A Phase Ib-IIa, Open-label, Dose-Escalation Study of the Safety, Tolerability and Pharmacokinetics of Trastuzumab Emtansine, Paclitaxel and Pertuzumab Administered Intravenously to Patients With Her2-positive, Locally Advanced or Metastatic Breast Cancer

This Phase Ib-IIa, multi-institutional, open-label, dose-escalation study is designed to evaluate the safety, tolerability, pharmacokinetics and feasibility of trastuzumab emtansine (T-DM1) administered by intravenous (IV) infusion in combination with paclitaxel (and pertuzumab, if applicable) in patients with HER2-positive, locally advanced or metastatic breast cancer.

Stanford is not currently accepting new patients for this trial. You may want to check clinicaltrials.gov to see if other locations are recruiting.
