The Food and Drug Administration has approved another Tdap vaccine option for use during pregnancy to protect newborns from whooping cough.

The agency on Jan. 9 licensed Adacel (Sanofi Pasteur) for immunization during the third trimester to prevent pertussis in infants younger than 2 months old.

The FDA in October approved a different Tdap vaccine, Boostrix (GlaxoSmithKline), for this indication. Boostrix was the first vaccine specifically approved to prevent a disease in newborns whose mothers receive the vaccine while pregnant.

The Centers for Disease Control and Prevention recommend that women receive a dose of Tdap vaccine during each pregnancy, preferably during gestational weeks 27-36 – and ideally toward the earlier end of that window – to help protect babies from whooping cough, the respiratory tract infection caused by Bordetella pertussis.

Providing a Tdap vaccine – tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine, adsorbed – in the third trimester confers passive immunity to the baby, according to the CDC. It also reduces the likelihood that the mother will get pertussis and pass it on to the infant.

One study found that providing Tdap vaccination during gestational weeks 27-36 was 85% more effective at preventing pertussis in infants younger than 2 months old, compared with providing Tdap vaccination to mothers in the hospital postpartum.

“On average, about 1,000 infants are hospitalized and typically between 5 and 15 infants die each year in the United States due to pertussis,” according to a CDC reference page. “Most of these deaths are among infants who are too young to be protected by the childhood pertussis vaccine series that starts when infants are 2 months old.”

The highly anticipated Alzheimer’s drug lecanemab was granted accelerated approval status on Jan. 6 by the FDA, offering hope where there has been little for patients and their families affected by the devastating disease.

More than 6 million people in the United States live with Alzheimer’s.

It’s not a cure, but the drug, given intravenously every 2 weeks, has shown moderate positive effects in clinical trials in slowing early-stage disease.

But many are wary. As explained in an editorial in the journal The Lancet, “The Alzheimer’s disease community has become accustomed to false hope, disappointment, and controversy.”

Some worry about lecanemab’s safety as some people in clinical trials experienced serious side effects of bleeding and swelling in the brain. Scientists recently attributed a third death to lecanemab, brand name Leqembi, though the drugmaker disputed the medication was the cause.

So what should patients and their families make of this news? Here we answer some of the top questions surrounding the drug.
 

What does the FDA action mean?

The FDA granted accelerated approval to Leqembi after it showed positive trial results in slowing the progression of early-stage disease.

The FDA can grant accelerated approval for drugs that treat serious conditions and fill an unmet medical need while drugs continue to be studied in larger trials.

With the FDA approval in hand, doctors can now prescribe the medication.

Rebecca Edelmayer, PhD, the Alzheimer’s Association senior director of scientific engagement, says that with the FDA’s move, ramping up manufacturing – and eventually nationwide distribution and implementation – will take some time.

“Ask your doctor about availability,” she says. “The main issue is that, without insurance and Medicare coverage of this class of treatments, access for those who could benefit from the newly approved treatment will only be available to those who can pay out-of-pocket. Without coverage, people simply won’t be able to get the treatment.”

The Washington Post reports that with accelerated approval, drugmaker Eisai is expected to immediately apply for full FDA approval, which wouldn’t be likely to come before later this year. Full approval could help clear the path for Medicare coverage of the drug.
 

Potential benefit?

Those who got Leqembi in a clinical trial for 18 months experienced 27% less decline in memory and thinking relative to the group who got a placebo. It also reduced amyloid in the brain, the sticky protein that builds up in the brains of people with Alzheimer’s and is considered a hallmark of the disease.

Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, says, “It’s the first phase 3 study in our field of a disease-modifying drug where the clinical efficacy was very clear.”
 

Concerns about side effects

The drug has raised safety concerns as it has been linked with certain serious adverse events, including brain swelling and bleeding. In the trial, 14% of patients who received the drug experienced side effects that included brain swelling and bleeding, compared with about 11% in the placebo group.

Scientists have reportedly linked three deaths during the clinical trial to lecanemab, though it is unclear whether it caused the deaths.

Dr. Fillit notes that the first two people who died were on blood thinners when they received lecanemab.

“There are things about the use of the drug in the real world that we need to work out, especially in the context of people with comorbidities,” he says.

The third death is a little different, Dr. Fillit says. The patient, who had a stroke, showed signs of vasculitis, or inflammation of the blood vessels.

“We don’t know exactly what happened, but we do know it was very, very rare” among the people involved in the trials, he says.

Dr. Edelmayer says that the most common reported side effects during the trials were infusion-related reactions, headache, and amyloid-related imaging abnormalities (ARIA). According to the FDA, these abnormalities “are known to occur with antibodies of this class. ARIA usually does not have symptoms, although serious and life-threatening events rarely may occur.”

The FDA has added these as warnings to the drug’s label, describing the possible infusion-related reactions as flu-like symptoms, nausea, vomiting, and changes in blood pressure.
 

How much will it cost?

