Primary Outcome Measures :
  1. The primary objective in the acute phase of this study is to compare the incidence of treatment-emergent nausea
  2. for patients initially dosed at duloxetine 30 mg QD
  3. (once-daily), versus duloxetine 60 mg QD.
  4. The primary objective in the extension phase of this study is to compare efficacy in patients not meeting response criteria during the acute phase for patients dosed at duloxetine 60 mg QD versus duloxetine 120 mg QD.

Secondary Outcome Measures :
  1. The secondary objective of greatest importance is to compare the incidence of treatment-emergent nausea
  2. (as defined for the primary objective) for patients
  3. initially dosed at duloxetine 30 mg QD, versus duloxetine 30 mg BID (twice-daily).
  4. Additional secondary objectives include comparing the three initial dosing groups in regards to:Mean changes from baseline in the category total scores and individual items scores of the AMDP-5
  5. The incidence and severity of adverse events using rates of spontaneously reported treatment-emergent adverse events, rates of discontinuations due to
  6. adverse events, categorical changes in AMDP-5 items, mean changes and categorical changes in vital signs
  7. as well as mean changes and rates of abnormal laboratory analytes
  8. Mean changes from baseline in the HAMD17 total score, HAMD subscales, HAMD17 individual items, 30-item Inventory of Depressive Symptoms,
  9. Clinician Rated (IDS-30) total score and individual items, Brief Pain Inventory items and interference
  10. total score, Visual Analog Scales for pain, Clinical Global Impressions of Severity (CGI-Severity), Post-baseline means
  11. on the Patient's Global Impression of Improvement (PGI-I), Remission rates (HAMD17 total score of less than 7),
  12. and response rates (greater than 50% decrease from baseline on the HAMD17 total score).
  13. - Sexual dysfunction, as measured by categorical changes (same, better, worse) and presence vs. absence, based on the patient global assessment of sexual functioning.
  14. Time to onset of action in depression (30% improvement in Maier Subscale of HAMD) and painful physical symptoms (30% improvement in as measure by the BPI interference total score).
