Episode notes
Cancer As Immune Recognition Failure
- Jen Herbach explains cancer occurs when the immune system fails to recognize mutated cells and lets them grow.
- Adventris builds vaccines that "give the immune system glasses" to recognize cancerous mutations like KRAS.
KRAS Is A High-Impact Target
- KRAS mutations drive ~30% of cancers, notably lung, colon, and pancreatic cancers.
- Adventris targets KRAS first to treat localized pancreatic cancer and eventually aim for prevention.
Build Treatment Path Before Prevention
- Aim for treatment first and prevention later to build credibility and impact incrementally.
- Use therapeutic success to drive long-term prevention ambitions for high-prevalence targets like KRAS.
