The US Food and Drug Administration (FDA) has approved vorasidenib (Voranigo, Servier) for the treatment of certain isocitrate dehydrogenase (IDH)–mutant diffuse gliomas, marking the first approval of a targeted therapy for these types of brain tumors.

Specifically, the oral targeted inhibitor of IDH1 and IDH2 was approved for use after surgery in adults and children aged 12 years or older who have grade 2 astrocytoma or oligodendroglioma with a susceptible IDH1 or IDH2 mutation. According to the FDA, surgery includes biopsy, subtotal resection, or gross total resection. 

Mutations in IDH1 are present in around 80% of grade 2 gliomas, whereas IDH2 mutations are more infrequent, occurring in about 4%. 

Prior to the approval, which was based on progression-free survival (PFS) and safety findings from the pivotal phase 3 INDIGO trial, patients with this type of glioma had limited treatment options, said a Servier spokesperson.

The approval of vorasidenib marks “one of the biggest advances in low-grade glioma in more than two decades” and “will empower patients to take active control of their disease with a once-daily pill,” according to the spokesperson.

In the INDIGO trial, 331 patients were randomly assigned to receive 40 mg of vorasidenib once daily (n = 168) or placebo (n = 163). At a median follow-up of 14.2 months, the median PFS was more than twice as long among those who received vorasidenib vs placebo: 27.7 months vs 11.1 months, respectively (hazard ratio [HR] for disease progression or death, 0.39). The time to next intervention was also significantly longer with vorasidenib vs placebo (median not reached vs 17.8 months, respectively; HR, 0.26).

The 61% reduction in the risk for tumor progression or death observed in the trial represents “a significant sign of efficacy that has the potential to change the landscape in this disease,” first author Ingo K. Mellinghoff, MD, of Memorial Sloan Kettering Cancer Center, New York City, told this news organization in 2023, when presenting the findings at the 2023 American Society of Clinical Oncology conference. These findings were simultaneously published in The New England Journal of Medicine.

Glenn Lesser, MD, a discussant at the 2023 meeting, commented on the “striking” findings. The results are “statistically highly significant, and more importantly, they’re clinically very, very significant,” said Dr. Lesser, from Wake Forest Baptist Health in Winston-Salem, North Carolina.

Vorasidenib can also potentially delay the use of toxic chemotherapies and radiation for many years in patients with these tumors, Dr. Lesser added.

Adverse events of grade 3 or higher occurred in 22.8% of those who received vorasidenib and in 13.5% of those in the placebo group. Increased alanine aminotransferase levels of grade 3 or higher occurred in 9.6 vs 0% of patients in the groups, respectively.

The most common adverse reactions with vorasidenib, affecting at least 15% of treated patients, include fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. The most common grade 3 or 4 laboratory abnormalities were increased alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase as well as decreased neutrophils. 

The recommended dose of vorasidenib for adults is 40 mg given orally once daily until disease progression or unacceptable toxicity. In children aged 12 or older, the recommended dose is 40 mg given orally once daily for those weighing ≥ 40 kg, and 20 mg given orally once daily for those weighing < 40 kg.

FDA Approves First Engineered Cell Therapy for a Solid Tumor

Article Type

Wed, 08/07/2024 - 04:43

 

The US Food and Drug Administration (FDA) has approved afamitresgene autoleucel (afami-cel) (Tecelra, Adaptimmune LLC) to treat advanced synovial sarcoma. 

Afami-cel — the first engineered cell therapy for a solid tumor — is indicated specifically for adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are positive for several human leukocyte antigens (HLAs), and whose tumors express melanoma-associated antigen A4, as determined by FDA-authorized companion diagnostic devices.

The single-dose treatment targets solid tumors expressing melanoma-associated antigen A4, a protein highly expressed in synovial sarcoma.

Synovial sarcoma is a rare form of cancer, which affects about 1000 people in the US each year. Malignant cells develop and form a tumor in soft tissues, often in the extremities. 

