Condition(s) targeted: Osteoporosis; HIV Infections

Intervention: Alendronate (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: French National Agency for Research on AIDS and Viral Hepatitis

Osteopenia and osteoporosis are being described more frequently in people with HIV infection. This study will test the efficacy of alendronate in comparison with a placebo after 2 years, in people with primary osteoporosis. People will receive the recommended adequate intake of calcium and vitamin D.

Clinical Details

Official title: Efficacy of Alendronate Versus Placebo in the Treatment of HIV-1 Associated Osteoporosis, a Multicenter, Randomized, Controlled Trial. ANRS 120 Fosivir

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome: Percentage of variation of lumbar BMD on DEXA scan at month 24 versus month 0 for patients included with lumbar osteoporosis (femoral for those included with only femoral osteoporosis)

Secondary outcome:

Percentage of variation of femoral T-score between M0 and M24

Percentages of variation of lumbar and femoral T score between M0 and M12

Evolution of bone metabolism markers

Occurrence of fractures

Tolerance of alendronate

Measure of the prevalence of osteopenia and osteoporosis in HIV-infected men and women

Description of the evolution of osteoporosis in HIV-infected men and women receiving calcium and vitamin D to define risk factors for osteoporosis in HIV-infected persons

Detailed description: The purposes of this trial are:

- To study the efficacy of alendronate in HIV-associated osteoporosis

- To measure the prevalence of osteoporosis in HIV patients and to detect risk factors in

a large cohort of HIV patients from the screening phase


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- Non-pregnant

- Non menopausal women

- Total femur BMD below -2. 5 SD (T score) or lumbar spine BMD below -2. 5 SD (T score)

or BMD below - 1 associated with a vertebral osteoporotic fracture (diminution of

vertebral height over 20%)

- HIV infection known for at least 5 years

- CD4 cell count over 50/mm3

- Karnofsky score over or equal to 70

- Written informed consent.

Exclusion Criteria:

- Osteoporosis resulting from a cause other than HIV: vitamin D deficiency (in that

case, after receiving high-dose calcium and vitamin D for 1 month, patients will be randomized without a new screening), renal failure, heart failure (NHYA class III or IV), treatment with glucocorticoid at a dose over or equal to 0. 5mg/kg/d for 15 days or more at time of inclusion or during the previous 6 months; thyroid or other endocrine disease if untreated for more than 6 months; hypercalciuria

- Testosterone below normal if treatment is hormonal

- BMI below or equal to 18

- Severe lung failure

- Chronic alcohol intoxication

- Gastric ulcer of disease interfering with oesophageal motility in the previous 3


- History of treatment for osteoporosis

- History of malignancy in the previous 5 years (except skin cancer and Kaposi)

- Cytotoxic chemotherapy or cytokine therapy

- Liver cirrhosis

- Breast feeding
