A Study of OMP-336B11 in Subjects With Locally Advanced or Metastatic Tumors

Phase 1
Terminated
Conditions
Locally Advanced Malignant Neoplasm
Metastatic Cancer
Interventions
Registration Number
NCT03295942
Lead Sponsor
OncoMed Pharmaceuticals, Inc.
Brief Summary

The purpose of this study is to test the safety and efficacy of OMP-336B11. OMP-336B11 is an engineered human protein that was designed to bind to the GITR receptor on T cells and activate the immune system to recognize and eliminate cancer cells.

Detailed Description

This is an open-label, Phase 1a dose escalation study of OMP-336B11 administered as a single agent to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics in patients with locally advanced or metastatic tumors. 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 approximately 2 years. Patients will be enrolled in two stages: a dose-escalation stage and an expansion phase.
