Summary

In this episode of The Genetics Podcast, host Patrick Short interviews Ananth Sridhar, COO of Cardiorenal Programs, and Sun-Gou Ji, VP of Computational Genomics, both from BridgeBio. They discuss BridgeBio’s hub-and-spoke model for drug development, which decentralizes teams around individual molecules while centralizing certain functions. The model helps de-risk investments by uncorrelating risks across programs and enables funding for rare diseases that might otherwise be neglected. They delve into the ADH1 program, targeting the calcium-sensing receptor, highlighting challenges in patient identification and the role of human genetics in understanding disease prevalence and penetrance. They also discuss the importance of risk-adjusted net present value (NPV) over peak sales in evaluating rare disease programs, and the potential of newborn sequencing and predictive medicine. The conversation provides insights into how a biotech company leverages genetics and innovative business models to accelerate drug development for rare diseases.
