Groundbreaking new regimen for advanced Hodgkin lymphoma
“[SWOG] S1826, the largest Hodgkin lymphoma study in National Clinical Trials Network history, is a key step toward harmonizing the pediatric and adult treatment of advanced-stage Hodgkin lymphoma,” the authors reported in late-breaking research presented at the annual meeting of the American Society of Clinical Oncology.
“Based on the magnitude of the benefit and with nivolumab being better tolerated than brentuximab, we anticipate that these results will be practice changing and nivolumab [and chemotherapy] will become a new standard of care,” lead author Alex Francisco Herrera, MD, an associate professor and chief of the division of lymphoma in the department of hematology and hematopoietic cell transplantation, City of Hope Medical Center, Duarte, Calif., said in an interview.
The randomized SWOG S1826 trial of 976 patients with newly diagnosed stage 3 or 4 Hodgkin lymphoma included patients ranging in age from as young as 12 to 83 years, and at a median follow-up of 12.1 months, the addition of nivolumab to the chemotherapy regimen of doxorubicin, vinblastine, and dacarbazine (AVD) was associated with as much as a 52% reduction in the risk of disease-related death, compared with the addition of brentuximab.
The results are especially important considering that Hodgkin lymphoma disproportionately affects younger patients, including those in their teens, 20s, and 30s, Dr. Herrera noted in an interview.
“We found that treatment with nivolumab reduced the risk of progression by half, and, importantly, the benefit was observed across subgroups,” he said.
Relapse/refractory disease common in advanced HL
In general, outcomes are relatively good even for stage III or IV Hodgkin lymphoma; however, about a quarter of patients still have relapses or refractory disease.
While the introduction of novel frontline treatment with brentuximab-AVD was important in improving overall survival, the regimen adds toxicity, particularly among older patients, and many pediatric patients receiving the therapy still require radiation therapy, with its undesirable side effects.
Meanwhile, the progressive death 1 inhibitor nivolumab, approved by the Food and Drug Administration, gained interest as a potentially ideal alternative in light of Hodgkin lymphoma’s status basically as “the poster child for PD-1 blockade,” Dr. Herrera said.
“There are genetic changes in the Hodgkin lymphoma tumor cell that lead to expression of PD-1 ligands on the surface of Hodgkin lymphoma cells, and when we use a drug like nivolumab, we see that even patients with the most treatment-resistant rates of lymphoma have as much as a 70% response rate,” he explained in a press briefing.
To further investigate, the first-of-its-kind collaboration of adult and pediatric cancer teams conducted the S1826 trial to evaluate the treatment across age groups with stage 3 and 4 Hodgkin lymphoma.
For the study, conducted between July 2019 and October 2022, 976 patients were randomized to treatment either with nivolumab (n = 489) or brentuximab (n = 487), each in combination with the AVD regimen.
Of the patients, the median age was 27, with 24% under the age of 18, 10% over 60 and 32% with IPS 4-7. Among them, 56% were male and 76% were White.
For the primary endpoint, at a median follow-up of 12.1 months, the rate of progression-free survival was significantly higher in the nivolumab arm (hazard ratio, 0.48; one-sided P = .0005), with the rate of 1-year survival at 94% in the nivolumab group versus 86% in the brentuximab group, for a 52% reduction in the risk of disease-related death with nivolumab versus brentuximab.
A total of 11 deaths occurred in the brentuximab group, 7 of which were related to adverse events, compared with 4 deaths in the nivolumab group, 3 of which were related to nivolumab.
Importantly, fewer than 1% of patients with nivolumab required radiation therapy.
“That’s a dramatic reduction of the proportion of the very youngest patients receiving radiotherapy,” Dr. Herrera noted.
Grade 3 or higher hematologic adverse events were higher in the nivolumab group, at 48.4%, including 45.1% that were grade 3 or higher neutropenia, compared with 30.5% with brentuximab, including 23.9% with grade 3 or higher neutropenia.
However, rates of any grade of febrile neutropenia were similar with nivolumab and brentuximab (5.6% vs. 6.4%, respectively), as were rates of pneumonitis (2.0% vs. 3.2%), ALT elevation (30.7% vs. 39.8%), and colitis (1% vs. 1.3%).
In addition, rates of hypo- and hyperthyroidism were more frequent after nivolumab (7% and 3% with nivolumab, respectively, vs. fewer than 1% with brentuximab).
But, of note, peripheral neuropathy of any grade was more common after brentuximab (sensory: 28.1% nivolumab vs. 54.2% brentuximab; motor: 4% nivolumab vs. 6.8% brentuximab).
“I can’t emphasize how important neuropathy is as a side effect in these young patients who have the rest of their life ahead of them,” Dr. Herrera explained. “It’s fantastic to be cured of cancer, but tough to not be able to feel your fingers and toes.”
With its broad inclusion of age groups and a diverse population, he added that the study was importantly a “representative” trial, reflecting a “real-world population.”
“Incredibly, a quarter of patients were under the age of 18; 10% were over the age of 60, a quarter of patients were Hispanic and Black, and in fact we had a quite good representation of higher-risk subgroups,” he said.
Looking forward, longer-term follow-up from this study will be important in determining if the improvement observed in disease-related deaths is maintained over time, Dr. Herrera noted.
“Additionally, it is crucial to obtain data on other key outcomes such as overall survival and quality of life from longer-term follow of this study,” he said.
‘A huge step forward’
Commenting on the study, Oreofe Odejide, MD, a medical oncologist at the Dana-Farber Cancer Institute and an assistant professor of medicine at Harvard Medical School, both in Boston, said that results were unprecedented.
“Although a majority of patients with advanced stage Hodgkin lymphoma will be cured with initial therapy, about 20% of patients still end up with relapsed or refractory disease,” she said in an interview. “Therefore, the findings from this study represent a huge step forward in the management of advanced Hodgkin lymphoma in children and adults, leading to an improved and well-tolerated standard of care.”
Dr. Odejide agreed that the findings are potentially practice changing.
“Brentuximab-AVD set a high bar for the treatment of advanced-stage Hodgkin lymphoma, as it was the first regimen to show a meaningful improvement in disease-related death compared to ABVD chemotherapy in several years,” she explained.
“The fact that the SWOG1826 trial now shows a significant benefit of nivolumab-AVD over brentuximab and included both pediatric and adult patients unlike prior studies, is highly compelling,” Dr. Odejide added. “This has strong potential to change the standard of care for patients with previously untreated, advanced-stage Hodgkin lymphoma.”
The study received funding from the National Cancer Institute and from Bristol-Myers Squibb. Dr. Herrera reported relationships with Abbvie, ADC Therapeutics, Adicet Bio, AstraZeneca/MedImmune, Bristol-Myers Squibb, Caribou Biosciences, Genentech/Roche, Genmab, Karyopharm Therapeutics, Merck, Pfizer, Regeneron, Seagen, Takeda, and Tubulis Gmbh. Dr. Odejide reported no disclosures.

