Cervical Cerclage for Preventing Premature Birth
(COLORS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial is studying if stitching the cervix closed can prevent early births in pregnant women with a short cervix who haven't had a previous preterm birth. The procedure aims to provide support to the cervix and reduce the risk of early delivery.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is cervical cerclage safe for preventing preterm birth?
How does the treatment of cervical cerclage and vaginal progesterone differ from other treatments for preventing preterm birth?
The combination of cervical cerclage (a stitch placed in the cervix to prevent it from opening early) and vaginal progesterone (a hormone treatment) is unique because it combines two effective methods to potentially enhance the prevention of preterm birth, although it's unclear if this combination is more effective than using either method alone.13567
What data supports the effectiveness of the treatment Cervical Cerclage and Vaginal Progesterone for preventing premature birth?
Research shows that using both cervical cerclage (a stitch to support the cervix) and vaginal progesterone (a hormone treatment) together can significantly reduce the risk of very early preterm birth compared to using progesterone alone. This combination treatment has been found to prolong pregnancy and increase birth weight in women with cervical shortening.13589
Are You a Good Fit for This Trial?
This trial is for pregnant women over 18 with a single baby and a short cervix (less than or equal to 25mm) measured by ultrasound, who haven't had preterm births or losses in the second trimester before. Women can't join if they already have a cerclage, signs of labor, major fetal issues, dilated cervix over 1cm, infection suspicion, multiple babies, ruptured membranes or certain placenta problems.Inclusion Criteria
