Summary
This study introduces the logistic dose ranging strategy (LDRS) as a flexible alternative to the continual reassessment method (CRM) for early-phase clinical trials. LDRS utilizes logistic regression for dose selection and can incorporate covariates to optimize trial design.
Area of Science:
- Clinical Trials Methodology
- Biostatistics
- Pharmacometrics
Background:
- The continual reassessment method (CRM) is a standard approach for dose escalation in phase I trials.
- Existing methods may lack flexibility or ease of implementation.
- Accurate dose selection is critical for patient safety and trial efficiency.
Purpose of the Study:
- To introduce and evaluate the logistic dose ranging strategy (LDRS) as an alternative to CRM.
- To demonstrate the adaptability of LDRS as a standalone or integrated dose allocation scheme.
- To explore the utility of LDRS in examining covariate effects on toxicity.
Main Methods:
- The LDRS employs logistic regression modeling for dose allocation.
- It utilizes a dose-escalation scheme comparable to the CRM.
- Implementation is designed to be compatible with standard logistic regression software.
Main Results:
- LDRS offers a practical alternative to CRM for phase I dose finding.
- The strategy can be used independently or enhance existing dose-finding designs.
- LDRS facilitates the assessment of covariates like age and comorbidities on toxicity.
Conclusions:
- The logistic dose ranging strategy (LDRS) provides a viable and flexible approach for phase I clinical trials.
- Its ease of implementation and covariate analysis capabilities offer significant advantages.
- LDRS can improve the efficiency and informativeness of early-phase dose selection.