Eisai says that lecanemab will cost $26,500 a year.

In a draft report released in December, the Institute for Clinical and Economic Review said a price ranging from $8,500 to $20,600 a year would make the drug cost-effective. While the group has no authority to set prices, many large health insurers consider its reports when they negotiate prices and some drugmakers take into account ICER’s recommendations when setting prices.

An editorial in The Lancet last month warns that the cost will likely be “prohibitive” for low- and middle-income countries and many health systems don’t have the infrastructure for a widespread rollout.
 

Will Medicare cover it?

The Centers for Medicare & Medicaid Services, which runs Medicare, which covers most people with Alzheimer’s, has indicated it won’t broadly cover amyloid-lowering drugs until the drug gets full U.S. approval based on clinical benefits, as opposed to accelerated approval.

That means people would have to pay thousands out of pocket at first to get it.

The CMS decision effectively denies Medicare coverage of fast-tracked FDA-approved medications for Alzheimer’s disease unless the person is enrolled in an approved clinical trial.

On Dec. 19, the Alzheimer’s Association filed a formal request asking CMS to remove the trial-only requirement and provide full and unrestricted coverage for FDA-approved Alzheimer’s treatments.

CMS says in a statement issued after the announcement: “Because Eisai’s product, lecanemab, was granted accelerated approval by the FDA, it falls under CMS’s existing national coverage determination. CMS is examining available information and may reconsider its current coverage based on this review.”

“If lecanemab subsequently receives traditional FDA approval, CMS would provide broader coverage,” the statement says.
 

Who benefits most from this drug?

Lecanemab is a treatment for people with early-stage Alzheimer’s disease who have amyloid in their brain. This means people with other types of dementia, or those in the later stages of Alzheimer’s disease, are not likely to improve with this drug.

Who makes lecanemab?  

Japan-based Eisai is developing the drug, a monoclonal antibody, in collaboration with the U.S. company Biogen.

What’s the Alzheimer’s Association’s view?

The association urged accelerated FDA approval. In a statement, it says it “welcomes and is further encouraged” by the clinical trial results.

It says data published in the New England Journal of Medicine confirms lecanemab “can meaningfully change the course of the disease for people in the earliest stages of Alzheimer’s disease.”

“We are energized at the progress we are seeing in the research pipeline. The science is telling us that although antiamyloid treatments are not a cure – they are not going to be the end of treating Alzheimer’s – they are certainly the beginning,” Dr. Edelmayer says.
 

Are there alternatives?

The FDA gave accelerated approval to Biogen to produce another drug for Alzheimer’s, Aduhelm (aducanemab), in 2021, but the move was controversial as the drug’s effectiveness was widely questioned. It has since largely been pulled from the market.

Aduhelm had been the first approved early-stage Alzheimer’s treatment since 2003.

The U.S. Food and Drug Administration has approved the anti–amyloid-beta protofibril antibody lecanemab (Leqembi, Eisai) for the treatment of early Alzheimer’s disease.

Like its controversial cousin aducanumab (Aduhelm, Biogen/Eisai), lecanemab was approved under the FDA’s accelerated approval pathway, which can be used to fast-track a drug that provides a meaningful therapeutic advantage over existing treatments for a serious or life-threatening illness.

Unlike aducanumab, however, there was no formal FDA advisory committee meeting on lecanemab prior to approval.

“Alzheimer’s disease immeasurably incapacitates the lives of those who suffer from it and has devastating effects on their loved ones,” Billy Dunn, MD, director of the Office of Neuroscience in the FDA’s Center for Drug Evaluation and Research, said in a press release.

“This treatment option is the latest therapy to target and affect the underlying disease process of Alzheimer’s, instead of only treating the symptoms of the disease,” Dr. Dunn added.

Eisai has reported that lecanemab will cost $26,500 a year.

Modest benefit, adverse events

The FDA noted, “The labeling states that treatment with Leqembi should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was studied in clinical trials.”

The agency approved the treatment on the basis of findings from the CLARITY AD trial, which showed modest cognitive benefit for patients with early AD – but at a cost of increased risk for amyloid-related edema and effusions.

The trial enrolled 1,795 adults with mild cognitive impairment or early Alzheimer’s disease in whom amyloid pathology in the brain had been confirmed. Treatment consisted of lecanemab 10 mg/kg biweekly or matching placebo.

After 18 months of treatment, lecanemab slowed cognitive decline by 27%, compared with placebo, as measured by the Clinical Dementia Rating–Sum of Boxes (CDR-SB). This was an absolute difference of 0.45 points (change from baseline, 1.21 for lecanemab vs. 1.66 with placebo; P < .001).

While the results are “welcome news,” a 0.45-point difference on the CDR-SB might not be clinically meaningful, authors of a recent editorial in The Lancet cautioned.

Amyloid-related imaging abnormalities that manifest as edema or microhemorrhages also occurred in one in five patients taking lecanemab.

