The Food and Drug Administration has expanded the indication for Abbott Laboratories’ spinal cord stimulation (SCS) devices to include treatment of chronic back pain in patients who have not had, or are not eligible for, back surgery, the company has announced.
 

The new indication spans all of Abbott’s SCS devices in the United States, which include the recharge-free Proclaim SCS family and the rechargeable Eterna SCS platform.

The devices feature the company’s proprietary, low-energy BurstDR stimulation waveform, a form of stimulation therapy that uses bursts of mild electrical energy without causing an abnormal tingling sensation to help disrupt pain signals before they can reach the brain, the company explained.

The expanded indication was supported by results from the DISTINCT study, which enrolled 270 adults suffering from severe, disabling chronic back pain for an average of more than 12 years and who were not eligible for surgery.

The study showed that significantly more patients who were treated with SCS achieved significant improvements in back pain, function, quality of life, and psychological status than peers treated with conservative medical management.

“To date, we have struggled with how to treat people who weren’t considered a good surgical candidate because we didn’t have clear, data-driven treatment options for non-surgical back pain,” Timothy Deer, MD, president and CEO of the Spine and Nerve Centers of the Virginias in Charleston, W.Va., said in a news release.

“This new indication for Abbott’s SCS devices, together with BurstDR stimulation, allows physicians the ability to identify and treat a new group of people, providing them with relief from chronic back pain,” Dr. Deer said.

The Centers for Disease Control and Prevention is alerting clinicians to be on the lookout for a severe antifungal-resistant form of tinea, as it was recently detected in two patients in New York.

Tinea, or ringworm, one of the most common fungal infections, is responsible for almost 5 million outpatient visits and 690 hospitalizations annually, according to the CDC.

Over the past 10 years, severe, antifungal-resistant tinea has spread in South Asia, in part because of the rise of a new dermatophyte species known as Trichophyton indotineae, wrote the authors of a report on the two patients with the drug-resistant strain. This epidemic “has likely been driven by misuse and overuse of topical antifungals and corticosteroids,” added the authors, in Morbidity and Mortality Weekly Report.

The cases were detected by a New York City dermatologist. In the first case, a 28-year-old woman developed a widespread pruritic eruption in the summer of 2021. She did not consult a dermatologist until December, when she was in the third trimester of pregnancy. She had large, annular, scaly, pruritic plaques on her neck, abdomen, pubic region, and buttocks, but had no underlying medical conditions, no known exposures to someone with a similar rash, and no recent international travel history.

After she gave birth in January, she started oral terbinafine therapy but had no improvement after 2 weeks. Clinicians administered a 4-week course of itraconazole, which resolved the infection.

The second patient, a 47-year-old woman with no medical conditions, developed a rash while in Bangladesh in the summer of 2022. Other family members had a similar rash. She was treated with topical antifungal and steroid combination creams but had no resolution. Back in the United States, she was prescribed hydrocortisone 2.5% ointment and diphenhydramine, clotrimazole cream, and terbinafine cream in three successive emergency department visits. In December 2022, dermatologists, observing widespread, discrete, scaly, annular, pruritic plaques on the thighs and buttocks, prescribed a 4-week course of oral terbinafine. When the rash did not resolve, she was given 4 weeks of griseofulvin. The rash persisted, although there was 80% improvement. Clinicians are now considering itraconazole. The woman’s son and husband are also being evaluated, as they have similar rashes.

In both cases, skin culture isolates were initially identified as Trichophyton mentagrophytes. Further analysis at the New York State Department of Health’s lab, using Sanger sequencing of the internal transcribed spacer region of the ribosomal gene, followed by phylogenetic analysis, identified the isolates as T. indotineae.

The authors note that culture-based techniques used by most clinical laboratories typically misidentify T. indotineae as T. mentagrophytes or T. interdigitale. Genomic sequencing must be used to properly identify T. indotineae, they wrote.

Clinicians should consider T. indotineae in patients with widespread ringworm, especially if they do not improve with topical antifungals or oral terbinafine, said the authors. If T. indotineae is suspected, state or local public health departments can direct clinicians to testing.

The authors report no relevant financial relationships.

The Food and Drug Administration has approved the oral medication fezolinetant (Veozah) for the treatment of moderate to severe hot flashes in menopausal women, according to an FDA statement. The approved dose is 45 mg once daily.

