Multiple Sclerosis Clinical Trial

Ocrelizumab Discontinuation in Relapsing Multiple Sclerosis

Summary

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 and Month 12. At Month 12, participants will be randomized (1:1:1) to one of three Arms with randomized treatment beginning at Month 18: Arm 1: placebo infusions every 6 months; Arm 2: OCR infusions at Months 18 and 24 and then after Month 24 switch to placebo infusions every 6 months; Arm 3: OCR infusions every 6 months. The treatment period will be for a total of 48 months.

Full Description

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 and Month 12. At Month 12, participants will be randomized (1:1:1) to one of three Arms with randomized treatment beginning at Month 18: Arm 1: placebo infusions every 6 months; Arm 2: OCR infusions at Months 18 and 24 and then after Month 24 switch to placebo infusions every 6 months; Arm 3: OCR infusions every 6 months. The treatment period will be for a total of 48 months.

The study will consist of the following periods, with participants undergoing study assessments, including physical exams, neurological exams, EDSS, LCLA, SDMT, MFIS, MSQOL-54, PHQ9, EQ-5D-5L, and frequent co-registered research-quality MRI to sensitively assess for new inflammatory disease activity (new or enlarging T2 lesions), under schedules described in detail below. Biological sampling includes blood samples for functional immune profiling and stool samples for microbiome studies. Biomarker-based assessments are to include but not be limited to NfL and B cell levels.

Screening Period:

After obtaining informed consent, all screening assessments, and procedures to establish eligibility will be performed. These may be completed during one or more study visits within the 30-day screening window. Biological sampling will include 2 samples obtained prior to initiation of OCR treatment.

Open-label Treatment Period:

Participants that meet all eligibility criteria for enrollment will be initiated on OCR using the standard approved administration and will be followed for 12 months under the standard of care clinical efficacy and safety monitoring described below. Biological sampling occurs at 6 months and then at 12 months, with 2 samples to be taken prior to randomization (14 days +/- 7 days of randomization and on the day of randomization). Participants who discontinue study therapy during the open-label treatment period are asked to return for the scheduled study visits at Month 6 and Month 12 only, if these have not already occurred.

Blinded Treatment Period:

At Month 12, participants will be randomized (1:1:1) to either: (Arm 1) placebo infusions every 6 months; (Arm 2) continue OCR for another 12 months and then switch to placebo infusions; or (Arm 3) continue with OCR infusions every 6 months. The blinded treatment period will extend to Month 48 or until new disease activity is observed. All participants in the blinded treatment period will be closely monitored clinically and with frequent research 3Tesla (3T) MRIs using a standard protocol that assesses for the development of any new inflammatory disease activity observed following randomization. The development of such new inflammatory disease activity will represent the primary study endpoint. It will be defined as any one or more of the following: (1) one or more new clinical relapse(s) (see relapse definition) or (2) MRI evidence on frequent (every 3 months) serial scans of new disease activity. The central imaging analysis will identify incident new or enlarging MRI T2 lesions as compared to prevalent brain lesions documented in each participant from time of randomization (Month 12) and thereafter.

Frequent biological sampling will include blood samples collected every 3 months and stool samples collected every 6 months through the 48-month end of study.

Unblinded Follow-up period:

For participants who discontinue study therapy before Month 48, including those meeting the primary endpoint by manifesting new disease activity following randomization as defined above, blinded treatment allocation will be revealed and discussed, as described in section 3.5.1. Participants may receive OCR or other treatment and are to continue with study assessments per the schedule of events.

Functional immune response profiles of reconstituting B cells as well as non-B cells (T cells and myeloid cells) will be compared between participants who do, versus those do not, benefit from durable remission of relapsing biology, to identify cellular immune response profiles that may underlie the state of durable tolerance versus lack of durable tolerance.

Safety Follow-up:

Participants who are treated with OCR through Month 48 will have a phone visit 6 months after their last dose. If there are safety concerns, the participant can be brought in for an unscheduled visit.

Eligibility Criteria

Inclusion Criteria:

Have at least one clinical episode that satisfies McDonald 2017 criteria for early Multiple sclerosis (MS) for up to 2 years post-event 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 ≤ 2 years

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
