Criteria

Inclusion Criteria:

• HIV-1 infection, documented by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen, plasma HIV-1 RNA viral load.

• NOTE: The term "licensed" refers to a US Food and Drug Administration (FDA)-approved kit, which is required for all investigational new drug (IND) studies, or for sites located in countries other than the United States, a kit that has been certified or licensed by an oversight body within that country and validated internally. Non-US sites are encouraged to use US FDA-approved methods for IND studies.

• WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

• Two separate reports of HIV-1 RNA measurements <50 copies/mL, and no HIV-1 RNA measurement >500 copies/mL, during the 48 weeks prior to entry. One of the HIV-1 RNA values must be the screening visit value, and the other value obtained between 24 and 48 weeks prior to entry.

• NOTE: All values must have been reported from a US laboratory that has a Clinical Laboratory Improvement Amendments (CLIA) certification or its equivalent, or at any network-approved non-US laboratory that is Virology Quality Assurance (VQA) certified.

• No change in antiretroviral therapy (ART) in the 24 weeks prior to entry.

• NOTE A: Modifications of ART formulation (e.g., from standard formulation to fixed dose combination or single tablet regimen) will be permitted.

• NOTE B: Within-class substitutions are not permitted.

• No plan to change ART for the study duration.

• Within 30 days prior to pre-entry, a minimum WC measurement of ≥95 cm for individuals assigned male sex at birth or ≥94 cm for individuals assigned female sex at birth.

• NOTE: For transgender study participants, sites should use the parameter that matches sex assigned at birth.

• At least one of the following drawn within 30 days prior to pre-entry by any US laboratory that has a CLIA certification or its equivalent, or at any network-approved non-US laboratory that operates in accordance with Good Clinical Laboratory Practices (GCLP) and participates in appropriate external quality assurance programs:

• NOTE: Refer to the study protocol for more details.

• CD4+ T-cell count ≥200 cells/mm^3 within 30 days prior to pre-entry (may be from standard of care) at any US laboratory that has a CLIA certification or its equivalent, or at any network-approved non-US laboratory that is Immunology Quality Assurance (IQA) certified.

• The following laboratory values obtained within 30 days prior to pre-entry by any US laboratory that has a CLIA certification or its equivalent, or at any network-approved non-US laboratory that operates in accordance with GCLP and participates in appropriate external quality assurance programs:

• Absolute neutrophil count (ANC) >750 cells/mm^3

• Hemoglobin >10 g/dL for individuals assigned male at birth and >9 g/dL for individuals assigned female at birth

• Creatinine clearance (CrCl) ≥50 mL/min, as calculated by the CKD-Epi equation.

• NOTE: Please refer to A5371 protocol-specific web page (PSWP) for the website link to calculate CrCl using the CKD-Epi calculator.

• NOTE: Calculations will be done without using cystatin C. Please refer to the A5371 Manual of Operating Procedures (MOPS) for further details.

• Aspartate aminotransferase (AST) (SGOT) ≤3 x ULN on at least two measurements, with at least one within 30 days prior to pre-entry. Participants must also have no evidence of AST >3 x ULN within the 3 months prior to entry, from routine clinical monitoring, if available. If no additional monitoring is available in the 3 months prior to entry, additional testing should be obtained within the screening interval (2-4 weeks apart) to ensure stability.

• Alanine aminotransferase (ALT) (SGPT) ≤3 x ULN on at least two measurements, with at least one within 30 days prior to pre-entry. Participants must also have no evidence of ALT >3 x ULN within the 3 months prior to entry, from routine clinical monitoring, if available. If no additional monitoring is available in the 3 months prior to entry, additional testing should be obtained within the screening interval (2-4 weeks apart) to ensure stability.
