The U.S. Food and Drug Administration has approved canakinumab (Ilaris) for the treatment of gout flares in adults who cannot be treated with NSAIDs, colchicine, or repeated courses of corticosteroids. The drug is also indicated for people who could not tolerate or had an inadequate response to NSAIDs or colchicine.

The drug, a humanized anti–interleukin-1 beta monoclonal antibody, is the first and only biologic approved in the United States for the treatment of gout flares, according to Novartis. It is administered in a single, subcutaneous injection of 150 mg.

“At Novartis, we are committed to bringing medicines that address high unmet needs to patients. We are proud to receive approval on our eighth indication for Ilaris in the U.S. and provide the first biologic medicine option for people with gout flares to help treat this painful and debilitating condition,” the company said in a statement to this news organization.

Canakinumab was first approved in the United States in 2009 for the treatment of children and adults with cryopyrin-associated periodic syndrome (CAPS). Since then, it has been approved for the treatment of several other autoinflammatory diseases, including Still’s disease and recurrent fever syndromes.

In 2011, an FDA advisory panel voted against the approval of canakinumab to treat acute gout flares refractory to NSAIDs, colchicine, or repeated courses of corticosteroids, while in 2013, the European Medicine Agency approved the drug for this treatment indication.

Since that FDA advisory committee meeting and the FDA’s subsequent rejection letter, “[Novartis] has conducted additional studies in patients with gout flares and other related populations to further characterize the short- and long-term safety of canakinumab supporting the current application. To further support the benefit-risk [profile of the drug], the indication is for a more restricted population than initially proposed in 2011,” the FDA’s Center for Drug Evaluation and Research said in a statement to this news organization. “Given these considerations and the available safety information, the Agency determined that canakinumab, at the recommended dosage, has a favorable risk-benefit profile” in the specified patient population.

The Food and Drug Administration has approved natalizumab-sztn injection (Tyruko, Sandoz), the first biosimilar to Biogen’s Tysabri (natalizumab), to treat adults with relapsing forms of multiple sclerosis, including clinically isolated syndrome, relapsing remitting MS, and active secondary progressive disease.

“Biosimilar medications offer additional effective treatment options that have the potential to increase access for people living with relapsing forms of multiple sclerosis. [This] approval could have a meaningful impact for patients managing their disease,” Paul R. Lee, MD, PhD, director of the division of neurology II, FDA Center for Drug Evaluation and Research, said in a statement.

The natalizumab biosimilar is given using the same dosing and administration schedule. Like the reference product, it is indicated for adults with moderately to severely active Crohn’s disease unresponsive to other medications.

The approval of the natalizumab biosimilar is based on results of the phase 3 Antelope trial, which showed no clinically meaningful differences between it and the reference product.

The trial included 264 adults (mean age, 36 years; 61% women) with relapsing remitting MS from 48 centers in seven Eastern European countries.

All were randomly assigned to receive intravenous infusions every 4 weeks of 300 mg of the natalizumab biosimilar or the reference product for a total of 12 infusions.

At 24 and 48 weeks, there were no between-group differences in annualized relapse rates or Expanded Disability Status Scale scores, which were similar between treatment groups at baseline. There were also no significant differences in safety, tolerability, or immunogenicity.

The prescribing information for both natalizumab products includes a boxed warning about the increased risk of progressive multifocal leukoencephalopathy (PML), a viral infection of the brain that usually leads to death or severe disability.

Risk factors for the development of PML include the presence of antibodies to the JC virus, longer duration of therapy, and prior use of immunosuppressants.

“These factors should be considered in the context of expected benefit when initiating and continuing treatment with natalizumab products, and health care providers should monitor patients and withhold treatment immediately at the first sign or symptom suggestive of PML,” the FDA advises.

Because of the risks of PML, natalizumab products are available only through a restricted drug distribution program under a risk evaluation and mitigation strategy.

In a statement, Sandoz said it’s committed to having the product available in the United States “as soon as possible.”

One in five women in the United States undergoing maternity care experiences mistreatment from health care providers, based on survey data from more than 2,000 individuals.

“We have to do better at providing respectful and unbiased care to all mothers,” Debra E. Houry, MD, chief medical officer of the Centers for Disease Control and Prevention, said in a press briefing announcing the findings, which were published as a Vital Signs report in the CDC’s Morbidity and Mortality Weekly Report.

Previous research showed an increase in maternal deaths in the United States from 17.4 to 32.9 per 100,000 live births between 2018 and 2021, but approximately 80% of these deaths are preventable, wrote Yousra A. Mohamoud, PhD, of the CDC’s division of reproductive health, and colleagues.

