Keywords: Osteoarthritis Transdermal Therapeutic System (TTS)-fentanyl Durogesic
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 35
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the efficacy and safety of Transdermal Therapeutic System (TTS)-fentanyl patch (transdermal patch containing a drug that is put on the skin so the drug will enter the body through the skin) in participants with moderate (medium level of seriousness) to severe (very serious, life threatening) pain of osteoarthritis (disorder, which is seen mostly in older persons, in which the joints become painful and stiff).

Detailed description:
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 following participants forward in time), study of TTS-fentanyl in participants with moderate to severe pain of osteoarthritis. The study will consist of 2 phases: screening phase up to 7 days before starting the treatment and treatment phase of 30 days. The first patch will be applied by investigator then by participants until 30 days. The dose of TTS-fentanyl can be increased, if needed, by 12.5 microgram per hour until adequate (reasonably good) pain control is achieved and taking into account the daily dose of supplemental paracetamol required by the participant. Other concomitant (given at the same time) analgesics (drug used to control pain) will not be used during this phase. Efficacy with regard to pain control will be recorded principally by the participant through 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.

Arms:
arm 1: 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.

Interventions: intervention 1: TTS-fentanyl
Intervention descriptions: intervention 1: 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.
