Cystic Fibrosis Clinical Trial

Official title:
A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Effect of PTI-428 in Subjects With Cystic Fibrosis

Clinical Trial Summary

The study population is comprised of adult subjects with cystic fibrosis (CF) who are homozygous for the F508del mutation and are currently receiving background treatment with tezacaftor/ivacaftor for a minimum of 1 month prior to Day 1. The planned sample size is approximately 40 subjects. 20 subjects will be assigned to PTI-428 dose level 1 or placebo and 20 subjects will be assigned to PTI-428 dose level 2 or placebo. At each dose level, subjects will be randomized at a 3:1 randomization ratio. Subjects will receive once daily oral doses of PTI-428 or placebo for 28 days, while the subjects continue to receive background treatment with tezacaftor/ivacaftor per product label.