Fezolinetant, a neurokinin 3 (NK3) receptor antagonist, is the first drug of its kind to earn FDA approval for the vasomotor symptoms associated with menopause, according to the statement. The drug works by binding to the NK3 receptor, which plays a role in regulating body temperature, and blocking its activity. Fezolinetant is not a hormone, and can be taken by women for whom hormones are contraindicated, such as those with a history of vaginal bleeding, stroke, heart attack, blood clots, or liver disease, the FDA stated.

The approval was based on data from the SKYLIGHT 2 trial, results of which were presented at the annual meeting of the Endocrine Society, reported by this news organization, and published in the Journal of Clinical Endocrinology and Metabolism.

In the two-phase trial, women were randomized to 30 mg or 45 mg of fezolinetant or a placebo. After 12 weeks, women in placebo groups were rerandomized to fezolinetant for a 40-week safety study.

The study population included women aged 40-65 years, with an average minimum of seven moderate-to-severe hot flashes per day. The study included 120 sites in North America and Europe.

At 12 weeks, both placebo and fezolinetant patients experienced reductions in moderate to severe vasomotor symptoms of approximately 60%, as well as a significant decrease in vasomotor symptom severity.

The FDA statement noted that patients should undergo baseline blood work before starting fezolinetant to test for liver infection or damage, and the prescribing information includes a warning for liver injury; blood work should be repeated at 3, 6, and 9 months after starting the medication, according to the FDA and a press release from the manufacturer Astellas.

The most common side effects associated with fezolinetant include abdominal pain, diarrhea, insomnia, back pain, hot flashes, and elevated liver values, according to the FDA statement. The FDA granted Astellas Pharma’s application a Priority Review designation. Astellas has priced the drug at $550 for a 30-day supply, significantly higher than the Institute for Clinical and Economic Review’s previously recommended range of $2,000 to $2,500 per year.

The U.S. Food and Drug Administration has approved pegunigalsidase alfa (Elfabrio, Chiesi Global Rare Diseases/Protalix BioTherapeutics), an enzyme replacement therapy (ERT) to treat adults with confirmed Fabry disease.

Fabry disease is a rare inherited X-linked lysosomal disorder caused by a deficiency of the enzyme alpha-galactosidase A (GLA), which leads to the buildup of globotriaosylceramide (GL-3) in blood vessels, kidneys, the heart, nerves, and other organs, increasing the risk for kidney failure, myocardial infarction, stroke, and other problems.

Elfabrio delivers a functional version of GLA. It’s given by intravenous infusion every 2 weeks.

Evidence for safety, tolerability, and efficacy of Elfabrio stems from a comprehensive clinical program in more than 140 patients with up to 7.5 years of follow up treatment.

It has been studied in both ERT-naïve and ERT-experienced patients. In one head-to-head trial, Elfabrio was non-inferior in safety and efficacy to agalsidase beta (Fabrazyme, Sanofi Genzyme), the companies said in a press statement announcing approval.

“The totality of clinical data suggests that Elfabrio has the potential to be a long-lasting therapy,” Dror Bashan, president and CEO of Protalix, said in the statement.

Patients treated with Elfabrio have experienced hypersensitivity reactions, including anaphylaxis. In clinical trials, 20 (14%) patients treated with Elfabrio experienced hypersensitivity reactions; 4 patients (3%) experienced anaphylaxis reactions that occurred within 5-40 minutes of the start of the initial infusion.

Before administering Elfabrio, pretreatment with antihistamines, antipyretics, and/or corticosteroids should be considered, the label advises.

Patients and caregivers should be informed of the signs and symptoms of hypersensitivity reactions and infusion-associated reactions and instructed to seek medical care immediately if such symptoms occur.

A case of membranoproliferative glomerulonephritis with immune depositions in the kidney was reported during clinical trials. Monitoring serum creatinine and urinary protein-to-creatinine ratio is advised. If glomerulonephritis is suspected, treatment should be stopped until a diagnostic evaluation can be conducted.

The Food and Drug Administration has approved the antipsychotic brexpiprazole (Rexulti, Otsuka and Lundbeck) for agitation associated with Alzheimer’s disease (AD), making it the first FDA-approved drug for this indication.

