About Medincell

Medincell is a clinical- and commercial-stage innovation-driven biopharmaceutical company developing and licensing long-acting injectable treatments across multiple therapeutic areas. Our innovative treatments are designed to ensure adherence to medical prescriptions, enhance the effectiveness and accessibility of medicines, and reduce their environmental impact.

These treatments combine active pharmaceutical ingredients with our proprietary BEPO ® / BEPO® Star technologies, which enables controlled drug delivery at therapeutic levels for several days, weeks, or months following a subcutaneous or local injection of a small, fully bioresorbable depot.

Risperidone LAI was the first treatment based on BEPO® technology to receive FDA approval, initially for schizophrenia in April 2023, and subsequently for Bipolar I Disorder in October 2025. It is marketed in the United States by Teva under the brand name UZEDY®.

A New Drug Application (NDA) for Olanzapine LAI as a once-monthly treatment for schizophrenia in adults was submitted to the U.S. FDA in December 2025 by Medincell’s partner, Teva. U.S. FDA accepted Teva’s New NDA for Olanzapine LAI on February 20, 2026. A European Marketing Authorization Application (MAA) was also accepted by EMA in May 2026.

Medincell’s investigational pipeline includes numerous innovative therapeutic candidates in various stages of development, from formulation to Phase 3 clinical trials. We collaborate with leading pharmaceutical companies and foundations to advance global health through new treatment options.

Headquartered in Montpellier, France, Medincell employs over 150 people representing more than 27 nationalities.
