The Company

Trillium Therapeutics (Nasdaq:TRIL) is a clinical stage biotechnology company developing next generation immunotherapies targeting CD47, a checkpoint of the innate immune system. Immunotherapy is a rapidly evolving field that is redefining cancer care by harnessing a patient’s own immune system to eliminate tumor cells. First generation immunotherapies, targeting the adaptive immune system via T cell checkpoint inhibitors, have been enormously successful scientifically (2018 Nobel prize), clinically (achieving real cure rates), and commercially (soon to be the largest drug class ever). CD47 is now emerging as one of the most promising next generation immuno-oncology targets.

Trillium has two highly differentiated CD47 blockers in development that – unlike other CD47 agents – have shown unique monotherapy activity across a range of hematologic malignancies. Under new leadership, Trillium has undergone a wide-ranging transformation program, including a major strategy reset. In 2020, the company raised over $300M, secured a strategic investment from Pfizer, and has been among the top performers on Nasdaq. After initiating an ambitious Phase 1b/2 program across multiple hematologic and solid tumor indications earlier this year, Trillium is now scaling up its organization ensure strong execution of the program.
