Atezolizumab (a PD-L1 inhibitor) has shown remarkable efficacy and tolerability in various cancer types.Despite its efficacy and safety, atezolizumab monotherapy has limitations, such as acquired resistance and adverse events.Bojungikki-tang (BJIKT) is an herbal decoction widely prescribed in Asian countries and used to treat cancer-related symptoms including fatigue, appetite loss, gastrointestinal disorders, and Bedframe other side effects from cancer therapy.Due to its immunomodulatory effects, Bojungikki-tang has been investigated as a combined treatment with anticancer agents.We evaluated the potential drug-drug interaction (DDI) between Bojungikki-tang and the anti-PD-L1 antibody based on the Food and Drug Administration (FDA) guidelines.

In the study, we conducted an in vivo drug-drug interaction study using a syngeneic mouse model of CMT-167 in C57BL/6.We then determined the antibody concentrations to evaluate the pharmacokinetic (PK) drug-drug interaction and measured variable biomarkers related to therapeutic efficacy and immune response.The pharmacodynamic (PD) drug-drug interaction study investigated changes in response between anti-PD-L1 antibody monotherapy and combination therapy.Using the pharmacokinetic and pharmacodynamic data, we conducted a statistical analysis to Stove Seal Clip assess drug-drug interaction potential.In the presence of Bojungikki-tang, the pharmacokinetic characteristics of the anti-PD-L1 antibody were not changed.

This study suggested that combination treatment with Bojungikki-tang and atezolizumab is a safe treatment option for non-small cell lung cancer.Clinical studies are warranted to confirm this finding.
