All participants received VX-147 at a dosage of 15 mg once daily (qd) for 2 weeks and VX-147 at a dosage of 45 mg qd for 11 weeks. Part A was enrolled in 2 cohorts: Cohort 1 and Cohort 2. Cohort 1 included participants with urine protein to creatinine ratio (UPCR) approximately greater than or equal to (≥) 3 g/g (± 10%) and less than (<) 10 g/g and estimated glomerular filtration rate (eGFR) approximately ≥30 mL/min/1.73 m2 (± 10%). Cohort 2 included participants with UPCR approximately ≥0.8 g/g (± 10%) and <2.7 g/g and eGFR approximately ≥30 mL/min/1.73 m2.