Dr. Mohamoud

“Maternal mortality review committees have identified discrimination as one factor contributing to pregnancy-related deaths,” the researchers wrote. Respectful care must be part of a larger strategy to prevent these deaths, they emphasized.

In the report, researchers reviewed data from 2,402 women who responded to an opt-in survey. The survey was conducted for the CDC through Porter Novelli, and no personally identifying information was included. Nearly 70% of the participants were White, 10.7% were Black, 10.2% were Hispanic, 4.8% were Asian, 1.5% were American Indian, Alaska Native, Pacific Islander, or Native Hawaiian, 2.8% were multiracial, and 0.5% were another race.

The survey included questions about maternity care experiences during pregnancy and delivery of the youngest child. For 65.5% of respondents, their youngest child was 5 years or older at the time of the survey.

Mistreatment during maternity care was defined using seven validated questions, including questions about violations of physical privacy, verbal abuse, and inattention to requests for help. Satisfaction with maternity care was defined as “very satisfied” or “somewhat satisfied.”

Participants also responded to questions about discrimination during maternity care based on factors such as race, ethnicity, skin color, age, and weight. Finally, participants were asked whether they refrained from asking questions about their health or raising concerns with health care providers.

Overall, 20.4% of respondents reported experiencing one of the defined forms of mistreatment during maternity care. The most common mistreatment reported by the women was being ignored by providers when they requested help (9.7%), followed by being shouted at or scolded (6.7%), having physical privacy violated (5.1%), and being forced to accept unwanted treatment or threatened with withholding of treatment (4.6%).

However, approximately 90% of women overall and 75% of those who reported any mistreatment were very or somewhat satisfied with their maternity care.

When stratified by race, mistreatment was reported most frequently by Black, Hispanic, and multiracial women (30%, 29%, and 27%, respectively).

Overall, 29% of women reported experiencing some type of discrimination; the most frequently reported reasons were age, weight, and income. Black women reported the highest rates of discrimination (40%) followed by multiracial women (39%) and Hispanic women (37%).

With regard to self-advocacy, 45% of women reported holding back from asking questions of health care providers; the most common reasons were thinking their health concerns were normal for pregnancy, being embarrassed, and being concerned that health care providers would consider them difficult.

In addition, more women with no insurance or public insurance at the time of delivery reported mistreatment during their maternity care than did women with private insurance (28%, 26%, and 16%, respectively).

The findings were limited by several factors, including the opt-in nature of the survey, which means that the data are likely not representative of the birthing population in the United States, the researchers noted. Other limitations included the reliance on self-reports, potential recall bias, use of English language only, and use of a combined category for respondents of American Indian, Alaska Native, Native Hawaiian, and Pacific Islander ethnicity.

However, the results highlight the need for improving respectful care as part of a larger strategy to reduce pregnancy-related deaths, the researchers said. At the system level, quality improvement programs are needed to standardize care and support providers in recognizing and reducing biases and increasing cultural awareness and communication. At the provider level, clinicians at all points in the maternity care process can improve patient experiences by providing equitable and respectful care, and by listening to and addressing patients’ concerns.

In addition, communication campaigns and community engagement can include perspectives of patients, families, and communities to support women and encourage them to ask questions and express concerns, the researchers said.

Improving respectful care can be part of actions to reduce mortality at all levels, the researchers noted. The Hear Her campaign, developed by the CDC Foundation with funding from Merck, provides resources for pregnant and postpartum women and their support networks to help reduce pregnancy-related deaths and complications by encouraging women to share concerns with providers and to recognize urgent maternal warning signs.

The study received no outside funding. The researchers had no financial conflicts to disclose.

The Centers for Disease Control and Prevention is tracking a newly discovered strain of COVID-19 called BA.2.86.

On Aug. 17, the agency posted on X, formerly known as Twitter, that the lineage has been detected in the United States, Denmark, and Israel. 

“As we learn more about BA.2.86, CDC’s advice on protecting yourself from COVID-19 remains the same,” the CDC said on X. 

A case of BA.2.86 was detected at a laboratory at the University of Michigan, CBS News reported. It’s not clear how the university obtained the sample that was sequenced. A case was also detected in the United Kingdom, the news outlet said. 

The World Health Organization is also tracking BA.2.86 and has classified it as a “variant under monitoring.” 

