Brief Summary

Official Title: “Phase 3 Study of Progesterone vs Placebo Therapy”

Condition Keyword(s):

There is considerable evidence to suggest that natural progesterone has anti-seizure properties. The purpose of this study is to determine if progesterone supplement during the second half of the menstrual cycle lessens seizure frequency in women with epilepsy.

Study Type: Interventional

Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Safety/Efficacy Study

Study Primary Completion Date: May 2010

Detailed Clinical Trial Description

This is a 6-month study. The first 3 months will gather baseline information on seizures, antiepileptic drug levels , menstrual cycles, hormone levels, emotional function, and quality of life. The second 3 months will assess the effects of treatment on these parameters.

  • Biological: Natural Progesterone
    • 200mg Progesterone Lozenges and Matched Placebo Lozenges

Arms, Groups and Cohorts in this Clinical Trial

  • Experimental: 1
    • Progesterone Lozenges
  • Placebo Comparator: 2
    • Matched Placebo
