Trial Outcomes & Findings for Ibuprofen Sodium Tension Headache Study (NCT NCT01362491)

NCT ID: NCT01362491

Last Updated: 2014-07-30

Results Overview

SPRID:time-weighted sum of pain relief rating combined with pain intensity difference (PRID) over 3 hours. SPRID score range:-3 (worst) to 21 (best) for SPRID 0-3. PRID: sum of pain intensity differences (PID) and pain relief rating(PRR) at each time point. PRID score range: -1=worst to 7=best. PID: baseline pain severity score minus pain severity score at a given time point (score range 0=none to 3=severe; baseline score range 2=moderately severe to 3=severe). Total score range for PID: -1(worst) to 3 (best). PRR:assessed on 5-point pain relief rating scale (0=No relief to 4=Complete relief).

PRIMARY outcome

Timeframe: 0 to 3 hours

Population: ITT population included all randomized participants who received study medication and provided a baseline assessment.

Participants evaluated the time to meaningful relief by stopping a second stopwatch labeled 'meaningful relief' at the moment the participant first began to experience meaningful relief. It was also considered achieved if the participant stated "meaningful relief" at the time the first stopwatch was depressed. Stopwatch was active up to 3 hours after dosing or until stopped by the participant, or rescue medication was administered.

Timeframe: 0 to 3 hours

Population: ITT population included all randomized participants who received study medication and provided a baseline assessment.

Participants evaluated the time to first perceptible relief by stopping a stopwatch labeled 'first perceptible relief' at the moment the participant first began to experience any relief. Stopwatch was active up to 3 hours after dosing or until stopped by the participant, or rescue medication was administered. First perceptible relief was considered confirmed by meaningful relief if the participant achieved both "first perceptible" and "meaningful" relief by either depressing the second stopwatch or by indicating that his/her "first perceptible" relief was also "meaningful".
