A Phase 3, Open-label Study Evaluating the Long-term Safety and Efficacy of VX-445/TEZ/IVA Combination Therapy in Subjects With Cystic Fibrosis Who Are 6 Years of Age and Older (VX19-445-107)

VX445-107 Triple Combination Therapy in CF Patients 6 Years of Age and Older

What is the goal of the study?

This is a Phase 3 open label clinical trial sponsored by Vertex Pharmaceuticals to evaluate the safety and efficacy of VX445/TEZ/IVA triple combination therapy in patients with Cystic Fibrosis (CF) who are 6 years of age and older. Eligible participants will rollover to this open label protocol following completion of a feeder study (at SCH VX18-445-106 Part B). Participants must be homozygous for F508del (F/F genotype) or heterozygous for F508del and a minimal function (MF) mutation that is not responsive to IVA and TEZ/IVA (F/MF genotypes). Study visits will occur on day 1, week 8, and then every 8 weeks through week 36 and then every 12 weeks; procedures will include pulmonary function testing, multiple breath washout, ECGs, sweat testing, safety labs, fecal sample, ophthalmologic examination, and sample collection for exploratory markers. Telephone calls will be made every 4 weeks between CRC study visits. Adverse events and changes in treatment will be assessed throughout the study period.
