Breast Cancer: A21102 (Hematology Oncology Associates)

A21102 Randomized Double-Blind Placebo Controlled Study of Subcutaneous Testosterone in the Adjuvant Treatment of Postmenopausal Women with Aromatase Inhibitor Induced Arthralgias


The purpose of this study is to compare the effects, good and/or bad, of testosterone, with a placebo (an inactive agent) on joint pain caused by taking aromatase inhibitors.

Eligible patients for this study are those that have been diagnosed with breast cancer, and are receiving a treatment with an aromatase inhibitor, either anastrozole or letrozole, and are experiencing joint symptoms. It is well known that treatment with an aromatase inhibitor (AI) can cause side effects that result in symptoms such as joint pain and stiffness, which can interfere with activities of daily living. In some patients, the treatment has to be stopped because of these symptoms.
