Summary

This study tests a new drug called BLU-5937 for adults with a chronic cough that hasn't improved with other treatments. The goal is to see if the drug can safely reduce how often and how severely people cough. About 975 participants will take either the drug or a placebo for 24 weeks, with an option to continue in an open-label extension.
