Trial Outcomes & Findings for Vilazodone for Corticosteroid-Induced Memory Impairment (NCT NCT01828515)

NCT ID: NCT01828515

Last Updated: 2019-04-11

Results Overview

The Rey Auditory Verbal Learning Test (RAVLT) measures verbal or declarative learning and memory. The test consists of 15 nouns read aloud for five consecutive trials with each trial followed by a free-recall trial. Following the fifth trial, an interference list of 15 different words is presented followed by a free-recall trial of that list. Delayed recall of the first list is tested immediately following the interference list and after a 20-minute delay. Equivalent, alternative versions (different words) were used to minimize practice or learning effects from repeated administration. The raw scores (number of words correct across trials 1-5) are converted to standardized T-scores (M=50; SD=10). This score is used to determine the participant's performance in relation to norm-referenced expectations based on age and sex. Higher score reflects better performance, and the values reflect scores at baseline minus the scores at Day 19.

Measure
Vilazodone and Hydrocortisone,Then Placebo and Hydrocortisone
Vilazodone was initiated at 10 mg/day for 7 days and increased to 20 mg/day for 7 days. After that time an additional increase to 40 mg/day for 5 days (totaling 19 days). On the 2nd day of the 40 mg a day portion, 160 mg of hydrocortisone/day was given for 4 days. After a washout period of 23 days, placebo was given for 19 days and hydrocortisone was given for 4 days.
Placebo and Hydrocortisone, Then Vilazodone and Hydrocortisone
Placebo was given for 19 days and hydrocortisone was given for 4 days. After a washout period of 23 days, Vilazodone was initiated at 10 mg/day for 7 days and increased to 20 mg/day for 7 days. After that time an additional increase to 40 mg/day for 5 days (totaling 19 days). On the 2nd day of the 40 mg a day portion, 160 mg of hydrocortisone/day was given for 4 days.
