Infinity Pharmaceuticals, based in Cambridge, Mass., and AbbVie have entered into a global collaboration to develop and commercialize duvelisib (IPI-145), Infinity's oral inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma, to treat cancer.

Duvelisib has shown clinical activity across a broad range of blood cancers, including indolent non-Hodgkin lymphoma (iNHL) and chronic lymphocytic leukemia (CLL). Infinity is conducting registration-focused trials evaluating the safety and efficacy of duvelisib, including DYNAMO, a phase II study in patients with iNHL, and DUO, a phase III study in patients with CLL.

Infinity will receive an upfront payment of $275 million and is eligible to receive up to $530 million in additional payments for the achievement of development, regulatory and commercial milestones, including up to $405 million for the achievement of milestones through the first commercial sale of duvelisib.

In the U.S., the companies will jointly commercialize duvelisib and will share equally in any potential profits. Outside the U.S., AbbVie will be responsible for the conduct and funding of commercialization of duvelisib, and Infinity is eligible to receive tiered double-digit royalties on net product sales, with percentages ranging from 23.5% to 30.5%.

"We believe that duvelisib is a very promising investigational treatment based on clinical data showing activity in a broad range of blood cancers," said Michael Severino, M.D., AbbVie executive vice president and chief scientific officer. "The addition of duvelisib will complement AbbVie's emerging oncology pipeline and expand our research into combination therapies to generate improved outcomes for cancer patients.”

The companies will share responsibility for the conduct of specific trials specified within an agreed-upon global development plan, with each company leading the development of certain trials within the plan. For the initial global development plan agreed to by the companies, Infinity will fund the trials it conducts and the companies will share equally the funding of trials conducted by AbbVie. The agreement includes plans to launch multiple phase II and phase III studies of duvelisib in hematologic malignancies over the next several years.
