IDgenetix-Guided Medication Management for Major Depressive Disorder: Confirmation of Randomized Controlled Trial Outcomes by Real-World Evidence
Year: 2024
Type: article
Abstract: Introduction IDgenetix is an advanced multi-gene pharmacogenomic (PGx) test that incorporates drug-gene interactions, drug-drug interactions, and lifestyle factors to guide medication management for patients diagnosed with major depressive disorder (MDD), anxiety, or other mental illnesses. In a previously published randomized controlled trial (RCT), IDgenetix significantly improved patient response and remission rates (Bradley et al., 2018). In this analysis, we aimed to compare the clinical outcome results from the RCT with real-world evidence from an open-label study (Cao et al., 2023). Methods Subjects with moderate to severe MDD at baseline per their HAM-D17 or PHQ-9 scores were included in the analysis for the RCT (n=261) and real-world data (n=242). In both studies, 8-week response and remission rates were analyzed for patients using IDgenetix-guided medication management (Guided) compared to patients receiving standard of care (Unguided). Results Patient response and remission rates strongly aligned between both studies. Response rates for the IDgenetix-guided participants in the RCT were 49% compared to 58% in the real-world data. Remission rates in the Guided group were 31% in both the RCT and real-world study compared to 22% and 19%, respectively, for participants in the Unguided group. Conclusions Comparing the clinical outcome results from the RCT with real-world data demonstrated the consistent impact of IDgenetix on patient response and remission rates. This study provides robust evidence-based research that supports the clinical use of IDgenetix to guide medication management in patients with MDD. Funding Castle Biosciences (Friendswood, TX)