FROM ASCO 2023
Flavanol supplement improves memory in adults with poor diets
Taking a daily flavanol supplement improves hippocampal-dependent memory in older adults who have a relatively poor diet, results of a large new study suggest.
There’s increasing evidence that certain nutrients are important for the aging body and brain, study investigator Scott Small, MD, the Boris and Rose Katz Professor of Neurology, Columbia University Vagelos College of Physicians and Surgeons, New York, told this news organization.
“With this new study, I think we can begin to say flavanols might be the first one that really is a nutrient for the aging brain.”
These findings, said Dr. Small, represent “the beginning of a new era” that will eventually lead to formal recommendations” related to ideal intake of flavanols to reduce cognitive aging.
The findings were published online in the Proceedings of the National Academy of Science.
Better cognitive aging
Cognitive aging refers to the decline in cognitive abilities that are not thought to be caused by neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. Cognitive aging targets two areas of the brain: the hippocampus, which is related to memory function, and the prefrontal cortex, which is related to attention and executive function.
Previous research has linked flavanols, which are found in foods like apples, pears, berries, and cocoa beans, to improved cognitive aging. The evidence shows that consuming these nutrients might be associated with the hippocampal-dependent memory component of cognitive aging.
The new study, known as COcoa Supplement and Multivitamin Outcomes Study-Web (COSMOS-Web), included 3,562 generally healthy men and women, mean age 71 years, who were mostly well-educated and non-Hispanic/non-Latinx White individuals.
Participants were randomly assigned to receive oral flavanol-containing cocoa extract (500 mg of cocoa flavanols, including 80 mg of epicatechin) or a placebo daily.
The primary endpoint was hippocampal-dependent memory at year 1 as assessed with the ModRey, a neuropsychological test designed to measure hippocampal function.
Results showed participants in both groups had a typical learning (practice) effect, with similar improvements (d = 0.025; P = .42).
Researchers used other tests to measure cognition: the Color/Directional Flanker Task, a measure of prefrontal cortex function, and the ModBent, a measure that’s sensitive to dentate gyrus function. The flavanol intervention did not affect ModBent results or performance on the Flanker test after 1 year.
However, it was a different story for those with a poor diet at baseline. Researchers stratified participants into tertiles on the basis of diet quality as measured by the Healthy Eating Index (HEI) scores. Those in the lowest tertile had poorer baseline hippocampal-dependent memory performance but not memory related to the prefrontal cortex.
The flavanol intervention improved performance on the ModRey test, compared with placebo in participants in the low HEI tertile (overall effect: d = 0.086; P = .011) but not among those with a medium or high HEI at baseline.
“We confirmed that the flavanol intervention only benefits people who are relatively deficient at baseline,” said Dr. Small.
The correlation with hippocampal-dependent memory was confirmed in a subset of 1,361 study participants who provided a urine sample. Researchers measured urinary 5-(3′,4′-dihydroxyphenyl)-gamma-valerolactone metabolite (gVLM) concentrations, a validated biomarker of flavanol consumption.
After stratifying these results into tertiles, researchers found performance on the ModRey was significantly improved with the dietary flavanol intervention (overall effect: d = 0.141; P = .006) in the lowest gVLM tertile.
Memory restored
When participants in the lowest tertile consumed the supplement, “their flavanol levels went back to normal, and when that happened, their memory was restored,” said Dr. Small.
It appears that there is a sort of ceiling effect to the flavanol benefits. “It seems what you need to do is normalize your flavanol levels; if you go above normal, there was no evidence that your memory keeps on getting better,” said Dr. Small.
The study included only older adults, so it’s unclear what the impact of flavanol supplementation is in younger adults. But cognitive aging “begins its slippery side” in the 40s, said Dr. Small. “If this is truly a nutrient that is taken to prevent that slide from happening, it might be beneficial to start in our 40s.”
He recognized that the effect size is not large but said this is “very dependent” on baseline factors and most study participants had a rather healthy diet. “None of our participants were really highly deficient” in flavanols, he said.
“To see a stronger effect size, we need to do another study where we recruit people who are very low, truly deficient, in flavanols, and then see what happens.”
Showing that flavanols are linked to the hippocampal and not to the prefrontal component of cognitive aging “speaks to the mechanism,” said Dr. Small.
Though the exact mechanism linking flavanols with enhanced memory isn’t clear, there are some clues; for example, research suggests cognitive aging affects the dentate gyrus, a subregion of the hippocampus.
The flavanol supplements were well tolerated. “I can say with close to certainty that this is very safe,” said Dr. Small, adding the flavanols have now been used in numerous studies.
The findings suggest flavanol consumption might be part of future dietary guidelines. “I suspect that once there is sufficient evidence, flavanols will be part of the dietary recommendations for healthy aging,” said Dr. Small.
A word of caution
Heather M. Snyder, PhD, vice president of medical and scientific relations, Alzheimer’s Association, said that though science suggests a balanced diet is good for overall brain health, no single food, beverage, ingredient, vitamin, or supplement has yet been proven to prevent dementia, treat or cure Alzheimer’s, or benefit cognitive function or brain health.
Experts agree the best source of vitamins and other nutrients is from whole foods as part of a balanced diet. “We recognize that, for a variety of reasons, this may not always be possible,” said Dr. Snyder.
However, she noted, dietary supplements are not subject to the same rigorous review and regulation process as medications.
“The Alzheimer’s Association strongly encourages individuals to have conversations with their physicians about all medications and dietary supplements they are currently taking or interested in starting.”
COSMOS is supported by an investigator-initiated grant from Mars Edge, a segment of Mars, company engaged in flavanol research and flavanol-related commercial activities, which included infrastructure support and the donation of study pills and packaging. Small reports receiving an unrestricted research grant from Mars.

Showing that flavanols are linked to the hippocampal and not to the prefrontal component of cognitive aging “speaks to the mechanism,” said Dr. Small.
Though the exact mechanism linking flavanols with enhanced memory isn’t clear, there are some clues; for example, research suggests cognitive aging affects the dentate gyrus, a subregion of the hippocampus.
The flavanol supplements were well tolerated. “I can say with close to certainty that this is very safe,” said Dr. Small, adding the flavanols have now been used in numerous studies.
The findings suggest flavanol consumption might be part of future dietary guidelines. “I suspect that once there is sufficient evidence, flavanols will be part of the dietary recommendations for healthy aging,” said Dr. Small.
A word of caution
Heather M. Snyder, PhD, vice president of medical and scientific relations, Alzheimer’s Association, said that though science suggests a balanced diet is good for overall brain health, no single food, beverage, ingredient, vitamin, or supplement has yet been proven to prevent dementia, treat or cure Alzheimer’s, or benefit cognitive function or brain health.
Experts agree the best source of vitamins and other nutrients is from whole foods as part of a balanced diet. “We recognize that, for a variety of reasons, this may not always be possible,” said Dr. Snyder.
However, she noted, dietary supplements are not subject to the same rigorous review and regulation process as medications.
“The Alzheimer’s Association strongly encourages individuals to have conversations with their physicians about all medications and dietary supplements they are currently taking or interested in starting.”

