Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) | First dose of study drug in Study 303 to within 180 days of last dose (up to approximately 5.5 years) | 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. |
| Secondary | Annualized Relapse Rate (ARR) in the 205MS303 Treatment Period | Up to 4.6 years in the 303 study | 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. |
| Secondary | ARR in the 205MS301-303 Combined Study Period and 205MS301 Treatment Period | Up to 5.6 years combining 303 with the initial Study 301; Up to 1 year in the 301 study | 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 MS medications were excluded from the analyses. ARR was adjusted for relapse rate, IFN beta use, EDSS (\<=2.5 vs \>2.5) and age (\<=35 vs \>35) prior to start of study treatment in 301, calculated using the negative binomial model. |
| Secondary | Number of Participants With Relapse in the 205MS303 Treatment Period | Up to 4.6 years in the 303 study | 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. |
| Secondary | Number of Participants With Relapse in the 205MS301-303 Combined Study Period | Up to 5.6 years combining 303 with the initial Study 301 | 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. |
| Secondary | Number of Participants With Sustained Disability Progression in the 205MS303 Treatment Period | Up to 4.6 years in Study 303 | Sustained disability progression is defined as at least a 1.0-point increase on the Expanded Disability Status Scale (EDSS) from 303 baseline EDSS ≥1.0 that is sustained for 24 weeks, or at least a 1.5-point increase on the EDSS from 303 baseline EDSS of 0, that is sustained for 24 weeks. The EDSS measures the disability status of people with multiple sclerosis on a scale that ranges from 0 to 10. The range of main categories include (0) =normal neurologic exam; to (5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS. Higher scores indicate more disability. |
| Secondary | Number of Participants With Sustained Disability Progression in the 205MS301-303 Combined Study Period | Up to 5.6 years combining 303 with the initial Study 301 | Sustained disability progression is defined as at least a 1.0-point increase on the Expanded Disability Status Scale (EDSS) from 303 baseline EDSS ≥1.0 that is sustained for 24 weeks, or at least a 1.5-point increase on the EDSS from 303 baseline EDSS of 0, that is sustained for 24 weeks. The EDSS measures the disability status of people with multiple sclerosis on a scale that ranges from 0 to 10. The range of main categories include (0) =normal neurologic exam; to (5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS. Higher scores indicate more disability. |
| Secondary | Number of Participants With New or Newly Enlarging T2 Hyperintense Lesions in the 205MS303 Treatment Period | Baseline 303, Weeks 48, 96, 144, 192, 240 in Study 303 | T2 Hyperintense Lesions were assessed by magnetic resonance imaging (MRI) and were analyzed by a central MRI reader. The number of participants with New or Newly Enlarging T2 Hyperintense Lesions relative to the 303 Baseline in the 303 Treatment Period is reported. |
| Secondary | Number of Participants With New or Newly Enlarging T2 Hyperintense Lesions in the 205MS301 Treatment Period | Baseline 301, Weeks 24, 96, 144 in Study 301 | T2 Hyperintense Lesions were assessed by MRI and were analyzed by a central MRI reader. The number of participants with New or Newly Enlarging T2 Hyperintense Lesions relative to the 301 Baseline in the 301 Treatment Period is reported. |
| Secondary | Number of Participants With Gadolinium-enhancing (Gd+) Lesions in the 205MS303 Treatment Period | 301-303: Baseline 303, Weeks 48, 96, 144, 192, 240; 203-303 and 302-303: Week 96 | Gd+ lesions were evaluated by MRI and were analyzed by a central MRI reader. |
