An Efficacy and Safety Study for Tapentadol Extended Release (JNS024ER) in Chronic Pain Participants

2013년 5월 10일 업데이트: Janssen Pharmaceutical K.K.

Phase II Study of JNS024ER in Japanese Subjects With Chronic Pain Due to Osteoarthritis of the Knee or Low Back Pain

The purpose of this study is to evaluate the efficacy, safety and to explore the pharmacokinetics (how drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time) of tapentadol hydrochloride extended release (ER) tablets in Japanese participants with moderate to severe chronic pain due to osteoarthritis (disorder in which the joints become painful and stiff) of knee or low back pain.

상세 설명

This is a randomized (study drug assigned by chance), multi-center (when more than one hospital or medical school team works on a medical research study), double-blind (neither physician nor participant knows the name of the assigned drug), placebo-control (participants are randomly assigned to a test treatment or to an identical-appearing treatment that does not contain the test drug), parallel-group (each group of participants will be treated at the same time) comparison study in participants with chronic pain due to osteoarthritis of knee or low back pain. The study duration will be of 14 weeks, which consists of a screening period of 1 week during which the participants will be evaluated for study eligibility, a treatment period of 12 weeks and a follow-up period of 1 week. The treatment period will consist of titration period (from the initiation of the study treatment to determination of the individual's maintenance dose) and maintenance period (from completion of the titration period to the completion of the treatment period). An optimal dose (maintenance dose) will be determined for each participant during the titration period and the treatment will be continued at the maintenance dose to assess the efficacy and safety. Tapentadol hydrochloride ER tablets 25 to 250 milligram or placebo will be administered orally twice daily. Efficacy and safety of the participants will primarily be evaluated by change from baseline in average pain intensity score based on 11-point Numerical Rating Scale (NRS) and Clinical Opiate Withdrawal Scale (COWS), respectively. Participants' safety will be monitored throughout the study.

Change From Baseline in 11-point Numerical Rating Scale (NRS) at Week 12
기간: Baseline, Week 12
Participants were asked to assess the average pain intensity on a 11-point NRS ranging from 0 (no pain) to 10 (maximum pain imaginable) by selecting a number applicable to their pain on the scale. The mean pain intensity during the past 74 hours (3 days) was evaluated at Baseline and the mean pain intensity during the past 12 hours was evaluated at subsequent study visits.
