Ocrelizumab Discontinuation in Relapsing Multiple Sclerosis

Recruiting now · Phase 4 · Has a placebo group

Conditions studied: Multiple Sclerosis

In brief

This study is a prospective, multi-center, randomized, double blinded, placebo-controlled study of OCR treatment-discontinuation in patients with early RMS. All eligible participants will be initiated on OCR using the standard approved administration schedule of two 300 mg infusions separated by 14 days (i.e., Days 0 and 14) for a total of 600 mg, followed by 600 mg infusions at Month 6,12, 18, and 24. At Month 24, participants will be randomized (2:1) to one of two Arms with randomized treatment beginning at Month 30: Arm 1: placebo infusions every 6 months; or Arm 2: OCR infusions every 6 months. The treatment period will be for a total of 48 months.

Who can join

Age: 18 and older, up to 55. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Have at least one clinical episode that satisfies McDonald 2017 criteria for early Multiple sclerosis (MS) with a dissemination in time that can be met clinically, by Magnetic Resonance Imaging (MRI), or based on oligoclonal band (OCB) positivity
• Have a length of disease duration, from first symptom, of ≤ 3 years at time of informed consent
• For women of childbearing potential: Agreement to remain abstinent (refrain from heterosexual intercourse) or use effective methods of contraception during the treatment period and for at least 6 months after the last dose of study drug:
• A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus)
• Examples of contraceptive methods include bilateral tubal ligation, male sterilization, established hormonal contraceptives that inhibit ovulation, hormone- releasing intrauterine devices, and copper intrauterine devices
• The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post ovulation methods) and withdrawal are not acceptable methods of contraception
• Barrier methods must always be supplemented with the use of a spermicide

You may not qualify if…

• Inability or unwillingness of a participant to give written informed consent or comply with study protocol
• History of primary progressive multiple sclerosis (PPMS), progressive relapsing multiple sclerosis (PRMS), or secondary progressive multiple sclerosis (SPMS)
• Any metallic material or electronic device in the body, or condition that precludes the participant from undergoing MRI
• Known presence or history of other neurological disorders, including but not limited to the following:
• Ischemic cerebrovascular disorders, including but not limited to transient ischemic attack, subarachnoid hemorrhage, cerebral thrombosis, cerebral embolism, or cerebral hemorrhage
• CNS or spinal cord tumor, metabolic or infectious cause of myelopathy, genetically inherited progressive CNS disorder, CNS sarcoidosis, or systemic autoimmune disorders potentially causing progressive neurologic disease or affecting ability to perform the study assessments
• Pregnancy or lactation
• Female participants of childbearing potential must have a negative urine pregnancy test at screening
• Any concomitant disease that may require chronic systemic treatment with corticosteroids or immunosuppressants during the course of the study
• Lack of peripheral venous access
• History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
• Significant, inadequately controlled (e.g., diagnostic evaluations indicated or change in medications warranted) disease, such as cardiovascular (including cardiac arrhythmia), pulmonary (including obstructive pulmonary disease), renal, hepatic, endocrine, and gastrointestinal or any other significant disease that in the opinion of the investigator may preclude participant from participating in the study
• Functional status of New York Heart Association (NYHA) Class III or higher for heart failure at the screening visit
• Known active bacterial, viral, fungal, mycobacterial infection or other infection (including tuberculosis (TB) or atypical mycobacterial disease but excluding limited superficial fungal or viral infections of the skin or nails) or any severe episode of infection requiring hospitalization or treatment with IV antibiotics within 4 weeks prior to Mo 0/Day 0 infusion or oral antibiotics within 2 weeks prior to Mo 0/Day 0 infusion
• Active or chronic infection with human immunodeficiency virus (HIV), syphilis or TB (see laboratory tests below)
• Evidence of past hepatitis B (including treated hepatitis B) or untreated hepatitis C infection (treated hepatitis C is not considered exclusionary). Hepatitis B surface antibody following hepatitis B immunization is not considered to be evidence of past infection (see laboratory tests below).
• Known active malignancy or active monitoring for recurrence of malignancy, including solid tumors and hematological malignancies, except basal cell, in situ squamous cell carcinoma of the skin, and in situ carcinoma of the cervix or the uterus that have been excised with clear margins
• Substance use disorder, including the recurrent use of alcohol and/or drugs within the past year associated with clinically significant impairment associated with failure to meet major responsibilities at work, school, or home
• Receipt of live or live-attenuated vaccines within 4 weeks prior to Mo 0/Day 0 infusion
• Contraindications to or severe intolerance of oral or IV corticosteroids, including IV methylprednisolone administered according to the country label, including:
• Psychosis not controlled by a treatment
• Hypersensitivity to any of the constituents or excipients of the preceding steroids
• Current or prior treatment with the following MS DMTs: fingolimod and other S1P receptor modulators, cladribine, natalizumab, anti-CD20 molecules, alemtuzumab, and chemotherapeutic agents
• Treatment with fumarates within 30 days prior to collection of Mo 0/Day 0 mechanistic samples, Mo 0/Day 0 MRI, and Mo 0/Day 0 infusion
• (a) Current or prior treatment with any approved or experimental immunomodulatory therapies, unless reviewed and approved by the SAC (Section 3.6), or (b) Treatment with any experimental procedure for MS (e.g., treatment for chronic cerebrospinal venous insufficiency)
