Immune Response After Stem Cell Transplant in HIV-Positive Patients With Hematologic Cancer

Phase 2
Completed
Conditions
Hematopoietic and Lymphoid Cell Neoplasm
HIV Infection
Registration Number
NCT00968630
Lead Sponsor
Fred Hutchinson Cancer Center
Brief Summary

This phase II trial studies the immune response after stem cell transplant in human immunodeficiency virus (HIV)-positive patients with hematologic cancer (blood cancer). Studying samples of blood from HIV-positive patients with cancer in the laboratory may help doctors learn more about changes that occur in the immune system after stem cell transplant.

Detailed Description

PRIMARY OBJECTIVES:

I. Examine the development of donor-derived HIV-1-specific immune response following hematopoietic cell transplant (HCT) for treatment of hematologic malignancy in HIV+ patients.

II. Examine the affect of HCT on the pool of latently infected cluster of differentiation (CD)4+ T cells in HIV+ patients given HCT for treatment of hematologic malignancy.

OUTLINE:

Patients undergo leukapheresis for analysis of HIV-1 latent reservoir at baseline and at days +90, +180, +365, and +730, and then annually thereafter as feasible.

Primary Outcome Measures
NameTimeMethod
Quantification of donor-derived HIV-1-specific immune responses following HCTUp to 1 year

HIV-1 specific immune responses will be evaluated in samples collected before and after HCT. These results will be used descriptively.

Quantification of latently infected CD4+ cells in HIV+ patientsUp to 7 years

The overall measure of efficacy will be the log change in HIV-1 latent reservoir, measured as infectious units per million.