“Agitation is one of the most common and challenging aspects of care among patients with dementia due to Alzheimer’s disease,” Tiffany Farchione, MD, director of the division of psychiatry in the FDA’s Center for Drug Evaluation and Research, said in a news release.

Agitation can include symptoms that range from pacing or restlessness to verbal and physical aggression. “These symptoms are leading causes of assisted living or nursing home placement and have been associated with accelerated disease progression,” Dr. Farchione said.

Brexpiprazole was approved by the FDA in 2015 as an adjunctive therapy to antidepressants for adults with major depressive disorder and for adults with schizophrenia.

Approval of the supplemental application for brexpiprazole for agitation associated with AD dementia was based on results of two randomized, double-blind, placebo-controlled studies.

In both studies, patients who received 2 mg or 3 mg of brexpiprazole showed statistically significant and clinically meaningful improvements in agitation symptoms, as shown by total Cohen-Mansfield Agitation Inventory (CMAI) score, compared with patients who received placebo.

The recommended starting dosage for the treatment of agitation associated with AD dementia is 0.5 mg once daily on days 1-7; it was increased to 1 mg once daily on days 8-14 and then to the recommended target dose of 2 mg once daily.

The dosage can be increased to the maximum recommended daily dosage of 3 mg once daily after at least 14 days, depending on clinical response and tolerability.

The most common side effects of brexpiprazole in patients with agitation associated with AD dementia include headache, dizziness, urinary tract infection, nasopharyngitis, and sleep disturbances.

The drug includes a boxed warning for medications in this class that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.

The supplemental application for brexpiprazole for agitation had fast-track designation.

The supplemental application for brexpiprazole for agitation had fast-track designation.

SAN DIEGO – A COVID-19 combination antiviral is the most important new drug primary care physicians have prescribed in recent years – plus it has helped keep many patients out of the hospital, according to a presenter at the annual meeting of the American College of Physicians.

Nirmatrelvir-ritonavir was granted emergency use authorization by the FDA late in 2021 to prevent progression to severe disease when COVID-19 cases and deaths were surging, and the Delta and Omicron variants started to spread.

Gerald Smetana, MD, an internist at Beth Israel Deaconess Medical Center in Boston, discussed nirmatrelvir-ritonavir as an example of how new drugs relevant to primary care can have a profound impact on public health.
 

Understanding the mechanism of action

Nirmatrelvir is the active agent of this combination and inhibits the SARS-CoV-2 main protease (Mpro), which is required for viral replication. In contrast to the SARS-CoV-2 spike protein, Mpro is highly conserved in coronaviruses and rarely acquires mutations. Therefore, unlike monoclonal antibodies targeting the spike protein, nirmatrelvir is active against known Omicron variants and is predicted to remain active against new variants that may emerge. The HIV1 protease inhibitor ritonavir has no activity against SARS-CoV-2. It can help increase the serum concentration of nirmatrelvir by inhibiting its metabolization.

“Although the details are not important for prescribing internists, having a basic understanding of the mechanism of action can help [doctors] better understand for which patients the drugs are indicated,” said Dr. Smetana, also a professor of medicine at Harvard Medical School, Boston. This is particularly important for newly approved drugs with a lot of new information to digest.

“Knowing the mechanisms of action of new drugs can help us predict their efficacy and potential side effects,” said Hubertus Kiefl, MD, an internist at Beth Israel Deaconess Medical Center and a lecturer at Harvard Medical School, during an interview after the session.

Understanding how drugs work also can help clinicians make better decisions, such as avoiding the use of a monoclonal antibody during a surge of a new variant with mutations in surface proteins or carefully managing the use of nirmatrelvir-ritonavir in patients who take certain medications that would cause potentially serious drug-drug interactions, Dr. Kiefl added.

Nirmatrelvir-ritonavir reduces the risk of hospitalization – but only in high-risk patients.

Dr. Smetana presented published data from the EPIC-HR study, a pivotal phase 2-3 clinical trial in 2,246 adult patients with COVID-19, all of whom were unvaccinated. Additionally, all patients had at least one risk factor for progression to severe disease.

