The journey from discovery to IND is rarely linear. It demands rigorous target validation, continuous regulatory engagement, and the use of translationally relevant models to effectively de risk programs before they advance. In this installment of Big4Bio’s ongoing series with Charles River Laboratories, we look at how the company’s One Step approach guides sponsors from discovery concept to IND-ready clinical candidate. We spoke to Manu Kohli, principal scientific advisor for Charles River Labs, about how the company’s integrated development model works, the benefits of having an end-to-end drug development solution under one roof, and how this approach helps deliver submission-ready assets on time and on budget.
