Study summary

This is a double-blinded, placebo controlled study of estriol pills versus placebo pills in relapsing remitting multiple sclerosis. The study treatment will be an added on to Copaxone injections in all subjects. The primary outcome measure is a reduction in relapses.

Read the detailed description

Multiple sclerosis (MS) relapses are known to be significantly decreased during pregnancy. This proposal will establish whether oral treatment with estriol, the major estrogen of pregnancy, induces a decrease in relapses in relapsing remitting multiple sclerosis (RRMS) subjects when used in combination with injectable Copaxone. Previously, in a pilot study, it has been demonstrated that treatment of RRMS subjects with oral estriol for six months resulted in a significant reduction in gadolinium enhancing lesions on serial brain MRIs (Annals of Neurology, 2002; 52:421-428) and caused a favorable shift in immune responses (Journal of Immunology, 2003; 171:6267-6274). This is an add-on study aiming to extend these previous findings by treating longer and focusing on clinical outcomes. The combination of Copaxone injection plus estriol pill (8 mg per day) will be compared to Copaxone injection plus placebo pill in a double blind trial. The duration of treatment will be two years and the primary outcome measure will be relapse rate. Other outcomes will include disability measures and brain MRI outcomes. Safety measures (blood tests and gynecologic evaluations) will also be followed and correlations will be made between serum estriol levels with efficacy and safety. The overall goal of this study will be the development of a new oral treatment, estriol, for RRMS.

What researchers measure

Primary outcomes

  1. Confirmed Relapse, Annualized Relapse Rate

    A confirmed relapse was defined as new neurological symptoms or worsening of pre-existing symptoms, lasting at least 48 hours in a subject who had been neurologically stable or improving in the previous 30 days, accompanied by objective change in the neurological examination (worsening of 0.5 points on the EDSS or worsening by 1.0 or more points on the pyramidal, cerebellar, brainstem or visual functional system scores), not due to fatigue alone and not associated with fever or infection.

    Time frame: 24 months

Secondary outcomes

  1. Relapse Event, Annualized Relapse Rate

    Met all criteria for relapse except not confirmed to have increase in EDSS by an independent examiner.

    Time frame: 24 months

  2. Confirmed Relapse, Probability of First Relapse

    Time frame: 24 months

  3. Relapse Event, Probability of First Relapse Event
