Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Premature Birth Drug: Vaginal Progesterone Drug: Intramuscular Progesterone (17 alpha hydroxprogesterone caproate) Phase 4

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.

Arm Intervention/treatment
Experimental: Vaginal Progesterone
200mg micronized progesterone vaginally, to be taken daily starting at 16 0/7 - 23 6/7 weeks, and continued daily until 36 6/7 weeks' gestation or delivery
Drug: Vaginal Progesterone
Other Name: micronized progesterone

Active Comparator: Intramuscular Progesterone
250mg intramuscular progesterone to be administered weekly starting at 16 0/7 - 23 6/7 weeks, and continued weekly until 36 6/7 weeks' or delivery.
Drug: Intramuscular Progesterone (17 alpha hydroxprogesterone caproate)
Other Name: Makena




Primary Outcome Measures :
  1. Preterm birth <37 weeks [ Time Frame: up to 9 months (delivery) ]
    Incidence of gestational age of delivery less than 37 weeks


Secondary Outcome Measures :
  1. Gestational age of delivery [ Time Frame: up to 9 months (delivery) ]
  2. Preterm birth <34 weeks and <28 weeks [ Time Frame: up to 9 months (delivery) ]
  3. Second trimester cervical length <25mm [ Time Frame: 2 months ]
  4. Mode of delivery [ Time Frame: up to 9 months (delivery) ]
    Delivery mode- vaginal, cesarean, operative vaginal

  5. Maternal mortality [ Time Frame: up to 9 months (delivery) ]
  6. 5 minute Apgar score [ Time Frame: up to 9 months (delivery) ]
  7. Neonatal intensive care unit admission [ Time Frame: up to 9 months (delivery) ]
  8. Composite neonatal morbidity [ Time Frame: up to 9 months (delivery) ]
    (respiratory distress syndrome, grade III or IV intraventricular hemorrhage, culture proven sepsis, neonatal enterocolitis, and perinatal mortality up to 28 days of life)

  9. Birthweight [ Time Frame: up to 9 months (delivery) ]
  10. Perinatal mortality up to 28 days of life [ Time Frame: up to 10 months (4 weeks after delivery) ]
  11. Medication side effects [ Time Frame: up to 9 months (delivery) ]
  12. Satisfaction with medication (5 point Likert scale) [ Time Frame: up to 9 months (delivery) ]
  13. Medication adherence [ Time Frame: up to 9 months (delivery) ]

    Vaginal progesterone:

    • Overall adherence: #days used/#days of treatment x 100
    • Non-adherent: ≥4 days between doses

    Intramuscular progesterone:

    • Overall adherence: #weeks used/#weeks of treatment x 100
    • Non-adherent: ≥10 days between doses

  14. Planned subgroup analysis for the outcome preterm birth <37 weeks, <34 weeks, <28 weeks [ Time Frame: up to 9 months (delivery) ]
    Planned subgroup analysis for the primary outcome as well as the secondary outcomes of preterm birth <34 weeks and <28 weeks of patients with a cervical length <25mm versus ≥25mm, history-indicated cerclage versus not, and for those started on progesterone 16-20 weeks versus 20-24 weeks.