Taking a daily flavanol supplement improves hippocampal-dependent memory in older adults who have a relatively poor diet, results of a large new study suggest.
There’s increasing evidence that certain nutrients are important for the aging body and brain, study investigator Scott Small, MD, the Boris and Rose Katz Professor of Neurology, Columbia University Vagelos College of Physicians and Surgeons, New York, told this news organization.
“With this new study, I think we can begin to say flavanols might be the first one that really is a nutrient for the aging brain.”
These findings, said Dr. Small, represent “the beginning of a new era” that will eventually lead to formal recommendations” related to ideal intake of flavanols to reduce cognitive aging.
The findings were published online in the Proceedings of the National Academy of Science.
Better cognitive aging
Cognitive aging refers to the decline in cognitive abilities that are not thought to be caused by neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. Cognitive aging targets two areas of the brain: the hippocampus, which is related to memory function, and the prefrontal cortex, which is related to attention and executive function.
Previous research has linked flavanols, which are found in foods like apples, pears, berries, and cocoa beans, to improved cognitive aging. The evidence shows that consuming these nutrients might be associated with the hippocampal-dependent memory component of cognitive aging.
The new study, known as COcoa Supplement and Multivitamin Outcomes Study-Web (COSMOS-Web), included 3,562 generally healthy men and women, mean age 71 years, who were mostly well-educated and non-Hispanic/non-Latinx White individuals.
Participants were randomly assigned to receive oral flavanol-containing cocoa extract (500 mg of cocoa flavanols, including 80 mg of epicatechin) or a placebo daily.
The primary endpoint was hippocampal-dependent memory at year 1 as assessed with the ModRey, a neuropsychological test designed to measure hippocampal function.
Results showed participants in both groups had a typical learning (practice) effect, with similar improvements (d = 0.025; P = .42).
Researchers used other tests to measure cognition: the Color/Directional Flanker Task, a measure of prefrontal cortex function, and the ModBent, a measure that’s sensitive to dentate gyrus function. The flavanol intervention did not affect ModBent results or performance on the Flanker test after 1 year.
However, it was a different story for those with a poor diet at baseline. Researchers stratified participants into tertiles on the basis of diet quality as measured by the Healthy Eating Index (HEI) scores. Those in the lowest tertile had poorer baseline hippocampal-dependent memory performance but not memory related to the prefrontal cortex.
The flavanol intervention improved performance on the ModRey test, compared with placebo in participants in the low HEI tertile (overall effect: d = 0.086; P = .011) but not among those with a medium or high HEI at baseline.
“We confirmed that the flavanol intervention only benefits people who are relatively deficient at baseline,” said Dr. Small.
The correlation with hippocampal-dependent memory was confirmed in a subset of 1,361 study participants who provided a urine sample. Researchers measured urinary 5-(3′,4′-dihydroxyphenyl)-gamma-valerolactone metabolite (gVLM) concentrations, a validated biomarker of flavanol consumption.
After stratifying these results into tertiles, researchers found performance on the ModRey was significantly improved with the dietary flavanol intervention (overall effect: d = 0.141; P = .006) in the lowest gVLM tertile.
Memory restored
When participants in the lowest tertile consumed the supplement, “their flavanol levels went back to normal, and when that happened, their memory was restored,” said Dr. Small.
It appears that there is a sort of ceiling effect to the flavanol benefits. “It seems what you need to do is normalize your flavanol levels; if you go above normal, there was no evidence that your memory keeps on getting better,” said Dr. Small.
The study included only older adults, so it’s unclear what the impact of flavanol supplementation is in younger adults. But cognitive aging “begins its slippery side” in the 40s, said Dr. Small. “If this is truly a nutrient that is taken to prevent that slide from happening, it might be beneficial to start in our 40s.”
He recognized that the effect size is not large but said this is “very dependent” on baseline factors and most study participants had a rather healthy diet. “None of our participants were really highly deficient” in flavanols, he said.
“To see a stronger effect size, we need to do another study where we recruit people who are very low, truly deficient, in flavanols, and then see what happens.”

New guideline weighs medication options for chronic constipation
The guideline, published simultaneously in the American Journal of Gastroenterology and in Gastroenterology, was developed jointly by the American Gastroenterological Association and the American College of Gastroenterology. It marks the AGA’s first update on chronic idiopathic constipation (CIC), also called functional constipation, in a decade.
In an interview, guideline lead author Lin Chang, MD, of the University of California, Los Angeles, noted that CIC – defined as constipation lasting at least 3 months in the absence of malignancy or obstruction, a medication side effect, or inflammatory bowel disease – is common, affecting between 8% and 12% of all U.S. adults. Most will be treated by primary care physicians, not specialists, Dr. Chang said. And most will see their physicians having already tried different over-the-counter treatments.
“The criteria for CIC or functional constipation hasn’t really changed” since the last AGA guideline on it was published in 2013, Dr. Chang said, adding that the diagnostic standard currently used is the Rome IV criteria for functional constipation. “There are just more medications right now than there were 10 years ago.”
The new guideline, into which evidence from 28 studies was integrated, offers recommendations regarding different types of fiber; the osmotic laxatives polyethylene glycol, magnesium oxide, and lactulose; and the stimulant laxatives bisacodyl, sodium picosulfate, and senna. It also assesses the secretagogues lubiprostone, linaclotide, plecanatide, and the serotonin type 4 agonist prucalopride.
One commonly used agent in clinical practice, the stool softener docusate sodium, does not appear in the guideline, as there was too little data available on it to make an assessment, Dr. Chang said. Fruit-based laxatives were excluded because they were the subject of a recent evidence review. Lifestyle modifications such as exercise, surgical interventions, and probiotics were not assessed.
The guideline’s strongest recommendations are for polyethylene glycol, sodium picosulfate, linaclotide, plecanatide, and prucalopride, with conditional recommendations for fiber, lactulose, senna, magnesium oxide, and lubiprostone.
As costs of the recommended therapies vary from less than $10 a month to over $500, the authors also included price information, noting that “patient values, costs, and health equity considerations” must be factored into treatment choices. “For polyethylene glycol there’s a strong recommendation, although the certainty of evidence was moderate,” Dr. Chang said. “And with fiber, even though we made only a conditional recommendation based on the evidence, our remarks and our algorithm make clear that it should be considered as a first-line treatment.”
In general, “if someone has more mild symptoms, you should try fiber or increase their fiber intake in their diet,” Dr. Chang commented. “If that doesn’t work, try over-the-counter remedies like polyethylene glycol. Then if symptoms are more severe, or if they fail the first-line treatments, then you go to prescription agents.”
In clinical practice, “there always considerations besides scientific evidence of safety and efficacy,” Dr. Chang stressed. “You have to personalize treatment for the patient.” A patient may present having already failed with fiber, or who does not want to use magnesium or can’t afford a costlier agent.
The guidelines contain implementation advice that might guide choice of therapy or dosing. With the prescription osmotic laxative lactulose, for example, “you may not wish to use it as a first-line treatment because bloating and flatulence are very common,” Dr. Chang said. “Our implementation advice makes that clear.” For senna, a stimulant laxative derived from the leaves of the senna plant and for which quality evidence is limited, the guideline authors stressed that patients should be started on low doses to avoid cramping.
Dr. Chang said that, while the new guideline covers medication options for otherwise-healthy adults, clinicians should be mindful that patients presenting with CIC might still have a defecatory disorder. “A person could also have pelvic floor dysfunction as a primary cause or contributing factor. If someone fails fiber or polyethylene glycol, consider a digital rectal examination as part of the physical exam. If this is abnormal, consider referring them for anorectal manometry.”
Untreated constipation carries risks, Dr. Chang noted, but “sometimes people with bothersome symptoms don’t treat them because they’re worried they’ll become dependent on treatment. It’s a dependency in the sense that you have to treat any chronic condition, such as high blood pressure or diabetes, but the treatments aren’t addictive, except for some stimulant laxatives to which people can develop tolerance.”
Hemorrhoids and defecatory disorders can occur over time because of straining, Dr. Chang said. “The pelvic wall can also get very lax, and that is hard to fix. Or, one can develop a rectal prolapse. Another thing that happens when people have longstanding constipation for many years is they start losing the urge to have a bowel movement.”

