About the METRIC StudyThe METRIC study is a pivotal, open-label, prospectively controlled, randomized study of Glembatumumab vedotin in patients with metastatic gpNMB-expressing triple-negative breast cancer. Eligible patients must have received no more than 1 prior line of chemotherapy for advanced disease and therapy must have included a taxane and anthracycline. Patients will be randomized (2:1) to receive Glembatumumab vedotin or capecitabine. Study treatment will continue until disease progression or intolerance with tumor assessments performed at six week intervals for six months and nine week intervals thereafter. The primary objective is to evaluate the anti-cancer activity of Glembatumumab vedotin as measured by the objective response rate (ORR) and duration of progression-free survival (PFS). The study is designed to enable Celldex to apply for registration with positive results for either endpoint. Secondary endpoints include duration of response, overall survival, safety and tolerability. The Company will also assess improvements in quality of life and/or cancer-related pain as exploratory endpoints.
- No prior chemotherapy for advanced disease vs. 1 prior line of chemotherapy for advanced disease
- "Resistant" to anthracycline therapy (i.e., progression-free interval of ≤ 6 months after completing treatment) vs. "Exposed" to anthracycline therapy (i.e., progression-free interval of > 6 months after completing treatment)
