ClinConnect Summary

This clinical trial is studying a new medication called SHR7280 to see how well it works in treating heavy menstrual bleeding caused by uterine fibroids. The trial is being conducted in two phases. In the first phase, researchers want to find the best dose of SHR7280, and in the second phase, they will compare this dose to a placebo (a pill with no active ingredients) to see if it effectively reduces menstrual bleeding in women with this condition.

To participate in the trial, women aged 18 to 49 who experience heavy menstrual bleeding and have been diagnosed with one or more uterine fibroids may be eligible. Participants will need to sign consent forms and meet certain health criteria, such as not having other conditions causing heavy bleeding or recent surgeries. If eligible, participants can expect to take the medication or placebo for a specific time and attend follow-up visits to monitor their progress. This trial is currently recruiting participants, so if you or someone you know might be interested, it could be a good opportunity to help advance treatment options for this condition.