“More data are needed to understand this COVID-19 variant and the extent of its spread, but the number of mutations warrants attention. WHO will update countries and the public as we learn more,” the WHO said on X.

The strain is so new that scientists don’t know if BA.2.86 is more easily spread, causes more severe symptoms than existing strains, or will be more resistant to vaccines and natural immunity developed over the last few years. 

Early research indicates BA.2.86 “will have equal or greater escape than XBB.1.5 from antibodies elicited by pre-Omicron and first-generation Omicron variants,” Jesse Bloom, PhD, a virologist at the Fred Hutchinson Cancer Center, said in a slide deck published Aug. 17. (XBB.1.5 is the Omicron subvariant that is targeted in the updated COVID booster shot to be released soon.)

Still, Dr. Bloom noted that “even if a highly mutated new variant like BA.2.86 starts to spread, we will be in a far better place than we were in 2020 and 2021, since most people have some immunity to SARS-CoV-2 now.”

Although this sterilization process helps keep medical devices – and patients – safe, the odorless, flammable gas may also be harming people who live near sterilization plants and who may inhale the compound, which has been linked to an elevated risk of cancer.

Regulatory agencies are currently feuding over the best way to address the dilemma: preserving patient safety versus protecting public health. Lawmakers are weighing in on the matter, which has been the source of multiple civil lawsuits filed by individuals who say they have suffered health problems as a result of exposure to ethylene oxide.

The Environmental Protection Agency and the U.S. Food and Drug Administration agree that use of the compound should be limited, but they are at odds about how quickly limits should be put in place, according to Axios.

A new commercial standard for ethylene oxide proposed by the EPA in April would impose stricter emission restrictions for sterilization facilities and chemical plants – a move that would cut ethylene oxide emissions by 80%, the EPA estimates.

While the FDA says it “shares concerns about the release of ethylene oxide at unsafe levels into the environment,” the agency cautions that moving too fast to cut emissions would disrupt the medical supply chain, which is already experiencing turbulence. The U.S. has been facing the worst drug supply shortages in a decade in addition to severe medical device shortages.

Currently, other methods of sterilization cannot replace the use of ethylene oxide for many devices. Ethylene oxide is used to sterilize about half of all medical devices in the U.S., the FDA says. Given the country’s reliance on this compound for sterilization, the FDA says it is “equally concerned about the potential impact of shortages of sterilized medical devices that would result from disruptions in commercial sterilizer facility operations.”

In 2019, Illinois temporarily closed a sterilization facility over concern regarding ethylene oxide emissions. The closure caused a shortage of a pediatric breathing tube.

Some lawmakers agree that an Interior-Environment bill would require FDA certification that any action by the EPA would not cause a medical device shortage.

The FDA has been working to identify safe alternatives to ethylene oxide for sterilizing medical supplies as well as strategies to reduce emissions of ethylene oxide by capturing the gas or by turning it into a harmless byproduct. In 2019, the FDA launched a pilot program to incentivize companies to develop new sterilization technologies.

“The FDA remains focused in our commitment to encourage novel ways to sterilize medical devices while reducing adverse impacts on the environment and public health and developing solutions to avoid potential shortages of devices that the American public relies upon,” the agency said.

Several signs are pointing to an impending surge in the number of human cases of West Nile virus in several regions of the United States.

West Nile virus is spread by infected mosquitoes and currently there is no cure or virus-specific treatment. In rare cases, it can be deadly. It can infect humans, birds, horses, and other mammals.

West Nile Virus is the leading cause of mosquito-borne disease in the continental United States. As of Aug. 8, 126 human cases had been identified across 22 states, according to the Centers for Disease Control and Prevention.

“Particularly here in California, it’s peak risk right now,” said Vicki Kramer, PhD, chief of vector-borne diseases in the California Department of Public Health. She said scientists there are seeing higher mosquito and infected mosquito numbers.
 

“Peak risk right now”

Dead birds are tested for the virus and by Aug. 4, 181 of the 913 birds tested in California have been positive, three times the total testing positive by this time in 2022.

“Last year at this time, we had 60 positive dead birds out of 817 tested,” Dr. Kramer said.

Severe flooding and high heat can contribute to the rise in mosquito populations and many parts of the country have seen plenty of both.

One of the ways scientists track infected mosquito patterns in California is by using flocks of strategically placed sentinel chickens.

“Chickens are a mosquito magnet,” Dr. Kramer said.

Chickens don’t get sick with the virus, but they do build antibodies to it. Surveillance teams check their blood every other week to track the virus.

