抗ディファレンシエイト 20 (CD20) クラスター療法からユブリツキシマブに移行する際の有効性の維持を評価する研究 (ENHANCE)
抗CD20療法からユブリツキシマブに移行する際の有効性維持の評価
The primary purpose of this phase 3b study is to assess the efficacy of a modified regimen of ublituximab in participants with relapsing multiple sclerosis (RMS) as measured by T1 Gadolinium (Gd)-enhancing lesions in Part A; PK in Part B along with efficacy of ublituximab as measured by T1 Gd-enhancing lesions in participants who had a suboptimal experience on prior anti-CD20 therapy in Part C. The study consists of 3 parts: Part A is single-armed and open-label, Part B is randomized, double-blind, placebo-controlled, and Part C is single-armed and open-label.

-
Neurologically stable for > 30 days prior to first dose of ublituximab.
-
Female participants of childbearing potential must consent to use a medically acceptable method of contraception from consent, throughout the study period, and for 6 months after the last dose of ublituximab.
-
Part C: participants currently treated with an anti-CD20 agent for at least 6 months and meet the washout requirements prior to W1D1.
-
Part C: Discontinuation of current anti-CD20 must be due to suboptimal experience
Exclusion Criteria:
- History of any serious 3 Infusion Related Reaction (IRR) on prior anti-CD20 therapy.
- Primary-progressive multiple sclerosis (PPMS) or inactive Secondary Progressive MS (SPMS).
- Active chronic (or stable but treated with immune therapy) disease of the immune system other than MS (e.g., rheumatoid arthritis, scleroderma, Sjögren's syndrome, Crohn's disease, ulcerative colitis, etc.) or immunodeficiency syndrome (hereditary immune deficiency, drug-induced immune deficiency, etc.).
- Current evidence or known history of clinically significant infection, including: chronic, recurrent, or ongoing active viral, bacterial, or fungal infectious disease requiring long term systemic treatment such as, but not limited to chronic urinary tract infection, chronic pulmonary infection with bronchiectasis, tuberculosis, or active hepatitis C virus (HCV).
- Previous serious opportunistic or atypical infection.
- Evidence of chronic active or history of hepatitis B virus (HBV) infection as evidenced by a detectable hepatitis B surface antigen (HBsAg), or positive hepatitis B core antibody (HBcAb), or chronic hepatitis C infection. Participants with positive hepatitis C virus antibody (HCV Ab) are eligible only if polymerase chain reaction (PCR) is negative for HCV ribonucleic acid (RNA).
- History or evidence (clinical, radiological, or biomarker) of suspected or confirmed progressive multifocal leukoencephalopathy (PML).
- Receipt of any live or live-attenuated vaccines (including vaccines for varicella-zoster virus or measles) within 4 weeks prior to first study drug administration.
- Participants requiring treatment with intravenous immune globulin (IVIG) for decreased immunoglobulins within the 12 months prior to W1D1.
- Any active malignancies other than adequately treated basal, squamous cell or in situ carcinoma.
- Participants who have ever received ublituximab, alemtuzumab, cyclophosphamide, mitoxantrone, cladribine, or daclizumab (including for non-MS indications).
