Further development of PRT3789 in patients with biomarker selected SMARCA4-mutated cancers paused
Kris Vaddi, Ph.D., Chief Executive Officer of Prelude, said, “We’ve decided to pause further development of PRT3789, and focus solely on PRT7732 as our go-forward strategy for our SMARCA2 Program. While PRT3789 demonstrated initial proof of concept for the mechanism, a number of considerations – including the potential need for higher target coverage throughout the dosing interval, and capital needs to continue to advance both agents – contributed to this decision. The clinical profile observed to date with PRT7732 including oral once daily dosing, safety and tolerability, oral exposures, and >90% target degradation positions us well to explore the potential for this mechanism in SMARCA4 deleted cancers and determine the path forward for continued development by year end.”
