years prior to enrollment and may not have ever progressed. 

Further information is needed to help us understand this study better. What was the nature of the progression events: asymptomatic lab changes or morbid end organ damage? Was daratumumab given when patients in the control arm progressed to myeloma? My concern is that if patients in the control arm do not universally receive modern daratumumab-containing therapies when they develop myeloma, then an overall survival advantage may be shown simply because patients in the intervention arm are getting a good drug earlier in the disease, while those in the control arm are not getting a good drug at all. Nevertheless, despite these limitations, it is likely this trial will lead to regulatory approval of daratumumab in this space, and lots of discussions from patients and clinicians alike.

 

Extended Follow-Up of Anito-Cel in its First In-Human study 

Two chimeric antigen receptor therapy (CAR-T) products are currently approved for myeloma. Cilta-cel is clearly effective but is associated with problematic late-onset neurological toxicities. Ide-cel appears much less effective. There is clearly a need for a product that is both effective and safe.

Anito-cel has two relevant abstracts this meeting that show much promise. Extended follow-up of anito-cel from its first in human study shows a promising 27-month PFS of 52%, and with no cases of delayed neurotoxicity. I also eagerly await further information from the registrational single-arm study of anti-cel being presented at ASH 2024, which should (hopefully) lead to its accelerated approval.

 

Screening for Myeloma for all People With Vertebral Fractures Likely Unnecessary 

This elegant study of over 9,000 people with vertebral fractures shows that absolute risks for myeloma were 0.43% and 0.63% in women and men with grade 2-3 fractures, respectively, indicating that there is likely little benefit in evaluating asymptomatic individuals with incidentally discovered vertebral fractures for myeloma, unless other features are present. Spread the word.

Further Information on Cevostamab, Another Bispecific Option

We do need effective treatments for targets beyond just BCMA and GPRC5D. Cevostamab, a bispecific targeting FCRH5, represents another option, with updated data on 167 patients. With an overall response rate of 43% (duration of response, 10 months), and a response rate of about 30% in those with prior bispecific exposure, this data helps us contextualize expected benefits as we look forward to the eventual approval of this drug. The efficacy is relatively modest in those who have already progressed on bispecifics, but cevostamab would still be a welcome addition to our arsenal.

Is GPRC5D a Better Target for Car T Rather Than Bispecifics? 

Our currently available GPRC5D bispecific (talquetamab) leads to high rates of skin, oral, and nail toxicity. This drug can also bring significant weight loss. These side effects make me consider that continuous targeting of GPRC5D through a bispecific may not be ideal, and that GPRC5D may be better as a one-time CAR T target. At ASH 2024, we will have 15-month follow-up data from BMS-986393, a GPRC5D CAR T. Response rates for this heavily pretreated population (76% of whom had triple refractory disease) were at 87%, with a median PFS of 14.5 months. Only 6% of patients experienced treatment-related weight loss, and nail (19%), skin (30%), and oral (31%) toxicities were relatively low. I look forward to updated data, as well as data on the resolution of the toxicities seen.

Daratumumab, a Game-Changer for AL Amyloidosis 

A truly effective drug given early can change the natural history of disease, even if patients in the control arm only receive the drug later. A case in point is daratumumab. The 5-year survival rate was 76.1% for the daratumumab/cyclophosphamide/bortezomib/dexamethasone arm and 64.7% for cyclophosphamide/bortezomib/dexamethasone arm. This happened despite the fact that 67% of the control arm patients (among those who received therapy) went on to receive daratumumab later in the disease course.

Understanding how SMM Progresses to MM 

We often hear that we should treat SMM and not just watch carefully because fractures may suddenly happen, or a patient may end up on dialysis. What this retrospective study tells us that amongst 427 patients with SMM, 42 had progression to myeloma, and amongst those 42, only 1 developed renal dysfunction (unclear if this resolved), and only 1 had lytic lesions that were symptomatic. The remainder were all asymptomatic lab and imaging changes. This is a retrospective study, and one should assume that follow-up was thus highly variable. It does not appear that diffusion weighted whole-body MRI imaging (our most sensitive imaging test) was employed universally or very frequently. Nevertheless, these powerful findings reassure us that, with close observation, morbidity is unlikely. Our group has designed a prospective study incorporating frequent diffusion weighted whole body MRI imaging to formally test this hypothesis (SPOTLIGHT, NCT06212323). 

The Underperformance of Daratumumab/Lenalidomide/Dexamethasone in the Real World 

At every major meeting I am reminded of the disconnect between real-world efficacy and clinical trial efficacy. Case in point: In this Austrian experience, daratumumab/lenalidomide/dexamethasone led to a PFS of 22.7 months vs 61.9 months in the MAIA trial of daratumumab/lenalidomide/dexamethasone. Such a sobering difference! And if you think this is an isolated experience, even in a US real-world cohort, consider that in a recently published comparative study dara/len/dex underperformed, although the time to next treatment or death was longer (37.8 months).

Delayed Neurotoxicity may not be Just a Consequence of high tumor burden 

We currently think that some of the scariest side effects of cilta-cel, such as delayed neurotoxicity, may be a consequence of a high number of cancer cells and may be prevented by better disease control at the time of infusion. This study, a sobering analysis of 52 patients with delayed neurotoxicity occurring after CAR T, included 8 patients (15%) who were not heavily pretreated, and all had less than 5% plasma cells at the time of infusion. None of these patients had extramedullary disease. This result worries me, especially because cilta-cel is being studied and is poised for future approval in earlier line settings. It suggests that this toxicity may not always be a product of disease burden, contrary to our current belief.

I will be paying close attention to these 10 myeloma studies at ASH 2024, where I look forward to meeting you and learning more.Dr. Mohyuddin is assistant professor in the multiple myeloma program at the Huntsman Cancer Institute at the University of Utah, Salt Lake City.

