Plain-language summary
This is a multicenter controlled interventional trial. This phase 1 trial is the first study to assess 426c.Mod.Core-C4b adjuvanted with 3M-052-AF + aluminum hydroxide suspension (Alum) in people living with HIV (PLWH).

Inclusion criteria
✓. Able and willing to complete the informed consent process, including an Assessment of Understanding (AoU): Volunteer demonstrates an understanding of this study and completes a questionnaire prior to first vaccination with verbal demonstration of understanding of questionnaire items that were answered incorrectly.
✓. 18 to 55 years old, inclusive, on day of enrollment.
✓. Confirmed HIV infection as documented by medical records or confirmatory HIV testing at screening.
✓. On suppressive ART for at least 48 weeks prior to screening. ART is defined as a combination therapy regimen including at least 1 integrase inhibitor and 1 nucleoside reverse transcriptase inhibitor (such as Dovato™) or 2 nucleoside reverse transcriptase inhibitors plus integrase inhibitors. Changes in ARVs for reasons other than virologic failure (eg, tolerability, simplification, different formulation, drug-drug interaction profile) are allowed within 48 weeks prior to screening and up until 6 weeks prior to screening. A fully active alternative ARV regimen is available, in the opinion of the Investigator, in the event of discontinuation of the current ARV regimen with development of resistance.
✓. Plasma HIV RNA \< 50 copies/mL (or lower limit of quantitation \[LLOQ\]) for at least 48 weeks prior to enrollment. NOTE: At least one viral load measurement within 48 weeks prior to the screening visit and another viral load from the screening prior to enrollment visit must be available for review. Two "blips" (ie, plasma HIV-1 RNA \> LLOQ and \< 400 copies/mL) are allowed if each blip is preceded and followed by values \< LLOQ and if the blip(s) occur(s) more than 24 weeks prior to enrollment.
✓. CD4+ cell count \> 450 cells/mm3 and CD4+ cell % ≥ 15% obtained within 40 days prior to enrollment.
✓. Available for clinic follow-up through the last clinic visit, willing to undergo leukapheresis, and willing to be contacted 12 months after the last study-product administration.

Trial details
NCT IDNCT06006546
SponsorNational Institute of Allergy and Infectious Diseases (NIAID)
. Agrees not to enroll in another study of an investigational agent during participation in the trial. If a potential participant is already enrolled in another clinical trial, approvals from the other trial sponsor and the HVTN 807 PSRT are required prior to enrollment into HVTN 807.
Exclusion criteria
✕. Current receipt of ART other than nucleoside reverse transcriptase inhibitor and integrase inhibitor.
✕. Receipt of long-acting ART within 3 months of enrollment.
✕. Documented history of resistance to any components of the current ARV regimen.
✕. Known resistance to 1 or more drugs in 2 or more ARV drug classes. NOTE: M184V/I is an exception and should not be considered when assessing this criterion. Prior HIV resistance testing is not required.
✕. ART initiation during acute HIV-1 infection (defined as within 1 year of HIV-1 acquisition, if known).
✕. History of an HIV-associated malignancy (including Kaposi's sarcoma), and any type of lymphoma or virus-associated cancers.
✕. History of HIV-associated neurocognitive disease or progressive multifocal leukoencephalopathy.
✕. History of HIV-related illness under US Centers for Disease Control (CDC) Category C (except for recurrent pneumonia) within 10 years prior to screening, based on available medical history and assessed by the Investigator for clinical relevance. Anyone with a history of CD4 \< 200 cells/mm3 on one or more occasions, based on available medical history and assessed by the Investigator for clinical relevance. Documentation of every case with history of CD4 \< 200 cells/mm3 must be provided to the Sponsor and PSRT, who will determine eligibility on a case-by-case basis. NOTE: History of treated and resolved pulmonary tuberculosis (TB) will not be exclusionary.
