Mechanistic Target Engagement

Mechanistic target engagement confirms pharmaceutical binding to intended molecular target validating mechanism-of-action. Biochemical binding assays quantitate target interaction. Cell-based target engagement uses cellular readouts. Biomarker assessment detects downstream pathway activation. Dose-dependent engagement characterises dose-response relationship.

Regulatory submissions employ engagement evidence supporting efficacy. Clinical outcomes correlate with target engagement. Resistance mechanisms from reduced engagement warrant investigation. Post-approval monitoring confirms sustained engagement. Emerging imaging enables visualised target engagement.
