ClinConnect Summary

This clinical trial is studying a medication called pembrolizumab (MK-3475) for people with advanced solid tumors that have not responded to standard treatments. The trial aims to see how well this medication works for various types of advanced cancer, including anal cancer, biliary cancer, small cell lung cancer, and several others. To participate, individuals must have a confirmed diagnosis of one of these cancers and have already tried at least one standard treatment that didn’t work. They should also be able to provide a sample of their tumor tissue for analysis.

Participants in this study can expect to receive pembrolizumab, which is given through an infusion, and they will be monitored closely by the research team for any side effects and to evaluate how their cancer responds to the treatment. The trial is currently recruiting participants, and it is important to note that there are specific criteria regarding previous treatments and health conditions that need to be met in order to qualify. If you or a loved one is considering participating, it may be helpful to discuss it with a doctor to see if this trial is a suitable option.
