What researchers measure

Primary outcomes

  1. To assess efficacy of duloxetine 60 mg twice daily (BID) compared with placebo on reduction of pain severity, measured by average pain item of Brief Pain Inventory (BPI) in patients with ACR-defined primary fibromyalgia, with or without major depression.

Secondary outcomes

  1. To evaluate the efficacy of duloxetine 60 mg once daily (QD) compared with placebo during a 12-week, double-blind, acute therapy phase on the reduction of pain severity as measured by the average pain item of the Brief Pain Inventory (BPI).

  2. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of the area under the curve of pain relief as derived from BPI average pain score

  3. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of Fibromyalgia Impact Questionnaire (FIQ) total score

  4. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on improvement of Brief Pain Inventory (BPI) severity (worst pain, least pain, pain right now) and interference scores

  5. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of Tender point pain thresholds: mean thresholds and number of points with a low threshold

  6. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of Clinical Global Impression of Severity (CGI)

  7. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of Patient Global Impression of Improvement (PGI)

  8. To evaluate efficacy of duloxetine 60 mg QD and 60 mg BID vs. placebo during a 12-week, double-blind, acute therapy phase on the improvement of Hamilton Depression 17- item Rating Scale (HAMD17) total score

  9. To demonstrate that the effect of duloxetine 60 mg QD and duloxetine 60 mg BID on the BPI average pain score is independent of the presence or absence of a major depressive disorder (MDD) as defined by DSM-IV.

  10. To evaluate whether improvement in pain severity (assessed by BPI average pain score) is direct analgesic effect of duloxetine therapy and independent of treatment effect on mood improvement, as measured by total score of HAMD17
