Preserving the Promise: Improving the Culture of Biotech Investment critically examines why most biotech startups fail, as they emerge from universities into an ecosystem that inhibits rather than encourages innovation. This "Valley of Death" squanders our public investments in medical research and with them, the promise of longer and healthier lives. The authors explicate the Translation Gap faced by early stage biotech companies, the result of problematic technology transfer and investment practices, and provide specific prescriptions for improving translation of important discoveries into safe and effective therapies. In Preserving the Promise, Dessain and Fishman build on their collective experience as company founders, healthcare investor (Fishman) and physician/scientist (Dessain). The book offers a forward-looking, critical analysis of "conventional wisdom" that encumbers commercialization practices. It exposes the self-defeating habits of drug development in the Valley of Death, that waste money and extinguish innovative technologies through distorted financial incentives.
