Official title: Flexible Dosed Duloxetine Versus Placebo in the Treatment of Fibromyalgia

The purpose of this study is to confirm the efficacy and safety of duloxetine 60-120 mg once daily in comparison to placebo on symptom improvement in patients meeting criteria for fibromyalgia aged 18 and older. Patients will be randomized to duloxetine or placebo, however, all patients will receive duloxetine at some point in the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient's Global Impressions of Improvement (PGI-I) at Week 12

    The PGI-Improvement scale is a patient-rated instrument that measures perceived improvement in symptoms. It is a 7-point scale where a score of 1 indicates that the patient is "very much improved," a score of 4 indicates that the patient has experienced "no change," and a score of 7 indicates that the patient is "very much worse."

    Measured: 12 weeks

Secondary outcomes (14)
  1. Change From Baseline in Brief Pain Inventory (BPI) (Modified Short Form) at 12 Week Endpoint

    BPI is a self-reported form that assesses severity of pain and the interference of pain on function. There are 4 questions assessing the severity for worst pain, least pain, and average pain in the past 24 hours, and the pain right now. Severity scores range from 0 (no pain) to 10 (pain as bad as you can imagine). There are 7 questions assessing the interference of pain in the past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Interference scores range from 0 (does not interfere) to 10 (completely interferes).

    Measured: Baseline, 12 weeks

  2. Change From Baseline in Multidimensional Fatigue Inventory (MFI) at 12 Week Endpoint

    MFI is a 20-item, self-reporting instrument designed to collect data on the following 5 dimensions: general fatigue, physical fatigue, mental fatigue, reduced motivation, and reduced activity. Each dimension score is derived by summing the scores of the 4 individual items that pertain to each dimension. Item scores range from 1 to 5; thus, dimensional scores range from 4 to 20 with a higher score reflecting greater levels of fatigue.

    Measured: Baseline, 12 weeks

  3. Change From Baseline in Beck Depression Inventory-II (BDI-II) at 12 Week Endpoint

    BDI-II is a 21-item patient-completed questionnaire designed to assess characteristics of depression. Each item is rated on a 4-point scale (0 = not present; 3 = present in the extreme). This questionnaire will be used to rate the severity of depressive symptoms and any improvement during the course of the trial. The total score ranges from 0 to 63; the higher the score, the more severe the depressive symptoms.

    Measured: Baseline, 12 weeks

  4. Change From Baseline in Clinical Global Impressions of Severity (CGI-S) at 12 Week Endpoint

    The Clinical Global Impressions of Severity (CGI-Severity) scale evaluates the severity of illness at the time of assessment. The score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).

    Measured: Baseline, 12 Weeks

  5. Change From Baseline in Beck Anxiety Inventory (BAI) at 12 Week Endpoint

    BAI is a 21-item patient-completed questionnaire designed to assess characteristics of anxiety. Each item is rated on a 4-point scale (0 = not present; 3 = present in the extreme). This questionnaire will be used to rate the severity of anxiety symptoms and any improvement during the course of the trial. The total score ranges from 0 to 63; the higher the score, the more severe the anxiety symptoms.

    Measured: Baseline, 12 weeks

  6. Change From Baseline in 36-Item Short-form Health Survey (SF-36) at 12 Weeks

    The patient-rated SF-36 consists of 36 questions covering eight health domains: physical functioning, bodily pain, role limitations due to physical problems, role limitations due to emotional problems, general health perceptions, mental health, social function, and vitality. Each domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale, with higher scores indicating better health status or functioning. Two summary scores: the Physical Component Summary and the Mental Component Summary are constructed based on the eight SF-36 domains.

    Measured: Baseline, 12 weeks

  7. Change From Baseline in Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (MGH-CPFQ) Total Score at 12 Week Endpoint

    The MGH-CPFQ is a self-report instrument consisting of seven questions pertaining to an individual's cognitive and physical well-being. Each question is rated 1 = "greater than normal" to 6 = "totally absent". Total score ranges from 7 to 42.

    Measured: Baseline, 12 weeks

  8. Change From Baseline in the Mood, Anxiety, Pain, Sleep, and Stiffness Likert Scale at 12 Week Endpoint

    Likert scales are patient-rated assessments. Mood: feeling low, sad or depressed; rated 0 = not feeling low, sad or depressed to 10 = feeling extremely low, sad or depressed. Anxious: anxious feelings; rated 0 = not feeling anxious to 10 = extremely anxious. Sleep: how much patient bothered by sleep difficulties; rated 0 = not bothered to 10 = extremely bothered. Pain: how much patient bothered by painful physical discomforts; rated 0 = not bothered to 10 = extremely bothered. Stiffness: how stiff patient felt in past 24 hours; rated 0 = not felt any stiffness to 10 = felt extremely stiff.

    Measured: Baseline, 12 weeks

  9. Number of Responders: 30% Improvement in Brief Pain Inventory Average Pain at 12 Week Endpoint

    Response was defined as at least 30% reduction from baseline to endpoint (last observation carried forward) for BPI average pain score. BPI average pain score assesses the severity of the average pain in the past 24 hours. The average severity score ranges from 0 (no pain) to 10 (pain as bad as you can imagine).

    Measured: 12 Weeks

  10. Number of Responders: 50% Improvement in Brief Pain Inventory Average Pain Score at 12 Week Endpoint

    Response was defined as at least 50% reduction from baseline to endpoint (last observation carried forward) for BPI average pain score. BPI average pain score assesses the severity of the average pain in the past 24 hours. The average severity score ranges from 0 (no pain) to 10 (pain as bad as you can imagine).

    Measured: 12 weeks

  11. Change From Baseline in Blood Pressure at 12 Week Endpoint

    Measured: Baseline, 12 weeks

  12. Change From Baseline in Heart Rate at 12 Week Endpoint

    Measured: Baseline, 12 weeks

  13. Number of Patients With Columbia Suicide Severity Rating Scale (CSSR-S) Events (Behaviors, Ideations, Acts)

    C-SSRS: scale capturing occurrence, severity, and frequency of suicide-related thoughts and behaviors. Number of patients with suicidal behaviors, ideations, and acts are provided. Suicidal behavior: a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide. Suicidal ideation: a "yes" answer to any one of 5 suicidal ideation questions, which includes wish to be dead, and 4 different categories of active suicidal ideation. Suicidal act: a "yes" answer to actual attempt or completed suicide.

    Measured: Baseline through 12 Weeks

  14. Change From Baseline in Weight at 12 Week Endpoint

    Measured: Baseline, 12 weeks
