U.S. FDA Grants Full Approval of Kite’s Tecartus for Adult Patients with Relapsed or Refractory Mantle Cell Lymphoma

The U.S. Food and Drug Administration (FDA) has granted traditional (full) approval to Kite’s CAR T-cell therapy, Tecartus (brexucabtagene autoleucel), for adult patients with relapsed or refractory (R/R) mantle cell lymphoma (MCL). The full approval now includes efficacy, safety and pharmacokinetic data from Cohort 3 of the ZUMA-2 study in patients who are R/R after one or more lines of therapy and who are Bruton tyrosine kinase inhibitor (BTKi)-naïve.

Today’s action converts the R/R MCL indication to full approval based on the totality of evidence from ZUMA-2, including confirmatory data from Cohort 3, which demonstrated high response rates, durable efficacy outcomes and a manageable safety profile consistent with prior experience. This milestone fulfills Kite’s post-marketing requirement for verification and description of clinical benefit in a confirmatory trial under the FDA’s Accelerated Approval pathway for Tecartus in R/R MCL.

“The full approval of brexu-cel in relapsed or refractory mantle cell lymphoma, along with the inclusion of Cohort 3 data in the label, reinforces our confidence in the overall profile of brexu-cel,” said Michael Wang, M.D., ZUMA-2 Lead Investigator and Professor, Department of Lymphoma and Myeloma, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center. “The Cohort 3 results showed high response rates, including deep remissions, in patients who were Bruton tyrosine kinase inhibitor-naïve, with a manageable safety profile consistent with prior experience. These data provide important information to help guide treatment decisions in the relapsed or refractory setting for appropriate patients.”

MCL is a rare form of non-Hodgkin lymphoma (NHL) that arises from cells originating in the “mantle zone” of the lymph node and predominantly affects men over the age of 60. Approximately 33,000 people worldwide are diagnosed with MCL each year. MCL is highly aggressive following relapse, with many patients’ disease progressing following therapy.

“The full approval of Tecartus for adults with relapsed or refractory mantle cell lymphoma reflects meaningful progress,” said Gallia Levy, MD, PhD, Senior Vice President and Global Head of Development, Kite. “For those whose cancer has returned, the data support Tecartus as a second-line treatment option with the potential to deliver long-term remission.”

Data Supporting Full Approval of Tecartus in R/R MCL

ZUMA-2 is a single-arm, open-label, multicenter study evaluating Tecartus in adult patients with R/R MCL. Cohorts 1 and 2 evaluated Tecartus in patients who had previously received up to five lines of therapy including anthracycline- or bendamustine-containing chemotherapy, an anti-CD20 antibody and a BTKi. Cohort 3 evaluated Tecartus in patients who had received up to five prior lines of therapy and were BTKi-naïve. A total of 82 patients were treated in Cohorts 1 and 2, and 86 patients were treated in Cohort 3. The primary endpoint across the study was objective response rate (ORR) per the Lugano Classification (2014), as assessed by an Independent Radiologic Review Committee.

FDA Grants Accelerated Approval to Yuviwel (navepegritide) for Children with Achondroplasia

Ascendis Pharma A/S (Nasdaq: ASND) today announced that the U.S. Food & Drug Administration (FDA) has granted approval under the FDA’s Accelerated Approval Program for Yuviwel (navepegritide; developed as TransCon® CNP), the first and only once-weekly treatment indicated to increase linear growth in children 2 years of age and older with achondroplasia with open epiphyses and the only one to provide continuous systemic exposure to CNP over the weekly dosing interval. Continued approval for this indication, which was based on an improvement in annualized growth velocity (AGV), may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

• The first and only approved achondroplasia therapy to provide continuous systemic exposure to CNP over the weekly dosing interval
• Commercial availability expected during early part of Q2 2026
• Rare Pediatric Disease Priority Review Voucher granted in connection with approval

Achondroplasia is a rare genetic condition causing skeletal dysplasia and, for many affected individuals, an increased risk of muscular, neurological, and cardiorespiratory complications. Yuviwel is a prodrug of C-type natriuretic peptide (CNP) administered once weekly, designed to provide continuous exposure of active CNP to receptors on tissues throughout the body to counteract the overactive FGFR3 signaling in achondroplasia.

