Pfizer announces positive top-line results from the comparative REFLECTIONS B7391003 study for PF-06439535, a potential biosimilar to Avastin® (bevacizumab)

PfizerPfizer Inc. (NYSE:PFE) has announced that the REFLECTIONS B7391003 study, a comparative, confirmatory safety and efficacy study of PF-06439535 versus Avastin®(1) (bevacizumab), met its primary objective. PF-06439535 is being developed by Pfizer as a potential biosimilar to Avastin.

The trial demonstrated equivalence in the primary endpoint of objective response rate (ORR) of PF-06439535 versus Avastin, taken in combination with carboplatin/paclitaxel, for the first line treatment of patients with advanced non-squamous non-small cell lung cancer (NSCLC).

"We are encouraged by this data, and its importance in helping to advance physician confidence in, and understanding of, the potential value of biosimilar medicines for cancer patients around the world," said Salomon Azoulay, MD, Senior Vice President, Chief Medical Officer, Pfizer Essential Health. "As Pfizer’s second proposed oncology monoclonal antibody biosimilar to achieve positive top line data results, we continue to focus on and commit to advancing our pipeline of proposed biosimilars, with the goal of expanding patient access to these important therapeutic options."

This latest data announcement represents Pfizer’s second proposed oncology biosimilar and the fourth proposed biosimilar pipeline molecule to report positive top-line results within the past year. The Pfizer biosimilars pipeline consists of eight distinct biosimilar molecules in mid to late stage development, and several others in early stage development.

About the REFLECTIONS B7391003 Study
REFLECTIONS B7391003 is a comparative, randomized, double blind, clinical trial [N=719] evaluating the efficacy, safety, pharmacokinetics (PK) and immunogenicity of PF-06439535 (a potential biosimilar to Avastin® [bevacizumab]) in combination with carboplatin/paclitaxel versus Avastin in combination with carboplatin/paclitaxel for the first line treatment of patients with advanced non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective response rate (ORR) which is defined as the proportion of patients with tumor size reduction of a predefined amount and for a minimum period of time.
