Summary OBJECTIVE: The objective of this study is to investigate the influence of the 5-HTTLPR (serotonin transporter-linked promoter region), cytochrome P450 2C19, and cytochrome P450 2D6 polymorphisms on escitalopram (ESC) and venlafaxine (VEN) responses in major depressive disorder.

METHOD: A prospective multi-site study of 106 patients (Caucasian and Han Chinese ethnicities) with major depressive disorder treated with either ESC or VEN was conducted. The 17-item Hamilton Depression scale (HDRS), Clinical Global Impression Scale, and an adverse events scale (UKU) were assessed over 8 weeks, blind to genotype.

RESULTS: At the 8-week end point, a significant HDRS reduction for both ESC and VEN occurred (p < 0.0001). The 5-HTTLPR l/l genotype was associated with significantly greater score reductions on the HDRS compared with s/s carriers (p = 0.016) among Caucasian subjects receiving ESC (n = 47). Response rates were significantly higher for l/l (92%) compared with l/s (61%) and s/s (46%) variants (p = 0.042). For every l allele a participant carried, there was a 3.33 (95% confidence interval 1.25, 8.84; p = 0.02) times greater odds of ESC response. No significant associations between any of the genotypes and adverse effects were found.

CONCLUSION: Ethnicity may have differential effects on the 5-HTTLPR genotype-efficacy relationship. Results suggest that l/l allele for 5-HTTLPR is associated with a robust treatment response to ESC in Caucasian subjects only.
