Data subsets to be shared today in plenary oral presentations at the 2023 Society for Neuro-Oncology Annual Meeting
BRISBANE, Calif., Nov. 17, 2023 (GLOBE NEWSWIRE) -- Day One Biopharmaceuticals (Nasdaq: DAWN) (“Day One” or the “Company”), a clinical-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, today announced the publication of the registrational Phase 2 FIREFLY-1 trial results evaluating the investigational agent tovorafenib in patients with BRAF-altered, relapsed or progressive pediatric low-grade glioma (pLGG) in Nature Medicine. Subsets of the data will also be presented today in two oral plenary presentations at the 2023 Society for Neuro-Oncology (SNO) Annual Meeting in Vancouver, Canada.
“The study results published in Nature Medicine demonstrate promising evidence with respect to the the impact of tovorafenib for children and young adults with BRAF-altered relapsed or progressive pLGG, a debilitating form of brain tumor that currently has no approved systemic therapies,” said Dr. Samuel Blackman, co-founder and head of research and development, Day One. “We look forward to continued development of tovorafenib.”

A New Drug Application for tovorafenib monotherapy in BRAF-altered relapsed or progressive pLGG is currently under priority review by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act target action date of April 30, 2024. In addition to FIREFLY-1, the Phase 3 FIREFLY-2/LOGGIC randomized clinical trial is evaluating tovorafenib frontline therapy for patients newly diagnosed with pLGG.
About Tovorafenib
Tovorafenib is an investigational, oral, brain-penetrant, highly-selective type II RAF kinase inhibitor designed to target a key enzyme in the MAPK signaling pathway, which is being investigated in primary brain tumors or brain metastases of solid tumors. Tovorafenib has been studied in over 350 patients to date and is currently under evaluation in two pivotal clinical trials for pLGG. Tovorafenib is also being evaluated as a combination therapy for adolescent and adult patient populations with recurrent or progressive solid tumors with MAPK pathway aberrations (FIRELIGHT-1).
Tovorafenib has been granted Breakthrough Therapy and Rare Pediatric Disease designations by the FDA for the treatment of patients with pLGG harboring an activating RAF alteration. Tovorafenib has also received Orphan Drug designation from the FDA for the treatment of malignant glioma, and from the European Commission for the treatment of glioma.
