Brief Summary:
A Phase 1b Dose Escalation Study of the Safety and Pharmacodynamics of Brontictuzumab in Combination with Chemotherapy for Subjects with Previously Treated Metastatic Colorectal Cancer.

Condition or disease Intervention/treatment Phase
Metastatic Colorectal Cancer Drug: brontictuzumab Drug: trifluridine/tipiracil Phase 1

Detailed Description:

This is a phase 1b dose escalation study of the safety and pharmacodynamics of brontictuzumab in combination with chemotherapy for subjects with previously treated metastatic colorectal cancer. This study consists of a screening period, a treatment period and a post-treatment follow up period in which patients will be followed for survival for up to 24 months. Patients will be enrolled in two stages: a dose-escalation stage and an expansion phase.

Approximately 34 patients will be enrolled in this study at approximately 5 study centers in the United States.
