Details and patient eligibility

About

Male osteoporosis is a common and important clinical problem, associated with significant morbidity, mortality and societal expense. Approximately 10% of men =65 years of age are osteoporotic. The proposed study will evaluate efficacy and safety of oral ibandronate given 150 mg once-monthly for 12 months versus placebo in men with primary osteoporosis. Less frequent, once monthly, dosing is expected to improve patient's treatment adherence compared to a weekly dosing regimen.

Inclusion criteria

Ambulatory men at least 30 years old at screening, who are diagnosed with primary, idiopathic or hypogonadal osteoporosis according to the following criteria: Femoral neck (FN) BMD T-score < -2.0 and LS BMD T-score < -1.0 OR LS BMD T-score < -2.0 and FN BMD T-score < -1.0 and BMD T-score > 4.0 at any site
Subjects who, in the opinion of the investigator, are willing and able to comply with the protocol requirements
Subjects who have signed an informed consent

Exclusion criteria

Significant medical conditions or laboratory abnormalities, which in the opinion of the investigator may preclude the patient's ability to complete the study
Malignant disease diagnosed within the previous 5 years (except resected basal cell cancer)
Disease/disorder known to influence bone metabolism or cause of secondary osteoporosis e.g., chronic gastrointestinal or liver disease, renal disease, chronic alcoholism, malabsorption syndrome
Hypersensitivity to any component of ibandronate
Inability to stand or sit in an upright position for at least 60 minutes
Inability to swallow a tablet without breaking it
Vitamin D deficiency (serum 25-OH vitamin D <20ng/mL (equivalent to 50nmol/L) at screening
Any prevalent osteoporotic vertebral fracture identified by total spine x-ray (Total spine x-ray consists of lateral and PA films of the thoracic & lumbar spine)
Subjects who are receiving testosterone supplementation for < 2 years (if applicable) (Patients who are identified with clinical signs of hypogonadism at screening and are started on testosterone supplementation will be excluded from participation.)
Contraindications to calcium or vitamin D therapy
Administration of any investigational drug within 30 days preceding the first dose of the study drug
Previous treatment with an oral bisphosphonate within the last six months, OR more than one month of cumulative treatment within the last year, OR more than three months of cumulative treatment within the last two years AND/OR treatment with intravenous bisphosphonate within one year.
Treatment with PTH or similar anabolic agent for osteoporosis within the last two years
Treatment with other drugs affecting bone metabolism within the last six months prior to Screening including:
- Chronic systemic glucocorticoid treatment except for topical treatment at a frequency of up to twice per week
- Calcineurin inhibitors [e.g., cyclosporine, tacrolimus] or methotrexate
- Testosterone therapy (unless stabilized on medications > 2 years)
- Calcitonin
- Fluoride (dose greater than 10mg/day) or strontium for osteoporosis within the last 12 months, or past treatment for more than a total of 2 years
- Selective estrogen receptor modulators (SERMS) such as raloxifene, toremifene, tamoxifen, arzoxifene and lasofoxifene
- Anabolic steroids and other androgens, such as dehydroepiandrosterone (DHEA) or its sulphated form (DHEAs)
- Active vitamin D analogs/metabolites such as1,25-dihydroxy vitamin D (calcitriol) or 1-alpha-hydroxy vitamin D3 (1 - alpha hydroxycholecalciferol)
- Gonadotropin releasing antagonists (lupron)
ALT > twice upper limit of normal range of central laboratory
Hypercalcemia or uncorrected hypocalcemia: Serum total Ca 2+ > 10.5mg/dl or < 8.0 mg/dL (equivalent to 2.6 and 2.0 mmol/L)
GFR < 30 ml/min as determined by estimated creatinine clearance (CLcr) calculated by the Cockcroft-Gault equation:

CLcr = (140-age) * ABW X 0.85 72*Scr where : CLcr - estimated creatinine clearance Age - in years ABW - actual body weight at screening (kg) Scr - serum creatinine at screening (mg/dL)

History of major upper GI disease defined by:
- Significant upper GI bleeding within the last year requiring hospitalization or transfusion
- Recurrent peptic ulcer disease documented by radiographic or endoscopic means
- Dyspepsia or gastroesophageal reflux that is uncontrolled by medication
- Abnormalities of the esophagus that delay esophageal emptying, such as stricture, achalasia, or dysmotility
- Active gastric/duodenal ulcers
- Dyspepsia controlled by daily medication OR prior history of non-recurrent peptic ulcer disease are not considered exclusionary
WBC < 2500/µL
Serum albumin < 3.0g/dL
History of hyperthyroidism, hyperparathyroidism or osteomalacia within one year of study entry
Fewer than three (3) vertebrae in the range L1-L4 evaluable by DXA. Conditions which interfere with the BMD measurement include prevalent fracture, sequelae of orthopedic procedures (e.g., spinal fusion, metal implants, etc.), severe scoliosis and severe degenerative changes (e.g., osteophytes, sclerosis)
Bilateral hip replacement
Any restrictions, defined by site requirements for hrMRI procedure (for subset of hrMRI subjects)