The Underperformance of Daratumumab/Lenalidomide/Dexamethasone in the Real World 

At every major meeting I am reminded of the disconnect between real-world efficacy and clinical trial efficacy. Case in point: In this Austrian experience, daratumumab/lenalidomide/dexamethasone led to a PFS of 22.7 months vs 61.9 months in the MAIA trial of daratumumab/lenalidomide/dexamethasone. Such a sobering difference! And if you think this is an isolated experience, even in a US real-world cohort, consider that in a recently published comparative study dara/len/dex underperformed, although the time to next treatment or death was longer (37.8 months).

Delayed Neurotoxicity may not be Just a Consequence of high tumor burden 

We currently think that some of the scariest side effects of cilta-cel, such as delayed neurotoxicity, may be a consequence of a high number of cancer cells and may be prevented by better disease control at the time of infusion. This study, a sobering analysis of 52 patients with delayed neurotoxicity occurring after CAR T, included 8 patients (15%) who were not heavily pretreated, and all had less than 5% plasma cells at the time of infusion. None of these patients had extramedullary disease. This result worries me, especially because cilta-cel is being studied and is poised for future approval in earlier line settings. It suggests that this toxicity may not always be a product of disease burden, contrary to our current belief.

I will be paying close attention to these 10 myeloma studies at ASH 2024, where I look forward to meeting you and learning more.Dr. Mohyuddin is assistant professor in the multiple myeloma program at the Huntsman Cancer Institute at the University of Utah, Salt Lake City.

As a doctor with a keen interest in myeloma who is looking ahead to the 2024 American Society of Hematology (ASH) annual meeting December 7-10 in San Diego, I’ve chosen 10 presentations that seem most likely to make the greatest impact on my thinking and practice.

First, let me place my selected studies in context by acknowledging my biases. As a clinician, I’m prone to choosing clinical rather than basic science or translational work — even if translational work might well end up exerting a pivotal impact on practice in the future. And now — in no particular order — here are my picks: 

 

IFM 2017-03 Phase 3 Study 

Frail patients are underrepresented in most myeloma studies, yet in this randomized trial for newly diagnosed myeloma, exclusively frail patients were enrolled. The trial compared daratumumab/lenalidomide to lenalidomide/dexamethasone, and the most recent follow/up shows a progression-free survival (PFS) (48.5 vs 21 months) and overall survival (OS) (not reached vs 36 months) benefit to daratumumab/lenalidomide. What I see in practice is that anti-CD38 monoclonal antibodies are the best-tolerated drugs in this space and should be the backbone of any regimen for frail patients. Steroids should be omitted as early as possible. Future trials may optimize what to give in addition to the anti-CD38 therapy, and how to adapt/escalate therapy to frailty and clinical status, as lenalidomide remains difficult for such patients to tolerate.

AQUILA Study 

This is a randomized, phase 3 comparison of daratumumab to observation for patients with smoldering myeloma. The endpoint was PFS. For context, similar studies done in asymptomatic CLL have shown improved PFS, but not OS, and the authors of such studies have concluded that improvement in PFS alone should not justify a change in approach.

Dr. Manni Mohyuddin

This study shows that daratumumab can improve laboratory markers and reduce progression (60-month PFS rates of 63.1% for daratumumab vs 40.8% with observation). However, several important caveats remain. The protocol only mandated spine/pelvis MRI imaging, not whole-body MRI imaging, and such imaging was only performed once a year, which may not be frequent enough to catch lesions at an earlier stage. These details have important implications, as previous research shows that up to half of lesions can be missed by doing only a spine MRI, as opposed to a whole-body MRI. 

All of this means that had more comprehensive imaging been done, many more patients may have been diagnosed with myeloma. Such patients may have been undertreated, and single agent daratumumab, with a response rate of just 63%, may not have been enough. Conversely, some patients may also have been overtreated using this approach, as the protocol allowed patients who had been diagnosed with smoldering myeloma up to 5 years earlier to be enrolled. Many of these people could have had indolent disease for years prior to enrollment and may not have ever progressed. 

Further information is needed to help us understand this study better. What was the nature of the progression events: asymptomatic lab changes or morbid end organ damage? Was daratumumab given when patients in the control arm progressed to myeloma? My concern is that if patients in the control arm do not universally receive modern daratumumab-containing therapies when they develop myeloma, then an overall survival advantage may be shown simply because patients in the intervention arm are getting a good drug earlier in the disease, while those in the control arm are not getting a good drug at all. Nevertheless, despite these limitations, it is likely this trial will lead to regulatory approval of daratumumab in this space, and lots of discussions from patients and clinicians alike.

 

Extended Follow-Up of Anito-Cel in its First In-Human study 

Two chimeric antigen receptor therapy (CAR-T) products are currently approved for myeloma. Cilta-cel is clearly effective but is associated with problematic late-onset neurological toxicities. Ide-cel appears much less effective. There is clearly a need for a product that is both effective and safe.

Anito-cel has two relevant abstracts this meeting that show much promise. Extended follow-up of anito-cel from its first in human study shows a promising 27-month PFS of 52%, and with no cases of delayed neurotoxicity. I also eagerly await further information from the registrational single-arm study of anti-cel being presented at ASH 2024, which should (hopefully) lead to its accelerated approval.

 

Screening for Myeloma for all People With Vertebral Fractures Likely Unnecessary 

This elegant study of over 9,000 people with vertebral fractures shows that absolute risks for myeloma were 0.43% and 0.63% in women and men with grade 2-3 fractures, respectively, indicating that there is likely little benefit in evaluating asymptomatic individuals with incidentally discovered vertebral fractures for myeloma, unless other features are present. Spread the word.

