- •nonneuropathic conditions and may be with or without radiaton (Quebec
- •Task Force Classification 1 to 3)
- •3. Subjects must be - On ongoing opioid analgesic medication for at least 4 weeks prior to the screening visit (visit 1) and on a stable dose of opioid analgesic medication equivalent to 20 to 160 mg (inclusive) of morphine per day for the last 2 weeks prior to the screening visit (visit 1)
- •Taking 0 to less than 20 mg of morphine or its equivalent per day for the last 2 weeks prior to the screening visit (visit 1) due to OIC
- •4. Subjects must require opioid analgesic treatment in the range of 40 to 160 mg (inclusive) of morphine or its equivalent daily and be likely to benefit from chronic around-the-clock opioid therapy for the duration of the study.
- •5. Subjects must have an average pain over the last 14 days score = 5 at the screening visit
- •6. Subjects must have an average pain over the last 24 hours score = 5 at the screening visit
