Purpose of review: Injectable cabotegravir for HIV preexposure prophylaxis (PrEP) is effective, yet global implementation has been slow. We review factors which have contributed to the delayed roll-out of this medication.
Recent findings: Fifty-three countries have approved cabotegravir for HIV prevention yet roll-out has been slow. Cabotegravir made up 2.5% of all U.S. PrEP prescriptions in 2023 and is very slowly increasing after FDA approval in 2021. Medication has not been available outside of implementation science studies in Africa and Asia. There is a lengthy process for generic medication production despite agreements signed in 2021; the first available generic dose is not anticipated until 2027. In the United States, where some of the cabotegravir medication costs can be covered under individual insurance plans, high costs and medication acquisition pathways for health centers have been complex, contributing to national implementation delays. The intensity of the staffing required for medication acquisition, insurance paperwork filing, process documentation, billing, injection administration, appointment scheduling, missed appointment monitoring and client follow up has burdened healthcare organizations.
Summary: Injectable cabotegravir PrEP has not reaped its potential to be an alternative in those for whom adherence to a daily PrEP pill is challenging. Lessons learned regarding cabotegravir medication acquisition pathways and clinical delivery strategies can inform the rollout of future HIV prevention long-acting agents.
