February 4, 2021 | A computer scientist at The Ohio State University (OSU) recently demonstrated the potential of artificial intelligence to crunch real-world data and emulate randomized clinical trials, speeding the pace of drug repurposing. The initial use case was focused on preventing heart failure and stroke in patients with coronary artery disease, but the model could be applied to any disease with a definable outcome, says Ping Zhang, who leads the Artificial Intelligence in Medicine Lab at OSU.
Zhang is senior author of a recently published study in
Nature Machine Intelligence (DOI: 10.1038/s42256-020-00276-w) where a deep learning algorithm ingested insurance claims on nearly 1.2 million deidentified patients to identify existing medications with a heretofore unknown therapeutic effect on coronary artery disease (CAD; e.g., diabetes drug metformin and antidepressant escitalopram, both of which were already being tested

A new phenotype-based compound screening technology, called DeepCE, identified 10 compounds that could be repurposed for COVID-19.
DeepCE (pronounced ‘Deep Sea’), a novel deep-learning computer model that can predict how gene expression will change in response to medicines, has been used to identify 10 compounds that could be repurposed as treatments for COVID-19.
Two of the drugs – cyclosporin, an immunosuppressant used to prevent transplant organ rejection, and anidulafungin, an antifungal agent – are currently approved for clinical use. The others are investigational and being evaluated in a wide range of indications, from hepatitis C and fungal disease to cancer and heart disease. According to the team, some of these candidates have already been evaluated in COVID-19 patients.

COLUMBUS, Ohio - A new deep-learning model that can predict how human genes and medicines will interact has identified at least 10 compounds that may hold promise as treatments for COVID-19.
All but two of the drugs are still considered investigational and are being tested for effectiveness against hepatitis C, fungal disease, cancer and heart disease. The list also includes the approved drugs cyclosporine, an immunosuppressant that prevents transplant organ rejection, and anidulafungin, an antifungal agent.
The discovery was made by computer scientists, meaning much more work needs to be done before any of these medications would be confirmed as safe and effective treatments for people infected with SARS-CoV-2. But by using artificial intelligence to arrive at these options, the scientists have saved pharmaceutical and clinical researchers the time and money it would take to search for potential COVID-19 drugs on a piecemeal basis.
