About

The purpose of this study is to test safety and anti-tumor activity of BT062 in combination with lenalidomide and dexamethasone to define the best doses for treating patients with relapsed and refractory multiple myeloma.

Full description

BT062 is an antibody-drug conjugate designed to bind and destroy Myeloma cells. The study drug is being given in multiple doses with standard Multiple Myeloma treatments, lenalidomide and dexamethasone, to test how well the treatments are tolerated and work together. This study is a dose escalation study with the purpose to find out the highest dose of BT062 that a subject can tolerate in combination with lenalidomide and dexamethasone.
