Trial Outcomes & Findings for Deplin® P.L.U.S. Program (Progress Through Learning Understanding & Support) (NCT NCT01369030)

NCT ID: NCT01369030

Last Updated: 2014-06-03

Results Overview

The PHQ-9 is a depression scale used to assess brief depression severity by rating symptoms and functional impairment experienced in the last two weeks. The questionnaire contains a total of 9 questions, and each question is scored on a range from 0-3. The minimum value "0" represents not at all, "1" several days, "2" indicates more than half the days, and the maximum value "3" stands for nearly every day. The total possible range is 0-27. The total number of each 0, 1, 2, 3 is added and multiplied by its value (0=0, 1=1, etc.) to produce a total score generated from the subtotal sum. The PHQ-9 total score is interpreted as follows: 0-4 represents minimal depression, 5-9 as mild depression, 10-14 as moderate depression, 15-19 moderately severe depression, and 20-27 severe depression.

Participant Flow

Between November 2010 and January 2012, patients of at least 18 years of age who had been prescribed Deplin® by their physician for the treatment of major depression were offered to participate in the study by their prescibing physician, consisting of about 550 participating physicians located at various clinical sites country-wide.

Participants may have excluded themselves from the overall study after self-enrolling in the program if they did not complete the designated surveys prior to using Deplin® (Baseline) or at the 90-day time point post-treatment initiation.

PRIMARY outcome

Timeframe: Baseline to Endpoint (90 days)

Population: Analyses were performed on the 554 patients who had a baseline PHQ-9\>=5 and further analyzed by baseline depression severity groups defined by baseline PHQ-9 scores: 5\<=PHQ-9\<=9; 10\<=PHQ-9\<=14; 15\<=PHQ-9\<=19; and 20\<=PHQ-9\<=27.
