A Study of AT-101 with Lenalidomide and Dexamethasone in Treating Patients with Relapsed Symptomatic Multiple Myeloma


About this study

The purpose of this study is to assess the side effects and best dose of R-(-)-gossypol acetic acid when given together with lenalidomide and dexamethasone, and to see how well it works in treating patients with multiple myeloma that has come back after a period of improvement or has gotten worse after treatment.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.