“Adults with metastatic synovial sarcoma, a life-threatening form of cancer, often face limited treatment options in addition to the risk of cancer spread or recurrence,” Nicole Verdun, MD, director of the Office of Therapeutic Products in the FDA’s Center for Biologics Evaluation and Research, said in the agency press release announcing the approval. “Today’s approval represents a significant milestone in the development of an innovative, safe and effective therapy for patients with this rare but potentially fatal disease.”

T-cell receptor therapy, like chimeric antigen receptor (CAR) T-cell (CAR-T) therapy, involves altering patient T cells to fight cancer. While CAR-T therapy inserts an artificial receptor to target a specific surface protein on cancer cells, the T-cell receptor therapy modifies existing receptors to recognize an array of antigens on the surface of cancer cells — a promising strategy for targeting solid tumors. 

The accelerated approval of afami-cel was based on the phase 2 SPEARHEAD-1 trial in 44 patients with synovial sarcoma who received a single infusion of the therapy. The trial had enrolled 52 patients, but 8 did not receive afami-cel, including 3 who died and 1 who withdrew. 

According to the FDA announcement, the overall response rate was 43.2%, with a median time to response of 4.9 weeks. The median duration of response was 6 months (95% CI, 4.6 months to not reached). Among patients who responded, 39% had a duration of response of 12 months or longer.

“These results suggest that a one-time treatment with afami-cel has the potential to extend life while allowing responders to go off chemotherapy,” said lead investigator Sandra D’Angelo, MD, a sarcoma specialist at Memorial Sloan Kettering Cancer Center in New York City, in a company press release.

The prescribing information includes a boxed warning for serious or fatal cytokine release syndrome.

The most common nonlaboratory adverse reactions, occurring in at least 20% of patients, included cytokine release syndrome, nausea, vomiting, fatigue, infections, pyrexia, constipation, dyspnea, tachycardia, hypotension, diarrhea, and edema. The most common grade 3 or 4 laboratory abnormalities, occurring in at least 20% of patients, included decreased lymphocyte count, neutrophil count, white cell blood count, red blood cell, and platelet count.

The recommended dose is between 2.68x109 to 10x109 MAGE-A4 T-cell receptor–positive T-cells. The FDA notice specifies not using a leukodepleting filter or prophylactic systemic corticosteroids.

The list price for the one-time therapy is $727,000, according to Fierce Pharma.

FDA Expands Dostarlimab-gxly Approval for Endometrial Cancer

Article Type
Changed
Fri, 08/02/2024 - 15:41

The US Food and Drug Administration (FDA) has expanded the approval of dostarlimab-gxly (Jemperli, GSK) in conjunction with carboplatin and paclitaxel, followed by single-agent dostarlimab-gxly, for adults with primary advanced or recurrent endometrial cancer.

Prior FDA approval of the combination was granted for adults with primary advanced or recurrent endometrial cancer that was mismatch repair deficient (dMMR) or microsatellite instability–high (MSI-H).

The expanded approval, granted following a priority review, was based on efficacy and safety demonstrated in the randomized, controlled, multicenter RUBY trial, which included 494 patients who were randomized to receive the dostarlimab-gxly regimen or placebo plus carboplatin and paclitaxel, followed by placebo.

Researchers observed a significant improvement in median overall survival with treatment vs placebo in the overall population — 44.6 vs 28.2 months, respectively (hazard ratio [HR], 0.69). Median progression-free survival was also significantly better in the treatment vs placebo group — 11.8 vs 7.9 months, respectively (HR, 0.64).

“Today’s expanded approval will offer even more patients the opportunity for improved outcomes,” Matthew Powell, MD, of Washington University School of Medicine, and principal investigator on the RUBY trial, said in a press release. “This is the only immuno-oncology treatment regimen that has shown a statistically significant overall survival benefit for the full patient population, which is a meaningful step forward in treating this challenging cancer.”

