Trial Summary

What is the purpose of this trial?

This study is an open-label, Phase 1, multicenter study to evaluate the safety, tolerability, PK, and PD profiles of AGEN2373 as a monotherapy and in combination with botensilimab (also known as AGEN1181), and to assess the maximum tolerated dose (MTD) in subjects with advanced solid tumors.

Eligibility Criteria

Adults with advanced solid tumors that have spread or are inoperable, and who've had no success with standard treatments. They must be healthy enough overall, not pregnant, willing to use contraception, and able to provide a recent tumor tissue sample. People can't join if they've recently received certain vaccines or treatments, have severe allergies to human antibodies, uncontrolled health issues like heart disease or infections, mental incapacity, or are pregnant.

Inclusion Criteria

Specific Melanoma Criteria: Inclusion: Histological confirmation of cutaneous melanoma; Progression on or within 24 weeks of stopping treatment with a PD-1/PD-L1 confirmed per Society for Immunotherapy of Cancer (SITC); Patients with BRAF V600-positive tumor(s) should also have received prior treatment with a BRAF inhibitor (alone or in combination with a MEK inhibitor) or have declined targeted therapy. Note: Patients with BRAF V600-positive tumors with no clinically significant tumor-related symptoms nor evidence of rapidly progressive disease are not required to be treated with a BRAF inhibitor (alone or in combination with a MEK inhibitor) based on Investigator's decision.

There is evidence of a measurable disease seen on imaging scans that doctors will use a specific system to evaluate.

Trial OverviewThe trial is testing AGEN2373 alone and combined with botensilimab for safety and effectiveness in treating cancer. It's an early-phase study (Phase 1) where doctors will find the highest dose patients can take without serious side effects by gradually increasing doses for new groups of patients.