When initiated 5 days after symptom onset or earlier, treatment with 300 mg nirmatrelvir plus 100 mg ritonavir twice a day for 5 days led to an 89% relative risk reduction in COVID-19–related hospitalization or death through day 28, compared with placebo.

Subgroup analyses showed that some patients benefited more than others. The highest risk reduction after treatment with nirmatrelvir-ritonavir was observed in patients at least 65 years old.

“It is important to remember that all the patients of this study were unvaccinated and [had] not had prior SARS-CoV-2 infection. This study population isn’t representative of most patients we are seeing today,” said Dr. Smetana.

Unpublished data from a study of standard-risk patients showed a nonsignificant reduction in the risk of hospitalization or death, he said. The study was stopped because of the low rates of hospitalization and death.
 

Effective in real world, but less so than in clinical trials

The fact that the patient cohort in the EPIC-HR trial was different from the patients internists see today makes real-world data critical for determining the usefulness of nirmatrelvir-ritonavir in everyday practice, Dr. Smetana said.

A real-world study from Israel conducted during the first Omicron wave (January to March 2022) showed that treatment with nirmatrelvir alone substantially reduced the relative risk of hospitalization in adults older than 65, with no evidence of benefit in adults aged 40-65. Dr. Smetana highlighted that, unlike the EPIC-HR cohort, most patients in the Israeli study had prior immunity due to vaccination or prior SARS-CoV-2 infection.
 

Many drug-drug interactions, but they can be managed

Nirmatrelvir-ritonavir interacts with many drugs, some of which are commonly used by primary care patients.

To help internists identify drug-drug interactions, Dr. Smetana proposed the use of the Liverpool COVID-19 Drug Interactions Checker, an intuitive tool that can help prescribers identify potential drug-drug interactions, categorize them based on severity, and identify management strategies.

This tool is specific to COVID-19 drugs. The Liverpool group also offers online drug interaction checkers for HIV, hepatitis, and cancer. “We need more tools like this to help improve the safe use of new drugs,” Dr. Smetana said.

To manage drug interactions, according to Dr. Smetana, U.S. treatment guidelines offer the following three options:

• Prescribe an alternative COVID therapy.
• Temporarily withhold concomitant medication if clinically appropriate.
• Adjust the dose of concomitant medication and monitor for adverse effects.

Medication doses that are withheld or modified should be continued through 3 days after completing nirmatrelvir-ritonavir, he added.
 

Important considerations

Commenting on things to consider for patients with COVID-19, Dr. Smetana said that there is a short window after symptom onset when nirmatrelvir-ritonavir can be prescribed, and safety in pregnancy is not known. There is also uncertainty regarding funding of nirmatrelvir-ritonavir prescriptions after the state of emergency is lifted. He reminded attendees that, although nirmatrelvir-ritonavir is the preferred first-line treatment for high-risk patients, another antiviral agent, molnupiravir, is also available and might be more appropriate for some patients.

He also cautioned about prescribing new drugs off label for indications that are not yet FDA-approved. “We are often stewards of limited resources when new drugs first become available but are not yet in sufficient supply to meet demand. Limiting our prescribing to FDA-approved indications helps to ensure equitable access,” he said.

Dr. Smetana and Dr. Kiefl reported no disclosures.

A panel of independent advisers recently almost unanimously recommended to restrict a new indication for olaparib (Lynparza) alongside abiraterone (Zytiga) in patients with metastatic castration-resistant prostate cancer.

On April 28, members of the Oncologic Drugs Advisory Committee voted 11 to 1, with one abstention, that only patients whose tumors have a BRCA mutation should receive olaparib as part of the combination first-line treatment for metastatic castration-resistant prostate cancer.

Olaparib is already cleared by the Food and Drug Administration for various ovarian, breast, and pancreatic cancer indications as well as later-line use in certain more advanced prostate cancers. AstraZeneca recently applied for an additional, broad indication for the poly (ADP-ribose) polymerase (PARP) inhibitor as an initial therapy that would include patients without BRCA or homologous recombination repair (HRR) mutations.

In reviewing the application, the FDA raised concerns about this broad new indication, highlighting limitations in the key research used to justify the expanded use and highlighting how olaparib may amount to a “toxic placebo,” a phrase agency staff used in their briefing document.

