Primary Outcome Measures:
  • Sum of Pain Intensity Difference (SPID) of Treatment and Placebo at 4 Hours [ Time Frame: Up to 4 hours post dose ]
    SPID was calculated as the weighted sum of Pain (Headache) intensity differences at 4 hours post dose. The time-intervals used were 0-10, 10-15, 15-20, 20-25, 25-30, 30-40, 40-50, 50-60, 60-90, 90-120, 120-180, 180-240 minutes. The range of SPID at 4 hours post dose was from -12 to 4". PID was calculated as difference of pain intensity (PI) at baseline (prior to the first dose) with PI at a given time point. PI was assessed on a 4-point scale (0-no headache, 1-mild headache, 2-moderate headache, 3-severe headache).


Secondary Outcome Measures:
  • Sum of Pain Intensity Difference (SPID) at 1, 2 and 3 Hours [ Time Frame: From (Baseline) 0 to 1 hour, 0 to 2 hours, and 0 to 3 hours post dose ]

    SPID was calculated as the weighted sum of Pain (Headache) intensity differences at 1, 2 and 3 hours post dose.

    The time-intervals used were 0-10, 10-15, 15-20, 20-25, 25-30, 30-40, 40-50, 50-60 minutes for SPID at 1 hour post dose. The range of SPID at 1 hour post dose was from -3 to 1. The time-intervals used were 0-10, 10-15, 15-20, 20-25, 25-30, 30-40, 40-50, 50-60, 60-90, 90-120 minutes for SPID at 2 hours post dose . The range of SPID at 2 hours post dose was from -6 to 2. The time-intervals used were 0-10, 10-15, 15-20, 20-25, 25-30, 30-40, 40-50, 50-60, 60-90, 90-120, 120-180 minutes for SPID at 3 hours post dose. The range of SPID at 3 hours post dose was from -9 to 3. PID was calculated as difference of pain intensity (PI) at baseline (prior to the first dose) with PI at a given time point. PI was assessed on a 4-point scale (0-no headache, 1-mild headache, 2-moderate headache, 3-severe headache).


  • Number of Participants With Perceptible Pain Relief [ Time Frame: Baseline up to 4 hours ]
  • Time to Perceptible Headache Relief [ Time Frame: Baseline up to 4 hours ]
    Time to perceptible headache relief was assessed as the time when participants achieve pain relief scores (PRS) more than or equal to 1.

  • Number of Participants With Meaningful Pain Relief [ Time Frame: Baseline up to 4 hours ]
  • Time to Meaningful Headache Relief [ Time Frame: Baseline up to 4 hours ]
    Time to meaningful headache relief was assessed as time when participants reported a PRS ≥ 2.

  • Total Pain Relief (TOTPAR) [ Time Frame: From (Baseline) 0 to 1, from 0 to 2, from 0 to 3 and from 0 to 4 hour post dose ]
    TOTPAR was calculated as the weighted sum of pain relief scores (PRS) at each time point. PRS was assessed on a 5-point scale (0-no relief, 1-a little relief, 2-some relief, 3-a lot of relief, and 4-complete relief). The range for TOTPAR for different time points were as follows: from 0 to 4 for TOTPAR at 1 hour post dose, from 0 to 8 for TOTPAR at 2 hours post dose, from 0 to 12 for TOTPAR at 3 hours post dose, and from 0 to 16 for TOTPAR at 4 hours post dose.

  • Area Under the Time-Response Curve for Change in Headache Intensity and Headache Relief (SPRID) [ Time Frame: From (Baseline) 0 to 1 hour, 0 to 2 hours, 0 to 3 hours and 0 to 4 hours post dose ]
    SPRID was measured as sum of TOTPAR and SPID. SPID and TOTPAR were calculated as weighted sums of PID and PRS at each measurement time point, respectively. PID at each time point was calculated as difference of PI at baseline (prior to the first dose) with PI at a given time point. PI was assessed on a 4-point scale (0-no headache, 1-mild headache, 2-moderate headache, 3-severe headache). PRS was assessed on a 5-point scale (0-no relief, 1-a little relief, 2-some relief, 3-a lot of relief, and 4-complete relief). The range of SPRID for different time points were as follow: from-3 to 5 for SPRID at 1 hour post dose, from -6 to 10 for SPRID at 2 hours post dose, from -9 to 15 for SPRID at 3 hours post dose, and from -12 to 20 for SPRID at 4 hours post dose.

  • Global Evaluation of Response to Treatment [ Time Frame: 4 hours ]
    Global evaluation of treatment response was measured by a score in a scale from: 0-very poor, 1-poor, 2-neutral [neither poor nor good], 3-good, or 4-very good).

  • Rate of Rescue Medication [ Time Frame: 4 hours ]
    Number of participants that took rescue medication over the total number of participants for a given treatment group

  • Change From Baseline in Headache Pain Intensity [ Time Frame: At 10, 15, 20, 25, 30, 40, 50, 60, 90, 120, 180, and 240 min. ]
    Change from baseline in headache pain intensity was calculated as the change (difference) from baseline PI with PI at each time-point. PI was assessed on a 4-point scale (0-no headache, 1-mild headache, 2-moderate headache, 3-severe headache).

  • Headache Relief [ Time Frame: At 10 min. 15 min., 20 min., 25 min., 30 min., 40 min., 50 min., 60 min., 90 min., 120 min., 180 min., 240 min., ]
    The participant assessed headache relief of each treated qualifying headache at 10, 15, 20, 25, 30, 40, 50, 60, 90, 120, 180, and 240 minutes post treatment on a 5-point scale (0-no relief, 1-a little relief, 2-some relief, 3-a lot of relief, and 4-complete relief). higher headache relief score indicates better outcome.

  • Number of Pain Free Participants [ Time Frame: 1 hour and 2 hour post dose ]
    Number of participants with complete relief was calculated as the number of participants who reported PRS = 4-complete relief at 1 hour and 2 hours post dose.

  • Time to the Use of Rescue Medication. [ Time Frame: Up to 4 hours ]
    Time taken by the participants to use the rescue medication
