New fibroid Drug's hidden danger? study probes blood clot risk
NCT ID NCT07173127
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether Ryeqo, a newer hormone treatment for uterine fibroids and endometriosis, increases the risk of dangerous blood clots. Researchers will take blood samples from 30 women before they start Ryeqo and again after 3 months of treatment. The goal is to measure changes in clotting markers to better understand the drug's safety.
