About this study

Official title: Extension of the CBYM338B2203 Phase IIb/III Study to Evaluate the Long-term Efficacy, Safety and Tolerability of Intravenous BYM338 in Patients With Sporadic Inclusion Body Myositis

This extension study will provide data to further evaluate the efficacy, safety, and tolerability of three doses of BYM338 and to assess the long-term effects of BYM338 in patients with sporadic inclusion body myositis. The extension study was planned to consist of a Screening epoch (to assess patient eligibility), followed by a Treatment Period 1 epoch (double-blind and placebo-controlled), and a Treatment Period 2 epoch (open-label). A Post-treatment Follow-up (FUP) epoch was also planned for patients who discontinued prematurely. Patients who complete the core study and qualify for this extension study entered Treatment Period 1 and continued on the study drug to which they were randomized in the core study (either to one of the three bimagrumab doses (1 mg/kg, 3 mg/kg, and 10mg/kg) or placebo) during Treatment Period 1. Thus, Treatment Period 1 was double-blind and placebo-controlled. Participants were to continue in Treatment Period 1 until the dose with the best benefit-risk profile was determined from the core study data and selected (duration of Treatment Period 1 was estimated to be between 6 and 8 months). Once the dose with the best benefit-risk profile was selected, all participants (including those who were receiving placebo) were planned to enter Treatment Period 2 and switch to open-label treatment with bimagrumab at the selected dose. The core study has been completed but since the core study did not meet the primary end point (no bimagrumab dose was identified based on the core study efficacy results) the extension study was terminated as per protocol/sponsor's decision; therefore, no patients had entered Treatment Period 2. Instead, all patients were to return for the End of Treatment Period 1 (EOT1) visit at their next scheduled visit. As per protocol, all patients who discontinued study medication during Treatment Period 1 for any reason, including due to the study having been stopped as per protocol/sponsor's decision, were to have entered and complete the 6-month FUP after their EOT1 visit.

Due to the nature of the design of the core and extension studies and termination of study medication in the extension study, the treatment duration for individual patients varied considerably. Consequently, the number of patients contributing data to the efficacy analyses at Week 104 and later timepoints was decreased.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and Deaths.

    Safety monitoring was conducted throughout the study. AEs starting on or after the day of first administration of extension study drug until last administration of study drug + 56 days are considered. SAEs starting on or after the day of first administration of extension study drug are considered. Deaths which occurred on or after the day of first administration of extension study drug are considered.

    Measured: to end of study (up to 14 months, including the 6-month treatment-free follow-up period)

  2. Change From Core Study Baseline in 6 Minute Walking Distance Test (6MWD)

    The 6MWD test measures the distance (in meters) that a participant can walk in a 6 minute time frame. A positive change from baseline indicates improvement. The efficacy analysis and time points were based on windowed visits relative to the first dose of the double-blind treatment in the core study.

    Measured: Core study baseline, weeks 52, 78, 104, and >=117

Secondary outcomes (6)
  1. Change From Core Study Baseline in Quadriceps Quantitative Muscle Testing (QMT) on the Right Side

    Quantitative Muscle Testing (QMT) was used to describe the long-term evolution of quadriceps muscle strength on the right side. The QMT was performed using the same portable fixed dynamometry (PFD) used in the core study. A negative change from baseline indicates deterioration. The efficacy analysis and time points were based on windowed visits relative to the first dose of the double-blind treatment in the core study.

    Measured: Core study baseline, week 52, week 78, week 104 and >=week 117

  2. Change From Core Study Baseline in Sporadic Inclusion Body Myositis (sIBM) Functional Assessment (sIFA) Score

    Self-reported physical function was assessed by a newly developed patient reported outcome named sporadic inclusion body myositis (sIBM) functional assessment (sIFA). The sIFA consists of 11 items scored on an 11 point numerical rating scale from 0 (no difficulty) to 10 (unable to do) across 3 domains: upper body functioning, lower body functioning and general functioning. Participants completed the assessment where the recall period was the past week prior to completing the patient reported outcome (PRO). The total score on the sIFA scale ranges from 0 (minimum) to 110 (maximum). Higher values represent a worse outcome. A positive change from baseline indicates deterioration. The efficacy analysis and time points were based on windowed visits relative to the first dose of the double-blind treatment in the core study.

    Measured: Core study baseline, week 52, week 78, week 104, and >=week 117

  3. Estimated Annual Number of Falls Per Participant Within Treatment Group

    Participants documented any fall occurrences in a paper diary during the study.

    Measured: Core baseline to end of extension double-blind treatment (up to a maximum of 32 months)

  4. Change From Core Study Baseline in Short Physical Performance Battery (SPPB) Score

    The SPPB evaluated lower extremities function by testing gait speed, ability to keep standing balance and time to rise from a chair five times. The sub-score for each test ranged from 0 to 4. The summary score, which was a summation of scores from the 3 tests, ranged from 0 to 12. An increase in score indicates improvement in physical performance. A negative change from baseline indicates deterioration. The efficacy analysis and time points were based on windowed visits relative to the first dose of the double-blind treatment in the core study.

    Measured: Core study baseline, week 52, week 78, week 104 and >=week 117

  5. Change in Muscles of the Thigh

    Magnetic resonance imaging (MRI) was planned to be used to characterize changes in muscles of the thigh in a subset of patients.

    Measured: up to 1 year, up to 2 years

  6. Number of Patients With Anti-BYM338 Antibodies

    Investigated the development of immunogenicity against BYM338.

    Measured: end of double-blind treatment (up to 8 months)