The guideline’s development was funded by the AGA and ACG, without industry support. Authors with conflicts of interest regarding a specific intervention or drug were not allowed to weigh in on those interventions.

FDA warns people to avoid compounded semaglutide medicines
Compounded medicines are not FDA approved but are allowed to be made during an official drug shortage. Ozempic and Wegovy are currently on the FDA’s shortage list, but the federal agency warned that it has received reports of people experiencing “adverse events” after using compounded versions of the drugs. (The FDA did not provide details of those events or where the drugs involved were compounded.)
Agency officials are concerned that the compounded versions may contain ingredients that sound like the brand name drugs’ active ingredient, semaglutide, but are different because the ingredients are in salt form.
“Patients should be aware that some products sold as ‘semaglutide’ may not contain the same active ingredient as FDA-approved semaglutide products and may be the salt formulations,” the FDA warning stated. “Products containing these salts, such as semaglutide sodium and semaglutide acetate, have not been shown to be safe and effective.”
The agency said salt forms don’t meet the criteria for compounding during a shortage and sent a letter to the National Association of Boards of Pharmacy expressing “concerns with use of the salt forms in compounded products.”
Patients and health care providers should be aware that “compounded drugs are not FDA approved, and the agency does not verify the safety or effectiveness of compounded drugs,” the FDA explained in its statement.
The Alliance for Pharmacy Compounding’s board of directors said in a statement that some compounders’ arguments for the suitability of semaglutide sodium are “worthy of discussion,” but the board did not endorse those arguments.
For people who use an online pharmacy, the FDA recommends checking the FDA’s website BeSafeRx to check its credentials.

Low-dose atropine improves myopia in children
Myopia affects roughly one-third of the population worldwide - a figure that is projected to reach 50% by 2050. Low-dose atropine, which helps curb the condition, currently is available in the United States only through compounding pharmacies. The products contain preservatives – raising questions about potential toxicities to the eye – and may not be of pharmaceutical grade. In a new study published in JAMA Ophthalmology,
Methodology
- The CHAMP study was a double-masked, placebo-controlled, randomized, phase 3 trial conducted between Nov. 20, 2017, and Aug. 22, 2022, that involved children at 26 sites in North America and 5 centers in Europe.
- Children received either 0.01% or 0.02% atropine drops once per day.
- Patients were aged 3-16 years. They demonstrated a spherical equivalent refractive error (SER) of −0.50 diopter (D) to −6.00 D astigmatism no worse than −1.50 D.
- Of these patients, 573 were included in a safety analysis, and 489 were included in a modified intention-to-treat analysis.
Takeaways
- After 36 months, the 0.01% dose of atropine was associated with a significantly lower responder proportion (odds ratio, 4.54) and slower progression of SER and axial elongation.
- The effect of the 0.02% dose on responder proportion and SER progression was not statistically significant, but the treatment was associated with slower axial elongation.
- The researchers observed no serious ocular adverse events and few serious nonocular events, none of which was determined to be associated with the treatment.
In practice: According to the researchers, “from a risk/benefit perspective, the efficacy and safety observed suggests that low-dose atropine may provide a treatment option for children aged 3-17 years with myopia progression, which may lead to less frequent or delayed change in glasses, progression to less severe correction, and potentially reduce long-term sequelae, which could lead to vision loss later in life, such as myopic maculopathy.”
Study details: The CHAMP study was led by Karla Zadnik, OD, PhD, of Ohio State University, Columbus, and was funded by Vylulma.
Limitations: The researchers said the trial was potentially limited by the fact that patients switched from the study drug to confounding treatments. In addition, patients at the low and high age ranges were not well represented.
Disclosures: Dr. Zadnik received consultant fees from Vyluma during the study.

- The researchers observed no serious ocular adverse events and few serious nonocular events, none of which was determined to be associated with the treatment.
In practice: According to the researchers, “from a risk/benefit perspective, the efficacy and safety observed suggests that low-dose atropine may provide a treatment option for children aged 3-17 years with myopia progression, which may lead to less frequent or delayed change in glasses, progression to less severe correction, and potentially reduce long-term sequelae, which could lead to vision loss later in life, such as myopic maculopathy.”
Study details: The CHAMP study was led by Karla Zadnik, OD, PhD, of Ohio State University, Columbus, and was funded by Vylulma.
Limitations: The researchers said the trial was potentially limited by the fact that patients switched from the study drug to confounding treatments. In addition, patients at the low and high age ranges were not well represented.
Disclosures: Dr. Zadnik received consultant fees from Vyluma during the study.

