Learning How to Fight Cancer Ep. 7, Pt. 1: Combining Treatments Strategically with Dr. Jay Chaplin
In this two-part episode of Learning How to Fight Cancer, Dr. Matt Halpert sits down with immunologist and immune engineering expert Dr. Jay Chaplin to discuss one of the most overlooked concepts in cancer treatment: timing, context, and coordination within the immune system. Together, they break down why many promising therapies fail in practice, how immunotherapies are often used in the wrong sequence, and why understanding the biology behind treatment combinations matters more than ever.
Dr. Jay shares insights from more than 30 years working in immune engineering, biologics, vaccine design, autoimmunity, and advanced cancer therapeutics. The conversation explores checkpoint inhibitors, dendritic cell therapies, inflammation, supplements, immune signaling, and why many cancer approaches may conflict when used without a strategic framework.
This discussion is designed to help patients, caregivers, and practitioners better understand how immune-based therapies actually work inside the body — and why “more” treatment is not always better treatment.
Stay tuned for even more insights in Part 2.