Adverse reactions occurring in at least 20% of patients receiving dostarlimab-gxly include anemia, increased creatinine levels, peripheral neuropathy, decreased white blood cell counts, fatigue, nausea, alopecia, low platelet counts, increased glucose levels, lymphopenia, neutropenia, liver function test abnormalities, arthralgia, rash, constipation, diarrhea, decreased albumin levels, abdominal pain, dyspnea, decreased appetite, increased amylase levels, urinary tract infection, and vomiting. Immune-mediated adverse reactions with dostarlimab-gxly were similar to those previously reported.

The recommended dostarlimab-gxly dose, according to the full prescribing information, is 500 mg every 3 weeks for six cycles administered before carboplatin and paclitaxel if given on the same day, followed by 1000 mg monotherapy every 6 weeks until disease progression or unacceptable toxicity, or up to 3 years.

FDA Expands Darzalex Faspro Indication in Myeloma

Article Type
Changed
Fri, 08/02/2024 - 13:44

The US Food and Drug Administration (FDA) has approved daratumumab and hyaluronidase-fihj (Darzalex Faspro, Janssen Research and Development LLC) in combination with bortezomib, lenalidomide, and dexamethasone for induction and consolidation in transplant-eligible patients with newly diagnosed multiple myeloma.

Approval followed priority review and was based on efficacy and safety findings from the open-label PERSEUS trial involving 709 patients under age 70 years who were randomized to receive bortezomib, lenalidomide, and dexamethasone alone or in combination with daratumumab and hyaluronidase-fihj, according to the FDA

Compared with bortezomib, lenalidomide, and dexamethasone alone, the addition of daratumumab and hyaluronidase-fihj resulted in a 60% reduction in the risk for disease progression or death (hazard ratio, 0.40). Median progression-free survival was not reached in either group.

Adverse reactions occurring in ≥ 20% of patients were peripheral neuropathy, fatigue, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash. 

The recommended dosage for this indication is 1800 mg daratumumab and 30,000 units hyaluronidase, according to the full prescribing information.

Daratumumab and hyaluronidase-fihj, which was first approved in 2020, has a range of other indications in multiple myeloma.

Compared with bortezomib, lenalidomide, and dexamethasone alone, the addition of daratumumab and hyaluronidase-fihj resulted in a 60% reduction in the risk for disease progression or death (hazard ratio, 0.40). Median progression-free survival was not reached in either group.

Adverse reactions occurring in ≥ 20% of patients were peripheral neuropathy, fatigue, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash. 

The recommended dosage for this indication is 1800 mg daratumumab and 30,000 units hyaluronidase, according to the full prescribing information.

Daratumumab and hyaluronidase-fihj, which was first approved in 2020, has a range of other indications in multiple myeloma.

Compounded Semaglutide Overdoses Tied to Hospitalizations

Article Type
Changed
Fri, 08/23/2024 - 12:43

Patients are overdosing on compounded semaglutide due to errors in measuring and self-administering the drug and due to clinicians miscalculating doses that may differ from US Food and Drug Administration (FDA)–approved products.

The FDA published an alert on July 26 after receiving reports of dosing errors involving compounded semaglutide injectable products dispensed in multidose vials. Adverse events included gastrointestinal effects, fainting, dehydration, headache, gallstones, and acute pancreatitis. Some patients required hospitalization.
 

Why the Risks?

FDA-approved semaglutide injectable products are dosed in milligrams, have standard concentrations, and are currently only available in prefilled pens.

Compounded semaglutide products may differ from approved products in ways that contribute to potential errors — for example, in multidose vials and prefilled syringes. In addition, product concentrations may vary depending on the compounder, and even a single compounder may offer multiple concentrations of semaglutide.

Instructions for a compounded drug, if provided, may tell users to administer semaglutide injections in “units,” the volume of which may vary depending on the concentration — rather than in milligrams. In some instances, patients received syringes significantly larger than the prescribed volume.
 

Common Errors

The FDA has received reports related to patients mistakenly taking more than the prescribed dose from a multidose vial — sometimes 5-20 times more than the intended dose.

Several reports described clinicians incorrectly calculating the intended dose when converting from milligrams to units or milliliters. In one case, a patient couldn’t get clarity on dosing instructions from the telemedicine provider who prescribed the compounded semaglutide, leading the patient to search online for medical advice. This resulted in the patient taking five times the intended dose.