Preventive antipyretics, antibiotics not needed in stroke
“The results of PRECIOUS do not support preventive use of antiemetic, antipyretic, or antibiotic drugs in older patients with acute stroke,” senior study author Bart van der Worp, MD, professor of acute neurology at University Medical Center, Utrecht, the Netherlands, concluded.
“This trial was all about prevention,” trial co-investigator, Philip Bath, MD, professor of stroke medicine at the University of Nottingham (England), said in an interview.
“It was trying to improve outcomes by preventing infection, fever, and aspiration pneumonia, but the message from these results is that while we should be on the lookout for these complications and treat them early when they occur, we don’t need to give these medications on a prophylactic basis.”
The PREvention of Complications to Improve OUtcome in elderly patients with acute Stroke (PRECIOUS) trial was presented at the annual European Stroke Organisation Conference, held in Munich.
Dr. Van der Worp explained that infections, fever, and aspiration pneumonia frequently occur following stroke, particularly in older patients, and these poststroke complications are associated with an increased risk of death and poor functional outcome.
“We assessed whether a pharmacological strategy to reduce the risk of infections and fever improves outcomes of elderly patients with moderately severe or severe stroke,” he said.
Previous studies looking at this approach have been performed in broad populations of stroke patients who had a relatively low risk of poststroke complications, thereby reducing the potential for benefit from these interventions.
The current PRECIOUS trial was therefore conducted in a more selective elderly population with more severe strokes, a group believed to be at higher risk of infection and fever.
The trial included patients aged 66 years or older with moderately severe to severe ischemic stroke (National Institutes of Health Stroke Scale score ≥ 6) or intracerebral hemorrhage.
They were randomized in a 3 x 2 factorial design to oral, rectal, or intravenous metoclopramide (10 mg three times a day); intravenous ceftriaxone (2,000 mg once daily); oral, rectal, or intravenous paracetamol (1,000 mg four times daily); or usual care.
Medications were started within 24 hours after symptom onset and continued for 4 days or until complete recovery or discharge from hospital, if earlier.
“We assessed these three simple, safe, and inexpensive therapies – paracetamol to prevent fever; the antiemetic, metoclopramide, to prevent aspiration; and ceftriaxone, which is the preferred antibiotic for post-stroke pneumonia in the Netherlands,” Dr. van der Worp said.
The primary outcome was modified Rankin Scale (mRS) score at 90 days.
The trial was aiming to enroll 3,800 patients from 67 European sites but was stopped after 1,493 patients had been included because of lack of funding. After excluding patients who withdrew consent or were lost to follow-up, 1,471 patients were included in the intention-to-treat analysis.
Results showed no effect on the primary outcome of any of the prophylactic treatments.
“None of the medications had any effect on the functional outcome at 90 days. This was a surprise to me,” Dr. Van der Worp commented. “I had expected that at least one of the medications would have been of benefit.”
A secondary outcome was the diagnosis of pneumonia, which again was not reduced by any of the medications.
“Remarkably, neither ceftriaxone nor metoclopramide had any effect on the risk of developing pneumonia. It was all quite disappointing,” van der Worp said.
There was, however, a reduction in the incidence of urinary tract infections in the ceftriaxone group.
Trying to explain why there was a reduction in urinary tract infections but not pneumonia with the antibiotic, Dr. Van der Worp pointed out that poststroke pneumonia is to a large extent caused by a mechanical process (aspiration), and bacteria may only play a minor role in its development.
He said he was therefore surprised that metoclopramide, which should prevent the mechanical process of aspiration, did not reduce the development of pneumonia.
He suggested that some patients may have already experienced aspiration before the metoclopramide was started, noting that many patients with acute stroke already have signs of pneumonia on CT scan in the first few hours after symptom onset.
A previous smaller study (MAPS) had shown a lower rate of pneumonia in stroke patients given metoclopramide, but in this study the drug was given for 3 weeks.
Discussing the PRECIOUS trial at the ESOC meeting, Christine Roffe, MD, professor of stroke medicine at Keele (England) University, and senior investigator of the MAPS study, suggested that a longer period of metoclopramide treatment may be needed than the 4 days given in the PRECIOUS study, as the risk of pneumonia persists for longer than just a few days.
She noted that another trial (MAPS-2) is now underway in the United Kingdom to try and confirm the first MAPS result with longer duration metoclopramide.
Dr. Van der Worp responded: “Certainly, I think that the MAPS-2 study should be continued. It is investigating a much longer duration of treatment, which may be beneficial, especially in patients with more severe strokes.”
On the reason for the disappointing results with paracetamol, Dr. Van der Worp elaborated: “We found that only a very few of these older patients developed a fever – only about 5% in the control group. Paracetamol did reduce the risk of fever, but because the proportion of patients who developed fever was so small, this may have been why it didn’t translate into any effect on the functional outcome.”
Dr. Roffe concluded that PRECIOUS was an important study. “There is also a positive message here. We have all been worried about using too many antibiotics. We need to make sure we use these drugs responsibly. I think this trial has told us there is little point in using antibiotics in a preventative way in these patients.”
She added that although the trial was stopped prematurely, it had produced decisive results.
“Yes, I believe that even if the trial was much larger, we still would not have shown an effect,” Dr. Van der Worp agreed.

Positive top-line results for cannabinoid-based med for nerve pain
, new top-line results released by Zelira Therapeutics suggest.
“The implications of these results for patients are incredibly promising,” principal investigator Bryan Doner, DO, medical director of HealthyWays Integrated Wellness Solutions, Gibsonia, Pa., said in a news release.
“Through this rigorously designed study, we have demonstrated that ZLT-L-007 is a safe, effective, and well-tolerated alternative for patients who would typically seek a Lyrica-level of pain relief,” he added.
The observational, nonblinded trial tested the efficacy, safety, and tolerability of ZLT-L-007 against pregabalin in 60 adults with diabetic nerve pain.
The study had three groups with 20 patients each (pregabalin alone, pregabalin plus ZLT-L-007, and ZLT-L-007 alone).
Top-line results show the study met its primary endpoint for change in daily pain severity as measured by the percent change from baseline at 30, 60, and 90 days on the Numerical Rating Scale.
For the pregabalin-only group, there was a reduction in symptom severity at all follow-up points, ranging from 20% to 35% (median percent change from baseline), the company said.
For the ZLT-L-007 only group, there was about a 33% reduction in symptom severity at 30 days, and 71% and 78% reduction, respectively, at 60 and 90 days, suggesting a larger improvement in symptom severity than with pregabalin alone, the company said.
For the pregabalin plus ZLT-L-007 group, there was a moderate 20% reduction in symptom severity at 30 days, but a larger reduction at 60 and 90 days (50% and 72%, respectively), which indicates substantially greater improvement in symptom severity than with pregabalin alone, the company said.
The study also met secondary endpoints, including significant decreases in daily pain severity as measured by the Visual Analog Scale and measurable changes in the short-form McGill Pain Questionnaire and Neuropathic Pain Symptom Inventory.
Dr. Doner noted that the top-line data showed “no serious adverse events, and participants’ blood pressure and other safety vitals remained unaffected throughout. This confirms that ZLT-L-007 is a well-tolerated product that delivers statistically significant pain relief, surpassing the levels achieved by Lyrica.”
The company plans to report additional insights from the full study, as they become available, during fiscal year 2023-2024.

