Vaginal Estriol in Multiple Sclerosis

Phase 2

Completed

Conditions: Neurogenic Bladder
Multiple Sclerosis

Interventions: Drug: vaginal estriol

Registration Number: NCT03774407

Lead Sponsor: Texas Tech University Health Sciences Center

Brief Summary: Study to evaluate the efficiency of vaginal estriol, as a treatment for urogenital symptoms in female patients with RRMS. The secondary objective is to evaluate the potential role of vaginal estriol in re-myelination in RRMS patients.

Detailed Description: Pilot project to determine the effectiveness of 1 mg transvaginal estriol, as an adjunctive therapy for female MS patients. The goal is to recruit 20 patients from the MS clinic in the neurology department of Texas Tech University Health Sciences Center. This study has been planned in collaboration with reproductive endocrinology, endocrinology, gynecology and basic science. The 1mg transvaginal dose was chosen after careful search of the literature and consultation with collaborators.

Single-group pilot study.

Subjects:

Patients with relapsing remitting MS and urogenital symptoms (frequency, urgency, frequent urinary tract infections, incontinence) will be invited to participate in the study. Enrollment will be during their scheduled clinic appointment. Some candidates (patients of the primary investigator) may be contacted by phone and invited to participate in the study.

The clinical trial will be explained to potential participants in detail, reviewing the objectives and methodology of the study. There will be adequate time allotted to answer any questions or concerns from the potential participants. Those patients interested in participating in the study will be asked to sign the consent form. In order to remind patients about their follow-up visits, lab work, etc., they will be contacted routinely. Participants will be instructed to call in case of questions or concerns.

Patients will be evaluated clinically during their scheduled follow up in which a full neurological exam will be performed during each visit. Patients will be instructed by the primary investigator how to correctly use the vaginal cream. This will be done at their enrolment and reinforced by the principal investigator, during their follow up visits.

Primary Outcome Measures

Name	Time	Method
Change in Bladder Control Scale (BLCS)	baseline and 9 months	The questions are regarding control of the bladder, number of accidents in the past 4 weeks, alteration of activities because of bladder problems and restriction on lifestyle because of bladder problems. The total score for the BLCS is the sum of the scores for the 4 items. Scores can range from 0-22, with higher scores indicating greater bladder control problems. Change from baseline at 9 months.
Change in Visual Evoked Potential and Ocular Tomography Results From Baseline to 9 Months of Both Eyes	Baseline and 9 months	visual evoked potential measured in each eye at baseline and 9 months normal value should be bellow 100 milliseconds
Change in MS Quality of Life Questionnaire at Baseline and 9 Months. (Physical Score)	Quality of life score at baseline and Quality of life score at 9 months	Multiple sclerosis quality of life questionnaire is an extensive questionnaire filled by the patient and graded by physician. It consists of 2 main areas the physical health which include physical function, health perceptions, energy fatigue, role limitations, pain, sexual function, social function and health distress. The mental health score which includes health distress, overall quality of life, emotional wellbeing, role limitations and cognitive function. The physical health and mental health parts each include a possible score range of 0-100. Overall the lower the score the better
