The purpose of the study is to evaluate safety, tolerability, and pharmacokinetics of VX-828 and VX-828 in triple combination (TC) with Tezacaftor (TEZ)/ VX-118 or TEZ/ deutivacaftor (D-IVA) in healthy participants and VX-828 in combination with D-IVA with or without TEZ in participants with cystic fibrosis (CF).
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
This trial has completed. Results may be available via ClinicalTrials.gov or peer-reviewed publications.
Vertex Pharmaceuticals (VRTX) is the sponsoring company for this trial. BiotechSign currently grades this company C (61/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
