Sponsor: Purdue Pharma L.P. (PPLP)
Study Drug: Buprenorphine = Subutex = Temgesic = Buprenex BTDS = Buprenorphine Transdermal System: 5, 10 & 20

Mu-opioid agonist-related AE’s: nausea, vomiting, dizziness, dry mouth, somnolence and constipation
Rescue Drug: ibuprofen 200 or Tylenol if intolerant to ibuprofen
Central IRB: Coast
Central Lab: LabCorp
Site #: 114A
Investigator #: 2384
First Patient: 64001
Alliance Call Center
Phase 3
723 Subjects/60 Sites = 12 Subjects per Site (241 Subjects R in each of the three groups: BTDS 5, BTDS 20 or OxyIR® 10 q 6h)

IC
Age: 18 years & older
Clinical Dx LBP x 3 months confirmed by X-Ray
Currently on MS 30-80 mgm per day at least 4 days a week for the last month

EC
Other chronic painful conditions frequently requiring analgesic therapy
Unstable Steroids less than 6 weeks
Intra-articular steroid x 6 wks or Hylagan or Synvisc
Workman’s compensation or other litigation

The Extension Phase
24 wk (6 month) open-label extension using BTDS 5, 10 and 20 to evaluate the long-term safety and tolerability of BTDS.
72 h later may increase BTDS 10 Patch
72 h after that increase BTDS 20 Patch
OK to use short acting opioids for breakthrough pain