In addition, a newly published case report in The New England Journal of Medicine describes a patient with Alzheimer’s disease who was taking lecanemab and who died after experiencing numerous intracerebral hemorrhages during treatment with tissue plasminogen activator (tPA) for acute ischemic stroke.

“The findings raise the possibility of cerebral hemorrhages and necrotizing vasculopathy associated with tPA infusion in a patient with cerebrovascular amyloid who had received lecanemab,” the authors wrote.
 

Alzheimer’s Association reaction

Still, in anticipation of accelerated approval of lecanemab and the antiamyloid drug donanemab (Eli Lilly), which the FDA has also fast-tracked, the Alzheimer’s Association filed a formal request last month with the Centers for Medicare & Medicaid Services asking that it provide full and unrestricted coverage for FDA-approved Alzheimer’s disease treatments.

In a letter addressed to CMS administrator Chiquita Brooks-LaSure, the association asked the agency to remove the requirements for “coverage with evidence development” in its national coverage determination for FDA-approved antiamyloid monoclonal antibodies.

“Each day matters when it comes to slowing the progression of this disease,” Joanne Pike, DrPH, president and CEO for the Alzheimer’s Association, noted in a news release at the time.

“The current CMS policy to severely limit access to these treatments eliminates people’s options, is resulting in continued irreversible disease progression, and contributes to greater health inequities. That’s not acceptable,” Dr. Pike added.

After news of today’s approval was released, Dr. Pike noted in a new release, “The Alzheimer’s Association welcomes and celebrates this action by the FDA. We now have a second approved treatment that changes the course of Alzheimer’s disease in a meaningful way for people in the early stages of the disease.”

Maria C. Carrillo, PhD, chief science officer at the Alzheimer’s Association, called today’s approval “a milestone achievement.”

“The progress we’ve seen in not only this class of treatments but also in the diversification of treatment types and targets over the past few years is exciting and provides real hope to those impacted by this devastating disease,” Dr. Carrillo said.
 

Critical issues

Commenting on the approval, Alvaro Pascual-Leone, MD, PhD, professor of neurology at Harvard Medical School, Boston, and chief medical officer at Linus Health, said FDA approval of lecanemab and its adoption in the clinic represent a “very exciting development and prospect; but arguably some critical issues need to be considered.”

He noted that the health care system “is not currently prepared to cope with the challenges and demands of lecanemab,” as well as future pharmacologic agents.

“First, we need better workflows to identify suitable patients who can most benefit from this treatment,” said Dr. Pascual-Leone. He added that beyond identification of cognitive difficulties, amyloid status will need to be determined.

“Presently, this requires expensive and invasive tests,” such as positron-emission tomography scans or lumbar punctures for cerebrospinal fluid analysis. However, these are not fully covered by insurance companies and would be challenging to fully scale, he noted.

“In addition to screening, health systems will need to resolve the logistics challenges around the administration of lecanemab with twice-monthly infusions and the need for careful longitudinal evaluations for potential side effects,” said Dr. Pascual-Leone.

“While lecanemab may represent the first disease-modifying therapy widely available for early Alzheimer’s disease, the likely more promising approach is the addition of other therapies to lecanemab as part of a multi-intervention strategy combining pharmacologic and nonpharmacologic interventions,” he added.

Dr. Pascual-Leone has served as a paid member on scientific advisory boards for Neuroelectrics, Magstim, TetraNeuron, Skin2Neuron, MedRhythms, and Hearts Radiant and is a cofounder of TI Solutions and Linus Health.

Amyloid-related imaging abnormalities that manifest as edema or microhemorrhages also occurred in one in five patients taking lecanemab.

In addition, a newly published case report in The New England Journal of Medicine describes a patient with Alzheimer’s disease who was taking lecanemab and who died after experiencing numerous intracerebral hemorrhages during treatment with tissue plasminogen activator (tPA) for acute ischemic stroke.

“The findings raise the possibility of cerebral hemorrhages and necrotizing vasculopathy associated with tPA infusion in a patient with cerebrovascular amyloid who had received lecanemab,” the authors wrote.
 

Alzheimer’s Association reaction

Still, in anticipation of accelerated approval of lecanemab and the antiamyloid drug donanemab (Eli Lilly), which the FDA has also fast-tracked, the Alzheimer’s Association filed a formal request last month with the Centers for Medicare & Medicaid Services asking that it provide full and unrestricted coverage for FDA-approved Alzheimer’s disease treatments.

In a letter addressed to CMS administrator Chiquita Brooks-LaSure, the association asked the agency to remove the requirements for “coverage with evidence development” in its national coverage determination for FDA-approved antiamyloid monoclonal antibodies.

“Each day matters when it comes to slowing the progression of this disease,” Joanne Pike, DrPH, president and CEO for the Alzheimer’s Association, noted in a news release at the time.

“The current CMS policy to severely limit access to these treatments eliminates people’s options, is resulting in continued irreversible disease progression, and contributes to greater health inequities. That’s not acceptable,” Dr. Pike added.

