Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product. A SAE is any untoward medical occurrence or effect that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability / incapacity, is a congenital anomaly / birth defect or is medically important due to other reasons than the above mentioned criteria.
Time frame: First dose of study drug in Study 303 to within 180 days of last dose (up to approximately 5.5 years)
Annualized Relapse Rate (ARR) in the 205MS303 Treatment Period
Relapses are defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Study Neurologist. The unadjusted ARR was calculated by tabulating the total number of relapses experienced in the group divided by the number of days up to the end of study, and the ratio then multiplied by 365.25. Relapses that occurred after participants received alternative multiple sclerosis (MS) medications were excluded from the analyses. ARR was adjusted for relapse rate, IFN beta use, Expanded Disability Status Scale (EDSS) (\<=2.5 vs \>2.5) and age (\<=35 vs \>35) prior to start of study treatment in 205MS301, calculated using the negative binomial model.
Time frame: Up to 4.6 years in the 303 study
