入选标准
- •- Relapsing forms of Multiple Sclerosis (RMS) - Cohort
- •i) Participants must have an Expanded Disability Status Scale (EDSS) of ≥ 3.0 and ≤ 5.
- •ii) Participants must have a diagnosis of Multiple Sclerosis (MS) with relapsed/refractory MS or conversion to active secondary progressive multiple sclerosis (aSPMS), and worsening of disease within 12 months prior to Screening and while on treatment with a high-efficacy DMT for at least 6 months.
- •- Progressive forms of MS - Cohort
- •i) Participants must have an EDSS ≥ 3.0 and ≤ 6.
- •ii) Participants must have a diagnosis of primary progressive multiple sclerosis (PPMS) that is treatment-resistant or diagnosis of inactive secondary progressive multiple sclerosis (iSPMS).
- •- Myasthenia Gravis - Cohort 3
- •i)MGFA classification of II-IV at screening
- •ii) Documentation of autoantibodies against AChR or MuSK (historical or at Screening)
- •iii) Refractory disease defined as disease activity on at least 2 immunosuppressants, including steroids, NSIs, or biologics.
- •iv) Has had thymectomy, only if indicated according to current guidelines.
排除标准
- •Cohorts 1 and 2: Participants that cannot complete the 9-Hole Peg Test (9-HPT) in at least 1 hand in <240 seconds unless extenuating medical conditions unrelated to MS prohibit this.
- •Participants that cannot perform a Timed 25-Foot Walk Test (T25FWT) in < 150 seconds.
- •Presence of other confounding peripheral nervous system disorders or other disorders that may impact muscle strength (eg, myositis) or cause weakness, stroke, chronic inflammatory demyelinating polyradiculoneuropathy, Lambert-Eaton myasthenic syndrome.
- •Other protocol-defined Inclusion/Exclusion criteria apply.
