Vaginal Versus Intramuscular Progesterone for the Prevention of Recurrent Preterm Birth (VIP)
October 5, 2021 updated by: Thomas Jefferson University
The purpose of this study is to evaluate the two suggested therapies for prevention of recurrent preterm birth (PTB) in women with a prior spontaneous preterm birth, vaginal and intramuscular progesterone to determine whether vaginal progesterone is superior to intramuscular progesterone in the prevention of recurrent preterm birth.

Detailed Description
Preterm birth is one of the leading causes of neonatal morbidity and mortality.
One of the greatest predictors of preterm birth is a history of prior spontaneous preterm birth.
Presently 17 hydroxyprogesterone caproate (intramuscular) is the only FDA approved product for the prevention of recurrent preterm birth, however recent studies suggest that vaginal progesterone may be used for this purpose, and may even be superior.
The American College of Obstetrics and Gynecology does not specify the optimal route of progesterone administration for the prevention of recurrent preterm birth.
It is our intention to compare vaginal and intramuscular progesterone to see if one is superior.
