An Electrocardiogram Study to Evaluate the Effect of Vanzacaftor on the QT/QTc Interval in Healthy Participants

Registration Number
NCT05867147
Lead Sponsor
Vertex Pharmaceuticals Incorporated
Brief Summary

The purpose of this study is to evaluate the effect of Vanzacaftor (VNZ) on QTcF, as well as the pharmacokinetic (PK), safety, and tolerability of VNZ in healthy participants.
