Relapsing Remitting Multiple Sclerosis

Brief summary

This is a randomized, double-Blind, placebo-controlled Phase 2 Study of Orelabrutinib in Patients with Relapsing-Remitting Multiple Sclerosis.

Detailed description

The study contains 2 parts: Core Part and an Open-label Extension (OLE) Part. The Core Part is a randomized, double-blind, placebo-controlled, phase 2 study. Patients with RRMS will be randomly assigned to 1 of 4 treatment groups. placebo, orelabrutinib (low dose), orelabrutinib (medium dose) and orelabrutinib (high dose) at a 1:1:1:1 ratio. The OLE part is an open-label, single treatment arm study to enroll patients who have completed the Week 24 visit in the Core Part for continued treatment and collect additional long-term safety and efficacy data.All patients will receive the low dose of orelabrutinib or any other dose as suggested from the Core part of the study.

Are neurologically stable for ≥ 30 days prior to both Screening and Baseline. 4. One or more documented relapses within the 2 years before Screening 5. Have an EDSS score of 0 to 5.5 at Screening and Baseline (Day 1) 6. Women of childbearing potential must use effective method of contraception 7. Signed and dated informed consent 8. Patient currently participating in the Core Part who has completed the end of treatment visit and will be benefit from continued treatment per investigator's assessment. (OLE Part only)

Exclusion criteria

1. Diagnosed with progressive MS. 2. Disease duration \> 10 years in participants with an EDSS ≤ 2.0 at Screening and Baseline (Day 1). 3. Immunologic disorder other than MS. 4. History or current diagnosis of other neurological disorders that may mimic MS. 5. History or current diagnosis of progressive multifocal leukoencephalopathy (PML). 6. History of myocardial infarction or cerebrovascular event within 6 months prior to Screening, 7. A history of attempted suicide within 6 months prior to Screening or a positive response to items 4 or 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) at Screening. 8. An episode of major depression within the last 6 months prior to Screening (clinically stable minor depression is not exclusionary). 9.

Participants are excluded from participation in the study if taken prohibited medications/treatments. 12. Participation in any investigational drug study within 6 months or 5 half-lives of the investigational drug, whichever is longest, prior to Screening. 13.

Patient who has new abnormality appeared in the Core Part. (OLE Part only) 15. Any significant change in the subject's medical history that would preclude administration of the study drug. (OLE Part only) 16. Clinically significant laboratory abnormalities from the most recently available test in the Core Part that would preclude administration of the study drug. (OLE Part only)
