A Clinical Study of the Efficacy of Natalizumab on Reducing Disability Progression in Participants With Secondary Progressive Multiple Sclerosis (ASCEND in SPMS)

10 de agosto de 2017 atualizado por: Biogen

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Efficacy of Natalizumab on Reducing Disability Progression in Subjects With Secondary Progressive Multiple Sclerosis, With Optional Open-Label Extension

This is a Phase 3b, multicenter, international study conducted in 2 parts. Upon completion of the placebo-controlled period (Part 1), participants will have the option of enrolling in a 2-year open-label extension (Part 2).

Part 1: The primary objective of the study is to investigate whether treatment with natalizumab slows the accumulation of disability not related to relapses in participants with secondary progressive multiple sclerosis (SPMS).

The secondary objectives of Part 1 of this study are to determine the proportion of participants with consistent improvement in Timed 25-Foot Walk (T25FW), the change in participant-reported ambulatory status as measured by the 12-item MS Walking Scale (MSWS-12), the change in manual ability based on the ABILHAND Questionnaire, the impact of natalizumab on participant-reported quality of life using the Multiple Sclerosis Impact Scale-29 Physical (MSIS-29 Physical), the change in whole brain volume between the end of study and Week 24 using magnetic resonance imaging (MRI) and the proportion of participants experiencing progression of disability as measured by individual physical Expanded Disability Status Scale (EDSS) system scores.

Part 2: The primary objective of Part 2 of the study is to evaluate the safety profile of natalizumab in participants with SPMS.

The secondary objectives of Part 2 of the study are to investigate long-term disability (based on clinical or participant-reported assessments) in participants with SPMS receiving natalizumab treatment for approximately 4 years and to assess change in brain volume and T2 lesion volume.

  • SPMS defined as relapsing-remitting disease followed by progression of disability independent of or not explained by multiple sclerosis (MS) relapses for at least 2 years.
  • EDSS score of 3.0 to 6.5, inclusive.
  • Multiple Sclerosis Severity Score of 4 or higher.
  • Documented confirmed evidence of disease progression independent of clinical relapses over the 1 year prior to enrollment as defined in the Study Reference Guide.

Key Exclusion Criteria (Part 1):

  • Relapsing remitting multiple sclerosis (RRMS) or primary progressive MS as defined by the revised McDonald Committee criteria.
  • Clinical relapse (within 3 months) prior to randomization.
  • T25FW test of >30 seconds during the screening period.
  • Any value below the lower limit of normal for blood levels of leukocytes, lymphocytes, or neutrophils.
  • Considered by the Investigator to be immunocompromised based on medical history, physical examination, laboratory testing, or any other testing required by local guidelines, or due to prior immunosuppressive or immunomodulating treatment.
  • Subjects for whom MRI is contraindicated (i.e., have pacemakers or other contraindicated implanted metal devices, are allergic to gadolinium, or have claustrophobia that cannot be medically managed).
  • History of any clinically significant (as determined by the Investigator) cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic (other than MS), dermatologic, psychiatric, and renal, or other major disease that would preclude participation in a clinical study.
  • History of malignant disease, including solid tumors and hematologic malignancies (with the exception of basal cell and squamous cell carcinomas of the skin that have been completely excised and are considered cured).
  • Known history of or positive test result for human immunodeficiency virus.
  • Positive test result for hepatitis C virus (test for hepatitis C virus antibody or hepatitis B virus (test for hepatitis B surface antigen and/or hepatitis B core antibody).
  • History of transplantation or any anti-rejection therapy.
  • Presence of any infectious disease (e.g., cellulitis, abscess, pneumonia, septicemia) within 30 days prior to screening.
  • History of progressive multifocal leukoencephalopathy or other opportunistic infections.

Treatment History (Part 1)

  • Any prior treatment with cell-depleting therapies, including total lymphoid irradiation, cladribine, rituximab, alemtuzumab, or bone marrow ablation.
  • Any prior treatment with natalizumab.
  • Treatment with mitoxantrone, cyclophosphamide, cyclosporine, azathioprine, methotrexate, mycophenolate mofetil, T cell or T cell receptor vaccination, fingolimod, daclizumab, or cytapheresis within 6 months prior to randomization.
  • Treatment with intravenous or oral corticosteroids, intravenous immunoglobulin, or plasmapheresis for treatment of MS within the 3 months prior to randomization.
  • Treatment with glatiramer acetate or any interferon beta preparations within 4 weeks prior to randomization.
  • Treatment with 4-aminopyridine within 30 days prior to randomization, unless a stable dose has been maintained for at least 30 days prior to randomization and will be continued for the course of this study.

Key Inclusion Criteria (Part 2):

  • Subjects must have participated in and completed Part 1 per protocol, and have documented assessment attempts for EDSS, T25FW, and 9HPT prior to first open-label dosing.

Key Exclusion Criteria (Part 2):

  • Subjects with any significant change in clinical status, including laboratory tests that, in the opinion of the Investigator, would make them unsuitable to participate in this extension study. The Investigator must re-review the subject's medical fitness for participation and consider any diseases that would preclude treatment.
  • Subjects who discontinued study treatment in Part 1 OR had fewer than 20 infusions in Part 1 OR missed 2 or more consecutive infusions in Part 1.

