Trial Outcomes & Findings for A Study of Flurbiprofen 8.75 mg Lozenge in Patient With Pharyngitis (NCT NCT01049334)

NCT ID: NCT01049334

Last Updated: 2017-09-21

Results Overview

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.

PRIMARY outcome

Timeframe: baseline (pre-dose), 24 hours post-dose (every 2 minutes for one hour; every 10 minutes until hour 2; every 30 minutes until hour 6; and every hour the participant was awake between hours 7-24)

Population: Intent to treat population of participants who took the first full dose of medication. Three participants (1 Flurbiprofen, 2 Placebo) did not have sufficient 24 hour data to be included in the primary analysis of the primary endpoint (no entries after 2 hours), but did have sufficient data to be included in other efficacy analyses.

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.

Population: Intent to treat population of participants who took the first full dose of medication.

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.

Timeframe: Baseline (pre-dose), 24 hours post-dose

Population: Intent to treat population of participants whose baseline TPA was \>=8 and had an assessment at hour 24.

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.

Timeframe: baseline (pre-dose), 24 hours post-dose (every 2 minutes for one hour; every 10 minutes until hour 2; every 30 minutes until hour 6; and every hour the participant was awake between hours 7-24)

Population: Intent to treat population of participants who took the first full dose of medication and had moderate or severe pharyngeal inflammation at baseline.

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.

Timeframe: baseline (pre-dose), up to 23 hours post-dose (every 2 minutes for one hour; every 10 minutes until hour 2; every 30 minutes until hour 6; and every hour the participant was awake between hours 7-23)

Population: Intent to treat population of participants who took the first full dose of medication.

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.

SECONDARY outcome

Timeframe: 2 hours

Population: Intent to treat population of participants who completed the Definite Improvement Level (DIL) following study completion.

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.

SECONDARY outcome

Timeframe: 6 hours

Population: Intent to treat population of participants who completed the Definite Improvement Level (DIL) following study completion.

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.
