The RIO study will see whether immune-based therapy (called bNAbs) can be used to treat HIV. These long-acting treatments will be given by infusion and be used instead of oral meds.

The study will be open to people who started HIV treatment soon after they became HIV positive.

More information will be added to this page after the study is fully approved.

Enrolment was due to start early in 2020, but was delayed because of COVID-19.

The study is now planned to open when COVID is no longer a risk, probably after the vaccines have become more widely available.