Given these concerns, the FDA reviewers asked the independent ODAC panel to vote on the following question: “As FDA reviews the proposed indication for olaparib in combination with abiraterone for initial treatment of [metastatic castration-resistant prostate cancer], should the indication be restricted to patients whose tumors have a BRCA mutation?”

The ODAC panel voted 11 to 1 in favor of a restricted expansion of olaparib plus abiraterone and prednisone or prednisolone to patients whose tumors have a BRCA mutation. One member – Ravi A. Madan, MD, of the National Cancer Institute – abstained. The FDA staff asked panelists to abstain if they felt the combination treatment should not be approved for any indication.

Overall, the ODAC panel agreed with the FDA staff’s criticism of the research supporting the application: the PROpel study. The trial randomized 796 patients with previously untreated metastatic castration-resistant prostate cancer to olaparib plus abiraterone or abiraterone plus placebo. The median time for radiographic progression-free survival – the study’s primary endpoint – was nearly 25 months in the olaparib group versus 16.6 months in the placebo group.

The combination also demonstrated a 19% reduced risk of death, which was not statistically significant (hazard ratio, 0.81; P = .0544), and a median improvement of 7.4 months in the combination arm (42.1 vs. 34.7 months).

Although the study met its primary endpoint, the results were difficult to interpret given the lack of information about genetic variability in the participants’ tumors. Participants were not prospectively assessed for either BRCA or HRR status. But given the importance of BRCA status as a predictive biomarker for PARP inhibitor efficacy, “this trial design would be considered inappropriate today as the biomarker should have been prospectively evaluated,” the FDA wrote in its briefing document.

In a post hoc analysis performed by the FDA, the agency found that BRCA-positive patients accounted for most of the survival benefit of the combination, though made up only 11% of the PROpel population.

That meant the ODAC members were being asked to evaluate a drug based on “suboptimal data” resulting from a “suboptimal study design,” said Dr. Madan, who is head of the prostate cancer clinical research section in the NCI’s Center for Cancer Research.

Dr. Madan also emphasized concerns the FDA raised about the potential harms for patients whose prostate cancer was not tied to BRCA mutations. In the FDA’s briefing document, the agency said patients treated in the first-line metastatic castration-resistant prostate cancer setting generally have few symptoms at baseline. Adding olaparib among patients lacking the BRCA mutation could expose them to a drug with known side effects but minimal chance to help them.

The PROpel trial also found that patients who received olaparib and abiraterone experienced greater toxicity than those who received abiraterone. These adverse events included venous thromboembolic events, myelosuppression, requirement for blood transfusions, nausea, vomiting, and diarrhea.

Although the FDA is not compelled to follow the recommendations of its advisory committees, it often does.

AstraZeneca expressed some disappointment about the recommendation in a press release. Susan Galbraith, executive vice president of Oncology R&D at AstraZeneca, said, “while we are pleased with the recognition of the benefit of Lynparza plus abiraterone for patients with BRCA-mutated metastatic castration-resistant prostate cancer, we are disappointed with the outcome of today’s ODAC meeting. We strongly believe in the results of the PROpel trial, which demonstrated the clinically meaningful benefit for this combination in a broad population of patients regardless of biomarker status.”

One ODAC member, Jorge J. Nieva, MD, did support the expanded approval for olaparib, casting the single “no” vote. Dr. Nieva, an oncologist at the University of Southern California, Los Angeles, disagreed with the FDA’s question about limiting use of the olaparib-abiraterone combination to patients with known BRCA mutations, citing the positive result from the PROpel trial.

People are aware that olaparib provides a great deal more benefit in the BRCA-positive group and may give “only minimal benefit if these tests are not positive,” but “these risks and benefits can be addressed at the patient and physician level,” he said.

But Terrence M. Kungel, MBA, who served as ODAC’s patient representative for the meeting, offered a counterpoint to Dr. Nieva’s assessment. Patients now often struggle to assess the options available to them and then pay for these medicines, with financial toxicity affecting many people with cancer.

“Prostate cancer patients need more treatments that are effective, not more choices,” said Mr. Kungel, who voted with the majority.

People are aware that olaparib provides a great deal more benefit in the BRCA-positive group and may give “only minimal benefit if these tests are not positive,” but “these risks and benefits can be addressed at the patient and physician level,” he said.

