Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of fentanyl one-day transdermal patch (JNS020QD, patch containing a drug that is put on the skin so the drug will enter the body through the skin) in participants with chronic (lasting a long time) pain.

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 4 periods: Screening period (3-14 days), Treatment period 1 (4 weeks), Treatment period 2 (48 weeks), Tapering period (0-6 weeks) and Follow-up period (1 week). Treatment will be initiated at 12.5 microgram per hour (mcg/hr). In both Treatment period 1 and 2, the dose will be increased as per the Investigator's discretion, ranging from 12.5 mcg/hr to 100 mcg/hr and the maximum application dose will be 300 mcg/hr. However, in Treatment period 2, the dose will be increased on 7th day before the day of medical examination (only if the participant used rescue treatment for minimum of 3 times per day for minimum of 4 days). The patch will be applied on areas including the chest, abdomen, upper arm and femoral region and replaced daily. Efficacy will primarily be evaluated by visual analog scale (VAS) score. The total duration of the study treatment will be 52 weeks. Participants' safety will be monitored throughout the study.

Eligibility

Inclusion Criteria:

• Participants with chronic pain continuing for at least 12 weeks before informed consent

• Participants with an average pain intensity of greater than or equal to 50 millimeter (mm) on the Visual Analog Scale in 24-hour daily living before informed consent

• Participants who can be hospitalized to the 4th day after the initiation of patch application

• Participants who were given a sufficient explanation about the investigational product and the study and gave their own consent to participate in the study

Exclusion Criteria:

• Participants whose main cause of the pain to be assessed is considered attributable to psychogenic pain

• Participants with severe respiratory function disorders

• Participants with asthma (breathing disorder in which there is wheezing and difficulty breathing) and bradyarrhythmia (slow, irregular heartbeats)

• Participants with hepatic dysfunction function such as fulminant hepatitis (inflammation of the liver) and liver cirrhosis (serious liver disorder in which connective tissue replaces normal liver tissue, and liver failure often occurs), or renal impairment such as nephritic syndrome, acute renal failure, and chronic renal failure

• Participants with organic disorder in the brain such as brain tumor who have any of these symptoms: intracranial pressure increased, consciousness disturbance or coma and respiratory disorder

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Questionnaire of Opioid Withdrawal Symptoms	Questionnaire of opioid withdrawal symptoms is a clinician rated 11-item scale that primarily evaluates the physical components of opioid withdrawal and is based on questions and clinical observations. The total score of questionnaire of opioid withdrawal symptoms is the sum of all individual items, with less than (<) 5 points = no withdrawal, 5 to 12 points = mild withdrawal, 13 to 24 points = moderate withdrawal, 25 to 36 points = moderately severe withdrawal and greater than (>) 36 points = severe withdrawal.	Week 52 or endpoint (1 week after last treatment or early discontinuation)	Yes
Primary	Dependence Questionnaire (DQ)	The DQ is a clinician rated 5-item scale that evaluates dependence on drug and based on questions (Q). Based on participant's answer to Q in questionnaire, Investigator assessed whether drug dependence occurred. It comprises 5 Q which are: continuing drug for reason other than pain, using drug in more dosage than prescribed to have effect other than treatment of pain, have ever used drug with more dosage than prescribed for other purpose, anxiety with the thought of stopping drug for reason other than aggravation of symptoms by stopping this drug and feeling to violate law to get this drug.	Week 52 or end point (early discontinuation)	Yes
Primary	Pain Visual Analogue Scale Score	Pain visual analog scale was used to assess the amount of pain experienced by the participant throughout the day by marking a slash through the line of a 100 millimeter (mm) scale measuring pain from "no pain (0 mm)" to "worst possible pain (100 mm)".	Week 52 or end point (early discontinuation)	No
Primary	Number of Participants With Pain Assessed by Categorical Scale for Pain	Pain intensity was measured by assessing the average intensity of pain experienced by the participant in daily living throughout the day by 4 grades: no pain at all, mild (slightly painful, but not worried), moderate (painful, but bearable) and severe (painful and unbearable).	Week 52 or final evaluation (early discontinuation)	No
Primary	Number of Participants With Total Painful Time Per Day	The participants assessed total painful time in 1 day by the following 5 grades: less than 4 hours, 4 hours to less than 8 hours, 8 hours to less than 12 hours, 12 hours or more and all day.	Week 52 or final evaluation (early discontinuation)	No
Primary	Number of Participants With Quality of Sleep	The quality of sleep was assessed by participants that how well they have slept from the previous assessment to current assessment time by the following 4 grades: can sleep well, can sleep moderately well, cannot sleep much and cannot sleep at all.	Week 52 or final evaluation (early discontinuation)	No
Primary	Number of Rescue Treatments	Rescue treatment was used for participants with lack of analgesic efficacy, to have relief from breakthrough pain and in cases where withdrawal symptoms occur. The reference one-time rescue dose used was oral morphine 5 milligram (mg) for the investigational product fentanyl one-day transdermal patch 12.5 mcg per hr. The number of rescue treatments per day were reported.	Week 52 or final evaluation (early discontinuation)	No
Primary	Short-Form 36-Item Health Survey (SF-36) Scores	The SF-36 is 36-item form related to 8 health concepts (physical functioning, role physical, role emotional, general health, social functioning, bodily pain, vitality, mental health) and 2 summary scores (physical and mental component summary). Physical functioning, role physical and bodily pain contribute to physical component; role emotional, social functioning and mental health contribute to mental component; and social functioning, vitality, and general health contribute to both. All scores are based on a scale from 0 to 100, with higher scores defining more favorable health state.	Week 52 or final evaluation (early discontinuation)	No
Primary	Physician's Global Assessment Scale	The treating physician assessed the therapeutic efficacy of the treatment by 2 grades: effective and ineffective. Numbers of participants with effective and ineffective therapeutic efficacy with the treatment were reported.	Week 52 or final evaluation (early discontinuation)	No
Primary	Participants Overall Assessment	The participants assessed their satisfaction with therapeutic efficacy by 5 grades: satisfied very much, satisfied, equivocal, dissatisfied and dissatisfied very much. Percentage of participants who were at least satisfied (satisfied, satisfied very much) or at least neither satisfied nor dissatisfied (dissatisfied, dissatisfied very much) were reported.	Week 52 or final evaluation (early discontinuation)	No
Primary	Brief Pain Inventory-Short Form (BPI-SF) Total Score	The BPI-SF is a self-report questionnaire designed to assess the severity and impact of pain on daily functions. It includes pain interference score which is mean value for scores for 9 BPI-SF questions ranging between 0 (does not interfere) to 10 (completely interferes) and pain subscale score which is mean value for scores for BPI-SF questions 3 to 6 ranging between 0 (no pain) to 10 (pain as bad as can imagine). Total BPI-SF score is an average of pain interference score and pain subscale score and ranges from 0 to 10; higher score indicates more pain or pain interference.	Week 52 or final evaluation (early discontinuation)	No
