Further study details as provided by Zogenix, Inc.:

Primary Outcome Measures:
  • 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:
  • 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

Enrollment: 424
Study Start Date: May 2010
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hydrocodone Bitartrate
Open-label, all patients fulfilling the protocol Inclusion/Exclusion criteria will receive HC-CR in a flexible dosing regimen.
Drug: Hydrocodone Bitartrate
Open-Label, Capsule Strengths 10 mg, 20 mg, 30 mg, 40 mg, 50 mg; by mouth (PO) twice a day (BID) for up to 48 weeks
Other Name: Hydrocodone Bitartrate Controlled Release (HC-CR)

Detailed Description:
Subjects will go through screening, an open-label conversion and titration phase of up to 6 weeks followed by an open-label treatment phase for up to 48 weeks with a 2 week follow-up period.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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
