Summary

This trial is testing CX-904, a new medicine that helps the immune system fight advanced cancers that can't be removed by surgery. It works by connecting immune cells to cancer cells, making it easier for the body to attack the cancer.

Who is the study for?
This trial is for adults with advanced solid tumors that can't be surgically removed and have spread. They should have tried standard treatments already, not have serious heart issues or autoimmune diseases, and agree to use effective birth control. Those with small, symptom-free brain metastases may join after special consideration.
What is being tested?
The study tests CX-904's safety and effectiveness in treating advanced solid tumors. It will assess how the body processes the drug (PK), its impact on the tumor (PD), tolerability at different doses, and any potential benefits in shrinking or controlling tumor growth.
What are the potential side effects?
Since this is a first-in-human study for CX-904, specific side effects are unknown but could include typical reactions seen with cancer drugs such as nausea, fatigue, allergic reactions, blood count changes, organ inflammation or other unexpected symptoms.

Other Research
Common treatments for solid tumors include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy works by killing rapidly dividing cells, including cancer cells, but can also affect normal cells, leading to side effects. Targeted therapies, such as tyrosine kinase inhibitors, specifically target molecular pathways crucial for tumor growth and survival, thereby minimizing damage to normal cells. Immunotherapy, including immune checkpoint inhibitors, enhances the body's immune response against cancer cells. Novel agents like CX-904, which are being studied for their ability to inhibit tumor growth or progression, represent a promising approach by potentially offering more precise and effective treatment options with fewer side effects. These mechanisms are crucial for solid tumor patients as they aim to improve survival rates and quality of life by effectively controlling tumor growth while minimizing adverse effects.
