Fampridine in MS Patients: A Cognition, Fatigue, Depression and Quality of Life Analysis

Fampridine in MS Patients: A Cognition, Fatigue, Depression and Quality of Life Analysis

Fampyra, a voltage-dependent potassium channel blocker, is indicated for the improvement of walking in adult patients with multiple sclerosis with walking disability (EDSS 4-7). The medicinal product has been authorized under a so-called "conditional approval" scheme. This means that further evidence on this medicinal product is awaited and this study aims to assess the effect of Fampyra, administered according to standard clinical practice, on cognition, fatigue and quality of life in patients with MS.

This clinical study is a multicenter, prospective, non-interventional, cohort study of MS patients receiving Fampyra in outpatient setting. Patients will be treated according to the local prescribing information of the study medication and routine medical practice in terms of visit frequency and types of assessments performed. The assignment of the patient to this therapeutic strategy is not decided in advance by the study protocol but falls within current practice and the prescription of Fampyra is clearly separated from the physician's decision to include the patient in the current study.

Since this is purely non-interventional study, primary data -which will be obtained prospectively during the study visits through patients' interview and patient reported outcomes or as performed per standard clinical practice- will mainly be employed.

The study will take place in Greece. Investigator's decision to prescribe Fampyra (according to the indication for treatment as defined in the summary of product characteristics, SmPC and the current clinical practice), should precede entry into the study.

Inclusion Criteria:

• Adult patient (≥18 years old) with MS.
• Patient receiving Fampyra® for walking disability (EDSS 4-7).
• Patient receiving stable doses of any Disease Modifying Treatment (DMT) for at least 3 months prior to study entry.
• Patients will receive Fampyra® in line with the approved Summary of Product Characteristics (SmPC).
• Patients for whom the decision to prescribe therapy with Fampyra according to the locally approved product's summary of product characteristics (SmPC) has already been taken prior to their enrollment in the study and is clearly separated from the physician's decision to include the patient in the current study.
• Patients must have signed an informed consent document.
• Patients must be able to read, understand and complete the study specific questionnaires.

Exclusion Criteria:

• Pregnant or lactating woman.

• Concurrent treatment with other medicinal products containing fampridine (4-aminopyridine).
• Concomitant treatment with medicinal products that are inhibitors of Organic Transporter 2 (OCT2), e.g., cimetidine.
• Patients who have received more than 1 dose of fampridine at the time of enrollment into the study.
• Patients that meet any of the contraindications to the administration of the study drug according to the approved SmPC.
• Patients who currently receive treatment with any investigational drug/device/intervention or have received any investigational product within 1 month or 5 half-lives of the investigational agent (whichever is longer) before the commencement of therapy with fampridine
