Multiple Sclerosis
Conditions
Brief summary
The purpose of this trial is to test the Single-Use Autoinjector for a) ease of use; b) multiple domains related to subject's acceptability and satisfaction, and c) reliability of the correct function for self-injection of Rebif® 44 mcg sc tiw in subjects with relapsing multiple sclerosis (RMS).
Interventions
The device is a ready to use single use auto injector containing Rebif® 44 mcg in a 0.5 mL prefilled syringe for sc injection

Exclusion criteria
1. Have used any other injectable medications (i.e. for pain) on a regular basis during the week prior to Screening or throughout the duration of the trial (the administration of a single injection for treatment or prophylaxis of a condition unrelated to MS or Rebif® therapy (e.g., influenza or pneumococcus vaccination) will be acceptable) 2. Have received MS therapy other than Rebif® within twelve weeks prior to Screening or at any time during the trial (e.g., other disease modifying drugs, Rebif® New Formulation, combination therapy, immunomodulatory and/or immunosuppressive agents, including but not limited to any interferon, glatiramer acetate (Copolymer I), cyclophosphamide, cyclosporine, methotrexate, linomide, azathioprine, mitoxantrone, teriflunomide, laquinimod, cladribine, total lymphoid irradiation, anti-lymphocyte monoclonal antibody treatment (e.g. natalizumab, alemtuzumab/Campath, anti- CD4), Intravenous immunoglobulin (IVIg), cytokines or anti-cytokine therapy) and telbivudine 3. Have inadequate liver function, defined by a alanine aminotransferase (ALT) \> 2.5x upper limit of normal (ULN), or alkaline phosphatase \> 2.5x ULN, or total bilirubin \> 2.5x ULN 4. Have inadequate bone marrow reserve, defined as a total white blood cell count \< 3.0x 109/L, platelet count \< 75x109/L, haemoglobin \< 100g/L 5. Have complete transverse myelitis or bilateral optic neuritis 6. Have a history of alcohol or drug abuse 7. Have thyroid dysfunction 8. Have moderate to severe renal impairment 9. Have a major medical or psychiatric illness that in the opinion of the investigator creates undue risk to the subject or could affect compliance with the study protocol 10. Have a history of seizures not adequately controlled by treatment 11. Have serious or acute cardiac disease, such as uncontrolled dysrhythmias, uncontrolled angina pectoris, cardiomyopathy, or uncontrolled congestive heart failure 12. Have, in the opinion of the investigator, any visual, physical or cognitive impairment that would preclude the subject from self-injecting with the single-use autoinjector 13. Have a known hypersensitivity or allergy to interferon-beta or any of the excipients 14. Have participated in another clinical trial within the past thirty days 15. Are pregnant or attempting to conceive

Recruitment details
109 subjects were recruited from 12 US clinics in the US during the trial period Oct 2009 to April 2010.
Pre-assignment details
Subjects who signed informed consent and satisfied the eligibility critera at screening returned to the clinic on study day 1 to begin treatment. All subjects participating in the trial received Rebif 44 mcg subcutaneious (sc, three times per week (tiw) using the single-use autoinjector (SA).

Outcome results
Proportion of Relapsing Multiple Sclerosis (RMS) Subjects Rating the Single-use Autoinjector as 'Easy to Use' or 'Very Easy to Use' for Self-injection in a User Trial Questionnaire
Data from the User Trial Questionnaire, Question 14 (Overall, how do you rate your experience with using the injection device?) Mean and confidence interval refer to proportion of subjects responding positively to question. Missing values were replaced with worst case response.
Time frame: at 12 weeks
Population: Subjects in the all enrolled analysis set who received at least one dose of investigational medicinal product (IMP) were included in the ITT analysis set. This analysis set was used to analyze the primary and secondary variables and all safety data.
