Primary Outcome Measures:
  • Change from Baseline to Week 6 in daily average pain intensity measured by the 11 point Pain Intensity Numerical Rating Scale (NRS; 0-10). Baseline is the average daily Pain NRS score during Stabilization Phase prior to Randomization (3 days). [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Physical examination at Screening, Week 6 and Week 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Change from Baseline to Weeks 1, 2, 4, 8, 12 and 16 in the daily average pain intensity NRS score. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Change from Baseline to Weeks 1, 2, 4, 6, 8, 12 and 16 in the daily worst pain intensity NRS score. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Average number of doses of rescue medication required per week (up to Week 16). [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Clinical laboratory assessments (hematology, blood chemistry, PT/PTT, urinalysis) at Screening, Baseline, and Weeks 2, 4, 6, 12 and 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Change in Patient's Global Assessment of Disease (Cancer Pain) Activity at Weeks 1, 2, 4, 6, 8, 12 and 16. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Response as defined by a ≥30/50/70/90% reduction from Baseline in the daily average pain intensity NRS score. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Vital sign measurements at Screening, Baseline, and Weeks 2, 4, 6, 12, and 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Neurologic examination at Screening, Baseline, and Weeks 2, 4, 6, 12, and 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Weight measurements at Screening, Week 6 and Week 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Change from Baseline to Weeks 1, 2, 4, 6, 8, 12 and 16, in the BPI worst pain scores obtained at study visits. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Change in the weekly Opioid Related Symptom Distress Scale at Weeks 2, 4, 6, 12 and 16. [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Change from Baseline to Weeks 1, 2, 4, 6, 8, 12 and 16, in the Brief Pain Inventory (BPI) average pain scores obtained at study visits. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Anti-Drug Antibody testing at Baseline and Weeks 4, 6, 12 and 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Adverse events from time of first dose of study treatment through the last patient visit. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Patient's Global Evaluation of Study Medication at Weeks 1, 2, 4, 6, 8, 12 and 16. [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Average daily opioid consumption (up to Week 16). [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • ECG at Baseline (predosing and 1 hr post-dose) and Weeks 4 and 16 (or at early termination). [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
