Brief Summary:
The purpose of this study is to test the effects of Vitamin D on renal phosphate and bone loss, which are common in HIV infected adolescents and young adults being treated with tenofovir.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| HIV Infections | Dietary Supplement: Vitamin D supplement Other: Placebo | Not Applicable |
ATN 063 tests the hypothesis that in a population of adolescents and young adults with HIV infection who are being treated with tenofovir as part of an antiretroviral (ARV) combination regimen, vitamin D supplementation will decrease renal phosphate loss, increase plasma phosphate, decrease plasma PTH, and improve markers of bone turnover, including a decrease in plasma N-telopeptide and BAP.
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 207 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Masking: | Double (Participant, Investigator) |
| Primary Purpose: | Treatment |

Drug Information available for:
Vitamin D
| Arm | Intervention/treatment |
|---|---|
|
Experimental: A: tenofovir/vitamin D
Vitamin D3 (cholecalciferol), 50,000 IU as a single capsule, will be administered orally to subjects in Group A (who are already taking Tenofovir) once every four weeks during study visits.
|
Dietary Supplement: Vitamin D supplement
Vitamin D3 (cholecalciferol), 50,000 IU as a single capsule, will be administered orally to subjects in Groups A and C once every four weeks during study visits. |
|
Placebo Comparator: B: tenofovir/placebo
A placebo will be administered orally to subjects in Group B (who are already taking Tenofovir).
|
Other: Placebo
A placebo will be administered orally to subjects in Groups B and D once every four weeks during study visits. |
|
Experimental: C: no tenofovir/vitamin D
Vitamin D3 (cholecalciferol), 50,000 IU as a single capsule, will be administered orally to subjects in Group C (who are not taking Tenofovir) once every four weeks during study visits.

|
Placebo Comparator: D: no tenofovir/placebo
A placebo will be administered orally to subjects in Group D (who are not taking Tenofovir).

Primary Outcome Measures :
- To compare the change in renal tubular reabsorption of phosphate and markers of bone turnover. [ Time Frame: Baseline, Week 4, Week 12 ]
- To measure the safety of 50,000 IU dose of vitamin D3 [ Time Frame: Baseline, Week 4, and Week 8 ]
Secondary Outcome Measures :
- To measure the relationship of vitamin D plasma concentrations to renal tubular reabsorption of phosphate and markers of bone turnover [ Time Frame: Baseline, Week 4, and Week 12 ]
- To measure the relationship of tenofovir exposure to renal tubular reabsorption of phosphate and markers of bone turnover [ Time Frame: Baseline, Week 4, and Week 12 ]
- To measure the change in tenofovir exposure and creatinine clearance [ Time Frame: Baseline, Week 4, and Week 12 ]
