Outcomes
Primary Outcome Measures
Time Weighted Sum of Pain Intensity Differences (SPID) in Sore Throat Pain Intensity Scale (STPIS) Over the 24 Hours Post-baseline (STPIS SPID24)
STPIS measures sore throat pain intensity on a 100-mm visual analog scale completed by participants. A mark at 0-mm indicates no pain upon swallowing and 100-mm indicates severe pain. SPID24 was calculated as the sum of the time-weighted pain intensity differences from baseline until 24 hours. The full range was -114609 (complete pain relief within 2 minutes of dosing that lasts 24 hours) to 29191 (maximum pain within 2 minutes lasting 24 hours) using the mean baseline STPIS. Participants with a last recorded time point <21 hours were considered Not Evaluable. If a participant used rescue medication, all post-rescue STPIS values in the 24-hour interval were assigned the baseline value for STPIS. Missing scores of STPIS with non-missing STPIS scores at earlier and later assessments were imputed using linear interpolation assuming the time of the missing assessment to be the nominal time since initial dose.
Secondary Outcome Measures
Time Weighted Sum of Pain Intensity Differences (SPID) in Sore Throat Pain Intensity Scale (STPIS) Over the 2 Hours Post-baseline (STPIS SPID2)
STPIS measures sore throat pain intensity on a 100-mm visual analog scale completed by participants. A mark at 0-mm indicates no pain upon swallowing and 100-mm indicates severe pain. SPID2 was calculated as the sum of the time-weighted pain intensity differences from baseline until 2 hours post dosing. The full range was -9405 (complete pain relief within 2 minutes of dosing that lasts 2 hours) to 2395 (maximum pain within 2 minutes lasting 2 hours) using the mean baseline STPIS.
If a participant used rescue medication (acetaminophen 650mg was allowed as needed post dose), all post-rescue STPIS values in the 24-hour interval were assigned the baseline value for STPIS. Missing scores of STPIS with non-missing STPIS scores at earlier and later assessments (recorded or derived due to rescue) were imputed using linear interpolation assuming the time of the missing assessment to be the nominal time since initial dose.
Time Weighted Summed Differences in Difficulty Swallowing Scale (DSS) During the Initial 2 Hours From Baseline
Participants were asked to evaluate his/her difficulty swallowing (dysphagia) using a 100-mm visual analog scale at Baseline and 2 hours post dose.
Participants were instructed to swallow and "Place a line on the scale that best characterizes how difficult it is to swallow now." A mark at 0-mm indicated no difficulty and 100-mm indicated very difficult. Data is reported as the sum of the time-weighted pain intensity differences from baseline until 2 hours post dose. The full range was -9192 (no difficulty swallowing within 10 minutes of dosing that lasts 2 hours) to 2808 (maximum difficulty swallowing within 10 minutes lasting 2 hours) using the baseline DSS value.
Missing values of DSS with non-missing values at assessments before and after were calculated using linear interpolation.
Time Weighted Summed Differences in Difficulty Swallowing Scale (DSS) During the Initial 24 Hours From Baseline
Participants were asked to evaluate his/her difficulty swallowing (dysphagia) using a 100-mm visual analog scale at Baseline and until 24 hours post dose.
Participants were instructed to swallow and "Place a line on the scale that best characterizes how difficult it is to swallow now." A mark at 0-mm indicated no difficulty and 100-mm indicated very difficult. Data is reported as the sum of the time-weighted pain intensity differences from baseline until 24 hours post dose. The full range was -110304 (no difficulty swallowing within 10 minutes of dosing that lasts 24 hours) to 33696 (maximum difficulty swallowing within 10 minutes lasting 24 hours) using the baseline DSS value.
Missing values of DSS with non-missing values at assessments before and after were calculated using linear interpolation.
Time Weighted Summed Differences in Swollen Throat Scale (SwoTS) During the Initial 2 Hours From Baseline
The participant was asked to evaluate how swollen his/her throat felt using a 100-mm visual analog scale at Baseline and at 1 hour, 70 minutes, 80 minutes, 90 minutes, 100 minutes, 110 minutes, and 2 hours.
The patient was instructed to swallow and "Place a line on the scale that best characterizes how swollen your throat feels now." A mark at 0-mm indicated not swollen and 100-mm indicated very swollen. The full range of the sum of the time-weighted swollen throat differences from baseline until 2 hours was -9336 (throat did not feel swollen at all within 1 hour of dosing and lasted 2 hours) to 2664 (maximum swollen throat reported within 1 hour and lasting 2 hours) using the mean baseline SwoTS.
Time Weighted Summed Differences in Swollen Throat Scale (SwoTS) During the Initial 24 Hours From Baseline
The participant was asked to evaluate how swollen his/her throat felt using a 100-mm visual analog scale at Baseline and specified timeframes until 24 hours.
The patient was instructed to swallow and "Place a line on the scale that best characterizes how swollen your throat feels now." A mark at 0-mm indicated not swollen and 100-mm indicated very swollen. The full range of the sum of the time-weighted swollen throat differences from baseline until 24 hours was -112032 (throat did not feel swollen at all within 1 hour of dosing and lasted 24 hours) to 31968 (maximum swollen throat reported within 1 hour and lasting 24 hours) using the mean baseline SwoTS.
