## Summary

Usman Ahmed, former CEO of Nexus Pharmaceuticals and current CEO of Quetzal Therapeutics, explains how he built a sterile injectable manufacturing company from a family-run generics startup into a billion-dollar asset sold to Eli Lilly. He details the strategic selection of the generic drug isoproterenol, the challenges of sourcing API and building a commercial sales force, and the critical decision to invest in high-speed prefilled syringe and lyophilization capacity when competitors failed. Ahmed discusses his current focus on rare diseases at Quetzal, including an oral formulation for acute promyelocytic leukemia (APL) and a treatment for the brain-eating amoeba Naegleria fowleri, emphasizing the importance of team building and decision-making under uncertainty.
