New antibody combo tested in advanced cancer patients
NCT ID NCT05025085
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tested a new antibody drug called AGEN1777, given alone or with another antibody (a PD-1 inhibitor), in 25 people with advanced solid tumors that had stopped responding to standard treatments. The main goals were to check safety, find the right dose, and see how the drug moves through the body. Because it is a phase 1 study, it is too early to know if the drug works well.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AGEN1777 (an antibody) and a PD-1 inhibitor (another antibody)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
- What could go wrong
- This is a very early phase 1 trial with only 25 participants, so it is primarily testing safety and dosing. The drug may not shrink tumors or may cause side effects, and it is far from being proven effective.

Key Inclusion Criteria: 1. Histologically or cytologically confirmed diagnosis of metastatic or locally advanced solid tumor for which no acceptable standard therapy available or progressed on or after standard therapies. 2. Measurable disease on baseline imaging based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). 3.