But Terrence M. Kungel, MBA, who served as ODAC’s patient representative for the meeting, offered a counterpoint to Dr. Nieva’s assessment. Patients now often struggle to assess the options available to them and then pay for these medicines, with financial toxicity affecting many people with cancer.

“Prostate cancer patients need more treatments that are effective, not more choices,” said Mr. Kungel, who voted with the majority.

The Food and Drug Administration has approved an expanded indication for atogepant (Qulipta, Abbvie) to include prevention of chronic migraine in adults. The approval makes atogepant the first, and only, oral calcitonin gene-related peptide receptor antagonist approved to prevent migraine across frequencies, including episodic and chronic, the company said in a news release.

The FDA initially approved atogepant in 2021 for the prevention of episodic migraine in adults.

Once-daily atogepant is available in three doses – 10 mg, 30 mg, and 60 mg – for prevention of episodic migraine. However, only the 60-mg dose of medication is indicated for the preventive treatment of chronic migraine.

The expanded indication in chronic migraine is based on positive results of the phase 3 PROGRESS trial, which evaluated atogepant in more than 700 adults with chronic migraine.

The trial met the primary endpoint of statistically significant reduction from baseline in mean monthly migraine days with atogepant compared with placebo across the 12-week treatment period.

Treatment with atogepant also led to statistically significant improvements in all six secondary endpoints, including the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across 12 weeks and improvements in function and reduction in activity impairment caused by migraine.

The efficacy results are consistent with those in the ADVANCE episodic migraine trial.

The overall safety profile of atogepant is consistent with the episodic migraine patient population, with the most common adverse events including constipation, nausea, and fatigue/sleepiness.

“The FDA approval is an important milestone, providing those most impacted by migraine with a new, safe, and effective treatment option in a convenient, once-daily pill,” Peter McAllister, MD, director of the New England Center for Neurology and Headache, Stamford, Conn., said in the news release.

The data demonstrate that atogepant “helps reduce the burden of migraine by delivering improvements in function, with high response rates and sustained efficacy over 12 weeks. These are critical factors neurologists and headache specialists consider when prescribing a treatment option, particularly for those with chronic migraine,” Dr. McAllister added.

The recent approval of the first oral fecal-derived microbiota therapy to prevent the recurrence of Clostridioides difficile (C. diff) infection in patients was welcome news for physicians who’ve struggled under the weight of having too few treatment options for the prevention of C. diff recurrence.

The product, developed by Massachusetts-based Seres Therepeutics and marketed as Vowst, was approved by the U.S. Food and Drug Administration on April 26. It is approved for use in adults who have already been treated with antibiotics for a recurrent infection with C. diff bacteria.

This is the first oral treatment for the prevention of C. diff recurrence and is designed to be delivered in four capsules taken daily for 3 days.

Gastroenterologist Phillip I. Tarr, MD, division chief of gastroenterology at Washington University, St. Louis, and chair of the American Gastroenterological Association Center for Gut Microbiome Research and Education, said that prevention of recurrent C. diff infection “remains challenging,” and that Vowst “provides the first FDA-approved, orally administered microbiome therapeutic with which to achieve this goal. This advance also makes us optimistic we might soon be able to prevent other disorders by managing gut microbial communities.”

Vowst is the second therapy derived from human stool to be approved for the indication in less than 6 months. In December, the FDA approved Rebyota (Ferring), a rectally delivered treatment that also uses microbes from donor feces. Both products were given priority review, orphan drug, and breakthrough therapy designations by the agency.

C. diff infection can be aggravated by an alteration of normal gut flora associated with antibiotics treatment, leading to cycles of repeated infections. Infection can produce diarrhea, abdominal pain, fever, and severe morbidity. In the United States, an estimated 15,000 to 30,000 deaths per year are linked to C. diff. Risk factors for recurrent infection include being 65 or older, hospitalization, being in a nursing home, a weakened immune system, and previous infection with C. diff.

Therapies transplanting fecal microbiota from donors have been used since the 1950s as treatments for recurrent C. diff infection, and in the past decade, as stool banks recruiting screened donors have made fecal microbiota transplants, or FMT, standard of care. However, only in recent years have fecal-derived therapies become subject to standardized safety and efficacy testing.