FDA approves new drug, sotagliflozin, for heart failure
Sotagliflozin, a novel agent that inhibits sodium-glucose cotransporter 1 as well as SGLT2, has received marketing approval from the Food and Drug Administration for reducing the risk for cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in patients with heart failure, and also for preventing these same events in patients with type 2 diabetes, chronic kidney disease (CKD), and other cardiovascular disease risk factors.
This puts sotagliflozin in direct competition with two SGLT2 inhibitors, dapagliflozin (Farxiga) and empagliflozin (Jardiance), that already have indications for preventing heart failure hospitalizations in patients with heart failure as well as approvals for type 2 diabetes and preservation of renal function.
Officials at Lexicon Pharmaceuticals, the company that developed and will market sotagliflozin under the trade name Inpefa, said in a press release that they expect U.S. sales of the agent to begin before the end of June 2023. The release also highlighted that the approval broadly covered use in patients with heart failure across the full range of both reduced and preserved left ventricular ejection fractions.
They base this niche target for sotagliflozin on results from the SOLOIST-WHF trial, which randomized 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure and showed a significant 33% reduction in the rate of deaths from cardiovascular causes and hospitalizations and urgent visits for heart failure, compared with control patients during a median 9 months of follow-up. Nearly half of the enrolled patients received their first dose while still hospitalized, while the other half received their first dose a median of 2 days after hospital discharge. The drug appeared safe.
Cutting heart failure rehospitalizations in half
An exploratory post hoc analysis of SOLOIST-WHF showed that treatment with sotagliflozin cut the rate of rehospitalizations roughly in half after both 30 and 90 days compared with control patients, according to an abstract presented at the 2022 annual scientific sessions of the AHA that has not yet been published in a peer-reviewed journal.
The only SGLT2 inhibitor tested so far when initiated in patients during hospitalization for heart failure is empagliflozin, in the EMPULSE trial, which randomized 530 patients. EMPULSE also showed that starting an SGLT2 inhibitor in this setting was safe and resulted in significant clinical benefit, the study’s primary endpoint, defined as a composite of death from any cause, number of heart failure events, and time to first heart failure event, or a 5-point or greater difference in change from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score at 90 days.
In the DELIVER trial, which tested dapagliflozin in patients with heart failure with preserved ejection fraction, roughly 10% of patients started study treatment during or within 30 days of heart failure hospitalization, and in this subgroup, dapagliflozin appeared as effective as it was in the other 90% of patients who did not start the drug during an acute or subacute phase.
Despite the SOLOIST-WHF evidence for sotagliflozin’s safety and efficacy in this economically important clinical setting, some experts say the drug faces an uphill path as it contends for market share against two solidly established, albeit dramatically underused, SGLT2 inhibitors. (Recent data document that 20% or fewer of U.S. patients eligible for treatment with an SGLT2 inhibitor receive it, such as a review of 49,000 patients hospitalized during 2021-2022 with heart failure with reduced ejection fraction.)
Others foresee a clear role for sotagliflozin, particularly because of additional facets of the drug’s performance in trials that they perceive give it an edge over dapagliflozin and empagliflozin. This includes evidence that sotagliflozin treatment uniquely (within the SGLT2 inhibitor class) cuts the rate of strokes and myocardial infarctions, as well as evidence of its apparent ability to lower hemoglobin A1c levels in patients with type 2 diabetes and with an estimated glomerular filtration rate below 30 mL/min per 1.73 m2, a property likely linked to inhibition of SGLT1 in the gut that dampens intestinal glucose absorption.
Sotagliflozin uptake ‘will be a challenge’
“It will be a challenge” for sotagliflozin uptake, given the head start that both dapagliflozin and empagliflozin have had as well-documented agents for patients with heart failure, commented Javed Butler, MD, a heart failure clinician and trialist who is president of the Baylor Scott & White Research Institute in Dallas.
Given the position dapagliflozin and empagliflozin currently have in U.S. heart failure management – with the SGLT2 inhibitor class called out in guidelines as foundational for treating patients with heart failure with reduced ejection fraction and likely soon for heart failure with preserved ejection fraction as well – “I can’t imagine [sotagliflozin] will be considered a preferred option,” Dr. Butler said in an interview.
Another expert was even more dismissive of sotagliflozin’s role.
“There is no persuasive evidence that sotagliflozin has any advantages, compared with the SGLT2 inhibitors, for the treatment of heart failure,” said Milton Packer, MD, a heart failure specialist and trialist at Baylor University Medical Center, Dallas. “I do not see why U.S. physicians might pivot from established SGLT2 inhibitors to sotagliflozin,” unless it was priced “at a very meaningful discount to available SGLT2 inhibitors.”
At the time it announced the FDA’s approval, Lexicon did not provide details on how it would price sotagliflozin. Existing retail prices for dapagliflozin and empagliflozin run about $550-$600/month, a price point that has contributed to slow U.S. uptake of the drug class. But experts anticipate a dramatic shake-up of the U.S. market for SGLT2 inhibitors with expected introduction of a generic SGLT2 inhibitor formulation by 2025, a development that could further dampen sotagliflozin’s prospects.
Other experts are more optimistic about the new agent’s uptake, perhaps none more than Deepak L. Bhatt, MD, MPH, who led both pivotal trials that provide the bulk of sotagliflozin’s evidence package.
In addition to SOLOIST-WHF, Dr. Bhatt also headed the SCORED trial, with 10,584 patients with type 2 diabetes, CKD, and risks for cardiovascular disease randomized to sotagliflozin or placebo and followed for a median of 16 months. The primary result showed that sotagliflozin treatment cut the combined rate of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure by a significant 26% relative to control patients.
A clear MACE benefit
“The data from SOLOIST-WHF and SCORED look at least as good as the data for the SGLT2 inhibitors for heart failure, and what appears to be different are the rates for MI and stroke in SCORED,” said Dr. Bhatt, director of Mount Sinai Heart, New York.
“I believe the rate of major adverse cardiovascular events [MACE] were reduced [in SCORED], and this is different from the SGLT2 inhibitors,” he said in an interview.
In 2022, Dr. Bhatt reported results from a prespecified secondary analysis of SCORED that showed that treatment with sotagliflozin cut the rate of MACE by a significant 21%-26%, compared with placebo. This finding was, in part, driven by the first data to show a substantial benefit from an SGLT inhibitor on stroke rates.
And while SCORED did not report a significant benefit for slowing progression of CKD, subsequent post hoc analyses have suggested this advantage also in as-yet-unpublished findings, Dr. Bhatt added.
But he said he doubted nephrologists will see it as a first-line agent for slowing CKD progression – an indication already held by dapagliflozin, pending for empagliflozin, and also in place for a third SGLT2 inhibitor, canagliflozin (Invokana) – because sotagliflozin lacks clear significant and prespecified evidence for this effect.
Dr. Bhatt also acknowledged the limitation of sotagliflozin compared with the SGLT2 inhibitors as an agent for glucose control, again because of no evidence for this effect from a prospective analysis and no pending indication for type 2 diabetes treatment. But the SCORED data showed a clear A1c benefit, even in patients with severely reduced renal function.
Mostly for cardiologists? ‘Compelling’ reductions in MIs and strokes
That may mean sotagliflozin “won’t get much use by endocrinologists nor by primary care physicians,” commented Carol L. Wysham, MD, an endocrinologist with MultiCare in Spokane, Wash.
Sotagliflozin “will be a cardiology drug,” and will “have a hard time” competing with the SGLT2 inhibitors, she predicted.
Dr. Bhatt agreed that sotagliflozin “will be perceived as a drug for cardiologists to prescribe. I don’t see endocrinologists, nephrologists, and primary care physicians reaching for this drug if it has a heart failure label.” But, he added, “my hope is that the company files for additional indications. It deserves an indication for glycemic control.”
The evidence for a heart failure benefit from sotagliflozin is “valid and compelling,” and “having this option is great,” commented Mikhail N. Kosiborod, MD, a cardiologist, vice president of research at Saint Luke’s Health System, and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. But, he added, “it will be a reasonably tall task for sotagliflozin to come from behind and be disruptive in a space where there are already two well-established SGLT2 inhibitors” approved for preventing heart failure hospitalizations, “with a lot of data to back them up,”
The feature that sets sotagliflozin apart from the approved SGLT2 inhibitors is the “really compelling decrease” it produced in rates of MIs and strokes “that we simply do not see with SGLT2 inhibitors,” Dr. Kosiborod said in an interview.
He also cited results from SCORED that suggest “a meaningful reduction in A1c” when indirectly compared with SGLT2 inhibitors, especially in patients with more severe CKD. The lack of a dedicated A1c-lowering trial or an approved type 2 diabetes indication “will not be a problem for cardiologists,” he predicted, but also agreed that it is less likely to be used by primary care physicians in low-risk patients.
“I can see myself prescribing sotagliflozin,” said Dr. Kosiborod, a SCORED coinvestigator, especially for patients with coexisting type 2 diabetes, heart failure, CKD, and atherosclerotic cardiovascular disease. These patients may get “more bang for the buck” because of a reduced risk for MI and stroke, making sotagliflozin “a solid consideration in these patients if the economic factors align.”
Like others, Dr. Kosiborod cited the big impact pricing will have, especially if, as expected, a generic SGLT2 inhibitor soon comes onto the U.S. market. “Access and affordability are very important.”