“The approval of once-weekly Yuviwel is a major step forward in the treatment of children with achondroplasia, giving physicians for the first time the option of prescribing a once-weekly medicine backed by compelling efficacy and excellent tolerability data from three randomized, double-blind, placebo-controlled clinical trials,” said Carlos A. Bacino, MD, FACMG, Professor of Molecular and Human Genetics, Baylor College of Medicine and Texas Children’s Hospital. “My goal is to help children and parents develop care plans tailored to their individual needs and objectives, and I look forward to adding Yuviwel to my discussions with them.”

“Little People of America, the largest national advocacy and support organization for people with dwarfism, is committed to ensuring that the voices of people with dwarfism remain central in conversations about research and medical options such as Yuviwel,” said the Board of Directors of Little People of America. “We champion dwarf and disability pride, advocate for inclusion and respect, and foster open dialogue across diverse perspectives. Our goal is to empower individuals and families to make healthcare decisions that reflect their own values and experiences, while pushing for research efforts and new treatment options such as this that could have the potential to support outcomes that truly matter to our community.”

The FDA based its approval of Yuviwel on their review of the clinical package for TransCon CNP submitted with the Company’s New Drug Application, which included safety and efficacy data from three randomized, double-blind, placebo-controlled clinical trials and up to three years of open-label extension data. The pivotal ApproaCH Trial data is available in JAMA Pediatrics.i

“We are confident in Yuviwel’s potential to transform the treatment of achondroplasia and are deeply grateful to patients, clinicians, and advocates for their many contributions to this important milestone,” said Jan Mikkelsen, President and Chief Executive Officer at Ascendis Pharma. “We have listened to advocacy groups for people with dwarfism to ensure we address what the community actually cares about. This reflects our ongoing commitment to pursue outcomes that patient communities have told us are important to them, and gives the achondroplasia community a new way to look at the promise of pharmacological treatment options.”

Ascendis expects to make Yuviwel available through prescribing physicians in the United States during the early part of the second quarter of 2026. Ascendis plans to offer a suite of patient services for Yuviwel through its U.S. Ascendis Signature Access Program (A.S.A.P.), including support navigating the treatment journey and financial assistance programs for eligible patients.

With this approval, the FDA also issued a Rare Pediatric Disease Priority Review Voucher (PRV), which confers priority review to a subsequent drug application that would not otherwise qualify for priority review. This program is designed to encourage development of new drugs and biologics for the prevention or treatment of rare pediatric diseases.

FDA Grants Accelerated Approval to Zegfrovy (sunvozertinib) for Non-Small Cell Lung Cancer with EGFR Exon 20 Insertion Mutations

Dizal (SSE:688192), a biopharmaceutical company committed to developing novel medicines for the treatment of cancer and immunological diseases, announced  the U.S. Food and Drug Administration (FDA) approval of  Zegfrovy (sunvozertinib) for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations (exon20ins), as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.

Zegfrovy, which has received Priority Review and Breakthrough Therapy Designation from the FDA, is the only approved targeted oral treatment for NSCLC with EGFR exon20ins. This indication is approved under Accelerated Approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

“We are proud to have developed Zegfrovy, a first-in-class oral therapy that offers a more effective treatment option with enhanced safety and ease of administration for NSCLC patients with EGFR exon20ins,” said Dr. Xiaolin Zhang, CEO of Dizal. “The accelerated approval of Zegfrovy marks a significant milestone that underscores our commitment to developing groundbreaking new medicines for patients with high unmet medical needs around the world.”

Zegfrovy is an oral, irreversible EGFR inhibitor with uniquely designed molecular structure targeting a wide spectrum of EGFR mutations with wild-type EGFR selectivity. In August 2023, Zegfrovy received accelerated approval in China. Today’s FDA approval follows Breakthrough Therapy Designation and Priority Review granted by both the U.S. FDA and the Center for Drug Evaluation (CDE)of China’s National Medical Products Administration (NMPA).

