Jun 25, 2020

Aptevo Therapeutics announces it will receive quarterly “low single digit” fixed royalty payments from Pfizer (Wyeth) for 7 years from the first launch of Ruxience® (biosimilar rituximab). The original royalty agreement was signed by Trubion Pharmaceuticals which was then acquired by Aptevo’s spin-off Emergent BioSolutions, and Wyeth, in 2016. The royalty is applied to net sales in the US, EU and Japan.
