Brief summary

The primary objectives of the study are to determine the incidence of serious adverse events (SAEs) in participants with relapsing forms of multiple sclerosis (MS) in routine clinical practice and to assess the overall long-term clinical effectiveness of Plegridy in participants with relapsing forms of MS in routine clinical practice. The secondary objectives of this study in this study population are to describe Plegridy prescription and utilization adherence patterns in routine clinical practice; to assess the specific long-term clinical effectiveness of Plegridy in participants with relapsing forms of MS in routine clinical practice; to monitor the safety and tolerability of Plegridy in routine clinical practice by assessing the incidence of adverse events (AEs) of flu-like symptoms (FLS), injection site reactions (ISRs), and AEs (including laboratory abnormalities) leading to treatment discontinuation; to assess the effect of FLS on participant-reported effectiveness of, and satisfaction with, prophylactic management using a FLS-Visual Analog Scale (FLS-VAS); to evaluate the change in health-related quality of life (HRQoL), FLS, FLS-VAS, healthcare resource consumption, and treatment adherence over time.

Inclusion criteria

Key Inclusion Criteria: * Patient with MS who is newly, or is currently, prescribed Plegridy according to local label including patients who participated in Study 105MS302 (NCT01332019) or Study 105MS303 (NCT01939002). * Patient willing and able to complete patient-reported outcomes (PRO) with minimal assistance. Key

Exclusion criteria

* Concurrent enrollment in any clinical trial of an investigational product. Participation in non-interventional study can be allowed as long as this participation does not interfere with this protocol or is likely to affect the subject's ability to comply with the protocol.

Design outcomes

Primary

MeasureTime frame
Safety as measured by the incidence proportion of SAEsUp to 5 years
Safety as measured by the incidence rate of SAEsUp to 5 years
Clinical no evidence of disease activity (NEDA) as measured by the proportion of participants with no relapsesUp to 5 years
Clinical NEDA as measured by the proportion of participants with no disability progressionUp to 5 years

Secondary

MeasureTime frameDescription
Relapse activity as measured by time to first relapseUp to 5 years
Relapse activity as measured by the proportion of participants with relapseUp to 5 years
Relapse activity as measured by the distribution of the number of relapsesUp to 5 years
Disability progression as measured by the proportion of participants with sustained progression for at least six monthsUp to 5 yearsDisability progression measured by the Expanded Disability Status Scale (EDSS). The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist. Participants with confirmed progression of disability in EDSS physical functional system scores will be defined as those who meet one of the following criteria: an increase of ≥ 1 point from baseline system score of ≥ 1 or an increase of ≥ 2 points from baseline system score of 0 in at least 2 physical functional systems, or an increase of ≥ 2 points from baseline system score of ≥ 1 or an increase of ≥ 3 points from baseline system score of 0 in any 1 physical functional system. Worsening must be confirmed on a subsequent examination using the same criterion in the same functional system(s) at least 6 months later.
Disability progression as measured by the time to sustained disability progression for at least six monthsUp to 5 years
Incidence proportion of non-serious AEs leading to treatment discontinuationUp to 5 years
Prescription and utilization patterns as measured by prescribed dosing frequencyUp to 5 years
Impact of the severity of FLS on the ability to successfully manage symptoms via prophylaxis as measured by the participant-reported FLS-VASUp to 5 years
Changes in FLS assessment and FLS-VAS over timeBaseline to 5 years
Changes in EuroQoL EQ-5D, 3-level (EQ-5D-3L) score over timeBaseline to 5 yearsThe EQ-5D-3L is a standardized instrument for use as a measure of health outcome. It is a health questionnaire that consists of 2 pages - the EQ-5D descriptive system (page 2) and the EQ visual analogue scale (EQ VAS) (page 3). The EQ-5D-3L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, extreme problems.
Treatment adherence as measured by changes in adherence over time as reported in the treatment adherence questionnairesBaseline to 5 yearsWhere pen/syringe collection is locally allowed, treatment adherence will also be assessed by the proportion of used auto-injector pens/pre-filled syringes out of the total number of pens/syringes prescribed.
Frequency of MS-related and non-MS-related physician visits, specialists' visits, use of physiotherapy, hospitalizations and lengths of stay, and emergency room/department visitsUp to 5 years
Incidence rate of non-serious AEs leading to treatment discontinuationUp to 5 years
Prescription and utilization patterns as measured by duration of Plegridy useUp to 5 years
Prescription and utilization patterns as measured by the primary reason for discontinuation of PlegridyUp to 5 years
Relapse activity as measured by annualized relapse rate (ARR)Up to 5 years
