Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
