详细描述
Study Design (Methodology):
This will be a multicenter, phase IV, interventional study to assess the efficacy and safety of TARGIN(R)(Oxycodone/Naloxone) in Korean patients who are dissatisfied with their current analgesic medication (WHO step II analgesics).
Upon providing written informed consent, subject will be screened in the study and assessment will be performed at that time such as safety laboratory assessments, physical examination, vital sign, medical history taking, 24 hours pain intensity score, EQ-5D, physician's overall satisfaction and subject's overall satisfaction. If patient is eligible in inclusion/exclusion criteria at the time of visit 1, the patient will receive treatment with TARGIN(R). Re-screening, study drug dose interruption is not allowed. The duration of study drug dose interruption is defined as for 1 week.
Treatment with TARGIN(R) will be started at 5/2.5mg b.i.d.,and proper titration (up titration) will be allowed at each visit or at unscheduled visit according to the investigator's decision. On-site visit or phone call will be allowed for visit 2(wk 1).The up titration will be considered by investigator's judgement as followings; (1) if the rescue medication was used more than 2 times per day, on average or (2) based on the daily average numerical rating scale
, if the numerical rating scale was changed to worsen since the previous visit, (3) Investigator's judgement by considering any titration needed situation (e.g. dose, frequency of rescue medication). Pain assessment by investigator at each visit will be used for analysis and criteria for uptitration. Daily pain diary will be used for only criteria for uptitration.

- •Targin(R) product contains lactose. Patients with rare hereditary problems of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption should not take
- •Abnormal aspartate aminotransferase (AST; SGOT), alanine aminotransferase (ALT; SGPT), or alkaline phosphatase levels (>2.5 times the upper limit of normal, it is allowed >5 times the upper limit of normal in case of transition in liver) or an abnormal total bilirubin and/or creatinine level (s)(greater than 1.5 times the upper limit of normal), gamma glutamyl transpeptidase (GGT or GGTP) ≥ 3 times the upper limit of normal
- •Patients with uncontrolled seizures
- •Requiring interventional treatment for pain such as neurodestructive procedure or regional infusion
- •Patients with increased intracranial pressure
- •In the investigator's opinion, subjects who are receiving hypnotics or central nervous system (CNS) depressants that may pose a risk of additional CNS depression with opioid study medication
- •Patients with myxodema, not adequately treated hypothyroidism or Addisons disease
- •Patients receiving opioid substitution therapy for opioid addiction (e.g. methadone or buprenorphine)
- •Clinically significant impairment of cardiovascular, respiratory and renal function
- •Major surgery within 1 month prior to screening or planned surgery
- •Mainly pain originated other than spinal disorders disease
- •Non-malignant patients or cancer patients who are receiving any oncology treatment that could affect the measure of pain control
- •Patients with uncontrolled constipation regardless of laxative use and/or laxative type
- •With a disability that may prevent the patient from completing all study requirements and in particular, interfere with 24hrs pain intensity score
- •Patients known to have, or suspected of having a history of drug abuse
- •Patients with history of opioid or drug dependence
- •Any situation where opioids are contraindicated
- •Patient who needs acute dose titration or whose pain intensity fluctuate significantly in a short period according to investigator's judgment
- •Having used other investigational drugs at the time of enrollment
- •No additional exclusions may be applied by the investigator, in order to ensure that the study population will be representative of all eligible patients.

结局指标
主要结局
Change From Baseline in Pain Intensity of Patient With Spinal Disorder as Measured by NRS.
时间窗: Baseline, 8 week
NRS-Pain scale assessed the severity of a subject's pain of mean pain over the past 24 hours prior to the visit on a scale of 0 (No pain) and 10 (Worst possible pain). Change = mean score at Week 8/ET minus mean score at Baseline.
次要结局
- The Change in Quality of Life (EQ-5D) at Week 8 of Treatment With the Study Drug From Baseline(Baseline, 8 week)
- Clinical Global Impression of Change(CGIC)(Baseline, 8 week)
- Change of Pain Intensity in Patient With Spinal Disorder at Week 4 of Treatment With the Study Drug From Baseline(Baseline, 4 week)
- Patient Global Impression of Change(PGIC)(Baseline, 8week)
- Change From Baseline in Health-related Quality of Life Assessed by EuroQol Visual Analog Scale (EQ-5D VAS)(Baseline, 8 weeks)
