An Efficacy and Safety Study of Fentanyl (JNS020QD) in Participants With Cancer Pain

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the safety and efficacy of fentanyl one-day transdermal patch (patch containing a drug that is put on the skin so the drug will enter the body through the skin) in participants switched from morphine preparations, oral oxycodone preparations, fentanyl citrate injection or fentanyl patch for cancer pain.

Detailed Description
-----------------
This is an open-label (all people know the identity of the intervention), multi-center (conducted in more than one center) and non-comparative study of fentanyl one-day transdermal patch. The study consists of 3 periods: Pre-treatment observation period (4-7 days), Treatment period (10 days) and Follow-up period (2 days). Treatment will be initiated at 12.5 microgram per hour (mcg/hr) and the initial dose of fentanyl will be determined based on the daily dose of the opioid analgesic taken by the participant before entering the study and will be maintained for 2 days to ensure safety of participants. Dose escalation or reduction will be as per the Investigator's discretion from Day 3 to Day 7 and thereafter dose will be again maintained from Day 7 to Day 9, ranging from 12.5 mcg/hr-100 mcg/hr and the maximum application dose will be 300 mcg/hr. The patch will be applied on areas including the chest, abdomen, upper arm or thigh and will be replaced daily for 10 days (a total of 9 applications; including the day of final patch removal). Efficacy will primarily be evaluated by visual analog scale (VAS) score. Participants' safety will be monitored throughout the study.

Eligibility Criteria

| Experimental: Fentanyl<br> | Drug: Fentanyl<br>* Fentanyl 1-day application transdermal patch releasing the drug at the rate of 12.5 microgram per hour (mcg/hr) to 100 mcg/hr applied once daily, and maintained for 2 days.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving Pain Control | Pain control was assessed based on change in Visual Analog Scale (VAS) and number of daily rescue doses during 3 days before completion of study drug from 3 days before start of study drug. For VAS score, a difference of less than or equal to +15 millimeter (mm) and for rescue doses, a difference of less than or equal to 1 was considered significant to achieve pain control. Pain Intensity VAS ranged from 0 mm (no pain) to 100 mm (severest pain conceivable) and rescue dose was defined as dose of fast-acting opioid analgesic (except fentanyl preparations) used for lack of analgesic effect. | Day 10 or early discontinuation (ED) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Response Based on Patient's Global Assessment Scale | Participants were asked to assess their satisfaction with respect to the therapeutic efficacy (effectiveness) of the study drug on a 5-point scale ranging from 1 to 5, where 1 = extremely satisfied, 2 = satisfied, 3 = neither satisfied nor dissatisfied, 4 = dissatisfied and 5 = extremely dissatisfied. | Day 1, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10 or ED | 
| Pain Intensity Visual Analog Scale (VAS) Score | Participants were asked to assess their resting pain intensity (severity of pain) on a 100-mm VAS with the left edge (0 mm) defined as no pain and the right edge (100 mm) defined as severest pain conceivable. | Day 1 (pre-application), Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10 or ED | 
| Number of Participants With Pain Intensity Assessed by Categorical Scale for Pain | Participants were asked to assess their resting pain intensity (severity of pain) on a 4-point categorical scale ranging from 0 to 3 where 0 = no pain, 1 = mild pain, 2 = moderate pain and 3 = severe pain. | Day 1, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10 or ED | 
| Number of Participants With Total Duration of Pain Per Day | The participants assessed total painful time in 1 day on a 5-point scale ranging from 0 to 4 where 0 = less than (<) 4 hours, 1 = greater than or equal to (>=) 4 hours to less than 8 hours, 2 = greater than or equal to 8 hours to less than 12 hours, 3 = greater than or equal to 12 hours and 4 = 24 hours (all day). | Day 1, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10 or ED | 
| Mean Number of Rescue Doses | Rescue dose was defined as the dose of a fast-acting opioid analgesic (except fentanyl preparations) given in case of breakthrough pain or lack of analgesic effect. | Day 1, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10 or ED | 
| Number of Participants With Response Based on Physician's Global Assessment Scale | The treating physician assessed the therapeutic efficacy (effectiveness) of the study drug by 2-point scale of effective and ineffective. Number of participants with effective and ineffective therapeutic efficacy with respect to the study drug were reported. | Day 10 or ED |
