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

This prospective double-blind, randomized, clinical trial, will be conducted at Ain Shams University Maternity Hospital.

Patients fulfilling inclusion and exclusion criteria will be divided into two groups.

Group (A):

181 women will receive three tablets of letrozole (On December 28, 2005, the U.S. Food and Drug Administration approved letrozole tablets (Femara®, made by Novartis Pharmaceuticals Corp.) as a single dose, each tablet 2.5 mg (total dose 7.5 mg per day) for two days at home and will be told to bring back the empty packs. The third dose will be given on admission to hospital on day three and will be followed by 400 mcg vaginal misoprostol soaked with saline every three hours up to maximum five doses on Day 3.

Group (B):

181 women will receive three tablets of placebo (manufactured by Egyptian Group Company for drug industries) as a single dose, for two days at home and will be told to bring back the empty packs. The third dose will be given on admission to hospital on day three and will be followed by 400 mcg vaginal misoprostol soaked with saline every three hours up to maximum five doses on Day 3.

Data recording:

  1. Duration of complete abortion.
  2. Post abortion bleeding.
  3. Incomplete delivery of the placenta necessitates evacuation under anesthesia.
  4. Hemoglobin and hematocrit after 24 hours from abortion to estimate the decrease in hemoglobin level.
  5. Recording maternal morbidities.
  6. Patients that will receive 5 doses and did not abort till 24 hours from the first dose of misoprostol will be considered failed induction and will stop follow up without reporting outcome.

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.
