Brief summary

This is an open-label study, where participants will be switched from their current HIV medication to the study drug, BIC/F/TAF. Open-label means both the investigator and the participant will know what drug will be given. Participants will be followed for 48 weeks in order to monitor the efficacy, safety and tolerability of BIC/F/TAF. The investigator hypothesizes that BIC/F/TAF will be an important addition to the management of HIV-positive post renal transplant patients, especially since it is a one pill daily dosing regimen, thereby decreasing the pill burden in this population.

Interventions

DRUGBIC/F/TAF 50Mg-200Mg-25Mg Tablet

A three-drug fixed dose combination tablet containing 50mg of bictegravir, 200mg of emtricitabine, and 25mg of tenofovir alafenamide.
