On Jul. 27, 2022, City of Hope announced that a 66-year-old man who was diagnosed with HIV in 1988 had been in remission from the virus for over 17 months after stopping antiretroviral therapy (ART) for the disease following a stem cell transplant from an unrelated donor for acute leukemia.

The man lived with HIV for over 31 years, the longest of any of the three previous patients with HIV who have gone into remission after receiving a stem cell transplant for a blood cancer and HIV.
