ClinicalTrials.gov Identifier:	NCT00221299

Purpose

The purpose of the study is to learn if one year of treatment with parathyroid hormone (PTH), either alone or with risedronate, will increase the thickness of the bones in the hip and spine in subjects with osteoporosis from chronic low dose steroid use. During the second year, the study will also look at whether taking risedronate will preserve the bone thickness created by one year of rhPTH 1-34 treatment.

Primary Outcome Measures:

Bone Mineral Density (BMD): Examine the pattern and effect of BMD changes at hip and spine measured by DXA every 6 months. [ Time Frame: BMD changes from year 1 to year 2 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Bone Turnover Markers : Evaluate the levels of bone biochemical markers serum total calcium and urinary excretion of calcium. [ Time Frame: end of year 2 ] [ Designated as safety issue: No ]
Incident Vertebral and non-Vertebral Fractures: Evaluate using Instant Vertebral Assessment (IVA) obtained at baseline and annually thereafter. [ Time Frame: compare end of year 1 and end of year 2 ] [ Designated as safety issue: No ]

Detailed Description:

Dr. Nancy Lane and colleagues at the University of California, Davis and University of California, San Francisco will be conducting this 2-year study of human parathyroid hormone (rhPTH 1-34) alone, and rhPTH (1-34) with risedronate compared to risedronate alone in men and women with osteopenia on chronic low dose glucocorticoids (GC). This is an investigator-initiated study funded by Aventis Pharmaceuticals.

The study will be divided into 2 phases. All study subjects will receive supplemental calcium citrate and Vitamin D during the 2-year study. In year one subjects will be randomly assigned to receive PTH (subcutaneously daily) or placebo and risedronate tablets or placebo. In year two, PTH will be stopped and subjects will be re-randomized to receive risedronate tablets or placebo.

Potential study subjects will have dual x-ray absorptiometry measurements (DEXA) of the spine and hip at the screening visit. Those study subjects who meet the inclusion criteria will be invited back for a baseline visit. DEXA scans of the spine, hip, and forearm will be done at Baseline visit, 6-month, 12-month, 18-month, and 24-month follow-up visits. DEXA scan of the spine, hip, and forearm takes approximately 20 minutes to complete.

To assess incident vertebral and non-vertebral fractures, lateral thoracic and lumbar spine evaluation using Instant Vertebral Assessment [IVA] will be done at Baseline, 12-month, and 24-month follow-up visits.

The specific aims of the study are as follows:

To determine if changes in bone mineral density in the spine and hip caused by 1 year of treatment with rhPTH (1-34) alone then followed by risedronate or rhPTH (1-34) with risedronate are greater than PTH placebo and risedronate in patients with GIO who are taking calcium, MVIs and chronic low doses of glucocorticoids.
To determine if risedronate will preserve the high bone mass state created by 1 year of rhPTH (1-34) treatment.
To determine the association of biochemical markers of bone turnover with rhPTH (1-34) and risedronate both during and after treatment.
To compare, as possible, the fracture incidence between the rhPTH (1-34) alone followed by risedronate, and rhPTH (1-34) with risedronate compared to risedronate + placebo groups.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Generalized disease of bone other than related to a rheumatic disease and glucocorticoid-induced osteoporosis including: hyperparathyroidism, hypoparathyroidism, Paget's disease of bone
Diseases that may affect bone metabolism including: alcoholism, hyperthyroidism, renal impairment (creatinine > 2.5mg/dl) or hepatic impairment (SGOT levels > 2x upper limit of normal
Urinary excretion of calcium > 400mg/day
History of drug abuse
Previous use of alendronate within 6 months prior to the study
Previous use of risedronate, hormone replacement therapy or calcitonin within 2 months prior to the study
