Trial Outcomes & Findings for Vilazodone for Treatment of Geriatric Depression (NCT NCT01608295)
NCT ID: NCT01608295
Last Updated: 2018-05-11
Results Overview
The HAMD measures the severity of depressive symptoms in participants with major depressive disorder (MDD). It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is the sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms.

Participant Flow
Single site outpatient clinic in the U.S.
208 volunteers were assessed for eligibility, of which 100 declined to participate and 37 did not meet inclusion criteria. Seventy-one persons consented to participate, of which 65 passed screening and were enrolled; nine of 65 enrolled participants withdrew before randomization.
Participant milestones
| Measure |
Vilazodone; Viibryd
After screening and baseline test results are reviewed and eligibility criteria are confirmed, medications will be dispensed if patients continue to meet eligibility criteria and sign the informed consent form. All eligible subjects will be randomized to vilazodone or paroxetine group using a computer-generated random assignment scheme, which assigned subjects in a 1:1 ratio to each group. Randomization will be done prior to subject's being assigned to the groups. Doses of the drugs will be adjusted according to individual tolerability and safety.
Vilazodone; Viibryd: Subjects randomized to receive vilazodone blindly will have incremental dose titration of 10mg per day for the 1st week; 20mg per day the 2nd week; 40mg per day for the 3rd-12th week. Doses of the drugs will be adjusted according to individual tolerability and safety.

Paroxetine; Paxil: Subjects randomized to receive paroxetine blindly will have incremental dose titration of paroxetine 10mg per day for the 1st week; 20mg per day for the 2nd week; and 30mg per day for the 3rd-12 week. Doses of the drugs will be adjusted according to individual tolerability and safety.

SECONDARY outcome
Timeframe: Baseline and Final VisitThe The Rey-Osterrieth Complex Figure Test (REY-O) is a neuropsychological assessment in which measures visual perception and long-term visual memory. Total raw scores range from 0 to 36 with higher scores representing better outcomes in recall. The total raw score represents a sum of subscales scored by 18 individual elements which are scored for both distortion and placement. Two points are awarded to elements that are accurately drawn and properly placed, one point is given to distorted or misplaced elements, 0.5 points are given if an element is both distorted and misplaced, and missing or unrecognizable elements receive zero points.

SECONDARY outcome
Timeframe: Baseline and Final VisitPopulation: The Arms/Groups are not combined, but results are presented as a ratio of Vilazodone/Paroxetine.
Gene expression data were quantile-normalized and log2-transformed in RNA expression units. The measure included the promoter transcription factor binding motif prevalence ratio of the unit (log2 Vilazodone/Paroxetine) and ranging from a minimum of -3 to a maximum of 3 with higher scores indicating better outcomes.
