ClinConnect Summary

This clinical trial is looking at the effectiveness and safety of different treatment options for patients with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC). Essentially, the study aims to find out how well these therapies work and how they impact patients who cannot have surgery to remove their tumors. The trial is currently recruiting participants aged 65 and older, and both men and women can join if they meet certain health criteria.

To qualify for this study, participants need to have a specific type of NSCLC that has not spread to distant parts of the body and must have received prior chemotherapy alongside radiation. They should also be willing to use an electronic device to provide feedback about their health during the trial. Interested participants can expect to receive close monitoring and care as part of the study, and they will be informed about the therapies being tested. It’s important to note that certain health conditions and prior treatments may prevent someone from participating, so a thorough evaluation will be conducted before enrolling.
