An Interventional Study to Assess the Efficacy and Safety of Buprenorphine in Korean Patients With Spinal Disorders

NCT ID: NCT01818700

Last Updated: 2015-10-22

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE4
• Total Enrollment: 245 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-09-30
• Study Completion Date: 2013-06-30

Brief Summary

The purpose of this study is to assess the pain reduction rate after 8 weeks treatment of NORSPAN® from baseline.

And secondary purpose are: pain reduction rate after 4 weeks treatment from baseline(week 0) the EQ-5D, the pain and sleep questionnaire, physician's overall satisfaction subject's overall satisfaction, and safety

Detailed Description

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, pain and sleep questionnaire, 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 NORSPAN®.

Treatment with NORSPAN® will be started from 5 μg/h (1 patch a week) for 2 weeks, and proper titration (up-titration) will be allowed at visit 2(wk 2) and at visit 3(wk 4) according to the investigator's decision.

Study Groups

Single arm-Norspan patch (Buprenorphine)

This trial is single arm with Norspan patch. Treatment with NORSPAN Ò will be started from 5 μg/h (1 patch a week) for 2 weeks, and proper titration (up-titration) will be allowed at visit 2(wk 2) and at visit 3(wk 4) according to the investigator's decision. The up-titration will be considered by investigator's judgement as follows; (1) if the rescue medication was used more than 2 times per day, on average or (2) based on the daily average NRS(Numeric Rating Scale), if the NRS 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).

Eligibility Criteria

Inclusion Criteria

• 20 years old or above male or female Korean patients
• Patients who have spinal disorders related pain
• Patients who had been treated with weak opioids and/or NSAIDs before study participation

• Patients who are concurrently taking other CNS depressants or muscle relaxants that may cause respiratory depression, hypotension, profound sedation or potentially result in coma.
• Patients who are taking Buprenorphine or strong opioid.
• Any situation where Buprenorphine is contraindicated
• 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
• With a disability that may prevent the patient from completing all study requirements and in particular, interfere with 24hrs pain intensity score
• Clinically significant impairment of cardiovascular, respiratory and renal function