After news of today’s approval was released, Dr. Pike noted in a new release, “The Alzheimer’s Association welcomes and celebrates this action by the FDA. We now have a second approved treatment that changes the course of Alzheimer’s disease in a meaningful way for people in the early stages of the disease.”

Maria C. Carrillo, PhD, chief science officer at the Alzheimer’s Association, called today’s approval “a milestone achievement.”

“The progress we’ve seen in not only this class of treatments but also in the diversification of treatment types and targets over the past few years is exciting and provides real hope to those impacted by this devastating disease,” Dr. Carrillo said.
 

Critical issues

Commenting on the approval, Alvaro Pascual-Leone, MD, PhD, professor of neurology at Harvard Medical School, Boston, and chief medical officer at Linus Health, said FDA approval of lecanemab and its adoption in the clinic represent a “very exciting development and prospect; but arguably some critical issues need to be considered.”

He noted that the health care system “is not currently prepared to cope with the challenges and demands of lecanemab,” as well as future pharmacologic agents.

“First, we need better workflows to identify suitable patients who can most benefit from this treatment,” said Dr. Pascual-Leone. He added that beyond identification of cognitive difficulties, amyloid status will need to be determined.

“Presently, this requires expensive and invasive tests,” such as positron-emission tomography scans or lumbar punctures for cerebrospinal fluid analysis. However, these are not fully covered by insurance companies and would be challenging to fully scale, he noted.

“In addition to screening, health systems will need to resolve the logistics challenges around the administration of lecanemab with twice-monthly infusions and the need for careful longitudinal evaluations for potential side effects,” said Dr. Pascual-Leone.

“While lecanemab may represent the first disease-modifying therapy widely available for early Alzheimer’s disease, the likely more promising approach is the addition of other therapies to lecanemab as part of a multi-intervention strategy combining pharmacologic and nonpharmacologic interventions,” he added.

Dr. Pascual-Leone has served as a paid member on scientific advisory boards for Neuroelectrics, Magstim, TetraNeuron, Skin2Neuron, MedRhythms, and Hearts Radiant and is a cofounder of TI Solutions and Linus Health.

The U.S. Food and Drug Administration has approved the anti–amyloid-beta protofibril antibody lecanemab (Leqembi, Eisai) for the treatment of early Alzheimer’s disease.

Like its controversial cousin aducanumab (Aduhelm, Biogen/Eisai), lecanemab was approved under the FDA’s accelerated approval pathway, which can be used to fast-track a drug that provides a meaningful therapeutic advantage over existing treatments for a serious or life-threatening illness.

Unlike aducanumab, however, there was no formal FDA advisory committee meeting on lecanemab prior to approval.

“Alzheimer’s disease immeasurably incapacitates the lives of those who suffer from it and has devastating effects on their loved ones,” Billy Dunn, MD, director of the Office of Neuroscience in the FDA’s Center for Drug Evaluation and Research, said in a press release.

“This treatment option is the latest therapy to target and affect the underlying disease process of Alzheimer’s, instead of only treating the symptoms of the disease,” Dr. Dunn added.

Eisai has reported that lecanemab will cost $26,500 a year.

Modest benefit, adverse events

The FDA noted, “The labeling states that treatment with Leqembi should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was studied in clinical trials.”

The agency approved the treatment on the basis of findings from the CLARITY AD trial, which showed modest cognitive benefit for patients with early AD – but at a cost of increased risk for amyloid-related edema and effusions.

The trial enrolled 1,795 adults with mild cognitive impairment or early Alzheimer’s disease in whom amyloid pathology in the brain had been confirmed. Treatment consisted of lecanemab 10 mg/kg biweekly or matching placebo.

After 18 months of treatment, lecanemab slowed cognitive decline by 27%, compared with placebo, as measured by the Clinical Dementia Rating–Sum of Boxes (CDR-SB). This was an absolute difference of 0.45 points (change from baseline, 1.21 for lecanemab vs. 1.66 with placebo; P < .001).

Food and Drug Administration officials are concerned about the safety of legal cannabis-infused foods and supplements and may recommend regulating the products later in 2023, according to a new report.

The products can have drug-like effects on the body and contain CBD (cannabidiol) and THC (tetrahydrocannabinol). Both CBD and THC can be derived from hemp, which was legalized by Congress in 2018. 

“Given what we know about the safety of CBD so far, it raises concerns for FDA about whether these existing regulatory pathways for food and dietary supplements are appropriate for this substance,” FDA Principal Deputy Commissioner Janet Woodcock, MD, told The Wall Street Journal. 

A 2021 FDA report valued the CBD market at $4.6 billion and projected it to quadruple by 2026. The only FDA-approved CBD product is an oil called Epidiolex, which can be prescribed for the seizure-associated disease epilepsy. Research on CBD to treat other diseases is ongoing.

Food, beverage, and beauty products containing CBD are sold in stores and online in many forms, including oils, vaporized liquids, and oil-based capsules, but “research supporting the drug’s benefits is still limited,” the Mayo Clinic said.

