Primary Outcome Measures:
  • Responder Status Based on Patient Global Impression of Change (PGIC) Score at Visit 5 (Week 13) [ Time Frame: Assessed at Visit 4 (Week 9) and Visit 5 (Week 13) or early termination. Presented results generated via LOCF approach. ] [ Designated as safety issue: No ]
    The PGIC is a patient-reported measure of improvement in pain sensation and quality of life scored on a scale from 1 (very much improved) to 7 (very much worse). To meet the criteria for a responder in this study, patients must report a score of 1 (very much improved) or 2 (much improved) on the PGIC.


Secondary Outcome Measures:
  • Change From Baseline to Visit 5 (Week 13) in the Visual Analog Scale (VAS) 1-week Pain Recall Score [ Time Frame: Change from Baseline (Week 3) to Visit 5 (Week 13) ] [ Designated as safety issue: No ]
    The VAS assessment ranges from a scale of 0 (no pain) to 100 (worst possible pain).

Arms Assigned Interventions
Placebo Comparator: Placebo
Placebo tablets, twice a day, oral administration
Drug: Placebo
  • Placebo tablets, oral administration, twice daily for 10 weeks during randomized, double-blind treatment period. Duloxetine capsules, oral administration, 30 mg/day for 1 week after randomization to effect a duloxetine down-taper.

Experimental: Milnacipran
Milnacipran tablets, 100 to 200 mg/day, oral administration, twice daily in divided doses.
Drug: Milnacipran
  • Milnacipran tablets, 100 to 200 mg/day, oral administration, twice daily in divided doses for 10 weeks during randomized, double-blind treatment period. Placebo capsules, 1 capsule/day administered for 1 week after randomization to maintain double-blind duloxetine down-taper.
  • Milnacipran tablets, 100 to 0 mg/day, oral administration, twice daily in divided doses for 1 week during double-blind down-taper treatment period.
Other Name: Savella

Detailed Description:
  • Two weeks Duloxetine 60 mg Open-Label Period
  • Randomization to Double-Blind Treatment Period: 10 weeks Milnacipran (direct switch) or 10 weeks placebo (one week blinded 30 mg duloxetine)
  • One week Double-Blind Down-Taper Period
