Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primarily objective of this study is to assess the effect of switching from Tenofovir Disoproxil Fumurate (TDF) to TAF based ART on bone mass and turnover among women on DMPA for contraception. HIV virologically suppressed women on DMPA will be switched from their TDF based regimen to Bictergravir /Emtricitabine / Tenofovir alafenamide (B/F/TAF; Biktarvy®) in a randomized fashion. HIV infected women on TDF and non-hormonal contraception will be switched to Biktarvy®).

* Intentions to get pregnant in the next two years
* History of active tuberculosis
* Pathologic bone fracture not related to trauma (ever)
* Has pre-existing condition known to affect bone metabolism (e.g. thyrotoxicosis, tuberculosis, diabetes mellitus, liver or renal disease)