Recently, investigations have found that many CBD products also contain THC, which can be derived from legal hemp in a form that is referred to as Delta 8 and produces a psychoactive high. The CDC warned in 2022 that people “mistook” THC products for CBD products, which are often sold at the same stores, and experienced “adverse events.”

The Centers for Disease Control and Prevention and FDA warn that much is unknown about CBD and delta-8 products. The CDC says known CBD risks include liver damage; interference with other drugs you are taking, which may lead to injury or serious side effects; drowsiness or sleepiness; diarrhea or changes in appetite; changes in mood, such as crankiness; potential negative effects on fetuses during pregnancy or on babies during breastfeeding; or unintentional poisoning of children when mistaking THC products for CBD products or due to containing other ingredients such as THC or pesticides.

“I don’t think that we can have the perfect be the enemy of the good when we’re looking at such a vast market that is so available and utilized,” Norman Birenbaum, a senior FDA adviser who is working on the regulatory issue, told the Journal. “You’ve got a widely unregulated market.”

The Food and Drug Administration has approved semaglutide 2.4 mg (Wegovy), a once-weekly subcutaneous injection, for the additional indication of treating obesity in adolescents aged 12 years and older.

This is defined as those with an initial body mass index at or above the 95th percentile for age and sex (based on CDC growth charts). Semaglutide must be administered along with lifestyle intervention of a reduced calorie meal plan and increased physical activity.

When Wegovy was approved for use in adults with obesity in June 2021, it was labeled a “game changer.”

The new approval is based on the results of the STEP TEENS phase 3 trial of once-weekly 2.4 mg of semaglutide in adolescents 12- to <18 years old with obesity, the drug’s manufacturer, Novo Nordisk, announced in a press release.

In STEP TEENS, reported at Obesity Week 2022 in November, and simultaneously published in the New England Journal of Medicine, adolescents with obesity treated with semaglutide for 68 weeks had a 16.1% reduction in BMI compared with a 0.6% increase in BMI in those receiving placebo. Both groups also received lifestyle intervention. Mean weight loss was 15.3 kg (33.7 pounds) among teens on semaglutide, while those on placebo gained 2.4 kg (5.3 pounds).

At the time, Claudia K. Fox, MD, MPH, codirector of the Center for Pediatric Obesity Medicine at the University of Minnesota – who was not involved with the research – told this news organization the results were “mind-blowing ... we are getting close to bariatric surgery results” in these adolescent patients with obesity.

Semaglutide is a GLP-1 agonist, as is a related agent, also from Novo Nordisk, liraglutide (Saxenda), a daily subcutaneous injection, which was approved for use in adolescents aged 12 and older in December 2020. Wegovy is the first weekly subcutaneous injection approved for use in adolescents.

Other agents approved for obesity in those older than 12 in the United States include the combination phentermine and topiramate extended-release capsules (Qsymia) in June 2022, and orlistat (Alli). Phentermine is approved for those aged 16 and older.

Lupin Pharmaceuticals is recalling four lots of quinapril tablets because of unacceptable levels of the nitrosamine impurity, N-nitroso-quinapril, a potential carcinogen.

Nitrosamines “may increase the risk of cancer if people are exposed to them above acceptable levels over long periods of time,” the company says in a recall notice posted on the Food and Drug Administration website.

Lupin says it “has received no reports of illness that appear to relate to this issue.”

Quinapril is an ACE inhibitor used to treat hypertension. Lupin stopped marketing quinapril tablets in September 2022.

The recalled product – quinapril tablets USP 20 mg and 40 mg – are packaged in 90-count bottles and were distributed nationwide to U.S. wholesalers, drug chains, mail order pharmacies, and supermarkets between March 15, 2021, and Sept. 1, 2022.

Lupin is notifying customers to immediately stop distribution of the recalled product and is arranging for the affected product lots to be returned to the company.

The company is advising patients to continue taking their medication and to contact their pharmacist, physician, or healthcare professional for advice regarding an alternative treatment.

Questions regarding this recall should be directed to Inmar Rx Solutions at (877) 538-8445 Monday to Friday between 9:00 a.m. to 5:00 p.m. EST.

Patients and physicians are also advised to report any adverse events or side effects related to the affected products to MedWatch, the FDA’s Safety Information and Adverse Event Reporting program.

Pfizer recalled several lots of quinapril owing to the presence of the same impurity in March 2022and again in April.

The U.S. Food and Drug Administration has approved mosunetuzumab-axgb (Lunsumio) for use in patients with relapsed or refractory follicular lymphoma who have received at least two previous systemic therapies.

This product is a first-in-class bispecific antibody that is designed to target CD20 on the surface of B cells and CD3 on the surface of T cells. This dual targeting activates and redirects a patient’s existing T cells to engage and eliminate target B cells by releasing cytotoxic proteins into the B cells, according to the manufacturer, Genentech.

Mosunetuzumab-axgb is administered as an intravenous infusion for a fixed duration, which allows for time off therapy, and can be infused in an outpatient setting, the company noted.

