Bristol-Myers Squibb and Ambrx : Collaboration for Novel Biologics Programs in Diabetes and Heart Failure

September 22, 2011 - Bristol-Myers Squibb Company (NYSE: BMY) and Ambrx, Inc. announced a collaboration under which Bristol-Myers Squibb will receive exclusive worldwide rights to research, develop and commercialize biologics based on Ambrx’s research surrounding the Fibroblast Growth Factor 21 (FGF-21) protein, for potential use in treating type 2 diabetes, and the Relaxin hormone, for potential use in treating heart failure. Derivatives of FGF-21 and Relaxin were developed using Ambrx’s unique ReCODE™ platform technology to modify the native proteins with amino acid building blocks beyond the common 20 to engineer enhanced versions for investigation for therapeutic use.

Under the terms of the agreement, Bristol-Myers Squibb will make an upfront payment of $24 million to Ambrx. In addition, Bristol-Myers Squibb will make potential milestone payments and royalty payments on worldwide sales for both programs. Bristol-Myers Squibb and Ambrx will also enter research collaborations for both programs.

FGF-21 is a naturally occurring protein that has been characterized as a potent metabolic regulator, and has been shown to lower blood glucose, elevate good cholesterol and promote weight loss in preclinical studies. The lead compound in this program, ARX618, or PEG-FGF-21, is in the final stages of preclinical development.

Relaxin is a naturally occurring hormone known for its role in pregnancy and childbirth. Preclinical studies suggest Relaxin may aid in the treatment of heart failure by improving cardiac function. This program is in preclinical development... Bristol-Myers Squibb's Press Release - Ambrx's Press Release -
