Exclusion criteria
Exclusion criteria: • Clinically relevant increasing daily doses of the non-opioid and opioid analgesic medication in the last 14 days prior to the start of the study and in the course of the study • Intake of any other strong opioids (step 3 WHO-Guidelines) in the course of the study • Clinically relevant increasing daily doses of co-analgesics, e.g. steroids, anticonvulsants and antidepressants in the last 14 days prior to the start of the study and in the course of the study • Non-pharmacological pain therapies, e.g. neurolysis, acupuncture, epidural anaesthesia • Planned surgery in the next 30 days or in the last 14 days prior to the start of the study • Any treatment which in the opinion of the responsible physician might have a clinically relevant influence on pain intensity • Patients with clinically significant impaired renal or hepatic function Study Code: BUP/006/C / Protocol Version Number: 4 / 2008/ 11th November Page 26 • Patients with a clinically relevant impairment of respiratory function including presence or history of chronic obstructive lung disorder or any other serious lung disease • Pregnancy or lactation • Women with child-bearing potential who do not apply a medically accepted safe method of contraception (e.g. sterilisation, oral contraception) • Known alcoholism or drug abuse • Patients with a known or suspected history of abuse of centrally acting substances • Patients with increased intracranial pressure including metastases in the CNS which could lead to respiratory depression • Present febrile state and regionally increased body temperature which could lead to increased plasma concentrations of buprenorphine • The subject or his family has a history of non-allergic drug reactions, of a drug allergy, or other allergy, which in the opinion of the responsible physician contraindicates the subject's participation in the study • The subject has a known or suspected personal history or family history of adverse reactions or hypersensitivity to buprenorphine or buprenorphine-like substances • Treatment with monoamine oxidase inhibitors in the last 14 days prior to the start of the active treatment phase • Patients suffering from myasthenia gravis • Significant skin lesions on arms (or other chosen area for patch application) or diffuse skin disease (e.g. diffuse psoriasis or eczema) • Subjects with a medical disorder, condition or history of such that would impair the subject’s ability to participate or complete this study in the opinion of the investigator • Participation in another clinical trial within one month prior to enrolment or during the course of the study • Relevant pathological changes in the ECG.

| Main Objective: Primary objective of the study is to demonstrate that the BUP-TDS applied every 96 hours (Treatment group A) is therapeutically non-inferior to BUP-TDS applied every 72 hours (Treatment group B). ;Secondary Objective: Secondary objectives of the study are: • Assessment of pain intensity during the day (8 am to 8 pm) and at night (8 pm to 8 am) with a 11-point numeric rating scale in each treatment group • Calculation of the mean number of sublingual tablets required as rescue medication • Calculation of the mean number of sublingual tablets required as rescue medication per day during the active treatment phase compared with the daily demand during the run-in phase in each treatment group • Duration of sleep undisturbed by pain in each treatment group • Assessment of safety and tolerability characteristics of BUP-TDS by measuring the frequency, severity, and type of adverse event • Assessment of dermal tolerability and adhesive properties of BUP-TDS by the Skin Irritation Score and the Adhesion Score (see Section 14.1 Scoring systems) ;Primary end point(s): To assess and compare the analgesic efficacy and tolerability of a buprenorphine transdermal system in two different application intervals using three different dosages (35, 52.5, or 70 µg/h). Assessment of safety and tolerability characteristics, and assessment of dermal tolerability and adhesive properties of BUP-TDS. | — |
