Trial Outcomes & Findings for A Safety And Efficacy Study of Ibuprofen 250 mg / Acetaminophen 500 mg In The Treatment Of Post-Surgical Dental Pain (NCT NCT02912650)

NCT ID: NCT02912650

Last Updated: 2017-08-30

Results Overview

Pain intensity was assessed on an 11-point numerical pain severity rating scale. SPID11 (0-8): Time-weighted sum of pain intensity difference (PID) scores over 8 hours. SPID11 score range was -40 (worst score) to 80 (best score) for SPID 0-8. PID was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 =no pain to 10 =worst possible pain) from the baseline pain intensity scores (score range: 5 =moderate pain to 10 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID: -5 (worst score) to 10 (best score).

Timeframe: 0 to 12 hours post-dose

Population: FAS included all randomized participants who were dosed with the study medication and provided a baseline assessment. Here, "number of participants analyzed" signifies those participants who had the event (meaningful pain relief).

Participants evaluated time to meaningful relief by stopping a second stopwatch labelled as "meaningful relief" at the moment they first began to experience meaningful relief. Stopwatch was active up to 12 hours after dosing or until stopped by participant, or participant became treatment failure prior to depressing the second stopwatch. Treatment failure was defined as participant taking rescue medication, or discontinuing due to lack of efficacy.

Participants evaluated the time to first perceptible relief (confirmed by meaningful relief) by stopping the first stopwatch labeled 'first perceptible relief' at the moment they first began to experience any pain relief, if the participant also achieved meaningful relief by the end of the study. Stopwatch was active up to 12 hours after dosing or until stopped by the participant, or until the participant dropped out due to treatment failure prior to depressing the first stopwatch or until the time of withdrawal (discontinuation). Treatment failure was defined as participant taking rescue medication, or discontinuing due to lack of efficacy.

Timeframe: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

Population: FAS included all randomized participants who were dosed with the study medication and provided a baseline assessment.

PID11: baseline pain severity score minus pain severity score at a given time point. Pain intensity was assessed on an 11-point numerical pain severity rating scale. PID11 was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 =no pain to 10 =worst possible pain) from the baseline pain intensity scores (score range: 5 =moderate pain to 10 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID11: -5 (worst score) to 10 (best score).

Timeframe: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

Population: FAS included all randomized participants who were dosed with the study medication and provided a baseline assessment.

PID4: baseline pain severity score minus pain severity score at a given time point. Pain intensity was assessed on a 4-point categorical pain severity rating scale. PID4 was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 \[no pain\] to 3 \[worst possible pain\]) from the baseline pain intensity scores (score range: 2 =moderate pain to 3 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID4: -1 (worst score) to 3 (best score).

Timeframe: 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

Population: FAS included all randomized participants who were dosed with the study medication and provided a baseline assessment.

Treatment failure was defined as taking the rescue medication or discontinuation of the participants from the study due to lack of efficacy, whichever came first. Participants were censored at 12 hours or at their final assessment time, whichever came first. Percentage of participants who had treatment failure were reported.

Timeframe: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

Population: FAS included all randomized participants who were dosed with the study medication and provided a baseline assessment.

Percentage of participants with confirmed first perceptible relief was reported. Participants evaluated the time to first perceptible relief (confirmed by meaningful relief) by stopping the first stopwatch labelled 'first perceptible relief' at the moment they first began to experience any pain relief, if the participant also achieved meaningful relief by the end of the study. Stopwatch was active up to 12 hours after dosing or until stopped by the participant, or until the participant dropped out due to treatment failure prior to depressing the first stopwatch or until the time of withdrawal (discontinuation). Treatment failure was defined as participant taking rescue medication, or discontinuing due to lack of efficacy.

Stopwatch was active up to 12 hours after dosing or until stopped by participant, or participant became treatment failure prior to depressing the second stopwatch.
