Trial Outcomes & Findings for Study to Assess the Effectiveness and Safety of FLECTOR Patch for Treatment of Acute Back Strain (NCT NCT01054820)

NCT ID: NCT01054820

Last Updated: 2012-08-16

Results Overview

Participant-rated instrument to assess functional activities (general activity, mood, walking ability, relations with other people, sleep, normal work, and enjoyment of life) in past 24 hours. Question 5: Please rate your pain by marking the box beside the number that best describes your pain on the average (over the last 24 hours); rated on an 11 point Likert rating scale ranging from 0 (no pain) to 10 (pain as bad as you can imagine).

PRIMARY outcome

Timeframe: Baseline, End of Treatment (last visit up to Day 15)

Population: Intent to Treat (ITT) population: had at least one application of FLECTOR® Patch, pain survey data at Baseline, and at least 1 follow-up visit. EOT score calculated by taking average of any non-missing scores recorded last 3 days of treatment; if no score on those days, EOT was single, most recent non-missing score recorded on a treatment day.

Participant-rated instrument to assess functional activities (general activity, mood, walking ability, relations with other people, sleep, normal work, and enjoyment of life) in past 24 hours. Question 5: Please rate your pain by marking the box beside the number that best describes your pain on the average (over the last 24 hours); rated on an 11 point Likert rating scale ranging from 0 (no pain) to 10 (pain as bad as you can imagine).

SECONDARY outcome

Timeframe: Baseline, End of Treatment (last visit up to Day 15)

Population: ITT population; End-of-Treatment score was the most recent non-missing value.

The Beck Depression Inventory® II consisted of 21 items, each with 4 categorical responses ranging from 0 (I do not feel sad) to 3 (I am so sad or unhappy that I can't stand it) with maximum possible score of 63; increase in the number reflected an increase in severity. Total Beck Depression Inventory® II scores classified as follows: 1 to 10=normal ups and downs; 11 to 16=mild mood disturbance; 17 to 20=borderline clinical depression; 21 to 30=moderate depression; 31 to 40=severe depression; and \>40=extreme depression.
