Safety and Tolerability of Interferon-Beta-1a and Estroprogestins Association in MS Patients
Safety and Tolerability of Interferon-Beta-1a and Estroprogestins Association in MS Patients
Clinical and experimental evidences suggests an immunomodulatory effect of sex hormones in
 multiple sclerosis.

 The role of oral estroprogestins in the pathogenesis and in the clinical course of the
 disease is actually unknown.

 The aim of the study is to investigate safety and tolerability of association of
 estroprogestins in two different doses with interferon-beta 1a in patients with
 relapsing-remitting multiple sclerosis.
Phase 2, randomised, single blind, three arms study.

 Follow-up of 24 months.

 The study will include relapsing-remitting multiple sclerosis female patients.

 Patients will be equally randomised into three groups: 1) patients treated with IFN-beta 1a
 (44 mcg for three times a week), 2) patients treated with IFN-beta 1a and lower-dose
 estroprogestins (desogestrel 150 mcg, etinilestradiol 20 mcg), 3) patients treated with
 IFN-beta 1a and higher-dose estroprogestins (desogestrel 25 mcg, etinilestradiol 40 mcg).

 Safety and tolerability of the treatment will be evaluated using neurological examination and
 MRI analysis.

 A complete neurological examination (with EDSS) will be performed at month 0, 6, 12, 18 and
 24.

 MRI examination will be assessed at baseline and at month 12 and 24. In the same day of MRI
 examination we'll collect blood samples for hormonal analysis (we'll measure sex hormones in
 the follicular and in the luteal phase of a single menstrual cycle).

 During the follow-up patients will be evaluated also with: MS-Functional Composite at month
 0, 6, 12, 18, 24; neuropsychological evaluation at month 0, 12, 24; Fatigue Severity Scale at
 month 0, 12, 24; Hamilton Depression Scale at month 0, 12, 24; Quality of Life scale
 (MSQOL54) at month 0, 12, 24.
