The royalties for Pfizer’s Ruxience biosimilar, which has achieved a near 25% penetration rate in the US market, are to fall into the hands of another party following an agreement by original holder Aptevo Therapeutics. Teva’s Truxima is reported to be market leader in the US.
Pfizer has received European Commission approval for the firm’s Ruxience biosimilar to Roche’s MabThera brand, including as a treatment for rheumatoid arthritis, opening the door to a three-way biosimilar fight in the European Union.
With an eye on moving to market its broad pipeline of innovative brands, Pfizer has cut development of five early-stage biosimilar assets, in a decision that will affect 150 staff. The move is not reflective of Pfizer's overall commitment to biosimilars, the US-based company maintains.
