E.1.2 | Classification code | 10054711 |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of this trial is to demonstrate non-inferiority of oxycodone/naloxone prolonged release tablets (OXN) compared to piritramide infusions with respect to post operative pain intensity 3 hours after administering first oral or intravenous medication on day 1 post surgery (V2).
|
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of the study are: • To assess the differences between treatment groups in: – pain duration after surgery – efficacy variables (pain control, bowel function) • to assess the tolerability and safety of oxycodone/naloxone prolonged release tablets (OXN) as compared with piritramide infusions •to evaluate health economic aspects

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female patients at least 18 years or older.
2. Females of child-bearing age and females less than one year post-menopausal must have a negative serum pregnancy test recorded in the Screening Phase prior to the first dose of study medication, be non-lactating, and willing to use adequate and highly effective methods of contraception throughout the study (highly effective methods of birth control are defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as sterilization, implants, injectables, combined oral contraceptives, some hormonal intrauterine device, sexual abstinence or vasectomised partner).
3.Patients designated for laparoscopic cholecystectomy and suffering postoperatively from moderate to severe pain or from continuously increasing pain consecutively leading to moderate to severe pain. The Investigator expects that the pain will continue for a minimum of 2 days. Patients are eligible for randomization if one of the following criteria is met: a)Patient actively reports that she/he suffers from moderate to severe pain and rates a pain on a NRS ≥ 4. b)Patient actively reports that she/he suffers from an increasing pain and the Investigator expects that this pain will lead to moderate to severe pain and requires a treatment with a WHO step III opioid. c)If not actively reporting, the responsive patient will be asked in the recovery area to rate the current pain on the NRS. If the pain is rated with NRS ≥ 4, the patient will be randomized. If the pain is rated with NRS < 4, the patient will be asked whether she/he suffers from an increasing pain which is expected by the Investigator to lead to moderate to severe pain and to require a treatment with a WHO step III opioid.
4. Patients willing and able to participate in all aspects of the study, including use of oral or intravenous infusion medication, completion of patients’ evaluations (questionnaires), attending scheduled clinic visits and completion of all examinations, completion of telephone follow-up contact, and compliance with protocol requirements as evidenced by providing written, informed consent.
5. Patients willing to stop their laxative intake prior to study participation.

|
E.4 | Principal exclusion criteria |
1. Females who are pregnant (positive beta-hCG test), lactating or not willing to accept effective methods of contraception.
2. Patients with any history of hypersensitivity to oxycodone, naloxone, piritramide, bisacodyl and further ingredients of the study medications.
3. Patients with any contraindication to oxycodone, naloxone, piritramide, bisacodyl and further ingredients of the study medications.
4. Patients with any consuming disease.
5. Patients presently taking or having taken Monoamine Oxidase Inhibitors 14 days prior to the start of the Screening Period.
6. Patients with rare hereditary problems of galactose intolerance, lactase deficiency or glucose-galactose malabsorption.
7. Patients with evidence of impaired liver and kidney function upon entry into the study defined as aspartate aminotransferase (ASAT; SGOT), alanine aminotransferase (ALAT; SGPT), or alkaline phosphatase levels > 3 times the upper limit of normal; gamma glutamyl transpeptidase (GGT) 5 times the upper limit of normal; total bilirubin level outside of the reference range; and/or creatinine level outside of the reference range or > 2 mg/dL, or in the Investigator´s opinion, liver and/or kidney impairment to the extent that the patient should not participate in this study.
8. Patients with evidence of significant structural abnormalities of the gastrointestinal tract or any diseases/conditions that affect bowel transit.
9. Patients with evidence of any clinically unstable disease following the Investigator’s review of the medical history, physical examination and clinical laboratory tests, with the exception of those parameters which are resulting from the underlying basic disease, that would place the patient at risk upon exposure to the study medications or that may confound the analysis and/or interpretation of the study results.
10. Patients with an active alcohol or drug abuse and/or history of opioid abuse.
11. Patients receiving opioid substitution therapy for opioid addiction (e.g., methadone or buprenorphine).
12. Patients who participated in a clinical research study involving a new chemical entity or an experimental drug within 30 days of study entry (defined as the start of the Screening Period).
13. Patients who are committed by authorities or jurisdictionally to an institution according to the German Medicines Act (AMG) para 40 clause 1 p. 3 no. 4. |

E.5 End points |
E.5.1 | Primary end point(s) |
Pain intensity (NRS) 3 h after first study medication intake. Pain intensity will be assessed using a 0 to 10 numeric rating scale (NRS, see Appendix 12.10. CTP). Study staff will ask the patients 3 hours after first study medication intake on day 1 post-OP (Visit 2) and record subject’s pain intensity in the CRF.
