Participant Flow

Study dates: 27-Jun-2007 (first patient first visit) to 24-Jul-2008 (last patient last visit), at 86 medical/research sites in the USA.

The open-label run-in period (N = 1024 started) was designed to select subjects for randomization in the double-blind phase who met both tolerability and responsiveness criteria for either BTDS 10 or 20 (an enriched design).

Open-label Run-in Period
The open-label run-in period (\< 27 days) (N = 1024 started) was designed to select subjects for randomization who met both tolerability and responsiveness criteria for either BTDS 10 or 20 (an enriched design). Upon completion of the run-in period, 541 subjects were randomized and received treatment in the double-blind phase. Two subjects had no safety data after the randomization visit; therefore N = 539 for the randomized safety population.
Double-blind BTDS 10 or 20
Buprenorphine transdermal patch (BTDS) 10 mcg/h or 20 mcg/h applied for 7-day wear during the 12-week double-blind phase.
Double-blind Placebo TDS
Matching placebo transdermal patch (placebo TDS) 10 or 20 mcg/h applied for 7-day wear during the 12-week double-blind phase.

PRIMARY outcome

Timeframe: Prerandomization phase consisted of a 6-10 day screening period and a <27 day open-label run-in period; and a 12-week double-blind phase.

Population: The full analysis population (FAP) (N = 541) \[539\] consisted of subjects who were randomized and received at least 1 dose of the double-blind study drug. (Two subjects did not have safety data.)

Pain was assessed on an 11-point numerical scale ranging from 0 = no pain to 10 = pain as bad as you can imagine.

SECONDARY outcome

Timeframe: Weeks 4, 8, 12 of double-blind phase

Population: The full analysis population (FAP) (N = 541) consisted of subjects who were randomized and received at least 1 dose of the double-blind study drug. 2 subjects did not have safety data (N = 539).

The MOS Sleep Scale consists of 12 individual items (4 sleep disturbance, 2 sleep adequacy, 1 quantity of and optimal sleep, 3 somnolence, 1 snoring, and 1 shortness of breath) and takes 5 to 10 minutes to complete. Question 1 is scored on a scale of 1 to 5 and Questions 2 to 12 are scored on a scale of 1 to 6. The Sleep Disturbance Subscale score is derived from the scores to Questions 1, 3, 7 and 8, and ranges from 0 to 100, where higher scores indicate greater sleep disturbance.