The FDA approval is supported by data from the multinational pivotal study WU-KONG1 Part B (WU-KONG1B), aiming to investigate the efficacy and safety of Zegfrovy in relapsed or refractory NSCLC with EGFR exon20ins. The study results were featured as an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting and were recently published in the Journal of Clinical Oncology.

“As the world's only approved targeted oral therapy for EGFR exon20ins NSCLC, Zegfrovy has expanded the treatment paradigm in this therapeutic area that has long lacked convenient and effective treatment options,” said Pasi A. Jänne, MD, PhD, Dana-Farber Cancer Institute of Harvard Medical School and lead principal investigator of WU-KONG1B. “Research findings from WU-KONG1B have demonstrated Zegfrovy’s significant therapeutic effects with consistent efficacy across both Asian and non-Asian patient populations. Its convenient once-daily oral dosing substantially improves administration convenience and patient adherence, which is an increasingly critical factor as lung cancer care shifts toward chronic disease management. The U.S. approval of Zegfrovy® marks a landmark in scientific advancement and represents a meaningful milestone in addressing the long-standing unmet medical needs of this underserved patient population."

“Zegfrovy has demonstrated breakthrough therapeutic value in the treatment of EGFR exon20ins NSCLC, as shown in a rigorous multinational clinical trial. Its potent antitumor activity, manageable safety profile, and convenient oral administration position it as an optimal treatment option in clinical practice,” said Prof. James Chih-Hsin Yang, MD, PhD, National Taiwan University Cancer Center Hospital and the Co-lead principal investigator of WU-KONG1B. “The approval of Zegfrovy in major global markets not only offers new hope for patients, but also reinforces our commitment to patient-centered research and the continued advancement of precision medicine in lung cancer."

“In NSCLC, EGFR exon20ins represent the third most common type of EGFR mutation. EGFR exon20ins are particularly challenging to treat due to their unique spatial conformation, diverse mutation subtypes, and high heterogeneity. As a result, patients face a poor prognosis and limited treatment options,” said Prof. Mengzhao Wang, MD, PhD, lead principal investigator of the China-based pivotal study WU-KONG6 of Zegfrovy and principal investigator of WU-KONG1B at Peking Union Medical College Hospital, “The results of the WU-KONG6 study demonstrated Zegfrovy’s clinical benefit superior to current options and lead to the drug’s approval in China. The U.S. approval of Zegfrovy will enable more patients around the world to benefit from this drug.”

The FDA simultaneously approved Thermo Fisher Scientific’s Oncomine™ Dx Express Test as a next-generation sequencing (NGS) companion diagnostic (CDx) for Zegfrovy to identify NSCLC patients with EGFR Exon20 insertions. NGS testing is recognized as a critical technology in cancer genomic profiling, facilitating the rapid and precise detection of DNA mutations in tumor cells. Combined with the Ion Torrent™ Genexus™ Dx System, the test delivers NGS results in as little as 24 hours to help inform more timely treatment decisions in patients with EGFR exon20ins NSCLC.

Additionally, Dizal has completed enrollment for its multinational phase III pivotal WU-KONG28 study, evaluating Zegfrovy versus platinum-based doublet chemotherapies in treatment naïve NSCLC patients with EGFR exon20ins across 16 countries and regions. At the 2023 European Society for Medical Oncology (ESMO) Annual Meeting, Dizal reported that Zegfrovy, as a single oral agent, achieved a confirmed objective response rate (ORR) of 78.6% and a median progression-free survival (mPFS) of 12.4 months in the first-line setting. With its potent antitumor activity and favorable safety profile, Zegfrovy demonstrated strong potential as an optimalfirst-line treatment for patients with EGFR exon20ins NSCLC.

FDA Grants Accelerated Approval for Vanrafia (atrasentan) for Proteinuria Reduction in Primary IgA Nephropathy

Novartis  announced the US Food and Drug Administration (FDA)  accelerated approval for Vanrafia® (atrasentan), a potent and selective endothelin A (ETA) receptor antagonist, for the reduction of proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk of rapid disease progression. This is generally defined as a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/g1. Vanrafia is a once-daily, non-steroidal, oral treatment that can be added onto supportive care, including a renin-angiotensin system (RAS) inhibitor with or without a sodium-glucose co-transporter-2 (SGLT2) inhibitor.

