A Phase 4 Cross-Sectional Study of Bone Mineral Density in HIV-1 Infected Subjects - Full Text View

Purpose

A Phase 4 study is to characterize the profile of low bone mineral density (BMD) in ≥ 50 year old male subjects and post-menopausal female subjects on any tenofovir disoproxil fumarate (TDF)-based regimen

Primary Outcome Measures:

Femoral Neck and Spine (L1-4) T-score [ Time Frame: Day 1 ]
Femoral neck and spine (L1-4) T-score will be used to characterize the profile of low bone mineral density (BMD) in ≥ 50 year old male subjects and post-menopausal female subjects on any tenofovir disoproxil fumarate (TDF)-based regimen relative to those on any non-TDF-based regimen for HIV infection.

Secondary Outcome Measures:

Observed T-score < -2 (yes/no) for femoral neck and spine (L1-4) [ Time Frame: Day 1 ]
Observed T-score for femoral neck and spine will be used to further characterize low BMD.
Observed -2 ≤ T-score < -1 (yes/no) for femoral neck and spine (L1-4) [ Time Frame: Day 1 ]
Observed T-score for femoral neck and spine will be used to further characterize low BMD.

Criteria

Inclusion Criteria:

Must have the ability to understand and sign a written informed consent form, which must be obtained prior to initiation of any study procedures.
HIV-1 infected subjects regardless of race or ethnicity
Use of one of the following taken as a stable, continuous, NRTI-containing antiretroviral (ARV) regimen for ≥ 3 years are allowed (within-class change of agents other than TDF within 3 years of study entry are permitted as specified):
- TDF plus PI/r-containing regimen including subjects who switched from one TDF plus PI/r regimen to another TDF plus PI/r regimen
- a TDF plus non-PI/r-containing regimen including subjects who switched from one TDF plus non-PI/r regimen to another TDF plus non-PI/r regimen
- a Non-TDF NRTI plus a PI/r-containing regimen including subjects who switched from one non-TDF NRTI plus PI/r regimen to another non-TDF NRTI regimen plus PI/r regimen
- a Non-TDF NRTI plus a non-PI/r‑containing regimen including subjects who switched from one non-TDF NRTI plus non-PI/r regimen to another non-TDF NRTI regimen plus non‑PI/r regimen
Of note, subjects in the non-TDF groups must have never taken a regimen that includes TDF (including previous exposure to TDF for pre-exposure prophylaxis (PrEP))
Subjects included in the TDF groups must have always taken a regimen that includes TDF. Non-PI/r agents include non-nucleoside reverse transcriptase inhibitors (NNRTIs), integrase inhibitors, triple nucleoside inhibitors and non-boosted protease inhibitors
Male subjects must be ≥ 50 years of age
Female subjects must be postmenopausal. Menopause can be assumed to have occurred in a woman when there is either appropriate medical documentation of prior complete bilateral oophorectomy or permanent cessation of previously occurring menses > 12 months as a result of ovarian failure or bilateral oophorectomy with documentation of hormonal deficiency by a certified healthcare provided
Adequate records available to evaluate medical history for the 3 years prior to study entry

Exclusion Criteria:

Subject has a contraindication to dual-energy X-ray absorptiometry (DEXA) scans
Subject has a history of osteoporosis before initiating Highly Active Antiretroviral Treatment (HAART)
