Trial Outcomes & Findings for Rebif® Rebidose® Versus Rebiject II® Ease-of-Use (NCT NCT02019550)

NCT ID: NCT02019550

Last Updated: 2017-03-07

Results Overview

The UTQ is a tool used to assess the ease-of-use of a device by the subject. Subjects were asked to assess their overall experience with using the device as "very difficult", "difficult", "neither easy nor difficult", "easy", or "very easy". Percentage of subjects who rated the overall use of device as "easy" or "very easy" were reported. Here results are presented by device sequence.

SECONDARY outcome

Timeframe: Weeks 4 and 8

Population: FAS included all relapsing remitting multiple sclerosis subjects who received at least 1 injection of Rebif using either Rebif Rebidose or Rebiject II and had at least 1 post-baseline evaluation/assessment. Here "Number of Participants Analyzed" signifies subjects evaluable for this outcome. Here results are presented by device sequence.

The UTQ is a tool used to assess the ease-of-use of a device by the subject. Subjects were asked to assess how convenient it was to store the injection device. Subjects responded as "Strongly disagree", "Disagree", "Neither agree nor disagree", "Agree", "Strongly agree" that the device was convenient to store.

Timeframe: Baseline, up to Week 8

Population: FAS included all relapsing remitting multiple sclerosis subjects who received at least 1 injection of Rebif using either Rebif Rebidose or Rebiject II and had at least 1 post-baseline evaluation/assessment. Here "Number of Participants Analyzed" = subjects evaluable for this outcome, "Number Analyzed" = subjects evaluable for specified dimensions.

The MusiQoL is a validated 31-item questionnaire describing 9 dimensions named according to its constitutive items:activities of daily living (8 items);psychological well-being (4 items);symptoms (3 items);friends relationships (4 items);family relationships (3 items);satisfaction with health care (RHCS 3 items);sentimental and sexual life (2 items);coping (2 items);and rejection (2 items). Each of the questions was answered using a 6-point Likert scale, defined as 1-Never/Not at all, 2-Rarely/A little, 3-Sometimes/Somewhat, 4-Often/A lot, 5-Always/Very much and 6-Not applicable. The scores of each dimension were obtained by computing mean of the item scores of dimension with negatively worded item scores reversed so that higher scores indicated higher health-related QoL. All 9 dimension scores were linearly transformed to a 0-100 scale,where higher score=higher health-related QoL. Global index score was computed as mean of the 9 dimension scores (range 0-100;higher score=higher QoL).
