Dr. Henry Erdlei is a physician-scientist pushing the boundaries of cancer immunotherapy. An alumnus of Charité Medical School and a researcher at the Max Delbrück Center for Molecular Medicine in Berlin, Henry has dedicated years to engineering immune cells to hunt and destroy tumors — and he is now applying that expertise to GoCART Therapeutics, a biotech startup developing a modular CAR-T cell platform that could revolutionize cancer treatment. His work sits at the crossroads of biology, engineering, and AI-driven drug design.
This conversation highlights CAR-T therapy, a highly effective cancer treatment not yet available for 70% of cancer types. Targeting antigens on vital tissues like the brain and bone marrow is risky, but GoCART's 'AND gate' system requires two antigens for activation, enabling it to target 'undruggable' cancers. Henry discusses the science, business plan, funding, and his views on drug regulation in straightforward language.
KEY TOPICS COVERED
1. The Undruggable Antigen Problem: Why 70% of cancer types can't be treated with current CAR-T therapy — and how the best tumor markers are also found on tissues you can't afford to destroy.
2. GoCART's AND Gate: Dual-Antigen Recognition. How GoCART's modular system needs two antigens on a cell for activation, allowing precise tumor targeting without collateral damage.
3. AI-Driven Peptide Engineering at Scale: How machine learning enabled GoCART to analyze 180,000 trimeric sequences computationally — a process that would have cost over €200M in laboratory work — and reduce it to 20 validated candidates.
4. The Platform Business Model: Why GoCART is building the "operating system" for CAR-T therapy — a single universal cell product with swappable binders — and how partners can develop and sell binders on the platform.
5. Rethinking Drug Regulation: Henry's argument that the orphan approval pathway should become the standard: provide treatments to patients after Phase II with informed consent, conduct Phase IV surveillance on the market, and significantly reduce costs.
KEY INSIGHTS
1. The real challenge in cancer immunotherapy isn't whether CAR-T cells are effective — it's that most of the best targets for treatment are also found on healthy tissue, meaning the therapy could destroy vital organs along with the tumor. GoCART's dual-recognition system eliminates this limitation.
2. Personalized medicine doesn't have to mean creating a new drug for each patient. By modularizing the system — one universal CAR-T cell, many interchangeable binders — GoCART provides patient-specific treatment on an industrial scale, with the potential to reduce costs from $800K to just a few thousand over time.
3. The current Phase III clinical trial requirement adds hundreds of millions in costs and years of delay before patients can access treatments that are already proven effective after Phase II. Moving to a market-while-monitoring model could deliver effective therapies to patients more quickly, generate more comprehensive real-world data, and lower drug prices overall.
