To evolve AI from pattern matching to understanding physics for protein engineering, structural data is insufficient. Models need physical parameters like Gibbs free energy (delta-G), obtainable from affinity measurements, to become truly predictive and transformative for therapeutic development.

The company focuses on disease-specific 3D protein conformations, which exposes new binding sites (epitopes) not present on the same protein in healthy cells. This allows for highly selective drugs that avoid the toxicity common with targets defined by genetic sequence alone.

The discovery-based model of finding highly impactful single targets like HER2 or PD-1 is becoming unsustainable as the low-hanging fruit is picked. The field must shift toward an engineering-first approach, designing complex, multi-functional therapeutics to achieve specific clinical objectives, much like high-tech fields.

To overcome on-target, off-tumor toxicity, LabGenius designs antibodies that act like biological computers. These molecules "sample" the density of target receptors on a cell's surface and are engineered to activate and kill only when a specific threshold is met, distinguishing high-expression cancer cells from low-expression healthy cells.

Increasing a biologic's binders from two or four to six or twelve is not an incremental improvement. It creates 'emergent properties of scale.' This high valency allows for sophisticated control over 3D spatial geometry at the cell surface and eliminates the design trade-offs inherent in simpler multispecific molecules.

A-muto suggests many drug programs fail due to toxicity from hitting the wrong epitope, not a flawed biological concept. By identifying and targeting a structural epitope unique to the diseased state of the same protein, these previously abandoned but promising therapies could be salvaged.

As biologics evolve into complex multi-specific and hybrid formats, the number of design parameters (valency, linkers, geometry) becomes too vast for experimental testing. AI and computational design are becoming essential not to replace scientists, but to judiciously sample the enormous design space and guide engineering efforts.

For complex biologics with many binders, chasing astronomical affinity is counterproductive and risks off-tumor toxicity. A better strategy is to use binders with modest affinity and leverage the massive avidity gained from multiple binding sites. This provides a 'finer dial' to tune specificity and improve the therapeutic window.

Current tools excel at the static binding problem. To advance to creating true therapeutics, models must incorporate the physics of displacing solvent and ions from an interface—currently neglected but one of the "biggest enemies" of strong binding in a physiological context.
