入选标准
- •-Study participant must be =18 to =89 years of age, at the time of signing the informed consent
- •-Study participant must be seropositive for leucine-rich glioma inactivated 1 (LGI1) antibody measured by LGI1 serum autoantibody cell-binding assay
- •-Study participant must have faciobrachial dystonic seizures (FBDS) and/or other partial [focal] seizures with or without secondary generalization (=2 seizures/week) during the Screening Period, or have experienced such seizures that stopped as a result of intravenous
- •methylprednisolone (IVMP) initiation
- •-Study participant is currently considered for treatment with IVMP by the investigator or has initiated IVMP treatment at a dose of 500 to 1000 mg/day within 14 days prior to randomization. If the study participant has initiated a steroid taper, the study participant cannot be receiving an
- •oral steroid dose lower than 60 mg/day when randomized
- •-Study participant with onset of disease between 0 to 12 months prior to Screening
- •-Study participant weighs at least 35 kg (for males and females) at Screening
- •-A male participant must agree to use contraception during the treatment period and for at least 90 days after the final dose of study treatment and refrain from donating sperm during this period
- •-A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
- •i) Not a woman of childbearing potential (WOCBP)
- •ii) A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 90 days after the final dose of study treatment
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 18
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 50
排除标准
- •-Study participant has a known hypersensitivity to any components of the study medication or any other anti-neonatal Fc receptor (FcRn) medications. This includes a known history of hyperprolinemia, since L-proline is a constituent of the rozanolixizumab formulation
- •-Study participant has a confirmed prior diagnosis of epilepsy that is unrelated to LGI1 autoimmune encephalitis (AIE)
- •-Study participant has active neoplastic disease or history of neoplastic disease within 5 years of study entry (except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the uterine cervix which has been definitively treated with standard of care approaches)
- •-Study participant has 12-lead electrocardiogram (ECG) with findings considered clinically significant upon medical review
- •-Study participant has current unstable liver or biliary disease, per investigator assessment, defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis
- •-Study participant has positive tuberculosis (TB) test at the Screening Visit
- •-Study participant has any of the following active gastrointestinal (GI) disorders: inflammatory bowel disease, GI ulceration, or diverticulitis
- •-Study participant has a history of solid organ transplant or hematopoietic stem cell transplant
- •-Study participant has undergone a splenectomy

- •-Study participant has previously received rozanolixizumab drug product
- •-Alanine transaminase (ALT), aspartate aminotransferase (AST), or alkaline phosphatase (ALP) are >2x upper limit of normal (ULN)
- •-Bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35 %)
- •-Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
- •-For randomized study participants with a Baseline result >ULN for ALT, AST, ALP, or total bilirubin but <1.5xULN, a Baseline diagnosis and/or the cause of any clinically meaningful elevation will have to be understood and recorded in the electronic case report form (eCRF)
- •-If study participant has >ULN for ALT, AST, or ALP that does not meet the exclusion limit at Screening, the tests should be repeated, if possible, prior to dosing to ensure there was no further ongoing clinically relevant increase. In case of a clinically relevant increase, inclusion of the study participants will have to be discussed with the medical monitor
- •-Tests that result in ALT, AST, or ALP up to 25 % above the exclusion limit (>2xULN) will have to be repeated once for confirmation. This includes rescreening
- •-Study participant has an IgG level =5.5 g/L at the Screening Visit
- •-Study participant has absolute neutrophil count <1500 cells/mm^3 at the Screening Visit
- •-Participant has QT interval corrected for heart rate using Fridericia’s formula (QTcF) >450 msec (for male participants) or QTcF >470 msec (for female participants) or QTcF >480 msec in participants with bundle branch block