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Part 1: Percentage of Participants With Confirmed Progression of Disability in One or More of the Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), or 9-Hole Peg Test (9HPT)
Prazo: Up to 96 weeks (2 years)

Confirmed disability progression, defined as ≥1 of the following criteria (confirmed at a second visit ≥6 months later and at Week 96):

  • Confirmed progression in EDSS (EDSS score increased from baseline [BL] by ≥1 point if BL EDSS ≤5.5 or by ≥0.5 points if BL EDSS ≥6);
  • Confirmed progression in T25FW (T25FW increased by ≥20% of the BL walk);
  • Confirmed progression in 9HPT (9HPT increased by ≥20% of the time taken at BL on either hand and confirmed on the same hand).

The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. The T25FW is a quantitative mobility and leg function performance test where the participant is timed while walking for 25 feet. The 9HPT is a quantitative test of upper extremity function that measures the time it takes to place 9 pegs into 9 holes and then remove the pegs.

Descrição da medida
Prazo
Part 1: Percentage of Participants With a T25FW Response
Prazo: Up to 96 weeks
T25FW response is defined as any improvement from the best pre-dose T25FW in at least 75% of the scheduled on-treatment visits through Week 96. The T25FW is a quantitative mobility and leg function performance test based on a timed walk over 25 feet. The participant is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The time is calculated from the initiation of the instruction to start and ends when the participant has reached the 25-foot mark. The task is immediately administered again by having the patient walk back the same distance. The score for the T25FW is the average of the 2 completed trials. The 95% CI of the percentage is based on normal approximation.
Up to 96 weeks
Part 1: Change From Baseline in the 12-Item MS Walking Scale (MSWS-12)
Prazo: Baseline and Week 96
MSWS-12 is a participant self-assessment of the walking limitations due to MS during the past 2 weeks. It contains 12 items that measure the impact of MS on walking. Items are summed to generate a total score and transformed to a scale with a range of 0 to 100, where higher scores indicate greater impact on walking. A negative number on change from BL value indicates an improvement in MSWS-12.
Baseline and Week 96
Part 1: Change From Baseline in Manual Ability Score Based on the ABILHAND Questionnaire
Prazo: Baseline and Week 96
The ABILHAND Questionnaire measures the participant's perceived difficulty in performing everyday manual activities in the last 3 months. The participant completes a 56-item questionnaire by estimating their own difficulty or ease in performing each of 56 activities. Items are summed to generate a total score and transformed to a scale with a range of 0 to 100, where high scores indicate greater impact on manual ability. A positive number on change from baseline value indicates an improvement in ABILHAND.
Baseline and Week 96
Part 1: Change From Baseline in the Multiple Sclerosis Impact Scale-29 Physical (MSIS-29 Physical) Score
Prazo: Baseline and Week 96
The 29-item MSIS-29 is a participant-reported outcome measure to assess the impact of MS on day-to-day life during the past 2 weeks from a participant's perspective; it measures 20 physical items and 9 psychological items. The physical score is generated by summing individual items and then transforming to a scale with a range of 0 to 100, where high scores indicate worse health. A negative number on change from baseline value indicates an improvement in MSIS-29.
Baseline and Week 96
Part 1: Percentage Change From Week 24 in Whole Brain Volume at Week 96
Prazo: Week 24 and Week 96

Week 24 and Week 96
Part 1: Percentage of Participants Defined as Confirmed Progressors on EDSS Functional System Scores
Prazo: Up to 96 weeks

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 met 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.

A confirmed progressor was defined as a participant who met the criteria for disability progression at any given visit and at the 6-Month Confirmation Visit. The 95% CIs are based on normal approximation.
Up to 96 weeks
Part 2: Percentage of Participants With Disability Worsening at 156 Weeks
Prazo: Week 156
Percentage of participants with disability worsening at each scheduled efficacy visit in Part 2, defined as one or more of the following: • ≥ 20% worsening from Part 1 baseline in T25FW; • ≥ 20% worsening from Part 1 baseline in 9HPT; • Worsening from Part 1 baseline in EDSS (≥ 1 point increase if Part 1 baseline EDSS ≤ 5.5 or ≥ 0.5 point increase if Part 1 baseline EDSS > 5.5). The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. The T25FW is a quantitative mobility and leg function performance test where the participant is timed while walking for 25 feet. The 9HPT is a quantitative test of upper extremity function that measures the time it takes to place 9 pegs into 9 holes and then remove the pegs. 95% CIs of percentages are based on normal approximation.

Part 2: Absolute Change From Baseline (Part 1) in T25FW
Prazo: Baseline (Part 1) and Weeks 156, 204
The T25FW is a quantitative mobility and leg function performance test based on a timed 25-foot walk. The participant is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The time is calculated from the initiation of the instruction to start and ends when the participant has reached the 25-foot mark. The task is immediately repeated; the score for the T25FW is the average of the two completed trials. Lower scores on time taken to reach 25 foot mark reflect a better outcome. Values are presented for the overall group, as well as the Confirmed Progressor (CP, defined in the primary outcome measure description above) and Non-Progressor (NP) subgroups.
