What You Need to Know Before You Apply

What is the purpose of this trial?

This phase I trial studies the safety, side effects, and best dose of ADG126, in combination with ivonescimab alone, in combination with ivonescimab, leucovorin, and fluorouracil, or in combination with ivonescimab and leucovorin, fluorouracil, and irinotecan (FOLFIRI regimen) in treating patients with microsatellite stable (MSS) colorectal cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or has spread from where it first started (primary site) to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as ivonescimab and ADG126, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ivonescimab may also stop or slow the cancer by blocking the growth of new blood vessels necessary for tumor growth. Leucovorin calcium is a type of drug called a folic acid analog, which means it is similar to the vitamin folic acid. It is used in combination with certain chemotherapy drugs to enhance their ability to kill tumor cells or to lessen their harmful side effects. Fluorouracil is a type of chemotherapy called an antimetabolite, which is a drug that mimics a natural chemical and prevents its use in cells. It interferes with the production of a key component of deoxyribonucleic acid (DNA), which prevents the DNA from copying itself. This causes tumor cells and other rapidly dividing cells to die. Fluorouracil also gets incorporated into ribonucleic acid (RNA) and DNA, disrupting critical cell functions. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Giving ADG126 with ivonescimab, with or without leucovorin and fluorouracil or FOLFIRI regimen, may be safe in treating patients with MSS advanced/metastatic colorectal cancer.

Are You a Good Fit for This Trial?

This trial is for adults over 18 with advanced or metastatic microsatellite stable colorectal cancer, confirmed by a certified test. Participants must have an ECOG performance status of ≤1, measurable disease, and recovered from previous cancer therapies. Specific arms require progression after certain treatments or eligibility for maintenance therapy.

Inclusion Criteria

I am eligible for maintenance chemotherapy with 5-FU/LV or 5-FU/LV plus bevacizumab.
I have recovered from serious side effects of cancer treatment, except for hair loss.
I have given my consent or my legal representative has.

Trial Overview

The trial tests ADG126 and ivonescimab alone or combined with leucovorin and fluorouracil (FOLFIRI regimen) in treating advanced/metastatic colorectal cancer. It explores the safety, side effects, and optimal dosages of these immunotherapies that may inhibit tumor growth and spread.
