E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the efficacy and dose-response of M2951 on the number of gadolinium-positive (Gd+) T1 MRI lesions versus placebo after 24 weeks of treatment.
The primary objective of the open-label extension period is to evaluate the long-term safety, efficacy, and HRQoL of M2951 for an additional 2 years, at a initial dose of 75 mg once daily which is eventually switched to 75 mg twice daily. |
|
E.2.2 | Secondary objectives of the trial |
The key secondary objectives are as follows: - To evaluate the efficacy and dose-response of M2951 on clinical endpoints over 24 weeks versus placebo - To evaluate the safety of M2951
Additional secondary objectives are as follows: - To evaluate the efficacy of M2951 on additional MRI parameters over 24 weeks versus placebo - To evaluate the efficacy of M2951 on clinical and MRI endpoints from Week 24 to 48 - To evaluate the efficacy of Tecfidera on clinical and MRI endpoints over 24 weeks - To evaluate the efficacy of Tecfidera on clinical and MRI endpoints from Week 24 to 48 - To evaluate the safety of Tecfidera |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacodynamics Bruton’s tyrosine kinase (BTK) occupancy (version and date as per current protocol).
Bruton’s tyrosine kinase (BTK) occupancy samples will be taken from a subset of approximately 30 evaluable subjects treated with M2951 or placebo from selected sites capable of providing samples.
Objective: To determine the Change from Baseline in percent BTK occupancy to predose on Days 28, 84 and 168 and 2 hours postdose on Days 1, 28, 84 and 168. |

E.3 | Principal inclusion criteria |
1. Participants with a diagnosis of RMS (may include participants with SPMS with superimposed relapses provided they meet the other criteria) in accordance with revised McDonald criteria for MS and Lublin and Reingold 2. Male or female aged 18 to 65 years 3. One or more documented relapses within the 2 years before Screening with either: a) One relapse which occurred within the last year prior to randomization or b) the presence of at least 1 Gd+ T1 lesion within 6 months prior to randomization would make the patient eligible. 4. EDSS score of 0 to 6 at Baseline 5. Women of childbearing potential must use a supplementary barrier method together with a highly effective method of contraception for 4 weeks prior to randomization, throughout the trial, and for 90 days after the last dose of IMP. Male subjects and their female partners must also use the above. 6. Signed and dated informed consent (participants must be able to understand the informed consent) indicating that the participant has been informed of all the pertinent aspects of the trial prior to enrolment and will comply with the requirements of the protocol.
For the open-label extension period: Participants who have withdrawn after randomization (eg, due to AEs or lack of efficacy) will not be replaced and will not be eligible to participate in a OLE Period. Only subjects who have completed the 48 - week main study are eligible to participate. |

Vaginal candidiasis, onychomycosis, and genital or oral herpes simplex virus considered by the Investigator to be sufficiently controlled would not be exclusionary. • History of or positive testing for HIV, HCV antibody and/or polymerase chain reaction, HBsAg (+) and/or hepatitis B core total, and/or IgM antibody (+) at Screening. • The subject: • Has a history of or current diagnosis of active tuberculosis (TB) or • Is currently undergoing treatment for latent TB infection (LTBI) or • Has an untreated LTBI or • Has a positive QuantiFERON®-TB test at Screening. • Indeterminate QuantiFERON • Participants with current household contacts with active TB will also be excluded • History of splenectomy or any major surgery within 2 months prior to Screening • History of myocardial infarction or cerebrovascular event as per the protocol • History of attempted suicide within 6 months prior to Screening or a positive response to items 4 or 5 of Columbia-Suicide Severity Rating Scale (C-SSRS) • An episode of major depression within the last 6 months prior to Screening • On anticoagulation, fish oil supplements, or antiplatelet therapy other than daily aspirin for cardioprotection and treatment of Tecfidera induced flushing • History of cancer, except adequately treated basal cell or squamous cell carcinoma of the skin • Breastfeeding/lactating or pregnant women • Participation in any investigational drug trial within 1 month or 5 half-lives of the investigational drug, whichever is longest, prior to Screening • Participants currently receiving (or unable to stop using prior to receiving the first dose of IMP) medications or herbal supplements known to be potent inhibitors of CYP3A • History of or current alcohol or substance abuse • Clinically significant abnormality on electrocardiogram or screening chest X-ray • Clinically significant laboratory abnormality
