Maraviroc on HIV-1 Infected Subjects Who Require Allogeneic Hematopoietic Cell Transplant

Phase 1
Withdrawn
Conditions
HIV-1-infection
Registration Number
NCT03118661
Lead Sponsor
Washington University School of Medicine
Brief Summary

The goal of this proposal is to determine the effect of maraviroc when it has been a part of the antiretroviral (ART) regimen given immediately after allogeneic hematopoietic cell transplant (allo-HCT) for HIV-1 infected participants who have a hematopoietic malignancy or other underlying disorder requiring an allogeneic transplant. Maraviroc has been given in practice to alleviate symptoms of graft vs. host disease (GvHD). Given its mechanism of action, it may also have an effect on the reservoir size of HIV-1 in infected patients. This study will inform potential future studies, evaluating the effect of this approach on the incidence and severity of GvHD, and determining its effect on HIV-1 reservoir.

Primary Outcome Measures
NameTimeMethod
Time to hematopoietic cell and immune recoveryUp to 100 days after transplant

-In general, the mean time of engraftment of the donor cells is approximately 90 to 100 days post-transplant and this can be monitored by measuring the percent chimerism of donor cells.

Number of participants who experience chimerismAt the time of screening

-Chimerism is measured by ≥ 98% of blood cells donor derived

Survival of participants5 years after transplant

-Number of participants who are alive 5 years after transplant

Event free survival5 years after transplant

-Defined as survival where the cancer does not recur, the graft takes, and there are no life-threatening events

HIV-1 proviral DNA levels in peripheral bloodUp to week 16 after transplant

* Obtained from peripheral blood

* Used to determine if participant can proceed to Step 2

Presence and severity of GvHDThrough 5 years after transplant

-GvHD will be measured using the NIH Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-Versus-Host Disease: IV. Response Criteria Working Group Report

HIV-1 reactivation in stimulated assayUp to week 16 after transplant

* Obtained from peripheral blood

* Used to determine if participant can proceed to Step 2

Secondary Outcome Measures
NameTimeMethod
Number of participants who achieve a state of functional cureThrough 5 years after transplant

-Functional Cure: Following the discontinuation of all HIV-1 related treatment interventions, including HAART, a participant will be considered to have achieved an HIV-1 functional cure if for at least 5 years they: maintain an undetectable plasma viral load, using standard clinical assays, have achieved full CD4+ lymphocyte recovery with normal levels of T cell activation and proliferation, and normal levels of immunoglobulins with no disease progression. It is anticipated that participants who have achieved a functional cure will continue to have detectable HIV-1 DNA in peripheral blood cells and/or tissues.

Number of participants who achieve a state of sterilizing cureThrough 5 years after transplant

-Sterilizing cure: same definition of functional cure but no detectable replication-competent virus in peripheral blood and minimal (near limits of detection) HIV-1 DNA in peripheral blood and or tissue

Number of participants who have plasma viral load <50 copies/mlThrough 5 years after transplant

-Obtained from peripheral blood

Number of participants who have gut immune reconstitutionThrough 5 years after transplant

-Will consist of tissue immunohistochemistry to analyze CD4 T cells when feasible, and for plasma markers of gut microbial translocation namely lipopolysaccharide (LPS) and soluble CD14 (sCD14) a marker of monocyte activation attributed to LPS effects

Number of participants who have existence of replication competent HIV-1 reservoirs in peripheral blood, gut and other tissue compartmentsThrough 5 years after transplant

-Obtained from peripheral blood
