Study to Assess the Safety and Durability of Viral Control Beyond 24 Weeks of Analytical Treatment Interruption After the Administration of Candidate HIV-1 Vaccines DNA.HTI, MVA.HTI and ChAdOx1.HTI or Placebo in Early Treated HIV-1 Positive Individuals (ATI Extension of AELIX-002 Study)

Summary

The AELIX-002 trial has been conducted on a cohort of individuals who started cART within the first 6 months after the primary VIH infection, thus increasing the likelihood of observing a certain rate of post-treatment controls (PTC), regardless of treatment efficacy. Although the kinetics of HIV rebound should allow observing differences between placebo and control regarding the post treatment controls rate in case of efficacy of the IMPs, assessing the length and determinants of a post-intervention control (PIC) (i.e., associated with vaccination) beyond 24 weeks is crucial for developing a curative approach to HIV infection. In this regard, an extension of the ATI phase for those individuals with pVL less than 2,000 copies/mL after 24 weeks of ATI in the AELIX-002 offers an unique research opportunity to better understand relevant aspects of the mechanisms involved in the different phenotypes of a PIC and PTC.

Conditions

  • HIV-1 Infection

Interventions

BIOLOGICAL

Vaccine + extension of the ATI period

During the AELIX-002 trial participants received the following: DNA.HTI at weeks 0, 4, and 8 and MVA.HTI at weeks 12 and 20 (DDDMM) followed by ChAdOx1.HTI at weeks 0 and 12 and MVA.HTI at week 24 (CCM), starting at least 24 weeks after MVA.HTI week 20. After that, on ATI\_extension trial, ATI will be extended for 48 weeks.

OTHER

Placebo + extension of the ATI period

During the AELIX-002 trial participants received the following: Normal saline solution at weeks 0, 4, 8, 12, and 20 (PPPPP) followed by normal saline solution at weeks 0, 12 and 24 (PPP), starting at least 24 weeks after week 20 administration. After that, on ATI\_extension trial, ATI will be extended for 48 weeks.
