A Genentech scientist explains the real reason. In this episode of BioTalk Unzipped, Gregory Austin and Dr. Chad Briscoe sit down with Dr. Bob Liu, Senior Principal Scientist at Genentech Roche, to unpack one of the most important and misunderstood questions in modern medicine. This is a rigorous, scientifically grounded conversation on cancer biology, immunotherapy, and the real constraints shaping oncology drug development today. Dr. Liu brings over a decade of experience across antibody drug conjugates (ADCs), bispecific antibodies, and CAR-T therapies, offering a rare, insider perspective on why a universal cure remains elusive and where meaningful progress is actually being made.

It is a dynamic, adaptive system evolving within the human body. The future of oncology is not just eradication, but control, personalization, and intelligent engagement of the immune system.
