Brief Summary:
The purpose of this study is to determine whether BEMA Buprenorphine is safe in the treatment of chronic pain.

Condition or disease Intervention/treatment Phase
Pain Low Back Pain Osteoarthritis Neuropathic Pain Drug: BEMA Buprenorphine Phase 3

Detailed Description:

This is an open label study of up to approximately 52 weeks duration to assess the safety and effectiveness of BEMA Buprenorphine in the management of moderate to severe chronic pain.

BEMA Buprenorphine is an oral transmucosal form of the opioid analgesic, buprenorphine hydrochloride, intended for application to the buccal mucosa. Buprenorphine is a synthetic opioid that is classified as a partial μ-receptor agonist and a Schedule III controlled substance in the United States.

Primary Outcome Measures :
  1. Change From Baseline in NRS Pain Intensity [ Time Frame: Baseline up to approximately Week 52 ]
    The NRS Pain intensity score is a segmented version of a visual analog scale used to measure pain. The scale is from 0 (no pain) to 10. Scores between greater than 0 and 3 are considered mild pain, scores from greater than 3 to 6 are moderate and greater than 6 to 10 are severe. The daily average is calculated and used to calculate the change from baseline at week 52.


Secondary Outcome Measures :
  1. Patient Global Impression of Change in Pain Intensity [ Time Frame: Baseline to Week 28 ]
    Patient Global Impression of Change in Pain Intensity at Week 28 as measured by a 7 point scale. Patients measure their improvement from 7='very much improved', 6='much improved', 5='minimally improved', 4='no change', 3='minimally worse', 2='much worse', 1='very much worse'.

  2. Treatment Satisfaction Questionnaire for Medication/Global Satisfaction [ Time Frame: Baseline to Week 28 ]
    Treatment Satisfaction Questionnaire for Medication/Global Satisfaction at Week 28. Patients complete a 14 item questionaire that measures 4 scales based on side effects, effectiveness, convenience and global satisfaction. All items have either five or seven responses (except item 4), scored from one (least satisfied) to five or seven (most satisfied). The 7-item scales have a non-neutral midpoint, such that there are more positive response options than negative response options. Item scores are summed to give four domain scores, which are in turn transformed to a scale of 0-100. Item 4 was not included for scoring. If an item score is missing and half of the items in the domain are complete, domain scores may be imputed from the person-specific mean score of completed items

  3. Subjects Overall Satisfaction With Study Drug [ Time Frame: Baseline to Week 52 ]
    Subjects Overall Satisfaction with Study Drug as measured on a 5 point scale, with 1 being not satisfied and 5 being very satisified.

  4. Investigator's Overall Satisfaction With Study Drug [ Time Frame: Baseline to Week 52 ]
    Investigator's Overall Satisfaction with Study Drug measured on a 5-point scale, with 1 being not satisfied and 5 being very satisfied.
