Threatened Miscarriage Micronized Progesterone Chinese Herbal Medicine Live Birth

ClinConnect Summary

This clinical trial is investigating the effects of Chinese herbal medicine and oral progesterone on women experiencing a threatened miscarriage, which is when a pregnant woman has vaginal bleeding but the cervix is closed and the baby is still viable. The goal is to see if these treatments can help more women have a healthy live birth compared to a placebo (a treatment that has no active ingredients). The trial is looking for women between the ages of 20 and 37 who are early in their pregnancy (5 to 10 weeks along) and have symptoms of threatened miscarriage, such as bleeding or abdominal pain.

If you participate in this trial, you may receive one of the treatments or a placebo, and you will be monitored throughout the study to assess the safety and effectiveness of the treatments. It’s important to note that certain conditions, like multiple pregnancies or ectopic pregnancies (where the pregnancy develops outside the uterus), will exclude women from participating. This study is currently recruiting participants, and it aims to provide valuable information that could help improve care for women facing the risk of miscarriage.
