What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 14 participants in total. It began in 2026-05-08 with a primary completion date of 2026-11-25.

Brief Summary

This study will test if the medicine dasatinib can lower the hidden amount of HIV in the body, called the HIV "reservoir." It will also check if dasatinib is safe and easy to take for people living with HIV who have a suppressed viral load while on antiretroviral therapy (ART). Adults 18 years or older who have been on ART for at least 48 months and have had a suppressed HIV-1 viral load for at least 36 months may be able to join. People will be randomly assigned to take dasatinib 100 mg by mouth once a day or a look-alike substance with no drug, called a placebo, for 12 weeks. Neither participants nor researchers will know who gets which (double-blind). The study team will do regular health checks and blood tests to track safety, tolerability, the HIV reservoir, and changes in immune cells. The study lasts 36 weeks total: 12 weeks of treatment and 24 weeks of follow-up, with clinic visits and possible phone calls. Fourteen people will take part; eight will get dasatinib and six will get placebo. Dasatinib may lower the HIV reservoir, but this is not guaranteed. All medicines can cause side effects, called adverse events (AE). The study team will watch closely and provide medical support. Joining is your choice, and you can leave at any time. If you leave, the team will talk with you about next steps for your care.