Both the current FDA-approved products, Rebyota and Vowst, were shown in randomized controlled trials to reduce recurrence of C. diff infection, compared with placebo. In a phase 3 clinical trial of Rebyota (n = 262) in antibiotic-treated patients, one rectally administered dose reduced recurrence of C. diff infection by 70.6% at 8 weeks, compared with 57.5% for placebo. A phase 3 study of Vowst (n = 281) showed recurrence in treated subjects to be 12.4% at 8 weeks, compared with nearly 40% of those receiving placebo (relative risk, 0.32; 95% confidence interval, 0.18-0.58; P less than .001).

Despite screening protocols that have become increasingly homogenized and rigorous, FMT is associated with the risk of introducing pathogens. Vowst is manufactured with purified bacterial spores derived from donor feces, not whole stool. Nonetheless, FDA noted in its statement that Vowst could still potentially introduce infectious agents or allergens.
 

Antibiotics are still first-line treatment

In an interview, Jessica Allegretti, MD, MPH, AGAF, medical director of the Crohn’s and Colitis Center at Brigham & Women’s Hospital, Boston, said that having two FDA-approved therapies with different means of administration “is great for the field and great for patients. These are both meant to be used after a course of antibiotics, so antibiotics are still the mainstay of treatment for C. diff and recurrent C. diff, but we now have more options to prevent recurrence.”

The convenience of an oral therapy that can be taken at home is “very attractive,” Dr. Allegretti added, noting that there will also be patients “who either don’t want to or can’t take capsules, for whom a rectal administration [in a health care setting] may be preferred.”

Dr. Allegretti, who has used FMT to treat recurrent C. difficile for more than a decade, said that she expected traditional FMT using screened donor stool to remain available even as the new products are adopted by clinicians. FMT centers like OpenBiome “will continue to provide access for patients who either don’t have the ability to get the FDA-approved products because of insurance coverage, or for financial reasons, or maybe neither of the new products is appropriate for them,” she said. “I do think there will always be a need for the traditional option. The more options that we have available the better.”

TD Cowen analyst Joseph Thome told Reuters that the drug could be priced close to $20,000 per course, expecting peak sales of $750 million in the U.S. in 2033.

Dr. Allegretti disclosed consulting work for Seres Therapeutics, Ferring, and other manufacturers. She is a member of OpenBiome’s clinical advisory board.

The Food and Drug Administration has approved the first treatment that takes a genetics-based approach to slowing or stopping the progression of a rare form of amyotrophic lateral sclerosis (ALS), the debilitating and deadly disease for which there is no cure.
 

Most people with ALS die within 3-5 years of when symptoms appear, usually of respiratory failure.

The newly approved drug, called Qalsody, is made by the Swiss company Biogen. The FDA fast-tracked the approval based on early trial results. The agency said in a news release that its decision was based on the demonstrated ability of the drug to reduce a protein in the blood that is a sign of degeneration of brain and nerve cells.

While the drug was shown to impact the chemical process in the body linked to degeneration, there was no significant change in people’s symptoms during the first 28 weeks that they took the drug, Biogen said in a news release. But the company noted that some patients did see improved functioning after starting treatment.

“I have observed the positive impact Qalsody has on slowing the progression of ALS in people with SOD1 mutations,” Timothy M. Miller, MD, PhD, researcher and codirector of the ALS Center at Washington University in St. Louis, said in a statement released by Biogen. “The FDA’s approval of Qalsody gives me hope that people living with this rare form of ALS could experience a reduction in decline in strength, clinical function, and respiratory function.”

Qalsody is given to people via a spinal injection, with an initial course of three injections every 2 weeks. People then get the injection once every 28 days.

The new treatment is approved only for people with a rare kind of ALS called SOD1-ALS, which is known for a genetic mutation. While ALS affects up to 32,000 people in the United States, just 2% of people with ALS have the SOD1 gene mutation. The FDA says the number of people in the United States who could use Qalsody is about 500.

In trials, 147 people received either Qalsody or a placebo, and the treatment significantly reduced the level of a protein in people’s blood that is associated with the loss of control of voluntary muscles. 

Because Qalsody received a fast-track approval from the FDA, it must still provide more research data in the future, including from a trial examining how the drug affects people who carry the SOD1 gene but do not yet show symptoms of ALS.
