Pfizer, an American multinational pharmaceutical and biotechnology corporation, completed the acquisition of Trillium Therapeutics, a clinical stage immuno-oncology company, for $2.26bn. "We’re delighted to announce Pfizer’s proposed acquisition of Trillium. Today’s announcement reflects Trillium’s potentially best in class SIRPα–CD47 status and contribution to immuno-oncology. Trillium has the only known SIRPα–CD47 targeting molecules with clinically meaningful monotherapy responses as well as a strong basis for combination therapies, which is supported by preclinical evidence with a diverse set of therapeutic agents. With Pfizer’s global reach and deep capabilities, we believe our programs will advance more quickly to the patients we’ve always aspired to serve. We believe this is a good outcome for patients and our shareholders," Jan Skvarka, Trillium CEO.
