|Condition or disease||Intervention/treatment||Phase|
|Cervical Priming||Drug: misoprostol Drug: placebo||Phase 2|
Prior to the hysteroscopy procedure, study staff will record the type of procedure that will be conducted and the desired cervical dilatation. The study drug will be removed in the office and then a vaginal examination will be performed for signs of irritation or trauma. The diameter of the internal os will then be assessed using Hegar dilators. The diameter of the internal os will be assessed by the largest size of Hegar dilator that can be inserted into the internal os without resistance. If the subject requires further dilatation prior to the procedure, this will be noted; additional dilatation is per clinician preference. The use of a tenaculum to allow insertion of the dilator(s)/ hysteroscope should be recorded. The time of starting and ending the hysteroscopy procedure will be documented. The start time of the hysteroscopy procedure is taken from the time of insertion of the first Hegar dilator to completion of the hysteroscopy procedure. Cervical priming assessment and safety will be recorded.
The subject will attend the clinic for follow-up assessments 7 days after the procedure.
Adverse events and concomitant medications will be recorded throughout the study.
The study will use an adaptive design, beginning with the MVPI 400 mcg and escalating or reducing the dose depending on results seen with a particular dose.

Experimental: Misoprostol vaginal priming insert (MVPI)
One vaginal insert administered 18 - 24 hours prior to the scheduled hysteroscopy clinic visit. The initial dose is 400 mcg and dose will be adjusted between 100 - 1600 mcg after each study cohort based on safety and efficacy criteria as assessed by the Data and Safety Monitoring Board (DSMB).
One vaginal insert containing 100, 200, 400, 800, 1200, 1600 mcg misoprostol administered intravaginally one time and remain in place for 18 - 24 hours prior to the hysteroscopy procedure. An adaptive design will be used to determine whether to escalate or reduce the dose, starting with MVPI 400 mcg.
Placebo Comparator: MVPI Placebo
One vaginal insert of placebo administered 18 - 24 hours prior to the scheduled hysteroscopy clinic visit.
- Change in Diameter of the Internal Cervical os From Baseline (Pre-treatment) to Just Prior to the Hysteroscopy Procedure (Post-treatment). [ Time Frame: Baseline to 18-24 hours ]
- Percent of Women Requiring Further Dilatation in Order to Allow Uterine Access [ Time Frame: 18 - 24 hours ]
- Total Procedure Time From Insertion of the First Hegar Dilator to Completion of the Hysteroscopy Procedure; [ Time Frame: 18 - 24 hours ]
- Physician Assessment of Ease of Cervical Dilation; [ Time Frame: 18 - 24 hours ]
- Percentage of Participants With Adverse Events [ Time Frame: 9 days ]
