CTP-656, a novel, next generation CFTR potentiator, is a once-daily modified form of ivacaftor (Kalydeco; Vertex) developed through the application of deuterium chemistry. CTP-656 has shown to demonstrate superior pharmacokinetic profile compared to Kalydeco in a Phase 1 cross-over study, including a reduced rate of clearance, longer half-life, substantially increased exposure and greater plasma levels at 24 hours.
