August 15, 2018 updated by: mohammed mahmoud samy, Ain Shams University

Efficacy of Prophylactic Vaginal Progesterone in Prevention of Preterm Delivery in Women With Placenta Previa

This study evaluates the efficacy of prophylactic vaginal progesterone administration in reducing of the episodes of antepartum hemorrhage and subsequent prevention of preterm delivery in women with placenta previa.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

Eligible women who consent to participate in the study are randomly allocated into one of the two study groups. Women who are allocated to the study group will receive vaginal progesterone 400 mg [Prontogest® vaginal pessaries 400, Marcyrl, Cairo, Egypt], once at bed time starting from 26-28 weeks of gestation and till 36 weeks of gestation or delivery (which is closer); while the other group will serve as controls. Patients will be followed up till delivery for the incidence in antepartum hemorrhagic episodes.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 40 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  1. Gestational age 26-28 weeks of gestation.
  2. Definite and reliable diagnosis of placenta previa (defined as presence of a placenta within 2 cm of the internal os), using a transvaginal ultrasound scan.

Exclusion Criteria:

  1. Multiple pregnancy.
  2. Women at high risk of preterm labor e.g. history of spontaneous preterm labor or preterm prelabor rupture of the membranes (PPROM).
  3. Severe antepartum hemorrhage and/or hemodynamic instability that necessitates urgent intervention and delivery.
  4. Women who have been maintained on progestin therapy since early pregnancy for whatever reason.