Sotagliflozin, a novel agent that inhibits sodium-glucose cotransporter 1 as well as SGLT2, has received marketing approval from the Food and Drug Administration for reducing the risk for cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in patients with heart failure, and also for preventing these same events in patients with type 2 diabetes, chronic kidney disease (CKD), and other cardiovascular disease risk factors.
This puts sotagliflozin in direct competition with two SGLT2 inhibitors, dapagliflozin (Farxiga) and empagliflozin (Jardiance), that already have indications for preventing heart failure hospitalizations in patients with heart failure as well as approvals for type 2 diabetes and preservation of renal function.
Officials at Lexicon Pharmaceuticals, the company that developed and will market sotagliflozin under the trade name Inpefa, said in a press release that they expect U.S. sales of the agent to begin before the end of June 2023. The release also highlighted that the approval broadly covered use in patients with heart failure across the full range of both reduced and preserved left ventricular ejection fractions.
They base this niche target for sotagliflozin on results from the SOLOIST-WHF trial, which randomized 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure and showed a significant 33% reduction in the rate of deaths from cardiovascular causes and hospitalizations and urgent visits for heart failure, compared with control patients during a median 9 months of follow-up. Nearly half of the enrolled patients received their first dose while still hospitalized, while the other half received their first dose a median of 2 days after hospital discharge. The drug appeared safe.
Cutting heart failure rehospitalizations in half
An exploratory post hoc analysis of SOLOIST-WHF showed that treatment with sotagliflozin cut the rate of rehospitalizations roughly in half after both 30 and 90 days compared with control patients, according to an abstract presented at the 2022 annual scientific sessions of the AHA that has not yet been published in a peer-reviewed journal.
The only SGLT2 inhibitor tested so far when initiated in patients during hospitalization for heart failure is empagliflozin, in the EMPULSE trial, which randomized 530 patients. EMPULSE also showed that starting an SGLT2 inhibitor in this setting was safe and resulted in significant clinical benefit, the study’s primary endpoint, defined as a composite of death from any cause, number of heart failure events, and time to first heart failure event, or a 5-point or greater difference in change from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score at 90 days.
In the DELIVER trial, which tested dapagliflozin in patients with heart failure with preserved ejection fraction, roughly 10% of patients started study treatment during or within 30 days of heart failure hospitalization, and in this subgroup, dapagliflozin appeared as effective as it was in the other 90% of patients who did not start the drug during an acute or subacute phase.
Despite the SOLOIST-WHF evidence for sotagliflozin’s safety and efficacy in this economically important clinical setting, some experts say the drug faces an uphill path as it contends for market share against two solidly established, albeit dramatically underused, SGLT2 inhibitors. (Recent data document that 20% or fewer of U.S. patients eligible for treatment with an SGLT2 inhibitor receive it, such as a review of 49,000 patients hospitalized during 2021-2022 with heart failure with reduced ejection fraction.)
Others foresee a clear role for sotagliflozin, particularly because of additional facets of the drug’s performance in trials that they perceive give it an edge over dapagliflozin and empagliflozin. This includes evidence that sotagliflozin treatment uniquely (within the SGLT2 inhibitor class) cuts the rate of strokes and myocardial infarctions, as well as evidence of its apparent ability to lower hemoglobin A1c levels in patients with type 2 diabetes and with an estimated glomerular filtration rate below 30 mL/min per 1.73 m2, a property likely linked to inhibition of SGLT1 in the gut that dampens intestinal glucose absorption.
Sotagliflozin uptake ‘will be a challenge’
“It will be a challenge” for sotagliflozin uptake, given the head start that both dapagliflozin and empagliflozin have had as well-documented agents for patients with heart failure, commented Javed Butler, MD, a heart failure clinician and trialist who is president of the Baylor Scott & White Research Institute in Dallas.
Given the position dapagliflozin and empagliflozin currently have in U.S. heart failure management – with the SGLT2 inhibitor class called out in guidelines as foundational for treating patients with heart failure with reduced ejection fraction and likely soon for heart failure with preserved ejection fraction as well – “I can’t imagine [sotagliflozin] will be considered a preferred option,” Dr. Butler said in an interview.
Another expert was even more dismissive of sotagliflozin’s role.
“There is no persuasive evidence that sotagliflozin has any advantages, compared with the SGLT2 inhibitors, for the treatment of heart failure,” said Milton Packer, MD, a heart failure specialist and trialist at Baylor University Medical Center, Dallas. “I do not see why U.S. physicians might pivot from established SGLT2 inhibitors to sotagliflozin,” unless it was priced “at a very meaningful discount to available SGLT2 inhibitors.”
At the time it announced the FDA’s approval, Lexicon did not provide details on how it would price sotagliflozin. Existing retail prices for dapagliflozin and empagliflozin run about $550-$600/month, a price point that has contributed to slow U.S. uptake of the drug class. But experts anticipate a dramatic shake-up of the U.S. market for SGLT2 inhibitors with expected introduction of a generic SGLT2 inhibitor formulation by 2025, a development that could further dampen sotagliflozin’s prospects.
Other experts are more optimistic about the new agent’s uptake, perhaps none more than Deepak L. Bhatt, MD, MPH, who led both pivotal trials that provide the bulk of sotagliflozin’s evidence package.
In addition to SOLOIST-WHF, Dr. Bhatt also headed the SCORED trial, with 10,584 patients with type 2 diabetes, CKD, and risks for cardiovascular disease randomized to sotagliflozin or placebo and followed for a median of 16 months. The primary result showed that sotagliflozin treatment cut the combined rate of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure by a significant 26% relative to control patients.
A clear MACE benefit
“The data from SOLOIST-WHF and SCORED look at least as good as the data for the SGLT2 inhibitors for heart failure, and what appears to be different are the rates for MI and stroke in SCORED,” said Dr. Bhatt, director of Mount Sinai Heart, New York.
“I believe the rate of major adverse cardiovascular events [MACE] were reduced [in SCORED], and this is different from the SGLT2 inhibitors,” he said in an interview.
In 2022, Dr. Bhatt reported results from a prespecified secondary analysis of SCORED that showed that treatment with sotagliflozin cut the rate of MACE by a significant 21%-26%, compared with placebo. This finding was, in part, driven by the first data to show a substantial benefit from an SGLT inhibitor on stroke rates.
And while SCORED did not report a significant benefit for slowing progression of CKD, subsequent post hoc analyses have suggested this advantage also in as-yet-unpublished findings, Dr. Bhatt added.
But he said he doubted nephrologists will see it as a first-line agent for slowing CKD progression – an indication already held by dapagliflozin, pending for empagliflozin, and also in place for a third SGLT2 inhibitor, canagliflozin (Invokana) – because sotagliflozin lacks clear significant and prespecified evidence for this effect.
Dr. Bhatt also acknowledged the limitation of sotagliflozin compared with the SGLT2 inhibitors as an agent for glucose control, again because of no evidence for this effect from a prospective analysis and no pending indication for type 2 diabetes treatment. But the SCORED data showed a clear A1c benefit, even in patients with severely reduced renal function.

