En undersøgelse til evaluering af sikkerheden, tolerabiliteten og effektiviteten af BIIB017 (Peginterferon Beta-1a) hos pædiatriske deltagere til behandling af recidiverende-remitterende multipel sklerose
Et åbent, randomiseret, multicenter, aktivt kontrolleret, parallelgruppestudie til evaluering af sikkerheden, tolerabiliteten og effektiviteten af BIIB017 hos pædiatriske forsøgspersoner i alderen 10 til under 18 år til behandling af recidiverende-remitterende multipel sklerose Open-label udvidelse
This study will evaluate the safety, tolerability, and descriptive efficacy of BIIB017 in pediatric participants with relapsing-remitting multiple sclerosis (RRMS) and to assess the pharmacokinetics (PK) of BIIB017 in pediatric participants with RRMS in Part 1. In Part 2, the study will evaluate the long-term safety of BIIB017 and further describe safety and the long-term multiple sclerosis (MS) outcomes after BIIB017 treatment in participants who completed the study treatment at Week 96 in Part 1 of the study.

Beskrivelse
Key Inclusion Criteria:
Part 1:
- Must have a diagnosis of RRMS as defined by the revised consensus definition for pediatric MS.
- Must have an EDSS score between 0.0 and 5.5.
- Must have experienced >= 1 relapse in the 12 months prior to randomization (Day 1) or >= 2 relapses in the 24 months prior to randomization (Day 1) or have evidence of asymptomatic disease activity (Gd-enhancing lesions) on brain MRI in the 6 months prior to randomization (Day 1).
Part 2:
• Participants who completed the study treatment in Part 1 (Week 96 Visit), as per protocol.
Key Exclusion Criteria:
Part 1:
- Primary progressive, secondary progressive, or progressive relapsing MS. These conditions require the presence of continuous clinical disease worsening over a period of at least 3 months. Participants with these conditions may also have superimposed relapses but are distinguished from relapsing participants by the lack of clinically stable periods or clinical improvement.
- History of severe allergic or anaphylactic reactions or known drug hypersensitivity.
- Known allergy to any component of Avonex or BIIB017 formulation.
- Occurrence of an MS relapse that has occurred within 30 days prior to randomization (Day 1) and/or the participant has not stabilized from a previous relapse prior to randomization (Day 1).
- Any previous treatment with PEGylated human IFN β-1a.
Part 2:
- Any significant changes in medical history occurring after enrollment in Part 1, including laboratory test abnormalities or current clinically significant conditions that, in the opinion of the Investigator, would have excluded the participant's participation in Part 1. The Investigator must re-assess the participant's medical fitness for participation and consider any factors that would preclude treatment.
- The participant could not tolerate BIIB017 in Part 1.
NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

|
Part 1: Annualized Relapse Rate (ARR) at Week 48
Tidsramme: Week 48
|
A multiple sclerosis (MS) relapse is defined as the onset of new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings. ARR is calculated as the total number of relapses in each treatment group adjusted for the duration of study treatment in person-years. |

Part 2: Percentage of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and AEs Leading to Study Treatment Discontinuation
Tidsramme: From Week 96 to Week 196
|
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can 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, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, or is a medically important event. |

Part 1: ARR at Week 96
Tidsramme: Week 96
|
An MS relapse is defined as the onset of new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings. ARR is calculated as the total number of relapses in each treatment group adjusted for the duration of study treatment in person-years. |

Part 1: Change from Baseline in Cognition at Weeks 24, 48, 72, and 96 as Measured by the Symbol Digit Modality Test (SDMT)
Tidsramme: Baseline, Weeks 24, 48, 72, and 96
|
The SDMT measures the time to pair abstract symbols with specific numbers. The test requires elements of attention, visuoperceptual processing, working memory, and psychomotor speed. The score is the number of correctly coded items from 0 (worst) to 110 (best) in 90 seconds. The total score provides a measure of the speed and accuracy of symbol-digit substitution. Higher scores indicate better performance. |

Part 1: Change from Baseline in the Expanded Disability Status Scale (EDSS) Score at Weeks 48 and 96
Tidsramme: Baseline, Weeks 48, and 96
|
EDSS is based on a standardized neurological exam and focuses on symptoms that commonly occur in MS. Scores range from 0.0 (normal) to 10.0 (death due to MS). |

Part 1: Change from Baseline in the Quality of Life as Measured by the Pediatric Quality of Life Inventory (PedsQL) at Weeks 24, 48, 72 and 96
Tidsramme: Baseline, Weeks 24, 48, 72 and 96
|
The PedsQL consists of 23 items in four generic score scales: physical functioning, emotional functioning, social functioning, and school functioning that measures health related quality of life. The questionnaire asks how much of a problem each item has been during the past month. Each item is answered on a scale of 0 (never) to 4 (almost always) then the scores are transformed to a 0 to 100 scale, so that higher scores indicate better heath related quality of life. |

Part 1: Percentage of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs Leading to Study Treatment Discontinuation
Tidsramme: Up to Week 100
|
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can 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, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, or is a medically important event. |

Tidsramme: Baseline, Weeks 24, 48, 72, 96, and 100
|
Assessment of Tanner stages (a scale of physical development) will be performed by a medical doctor experienced with this assessment. Tanner score ranges from Stage 1 (childhood) to Stage 5 (full physical maturity). Information regarding Tanner staging will be collected for all male participants with bone age less than (<) 16 years and for female participants who are pre-menarche and have a bone age < 16 years and will be stopped once the participant's bone age reaches greater than or equal to (>=) 16 years or (once the participant is post-menarche. Tanner Score can be omitted if required by country-specific regulations and/or local ethics committees. |

MINI-KID is a short (approximately 15 minute) structured diagnostic interview used to assess the presence of 20 diagnostic and statistical manual of mental disorders, 4th Edition (DSM-IV) child and adolescent psychiatric disorders as well as the risk of suicide. The MINI-Kid frames questions in language that is easy for children and adolescents. It consists of 137 questions across 24 modules. |

Part 2: ARR at Weeks 144 and 192
Tidsramme: Weeks 144 and 192
|
An MS relapse is defined as the onset of new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings. ARR is calculated as the total number of relapses in each treatment group adjusted for the duration of study treatment in person-years. |
