Overview

This study is being done to see if people who control HIV without antiretroviral therapy (ART) after receiving an intervention can remain off ART safely. The information collected in this study is also being used to try to understand how people control HIV without ART after receiving an intervention.

Eligibility

Step 1 Inclusion Criteria:

• Currently or previously enrolled in a qualifying ACTG or non- ACTG parent study of curative or suppressive HIV therapy that included an ATI.
• If feasible, participants should not remain co-enrolled in their respective parent study after entering A5385.
• Achieved at least 24 weeks of HIV virus suppression (as defined by the parent study) following ATI initiation, remains off ART with <4 consecutive weeks of HIV-1 RNA >1000 copies/mL, CD4+ T-cell count > 350 cells/mm3 and not experiencing symptoms of acute retroviral syndrome.

        NOTE: Participants whose participation has ended on the parent study may still qualify if
        they have not resumed ART, meet A5385's eligibility criteria, and have not met A5385 ART
        restart criteria.
          -  CD4+ T cell count >350 cells/mm3 obtained within 28 days prior to study entry at any
             US laboratory that has a Clinical Laboratory Improvement Amendments (CLIA)
             certification or its equivalent, or at any network-approved non-US laboratory that is
             IQA certified.
          -  Willingness to continue ATI for up to 96 weeks or until ART restart criteria are met,
             and to remain in follow up for 48 weeks after ART restart.
          -  For participants who are able to become pregnant, negative serum or urine pregnancy
             test within 24 hours prior to study entry by any US clinic or laboratory that has a
             CLIA certification or its equivalent, or is using a point of care (POC)/CLIA-waived
             test, or at any network-approved non-US laboratory or clinic that operates in
             accordance with Good Clinical Laboratory Practices (GCLP) and participates in
             appropriate external quality assurance programs.
        NOTE A: Participants who are able to become pregnant are individuals who have not been
        post-menopausal for at least 24 consecutive months, who have had menses within the
        preceding 24 months, and who have not undergone surgical sterilization, specifically
        hysterectomy and/or bilateral oophorectomy, tubal ligation, or bilateral salpingectomy.
        NOTE B: Acceptable documentation of hysterectomy and bilateral oophorectomy, tubal
        ligation, and tubal micro-inserts: written documentation or oral communication from a
        clinician or clinician's staff documented in source documents (physician report/letter,
        operative report or other source documentation in the patient record, discharge summary,
        laboratory report, etc.). Participant-reported history is acceptable for documentation of
        menopause.
          -  Participants who are able to become pregnant and are engaging in sexual activity that
             could lead to pregnancy must agree to use one highly effective method of contraception
             throughout the course of the study from the list below.
        Acceptable methods of contraception include:
          -  Barrier method
          -  Contraceptive subdermal implant
          -  Intrauterine device or intrauterine system
          -  Combined estrogen and progestogen oral contraceptive
          -  Injectable progestogen
          -  Contraceptive vaginal ring
          -  Percutaneous contraceptive patches
          -  Male partner sterilization with documentation of azoospermia prior to the female
             participant's entry into the study, and this male is the sole partner for that
             participant.
               -  Willingness to use barrier protection (male or female) during sexual activity
                  with all partners not on effective pre-exposure prophylaxis (PrEP) throughout
                  Step 1 ATI and until viral re-suppression in Step 2.
        NOTE: Effective PrEP includes ART treatment for partners living with HIV infection.
          -  Ability and willingness of participant to provide informed consent.
        Step 2 Inclusion Criteria:
          -  Met A5385 ART restart criteria in Step 1.
          -  Willingness to use barrier protection (male or female) during sexual activity with all
             partners not on effective PrEP until viral re-suppression.
        NOTE: Effective PrEP includes ART treatment for partners living with HIV infection.
        Step 1 Exclusion Criteria:
          -  Intercurrent illness, new medical diagnosis, laboratory abnormality, sign, or symptom
             that, in the opinion of the site investigator, would place participant at higher risk
             of morbidity during continued ATI.
          -  Medical or psychiatric condition (including pregnancy or breastfeeding) that, in the
             opinion of the site investigator, would place the participant at higher risk of
             morbidity or would interfere with adherence to study requirements.
        NOTE: Site investigators should exercise caution in invoking these criteria and instead aim
        to support potential participants who are interested and otherwise eligible to participate
        in the study.
        Step 2 Exclusion Criteria:
          -  Medical or psychiatric condition that, in the opinion of the site investigator, would
             place the participant at higher risk of morbidity or would interfere with adherence to
             study requirements.
        NOTE: Site investigators should exercise caution in invoking these criteria and instead aim
        to support potential participants who are interested and otherwise eligible to participate
