|Preterm Birth||Drug: Hydroxyprogesterone 250 Mg Drug: hydroxyprogesterone 500mg||Phase 2 Phase 3|
The study will determine the association between plasma concentrations of 17-OHPC (hydroxyprogesterone caproate) and the rate of preterm birth and will evaluate the impact of several potential covariates on plasma concentrations of 17-OHPC and its efficacy. 17-OHPC (hydroxyprogesterone caproate) administration has proven effective in reducing preterm births in high risk groups but the current dose of 250mg administered IM is thought to be an inadequate for a substantial portion of women receiving the therapy. The potential benefit of identifying a therapeutic concentration range and of optimizing the dosage of 17-OHPC are substantial.
Pregnant subjects with a history of a prior spontaneous preterm birth with be randomized to either the 250mg or 500mg weekly intramuscular injections. All subjects will have trough blood samples collected immediately prior to their second injection of the 17-OHPC, at 26-30 weeks (but only after a minimum of 7 injections have been administered) , 6-9 weeks later and at the time of delivery. Another tube of maternal blood will be collected during one of the scheduled blood samples for genotyping. A cord blood specimen will also be collected and with consent, a cord blood specimen will be collected for genetic studies of the infant. We will also collect a small sample of the placenta after delivery.

Active Comparator: hydroxyprogesterone caproate 250 mg
Pregnant subject will receive 250mg of hydroxyprogesterone caproate Intramuscular injection weekly from 16 0/7-36 6/7 weeks or delivery which ever occurs first.
Drug: Hydroxyprogesterone 250 Mg
Pregnant subjects randomized to this study arm will receive a weekly Intramuscular injection of 250mg hydroxyprogesterone caproate injection weekly from 16 0/7 to 36 6/7 weeks or delivery which ever is first.
Experimental: hydroxyprogesterone caproate 500 mg
Pregnant subject will receive 500mg of hydroxyprogesterone caproate Intramuscular injection weekly from 16 0/7-36 6/7 weeks or delivery which ever occurs first.
Drug: hydroxyprogesterone 500mg
Pregnant subjects randomized to this study arm will receive a weekly Intramuscular injection of 500mg hydroxyprogesterone caproate injection weekly from 16 0/7 to 36 6/7 weeks or delivery which ever is first.
- relation of preterm birth to the plasma concentration of 17-OHPC (hydroxyprogesterone caproate) [ Time Frame: Plasma 17-OHPC concentration at 26-30 weeks ]Determine the plasma concentration of 17-OHPC at 26-30 weeks gestation and relate the concentrations of 17-OHPC to the incidence of preterm birth.
