The purpose of this study is to determine if taking daily TDF and FTC/TDF as a part of the study MTN-003 has an effect on bone mineral density (BMD).
Full description
The effect of tenofovir on bone mineral density (BMD) has not yet been studied and is of potential concern. The purpose of this study is to determine the changes in BMD among individuals receiving TDF and FTC/TDF compared with a placebo.
This substudy will enroll individuals currently participating in MTN-003. The expected duration of participation for each participant is approximately 48 months. Study treatment will be provided by MTN-003. Study treatment will not be provided by this substudy.
