Summary

This study tested a drug called SB-UF, which combines hormones and a plant extract, to see if it can shrink uterine fibroids in pregnant women. 66 women took the drug or a placebo throughout their pregnancy. The goal was to reduce fibroid size and help them disappear, which could make pregnancy safer and healthier.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
SB-UF (pregnenolone, pyridoxal phosphate, dydrogesterone, and Impatiens balsamina extract)
What this could lead to
If it works, this could offer a way to shrink uterine fibroids during pregnancy, potentially reducing complications and improving pregnancy outcomes.
What could go wrong
This is a small, completed Phase 4 trial with only 66 participants. Results may not apply to all women, and the combination of hormones and plant extracts may have side effects or limited effectiveness.