In another example, one clinician prescribed 20 units instead of two units, affecting three patients who, after receiving 10 times the intended dose, experienced nausea and vomiting.

Another clinician, who also takes semaglutide himself, tried to recalculate his own dose in units and ended up self-administering a dose 10 times higher than intended.

The FDA previously warned about potential risks from the use of compounded drugs during a shortage as is the case with semaglutide. While compounded drugs can “sometimes” be helpful, according to the agency, “compounded drugs pose a higher risk to patients than FDA-approved drugs because compounded drugs do not undergo FDA premarket review for safety, effectiveness, or quality.”

Breakthrough Blood Test for Colorectal Cancer Gets Green Light

Article Type
Changed
Wed, 08/07/2024 - 14:59

 

A breakthrough in medical testing now allows for colorectal cancer screening with just a simple blood test, promising a more accessible and less invasive way to catch the disease early. 

The FDA on July 29 approved the test, called Shield, which can accurately detect tumors in the colon or rectum about 87% of the time when the cancer is in treatable early stages. The approval was announced July 29 by the test’s maker, Guardant Health, and comes just months after promising clinical trial results were published in The New England Journal of Medicine.

Colorectal cancer is among the most common types of cancer diagnosed in the United States each year, along with being one of the leading causes of cancer deaths. The condition is treatable in early stages, but about 1 in 3 people don’t stay up to date on regular screenings, which should begin at age 45.

The simplicity of a blood test could make it more likely for people to be screened for and, ultimately, survive the disease. Other primary screening options include feces-based tests or colonoscopy. The 5-year survival rate for colorectal cancer is 64%.

While highly accurate at detecting DNA shed by tumors during treatable stages of colorectal cancer, the Shield test was not as effective at detecting precancerous areas of tissue, which are typically removed after being detected.

In its news release, Guardant Health officials said they anticipate the test to be covered under Medicare. The out-of-pocket cost for people whose insurance does not cover the test has not yet been announced. The test is expected to be available by next week, The New York Times reported.

If someone’s Shield test comes back positive, the person would then get more tests to confirm the result. Shield was shown in trials to have a 10% false positive rate.

“I was in for a routine physical, and my doctor asked when I had my last colonoscopy,” said John Gormly, a 77-year-old business executive in Newport Beach, California, according to a Guardant Health news release. “I said it’s been a long time, so he offered to give me the Shield blood test. A few days later, the result came back positive, so he referred me for a colonoscopy. It turned out I had stage II colon cancer. The tumor was removed, and I recovered very quickly. Thank God I had taken that blood test.”

FDA Calls AstraZeneca’s NSCLC Trial Design Into Question

Article Type
Changed
Wed, 07/31/2024 - 06:54

AstraZeneca was taken to task July 25 by the US Food and Drug Administration’s (FDA’s) Oncology Drug Advisory Committee (ODAC) for failing to heed an agency request about the design of a durvalumab (Imfinzi) trial for non–small cell lung cancer (NSCLC).

The trial in questionAEGEAN, investigated perioperative durvalumab for resectable NSCLC tumors across 802 patients. Patients without EGFR or ALK mutations were randomly assigned to receive durvalumab before surgery alongside platinum-containing chemotherapy and after surgery for a year as monotherapy or to receive chemotherapy and surgery alone. 

Patients receiving durvalumab demonstrated better event-free survival at 1 year (73.4% vs 64.5% without durvalumab) and a better pathologic complete response rate (17.2% vs 4.3% without). Currently, AstraZeneca is seeking to add the indication for durvalumab to those the agent already has

However, at the July 25 ODAC meeting, the committee explained that the AEGEAN trial design makes it impossible to tell whether patients benefited from durvalumab before surgery, after it, or at both points. 

Mounting evidence, including from AstraZeneca’s own studies, suggests that the benefit of immune checkpoint inhibitors, such as durvalumab, comes before surgery. That means prescribing durvalumab after surgery could be exposing patients to serious side effects and financial toxicity, with potentially no clinical benefit, “magnifying the risk of potential overtreatment,” the committee cautioned. 

