The study performs statistical analysis of drug–disease–gene interactions and builds a general processing pipeline with machine learning models to predict cancer-cell drug sensitivity from genetic mutations. Four open-source datasets (drug sensitivity, somatic mutations, and gene–drug interactions) are integrated into an enriched database with preprocessing for text encoding, filtering, and optimization, followed by interaction testing, contribution quantification, ablation, and feature-importance analyses; results show strong generalizability with high R2 values across independent sources.","Received 12 January 2026, accepted 25 January 2026, date of publication 29 January 2026, date of current version 5 February 2026.

Particularly, cancerous tissues undergo constant change as a result of ongoing mutations, and the sensitivity of drugs to cancer may change as a result of new mutations. For this purpose, this study aims to present a statistical analysis of drug–disease– gene interactions. Furthermore, a general processing pipeline and machine learning models were developed to predict the drug sensitivity of cancer cells according to genetic mutations. To achieve this, four well-known open-source databases, including drug sensitivity data from cancer cell lines, two somatic mutation data resources, and a gene-drug interaction database, were integrated to assess an enriched database. Next, various preprocessing techniques, including text encoding, filtering, and optimization, were implemented to attain an efficient new dataset for statistical analysis and machine learning. Statistical analyses were conducted to investigate gene–drug interactions on the enriched database and to quantify their relative contributions to drug sensitivity. On the other hand, developed machine learning models predict drug sensitivity from somatic mutation or drug interaction datasets. The research also includes ablation studies and feature importance to introduce a thorough analysis of gene and drug sensitivity. The developed pipeline not only yielded an R2 of 0 .91 in initial evaluations but also demonstrated robust generalizability by maintaining a 0 .73 R2 score in predicting AUC values across independent data sources. Overall, statistical analysis, machine learning performances, and ablation studies offer a new perspective on drug sensitivity prediction.  \nINDEX TERMS Drug sensitivity, prediction of Z-score by machine learning, integration of multiple data resources, data manipulation, machine learning models.  \nI. INTRODUCTION  \nRapid advancements in molecular biology, genomics, and computational technologies over the past thirty years have laid the foundation for major progress in pharmacological research. The integration of these fields has particularly accelerated developments in drug discovery and drug repurposing.

Furthermore, drug repurposing aims to reduce the costs, time, and effort associated with drug development by bypassing early-stage processes such as discovery, preclinical testing, and production preparation [6] . For example, drugs such as Minoxidil, Thalidomide, and Sildenafil, which were previously used to treat different conditions, have been repurposed and are now used to treat different diseases [4],[7],[8] .  \nWhen we delve deeper into the topic of drug repurposing, we inevitably encounter the concepts of drug resistance and drug sensitivity.
