Overview
Brief Summary
This is an open-label, multicentre, dose escalation study to characterize the safety and preliminary efficacy of the human anti-CD38 antibody MOR03087 (MOR202), in adult subjects with relapsed/refractory multiple myeloma, as monotherapy and in adult subjects with relapsed/refractory multiple myeloma in combination with standard therapy.
Detailed Description
The study enrolled patients aged 18 years or older with relapsed or refractory multiple myeloma and Karnofsky performance status of 60% or higher. Patients were assigned to the different treatment regimens with MOR202 ranging between 0·01 mg/kg and 16 mg/kg in a 3 + 3 design. Dose-escalation and expansion was done either with MOR202 intravenous infusions alone (MOR202 q2w \[twice a week\] and q1w \[weekly\] groups) or in combination with dexamethasone (MOR202 with dexamethasone group), with dexamethasone plus pomalidomide (MOR202 with dexamethasone plus pomalidomide group) or plus lenalidomide (MOR202 with dexamethasone plus lenalidomide group). Primary endpoints were safety, MOR202 maximum tolerated dose (or recommended dose) and regimen, and immunogenicity.
