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

- 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
- Graft versus host disease [ Time Frame: Through 5 years post-transplant ]Graft versus host disease
- Engraftment [ Time Frame: Through 5 years post-transplant ]Chimerism (≥ 98% of blood cells bearing CCR5∆32) and time to hematopoietic cell and immune recovery
- HIV DNA level [ Time Frame: Through 5 years post-transplant ]HIV-1 proviral DNA levels in peripheral blood

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 |
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.
