Brief Summary: This is a study of HB-502 and HB-501 alternating 2-vector therapy in people living with human immunodeficiency virus HIV who are taking antiretroviral treatment ART

The benefits of available ART are short-lived and eventually there is a return of rapid HIV replication and higher viral copy number after a period of initial improvement of infection The study treatment made of HB-502 and HB-501 is designed to train the body to recognize and fight parts from substances found in HIV

This trial studies the safety tolerability and ability of HB-502 and HB-501 to stimulate an immune response against HIV in people living with HIV

Participants will receive the study treatment by injection into the muscle every 8 weeks for a duration of 24 weeks which is followed by another 24 weeks to continue looking closely at the safety profile and anti-HIV immune reaction after the last dose of study treatment
Detailed Description: This is a first-in-human Phase 1b randomized double-blind placebo-controlled multicenter study of HB-502 and HB-501 alternating 2-vector therapy in participants with HIV who are in overall good health and on suppressive ART The study will evaluate the safety reactogenicity and immunogenicity of HB-502 and HB-501 alternating 2-vector therapy

HB-502 and HB-501 are genetically engineered replicating vectors based on the arenaviruses Pichinde virus and lymphocytic choriomeningitis virus respectively The HB-502 and HB-501 vectors have been engineered to deliver HIV antigens derived from parts of key immunogenic regions of HIV type 1 HIV-1 proteins that are highly conserved within HIV-1 clade B variants The designed immunogens differ from each other by their amino acid sequence allowing for coverage of 80 of circulating HIV-1 viral variants

Two different dose levels Dose Level 1 and Dose Level 2 of HB-502 and HB-501 alternating 2-vector therapy or placebo will be administered intramuscularly every 8 weeks for 24 weeks ie 4 doses at Weeks 0 8 16 and 24 which is followed by a 24-week follow-up period

In total approximately 30 participants aged 18 to 65 years will be enrolled in this study to receive HB-502 and HB-501 alternating 2-vector therapy or placebo

About 5 Investigators and study sites in the United States are expected to participate in this study
