About this study
Official title: A Pilot Study of Double-blind Comparison of Vilazodone to Paroxetine in Geriatric Depression
The purpose of this study is to examine the effects of vilazodone for the treatment of depression in older adults.
Read the detailed description
This is a 12-week double-blind comparison of a novel antidepressant, vilazodone, to the gold-standard drug, paroxetine, for the treatment of geriatric depression. We are interested in assessing the difference in response to vilazodone (VLZ) compared to paroxetine (PAR). We hope to detect difference in response in primary outcomes (depressed mood) and secondary outcomes cognition. We are seeking to examine this directly in 80 older adults (60 years of age or older) with major depression with anticipated 60 completers. This proposed trial will serve as a pilot study to estimate the efficacy and tolerability of the drug in older depressed adults, and use this project for dose-finding in this population.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Vilazodone; ViibrydDrug
Also called Vilazodone, Viibryd, Antidepressant
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; PaxilDrug
Also called Paroxetine, Paxil, Antidepressant
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.
| Study group | Role | What they receive |
|---|---|---|
| Vilazodone; Viibryd | Experimental | 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. Receives: Drug: Vilazodone; Viibryd |

What is being measured
The primary outcome is the main question the study is designed to answer.
Hamilton Depression Rating Scale (HDRS)
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.
Measured: Baseline and 12 weeks
Secondary outcomes (3)
UKU Side-effect Profile
Number of participants with each side-effect event.
Measured: Each visit for 12 weeks
Neurocognitive Measure: The Rey-Osterrieth Complex Figure Test
The 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.
Measured: Baseline and Final Visit
Changes in Proinflammatory Gene Expression From Baseline to Final Visit (up to 12 Weeks)
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.
Measured: Baseline and Final Visit
