Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1 study to assess the safety of ERX-315 in patients with advanced solid tumors that have failed approved systemic therapies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of this open-label, dose escalation and cohort expansion Phase 1 clinical trial is to determine the safety, tolerability and pharmacokinetics of ERX-315 in patients with advanced solid tumors, who have progressed on prior approved systemic therapies. Participants will receive ERX-315 as an intravenous (IV) injection twice a week, over 21-day cycles.
