Timeframe: 1, 1.5, 2, 3, 4, 5, 6, 24, 48 and 72 hours after Time 0

Population: In the ITT population using the mWOCF method of imputation, the differences in the mean summed pain intensity (SPI) VAS at-rest score

Summed pain intensity (SPI) (VAS at rest and after cough): - For the VAS assessment, patients measured their pain intensity at rest and after aggravated movement (cough) using a horizontal 100-mm VAS scale labeled as follows: No Pain (0 mm) as the left anchor and Worst Pain Imaginable (100 mm) as the right anchor. Each timepoint consist of two measurements (Resting \& Coughing) - The lower the score the better outcome for the patient. The highest total score (worst possible score) for the 10 timepoints would be 2000.
