Biogen to return Fampyra rights to Acorda

12 January 2024

As generic competition has eroded sales of Fampyra (fampridine), US biotech major Biogen (Nasdaq: BIIB) has decided to return its ex-USA rights to the multiple sclerosis treatment to licensor Acorda Therapeutics (Nasdaq: ACOR), with effect from January 1, 2025. Acorda’s shares were down 2.8% at $15.90 in pre-market activity.

Fampyra is indicated in the European Union and other territories throughout the world for the improvement of walking in adults with multiple sclerosis (MS) with walking disability. Acorda markets the medication as Amprya (dalfampridine) in the USA.

Acorda and Biogen are working together toward a transition for Acorda to commercialize and supply Fampyra for the great majority of people with MS outside the USA currently being served. Acorda plans to assume commercialization responsibilities as soon as possible during 2024 as marketing authorization transfers and distribution arrangements are finalized for each territory.
