A Biomarker-Based Dose-Schedule Optimization Design for Immunotherapy Trials.

ABSTRACT: In immunotherapy, both the dose and the schedule of drug administration can significantly influence therapeutic effects by modulating immune system activation. Incorporating immune response measures into clinical trial designs offers an opportunity to enhance decision-making by leveraging their close association with therapeutic efficacy and toxicity. Motivated by settings where biomarker data indicate improved efficacy in biomarker-positive patients, we propose a dose-schedule optimization strategy tailored to each biomarker-defined subgroup, based on elicited utility functions that capture risk-benefit tradeoffs. We introduce a joint modeling framework that simultaneously evaluates immune response, toxicity, and efficacy, enabling information sharing across outcome types and patient subg
