Trial Summary

What is the purpose of this trial?

This trial is testing a new drug called AGEN1571 alone and with two other drugs in patients with advanced solid tumors. The goal is to find safe doses and see how well the drugs work. The drugs aim to either directly attack cancer cells or help the immune system fight them.

Eligibility Criteria

This trial is for adults with advanced solid tumors that have spread or are inoperable, and no standard treatments work or exist. They must be relatively healthy otherwise, with a life expectancy of at least 3 months and good organ function. Women who can have children and men with partners who can conceive must use effective birth control. People cannot join if they've had certain severe reactions to similar drugs, recent other treatments, active infections including HIV/HBV/HCV, significant heart issues, or uncontrolled high blood pressure.

Inclusion Criteria

I am a man and will use birth control as required if my partner can have children.

I had cancer before, but it meets the trial's specific conditions.

Life expectancy of at least 3 months

Exclusion Criteria

Currently participating in another study involving investigational agents or received study therapy within 3 weeks of first dose of current study drug

I haven't needed systemic treatment for an autoimmune disease in the last 2 years.

Pregnant or breastfeeding
