Study Endpoints

Primary Endpoints

Sum of the Pain Intensity Differences (SPID) Over 24 Hours
Over 24 hours post first dose

Pain intensity was measured on VAS (from 0 mm to 100 mm: 0 = no pain, 100 = worst possible pain). For each post dose time point, pain intensity difference (PID) is derived by subtracting the pain intensity at the post dose time point from the baseline intensity score (baseline score - post-baseline score). A positive difference is indicative of improvement. SPIDs was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values over the specific time period. SPID over 24 hours ranges from -2400 to 2400. A higher value indicates a better pain reduction.

Sum of the Pain Intensity Differences (SPID) Over 48 Hours
Over 48 hours post first dose

Pain intensity was measured on VAS (from 0 mm to 100 mm: 0 = no pain, 100 = worst possible pain). For each post dose time point, PID is derived by subtracting the pain intensity at the post dose time point from the baseline intensity score (baseline score - post-baseline score). A positive difference is indicative of improvement. SPIDs was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values over the specific time period. SPID over 48 hours ranges from -4800 to 4800. A higher value indicates a better pain reduction.

Sum of the Pain Intensity Differences (SPID) Over 72 Hours
Over 72 hours post first dose

Pain intensity was measured on VAS (from 0 mm to 100 mm: 0 = no pain, 100 = worst possible pain). For each post dose time point, PID is derived by subtracting the pain intensity at the post dose time point from the baseline intensity score (baseline score - post-baseline score). A positive difference is indicative of improvement. SPIDs was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values over the specific time period. SPID over 72 hours ranges from -7200 to 7200. A higher value indicates a better pain reduction.

Sum of the Pain Intensity Differences (SPID) Over 96 Hours
Over 96 hours post first dose

Pain intensity was measured on VAS (from 0 mm to 100 mm: 0 = no pain, 100 = worst possible pain). For each post dose time point, PID is derived by subtracting the pain intensity at the post dose time point from the baseline intensity score (baseline score - post-baseline score). A positive difference is indicative of improvement. SPIDs was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values over the specific time period. SPID over 96 hours ranges from -9600 to 9600. A higher value indicates a better pain reduction.

Sum of the Pain Intensity Differences (SPID) Over 120 Hours
Over 120 hours post first dose

Pain intensity was measured on VAS (from 0 mm to 100 mm: 0 = no pain, 100 = worst possible pain). For each post dose time point, PID is derived by subtracting the pain intensity at the post dose time point from the baseline intensity score (baseline score - post-baseline score). A positive difference is indicative of improvement. SPIDs was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values over the specific time period. SPID over 120 hours ranges from -12000 to 12000. A higher value indicates a better pain reduction.
