Splicing Modulators — from MoA to advanced candidate
The program began with an unclear mechanism of action. Our team established the structural basis for splicing modulation, then built models that predicted selectivity over related splice sites — the key liability that had stalled earlier efforts.
Over multiple synthesis rounds, we ran multi-parameter optimization simultaneously addressing potency, selectivity, metabolic stability, and oral bioavailability. Each round produced fewer than 30 compounds, guided by free energy calculations and ML-predicted ADMET profiles.
The result was ATM5292: an advanced candidate with a clean selectivity profile, confirmed mechanism, and favorable PK in multiple species.