Further Information on Cevostamab, Another Bispecific Option

We do need effective treatments for targets beyond just BCMA and GPRC5D. Cevostamab, a bispecific targeting FCRH5, represents another option, with updated data on 167 patients. With an overall response rate of 43% (duration of response, 10 months), and a response rate of about 30% in those with prior bispecific exposure, this data helps us contextualize expected benefits as we look forward to the eventual approval of this drug. The efficacy is relatively modest in those who have already progressed on bispecifics, but cevostamab would still be a welcome addition to our arsenal.

Is GPRC5D a Better Target for Car T Rather Than Bispecifics? 

Our currently available GPRC5D bispecific (talquetamab) leads to high rates of skin, oral, and nail toxicity. This drug can also bring significant weight loss. These side effects make me consider that continuous targeting of GPRC5D through a bispecific may not be ideal, and that GPRC5D may be better as a one-time CAR T target. At ASH 2024, we will have 15-month follow-up data from BMS-986393, a GPRC5D CAR T. Response rates for this heavily pretreated population (76% of whom had triple refractory disease) were at 87%, with a median PFS of 14.5 months. Only 6% of patients experienced treatment-related weight loss, and nail (19%), skin (30%), and oral (31%) toxicities were relatively low. I look forward to updated data, as well as data on the resolution of the toxicities seen.

Daratumumab, a Game-Changer for AL Amyloidosis 

A truly effective drug given early can change the natural history of disease, even if patients in the control arm only receive the drug later. A case in point is daratumumab. The 5-year survival rate was 76.1% for the daratumumab/cyclophosphamide/bortezomib/dexamethasone arm and 64.7% for cyclophosphamide/bortezomib/dexamethasone arm. This happened despite the fact that 67% of the control arm patients (among those who received therapy) went on to receive daratumumab later in the disease course.

Understanding how SMM Progresses to MM 

We often hear that we should treat SMM and not just watch carefully because fractures may suddenly happen, or a patient may end up on dialysis. What this retrospective study tells us that amongst 427 patients with SMM, 42 had progression to myeloma, and amongst those 42, only 1 developed renal dysfunction (unclear if this resolved), and only 1 had lytic lesions that were symptomatic. The remainder were all asymptomatic lab and imaging changes. This is a retrospective study, and one should assume that follow-up was thus highly variable. It does not appear that diffusion weighted whole-body MRI imaging (our most sensitive imaging test) was employed universally or very frequently. Nevertheless, these powerful findings reassure us that, with close observation, morbidity is unlikely. Our group has designed a prospective study incorporating frequent diffusion weighted whole body MRI imaging to formally test this hypothesis (SPOTLIGHT, NCT06212323). 

The Underperformance of Daratumumab/Lenalidomide/Dexamethasone in the Real World 

At every major meeting I am reminded of the disconnect between real-world efficacy and clinical trial efficacy. Case in point: In this Austrian experience, daratumumab/lenalidomide/dexamethasone led to a PFS of 22.7 months vs 61.9 months in the MAIA trial of daratumumab/lenalidomide/dexamethasone. Such a sobering difference! And if you think this is an isolated experience, even in a US real-world cohort, consider that in a recently published comparative study dara/len/dex underperformed, although the time to next treatment or death was longer (37.8 months).

Veterans’ Well-Being Tools Aim to Improve Quality of Life

Article Type
Changed
Wed, 11/27/2024 - 02:21

Could assessing the well-being of older patients create better treatment plans?

Researchers with the US Department of Veterans Affairs posit that doing so just might improve patient quality of life.

In an article in Medical Care, Dawne Vogt, PhD, and her colleagues described two surveys of well-being developed for use in clinical settings.

“Well-Being Signs” (WBS), a 1-minute screening, asks patients about how satisfied they are with the most important parts of their daily life, which could include time with family. It also asks how regularly involved they are in the activities and their level of functioning.

“Well-Being Brief” (WBB) is self-administered and asks more in-depth questions about finances, health, social relationships, and vocation. Clinicians can use the tool to make referrals to appropriate services like counseling or resources like senior centers.

“They’re not things that we’ve historically paid a lot of attention to, at least in the healthcare setting,” said Vogt, a research psychologist in the Women’s Health Sciences Division of the VA Boston Healthcare System in Massachusetts. “A growing body of research shows that they have really big implications for health.”

The two approaches stem from an increased awareness of the relationship between social determinants of health and outcomes. Both screenings can be implemented more effectively in a clinical setting than other measures because of their brevity and ease of use, she said.

Vogt shared that anecdotally, she finds patients are pleasantly surprised by the questionnaires “because they’re being seen in a way that they don’t always feel like they’re seen.”

Vogt said that the two well-being measurements are more nuanced than standard screenings for depression.

“A measure of depression tells you something much more narrow than a measure of well-being tells you,” she said, adding that identifying problem areas early can help prevent developing mental health disorders. For example, Vogt said that veterans with higher well-being are less likely to develop posttraumatic stress disorder when exposed to trauma.

The WBS has been validated, while the WBB questionnaire awaits final testing.

James Michail, MD, a family and geriatric physician with Providence Health & Services in Los Angeles, California, said he views the well-being screeners as launching points into discussing whether a treatment is enhancing or inhibiting a patient’s life.

“We have screenings for everything else but not for wellness, and the goal of care isn’t necessarily always treatment,” Michail said. “It’s taking the whole person into consideration. There’s a person behind the disease.”

Kendra Segura, MD, an obstetrician-gynecologist in Los Angeles, said she is open to using a well-being screener. Usually, building repertoire with a patient takes time, and sometimes only then can it allow for a more candid assessment of well-being.

“Over the course of several visits, that is when patients open up,” she said. “It’s when that starts to happen where they start to tell you about their well-being. It’s not an easy thing to establish.”

The authors of the article reported no relevant financial relationships.

