Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mean Change in Average Daily Pain [ Time Frame: 1 year ]
    Numeric Rating Scale (NRS) for Pain (0-10; where 0 = no pain, 10 = worst pain imaginable) recorded up to 54 weeks, starting at screening through end of study. Lower number equals better outcome.


Secondary Outcome Measures :
  1. Maintenance of Efficacy [ Time Frame: 1 year ]
    Clinic Numeric Rating Scale (NRS), Brief Pain Inventory (BPI), Oswestry Disability Index, Hospital Anxiety and Depression Scale, Rescue Doses and Subject Global of Medication

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must have a diagnosed moderate to severe chronic pain condition treated with around-the-clock opioids for at least the past 3 months or in the Investigator's opinion qualify for around-the-clock opioid therapy for treatment of their pain
  • Subjects must have been taking opioids at least 5 days/week for the past month at an average daily dose of at least 30 mg hydrocodone
  • Subjects must be able to complete study procedures and attend clinic visits for 6 to 12 months
  • Females subjects of childbearing potential must have a negative urine pregnancy test at the Screen Visit, and must consent to use a medically-acceptable method of contraception throughout the entire study period.
  • Subjects must have had an adequate medical evaluation for the treatment of their underlying painful condition and appropriate primary medical/surgical therapies for the underlying condition
  • Subjects must voluntarily provide written informed consent

Exclusion Criteria:

  • Any clinically significant condition that would, in the opinion of the investigator, preclude study participation or interfere with the assessment of pain or increase the risk of opioid-related adverse events (AEs)
  • A medical condition that, in the opinion of the Investigator, would compromise the subject's ability to swallow, absorb, metabolize, or excrete study drug
  • A surgical procedure for pain within the last 3 months
  • Uncontrolled blood pressure, i.e., a sitting systolic blood pressure >180 mm Hg or <90 mm Hg, and/or a sitting diastolic blood pressure >120 mm Hg or <50 mm Hg at Screening
  • A body mass index (BMI) > 45 kg/m2
  • A hospital anxiety and depression scale (HADS) score of >12 in either depression or anxiety subscales or an established history of any psychiatric disorder that is poorly controlled
  • A clinically significant abnormality in clinical chemistry, hematology or urinalysis
