A Randomized, Controlled, Double-Blind Study of the Early Effects of Teriparatide versus Placebo on the Proximal Femur

IRB Number: 10001
(inactive trial)

Institutional Review Board, Hospital for Special Surgery

July 27, 2010

The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

Teriparatide (Forteo) is a potent osteoporosis medication that helps prevent fractures. However, we know little about its effect on the hip. The purpose of this study is to determine what changes Teriparatide has on hip structure and how it might help reduce hip fracture risk. We will evaluate hip bone samples from patients that we will be treating with either teriparatide (Forteo) or a placebo (an inactive substance) for 6 weeks before their surgical hip replacement. The overall participation in this study will be over a period of 10 weeks. A total of 60 subjects (men and women) will participate in this study at HSS and HHH. Study participation will involve a total of 3 study visits. Most visits are expected to last 30-60 minutes, except the last visit, which is the date of surgical hip replacement.
