RV 546

Status:Ongoing
Phase:I
Principal Investigator(s):Punnee Pitisuttithum, Sorachai Nitayaphan
Objective:Randomized, Double Blind Evaluation of Late Boost Strategies With IHV01 (FLSC in Aluminum Phosphate) and A244 With or Without ALFQ for HIV-uninfected Participants in the HIV Vaccine Trial RV306 / WRAIR 1920 The purpose of this study is to define the safety and immunogenicity of IHV01 and A244/AHFG with and without ALFQ at a full dose and at a fractional dose (one-fifth of a full dose) in a late boost setting for participants who had previously received a late boost of AIDSVAX®B/E with or without ALVAC in RV306. Safety will be assessed through the frequency of the overall and specific post-vaccination reactions. Blood, lymph nodes, sigmoid tissue, and mucosal specimens/secretions will be collected to assess humoral, cell-mediated, innate, and mucosal immune responses. Last updated September 18, 2022
