A Phase 1, Open-Label, Dose-Escalation Study to Evaluate the Safety and Tolerability of SGN-LIV1A in Patients With Metastatic Breast Cancer
This study will examine the safety and tolerability of ladiratuzumab vedotin (LV) in patients with metastatic breast cancer. LV will be given alone or in combination with trastuzumab.
