Safety and Efficacy of SGN-LIV1A Plus Pembrolizumab for Patients With Locally-Advanced or Metastatic Triple-Negative Breast Cancer

Phase 1
Completed
Conditions
Triple Negative Breast Neoplasms
Interventions
Registration Number
NCT03310957
Lead Sponsor
Seagen Inc.
Brief Summary

This trial studies ladiratuzumab vedotin (LV) with pembrolizumab in patients with triple-negative breast cancer. It will find out what side effects happen when participants get these two drugs. A side effect is anything the drugs do besides treating cancer. Pembrolizumab is a drug that can be used to treat triple-negative breast cancer. The trial will also find out if these drugs work to treat this type of cancer. Participants in this study have metastatic breast cancer. This means the cancer has spread to other parts of the body.

Detailed Description

The primary goal of this study is to evaluate the combination of LV, which targets LIV-1- expressing tumor cells, with the checkpoint inhibitor pembrolizumab for patients with unresectable locally-advanced or metastatic triple-negative breast cancer. These two drugs act through distinct and possibly complementary modes of action.

This is a single-arm, open-label, multicenter trial. Patients given LV and pembrolizumab during dose escalation will be monitored for frequency of dose-limiting toxicities to determine a recommended doses for expansion cohorts. In addition to safety measures, objective response rate, progression-free survival, overall survival, and other efficacy outcomes will be assessed.