The drug was granted an accelerated approval on the basis of response rate data from the phase 2 GO29781 trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial, the company noted.

The GO29781 study was carried out in individuals with pretreated follicular lymphoma, including those who were at high risk for disease progression or whose disease was refractory to prior therapies.

A complete response was achieved in 60% of patients (54 of 90).

An objective response rate (a combination of complete and partial responses) was seen in 80% of patients who received the drug, with a majority maintaining responses for at least 18 months.

The median duration of response among those who responded was 22.8 months.

Safety data come from 218 patients with hematologic cancers who received mosunetuzumab-axgb at the recommended dose. The most common adverse event was cytokine release syndrome (39%), which can be severe and life-threatening. The median duration of cytokine release syndrome events was 3 days (range, 1-29 days). Other common adverse events (≥ 20%) included fatigue, rash, pyrexia, and headache.

“This approval is a significant milestone for people with relapsed or refractory follicular lymphoma, who have had limited treatment options until now,” said Elizabeth Budde, MD, PhD, from the City of Hope, Los Angeles, division of lymphoma, and clinical trial investigator.

Dr. Budde presented data on mosunetuzumab-axgb at the 2021 annual meeting of the American Society of Hematology, as reported by this news organization.

She noted that the 60% complete response rate seen with this new drug contrasts with the 14% that has been seen for historical controls.

“We have seen deep and durable responses in heavily pretreated, high-risk relapsed/refractory follicular lymphoma patients with fixed-duration treatment. We also observed a very favorable tolerability profile, with most cytokine release syndrome confined to cycle 1 and low grade, and treatment administration is without mandatory hospitalization,” she commented at the time.

A lymphoma specialist who was not involved in the study told this news organization at the time that he was favorably impressed by the findings.

“To me, the single-agent data looks really outstanding, with a response rate of 80%, a complete response rate of 60%, and a median duration of response of 23 months, and really very acceptable rates of cytokine release syndrome,” commented Brad S. Kahl, MD, from the Siteman Cancer Center and Washington University in St. Louis.

“I think as a single agent – if it does get approval – it will be a really valuable addition to the armamentarium in follicular lymphoma,” he added.

The median duration of response among those who responded was 22.8 months.

Safety data come from 218 patients with hematologic cancers who received mosunetuzumab-axgb at the recommended dose. The most common adverse event was cytokine release syndrome (39%), which can be severe and life-threatening. The median duration of cytokine release syndrome events was 3 days (range, 1-29 days). Other common adverse events (≥ 20%) included fatigue, rash, pyrexia, and headache.

“This approval is a significant milestone for people with relapsed or refractory follicular lymphoma, who have had limited treatment options until now,” said Elizabeth Budde, MD, PhD, from the City of Hope, Los Angeles, division of lymphoma, and clinical trial investigator.

Dr. Budde presented data on mosunetuzumab-axgb at the 2021 annual meeting of the American Society of Hematology, as reported by this news organization.

She noted that the 60% complete response rate seen with this new drug contrasts with the 14% that has been seen for historical controls.

“We have seen deep and durable responses in heavily pretreated, high-risk relapsed/refractory follicular lymphoma patients with fixed-duration treatment. We also observed a very favorable tolerability profile, with most cytokine release syndrome confined to cycle 1 and low grade, and treatment administration is without mandatory hospitalization,” she commented at the time.

A lymphoma specialist who was not involved in the study told this news organization at the time that he was favorably impressed by the findings.

“To me, the single-agent data looks really outstanding, with a response rate of 80%, a complete response rate of 60%, and a median duration of response of 23 months, and really very acceptable rates of cytokine release syndrome,” commented Brad S. Kahl, MD, from the Siteman Cancer Center and Washington University in St. Louis.

“I think as a single agent – if it does get approval – it will be a really valuable addition to the armamentarium in follicular lymphoma,” he added.

The U.S. Food and Drug Administration has approved mosunetuzumab-axgb (Lunsumio) for use in patients with relapsed or refractory follicular lymphoma who have received at least two previous systemic therapies.

This product is a first-in-class bispecific antibody that is designed to target CD20 on the surface of B cells and CD3 on the surface of T cells. This dual targeting activates and redirects a patient’s existing T cells to engage and eliminate target B cells by releasing cytotoxic proteins into the B cells, according to the manufacturer, Genentech.

Mosunetuzumab-axgb is administered as an intravenous infusion for a fixed duration, which allows for time off therapy, and can be infused in an outpatient setting, the company noted.

The drug was granted an accelerated approval on the basis of response rate data from the phase 2 GO29781 trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial, the company noted.

The GO29781 study was carried out in individuals with pretreated follicular lymphoma, including those who were at high risk for disease progression or whose disease was refractory to prior therapies.

The U.S. Food and Drug Administration has approved the medication lenacapavir (Sunlenca) for adults living with multidrug resistant HIV-1 infection. After the initial doses are completed – given both orally and via subcutaneous injection – the drug is administered by injection every 6 months.
 