Vanrafia was granted accelerated approval based on a prespecified interim analysis of the Phase III ALIGN study measuring the reduction of proteinuria at 36 weeks compared to placebo1. It has not been established whether Vanrafia slows kidney function decline in patients with IgAN. The continued approval of Vanrafia may be contingent upon the verification of clinical benefit from the ongoing Phase III ALIGN study evaluating whether Vanrafia slows disease progression as measured by estimated glomerular filtration rate (eGFR) decline at week 1361. The eGFR data are expected in 2026 and intended to support traditional FDA approval.

“Today’s approval marks an important milestone for people living with IgA nephropathy, offering a new option that can be seamlessly integrated into their existing treatment plan, with no REMS requirement,” said Richard Lafayette, M.D., F.A.C.P., Professor of Medicine, Nephrology and Director of the Glomerular Disease Center at Stanford University Medical Center, and Vanrafia ALIGN Study Investigator and Steering Committee Member. “Vanrafia is a selective ETA receptor antagonist that effectively reduces proteinuria, a major risk factor in IgAN. Taking early, decisive action is critical to help improve outcomes for these patients who too often progress toward kidney failure.”

IgAN is a progressive, rare kidney disease in which the immune system attacks the kidneys, often causing glomerular inflammation and proteinuria10. With almost 13 out of every million people in the US diagnosed per year, it is one of the most common autoimmune kidney diseases, and each person’s journey is unique11,12. Up to 50% of IgAN patients with persistent proteinuria progress to kidney failure within 10 to 20 years of diagnosis, often requiring maintenance dialysis and/or kidney transplantation3-10, and response to treatment can vary12,13. Effective, targeted therapies with different mechanisms of action can help physicians select the most appropriate treatment for patients.

FDA Grants Accelerated Approval for Rezdiffra (resmetirom) for the Treatment of Patients with Noncirrhotic Nonalcoholic Steatohepatitis (NASH)

Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL), a biopharmaceutical company focused on delivering novel therapeutics for nonalcoholic steatohepatitis (NASH),  announced the U.S. Food and Drug Administration (FDA)  accelerated approval for Rezdiffra (resmetirom) in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Continued approval for this indication may be contingent upon verification and description of clinical benefit in ongoing confirmatory trials.

Bill Sibold, Chief Executive Officer of Madrigal, stated, “NASH with moderate to advanced liver fibrosis is a serious and progressive liver disease that, until now, has not had an FDA-approved therapy. The accelerated approval of Rezdiffra is a culmination of more than 15 years of research from our founder Dr. Becky Taub and a small R&D team that took on one of the biggest challenges in drug development. This is a historic moment for the NASH field and represents the best of what our industry is capable of. We’re excited to deliver Rezdiffra to patients in need.”

Becky Taub, M.D., the Founder, Chief Medical Officer and President of Research & Development of Madrigal, stated, “Madrigal would like to thank the many patients who made the accelerated approval of Rezdiffra possible by participating in our clinical studies. We believe Rezdiffra will change the treatment paradigm for NASH with moderate to advanced liver fibrosis, giving physicians a liver-directed therapy to help improve fibrosis and resolve NASH before their patients progress to cirrhosis.”

Wayne Eskridge, Co-Founder and Chief Executive Officer of the Fatty Liver Foundation, stated, “This is a day of celebration for patients with NASH who have been waiting many years for the first approved therapy. I believe this approval milestone will bring new energy and momentum to the NASH community, accelerating our efforts to improve disease education, build care pathways, and expand investment in NASH research.”

