Bellicum Pharmaceuticals is developing cellular immunotherapies that modulate T cell function through controllable molecular switches. The company is developing these immunotherapies to treat a range of cancers, as well as rare inherited blood disorders. The company believes the ability to modulate these cells once they are in the body will provide safer and more effective immunotherapies. We spoke to Rick Fair, CEO of Bellicum, about the company’s approach, how its molecular switches work, and its current therapeutic pipeline.
