Measured: Randomization (Week 8) to Week 14
Change in Functional Impairment From Randomization (Week 8) to End of Treatment (Week 16) as Measured by the Sheehan Disability Scale (SDS) Total Score
Sheehan Disability Scale (SDS) is 5-item, self-administered scale that measures the extent a patient is impaired by their disease. Higher scores indicate more severe impairment. The SDS total score is calculated as the sum of the score for the 3 inter-correlated domains (school/work, social life, and family life/home responsibilities) and ranges from 0 (unimpaired) to 30 (highly impaired).
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change in Functional Impairment From Randomization (Week 8) to End of Treatment (Week 16) as Measured by SDS Work/School Domain Score
A 5-item, self-administered scale that measures the extent a patient is impaired by their disease. Higher scores indicate more severe impairment. The 3 inter-correlated domains are school/work, social life, and family life/home responsibilities. The numerical rating for the work/school domain score is 0- 10, where 10 is considered to be 'highly impaired'.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change in Functional Impairment From Randomization (Week 8) to End of Treatment (Week 16) as Measured by SDS Social Life Domain Score
A 5-item, self-administered scale that measures the extent a patient is impaired by their disease. Higher scores indicate more severe impairment. The 3 inter-correlated domains are school/work, social life, and family life/home responsibilities. The numerical rating for the SDS social life domain score is 0- 10, where 10 is considered to be 'highly impaired'.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change in Functional Impairment From Randomization (Week 8) to End of Treatment (Week 16) as Measured by SDS Family Life/Home Responsibilities Domain Score
A 5-item, self-administered scale that measures the extent a patient is impaired by their disease. Higher scores indicate more severe impairment. The 3 inter-correlated domains are school/work, social life, and family life/home responsibilities. The numerical rating for the SDS family life/home responsibilities domain score is 0- 10, where 10 is considered to be 'highly impaired'.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change in Overall Quality of Life and Satisfaction From Randomization (Week 8) to End of Treatment (Week 16) by Assessing the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) % Maximum Total Score
The Q-LES-Q-SF (Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form)total score is derived by summing item scores 1 to 14. Higher scores are indicative of greater enjoyment or satisfaction in each domain. The Q-LES-Q-SF % maximum total score is calculated as 100% × (Q-LES-Q-SF total score - 14) / 56, and can range from 0% to 100%.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change From Randomization (Week 8) to End of Treatment (Week 16) in Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q LES-Q-SF) Item 15
The Q-LES-Q-SF (Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form) measures the patient's satisfaction with medication and overall quality of life. The 15th item queries respondents' satisfaction with the medication they are taking, rated on a 1 to 4 scale, score 0 indicates that no medication was taken. Higher scores are indicative of greater satisfaction.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change From Randomization (Week 8) to End of Treatment (Week 16) in Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q LES-Q-SF) Item 16
The Q-LES-Q-SF (Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form) measures the patient's satisfaction with medication and overall quality of life. The 16th item is a global rating of overall life satisfaction and contentment, rated on a 1 to 5 scale. Higher scores are indicative of greater satisfaction.
Measured: Randomization (Week 8) to end of treatment (Week 16)
Change in EuroQol - 5 Dimensions (EQ-5D) From Randomization (Week 8) to End of Treatment (Week 16)
A self-assessment questionnaire that provides 2 measures of health status. The EQ-5D index score is a weighted linear combination over 5 dimensions of health status. The score for each of the 5 dimensions can range from 1 to 3, and an equation is used to calculate the EQ-5D index score. The EQ-5D index score can range from possible negative values (minimum -0.415) to a maximum of 1.0. The EQ-VAS is a visual analog scale with a range of 0 to 100. For both variables, a higher score indicates a better health state.
Measured: Randomization (Week 8) to end of treatment (Week 16)