FDA Approves Bispecific HER2 Antibody for Biliary Tract Cancer

Article Type
Changed
Wed, 11/27/2024 - 02:47

The Food and Drug Administration (FDA) has approved zanidatamab (Ziihera, Jazz Pharmaceuticals) as monotherapy for previously treated, unresectable or metastatic HER2-positive biliary tract cancer (BTC). This approval makes the bispecific antibody the first HER2-targeted treatment to carry the indication. 

Zanidatamab binds two separate regions on the HER2 cell surface protein, crosslinking neighboring HER2 proteins, blocking HER2 signaling, and inducing cytotoxic immune responses.

The FDA simultaneously announced that it has also approved VENTANA PATHWAY anti–HER2/neu (4B5) Rabbit Monoclonal Primary Antibody (Ventana Medical Systems, Inc./Roche Diagnostics) as a companion diagnostic device to aid in identifying patients with BTC who may be eligible for treatment with zanidatamab.

 

Zanidatamab Trial Results

The approval of zanidatamab was based on the phase 2b HERIZON-BTC-01 trial— which was open-label, multicenter, and single-arm — involving 62 patients with unresectable or metastatic HER2-positive (IHC3+) BTC. In this trial, zanidatamab 20 mg/kg was administered every 2 weeks to patients who had received gemcitabine-containing chemotherapy previously but not a HER2-targeted therapy.

The objective response rate was 52%, and the median duration of response was 14.9 months, according to the statement from the FDA.

The life expectancy for advanced BTC treated in the second line with standard chemotherapy is approximately 6-9 months, according to Jazz Pharmaceuticals

 

Boxed Warning and Adverse Events

The prescribing information contains a boxed warning for embryo-fetal toxicity. The most common adverse reactions reported in at least 20% of patients who received zanidatamab were diarrhea, infusion-related reactions, abdominal pain, and fatigue.

The recommended zanidatamab dose is 20 mg/kg, administered as an intravenous infusion once every 2 weeks until progression or unacceptable toxicity. 

Jazz Pharmaceuticals’ application was granted priority review, breakthrough therapy designation, and orphan drug designation.

An ongoing phase 3 trial, HERIZON-BTC-302, is testing zanidatamab in combination with standard-of-care therapy in the first-line setting for advanced or metastatic HER2-positive BTC. The bispecific antibody is also being developed for HER2-positive advanced/metastatic gastroesophageal adenocarcinoma.

NCCN Expands Cancer Genetic Risk Assessment Guidelines

Article Type
Changed
Wed, 11/27/2024 - 02:19

The National Comprehensive Cancer Network (NCCN) has expanded two cancer genetic risk assessment guidelines to meet the growing understanding of hereditary cancer risk and use of genetic tests in cancer prevention, screening, and treatment. 

Additional cancer types were included in the title and content for both guidelines. Prostate cancer was added to Genetic/Familial High-Risk Assessment: Breast, Ovarian, Pancreatic, and Prostate, and endometrial and gastric cancer were added to Genetic/Familial High-Risk Assessment: Colorectal, Endometrial, and Gastric.

For these cancers, the expanded guidelines include information on when genetic testing is recommended and what type of testing may be best. These guidelines also detail the hereditary conditions and genetic mutations associated with elevated cancer risk and include appropriate “next steps” for individuals who have them, which may involve increased screening or prevention surgeries.

“These updates include the spectrum of genes associated with genetic syndromes, the range of risk associated with each pathogenic variant, the improvements in screening and prevention strategies, the role of genetic data to inform cancer treatment, and the expansion of the role of genetic counseling as this field moves forward,” Mary B. Daly, MD, PhD, with Fox Chase Cancer Center, Philadelphia, Pennsylvania, said in a news release. Daly chaired the panel that updated the breast, ovarian, pancreatic, and prostate cancer guidelines.

Oncologists should, for instance, ask patients about their family and personal history of cancer and known germline variants at time of initial diagnosis. With prostate cancer, if patients meet criteria for germline testing, multigene testing should include a host of variants, including BRCA1, BRCA2, ATM, PALB2, CHEK2, HOXB13, MLH1, MSH2, MSH6, and PMS2.

The updated guidelines on genetic risk assessment of colorectal, endometrial, and gastric cancer include new recommendations to consider for hereditary cancer screening in patients with newly diagnosed endometrial cancer, for evaluating and managing CDH1-associated gastric cancer risk, and for managing gastric cancer risk in patients with APC pathogenic variants. 

For CDH1-associated gastric cancer, for instance, the guidelines recommend carriers be referred to institutions with expertise in managing risks for cancer associated with CDH1, “given the still limited understanding and rarity of this syndrome.” 

“These expanded guidelines reflect the recommendations from leading experts on genetic testing based on the latest scientific research across the cancer spectrum, consolidated into two convenient resources,” said NCCN CEO Crystal S. Denlinger, MD, with Fox Chase Cancer Center, in a news release

“This information is critical for guiding shared decision-making between health care providers and their patients, enhancing screening practices as appropriate, and potentially choosing options for prevention and targeted treatment choices. Genetic testing guidelines enable us to better care for people with cancer and their family members,” Denlinger added.

“These updates include the spectrum of genes associated with genetic syndromes, the range of risk associated with each pathogenic variant, the improvements in screening and prevention strategies, the role of genetic data to inform cancer treatment, and the expansion of the role of genetic counseling as this field moves forward,” Mary B. Daly, MD, PhD, with Fox Chase Cancer Center, Philadelphia, Pennsylvania, said in a news release. Daly chaired the panel that updated the breast, ovarian, pancreatic, and prostate cancer guidelines.

Oncologists should, for instance, ask patients about their family and personal history of cancer and known germline variants at time of initial diagnosis. With prostate cancer, if patients meet criteria for germline testing, multigene testing should include a host of variants, including BRCA1, BRCA2, ATM, PALB2, CHEK2, HOXB13, MLH1, MSH2, MSH6, and PMS2.

