Primary Outcome Measures
NameTimeMethod
Safety and tolerability were based on the number and assessment of adverse events (AEs) and serious adverse events (SAEs)from baseline through safety follow-up visit (up to 29 days)
Secondary Outcome Measures
NameTimeMethod
Maximum observed concentration (Cmax) of VX-440, TEZ and its metabolites (M1-TEZ and M2-TEZ), and IVA and its metabolites (M1-IVA and M6-IVA)from Day 1 through Day 18
Area under the concentration versus time curve during a dosing interval (AUCtau) of VX-440, TEZ and its metabolites (M1-TEZ and M2-TEZ), and IVA and its metabolites (M1-IVA and M6-IVA)from Day 1 through Day 18
Observed pre-dose concentration (Ctrough) of VX-440, TEZ and its metabolites (M1-TEZ and M2-TEZ), and IVA and its metabolites (M1-IVA and M6-IVA)from Day 1 through Day 18