When AEGEAN was being designed in 2018, FDA requested that AstraZeneca address the uncertainty surrounding when to use durvalumab by including separate neoadjuvant and adjuvant arms, or at least an arm where patients were treated with neoadjuvant durvalumab alone to compare with treatment both before and after surgery. 

The company didn’t follow through and, during the July 25 meeting, the committee wanted answers. “Why did you not comply with this?” asked ODAC committee acting chair Daniel Spratt, MD, a radiation oncologist at Case Western Reserve University in Cleveland, Ohio. 

AstraZeneca personnel explained that doing so would have required many more subjects, made the trial more expensive, and added about 2 years to AEGEAN.

One speaker noted that the company, which makes more than $4 billion a year on durvalumab, would have taken about 2 days to recoup that added cost. Others wondered whether the motive was to sell durvalumab for as long as possible across a patient’s course of treatment. 

Perhaps the biggest reason the company ignored the request is that “it wasn’t our understanding at that time that this was a barrier to approval,” an AstraZeneca regulatory affairs specialist said. 

To this end, the agency asked its advisory panel to vote on whether it should require — instead of simply request, as it did with AstraZeneca — companies to prove that patients need immunotherapy both before and after surgery in resectable NSCLC.

The 11-member panel voted unanimously that it should make this a requirement, and several members said it should do so in other cancers as well.

However, when the agency asked whether durvalumab’s resectable NSCLC approval should be delayed until AstraZeneca conducts a trial to answer the neoadjuvant vs adjuvant question, the panel members didn’t think so. 

The consensus was that because AEGEAN showed a decent benefit, patients and physicians should have it as an option, and approval shouldn’t be delayed. The panel said that the bigger question about the benefit of maintenance therapy should be left to future studies. 

FDA usually follows the advice of its advisory panels.

FDA Approves Deuruxolitinib for Severe Alopecia Areata in Adults

Article Type
Changed
Mon, 07/29/2024 - 15:10

The Food and Drug Administration (FDA) has approved the oral Janus kinase (JAK) inhibitor deuruxolitinib for the treatment of adults with severe alopecia areata.

The development, which was announced in a July 25, 2024, news release from the drug’s manufacturer Sun Pharma, is based on data from two pivotal randomized, double-blind, placebo-controlled phase 3 clinical trials: THRIVE-AA1 and THRIVE-AA2, which included 1220 adults with severe alopecia areata enrolled at sites in the United States, Canada, and Europe. Study participants had at least 50% scalp hair loss as measured by Severity of Alopecia Tool (SALT) for more than 6 months. Data were also collected from two open-label, long-term extension trials in which patients were eligible to enroll upon completion of the 24-week trials.

Deuruxolitinib, which comes in 8-mg tablets, is an oral selective inhibitor of JAK1 and JAK2 and is administered twice a day. According to the company press release, the average patient enrolled in the clinical trials had only 13% of their scalp hair coverage at baseline. At week 24, more than 30% of patients taking deuruxolitinib experiencing 80% or more scalp hair coverage (SALT score ≤ 20). Also, up to 25% of patients had almost all of their scalp hair back at 24 weeks (≥ 90% coverage).



In terms of safety, the data showed that 3.1% of patients who received deuruxolitinib 8 mg twice daily in the phase 2 dose-ranging study and phase 3 randomized placebo-controlled trials discontinued treatment owing to adverse reactions. The three most common adverse events in placebo-controlled trials were headache (12.4% vs 9.4% with placebo), acne (10% vs 4.3% with placebo), and nasopharyngitis (8.1% vs 6.7% with placebo). More than 100 people continued taking deuruxolitinib for more than 3 years.

Deuruxolitinib is the third treatment and third JAK inhibitor approved by the FDA for severe alopecia areata. Baricitinib (Olumiant) was approved in June 2022 for adults with alopecia areata, followed by ritlecitinib (Litfulo) approved in June 2023 for patients aged 12 years and older. 