The updated guidelines on genetic risk assessment of colorectal, endometrial, and gastric cancer include new recommendations to consider for hereditary cancer screening in patients with newly diagnosed endometrial cancer, for evaluating and managing CDH1-associated gastric cancer risk, and for managing gastric cancer risk in patients with APC pathogenic variants. 

For CDH1-associated gastric cancer, for instance, the guidelines recommend carriers be referred to institutions with expertise in managing risks for cancer associated with CDH1, “given the still limited understanding and rarity of this syndrome.” 

“These expanded guidelines reflect the recommendations from leading experts on genetic testing based on the latest scientific research across the cancer spectrum, consolidated into two convenient resources,” said NCCN CEO Crystal S. Denlinger, MD, with Fox Chase Cancer Center, in a news release

“This information is critical for guiding shared decision-making between health care providers and their patients, enhancing screening practices as appropriate, and potentially choosing options for prevention and targeted treatment choices. Genetic testing guidelines enable us to better care for people with cancer and their family members,” Denlinger added.

The National Comprehensive Cancer Network (NCCN) has expanded two cancer genetic risk assessment guidelines to meet the growing understanding of hereditary cancer risk and use of genetic tests in cancer prevention, screening, and treatment. 

Additional cancer types were included in the title and content for both guidelines. Prostate cancer was added to Genetic/Familial High-Risk Assessment: Breast, Ovarian, Pancreatic, and Prostate, and endometrial and gastric cancer were added to Genetic/Familial High-Risk Assessment: Colorectal, Endometrial, and Gastric.

For these cancers, the expanded guidelines include information on when genetic testing is recommended and what type of testing may be best. These guidelines also detail the hereditary conditions and genetic mutations associated with elevated cancer risk and include appropriate “next steps” for individuals who have them, which may involve increased screening or prevention surgeries.

Which Breast Cancer Patients Can Skip Postop Radiotherapy?

Article Type
Changed
Wed, 11/27/2024 - 01:37

TOPLINE: 

The Profile for the Omission of Local Adjuvant Radiation (POLAR) biomarker, a 16-gene molecular signature, can help predict locoregional recurrence in patients with ER-positive early breast cancer following breast-conserving surgery as well as which patients will benefit most from adjuvant radiotherapy. Overall, patients with a high POLAR score derived a significant benefit from adjuvant radiotherapy, while those with a low score did not and might consider forgoing radiotherapy.

METHODOLOGY:

  • Radiation therapy after breast-conserving surgery has been shown to reduce the risk for locoregional recurrence and is a standard approach to manage early breast cancer. However, certain patients with low locoregional recurrence risks may not necessarily benefit from adjuvant radiation, but there has not been a commercially available molecular test to help identify which patients that might be.
  • In the current analysis, researchers assessed whether the POLAR biomarker test could reliably predict locoregional recurrence as well as identify patients who would not benefit from radiotherapy.
  • The meta-analysis used data from three randomized trials — Scottish Conservation Trial, SweBCG91-RT, and Princess Margaret RT trial — to validate the POLAR biomarker test in patients with low-risk, HR-positive, HER2-negative, node-negative breast cancer.
  • The analysis included 623 patients (ages 50-76), of whom 429 (69%) had high POLAR scores and 194 (31%) had low POLAR scores.
  • The primary endpoint was the time to locoregional recurrence, and secondary endpoints included evaluating POLAR as a prognostic factor for locoregional recurrence in patients without radiotherapy and effect of radiotherapy in patients with low and high POLAR scores.

TAKEAWAY:

  • Patients with high POLAR scores demonstrated a significant benefit from radiotherapy. The 10-year locoregional recurrence rate was 7% with radiotherapy vs 20% without radiotherapy (hazard ratio [HR], 0.37; P < .001).
  • Patients with low POLAR scores, however, did not experience a significant benefit from radiotherapy. In this group, the 10-year locoregional recurrence rates were similar with and without radiotherapy (7% vs 5%, respectively; HR, 0.92; P = .832), indicating that radiotherapy could potentially be omitted for these patients.
  • Among patients who did not receive radiotherapy (n = 309), higher POLAR scores predicted a greater risk for recurrence, suggesting the genomic signature has prognostic value. There is no evidence, however, that POLAR predicts radiotherapy benefit or predicts patients’ risk for distant metastases or mortality.

IN PRACTICE:

“This meta-analysis from three randomized controlled trials clearly demonstrates the clinical potential for POLAR to be used in smaller estrogen receptor positive node negative breast cancer patients to identify those women who do not appear to benefit from the use of post-operative adjuvant radiotherapy,” the authors wrote. “ This classifier is an important step towards molecularly-stratified targeting of the use of radiotherapy.”

SOURCE:

The study, led by Per Karlsson, MD, PhD, University of Gothenburg, Sweden, was published online in the Journal of the National Cancer Institute.

LIMITATIONS:

One cohort (SweBCG) had limited use of adjuvant systemic therapy, which could affect generalizability. Additionally, low numbers of patients with low POLAR scores in two trials could affect the observed benefit of radiotherapy.

DISCLOSURES:

This study was supported by the Breast Cancer Institute Fund (Edinburgh and Lothians Health Foundation), Canadian Institutes of Health Research, Exact Sciences Corporation, PFS Genomics, Swedish Cancer Society, and Swedish Research Council. One author reported being an employee and owning stock or stock options or patents with Exact Sciences. Several authors reported having various ties with various sources including Exact Sciences.

Managing Rosacea: Tips for Reducing Facial Erythema, Flushing

Article Type
Changed
Wed, 11/27/2024 - 01:36

When patients with rosacea consult Julie C. Harper, MD, about persistent facial erythema, she often recommends brimonidine 0.33% gel or oxymetazoline 1% cream.

