A Randomized Trial of Oral Misoprostol Alone Versus Oral Misoprostol Followed by Oxytocin for Labour Induction (MOLI)

December 13, 2024 updated by: University of Liverpool

A Randomized Trial Comparing Oral Misoprostol Alone with Oral Misoprostol Followed by Oxytocin in Women Induced for Hypertension of Pregnancy

The primary objective of the trial is to assess the following: In women who have undergone cervical preparation with oral misoprostol as part of labour induction for hypertensive disease in India, is augmentation using oral misoprostol superior to the standard protocol of intravenous oxytocin?

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Every year approximately 30 000 women die from hypertensive disease in pregnancy. Magnesium sulphate and anti-hypertensives reduce morbidity, but delivery is the only cure. Low dose oral misoprostol, a prostaglandin E1 analogue, is a highly effective method for labour induction. Usually, once active labour has commenced, the misoprostol is replaced with an intravenous oxytocin infusion. However, some studies have shown that oral misoprostol can be continued into active labour. In the Cochrane review on labour induction, those whose augmentation was continued with misoprostol (M/M protocol) had 42% less CSs than those who changed to oxytocin (M/Ox protocol; 15% vs 26%). This misoprostol-only protocol would be simpler and probably more acceptable to women. However, these two protocols have never been directly compared. We propose a pragmatic, open-label, randomised trial to compare an M/M labour induction protocol with the standard M/Ox protocol.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

    • Signed informed consent form
    • Undergone cervical ripening with misoprostol if cervix initially unfavourable

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Oxytocin infusion
  • Oxytocin infusion will be given through an electronic infusion pump. One unit of oxytocin will be injected in 500 mL of Ringer's lactate, started at a rate of 2 mU/min, and increased every 30 min by 2 mU/min until there are three to four contractions every 10 min. The rate will be titrated to maintain that contraction frequency. The maximum dose will be 20mU/min as oxytocin summary product characteristics.
  • The oxytocin group will not receive misoprostol after the membranes have ruptured.

Other Names:
  • Pitocin
Other: Oral misoprostol
  • An initial dose of misoprostol 25mcg will be given orally after randomisation (this must be a minimum of 2 hours after the previous misoprostol dose).
  • The next dose of oral misoprostol will be omitted if moderate or strong contractions are occurring at 3 in 10 minutes or more (i.e. 9 or more in the preceding 30 minutes)
  • If contractions subsequently reduce to less than 3 in 10 (under 9 in 30 minutes), or become irregular or mild, then the oral misoprostol 25mcg can be restarted
  • In the event of inadequate progress, clinicians will be advised to give further misoprostol if there are any concerns about contractions strength or frequency.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The data from this study will be confidential until the database is closed at the end of the study. Following this the study investigators will have exclusive access to the data until the publication of the results in a journal. Once this has happened, the database will be open to other researchers upon request. Open access databases will also be sought so as to maximise the availability of our research data with as few restrictions as possible, in line with MRC and Wellcome Trust policy. The consent form will include a clause for the woman to give permission for her anonymous data to be used for future research studies.

IPD Sharing Time Frame

The data will be released upon publication of the trial results. After this, the data will be shared on a public database to maximise the viability of the data.

IPD Sharing Access Criteria

Initially this will be upon request with later public publication of the data.