In a statement from the National Alopecia Areata Foundation (NAAF), Nicole Friedland, NAAF’s president and CEO, said that “it is with tremendous excitement that we welcome the FDA’s approval of a third treatment for severe alopecia areata in as many years.”

The Food and Drug Administration (FDA) has approved the oral Janus kinase (JAK) inhibitor deuruxolitinib for the treatment of adults with severe alopecia areata.

The development, which was announced in a July 25, 2024, news release from the drug’s manufacturer Sun Pharma, is based on data from two pivotal randomized, double-blind, placebo-controlled phase 3 clinical trials: THRIVE-AA1 and THRIVE-AA2, which included 1220 adults with severe alopecia areata enrolled at sites in the United States, Canada, and Europe. Study participants had at least 50% scalp hair loss as measured by Severity of Alopecia Tool (SALT) for more than 6 months. Data were also collected from two open-label, long-term extension trials in which patients were eligible to enroll upon completion of the 24-week trials.

Two Soliris Biosimilars Approved for PNH in the US

The Food and Drug Administration (FDA) recently approved two biosimilars to Soliris for the treatment of two rare diseases — paroxysmal nocturnal hemoglobinuria (PNH), a debilitating and potentially deadly blood disorder, and atypical hemolytic uremic syndrome.

The first, Bkemv (eculizumab-aeeb, Amgen), was approved in May, and the second, Epysqli (eculizumab-aagh, Samsung Bioepis), was approved on July 22.

Soliris (eculizumab, Alexion) is an intravenous agent indicated for the treatment of PNH and atypical hemolytic uremic syndrome, as well as generalized myasthenia gravis and neuromyelitis optical spectrum disorder.

Both Bkemv and Epysqli are monoclonal antibodies that bind to complement protein C5 and have been approved previously in Europe. Availability for Bkemv in the United States will be delayed until March 1, 2025, under a patent settlement agreement between Alexion and Amgen.

The FDA approval for Bkemv was based on findings from the double-blind, active-controlled, phase 3 DAHLIA study showing similar efficacy, safety, and immunogenicity to Soliris in adults with PNH. The agents reduce the loss of red blood cells and, thus, the need for blood transfusion in patients with PNH.

The DAHLIA study included 42 adults with PNH who had previously received Soliris for at least 6 months. These patients were then randomized to receive Soliris or Bkemv in one of two sequences delivered across two treatment periods. For study period 1 (weeks 1-53), patients were randomized to either 900 mg of intravenous (IV) Bkemv or Soliris every 14 days for 52 weeks, and for study period 2, the patients crossed over to the other treatment for 26 weeks.

Comparable efficacy was observed in both the parallel and crossover comparisons, with geometric mean values for trough total and unbound concentrations of Bkemv and Soliris similar between the treatment groups at all time points tested. Control of intravascular hemolysis was measured by lactate dehydrogenase at week 27 for the parallel comparison and by time-adjusted area under the effect curve of lactate dehydrogenase from weeks 13 to 27, from weeks 39 to 53, and from weeks 65 to 79 for the crossover comparison.

The approval for Epysqli was on the basis of phase 3 trial findings, in which 50 patients with PNH were randomized to Epysqli or Soliris through week 26, after which the treatment was switched and provided until week 50. The findings showed a mean difference in lactate dehydrogenase level at week 26 between Epysqli and Soliris was 34.48 U/L, which fell within the predefined equivalence margin. The ratio of time-adjusted area under the effect curve of lactate dehydrogenase between the two was 1.08 — also within the predefined equivalence margin — indicating bioequivalence between the biosimilar and reference product.

Similar to Soliris, the prescribing information for Bkemv and Epysqli includes a boxed warning associated with an increased risk for serious meningococcal infections. Because of this risk, both biosimilars are only available under a Risk Evaluation and Mitigation Strategy program that prescribers are required to enroll in.

According to drugs.com, Soliris (10 mg/mL) IV solution comes to about $6878 for a supply of 30 milliliters; cost information for the biosimilars is not available yet.
