July 22, 2019 updated by: Biotest Pharmaceuticals Corporation

A Phase I/IIa Multi-dose Escalation Study of BT062 in Combination With Lenalidomide or Pomalidomide and Dexamethasone in Subjects With Relapsed or Relapsed/Refractory Multiple Myeloma

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.

Detailed 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: BT062
BT062 administered intravenously on days 1, 8 and 15 of each 28-day cycle, and lenalidomide or pomalidomide and dexamethasone administered orally to subjects with relapsed or relapsed/refractory MM

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Determination of optimal dose of BT062 (Phase I part)
Time Frame: 6 months
The Phase I part will follow a standard dose escalation design with at least 3 patients per dose level to define optimal dose of BT062 in combination with lenalidomide/dexamethasone. Optimal dose will be defined by dose limiting toxicities (DLT) observed during Cycle 1 (28 days).
6 months
Evaluation of response (Phase IIa part)
Time Frame: 18 months
Response to treatment with optimal dose of BT062 (defined in Phase I part) in combination with lenalidomide/dexamethasone or pomalidomide/dexamethasone will be evaluated at baseline and at start of each Cycle (every 28 days). Response evaluation will be primarily based on assessment of M-protein and serum free light chains. If clinically required bone marrow analysis, plasmacytoma evaluation, and skeletal survey will be performed.
18 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Qualitative toxicities of BT062 in combination with lenalidomide/dexamethasone or pomalidomide/dexamethasone
Time Frame: 24 months
Safety will be assessed at each visit by incidence of adverse events and by clinically significant changes in the patients physical examination, vital signs, and clinically laboratory results
24 months
Pharmacokinetics of BT062 in combination with lenalidomide/dexamethasone or pomalidomide/dexamethasone
Time Frame: 24 months
Pharmacokinetic parameters will be assessed from plasma by measuring intact BT062 and free maytansinoid (DM4)
24 months
Assessment of Time To Event end points
Time Frame: 24 months
Based on the response evaluation, the following Time To Event end points will be evaluated: Time To Progression, Progression Free Survival, Time To Next Treatment, Duration Of Response, Overall survival.
24 months
Quantitative toxicities of BT062 in combination with lenalidomide/dexamethasone or pomalidomide/dexamethasone
Time Frame: 24 months
Safety will be assessed at each visit by incidence of adverse events and by clinically significant changes in the patients physical examination, vital signs, and clinically laboratory results
24 months