Daniel Pastula, MD, MHS, chief of neuroinfectious diseases and global neurology at the University of Colorado School of Medicine and the Colorado School of Public Health, said the state is watching troubling signs as well.

“The concern this year,” Dr. Pastula said, “particularly along the Front Range in Colorado, is we’ve found many more mosquitoes [that are] positive for West Nile earlier in the season compared with other years.

“We’re bracing for higher-than-baseline human cases,” he said.

Asked about this year’s first human case, reported in Toronto, a region with a long winter and low incidence of the virus, he said that provides a further example that people need to be prepared even in climates not known to be mosquito-dense.

He added, however, that climate is only one factor in the severity of the season. Others include birds’ immunity and migratory patterns.

Dr. Pastula said that fluctuations in temperature and rainfall are rising with climate change and are disrupting normal baseline levels of West Nile.

“That shows we need to be prepared for West Nile virus and other mosquito-borne diseases in any place in North America or really the world. We recently saw malaria cases in the southern United States. It just shows you how dangerous mosquitoes can be.”
 

Avoid mosquito bites

Dr. Pastula and Dr. Kramer list the precautions people can take to protect themselves from West Nile virus:

• Limit outdoor exposure particularly at dusk and dawn.
• Wear protective clothing.
• Use .
• Repair window screens so mosquitoes cannot fly through.
• Dump and drain standing water on your property and maintain swimming pools.

Dr. Pastula noted that summer is the time human cases start to mount – typically from July and August to the first hard freeze.

“We have been warning people here up and down the Front Range of Colorado to take prevention very seriously,” Dr. Pastula said.

He pointed out that 80% who are infected with West Nile will have no symptoms.

About 20% will have flu-like illness – high fever, body and joint aches, rash, diarrhea, or headaches. Symptoms may last for weeks. About 1% of the time, he said, people can get neuroinvasive West Nile.

Dr. Pastula explained that the virus can infect the covering of the brain and spinal cord causing meningitis with very high fever, severe headaches, stiff neck, and sensitivity to light.

So far this year, there have been 89 neuroinvasive cases reported nationally, according to the CDC.

With West Nile encephalitis, the virus “can infect the brain itself causing altered mental status, movement disorders, or weakness,” Dr. Pastula said.

Sometimes it can infect the gray matter of the spinal cord causing a West Nile virus poliomyelitis, which brings polio-like symptoms.

“The West Nile encephalitis and poliomyelitis can cause permanent deficits or even death,” he said. “It’s uncommon but it’s not trivial.”

Several vaccine candidates are in development, Dr. Pastula said, but none has reached clinical trials. Part of the reason for that, he said, is that scientists must be able to predict the timing of an outbreak.

“We’re not really great at predicting outbreaks,” he said.

Although the risk for neuroinvasive disease is small, it can be higher in certain groups, he said – those who are over age 60 years or are immunocompromised; those who have diabetes, cancer, or kidney disease; or those who have undergone organ transplants.

Those infected should see a health care professional and may be able to get relief with the usual medications for flu-like illness.

Some with severe infection may need to go to the hospital, Dr. Pastula said.

The U.S. Food and Drug Administration (FDA) has granted accelerated approval to talquetamab-tgvs (Talvey, Janssen Biotech, Inc), a first-in-class bispecific antibody targeting the GPRC5D receptor, for heavily pretreated adults with relapsed or refractory multiple myeloma.

Patients must have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.

The agent, which also received breakthrough and orphan drug designation, is available only through the Tecvayli-Talvey Risk Evaluation and Mitigation Strategy (REMS) because of a boxed warning for life-threatening or fatal cytokine release syndrome (CRS) and neurological toxicity, including immune effector cell–associated neurotoxicity (ICANS), the FDA announced.

Talquetamab-tgvs was evaluated in the single-arm, open-label MonumenTAL-1 study of 187 patients who had previously been treated with at least four prior systemic therapies.

The overall response rate in 100 patients who received a subcutaneous dose of 0.4 mg/kg weekly was 73% and median duration of response was 9.5 months. The overall response rate in 87 patients who received a subcutaneous dose of 0.8 mg/kg biweekly was 73.6%, with about 85% of responders maintaining their response for at least 9 months. In this group, the median duration of response was not estimable.

Patients in the 0.4 mg/kg weekly dose group were treated following two step-up doses in the first week of therapy, and those in the 0.8 mg/kg biweekly group were treated following three step-up doses, until disease progression or unacceptable toxicity.

