| Measure | Time frame |
|---|---|
| Main Objective: Main objective of the trial is to evaluate the efficacy, safety and effects on Quality of Life (QOL) of the medicines Doreta IR and Doreta SR produced by Krka, d.d., Novo mesto, Slovenia in patients with moderate to severe acute low-back pain.;Secondary Objective: Not applicable;Primary end point(s): The proportion of patients with clinically meaningful improvement of low back pain. Reduction of low back pain intensity is considered as clinically meaningful if pain intensity not exceeding 30 mm on VAS is achieved on the day of therapy discontinuation or at the end of the trial.;Timepoint(s) of evaluation of this end point: After 28 days of treatment | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary end points of the trial are: • Pain intensity difference (PID) at the end of dosing interval on day 6 (one endpoint). • Cumulative pain intensity (CPI) throughout the dosing interval (five endpoints). • Pain intensity difference between each control visit value and the baseline value at Visit 1 (three endpoints). • Quality of life difference (two endpoints). • Pain interference score difference (assessed by Brief pain inventory - Short form) between the value at each visit and the baseline value at Visit 1 (three endpoints). • Proportion of patients with excellent pain response (one endpoint). • Proportion of patients with reduced pain at each control visit (three endpoints). • Proportion of patients with eliminated pain: at each control visit (three endpoints). • Proportion of compliant patients, i.e. those having a compliance of more than 80 % at the regular therapy end visit (one endpoint).;Timepoint(s) of evaluation of this end point: After 28 days of treatment | — |
