Study of Glembatumumab Vedotin (CDX-011) in Patients With Metastatic, gpNMB Over-Expressing, Triple Negative Breast Cancer

Official Title

A Randomized Multicentre Pivotal Study of CDX-011 (CR011-vcMMAE)in Patients With Metastatic, gpNMB Over-Expressing, Triple Negative Breast Cancer (The METRIC Study)

Summary:

The main purpose of this study is to see whether CDX-011 (glembatumumab vedotin, an antibody-drug conjugate) is effective in treating patients who have advanced Triple-Negative Breast Cancer (TNBC), and whose tumour cells make a protein called glycoprotein NMB (gpNMB), which CDX-011 binds to. The study will also further characterize the safety of CDX-011 treatment in this patient population.

Trial Description

Primary Outcome:

• Progression Free Survival (PFS)

Secondary Outcome:

• Objective Response Rate (ORR)
• Duration of Response
• Overall Survival
• Adverse Events (AE)
• Pharmacokinetics (PK)

CDX-011 consists of an antibody attached to a drug, monomethyl auristatin E (MMAE), that can kill cancer cells. The antibody delivers the drug to cancer cells by attaching to a protein called glycoprotein NMB (gpNMB) that is expressed on the cancer cell. The MMAE is then released inside of the cell, where it interferes with cell growth and may lead to cell death. This study will examine the efficacy and safety of CDX-011 in patients with advanced TNBC that makes the gpNMB protein. The effect of CDX-011 will be compared to treatment with capecitabine. Eligible patients who enroll in the study will be randomly assigned (by chance) to receive treatment with CDX-011 or with capecitabine. For every three patients enrolled, two will receive CDX-011 and one will receive treatment with capecitabine. All patients enrolled in the study will be closely monitored to determine if their cancer is responding to treatment and for any side effects that may occur.