Rezdiffra is a once-daily, oral THR-β agonist designed to target key underlying causes of NASH. The accelerated approval of Rezdiffra was based on results from the Phase 3 MAESTRO-NASH trial, which was recently published in the New England Journal of Medicine. MAESTRO-NASH is an ongoing pivotal, multicenter, randomized, double-blind, placebo-controlled trial that enrolled 1,759 patients with biopsy-confirmed NASH. Following 52 weeks of treatment, both 100 mg and 80 mg doses of Rezdiffra demonstrated statistically significant improvement compared to placebo on two primary endpoints: NASH resolution (including a reduction in the nonalcoholic fatty liver disease [NAFLD] activity score by ≥2 points) with no worsening of fibrosis, and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. Fibrosis improvement and NASH resolution were consistent regardless of age, gender, type 2 diabetes status, or fibrosis stage.

The Rezdiffra prescribing information does not include a liver biopsy requirement for diagnosis. The recommended dosage of Rezdiffra is based on actual body weight. For patients weighing <100 kg (220 lbs.), the recommended dosage is 80 mg orally once daily. For patients weighing ≥100 kg (220 lbs.), the recommended dosage is 100 mg orally once daily.

Stephen Harrison, M.D., Chairman for both Pinnacle Clinical Research and Summit Clinical Research, San Antonio, Texas, Visiting Professor of Hepatology, Oxford University, and lead Principal Investigator of the MAESTRO studies, commented, “The approval of the first medication for NASH is a true game-changer for healthcare providers, the research community and, most importantly, patients living with this serious liver condition. Based on the robust efficacy and safety data generated in two large Phase 3 MAESTRO studies, I believe Rezdiffra will become the foundational therapy for patients with NASH with moderate to advanced liver fibrosis.”

Dr. Harrison continued, “Importantly, we continue to study Rezdiffra to determine if the positive results observed in the MAESTRO studies will lead to reduced risk of progression to cirrhosis, liver failure, need for liver transplant and premature mortality.”

MAESTRO-NASH remains ongoing as an outcomes study designed to generate confirmatory data that, if positive, will help verify clinical benefit and may support full approval. A second ongoing outcomes trial is evaluating progression to liver decompensation events in patients with well-compensated NASH cirrhosis treated with Rezdiffra versus placebo.

Rezdiffra should not be used in patients with decompensated cirrhosis. The most common adverse reactions reported in patients treated with Rezdiffra included diarrhea, nausea, pruritis, abdominal pain, vomiting, constipation, and dizziness. Diarrhea and nausea typically began early in treatment initiation and were mild to moderate in severity. A separate, noninvasive Phase 3 trial, MAESTRO-NAFLD-1, evaluated the safety and tolerability of Rezdiffra and contributed to the safety database supporting regulatory benefit-risk assessment.

Rezdiffra is expected to be available to patients in the U.S. in April and will be distributed through a limited specialty pharmacy network. Madrigal is committed to helping appropriate patients who may benefit from Rezdiffra access the medication through the Madrigal Patient Support program. This program is designed to help patients navigate insurance and affordability challenges and provide co-pay support for eligible patients. Madrigal has also established a patient assistance program (PAP) to help patients with no insurance access Rezdiffra.

Phase 3 MAESTRO-NASH Trial Results

MAESTRO-NASH is an ongoing Phase 3 trial that enrolled 1759 patients with biopsy-confirmed NASH. Patients were randomly assigned in a 1:1:1 ratio to receive once-daily Rezdiffra at a dose of 80 mg or 100 mg or placebo. The two primary endpoints at week 52 were NASH resolution with no worsening of fibrosis and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. The key secondary endpoint was the percent change from baseline in LDL cholesterol at week 24.

Rezdiffra achieved both primary endpoints and the key secondary endpoint of the MAESTRO-NASH trial. Additionally, Rezdiffra improved liver enzymes, fibrosis biomarkers and imaging tests as compared with placebo. The primary results of the trial were published in the New England Journal of Medicine in February 2024.

Patients enrolled in the MAESTRO-NASH trial continue on therapy after the initial 52-week treatment period for up to 54 months to accrue and measure hepatic clinical outcome events including progression to cirrhosis on biopsy and hepatic decompensation events, as well as all-cause mortality. The 54-month outcomes portion of the trial is designed to generate confirmatory data that, if positive, will help verify Rezdiffra’s clinical benefit and may support full approval.
