Prospective observational study (n=85 actual) collecting saliva genetic samples from adults who previously received IV ketamine for treatment-resistant depression to correlate genetic biomarkers with treatment response.
Participants who previously received intravenous ketamine for treatment-resistant depression provide two saliva swabs for genetic analysis; the study examines associations between genetic markers and clinical response to IV ketamine.
Observational, prospective design leveraging clinic-treated patients at the Canadian Rapid Treatment Centre of Excellence; outcomes are biomarker–response correlations rather than interventional efficacy.
Participants who previously received IV ketamine provide saliva for genetic analysis to correlate biomarkers with treatment response.
Saliva genetic samples: two saliva swabs collected; genetic analysis only.
