This article introduces CoDHy, an AI system designed to function as a co-scientist for generating and validating drug combination hypotheses in oncology using biomarker data. By integrating knowledge graphs with agent-based reasoning, the tool allows researchers to iteratively refine evidence-grounded hypotheses while maintaining control over prioritization. This represents a significant advancement in applying machine learning agents to accelerate translational research workflows.

From Literature to Hypotheses: An AI Co-Scientist System for Biomarker-Guided Drug Combination Hypothesis Generation

arXiv2 min read

arXiv:2603.00612v2 Announce Type: replace Abstract: The rapid growth of biomedical evidence makes it difficult to translate biomarker mechanisms into actionable drug combination hypotheses. We present CoDHy, an interactive AI co-scientist for biomarker-guided hypothesis generation in oncology. CoDHy constructs task-specific knowledge graphs from curated databases and biomedical literature, then combines graph embeddings with agent-based reasoning to generate, validate, and rank evidence-grounded drug combinations. Through a web interface, researchers specify the biomarker, cancer context, and literature scope; inspect supporting evidence and intermediate results; and iteratively refine the generated hypotheses. The demonstration presents CoDHy's end-to-end workflow and shows how researchers can interactively explore and compare mechanistically supported drug combinations while remaining in control of hypothesis prioritization.
