Bristol-Myers Squibb Co. (BMY) and Nektar Therapeutics (NKTR) have struck a deal to collaborate on developing an immuno-oncology treatment to be used in combination with other drugs.

Bristol-Myers Squibb will make an upfront payment of $1 billion to Nektar and buy $850 million of the San Francisco company's shares as part of the agreement, the companies said Wednesday.

The development plan for the candidate, called NKTR-214, calls for studying its use in combination with Bristol-Myers Squibb's Opdivo and Opdivo plus Yervoy across several tumor types.

Assuming Nektar hits development and regulatory-approval milestones, Nektar could receive as much as $1.43 billion, the companies said. Reaching certain sales goals could earn Nektar an additional $350 million.

Nektar will book revenue for world-wide sales of the drug candidate, the companies said. The companies will split global profits for the drug candidate, with Nektar receiving 65% and Bristol-Myers Squibb 35%. Bristol-Myers Squibb will retain 100% of revenue for its own medicines, the companies said.

The companies entered into a clinical collaboration in September 2016 to evaluate whether the drug candidate used in combination with Opdivo could improve outcomes for patients. A clinical study is underway in more than 350 patients with melanoma, and cancer of the kidney, lung, bladder, and breast.

Bristol-Myers Squibb has a market value of more than $104 billion.

Shares in Nektar fell 2.9% in premarket trading, while Bristol-Myers Squibb shares were little changed.
