| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
General Aim: To assess the efficacy and safety of BGC20-0134 in patients with RRMS treated for 24 weeks in in the double-blind period and for a further 24 weeks in the open-label period 
 Primary Endpoint: Cumulative number of new gadolinium-enhanced (GdE) T1 weighted lesions developing while on treatment (specifically the sum of new GdE T1 lesions seen on MRI at weeks 12, 16, 20 and 24) 
 | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
• MRI endpoints:    Cumulative number of total GdE T1 weighted lesions    Cumulative number of new T2 weighted lesions    Patients free of GdE (T1-weighted) lesions    Change in volume of GdE T1 weighted, and new T2-weighted lesions    Brain atrophy    Cumulative number of new T1 hypointense lesions (black holes) • Number of clinical relapses from baseline • Appearance of a new symptom or worsening of an old symptom, attributable to MS  • Change on the Expanded Disability Status Scale (EDSS) • Number of patients receiving methylprednisolone treatment for a relapse • Serum levels of cytokines during the first 24 weeks  • Quality of life (MSQOL-54) assessment • PK for determination of circulating levels of BGC20-0134 and plasma concentrations of dihomo-gamma linolenic acid (DHGLA) during the first 24 weeks. • Safety assessment During the open label period only the clinical endpoints are assessed. |

| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
| Patients aged ≥18 with relapsing-remitting multiple sclerosis (EDSS score 0-5.5), with evidence of disease activity defined as at least one relapse or the presence of active MRI lesion/s consistent with MS during the year prior to inclusion | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
MS-related exclusion criteria: • MS relapse or systemic corticosteroids in the previous 1 month • Secondary progressive (SPMS), progressive relapsing (PRMS), or primary progressive MS (PPMS) • Treatment with other agents for MS within the previous 3 months (intertferon beta, glatiramer acetate, intravenous immunoglobulin or plasmapherese) or within the previous 12 months (other MS drugs) • Treatment with agents for the non-symptomatic treatment of MS within the previous 3 months 
 General exclusion criteria • Pregnant or breast feeding • Participation in a clinical study of an unlicensed drug in the previous 6 months • Has a clinically significant abnormal serum biochemistry, haematology or urine examination values within 14 days prior to the start of the study. • Has a 12-lead ECG with abnormal QTc interval within 14 days prior to the start of the study. • Presence of pacemakers or foreign metal objects in the body which would contraindicate an MRI scan, or renal impairment which would contraindicate gadolinium injection • Has any systemic disease, which can influence his/her safety and compliance, or the evaluation of disability. • Any finding on medical history or physical examination which would prevent the patient being able to fully comply with the requirements of the study. • Any finding on medical history or physical examination which would affect absorption of the study drug; e.g. metabolic disorders. • Serious concomitant medical conditions: e.g. HIV infection, Hepatitis B or C, uncontrolled diabetes, malignancy. • Current history of cancer, excluding localised non-melanoma skin cancer  • Known allergies to the study drug, its constituents or gadolinium (MRI contrast). • Has suffered from major depression or any other psychiatric disorder • Incapability of giving informed legal consent • Co-worker, student, relative or spouse of the investigator • Patients unable to swallow oral medications  • Previous participation in this study |
