Paul Edmonds, a Californian man, was faced with the unimaginable – battling both cancer and HIV. However, thanks to a groundbreaking treatment five years ago, he is now free from both illnesses. Edmonds underwent a stem cell transplant, also known as an allogeneic hematopoietic cell transplantation, as a final treatment for his acute myelogenous leukemia (AML) – a type of blood cancer that had plagued him. This procedure involves transplanting healthy blood-forming stem cells from a donor into the patient, allowing the body to produce cancer-free blood. In Edmonds’ case, the donated stem cells carried a specific genetic mutation that made him resistant to HIV-1, the virus he had been living with for over three decades. This unique aspect of the treatment marked a turning point in his medical journey.

Living with HIV-1 since 1988, Edmonds had experienced the dark cloud that hung over the city of San Francisco during the AIDS crisis in the 80s. His diagnosis of HIV and full-blown AIDS felt like a death sentence at the time, despite him being on antiretroviral therapy since 1997, which effectively suppressed the virus in his blood. However, the virus’s DNA remained present in his immune cells, posing a constant threat. The stem cell transplant that Edmonds underwent not only eradicated his AML but also introduced a genetic mutation called CCR5 delta-3, making him immune to HIV-1. This rare mutation, found in only 1-2 percent of the population, was a game-changer in his treatment plan.

Following the stem cell transplant, Edmonds’ blood cells showed no signs of the HIV DNA that had once plagued his system. He became one of only five individuals worldwide to enter HIV remission through this treatment. With both his AML and HIV under control, Edmonds experienced a new lease on life. The doctors closely monitored his progress, eventually leading to the decision to discontinue his HIV treatment. Surprisingly, even after 25 months without antiretroviral therapy, Edmonds remained free of HIV-1 infection for 35 months. This remarkable outcome showcased the potential for older patients with life-threatening cancers to be cured of HIV-1 through reduced-intensity conditioning HCT.

While stem cell transplants present significant risks, the possibility of curing HIV in addition to treating cancer offers hope for many individuals. Dr. Jana Dickter, a medical professional at City of Hope involved in Edmonds’ case, expressed optimism about the dual benefits of this treatment. She emphasized the potential for others to benefit from this revolutionary approach, highlighting the immense impact it could have on patients facing similar challenges. The idea of achieving remission from both cancer and HIV simultaneously is nothing short of extraordinary, providing a glimmer of hope for those in need of life-saving interventions.
