A Phase 1, Randomized, Double-Blind, Placebo-Controlled Clinical Study to Evaluate the Safety, Reactogenicity and Immunogenicity of the HCMV-HIV Vaccine Candidate VIR-1388 in Adult Participants With Overall Good Health and Without HIV
A Phase 1, Randomized, Double-Blind, Placebo-Controlled Clinical Study to Evaluate the Safety, Reactogenicity and Immunogenicity of the HCMV-HIV Vaccine Candidate VIR-1388 in Adult Participants With Overall Good Health and Without HIV
The purpose of this study is to evaluate the safety, reactogenicity, and immunogenicity of VIR 1388 in adults in good health without HIV.
This is a Phase 1, randomized, double-blind, placebo-controlled, multicenter study in adults aged 18 to 55 years in overall good health and without HIV. Participants will be enrolled concurrently into 1 of 3 dose levels of VIR-1388 or placebo. The overall study design includes 2 study parts, Part A and Part B. Part A will be a lead-in phase enrolling a limited number of HCMV seropositive persons of non-childbearing potential (PONCBP) with a frequent safety monitoring schedule. Part B will expand enrollment into a broader population of HCMV-seropositive participants, including persons of childbearing potential required to use 2 forms of contraception and maintains a similar overall safety monitoring schedule as Part A . There is an optional long-term follow-up study that would lengthen study participation for up to 3 years post-first dose.
