Day One’s OJEMDA™ (tovorafenib) received U.S. Food and Drug Administration (FDA) Accelerated Approval for patients 6 months of age and older for the treatment of relapsed or refractory pediatric low-grade glioma (pLGG) harboring a BRAF fusion or rearrangement, or BRAF V600 mutation.

FDA approval of OJEMDA means that OJEMDA is now available for prescription by health care professionals in the United States.

The approval of OJEMDA ushers in a new day for children living with pLGG, and we are pleased that we can deliver the first and only targeted medicine for both BRAF fusions and mutations, for children living with relapsed or refractory pLGG,  the most common form of pediatric brain cancer,” said Jeremy Bender, Ph.D., chief executive officer of Day One. “We are grateful to the pLGG community, including patients and their families, clinicians, and advocacy groups, for their collaboration and support as we close the innovation gap for children with cancer waiting for new treatments.

To support the patient community, we are pleased to announce EveryDay Support From Day One™, a comprehensive program that offers personalized services for OJEMDA patients and their care teams. We are offering a variety of services and financial assistance programs to help eligible patients with coverage and affordability. EveryDay Support From Day One can help patients manage the process, from initiating and maintaining coverage, to helping with affordability throughout the patient’s treatment journey. Services include shipping medication to patients’ homes, and ongoing prescription and refill support. Caregivers and healthcare providers can visit www.everydaysupport.com for more information.

On behalf of everyone at Day One, we thank the patients for their participation in the FIREFLY-1 trial and their families, without whom this advancement of a new approved targeted therapy for pLGG would not be possible. We also thank the pediatric cancer non-profit and patient advocacy community for your partnership and support as we move forward in developing potential new therapies for children with cancer.

Day One announced that the U.S., Food and Drug Administration (FDA) accepted Day One’s New Drug Application (NDA) for tovorafenib as a monotherapy in relapsed or progressive pediatric low-grade glioma (pLGG). The NDA is based on results from FIREFLY-1, the open-label, pivotal Phase 2 trial evaluating tovorafenib as a once-weekly monotherapy in patients aged 6 months to 25 years with relapsed or progressive pLGG.

FDA acceptance of the NDA means that the FDA will now review the application for potential approval of tovorafenib for sale and marketing in the U.S.

Additionally, with Day One’s NDA, the FDA has granted priority review and assigned a Prescription Drug User Fee Act (PDUFA) target action date of April 30, 2024.

Tovorafenib is an investigational medicine. The safety and efficacy of tovorafenib has not been established. There is no guarantee that tovorafenib will receive health authority approval or become commercially available in any country for the uses being investigated.
