Amgen to acquire Five Prime Therapeutics for gastric cancer candidate bemarituzumab


Amgen acquisition of Five Prime Therapeutics : Amgen has agreed to acquire Five Prime Therapeutics, a clinical-stage biotech company, for about $1.9 billion, to add a phase 3 ready gastric cancer candidate called bemarituzumab.

Based in California, Five Prime Therapeutics is engaged in developing immuno-oncology and targeted cancer therapies.

Amgen will acquire the biotech company for $38.00 per share in cash.

Bemarituzumab is an anti-FGFR2b antibody, which has delivered positive data from a randomized, placebo-controlled phase 2 trial held in frontline advanced gastric or gastroesophageal junction (GEJ) cancer.

The antibody is said to inhibit fibroblast growth factors (FGFs) from binding and triggering FGFR2b to block various downstream pro-tumor signaling pathways, thereby potentially slowing the progression of cancer.
