Trial Outcomes & Findings for Study of 6(S)-5-MTHF Among Selective Serotonin Reuptake Inhibitor-Resistant Outpatients With Major Depressive Disorder (NCT NCT00955955)

NCT ID: NCT00955955

Last Updated: 2017-04-28

Results Overview

The HAM-D-17 is a multiple choice questionnaire that clinicians may use to rate the severity of a patient's major depression. Items are scored on a scale of zero to four and higher scores indicate greater impairment. This scale is scored by summing the scores on each item and scores can range from 0-68. When assessing changes in HAMD score, negative changes indicate improvement (i.e. the score has decreased) and positive scores indicate a worsening of symptoms (i.e. scores have increased).

PRIMARY outcome

Timeframe: Baseline and Day 60

Population: The phase II dataset of interest is limited to patients treated with placebo in phase I, completed phase I, did not experience a clinical response and entered phase II. Drug is compared to placebo in phase II for this subset alone. Some patients received Deplin in both phases of the study, but those patients are not included in these analyses.

SECONDARY outcome

Timeframe: Baseline and Day 60

Population: Data presented is mean score reduction for the QIDS. The dataset of interest is limited to patients treated with placebo in phase I, did not experience a clinical response and entered phase II. Drug is compared to placebo in phase II for this subset alone.

This measure is a 16 item self report questionnaire assessing symptoms of depression. For each item, scores range from 0 to 3 with higher scores indicating greater impairment. To score this measure: 1. Enter the highest score from questions 1-4 (sleep items): \_\_\_\_\_\_ 2. Enter score on item 5 \_\_\_\_ 3. Enter the highest score from questions 6-9 (appetite/weight): \_\_\_\_\_\_ 4. Enter score on item 10 \_\_\_\_ 5. Enter score on item 11 \_\_\_\_ 6. Enter score on item 12 \_\_\_\_ 7. Enter score on item 13 \_\_\_\_ 8. Enter score on item 14 \_\_\_\_ 9. Enter the highest score from questions 15-16 (psychomotor items): \_\_\_\_\_\_ Total score range 0-27: \_\_\_\_\_\_ When assessing changes in this measure over time, negative means indicate an improvement (i.e. the scores decreased over time) and positive means indicate worsening in functioning.
