High Throughput Screening and Real World Biomarkers to Predict Drug-Drug and Drug-Nutrient Interactions:
Implications to polypharmacy associated with COVID treatment

Individuals with serious COVID infections often have pre-existing co-morbidities and are generally older. Thus, in addition to being prescribed drugs for the treatment of COVID19 and its sequelae, many of these individuals are taking a myriad of other drugs. In this presentation, I will describe a screening study of 25 small molecule drugs in clinical trials for COVID19 against 11 drug transporters, which are targets for clinically relevant drug-drug interactions (DDIs). Our in vitro studies revealed that 20 of the 25 drugs met the criteria suggested by FDA DDI guidances to consider a clinical DDI study. Further, I will describe the analyses of real-world transporter biomarkers in data from electronic health records, which suggested that several of the drugs actually do cause transporter-mediated DDIs clinically. I will end with a discussion of the propensity for many anti-microbial drugs to perpetrate clinical DDIs and drug-nutrient interactions, and the use of various biomarkers for predicting DDIs in pre- and post-marketing settings.
