Amgen inks deal to acquire Five Prime Therapeutics for $1.9B

Levy

Amgen is set to acquire Five Prime Therapeutics, a clinical-stage biotechnology company focused on developing immuno-oncology and targeted cancer therapies.

Amgen will acquire Five Prime Therapeutics for $38.00 per share in cash, representing an equity value of approximately $1.9 billion. This acquisition adds Five Prime’s innovative pipeline to Amgen’s leading oncology portfolio.

Five Prime’s lead asset, bemarituzumab, is a first-in-class, Phase 3 ready anti-FGFR2b antibody with positive data from a randomized, placebo-controlled Phase 2 study in frontline advanced gastric or gastroesophageal junction cancer. Bemarituzumab targets FGFR2b, which has been found to be overexpressed in approximately 30% of patients with non-HER2 positive gastric cancer, as well as other solid tumors.

The acquisition of Five Prime also supports Amgen’s international expansion strategy. Gastric cancer is one of the world’s most common forms of cancer and is particularly prevalent in the Asia-Pacific region, where Amgen expects to generate significant volume growth in the coming years. Amgen plans to leverage its presence in Japan and other Asia-Pacific markets to maximize bemarituzumab’s potential. In addition, as part of this transaction, Amgen will receive a royalty percentage on future net sales in Greater China ranging from the high teens to the low twenties from a pre-existing co-development and commercialization agreement between Five Prime and Zai Lab (Shanghai) Co.

Five Prime’s additional innovative pipeline programs complement Amgen’s efforts to bring meaningful therapies to oncology patients.

“The acquisition of Five Prime offers a compelling opportunity for Amgen to strengthen our oncology portfolio with a promising late-stage, first-in-class global asset to treat gastric cancer,” said Robert  Bradway, chairman and CEO of Amgen. “We look forward to welcoming the Five Prime team to Amgen and working with them to leverage our best-in-class monoclonal antibody manufacturing capabilities to supply additional clinical materials, as well as expanded production quantities, to realize the full potential of bemarituzumab for even more patients around the world as quickly as possible.”

“This is an exciting day for patients who may one day benefit from the promise of bemaritizumab and our full pipeline. I’m so proud of the Five Prime team and the science we’ve pioneered,” said Tom Civik, president and CEO of Five Prime. “We see tremendous complementarity between the two companies. Amgen has global reach, world-class resources, and they share our deep passion for science and commitment to patients. I have full confidence that Amgen is the right company to work with us to bring our innovative cancer treatments to patients and to achieve our mission to rewrite cancer.”

The transaction is expected to close by the end of the second quarter

Goldman Sachs acted as financial advisor to Amgen and Sullivan & Cromwell as its legal advisor. Lazard acted as financial advisor to Five Prime and Cooley as its legal advisor.