These agents “work fast” and “improve redness quickly,” Harper, a dermatologist who practices in Birmingham, Alabama, said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference. In addition, “you’re going to know within 30 minutes or an hour whether it’s going to work or not.”

Brimonidine 0.33% gel, an alpha-2 adrenergic receptor agonist, was approved by the Food and Drug Administration (FDA) in 2014 for persistent facial erythema of rosacea. It does not treat telangiectasia and is not approved for flushing (transient erythema). Patients are advised to apply the gel daily in the morning. In phase 3 pivotal trials of patients with moderate to severe erythema of rosacea, which excluded individuals with more than two papules, a composite (investigator- and patient-reported) 2-grade improvement was seen as early as 30 minutes after application on day 1, and erythema was reduced for 9-12 hours.

Oxymetazoline 1% cream, an alpha-1a adrenergic receptor agonist, was approved by the FDA in 2017 for persistent facial erythema of rosacea. It neither treats telangiectasia nor is approved for flushing. Phase 3 trials of patients with moderate to severe persistent erythema of rosacea excluded individuals with more than three inflammatory papules or pustules. A composite (investigator- and subject-reported) 2-grade improvement was seen as early as 1 hour after application on day 1, and erythema was reduced for 9-12 hours.

 

Receptor Selectivity Differences

According to Harper, there are more reports of worsening erythema with brimonidine 0.33% gel than with oxymetazoline 1% cream, perhaps because of the different receptor selectivity between the two products. She explained that alpha-1 receptors are located only postsynaptically in vascular smooth muscle, while alpha-2 receptors are located presynaptically, which can inhibit norepinephrine and lead to vasodilation. Alpha-2 receptors are also located postsynaptically in vascular smooth muscle and in the endothelial wall, which can mediate nitric oxide release and cause vasodilation.

No head-to-head studies exist that compare brimonidine 0.33% gel with oxymetazoline 1% cream. But in a 52-week study of oxymetazoline 1% cream for persistent facial erythema associated with rosacea published in 2018, at week 52, 36.7% and 43.4% of patients achieved a 2-grade or greater composite improvement from baseline in both Clinician Erythema Assessment and Subject Self-Assessment 3 and 6 hours after a dose, respectively. Also, fewer than 1% of patients experienced a rebound effect following treatment cessation.

“What we learned from this study is that maybe patients do better if they use oxymetazoline 1% cream consistently,” Harper said. “Does that mean that everybody I give this to uses it daily? Probably not, but I think we can change the vascular tone by using it consistently every day.”

 

Oral Beta-Blockers Another Option

Alpha agonists can also help quell flushing associated with rosacea, Harper continued, but oral beta-blockers may be the better choice. In a 2020 review that drew from nine studies, researchers evaluated the use of carvedilol, propranolol, nadolol, and beta-blockers in general for rosacea-associated facial erythema and flushing. Articles studying carvedilol and propranolol showed a large reduction of erythema and flushing during treatment with a rapid onset of symptom control, while bradycardia and hypotension were the most commonly reported adverse events. “All of these agents are studied in rosacea, but none of them are FDA approved for rosacea,” Harper noted.

In a separate study, five patients with rosacea who had either severe frequent flushing episodes or persistent erythema and burning sensations were treated with carvedilol, a nonselective beta-blocker. Prior treatments included cetirizine and doxycycline, or isotretinoin combined with topical application of metronidazole gel or ivermectin without sufficient improvement in erythema. Carvedilol was added to the above treatments and titrated up to 12.5 mg twice a day and continued for at least 6 months.

The Clinician Erythema Assessment 5-point scale before therapy was 3.4 and dropped to 0.4 during therapy, while the patient self-assessment before therapy was 3.8 and dropped to 0.8 during therapy.

Another study evaluated the use of propranolol and/or doxycycline in 78 patients with rosacea. The propranolol and combination treatment groups showed more rapid improvement at weeks 4 and 8, but there was no statistically significant difference between them by week 12. Rosacea clinical scores also decreased in all groups, but there were no significant differences between them. Reduction of Assessment of Rosacea Clinical Score was 51%, 52.2%, and 57.3% in the propranolol, doxycycline, and combination groups, respectively.

Harper disclosed ties with Almirall, Cutera, Galderma, Journey, Ortho Dermatologics, and Sun Pharmaceutical Industries.

Stages I-III Screen-Detected CRC Boosts Disease-Free Survival Rates

Article Type
Changed
Wed, 11/27/2024 - 02:20

TOPLINE:

Patients with stages I-III screen-detected colorectal cancer (CRC) have better disease-free survival rates than those with non-screen–detected CRC, an effect that was independent of patient, tumor, and treatment characteristics.

METHODOLOGY:

  • Patients with screen-detected CRC have better stage-specific overall survival rates than those with non-screen–detected CRC, but the impact of screening on recurrence rates is unknown.
  • A retrospective study analyzed patients with CRC (age, 55-75 years) from the Netherlands Cancer Registry diagnosed by screening or not.
  • Screen-detected CRC were identified in patients who underwent colonoscopy after a positive fecal immunochemical test (FIT), whereas non-screen–detected CRC were those that were detected in symptomatic patients.

