Indatuximab ravtansine (BT062) is an immunomodulator and antineoplastic antibody-drug conjugate.
It is the anti-CD138 chimerized MAb (nBT062)[1] linked to the maytansinoid DM4.[1]
It is being investigated as part of a treatment for multiple myeloma.[1]
Clinical trials
Multiple Myeloma
Preliminary data has been reported in 2013 from an early stage clinical trial in combination with Lenalidomide and Dexamethasone.[1] Follow up data reported "encouraging efficacy" in Dec 2014.[2]
Other
As of December 2014 it is in clinical trials for triple negative metastatic breast cancer and metastatic urinary bladder cancer.[2]
Mechanism of action
CD138 (Syndecan-1) is highly overexpressed on various solid tumors and in hematological malignancies, and represents one of the most specific target antigens for identification of multiple myeloma (MM) cells.[1] The antibody part binds to CD138 on the target cells and then the DM4 kills the cell.
