The clinical-stage biotechnology company\u00a0Aelix Therapeutics<\/a> -based in the Barcelona Science Park and specialized in the discovery and development of immunotherapies for HIV infection- yesterday announced positive topline results from the AELIX-003 trial at the 2023 Conference on Retroviruses and Opportunistic Infections (CROI<\/a>). Investigational AELIX HTI vaccine in combination with Gilead\u2019s receptor TLR7 agonist, vesatolimod, enabled an extended period without antiretroviral treatment (ART) in people with HIV on antiretroviral therapy.<\/strong><\/p>\n

The AELIX-003 clinical trial evaluated the safety, tolerability, immunogenicity and efficacy of AELIX\u2019s HTI T-cell therapeutic HIV vaccine in combination with Gilead\u2019s investigational Toll-Like Receptor 7 (TLR7) agonist, vesatolimod (VES), in people with HIV on antiretroviral therapy. VES is an immune modulator being evaluated as part of an investigational combination regimen that could potentially lead to viral remission.<\/p>\n

The study met its primary and secondary endpoints for safety, tolerability and immunogenicity. The trial also evaluated the efficacy of HTI vaccines in combination with VES to avoid, delay or contain viral rebound compared to a placebo group. For this evaluation, participants underwent an analytical treatment interruption (ATI) in their antiretroviral therapy (ART) for up to 24 weeks. During this time, plasma viral load was monitored weekly.<\/p>\n

The data show that a higher proportion of HTI+VES-treated participants remained off ART for the full 24 weeks. The combination of the HTI vaccine and VES as part of an HIV cure strategy in early treated people with HIV was safe and well tolerated.<\/p>\n

Preliminary immune data suggest that HTI vaccines given in combination with VES induce high levels of HTI-specific T-cell responses; VES consistently induced pharmacodynamic response over multiple doses in combination therapy with the HTI vaccine. A lower pre-intervention reservoir was associated with better viral outcomes during the ATI, but only in the placebo group. The magnitude and breadth of vaccine response correlated with better viral outcomes. Importantly, HTI vaccines were highly immunogenic in a simpler regimen than in the previous AELIX-002 study<\/a>, and the vaccine-induced responses were associated with higher time off ART, supporting the contribution of the HTI vaccines to better viral control.<\/p>\n

\u201cThese encouraging efficacy data demonstrate that the HTI vaccine in combination with VES may be able to modulate an individual\u2019s HIV-specific immune response in a way that can potentially contribute to a better HIV control in the absence of ongoing ART.\u00a0The AELIX-003 data are exciting, and confirm what we have seen in the\u00a0AELIX-002\u00a0study, where the HTI vaccine alone also extended the time off ART for the vaccinated participants,\u201d\u00a0explains Dr. Christian Brander<\/strong>, CEO of AELIX.\u00a0\u201cThe HTI vaccine is aimed at refocusing the immune response to especially vulnerable sites in HIV. The vaccine contains antigenic regions of HIV that are more commonly targeted by individuals who naturally control the virus. Maintenance of viral remission without ART represents the next frontier in HIV infection treatment and an important step towards HIV eradication.\u201d<\/p>\n