TAKEAWAY:

  • Researchers included 3725 patients with CRC (39.6% women), of which 1652 (44.3%) and 2073 (55.7%) patients had screen-detected and non-screen–detected CRC, respectively; CRC was distributed approximately evenly across stages I-III (35.3%, 27.1%, and 37.6%, respectively).
  • Screen-detected CRC had significantly higher 3-year rates of disease-free survival compared with non-screen–detected CRC (87.8% vs 77.2%; P < .001).
  • The improvement in disease-free survival rates for screen-detected CRC was particularly notable in stage III cases, with rates of 77.9% vs 66.7% for non-screen–detected CRC (P < .001).
  • Screen-detected CRC was more often detected at an earlier stage than non-screen–detected CRC (stage I or II: 72.4% vs 54.4%; P < .001).
  • Across all stages, detection of CRC by screening was associated with a 33% lower risk for recurrence (P < .001) independent of patient age, gender, tumor location, stage, and treatment.
  • Recurrence was the strongest predictor of overall survival across the study population (hazard ratio, 15.90; P < .001).

IN PRACTICE:

“Apart from CRC stage, mode of detection could be used to assess an individual’s risk for recurrence and survival, which may contribute to a more personalized treatment,” the authors wrote.

SOURCE:

The study, led by Sanne J.K.F. Pluimers, Department of Gastroenterology and Hepatology, Erasmus University Medical Center/Erasmus MC Cancer Institute, Rotterdam, the Netherlands, was published online in Clinical Gastroenterology and Hepatology.

LIMITATIONS:

The follow-up time was relatively short, restricting the ability to evaluate the long-term effects of screening on CRC recurrence. This study focused on recurrence solely within the FIT-based screening program, and the results were not generalizable to other screening methods. Due to Dutch privacy law, data on CRC-specific causes of death were unavailable, which may have affected the specificity of survival outcomes.

DISCLOSURES:

There was no funding source for this study. The authors declared no conflicts of interest.

Is Pancreatic Cancer Really Rising in Young People?

Article Type
Changed
Wed, 11/27/2024 - 02:17

TOPLINE:

The increase in incidence of pancreatic cancer among young Americans is largely caused by improved detection of early-stage endocrine cancer, not an increase in pancreatic adenocarcinoma. Given the stable mortality rates in this population, the increase in incidence likely reflects previously undetected cases instead of a true rise in new cases, researchers say.

METHODOLOGY:

  • Data from several registries have indicated that the incidence of pancreatic cancer among younger individuals, particularly women, is on the rise in the United States and worldwide.
  • In a new analysis, researchers wanted to see if the observed increase in pancreatic cancer incidence among young Americans represented a true rise in cancer occurrence or indicated greater diagnostic scrutiny. If pancreatic cancer incidence is really increasing, “incidence and mortality would be expected to increase concurrently, as would early- and late-stage diagnoses,” the researchers explained.
  • The researchers collected data on pancreatic cancer incidence, histology, and stage distribution for individuals aged 15-39 years from US Cancer Statistics, a database covering almost the entire US population from 2001 to 2020. Pancreatic cancer mortality data from the same timeframe came from the National Vital Statistics System.
  • The researchers looked at four histologic categories: Adenocarcinoma, the dominant pancreatic cancer histology, as well as more rare subtypes — endocrine and solid pseudopapillary — and “other” category. Researchers also categorized stage-specific incidence as early stage (in situ or localized) or late stage (regional or distant).

TAKEAWAY:

  • The incidence of pancreatic cancer increased 2.1-fold in young women (incidence, 3.3-6.9 per million) and 1.6-fold in young men (incidence, 3.9-6.2 per million) between 2001 and 2019. However, mortality rates remained stable for women (1.5 deaths per million; annual percent change [AAPC], −0.5%; 95% CI, –1.4% to 0.5%) and men (2.5 deaths per million; AAPC, –0.1%; 95% CI, –0.8% to 0.6%) over this period.
  • Looking at cancer subtypes, the increase in incidence was largely caused by early-stage endocrine cancer and solid pseudopapillary neoplasms in women, not adenocarcinoma (which remained stable over the study period).
  • Looking at cancer stage, most of the increase in incidence came from detection of smaller tumors (< 2 cm) and early-stage cancer, which rose from 0.6 to 3.7 per million in women and from 0.4 to 2.2 per million in men. The authors also found no statistically significant change in the incidence of late-stage cancer in women or men.
  • Rates of surgical treatment for pancreatic cancer increased, more than tripling among women (from 1.5 to 4.7 per million) and more than doubling among men (from 1.1 to 2.3 per million).

IN PRACTICE:

“Pancreatic cancer now can be another cancer subject to overdiagnosis: The detection of disease not destined to cause symptoms or death,” the authors concluded. “Although the observed changes in incidence are small, overdiagnosis is especially concerning for pancreatic cancer, as pancreatic surgery has substantial risk for morbidity (in particular, pancreatic fistulas) and mortality.”

SOURCE:

The study, with first author Vishal R. Patel, MD, MPH, and corresponding author H. Gilbert Welch, MD, MPH, from Brigham and Women’s Hospital, Boston, was published online on November 19 in Annals of Internal Medicine.

LIMITATIONS:

The study was limited by the lack of data on the method of cancer detection, which may have affected the interpretation of the findings.

Slim Silver Lining Appears for STI Rates

Article Type
Changed
Wed, 11/27/2024 - 03:25

The persistent epidemic of sexually transmitted infections (STIs) in the United States is showing signs of a slowdown in cases of syphilis, gonorrhea, and chlamydia, according to the latest data from the Centers for Disease Control and Prevention (CDC).

More than 2.4 million cases of these three nationally notifiable STIs were reported in the United States in 2023 but represent a 1.8% decrease from 2022, based on a new CDC report, Sexually Transmitted Infections Surveillance, 2023.

The 2023 report indicates a 7.2% decrease in gonorrhea, which accounts for most of the decrease.

Although syphilis cases increased overall, they did so by only 1% compared with double-digit increases in previous years, according to the report. Primary and secondary syphilis decreased by 10%, compared with 2022 overall, with a 13% decrease in cases among gay and bisexual men.

Congenital syphilis rates increased by 3%. However, the 3% increase represents a significant drop from the 30% increases each year in recent years, according to the report.

