Oslo patient’s HIV remission sparks hope after brother’s stem‑cell transplant

The Oslo patient, a 57‑year‑old Norwegian who has lived with HIV for two decades, appears to have entered long‑term remission after receiving a stem‑cell graft from his brother, who carries the CCR5‑Δ32 mutation that blocks viral entry.

Oslo patient’s breakthrough in HIV treatment

Doctors performed the allogeneic bone‑marrow transplant in 2019, a procedure traditionally reserved for aggressive blood cancers. Within months, the virus became undetectable without antiretroviral therapy, echoing the outcomes seen in the earlier “Berlin patient.”

To date, ↑4 individuals worldwide have achieved similar remission, a figure that, while modest, fuels renewed investment in gene‑editing research.

“This case reshapes our expectations for a functional cure,” said Dr. Andrea Gallo of the University of Oslo, as reported by Reuters.

Scientists caution that stem‑cell transplants carry significant risks, including graft‑versus‑host disease, and are not a scalable solution for the global epidemic. Nonetheless, the success story has spurred biotech firms to accelerate trials of CRISPR‑based CCR5 editing, a development highlighted in recent AP News coverage.
