Brief Summary:
The purpose of this study is to find out about the safety of sirolimus in individuals with HIV infection who are also being treated with ART. The investigators want to learn whether sirolimus will decrease inflammation and immune activation in the body; whether sirolimus will change the level of HIV in the participants' blood; and how sirolimus interacts with ART in the blood. Sirolimus is approved by the Food and Drug Administration (FDA) to prevent organ rejection in patients aged 13 years and older receiving kidney transplants. Sirolimus has also been used for the prevention of complications after stem cell transplants and as a treatment for certain kinds of cancers in HIV-infected patients.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
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 FDA-approved kit, which is required for all investigational new drug (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 (eg, indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

  • Currently on continuous ART for ≥24 months prior to study entry. This is defined as continuous active therapy for the 24-month period prior to study entry with no treatment interruption longer than 5 consecutive days and a total duration off treatment of no more than 7 days in the 90 days prior to study entry.
  • CD4+ cell count ≥400 cells/mm3 obtained within 60 days prior to study entry at 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.
  • Plasma HIV-1 RNA below the level of quantification (eg, <20, <40, <50, or <75 copies/mL depending on the assay) for ≥24 months 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. Participants must have at least one documented HIV-1 RNA below the level of quantification obtained 12-24 months prior to screening and one HIV-1 RNA less than the level of quantification obtained within 12 months prior to the screening HIV-1 RNA.

NOTE:

  • One month = 30 days.
  • Plasma HIV-1 RNA measurements above the limit of quantification but <200 copies/mL in the 24 months prior to screening are allowed if directly followed by HIV-1 RNA below assay limit, but none in the 6 months prior to screening.

    • Plasma HIV-1 RNA level of <40 copies/mL obtained by the Abbott real time assay or <20 copies/mL by the Roche COBAS TaqMan HIV-1 Test, Version 2.0 assay within 60 days prior to study entry at any laboratory that has a CLIA certification or its equivalent.
    • For females of reproductive potential (defined as women who have not been postmenopausal for at least 24 consecutive months or documentation that the woman has undergone hysterectomy, bilateral oophorectomy, or salpingectomy), negative serum or urine pregnancy test within 48 hours prior to study entry.

NOTE: Patient-reported history is acceptable documentation of hysterectomy and bilateral oophorectomy, tubal ligation, tubal micro-inserts, vasectomy, and menopause.

  • Females of reproductive potential who are participating in sexual activity that could lead to pregnancy must agree to initiate effective contraceptives before sirolimus therapy, continue use during sirolimus therapy, and maintain use for at least 12 weeks after sirolimus therapy has been stopped.

    • Ability and willingness of subject or legal guardian/representative to provide informed consent.
    • Laboratory evaluations obtained within 60 days prior to 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 GCP and participates in appropriate external quality assurance programs.
  • White blood cell (WBC) ≥3000/mm3
  • Platelet count ≥125,000/mm3
  • ANC >1300/mm3
  • Aspartate aminotransferase (AST) <1.25 x ULN
