Official title
A Phase 1, Randomized, Double-blind, Placebo-controlled, Dose Escalation Study Evaluating Safety and Pharmacokinetics of VX-581 in Healthy Subjects
Overview
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single dose of VX-581 and multiple ascending doses of VX-581 alone and in combination with tezacaftor (TEZ)/deutivacaftor (D-IVA) or D-IVA for up to ten days.
Detailed description
The study is being conducted to evaluate the safety, tolerability, and pharmacokinetics of single and multiple ascending doses of VX-581 in healthy participants and consists of Screening Phase, Treatment Phase and Safety Follow-up Phase. Additionally, VX-581 will also be administered in combination with tezacaftor (TEZ)/deutivacaftor (D-IVA) or D-IVA for up to ten days. Note: This clinical trial information was submitted voluntarily under the applicable law and, therefore, certain submission deadlines may not apply. (That is, clinical trial information for this applicable clinical trial was submitted under section 402(j)(4)(A) of the Public Health Service Act and 42 CFR 11.60 and is not subject to the deadlines established by sections 402(j)(2) and (3) of the Public Health Service Act or 42 CFR 11.24 and 11.44.).
