Efficacy and Safety Study of Transdermal Therapeutic System (TTS) Fentanyl in Participants With Osteoarthritis Knee Pain
The purpose of this study is to evaluate the efficacy and safety of Transdermal therapeutic system (TTS) fentanyl patches (transdermal patch containing a drug that is put on the skin so the drug will enter the body through the skin) in knee osteoarthritis (disorder, which is seen mostly in older persons, in which the joints become painful and stiff) participants with moderate to severe pain.

|Official Title:||Evaluation of Efficacy and Safety of TTS-Fentanyl in Moderate to Severe Pain From Knee Osteoarthritis|
- Change From Baseline in Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) Score at Day 30 [ Time Frame: Baseline, Day 30 ] [ Designated as safety issue: No ]The WOMAC is a self administered, participant health related questionnaire consisting of three subscales (pain, stiffness and physical function). Pain subscale score ranges from 0-100 mm (0 mm=no pain to 100 mm=extreme pain); stiffness subscale score ranges from 0-100 mm (0 mm=no stiffness to 100 mm=extreme stiffness) and physical function subscale ranges from 0-100 mm (0 mm=no difficulty to 100 mm=extreme difficulty). The overall WOMAC score is the sum of the 3 subscale scores which ranges from 0-300 mm (0 mm=none to 300 mm=extreme/worst).

Transdermal therapeutic system (TTS) fentanyl patches releasing at the rate of 12.5 microgram per hour for 3 days. The patches will be replaced every 3 days until 30 days.

This is an open-label (a medical research study in which participants and researchers are told which treatments the participants are receiving, "unblinded"), single-arm, prospective study (study following participants forward in time) of TTS-fentanyl matrix form in knee osteoarthritis participants. The study consists of 3 phases: a screening phase, an open label treatment phase consisting of 2 periods, and an evaluation phase. The first patch will be applied on the first day of treatment phase by the investigator, and sufficient patches until Day 30 will be provided to the participant with the instructions to apply the patch. The TTS-fentanyl dose will normally be increased, if needed by 12.5 microgram per hour taking into account the daily dose of supplemental paracetamol required by the participant. Efficacy with regard to pain control will be recorded principally by the participant via questionnaires in a daily diary. This record will be used to support more detailed assessments at study visits on Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Participants' safety will be monitored.
