ClinConnect Summary

The REFINE-lung clinical trial is studying a new approach to treating advanced non-small cell lung cancer (NSCLC) using a medication called pembrolizumab. This trial aims to find out if giving pembrolizumab less frequently—every 12 weeks instead of every 6 weeks—after the first six months of treatment is safe and still effective for patients who are doing well. If early results show that the 12-week schedule works just as well, other patients may also be placed in groups receiving pembrolizumab every 9, 15, or even 18 weeks. If a patient’s cancer progresses while on a reduced schedule, they will have the option to return to the standard treatment frequency.

To participate, patients need to be at least 18 years old and have already received six months of pembrolizumab treatment, showing continued benefits without experiencing disease progression. They must also be willing to follow the study guidelines. The trial is currently recruiting participants of all genders. If you join the study, you can expect regular check-ups and monitoring to ensure your safety and the effectiveness of the treatment. It’s important to note that patients with new cancers or those who have not tolerated their treatment well cannot participate.