Adverse reactions occurring in at least 20% of the 339 patients in the safety population included CRS, dysgeusia (foul, metallic taste sensation), nail disorder, musculoskeletal pain, skin disorder, rash, fatigue, decreased weight, dry mouth, pyrexia, xerosis, dysphagia, upper respiratory tract infection, and diarrhea.

Both the weekly 0.4 mg/kg and biweekly 0.8 mg/kg doses are recommended. The full dosing schedule is included in the prescribing information.

The approval follows a series of market withdrawals for other multiple myeloma drugs that initially received accelerated FDA approval. For instance, the FDA recently requested withdrawal of melphalan flufenamide (Pepaxto) after 2021 confirmatory trial results showed an increased risk of death. This agent had received accelerated approval in 2021. GlaxoSmithKline’s blood cancer drugs panobinostat (Farydak) and belantamab mafodotin-blmf (Blenrep) were also withdrawn based on confirmatory trial results.

Continued approval of talquetemab-tgvs for this indication is also contingent on verifying efficacy in confirmatory trials.

The new treatment approach represents a “welcome addition to the myeloma community,” Michael Andreini, president and chief executive officer of the Multiple Myeloma Research Foundation stated in a Janssen press release. “Although options for the treatment of multiple myeloma have expanded significantly in recent years, the disease remains incurable, and therefore, patients are in need of new treatment options.”

Health care professionals should report all serious adverse events suspected to be associated with the use of any medicine and device to FDA’s MedWatch Reporting System or by calling 1-800-FDA-1088.

The U.S. Food and Drug Administration has approved dostarlimab-gxly (Jemperli, GlaxoSmithKline) with carboplatin and paclitaxel, followed by single-agent dostarlimab, for primary advanced or recurrent endometrial cancer that is mismatch repair–deficient (dMMR), as determined by an FDA-approved test or microsatellite instability–high (MSI-H).

The approval was based on GSK’s RUBY trial. Across 122 patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer, progression-free survival was 30.3 months in women randomly assigned to dostarlimab on a background of carboplatin and paclitaxel, followed by dostarlimab monotherapy, vs. 7.7 months among women randomly assigned to placebo (hazard ratio, 0.29; P < .0001), according to the FDA’s press release.

MMR/MSI tumor status was determined by local testing or by the Ventana MMR RxDx Panel when local testing was unavailable.

“Until now, chemotherapy alone has been the standard of care with many patients experiencing disease progression,” GSK executive Hesham Abdullah said in the company’s press release. The trial results “and today’s approval underscore our belief in the potential for Jemperli to transform cancer treatment as a backbone immuno-oncology therapy.”

Dostarlimab was already approved in the United States as monotherapy for adults with dMMR recurrent or advanced endometrial cancer that has progressed on or following a platinum-containing chemotherapy and is not a candidate for curative surgery or radiation. The latest approval means that the agent “is now indicated earlier in treatment in combination with chemotherapy,” GSK said.

Dostarlimab also carries an indication for dMMR recurrent or advanced solid tumors that have progressed on or following prior treatment when there are no satisfactory alternative treatment options.

Immune-mediated adverse reactions with dostarlimab include pneumonitis, colitis, hepatitis, endocrinopathies such as hypothyroidism, nephritis with renal dysfunction, and skin adverse reactions. The most common adverse reactions (≥ 20%) with carboplatin and paclitaxel in the Ruby trial were rash, diarrhea, hypothyroidism, and hypertension.

The recommended dostarlimab dose is 500 mg every 3 weeks for 6 doses with carboplatin and paclitaxel, followed by 1,000 mg monotherapy every 6 weeks until disease progression or unacceptable toxicity, or up to 3 years.

Drugs.com lists dostarlimab’s price at $11,712.66 for 500 mg/10 mL intravenous solution.

The U.S. Food and Drug Administration has approved dostarlimab-gxly (Jemperli, GlaxoSmithKline) with carboplatin and paclitaxel, followed by single-agent dostarlimab, for primary advanced or recurrent endometrial cancer that is mismatch repair–deficient (dMMR), as determined by an FDA-approved test or microsatellite instability–high (MSI-H).

The approval was based on GSK’s RUBY trial. Across 122 patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer, progression-free survival was 30.3 months in women randomly assigned to dostarlimab on a background of carboplatin and paclitaxel, followed by dostarlimab monotherapy, vs. 7.7 months among women randomly assigned to placebo (hazard ratio, 0.29; P < .0001), according to the FDA’s press release.

MMR/MSI tumor status was determined by local testing or by the Ventana MMR RxDx Panel when local testing was unavailable.