FDA approves buprenorphine injection for opioid use disorder
The medication comes in two formulations: a weekly and a monthly version. The weekly treatment is indicated in patients who have initiated treatment with a single dose of transmucosal buprenorphine or who are already being treated with the drug. The monthly version is for patients already receiving buprenorphine.
“Buprenorphine is an important treatment option for opioid use disorder. Today’s approval expands dosing options and provides people with opioid use disorder a greater opportunity to sustain long-term recovery,” said FDA Commissioner Robert M. Califf, MD, in a release. “The FDA will continue to take the critical steps necessary to pursue efforts that advance evidence-based treatments for substance use disorders, which is a strategic priority under the FDA’s Overdose Prevention Framework,” Dr. Califf added.
The Substance Abuse and Mental Health Services Administration reports that patients receiving medication for OUD have their risk for all-cause mortality cut by 50%.
In its release, the FDA said that it remains committed to increasing treatment options for OUD. Earlier this month, the agency issued a joint letter with SAMHSA to underscore the importance of counseling and other services as part of a comprehensive treatment plan the disorder. It also emphasized that receiving buprenorphine should not be contingent on participating in such services.
Brixadi is approved in both weekly and monthly subcutaneous injectable formulations at varying doses, including lower doses that may be appropriate for patients who do not tolerate higher doses of extended-release buprenorphine that are currently available.
The drug will be available through a Risk Evaluation and Mitigation Strategy program and administered only by health care providers in a health care setting.
The most common adverse reactions associated with the drug include injection-site pain, headache, constipation, nausea, injection-site erythema, injection-site pruritus, insomnia, and urinary tract infections. The FDA reports that such side effects occur in at least 5% of patients.

FDA approves Yuflyma as ninth adalimumab biosimilar
The U.S. Food and Drug Administration has approved the biosimilar adalimumab-aaty (Yuflyma) in a citrate-free, high-concentration formulation, the manufacturer, Celltrion USA, announced today. It is the ninth biosimilar of adalimumab (Humira) to be approved in the United States.
Yuflyma is approved for the treatment of adult patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa. It is also approved for polyarticular juvenile idiopathic arthritis for patients aged 2 years or older, as well as for Crohn’s disease in adults and in pediatric patients aged 6 years or older.
The formulation was approved on the basis of a comprehensive data package of analytic, preclinical, and clinical studies, according to Celltrion USA, “demonstrating that Yuflyma is comparable to the reference product Humira in terms of efficacy, safety, pharmacokinetics, and immunogenicity up to 24 weeks and 1 year following treatment.”
The company conducted a double-blind, randomized phase 3 trial that compared switching from reference adalimumab to Yuflyma with continuing either reference adalimumab or Yuflyma for patients with active rheumatoid arthritis. In that trial, the efficacy, pharmacokinetics, safety, and immunogenicity of Yuflyma and reference adalimumab were comparable after 1 year of treatment, including after switching from reference adalimumab to Yuflyma.
“Currently, more than 80% of patients treated with Humira in the United States rely on a high-concentration and citrate-free formulation of this medication. The availability of a high-concentration and citrate-free formulation adalimumab biosimilar provides an important treatment option for patients with inflammatory diseases who benefit from this effective therapy,” said Jonathan Kay, MD, of the University of Massachusetts, Worcester, in the press release.
The citrate-free formulation is thought to lead to less pain on injection.
Yuflyma will be available in prefilled syringe and autoinjector administration options.
Celltrion USA plans to market the drug in the United States in July 2023. Following the initial launch of 40 mg/0.4 mL, the company plans to launch dose forms of 80 mg/0.8 mL and 20 mg/0.2 mL.
Celltrion USA is also seeking an interchangeability designation from the FDA following the completion of an interchangeability trial of 366 patients with chronic plaque psoriasis. The interchangeability designation would mean that patients successfully switched from Humira to Yuflyma multiple times in the trial. The interchangeability designation would allow pharmacists to autosubstitute Humira with Yuflyma. In these cases, individual state laws control how and whether physicians will be notified of this switch.
If interchangeability is approved for Yuflyma, which the company tentatively expects in the fourth quarter of 2024, it would be just the third interchangeable biosimilar approved by the FDA overall and the second adalimumab biosimilar to be designated as such, after adalimumab-adbm (Cyltezo) in October 2021.
Yuflyma was approved in Canada in December 2021 for 10 indications: rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult Crohn’s disease, adult ulcerative colitis, hidradenitis suppurativa, plaque psoriasis, adult uveitis, and pediatric uveitis.
In February 2022, the European Commission granted marketing authorization for Yuflyma across those 10 indications, as well as for nonradiographic axial spondyloarthritis, pediatric plaque psoriasis, and pediatric Crohn’s disease.
In April 2022, Celltrion USA signed a licensing agreement with AbbVie, the manufacturer of Humira. Under that agreement, Celltrion will pay royalties to AbbVie on sales of their individual biosimilars, and AbbVie agreed to drop all patent litigation.

The U.S. Food and Drug Administration has approved the biosimilar adalimumab-aaty (Yuflyma) in a citrate-free, high-concentration formulation, the manufacturer, Celltrion USA, announced today. It is the ninth biosimilar of adalimumab (Humira) to be approved in the United States.
Yuflyma is approved for the treatment of adult patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa. It is also approved for polyarticular juvenile idiopathic arthritis for patients aged 2 years or older, as well as for Crohn’s disease in adults and in pediatric patients aged 6 years or older.
The formulation was approved on the basis of a comprehensive data package of analytic, preclinical, and clinical studies, according to Celltrion USA, “demonstrating that Yuflyma is comparable to the reference product Humira in terms of efficacy, safety, pharmacokinetics, and immunogenicity up to 24 weeks and 1 year following treatment.”
