Summary

This trial tests ATRC-101, a specially designed antibody, in adults with advanced cancers that haven't responded well to other treatments. ATRC-101 helps the immune system find and attack cancer cells. ATRC-101 has shown strong antitumor activity and evidence of immune memory in early studies.

Who is the study for?
Adults with certain advanced cancers (like breast, lung, colorectal, ovarian cancer or melanoma) that can't be removed by surgery or have spread and don't respond to standard treatments. They must have measurable disease and adequate organ function. Women who can bear children and men with partners of this potential must use effective birth control.
What is being tested?
ATRC-101 is being tested alone or with other cancer drugs (Pembrolizumab/PLD). This trial checks its safety, how the body handles it, and if it works against cancer when given every 2 or 3 weeks. It's an early-phase study where everyone gets the experimental treatment.
What are the potential side effects?
Possible side effects include reactions related to the immune system affecting organs, infusion-related reactions which could happen during drug administration, fatigue, blood disorders like changes in cell counts leading to increased infection risk.

Other Research
Common treatments for colorectal cancer include immunotherapy and targeted therapies. Immunotherapy, such as immune checkpoint inhibitors, works by enhancing the body's immune response against cancer cells. These inhibitors block proteins like PD-1/PD-L1, which cancer cells use to evade the immune system. Targeted therapies, such as monoclonal antibodies, specifically target cancer cell antigens or pathways critical for tumor growth and survival. For example, cetuximab targets the epidermal growth factor receptor (EGFR) on cancer cells, inhibiting their growth. These treatments are crucial for colorectal cancer patients as they offer more personalized and effective options, especially for those who do not respond to traditional chemotherapy.
