A PHASE III RANDOMIZED DOUBLE-BLIND PLACEBO-CONTROLLED MULTICENTER STUDY TO EVALUATE THE EFFICACY SAFETY PHARMACOKINETICS AND PHARMACODYNAMICS OF SATRALIZUMAB AS MONOTHERAPY OR IN ADDITION TO BASELINE THERAPY IN PATIENTS WITH MYELIN OLIGODENDROCYTE GLYCOPROTEIN ANTIBODY-ASSOCIATED DISEASE (MOGAD)
Are you eligible to participate in this study?
You may be eligible for this study if you meet the following criteria:
-
Conditions: Myelin Oligodendrocyte Glycoprotein Antibody-associated Disease (mogad)
-
Age: Between 12 Year(s) - 99 Year(s)
-
Gender: Male or Female
-
Other Inclusion Criteria:
- Able to provide written informed consent form. If participant is under 18 years old, they must be able to provide assent and their parent/legal guardian must be able to provide consent
- Confirmed diagnosis of MOGAD meeting the following criteria:
- Documented history of =MOGAD attacks (first attack and at least 1 relapse) manifesting with the following presentations/syndromes: optic neuritis; transverse myelitis; acute disseminated encephalomyelitis (ADEM); other brain, brainstem, or cerebellar syndrome compatible with demyelination; and any combination of the above
- Diagnosis of MOGAD attacks based on the new or worsening, acute neurologic symptoms with an objective change on neurologic and/or ophthalmologic examination that persisted for more than 24 hours, AND
- Serum positivity for MOG-IgG by a CBA, AND
- Exclusion of alternative diagnoses, including MS
- Confirmed serum positivity for MOG-IgG at screening as assessed by a central laboratory
- Body weight =20kg at screening
- Expanded Disability Status Scale (EDSS) score of 0 - 6.5 at screening
- BCVA better than 20/800 in both eyes at screening
- History of =1 MOGAD relapse in the 12 months prior to screening or =2 attacks (may include the first attack) in the 24 months prior to screening
- Participants receiving either no ongoing chronic IST for MOGAD at the time of screening or receiving ongoing treatment with azathioprine (AZA), mycophenolate mofetil (MMF), oral corticosteroid (OCS) or a combination of AZA or MMF and OCS prior to screening
- Participants entering the study on a stable dose of AZA or MMF alone or in combination with OCS must have experienced at least one MOGAD attack prior to screening while using AZA or MMF for =3 months
- No contraindications to corticosteroids and at least one of the two other rescue treatments (IVIg or PLEX)
- No contraindications to MRI
- For women of childbearing potential: participants who agree to remain abstinent (refrain from heterosexual intercourse) or use adequate contraception during the treatment period and for at least 3 months after the final dose of satralizumab
You may not be eligible for this study if the following are true:
-
- Presence of AQP4-IgG in the serum
- History of encephalitis unrelated to MOGAD
- Dawson’s finger-type T2/FLAIR hyperintense lesions
- Participants who have experienced a MOGAD relapse within 12 weeks prior to baseline, unless their EDSS is 0 at screening
- Any concomitant disease other than MOGAD that may require treatment with ISTs or OCS or IV corticosteroids at doses >20 mg prednisone equivalent per day for >21 days during the study
- Participants who are pregnant or breastfeeding, or intending to become pregnant during the study or within 3 months after the final dose of satralizumab
- Participants who have any surgical procedure (except for minor surgeries defined as procedures requiring only local anesthesia or conscious sedation and are done on an ambulatory/outpatient basis; e.g., toenail surgery, mole surgical excision, tooth extraction) within 4 weeks prior to baseline
- Participants who are planning to have surgical procedure (except minor surgeries) during the study
- Participants with active or presence of recurrent bacterial, viral, fungal, mycobacterial infection, or other infection (excluding fungal infection of nail beds or dental caries) at baseline
- Infection requiring treatment with IV anti-infective agents within 4 weeks prior to baseline
- Evidence of progressive multifocal leukoencephalopathy
- Participants with evidence of latent or active tuberculosis (TB)
- Participants with positive screening tests for hepatitis B
- Participants with positive screening test for hepatitis C
- Participants with congenital or acquired immunodeficiency, including HIV infection
- Receipt of live or live attenuated vaccine within 6 weeks prior to baseline
- History of diverticulitis or concurrent severe gastrointestinal (GI) disorders (such as symptomatic diverticulosis) that, in the investigator's opinion, may lead to increased risk of complications such as GI perforation
- History of blood donation (1 unit or more), plasma donation or platelet donation within 90 days prior to screening
- History of malignancy within the last 5 years prior to baseline, including solid tumors, hematologic malignancies and in situ carcinoma
- History of severe allergic reaction to a biologic agent (e.g., shock, anaphylactic reactions)
- History of drug or alcohol abuse within 1 year prior to baseline
- Active suicidal ideation within 6 months prior to screening or history of suicide attempt within 3 years prior to screening
- Participants who have had any serious medical condition or abnormality in clinical laboratory tests that, in the investigator's judgment, precludes an individual's safe participation in and completion of the study
- Laboratory test findings are outside the acceptable ranges
