CALMA, a novel computational framework, revolutionizes drug combination design by integrating genome-scale metabolic modeling with an artificial neural network. It significantly reduces experimental burden and enhances interpretability, paving the way for safer and more effective antimicrobial treatments.
CALMA's methodology involves three key steps: simulating metabolic reaction fluxes using GEMs, constructing joint profile features from this data, and employing an ANN to predict drug combination potency and toxicity. Its unique architecture, inspired by metabolic subsystems, drastically reduces model parameters and improves generalizability.
CALMA achieved significant accuracy in predicting drug combination potency and toxicity across various datasets. It identified crucial metabolic pathways, such as nucleotide salvage, influencing toxicity, a finding validated through in vitro experiments and real-world health record analysis showing reduced nephrotoxicity for specific combinations.
