ClinConnect Summary

This clinical trial is studying a medication called diclofenac to see if it can help patients with advanced non-small cell lung cancer (NSCLC) who are already receiving immunotherapy, a treatment that helps the body's immune system fight cancer. The goal is to find out if diclofenac can reduce inflammation and potentially improve the effectiveness of the immunotherapy, making it more effective at fighting the cancer.

To participate, you must be at least 18 years old and have been diagnosed with stage III or IV NSCLC that has spread to other parts of the body. You also need to be currently receiving a specific type of immunotherapy for at least 12 weeks. If you join the trial, you can expect to take diclofenac along with your existing treatment and attend scheduled visits for check-ups. It's important to note that this trial is not yet recruiting participants, so you would need to wait until it starts. If you're interested, make sure to discuss with your doctor to see if this trial might be a good option for you.
