E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety and tolerability of BYM338 in the treatment of sIBM and to further evaluate the effect of three BYM338 dose regimens against placebo in increasing the distance traveled as measured by the 6 Minute Walking Distance Test (6MWD). |
|
E.2.2 | Secondary objectives of the trial |
- To describe the long-term evolution of quadriceps muscle strength using quadriceps Quantitative Muscle Testing (QMT)
- To describe physical function reported by patients using the Sporadic Inclusion Body Myositis Functional Assessment (sIFA)
- To report the incidence of self-reported falls and self-reported injurious falls (falls that result in any subject injury) which are a subset of all self-reported falls
- To describe physical performance using the Short Physical Performance Battery (SPPB)
- To characterize muscle changes using magnetic resonance imaging (MRI) from a subset of patients
- To investigate the development of immunogenicity against BYM338 |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients who completed the core study
- Written informed consent must be obtained before any extension study assessment is performed
- Able to communicate well with the investigator
- Willing to participate for the entire duration of the extension study with commitment to follow study requirements and procedures. |
|
E.4 | Principal exclusion criteria |
- Women who are pregnant
- Women of child-bearing potential unless they are using highly effective methods of contraception during dosing and for 6 months after the last BYM338 dose
- Current use of prohibited treatments
- History of severe hypersensitivity reaction in the core study
- History of adverse event(s) (including those from the core study) prior to the start of study drug in the extension study that, in the judgment of the investigator, taking into account the subject’s overall status, prevent the subject from entering the extension study
- Clinically significant abnormal liver function tests
- Any medical condition or laboratory finding which, in the opinion of the investigator may interfere with participation in the study, might confound the results of the study, or pose an additional safety risk in administering BYM338
Other protocol-defined exclusion criteria may apply. |
