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 in group 1 will be re-randomized to receive risedronate tablets or placebo. Subjects in group 2 and 3 will continue on risedronate tablets.
In year one of the study, subjects were randomly assigned to one of the following treatment groups.
- Group 1: rhPTH (1-34) (20ug subcutaneously daily) + riesdronate placebo tablets
- Group 2: rhPTh (1-34) (20ug subcutaneously daily) + risedronate tablets (35mg/wk)
- Group 3: rhPTh placebo (subcutaneous injections of normal saline) + risedronate tablets (35mg/wk)
In year two of the study, beginning at the 12 month timepoint
Group 1 subjects were re-randomized to either:
Group 1a: risedronate (35mg/wk) or Group 1b: risedronate placebo
- Group 2 subjects continued risedronate (35mg/wk)
- Group 3 subjects continued risedronate (35mg/wk)
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.

Description
Inclusion Criteria:
- Men and women, greater than 18 years of age with a history of glucocorticoid therapy with prednisone ≥ 7.5mg/d for 6 months, and currently on prednisone ≥ 5mg /day.
- DXA of the lumbar spine (L1-L4) or total hip or femoral neck T score ≤ -1.5 with or without a prevalent vertebral fracture. (The T score is the number of standard deviations above or below the population mean for young, normal pre-menopausal females age 30).
- Investigators are satisfied that that there is no physical condition that would prevent a patient from receiving the proposed treatment regimens.
- Patient is ambulatory and able to return to the site of the investigation at specified time during the study.
- The patient is willing to participate in the proposed study as evidenced by signing an informed consent.
- Women of childbearing age are willing to use 2 forms of contraception during the entire study period.
- Have at least one analyzable BMD site: lumbar spine and/or proximal femur
Exclusion 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
- History of unstable cardiovascular disease or uncontrolled hypertension
- Severe scoliosis, greater than 2 lumbar fractures, or spinal surgery such that a precise bone mass measurement could be affected
- History of gastrointestinal intolerance to bisphosphonates
- History of cancer within 5 years of the study
- Patients on glucocorticoids for organ transplantation
