Summary

This study tested an experimental drug called HMI-115 in 142 women with moderate-to-severe endometriosis pain. Over 12 weeks, researchers compared the drug to a placebo to see if it safely reduces pain during periods and pelvic pain. The goal is to find a new treatment option for this chronic condition.