Change From Baseline at 24 Hours in the Tonsillo-Pharyngitis Assessment (TPA) Scores in Participants With Baseline TPA Scores >=8
Tonsillo-Pharyngitis Assessment, or TPA, is an index of seven clinical features of the pain-producing condition itself, pharyngeal inflammation. The clinical features concern temperature, oropharyngeal color, size of tonsils, number of enanthems, largest size of cervical lymph node, number of lymph nodes, and maximum tenderness of lymph nodes. Each variable was rated on a scale of 0-3, with 0 representing the normal value, and 3 representing severe inflammation. The seven values are added together to create the TPA, ranging from 0-21.
Negative change values represent improvement of symptoms.
Practitioner's Assessment of Pharyngeal Inflammation (P.A.I.N.) Scores at 24 Hours After Initial Dose
P.A.I.N is a four step scale in which physicians rate the severity of pharyngeal inflammation: No inflammation, mild, moderate and severe inflammation.
Investigators' Clinical Assessment (CLIN) Of Study Medication as a Treatment for Sore Throat at 24 Hours After Initial Dose
Investigators assessed the effectiveness of study medication on the patient's sore throat at 24 hours following initial dose by answering the following question: "Considering the patient's response to the study medicine over the past 24 hours, how do you rate the study medicine as a treatment for sore throat?" Responses were poor, fair, good, very good or excellent.
Participant Satisfaction Scores 24 Hours After Initial Dose
After 24 hours of treatment, participants rated their satisfaction with the treatment on a 7-step scale from extremely dissatisfied to extremely satisfied.
Investigators' Clinical Assessment (CLIN) Of Study Medication as a Treatment for Sore Throat at the End of the Study (Day 7)
Investigators assessed the effectiveness of study medication on the patient's sore throat at the end of the study by answering the following question: "Considering the patient's response to the study medicine over the past 7 days, how do you rate the study medicine as a treatment for sore throat?" Responses were poor, fair, good, very good or excellent.
Time Weighted Sum of Pain Intensity Differences (SPID) in Sore Throat Pain Intensity Scale Over 24 Hours Post-baseline (STPIS SPID24) For Participants With Baseline Practitioner's Assessment of Pharyngeal Inflammation (PAIN) of Moderate or Severe
STPIS measures sore throat pain intensity on a 100-mm visual analog scale completed by participants. A mark at 0-mm indicates no pain upon swallowing and 100-mm indicates severe pain. For the subgroup of patients with moderate/severe pharyngeal inflammation at baseline, SPID24 was calculated as the sum of the time weighted pain intensity differences from baseline until 24 hours. Taking inclusion criteria into account, the full range was -116196 (no pain at any post-dose time (0) - average baseline) to 27804 (maximum possible pain (100) - average baseline).
Participants with their last recorded time point <21 hours were considered Not Evaluable. If a participant used rescue medication (acetaminophen 650mg was allowed as needed), all post-rescue STPIS values in the 24-hour interval were assigned the baseline value for STPIS. Missing scores of STPIS with non-missing STPIS scores at earlier and later assessments were imputed using linear interpolation.
Sore Throat Relief Rating Scale (STRRS) At 2 Hours After Initial Dose
Participants used a 6-category relief scale (no relief to complete relief) to grade the relief of his/her throat pain.
The patient was instructed to swallow and:
"Considering how your throat felt before you took the study medicine, circle the phrase that best describes the relief of your sore throat now."
Time Weighted Sum of Pain Intensity Differences (SPID) in Sore Throat Pain Intensity Scale (STPIS) at Each Post-Dose Time Point Until the Time Point at Which Comparison of the Arms Yielded a P-value <=0.05
Data reported in summary form in Primary Outcome #1 are reported here at each post-dose timepoint until the comparison resulted in a P-value <=0.05 between the two treatment arms.
STPIS was used to measure sore throat pain intensity using a 100-mm visual analog scale completed by participants that measures "pain on swallowing" (odynophagia). A mark at 0-mm indicates no pain and 100-mm indicates severe pain. The full range of the scale varies by timepoint due to the time weighting sum of SPID. The full scale at 40 minutes post dose was -3188 (complete pain relief within 2 minutes of dosing that lasts 40 minutes) to 812 (maximum pain within 2 minutes lasting 40 minutes) using the mean baseline STPIS.
If a participant used rescue medication (acetaminophen 650mg was allowed as needed), all post-rescue STPIS values in the 24-hour interval were assigned the baseline value for STPIS. Missing scores of STPIS with non-missing STPIS scores at earlier and later assessments (rec
Kaplan-Meier Estimates for Sore Throat Pain Intensity Scale (STPIS) Time to Definite Improvement
As part of a protocol amendment, some participants defined a definite improvement level (DIL) relative to their actual pretreatment STPIS on the 100-mm visual analog scale. This was done after completing the 7 day trial.
An alternative definition of STPIS time to onset of relief was the time from initial dose to the time the participant reaching DIL for at least 30 minutes. Data were censored if DIL was not achieved by 120 minutes following initial dose. Definite improvement must also occur prior to re-dosing or using rescue medication.
Kaplan-Meier Estimates for Sore Throat Pain Intensity Scale (STPIS) Time to Definite Improvement Duration of Relief Using Participant-Defined Definite Improvement Levels (DIL)
As part of a protocol amendment, some participants defined a definite improvement level (DIL) relative to their actual pretreatment STPIS on the 100-mm visual analog scale. This was done after completing the 7 day trial.
The time of first achieving DIL for 30 minutes within 6 hours (or until rescue or re-dosing) post-dosing will be determined. And the time falling below DIL within 6 hours will be determined. Duration is then defined as the time from first DIL until falling below DIL. Duration was set to zero if the STPIS score does not reach the DIL for at least 30 minutes for STPIS during the 6 hours.
