Primary Outcome Measures:
  • Proportion of Subjects in the Main Subset With no Failures Occurring in Any Step During the Subject's Use of the Avonex Single-Use Autoinjector. [ Time Frame: Outcome was assessed at Day 22 ] [ Designated as safety issue: Yes ]
    Primary outcome measure was from data captured in the Observation Form that was to be completed by the Trainer/Observer who documented the patient's ability to self-inject with the Avonex single-use autoinjector. Steps and/or actions in the Observation Form were pre-defined as optimal, non-optimal, or failure. Failure was defined as completing the step/action incorrectly, improperly, or in a non-optimal manner that resulted in adverse outcome, resulting in the subject sustaining an injury or the device becoming unusable/nonfunctional for injection, or a possible device malfunction.

Secondary Outcome Measures:
  • Mean Score for Ease of Use Grading Scale. [ Time Frame: Day 8, Day 15, Day 22 ] [ Designated as safety issue: No ]
    Subjects scored the ease of use of the Avonex single-use autoinjector using a scale that ranged from 0 (extremely difficult) to 10 (extremely easy).

  • Proportion of Subjects Who Rated the Avonex Single-use Autoinjector Printed Training Materials as Very Effective. [ Time Frame: Day 8, Day 15, Day 22 ] [ Designated as safety issue: No ]
    Subjects evaluated how effective the printed instructions were in educating how to use the Avonex single-use autoinjector. Subjects could choose one the the following possible answers: Not effective at all, somewhat effective, neutral, somewhat effective, and very effective.

  • Proportion of Subjects Who Indicated no Difficulty With the Injection Procedure of the Avonex Single-use Autoinjector. [ Time Frame: Day 8, Day 15, Day 22 ] [ Designated as safety issue: Yes ]
    Subjects evaluted if they had experienced any diffculty with the procedure in preparing, injecting, removing, and disposing process after each injection with the Avonex single-use autoinjector. Subjects answered yes or no to the following question: Did you have any difficulty with your injection?

  • Proportion of Subjects in the Main Subset Who Indicated a Preference for the Avonex Single-use Autoinjector Over the Manual Avonex Prefilled Syringe. [ Time Frame: Day 23 ] [ Designated as safety issue: No ]
    Subjects could answer yes or no to whether they preferred using the Avonex single-use autoinjector over the manual Avonex Prefilled Syringe. Preference was defined as subjects answering yes to the following question: Do you prefer this single-use autoinjector over the manual injection?

  • Mean Pain Score After Injection With the Avonex Single-use Autoinjector. [ Time Frame: Day 8, Day 15, Day 22 ] [ Designated as safety issue: Yes ]
    Subjects scored the pain after the use of the Avonex single-use autoinjector on a scale ranging from 0 to 10. Score of 0 was no pain and a score of 10 was extremely painful.

  • Proportion of Subjects Having no Erythema, Induration, or Tenderness, and Normal Temperature at the Injection Site After Injection With the Avonex Single-use Autoinjector. [ Time Frame: Day 8 to Day 22 ] [ Designated as safety issue: Yes ]
    The clinician/Investigator evaluated the injection site for erythema, induration, and tenderness as none, mild, moderate, or severe after the use of the Avonex single-use autoinjector. Temperature at the injection site was evaluated as normal, warm, or hot.
