NCT02901626

Brief Summary

The purpose of the study is to determine whether the Arabin pessary is a useful intervention of preterm birth at less than 37 weeks in women with a singleton gestation and a short cervix.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Preterm Delivery or Fetal Death at Less Than 37 Weeks.

    Participants who either delivered or experienced a fetal death prior to 37 weeks gestation.

    Before 37 weeks 0 days gestation, a period of up to 21 weeks from enrollment.

Secondary Outcomes (33)

  • Interval From Randomization to Delivery or Fetal Death

    from randomization to delivery or fetal death (up to a length of 189 days)

  • Gestational Age at Delivery

    From randomization to delivery (up to a length of 189 days)

  • Number of Participants With Preterm Delivery or Fetal Death at Less Than 28 Weeks Gestation

    from randomization to less than 28 weeks gestation (a period of less than 91 days)

  • Number of Participants With Preterm Delivery or Fetal Death at Less Than 32 Weeks Gestation

    from randomization to less than 32 weeks gestation (a period of less than 119 days)

  • Number of Participants With Preterm Delivery or Fetal Death at Less Than 35 Weeks Gestation

    from randomization to less than 35 weeks gestation (a period of less than 140 days)

Study Arms (2)

Arabin Cervical Pessary

EXPERIMENTAL

Arabin pessary. Participants will also receive vaginal progesterone to be administered daily, if it is the local standard of care.

Device: Arabin Cervical Pessary

No Pessary

NO INTERVENTION

Participants will also receive vaginal progesterone to be administered daily, if it is the local standard of care.

Interventions

The Arabin cervical pessary is a soft, flexible silicone pessary and fits high around the cervix with no rigid metal framework or inflexible edges that put increase pressure on the vaginal wall. It is available in a variety of sizes however three sizes will be used in this study: Pessary Size upper diameter, lower diameter 1. Nulliparous 65 mm, 32 mm 2. Multiparous 70 mm, 32 mm 3. Alternative 70 mm, 35 mm

Also known as: Arabin pessary

Eligibility Criteria

Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Singleton gestation. Twin gestation reduced to singleton either spontaneously or therapeutically, is not eligible unless the reduction occurred before 13 weeks 6 days project gestational age. Higher order multifetal gestations reduced to singletons are not eligible.
  • Gestational age at randomization between 16 weeks 0 days and 23 weeks 6 days based on clinical information and evaluation of the earliest ultrasound.
  • Cervical length on transvaginal examination of less than or equal to 20 mm by a study certified sonographer. There is no lower cervical length threshold.

You may not qualify if:

  • Cervical dilation (internal os) 3 cm or greater on digital examination or evidence of prolapsed membranes beyond the external cervical os either at the time of the qualifying cervical ultrasound examination or at a cervical exam immediately before randomization.
  • Fetal anomaly or imminent fetal demise. This includes lethal anomalies, or anomalies that may lead to early delivery or increased risk of neonatal death e.g., gastroschisis, spina bifida, serious karyotypic abnormalities. An ultrasound examination from 14 weeks 0 days to 23 weeks 6 days by project Estimated Date of Confinement (EDC) must be performed prior to randomization to evaluate the fetus for anomalies.
  • Previous spontaneous preterm birth between 16 weeks 0 days and 36 weeks 6 days. This includes induction for pPROM in a prior pregnancy.
  • Planned treatment with intramuscular 17-α hydroxy-progesterone caproate.
  • Placenta previa, because of risk of bleeding and high potential for indicated preterm birth. A low lying placenta is acceptable.
  • Active vaginal bleeding greater than spotting at the time of randomization, because of potential exacerbation due to pessary placement.
  • Symptomatic, untreated vaginal or cervical infection because of potential exacerbation due to pessary placement. Patients may be treated and if subsequently asymptomatic, randomized. However, if it is more than 10 days since the cervical length measurement, a new cervical length measurement must be obtained.
  • Rupture of membranes due to likelihood of pregnancy loss and preterm delivery as well as the risk of ascending infection which could be increased with pessary placement.
  • More than six contractions per hour reported or documented prior to randomization. It is not necessary to place the patient on a tocodynamometer.
  • Known major Mullerian anomaly of the uterus (specifically bicornuate, unicornuate, or uterine septum not resected) due to increased risk of preterm delivery which is unlikely to be affected by progesterone.
  • Any fetal/maternal condition which would require invasive in-utero assessment or treatment, for example significant red cell antigen sensitization or neonatal alloimmune thrombocytopenia.
  • Planned cerclage or cerclage already in place since it would preclude placement of a pessary.
  • Planned indicated delivery prior to 37 weeks.
  • Allergy to silicone.
  • Participation in another interventional study that influences gestational age at delivery or neonatal morbidity or mortality.
  • +2 more criteria
