California-based Five Prime Therapeutics could receive up to $1.75 billion if they succeed in developing and getting approval for both cancer drugs and for other illnesses.

New York-based Bristol-Myers will gain exclusive worldwide rights to resulting drugs by taking over all costs of testing, applying for regulatory approval and marketing. It's also adding development of drugs for rheumatoid arthritis and a rare, sometimes life-threatening joint disorder called PVNS to the deal.
Five Prime is creating drugs that use a different mechanism for this than Opdivo and Yervoy, Bristol-Myers' pricey biologic drugs approved to treat advanced melanoma.
Under the deal, Bristol-Myers Squibb will pay Five Prime $350 million. In addition to the upfront sum, Five Prime will be eligible to receive more than $1.3 billion in development and regulatory milestone payments as well as royalties.
