Trial Outcomes & Findings for PRIME Care (PRecision Medicine In MEntal Health Care) (NCT NCT03170362)

NCT ID: NCT03170362

Last Updated: 2024-05-28

Results Overview

The investigators will use the Patient Health Questionnaire 9 (PHQ9) as a self assessed marker of depression remission. The scale ranges from 0 to 27 with lower scores indicating less depression severity. Remission was defined as a score of 5 or less at the endpoint. the reported number of participants are those reaching that threshold of symptoms.

Measure
Intervention Group
Pharmacogenetic test results will be provided to the provider within 72 hours of randomization in order to facilitate choice in selecting antidepressants. Pharmacogenetic Test: The intervention is a battery of pharmacogenetic test results that mostly affect the metabolism of antidepressants and other medications.
Delay Results Group
The comparator arm will not receive results at the time of randomization but will get results after the 24 week assessment (thus the results are delayed).

PRIMARY outcome

Timeframe: Over the first 30 days

The investigators will examine the proportion of antidepressants prescribed in the first 30 days of the trial that have the potential for gene-drug interactions. The chance for a gene-drug interaction was classified as 1. the subject did not have a prescription for an antidepressant during the initial 4 weeks of the trial (No Antidepressant), 2 the subject was prescribed an antidepressant with no known gene-drug interaction (No Gene Interaction), 3 the subject was prescribed an antidepressant with moderate gene-drug interactions (Moderate Interaction). These are also gene-drug interactions that do not have level A concordance. And 4. the subject was prescribed an antidepressant with substantial gene-drug interactions or gene-drug interactions that are considered to have a high level of evidence to support other prescribing.

SECONDARY outcome

Timeframe: 24 Weeks

The investigators will use the Patient Health Questionnaire 9 (PHQ9) as a self-assessed marker of depression remission. The scale ranges from 0 to 27 with lower scores indicating less depression severity. This measure will use the PHQ9 as a continuous measure. The reported outcome is the difference in scores from baseline to 24 weeks.

SECONDARY outcome

Timeframe: 24 weeks

The investigators will use the Patient Health Questionnaire 9 (PHQ9) as a self assessed marker of depression remission. The scale ranges from 0 to 27 with lower scores indicating less depression severity. Response was measured by a 50% reduction in scores from baseline to each time point.
