Group/Cohort
Pre-Transplant Cohort
HIV-1 infected participants, enrolled prior to transplant, who receive a heterozygous or homozygous CCR∆32 cord blood transplant
Post-Transplant Cohort
HIV-1 infected participants, enrolled within 2 years after transplant, who receive a homozygous CCR∆32 cord blood transplant


Outcome Measures

Primary Outcome Measures :
  1. Survival [ Time Frame: Through 5 years post-transplant ]
    Survival and event-free survival at 100 days, Week 26, Week 52, and then every six months until five years post-transplant

  2. Graft versus host disease [ Time Frame: Through 5 years post-transplant ]
    Graft versus host disease

  3. Engraftment [ Time Frame: Through 5 years post-transplant ]
    Chimerism (≥ 98% of blood cells bearing CCR5∆32) and time to hematopoietic cell and immune recovery

  4. HIV DNA level [ Time Frame: Through 5 years post-transplant ]
    HIV-1 proviral DNA levels in peripheral blood


Biospecimen Retention:   Samples With DNA
For consenting participants, blood and tissue samples

Ages Eligible for Study:   12 Months and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
HIV-1 infected children and adults who undergo cord blood stem cell transplantation for treatment of cancer, hematopoietic disease, or other underlying disease
Criteria

Inclusion Criteria:

  • Confirmed HIV-1 infection
  • 12 months of age or older
  • Willing to provide written informed consent
  • Pre-Transplant Cohort: Underlying disease appropriate for stem cell transplant, as determined by the transplant team as part of standard of care.
  • Pre-Transplant Cohort: Availability of an appropriately matched (as determined by the transplant center) CCR5Δ32 cord blood unit (homozygous or heterozygous) and intention to proceed with transplantation. NOTE: Double cord transplants are allowed. If a double cord is used, at least one cord blood unit should be CCR5∆32 (homozygous or heterozygous).
  • Pre-Transplant Cohort: Received a CCR5Δ32 homozygous cord blood or bone marrow transplant within the last two years.

Exclusion Criteria:

• Received, or planning to receive, more than one CCR5Δ32 homozygous cord blood or bone marrow transplant.
