Results from a REFLECTIONS B538-02 trial with Pfizer’s investigational Humira (adalimumab) biosimilar, PF-06410293, showed that the drug met its primary endpoint, and demonstrated similar efficacy to its reference product. PF-06410293 is being evaluated in combination with methotrexate as a treatment for moderate to severe rheumatoid arthritis, the company said in a Jan. 5, 2017 announcement.
PF-06410293 is Pfizer’s second proposed inflammation biosimilar. The company’s pipeline consists of eight biosimilar molecules in mid- to late-stage development. Pfizer also said it has several other biosimilar molecules currently in early-stage development. Pfizer will likely face competition in the Humira biosimilar market. FDA approved the first biosimilar to Humira, Amjevita (adalimumab-atto), marketed by Amgen in the United States, in late September 2016.
