Trial design

Randomised, open-label, active intervention: cab + rpv la (cabotegravir + rilpivirine long-acting intramuscular injections; initiation injections on day 1 and month 1 then maintenance injections every 2 months through month 23). comparator arm: standard-of-care oral art (participants remain on their current oral art up to month 6; participants with viral load <50 c/ml at month 6 may have the option to switch to cab + rpv la with initiation injections ~1 week after month 6 and month 7, then maintenance every 2 months). specific injection product doses in protocol: vocabria (cabotegravir) 600 mg im and rekambys (rilpivirine) 900 mg im prolonged-release injections.-controlled Phase III trial in Spain, Germany, Belgium and others.
