InterAx Biotech
InterAx Biotech is a spin-off from ETH Zurich and the Paul Scherrer Institute, Switzerland. The company specializes in G Protein-Coupled Receptor (GPCR) drug discovery and is recognized as the world leader in quantitative mechanistic understanding of GPCR drug action. InterAx developed a new mathematical modelling approach that resolves the biological mechanisms of drug effects at the cell signalling level – thereby addressing a crucial gap in conventional drug discovery. The vast majority (90%) of drug candidates fail in clinical development, and 50% of the failures are due to the lack of drug efficacy in humans. This highlights the insufficient understanding of the biology of drug effects. Coinciding with this apparent knowledge gap, many pre-clinical programs omit detailed characterisation of cell-level responses, and proceed rapidly from molecular to ADMET and organism-level studies.
InterAx has built an integrated preclinical drug discovery platform around its unique mathematical models of GPCR cell signalling. The platform covers target characterization, hit identification, hit-to-lead and lead optimization stages. The platform combines state-of-the-art time-resolved biology assays, high throughput compound screening, computational systems biology, advanced molecular dynamics, machine learning / AI pipelines, and a full range of computational chemistry and medicinal chemistry approaches. This „mechanistic biology“-centred platform unlocks previously intractable and high-risk-of-failure targets. It was validated in several industry collaborations and is already yielding drug candidates with novel modes of action in oncology and metabolic disease areas. For example, the company has identified important cell signalling properties correlated with side effects in orally available diabetes treatments and is rationally designing new generation of drugs to replace injectable treatments in a $50-billion dollar market.
Given this company’s vital expertise in molecular dynamics, mathematical models of GPCR drug action and machine learning / AI approaches for drug characterization and design, InterAx is highly motivated by the UniSens technology concept and its potential to deliver better drugs faster.