On July 21, 2023, topical cantharidin became the first Food and Drug Administration–approved treatment of molluscum contagiosum (molluscum), for adults and pediatric patients 2 years of age and older.

The product is a drug-device combination that contains a formulation of cantharidin solution (0.7%), delivered topically via a single-use applicator, which allows for precise dosing and targeted administration. According to a press release from Verrica Pharmaceuticals, cantharidin is expected to be available by September 2023 and should be administered only by a trained health care professional; it is not for use in the home.

The approval of the product, also known as VP-102, is based on results from two identical multicenter phase 3 randomized, double-blind, placebo-controlled trials that evaluated the drug’s safety and efficacy in patients 2 years of age and older diagnosed with molluscum: Cantharidin Application in Molluscum Patients-1 (CAMP-1) and CAMP-2. Patients in both trials met the primary endpoint of complete clearance of all treatable molluscum lesions. Specifically, 46% of CAMP-1 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 18% of participants in the vehicle group (P < .0001), while 54% of CAMP-2 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 13% of participants in the vehicle group (P < .0001).

A post hoc analysis of both trials found that complete clearance of all lesions was significantly higher in the VP-102 group than vehicle across all body regions. It also found that there were no serious adverse reactions reported in the trials. Adverse reactions were mostly mild to moderate and included application site vesicles, erythema, pain, dryness, scab, discoloration, pruritus, and edema.

The product will be marketed as Ycanth.

In March of 2023, the FDA accepted a new drug application for another treatment for molluscum contagiosum, berdazimer gel 10.3%. That product is being developed by Novan.

The Food and Drug Administration has approved quizartinib (Vanflyta) for adults with acute myeloid leukemia (AML) that carries the FLT3-ITD genetic mutation.

On July 20 the FDA also approved the LeukoStrat CDx FLT3 Mutation Assay to determine whether patients have this mutation.

The agency granted quizartinib a first-line indication for use in combination with standard chemotherapy – cytarabine and anthracycline induction followed by cytarabine consolidation – and as maintenance monotherapy afterwards, in adults whose tumors express FLT3-ITD.

The FLT3 protein is a tyrosine kinase receptor found on hematopoietic stem cells. Wild-type FLT3 promotes cell survival, growth, and differentiation, but ITD (internal tandem duplication)-mutated FLT3, which quizartinib targets, is associated with a higher relapse risk and shorter survival. About a quarter of AML patients carry the mutation. 

Approval was based on the phase 3 QuANTUM-First trial in over 500 patients with the mutation. Median overall survival among patients on standard chemotherapy randomly assigned to quizartinib was 31.9 months versus 15.1 months in patients randomly assigned to placebo, a 22.4% reduction in the risk of death (P = .0324).

Quizartinib is not indicated as maintenance monotherapy after allogeneic hematopoietic stem cell transplantation.

In a company press release, the drug’s manufacturer Daiichi Sankyo said quizartinib will be available in the United States soon.

Company executive Ken Takeshita, MD, called the approval “an important milestone, as patients with the FLT3-ITD subtype of AML can now be treated with the first-ever FLT3 inhibitor approved across the three phases of treatment these patients typically receive.”

The FDA’s original decision date was April 24, but the agency pushed it back 3 months to review updates Daiichi Sankyo made to quizartinib’s Risk Evaluation and Mitigation Strategies (REMS) program in response to an agency request.

Quizartinib carries a boxed warning of QT prolongation, torsades de pointes, and cardiac arrest. Because of these risks, it’s only available through a new program, dubbed “Vanflyta REMS.”

In the trial, the most common adverse with quizartinib included lymphopenia (60%), hypokalemia (59%), hypoalbuminemia (53%), hypophosphatemia (52%), alkaline phosphatase increased (51%), hypomagnesemia (44%), febrile neutropenia (44%), diarrhea (42%), mucositis (38%), nausea (34%), and hypocalcemia (33%), among others.

The most common grade 3/4 adverse events were febrile neutropenia (43% with quizartinib vs. 41% with placebo), neutropenia (18% vs. 9%), hypokalemia (19% vs. 16%), and pneumonia (11% both). Adverse events were fatal in 11.3% of patients receiving quizartinib versus 9.7% of patients on placebo, mostly caused by infections.

In 2019, the FDA rejected quizartinib for FLT3-ITD mutated relapsed/refractory AML monotherapy in adults, after most of its oncology advisers thought the risk of treatment outweighed the benefits in an earlier trial.
