Norgine B.V. has announced the submission of marketing authorization applications for eflornithine (difluoromethylornithine, DFMO) in high-risk neuroblastoma (HRNB) to regulatory agencies in Australia, Switzerland, and the United Kingdom. The submissions, made on April 10, 2024, are being pursued via Project Orbis, an initiative designed to accelerate the global availability of innovative cancer therapies.
The application seeks to introduce eflornithine as a maintenance therapy for HRNB patients who have already undergone standard treatments. This regulatory step follows the U.S. Food and Drug Administration (FDA) approval of eflornithine on December 13, 2023, for the same indication.
Clinical Data Supporting Eflornithine
The FDA's approval of eflornithine was based on data from a clinical trial comparing outcomes from Study 3b (NCT02395666) and Study ANBL0032 (NCT00026312). The results indicated that eflornithine significantly improved event-free survival and overall survival compared to patients treated with standard of care alone.
The Need for New HRNB Therapies
HRNB remains a challenging disease, with approximately 30% of patients relapsing after initial treatment. Relapsed HRNB carries a poor prognosis, with long-term survival rates estimated as low as 15%. Currently, outside of the United States, there are limited approved options for sustaining remission in HRNB patients following standard of care.
Norgine's Commitment
Dr. David Gillen, Chief Medical Officer at Norgine, stated that these submissions via Project Orbis are a crucial step in securing additional treatment options for HRNB patients, highlighting the company's commitment to addressing this unmet medical need.
