Primary Outcome Measures:
  • Time of Maximum Plasma Concentration (Tmax) of Misoprostol After Insertion [ Time Frame: From study drug insertion up to 1 hour post study drug removal. ] [ Designated as safety issue: No ]
    The timepoints over which the pharmacokinetic measurements were assessed, and deemed as accurate and appropriate, were as follows: 0 hours (baseline), 0.5,1, 2, 4, 6, 8, 10 and 14 hours after insertion of the study drug, immediately prior to removal of the study drug and 0.5 and 1 hour after removal of the study drug. The 10 hour and 14 hour blood samples were obtained if the subject still had the study drug in place at those timepoints.

  • Maximum Plasma Concentration (Cmax) of Misoprostol up to 1 Hour Post Study Drug Removal [ Time Frame: From study drug insertion up to 1 hour post study drug removal ] [ Designated as safety issue: No ]
    The timepoints over which the pharmacokinetic measurements were assessed, and deemed as accurate and appropriate, were as follows: 0 hours (baseline), 0.5,1, 2, 4, 6, 8, 10 and 14 hours after insertion of the study drug, immediately prior to removal of the study drug and 0.5 and 1 hour after removal of the study drug. The 10 hour and 14 hour blood samples were obtained if the subject still had the study drug in place at those timepoints.


Secondary Outcome Measures:
  • Rate of Adverse Events. [ Time Frame: From study drug administration to hospital discharge (approximately 48-72 hours). ] [ Designated as safety issue: Yes ]
    All adverse events were rated by the Investigator as mild, moderate or severe and classified as having no relationship, possible relationship or a probable relationship to the study drug. These assessments were deemed as accurate and appropriate for the reporting of all serious and non serious adverse events.


Enrollment: 24
Study Start Date: May 2011
Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MVI 200
MVI 200 mcg vaginal insert
Drug: MVI 200
Dose reservoir of 200 mcg of misoprostol in a hydrogel polymer vaginal insert within a retrieval system. The MVI 200 will be kept in place for up to 24 hours or will be removed earlier if one of the following occur: onset of active labor, intrapartum adverse event necessitating discontinuation of the study drug, other reasons including maternal request.

Criteria

Inclusion Criteria:

  • Provide written informed consent;
  • Pregnant women at ≥ 36 weeks 0 days inclusive gestation;
  • Women aged 18 years or older;
  • Candidate for pharmacologic induction of labor;

  • Diagnosed congenital anomalies, not including polydactyly;
  • Any evidence of fetal compromise at baseline (e.g., non-reassuring fetal heart rate pattern or meconium staining);
  • Amnioinfusion or other treatment of non-reassuring fetal status at any time prior to the induction attempt;
  • Ruptured membranes ≥ 48 hours prior to the start of treatment;
  • Suspected chorioamnionitis;

  • Any condition in which vaginal delivery is contraindicated e.g., placenta previa or any unexplained genital bleeding at any time after 24 weeks during this pregnancy;
  • Known or suspected allergy to misoprostol, other prostaglandins or any of the excipients;
  • Any condition urgently requiring delivery;
  • Unable to comply with the protocol.
