What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Adverse Drug Reaction
Time Frame: From Week 1 to 52 weeks at maximum
An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Relatedness to LYRICA Capsules was assessed by the physician.
From Week 1 to 52 weeks at maximum

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

From Week 1 to 52 weeks
Change From Baseline in Pain Score at Week 52
Time Frame: Baseline and at Week 52
The pain from fibromyalgia experienced during the past 24 hours was rated by participants at the time of getting up in the morning on an 11-grade scale, ranging from 0 (no pain) to 10 (the most severe pain possible). Mean change from baseline in the pain score at Week 52 was presented along with standard deviation.
Baseline and at Week 52
Change From Baseline in Quality of Sleep Score at Week 52
Time Frame: Baseline and at Week 52
The quality of sleep experienced during the past 24 hours was rated by participants at the time of getting up in the morning on an 11-grade scale, ranging from 0 (the best sleep possible) to 10 (the worst sleep possible). Mean change from baseline in quality of sleep score at Week 52 was presented along with standard deviation.
Baseline and at Week 52
Patient's Impression (PGIC) at Week 52
Time Frame: At Week 52
The patient's impression (patient global impression of change [PGIC]) at Week 52, as compared to the baseline condition (including the first day of treatment), was rated by participants on a 7-grade scale.
At Week 52
Physician's Impression (CGIC) at Week 52
Time Frame: At Week 52
The physician's impression (clinical global impression of change [CGIC]) at Week 52, as compared to the baseline condition (including the first day of treatment), was rated by the physician on a 7-grade scale.
At Week 52
Change From Baseline in Patient Health Questionnaire (PHQ-9) Score at Week 52
Time Frame: Baseline and at Week 52
The problems associated with depression-related symptoms experienced during the last 2 weeks were rated by participants ranging from 0 (not at all) to 3 (nearly every day) in total 0 to 27(the higher the more severe) consisting the following 9 items: 1) little interest or pleasure in doing things; 2) depressed, or hopeless; 3) trouble falling or staying asleep, or sleeping too much; 4) feeling tired or having little energy; 5) poor appetite or overeating; 6) feeling bad about yourself - or that you are a failure or have let yourself or your family down; 7) trouble concentrating on things, such as reading the newspaper or watching television; 8) moving or speaking so slowly that other people could have noticed. Or the opposite - being so fidgety or restless that you have been moving around a lot more than usual; and 9) thoughts that you would be better off dead, or of hurting yourself. Mean change from baseline in the evaluation score was presented along with standard deviation.
Baseline and at Week 52
Change From Baseline in Health Status of EuroQol 5 Dimension (EQ-5D) at 52 Weeks
Time Frame: Baseline and at Week 52
Health status (EQ-5D) was evaluated based on the following 5 dimensions: mobility, self-care, usual activity (e.g., work, study, housework, family, or leisure activities), pain/discomfort, and anxiety/depression. Each dimension was rated in the three levels of response alternatives "no problems," "some problems," or "extreme problems." For the analysis of EQ-5D, the response outcome for the five dimensions was converted to a utility value using tariff value set based on the Japanese version of EQ-5D. The utility value was not assigned if there was no response in any one of the five dimensions. 1 for full health and 0 for being dead: a positive (negative) number implies that the health state is better (worse) than dead. Mean change from baseline in the evaluation score was presented along with standard deviation.
Baseline and at Week 52
Change From Baseline in Fibromyalgia Activity Score (FAS-31) at 52 Weeks
Time Frame: At Week 52
FAS-31 (ranged from 0 to 31) is calculated as the combined score of the widespread pain index (WPI, ranged from 0 to 19) and the symptom severity (SS) scale (ranged from 0 to 12). The WPI is a measure of the number of painful body regions. The SS is the scale of the severity in the three symptoms (fatigue, waking unrefreshed, and cognitive symptoms; ranged from 0 to 3 each) and general physical symptoms (ranged from 0 to 3). WPI ranged from 0 to 19 the higher score indicates more severe of activity, SS ranged from 0-12 also higher score shows more severe symptoms observed. Mean change from baseline in the evaluation score was presented along with standard deviation.
At Week 52
Change From Baseline in the Japanese Version of the Revised Fibromyalgia Impact Questionnaire (JFIQR) at 52 Weeks
Time Frame: At Week 52
JFIQR is a Japanese version of the Revised Fibromyalgia Impact Questionnaire (FIQR), which was established for overall evaluation of the influence of fibromyalgia on patient's health. It consists of three linked sets of domains: "function (9 questions)," "overall impact (2 questions)," and "symptoms (10 questions)." Participants responded to the questions based on an 11-grade scale, ranging from 0 to 10, with 10 being the worst. For the analysis of JFIQR, the score for each domain was modified as follows: The summed score for "function" (ranged from 0 to 90) was divided by 3 and the summed score for "symptoms" (ranged from 0 to 100) was divided by 2. The summed score for "overall impact" (ranged from 0 to 20) was not modified. The total score, the sum of the three modified domain scores (ranged from 0 to 100, the lower score represents a better outcome), was used for the analysis. Mean change from baseline in the evaluation score was presented along with standard deviation.
