Inclusion criteria
Inclusion criteria: Patients eligible for inclusion in this study have to fulfill all of the following criteria: 1. Written informed consent must be obtained before any assessment is performed. 2. Male and female patients aged 18-55 years. 3. Lifetime tetanus vaccination. 4. Patients with relapsing forms of MS, defined by 2005 revised McDonald criteria. 5. Patients with Expanded Disability Status Scale (EDSS) score of 0-6.5. 6. Agree to receive 2010/11 northern hemisphere seasonal influenza vaccine 7. Agree to receive tetanus toxoid booster vaccine Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Patients fulfilling any of the following criteria are not eligible for inclusion into the study: 1. Patients with a manifestation of MS other than relapsing MS. 2. History of vaccination with 2010/11 northern hemisphere seasonal influenza vaccine or plans to receive outside this study. 3. Laboratory-confirmed influenza disease within 6 months prior to Visit 1. 4. History of vaccination with H1N1 (2009 pandemic swine flu) vaccine or documented confirmed or suspected H1N1 influenza disease within 3 months prior to Day 1. 5. History of tetanus booster vaccination in one year prior to randomization. 6. History of anaphylaxis or serious reaction after administration of any vaccine, or hypersensitivity to eggs, egg protein, chicken feathers, influenza viral protein, neomycin, kanamycin, or any other vaccine component, chemically related substance, or component of the potential packaging materials. 7. Patients who have had an allergic reaction to previous tetanus vaccine 8. Patients with a history of chronic disease of the immune system other than MS or with a known immunodeficiency syndrome. 9. History or presence of malignancy (except for successfully treated basal or squamous cell carcinoma of skin). 10. A known or ‘new’ diagnosis of diabetes mellitus (if screening blood glucose is suspicious for diabetes [=126 mg/dL or =7 mmol/L if fasting; =200 mg/dL or 11.1 mmol/L if random testing] a patient should be further evaluated for diabetes mellitus). For a detailed descrition of all exclusion criteria, please refer to section 4.2 of the enclosed protocol.

|---|---|
| Main Objective: To evaluate the immune response in MS patients treated with fingolimod (compared to placebo) three weeks after a single dose of seasonal influenza vaccine as assessed by the proportion of patients showing seroconversion or showing a significant increase in the HAI antibody titers against at least one of three virus strain antigens after vaccination.;Secondary Objective: • To evaluate the immune response in MS patients treated with fingolimod (compared to placebo) six weeks after a single dose of seasonal influenza vaccine as assessed by the proportion of patients showing seroconversion or showing a significant increase in the HAI antibody titers against at least one of three virus strain antigens after vaccination. • To evaluate the immune response to a single dose of tetanus toxoid (TT) as assessed by the proportion of patients with seroconversion or a significant increase (=4-fold) in antibody titers. • To estimate the inhibition of an immune response to each strain included in the seasonal influenza vaccine as assessed by the relative difference of the geometric mean antibody titer ratio on fingolimod as compared to placebo three and six weeks after a single dose of seasonal influenza vaccine. For a detailed description of the Secondary Objectives, please refer to section 2.2 of the enclosed protocol.;Primary end point(s): The primary variable is the responder rate to the seasonal influenza vaccine at Visit 7. The responder rate is defined as the proportion of patients fulfilling one of the following criteria for at least one of the three strains contained in the seasonal influenza vaccine: • Seroconversion: the pre-vaccination antibody titer measurement (Visit 6) is <1:10 and the post-vaccination measurement is =1:40. • Significant increase: the pre-vaccination antibody titer measurement (Visit 6) is =1:10 and the increase in antibody titer from this to the post-vaccination measurement is =4-fold. | — |
