Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the present trial is the assessment of the efficacy of Fentanyl Nasal Spray in combination with an applicator as compared to placebo for the management of postoperative pain. Pain caused by orthopedic surgery will serve as a model for postoperative pain. Evidence from the literature will be used to bridge analgesic effectiveness of nasal fentanyl from pain primarily caused by activation of nociceptors to visceral pain (e.g. caused by abdominal surgery).;Secondary Objective: The secondary objective of the present trial is the assessment of the tolerability and side-effects of prolonged postoperative administration of Fentanyl Nasal Spray as compared with Standard of Care [morphine, applied by standard of care treatment via i.v. PCA (patient-controlled analgesia)]. Furthermore, the usability of the administration control device will be assessed.;Primary end point(s): The primary endpoint in the present trial is: Survival distribution in the period from start of treatment with the first dose of the study medication until terminating the trial due to inadequate analgesia as required by the patient or felt necessary by the investigator within the first 24 hours after start of treatment with non-terminating patients censored at 24 hours.;Timepoint(s) of evaluation of this end point: After the end of the clinical part of the trial. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary endpoints are: • sum of ratings of pain intensity on a 11-point numeric rating scale at pre-defined points in time: at hours 1, 2, 3, 4, 6, 8, 12, 16, 20, and 24 after start of treatment (TotPaR) • sum of pain intensity difference ratings on a 11-point numeric rating scale comparing the pain rating before start of treatment (0) and ratings at pre-defined points in time (SPID): at hours 1, 2, 3, 4, 6, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96, 108, and 120 after start of treatment (Patients will not be woken up for a postoperative measurement. The last observation carried forward method will be used to replace a missing value • percentage of patients who terminate the study due to inadequate analgesia during the 24-hours treatment period • percentage of patients who terminate the study due to any reason during the 24-hours treatment period • number of actuations administered • number of unsuccessful actuations during lock-out period • patient's rating of usability [System Usability Scale (SUS)] • patient’s global rating of efficacy using a four-point Likert scale (poor, fair, good, or excellent) • investigator's global rating of efficacy (Likert scale: see above) • evaluation of ease of care (patients, nursing staff, and physiotherapists).;Timepoint(s) of evaluation of this end point: After the end of the clinical part of the trial. | — |
