Conditions

APOL1-mediated Proteinuric Kidney Disease (AMKD)

Brief summary

Percent change in UPCR evaluated from baseline at Week 48 (assessed at the IA) • eGFR slope (with ≥48 weeks of eGFR data assessed at the IA and at least 2 years of eGFR data assessed at the final analysis)

Detailed description

Time to composite clinical outcome of a sustained decline of ≥30% from baseline in estimated glomerular filtration rate (eGFR), the onset of ESKD (i.e., maintenance dialysis for ≥28 days, kidney transplantation, or a sustained eGFR of <15 mL/min/1.73 m2), or death. Sustained is defined as confirmation by a second measurement after ≥28 days (assessed at the final analysis)., Safety and tolerability based on adverse events (AEs), clinical laboratory values (i.e., hematology, serum chemistry, urinalysis, coagulation studies), standard 12-lead ECGs, and vital signs, Plasma PK parameters of VX-147, Acceptability of tablet formulation of VX-147 in pediatric subjects using the convenience domain of the Treatment Satisfaction Questionnaire for Medication (TSQM)