Chlamydia rates remained essentially stable, with a decrease of less than 1.0% overall. Reported chlamydia rates increased by 1.3% among men and decreased by 1.7% among women.

Despite the declines, overall disparities persist, with higher rates of STIs among gay and bisexual men, as well as American Indian/Alaska Native, Black/African American, and Hispanic/Latino populations, according to the report.

 

CDC Cautiously Optimistic

The CDC is “guardedly optimistic that the new data represent a turning point in terms of syphilis and gonorrhea,” said Bradley Stoner, MD, director of the CDC’s Division of STD Prevention, in an interview.

However, a tremendous amount of work remains to be done, notably in addressing disparities in care, said Stoner.

New techniques for diagnosis and treatment, such as the increased use of doxycycline (doxy PEP) for the prevention of STIs after sex for high-risk populations with a history of STIs, are likely contributing to the overall decrease, Stoner said. Other contributing factors include improved communication and awareness of STI treatment options at the community level in emergency departments, substance use facilities, and syringe use programs.

Although the United States has not yet turned the corner in reducing STIs, “We are at an inflection point in the epidemic after years of increases,” Stoner told this news organization. “The CDC is committed to keeping the momentum going and turning things around.” Although congenital syphilis rates are slowing down, it remains a significant problem with severe outcomes for mothers and infants, he noted.

The message to healthcare providers on the front lines is to increase awareness, screen widely, and provide effective treatments, Stoner emphasized.

Looking ahead, more research is needed to identify the settings in which prevention tools can be best utilized, such as urgent care or other programs, said Stoner. “My hope is that implementation science research will give us some clues.” In addition, better tools for detection and treatment of STIs are always needed, notably better diagnostics for syphilis, which still requires a blood test, although research is underway for more efficient testing.

 

Spotlight on Disparities, Syphilis

“I think these are very nuanced results,” said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, in an interview. “I am happy, on first pass, to see that STI rates have declined.” However, a closer look reveals that most of the improvements are driven by the 7% drop in gonorrhea, while chlamydia and syphilis rates are relatively stable.

The decreases may reflect that the public is receiving the messaging about the need for screening and safer sex. “Clinicians also have been educated on the need for screening,” Cennimo said. However, “we are still 90% above the [STI] rates from 20 years ago.”

Clinicians also must recognize the disparities in STI rates by race and other demographics, Cennimo said. The current report “is a call to make sure that STI and other medical services are targeted to specific groups as needed and are widely available, especially in under-resourced areas.”

“I am still dismayed by the high syphilis rates, which are also resulting in congenital syphilis,” Cennimo said. “Syphilis in pregnancy is very dangerous, and any case of congenital syphilis is a failure of preventive care and screening; it is a potentially devastating disease.

“We have good treatments for STIs, but we must continue to monitor for resistance,” said Cennimo. “More work is needed to reach high-risk individuals and to provide preventive care and screening.” 

The research was supported by the CDC. Stoner and Cennimo had no financial conflicts to disclose.

Despite the declines, overall disparities persist, with higher rates of STIs among gay and bisexual men, as well as American Indian/Alaska Native, Black/African American, and Hispanic/Latino populations, according to the report.

 

CDC Cautiously Optimistic

The CDC is “guardedly optimistic that the new data represent a turning point in terms of syphilis and gonorrhea,” said Bradley Stoner, MD, director of the CDC’s Division of STD Prevention, in an interview.

However, a tremendous amount of work remains to be done, notably in addressing disparities in care, said Stoner.

New techniques for diagnosis and treatment, such as the increased use of doxycycline (doxy PEP) for the prevention of STIs after sex for high-risk populations with a history of STIs, are likely contributing to the overall decrease, Stoner said. Other contributing factors include improved communication and awareness of STI treatment options at the community level in emergency departments, substance use facilities, and syringe use programs.

Although the United States has not yet turned the corner in reducing STIs, “We are at an inflection point in the epidemic after years of increases,” Stoner told this news organization. “The CDC is committed to keeping the momentum going and turning things around.” Although congenital syphilis rates are slowing down, it remains a significant problem with severe outcomes for mothers and infants, he noted.

The message to healthcare providers on the front lines is to increase awareness, screen widely, and provide effective treatments, Stoner emphasized.

Looking ahead, more research is needed to identify the settings in which prevention tools can be best utilized, such as urgent care or other programs, said Stoner. “My hope is that implementation science research will give us some clues.” In addition, better tools for detection and treatment of STIs are always needed, notably better diagnostics for syphilis, which still requires a blood test, although research is underway for more efficient testing.

 

Spotlight on Disparities, Syphilis

“I think these are very nuanced results,” said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, in an interview. “I am happy, on first pass, to see that STI rates have declined.” However, a closer look reveals that most of the improvements are driven by the 7% drop in gonorrhea, while chlamydia and syphilis rates are relatively stable.

The decreases may reflect that the public is receiving the messaging about the need for screening and safer sex. “Clinicians also have been educated on the need for screening,” Cennimo said. However, “we are still 90% above the [STI] rates from 20 years ago.”

Clinicians also must recognize the disparities in STI rates by race and other demographics, Cennimo said. The current report “is a call to make sure that STI and other medical services are targeted to specific groups as needed and are widely available, especially in under-resourced areas.”

“I am still dismayed by the high syphilis rates, which are also resulting in congenital syphilis,” Cennimo said. “Syphilis in pregnancy is very dangerous, and any case of congenital syphilis is a failure of preventive care and screening; it is a potentially devastating disease.

“We have good treatments for STIs, but we must continue to monitor for resistance,” said Cennimo. “More work is needed to reach high-risk individuals and to provide preventive care and screening.” 

The research was supported by the CDC. Stoner and Cennimo had no financial conflicts to disclose.
