Graduate school and choosing immunotherapy

For decades, drug discovery has shifted away from nature and toward biology-first approaches. Viswa Colluru believes that shift was a catastrophic mistake. His company, Enveda Biosciences, has raised over $500 million to build a “search engine for nature’s chemistry.” The mission is personal: he grew up around his father’s pharmacy in India and later lost his mother to a treatable cancer whose medicine his family couldn’t afford. Many life-changing medicines, including morphine, aspirin, and metformin, originated in nature, but there has never been a reliable, scalable way to systematically explore its chemistry. Colluru founded Enveda in 2019 with $55,000 of his own savings to change that. The company has since identified 18 drug candidates, with three now in clinical trials.

In our conversation, we explore:

• Why the pharmaceutical industry abandoned nature (and why that was a massive mistake)
• How Enveda built a system to decode unknown molecules in nature
• The deeply personal story of his mother’s battle with leukemia and how it shaped his life’s work
• Why old ideas, from immunotherapy to natural products, often hold the most latent potential
• How Enveda developed 18 drug candidates for about $1 million each instead of $10-15 million
• Enveda’s three leading drug candidates targeting eczema, obesity, and ulcerative colitis
• Why first-in-class medicines capture the vast majority of returns in pharma
• What competitive table tennis taught him about building companies
