Brief summary
The primary objective of this study is to determine if an HIV-infected deceased kidney donor (HIVD+) transplant is safe with regards to major transplant-related and HIV-related complications.
Detailed description
This study will evaluate if receiving a kidney transplant from an HIV-infected deceased kidney donor is safe with regards to survival and major transplant-related and HIV-related complications compared to receiving a kidney from an HIV-uninfected deceased kidney donor (HIVD-). Those participants who have accepted an HIVD- organ will be randomized to be followed in the full study or followed in the nested observational group.

Eligibility
Inclusion criteria
* Participant meets the standard criteria for kidney transplant at the local center. * Participant is able to understand and provide informed consent. * Participant meets with an independent advocate per the HIV Organ Policy Equity (HOPE) Act Safeguards. * Documented HIV infection (by any licensed assay, or documented history of detectable HIV-1 RNA). * Participant is ≥18 years old. * Opportunistic complications: if prior history of an opportunistic infection, the participant has received appropriate therapy and has no evidence of active disease. * Cluster of Differentiation 4 (CD4)+ T-cell: ≥200/µL within 16 weeks of transplant. * HIV-1 is below 50 copies RNA/mL.

Exclusion criteria
* Participant has a history of progressive multifocal leukoencephalopathy (PML) or primary central nervous system (CNS) lymphoma. * Participant is pregnant or breastfeeding. * Past or current medical problems or findings from medical history, physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks or may impact the quality or interpretation of the data obtained from the study.

Pre-assignment details
510 participants agreed to participate. Per protocol, particiants were not considered enrolled (n=207) until transplant. For the observational arm, only time to graft failure and acute rejection were collected, obtained from Scientific Registry of Transplant Recipients (September 2023 data export). Other outcome data were not collected on observational arm.
