Biomedica was originally appointed as a distributor for AGAMREE® in October 2025. Under the expanded agreement, Biomedica will be responsible for distribution in the additional five markets, while Santhera will continue to receive a percentage of net sales in line with the terms of the original agreement. Approximately 2,000 patients are living with DMD across these additional countries, where treatment options have historically been largely limited to standard corticosteroids. The expanded agreement creates a pathway to making AGAMREE® available to these patients. Marc Clausse, Chief Commercial Officer of Santhera, said: “Biomedica’s proven expertise in the region makes them a natural partner for expansion into these additional markets, where treatment options remain limited. This agreement represents another important step in our international partnership strategy and reinforces our continued commitment to making AGAMREE® available to patients wherever they live. We look forward to continuing our collaboration with Biomedica and exploring opportunities to expand into additional markets in the future.” Oleg Parosin, Founder and Chief Executive Officer of Biomedica, added: “We are excited to broaden our partnership with Santhera. Leveraging our infrastructure and experience bringing innovative rare-disease therapies to patients across the CIS and Caucasus, we are well positioned to deliver AGAMREE® reliably in these five new markets and support families living with DMD.” About Santhera Santhera Pharmaceuticals (SIX: SANN) is a Swiss specialty pharmaceutical company focused on the development and commercialization of innovative medicines for rare neuromuscular diseases with high unmet medical need.
