– New PDUFA action date of December 26, 2024 allows FDA additional time to complete their review –
WALTHAM, Mass., July 29, 2024 /PRNewswire/ -- Syndax Pharmaceuticals (Nasdaq: SNDX), a clinical stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today announced that the U.S. Food and Drug Administration (FDA) has extended the Prescription Drug User Fee Act (PDUFA) action date for the New Drug Application (NDA) for revumenib for the treatment of adults and pediatric patients with relapsed or refractory (R/R) KMT2Ar acute leukemia.
The FDA notified Syndax on July 26, 2024 that they required additional time to conduct a full review of supplemental information provided to the FDA in response to their requests. The submission of additional information to the FDA was determined to constitute a Major Amendment to the NDA and resulted in a standard three-month extension to the original PDUFA action date of September 26, 2024. No additional trials or manufacturing information have been requested by the FDA.
“Revumenib, upon approval, will be the first drug indicated to treat patients with KMT2A-rearranged acute leukemia, a population with significant unmet need,” said Michael A. Metzger, Chief Executive Officer. “We are confident that the data from the AUGMENT-101 trial, as well as the additional information provided to the FDA, support approval and continue to demonstrate the meaningful benefit revumenib brings to patients with this devastating disease. We look forward to continuing our engagement with the FDA as they complete their review of the NDA by December 26, 2024.”
The NDA for revumenib was granted Priority Review and is being reviewed under the FDA’s Real-Time Oncology Review (RTOR) program. The FDA previously granted Breakthrough Therapy, Fast Track and Orphan Drug designations for revumenib.
About Revumenib
Revumenib is a potent, selective, small molecule inhibitor of the menin-KMT2A binding interaction that is being developed for the treatment of KMT2A-rearranged (KMT2Ar), also known as mixed lineage leukemia rearranged or MLLr, acute leukemias including ALL and AML, and mutant nucleophosmin (mNPM1) AML. Positive topline results from the Phase 2 AUGMENT-101 trial in R/R KMT2Ar acute leukemia showing the trial met its primary endpoint were presented at the 65th American Society of Hematology Annual Meeting, and data from the Phase 1 portion of AUGMENT-101 in acute leukemia was published in Nature. Revumenib was granted Orphan Drug Designation for the treatment of AML and ALL by the FDA and for the treatment of AML by the European Commission, and Fast Track designation by the FDA for the treatment of adult and pediatric patients with R/R acute leukemias harboring a KMT2A rearrangement or NPM1 mutation. Revumenib was granted Breakthrough Therapy Designation by the FDA for the treatment of adult and pediatric patients with R/R acute leukemia harboring a KMT2A rearrangement.About the Real-Time Oncology Review Program (RTOR)
RTOR provides a more efficient review process for oncology drugs to ensure that safe and effective treatments are available to patients as early as possible, while improving review quality and engaging in early iterative communication with the applicant. Specifically, it allows for close engagement between the sponsor and the FDA throughout the submission process and it enables the FDA to review individual sections of modules of a drug application rather than requiring the submission of complete modules or a complete application prior to initiating review.