“Following today’s decision from the FDA, lenacapavir helps to fill a critical unmet need for people with complex prior treatment histories and offers physicians a long-awaited twice-yearly option for these patients who otherwise have limited therapy choices,” said site principal investigator Sorana Segal-Maurer, MD, a professor of clinical medicine at Weill Cornell Medicine, New York, in a statement.

HIV drug regimens generally consist of two or three HIV medicines combined in a daily pill. In 2021, the FDA approved the first injectable complete drug regimen for HIV-1, Cabenuva, which can be administered monthly or every other month. Lenacapavir is administered only twice annually, but it is also combined with other antiretrovirals. The injections and oral tablets of lenacapavir are estimated to cost $42,250 in the first year of treatment and then $39,000 annually in the subsequent years, Reuters reported.

Lenacapavir is the first of a new class of drug called capsid inhibitors to be FDA-approved for treating HIV-1. The drug blocks the HIV-1 virus’s protein shell and interferes with essential steps of the virus’s evolution. The approval, announced today, was based on a multicenter clinical trial of 72 patients with multidrug resistant HIV-1 infection. After a year of the medication, 30 (83%) of the 36 patients randomly assigned to take lenacapavir, in combination with other HIV medications, had undetectable viral loads.

“Today’s approval ushers in a new class of antiretroviral drugs that may help patients with HIV who have run out of treatment options,” said Debra Birnkrant, MD, director of the division of antivirals in the FDA’s Center for Drug Evaluation and Research, in a press release. “The availability of new classes of antiretroviral medications may possibly help these patients live longer, healthier lives.”

A new drug application for a first-in-class photodynamic (PDT) therapy for treating early-stage cutaneous T-cell lymphoma (CTCL) has been submitted to the Food and Drug Administration based on phase 3 findings published in JAMA Dermatology.

The treatment employs an ointment formulation of synthetic hypericin (HyBryte), a photosensitizer, that is preferentially absorbed into malignant cells and activated with visible light – rather than ultraviolet light – approximately 24 hours later. Investigators saw significant clinical responses in both patch and plaque type lesions and across races during the 24-week placebo-controlled, double-blinded, phase 3, randomized clinical trial.

“Traditional phototherapy, ultraviolet B phototherapy, has a limited depth of penetration, so patients with thicker plaque lesions don’t respond as well ... and UVB phototherapy typically is less effective in penetrating pigmented skin,” Ellen J. Kim, MD, lead author of the FLASH phase 3 trial, said in an interview.

Visible light in the yellow-red spectrum (500-650 nm) “penetrates deeper into the skin” and is nonmutagenic in vitro, so “theoretically it should have a much more favorable long-term safety profile,” said Dr. Kim, a dermatologist at the University of Pennsylvania, Philadelphia.

Currently, she said, the risk of secondary malignancies inherent with UV PDT, including melanoma, is a deterrent for some patients, especially “patients with really fair skin and a history of skin cancer.”

Hypericin PDT also seems well suited for use with an at-home light unit. “In our field, it’s not about which therapy is [universally] better or best, but a matter of what works best for each patient at that moment in time, depending on the side-effect profile and other issues such as access,” Dr. Kim said. “It will be great to have another option for an incurable disease that requires chronic management.”

Mycosis fungoides (MF)/CTCL is considered an orphan disease, and the treatment has received orphan drug and fast track designations from the FDA, and orphan designation from the European Medicines Agency, according to a press release from its developer, Soligenix. The company is anticipating potential approval in the second half of 2023 and is targeting early 2024 for a U.S. launch, the statement said.

Phase 3 results

The pivotal trial involved 169 patients at 39 academic and community-based U.S. medical centers and consisted of several 6-week cycles of twice-weekly treatment punctuated by 2-week breaks. In cycle 1, patients were randomized 2:1 to receive hypericin or placebo treatment of three index lesions. Cycle 2 involved the crossover of placebo patients to active treatment of index lesions, and cycle 3 (optional) involved open-label treatment of all desired lesions (index and nonindex).

The trial defined the primary endpoint in phase 1 as 50% or greater improvement in the modified Composite Assessment of Index Lesion Severity score – a tool that’s endorsed by U.S. and international MF/CTCL specialty group consensus guidelines. For cycles 2 and 3, open-label response rates were secondary endpoints. Responses were assessed after 2-week rest periods to allow for treatment-induced skin reactions to subside.

After one cycle of treatment, topical hypericin PDT was more effective than placebo (an index lesion response rate of 16% vs. 4%; P =.04). The index lesion response rate with treatment increased to 40% after two cycles and 49% after three cycles. All were statistically significant changes.

Response rates were similar in patch and plaque-type lesions and regardless of age, sex, race, stage IA versus IB, time since diagnosis, and number of prior therapies. Adverse events were primarily mild application-site skin reactions. No serious drug-related adverse events occurred, Dr. Kim said, and “we had a low drop-out rate overall.”
 

Into the real world

The 24-week phase 3 trial duration is short, considering that “typically, phototherapy takes between 4 to 24 months [to achieve] full responses in CTCL,” Dr. Kim said in the interview.

So with real-world application, she said, “we’ll want to see where the overall response peaks with longer treatment, what the effects are of continuous treatment without any built-in breaks, and whether we will indeed see less skin cancer development in patients who are at higher risk of developing skin cancers from light treatment.”

Such questions will be explored as part of a new 4-year, 50-patient, open-label, multicenter study with the primary aim of investigating home-based hypericin PDT therapy in a supervised setting, said Dr. Kim, principal investigator of this study. Patients who are doing well after 6 weeks of twice-weekly therapy will be given at-home light units to continue therapy and achieve 1 year of treatment with no breaks. They will be monitored with video-based telemedicine.

“Long term, having a home unit should really improve patient access and compliance and hopefully effectiveness,” Dr. Kim said. Based on the phase 3 experience, “we think that continuous treatment will be well tolerated and that we may see greater responses.”

On Dec. 19, Soligenix announced that enrollment had begun in a phase 2a study of synthetic hypericin for treating patients with mild to moderate psoriasis.

Dr. Kim reported to JAMA Dermatology grants from Innate Pharma and Galderma; consulting/advisory fees from Almirall, Galderma, and Helsinn; and honoraria from Ology and UptoDate.

The Food and Drug Administration has requested that Oncopeptides withdraw the U.S. marketing authorization for its multiple myeloma drug Pepaxto (melphalan flufenamide), the company announced in a press release.
 

The drug was granted an accelerated approval by the FDA in February 2021, for use in combination with dexamethasone in adults with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy.

However, the phase 3 OCEAN study raised concerns about safety, as it showed a higher mortality associated with melphalan flufenamide in the experimental arm, compared with pomalidomide (Pomalyst).

The FDA already flagged this issue in July 2021, issuing a safety alert flagging the increased risk for death observed in the OCEAN trial among patients receiving melphalan flufenamide versus pomalidomide (47.6% vs. 43.4%) and a 5.3-month shorter overall survival.

The issue was also discussed in September 2022 by FDA’s Oncologic Drugs Advisory Committee, which voted 14-to-2 against maintaining the accelerated approval, citing an unfavorable risk/benefit profile.

The company stopped marketing the drug in the United States in October 2021 at the FDA’s request but continued to make it available for patients already undergoing treatment.

However, in March 2022, Oncopeptides rescinded the letter that voluntarily withdrew the agent from market, after further review of overall survival data from the OCEAN trial led the company to reconsider its decision. Notably, marketing efforts were still discontinued while the company worked with the FDA to interpret the data, it stated in the press release.

That review of the data showed that progression-free survival was 42% higher with melphalan flufenamide versus pomalidomide and overall response rates were 32.1% versus 26.5%, respectively.

Now, the FDA has requested that the company withdraw its U.S. marketing authorization.

“We respect FDA’s accelerated approval regulations,” Jakob Lindberg, CEO of Oncopeptides commented in the press release.

However, he also added, “multiple myeloma remains an incurable disease, and the treatment options for patients with triple-class refractory disease will ultimately become exhausted. The OCEAN study demonstrated clinical benefit for multiple myeloma patients, in particular for nontransplanted elderly patients where the unmet medical need remains very high.”

Commercialization of the drug in Europe, under the brand name Pepaxti, is ongoing.

“Pepaxti has a full approval from the European Medicines Agency, EMA, since Aug. 18, 2022, and was approved by the Medicines and Healthcare Products Regulatory Agency, MHRA, in the U.K. on Nov 11, 2022,” the company noted.

However, in March 2022, Oncopeptides rescinded the letter that voluntarily withdrew the agent from market, after further review of overall survival data from the OCEAN trial led the company to reconsider its decision. Notably, marketing efforts were still discontinued while the company worked with the FDA to interpret the data, it stated in the press release.

That review of the data showed that progression-free survival was 42% higher with melphalan flufenamide versus pomalidomide and overall response rates were 32.1% versus 26.5%, respectively.

Now, the FDA has requested that the company withdraw its U.S. marketing authorization.

“We respect FDA’s accelerated approval regulations,” Jakob Lindberg, CEO of Oncopeptides commented in the press release.

However, he also added, “multiple myeloma remains an incurable disease, and the treatment options for patients with triple-class refractory disease will ultimately become exhausted. The OCEAN study demonstrated clinical benefit for multiple myeloma patients, in particular for nontransplanted elderly patients where the unmet medical need remains very high.”

Commercialization of the drug in Europe, under the brand name Pepaxti, is ongoing.

“Pepaxti has a full approval from the European Medicines Agency, EMA, since Aug. 18, 2022, and was approved by the Medicines and Healthcare Products Regulatory Agency, MHRA, in the U.K. on Nov 11, 2022,” the company noted.
