The development of a new diagnostic test ideally follows a sequence of stages which, among other aims, evaluate technical performance. This includes an analytical validity study, a diagnostic accuracy study, and an interventional clinical utility study. In this article, we propose a novel Bayesian approach to sample size determination for the diagnostic accuracy study, which takes advantage of information available from the analytical validity stage. We utilize assurance to calculate the…

A Review of Bayesian Perspectives on Sample Size Derivation for Confirmatory Trials

Abstract Sample size derivation is a crucial element of planning any confirmatory trial. The required sample size is typically derived based on constraints on the maximal acceptable Type I error rate

How to Ease the Pain of Taking a Diagnostic Point of Care Test to the Market: A Framework for Evidence Development

A framework for developing the evidence needed to support product development, marketing, and adoption is proposed and device manufacturers are helped to understand the concepts and terminology used in evaluation of in vitro diagnostics so that they can communicate effectively with evaluation methodologists, statisticians, and health economists.

A comparison of prior elicitation aggregation using the classical method and SHELF

This paper compares aggregated priors formed by Equal Weight Aggregation, the Classical Method, and the Sheffield Elicitation Framework to each other and individual expert priors, using an expert elicitation carried out for a clinical trial.

Optimal Decision Criteria for the Study Design and Sample Size of a Biomarker-Driven Phase III Trial.

The design and sample size of a biomarker-driven phase III study can be appropriately determined based on the expected net present value (eNPV), a measure of the probability of success of a study calculated based on historical data, the revenue that will be obtained after the success of the phase II study, and the cost of the study.

Targeted test evaluation: a framework for designing diagnostic accuracy studies with clear study hypotheses

This paper proposes a strategy for defining meaningful hypotheses in diagnostic accuracy studies based on the role of the index test in the clinical pathway and the downstream consequences of test results, to arrive at minimally acceptable criteria for pre-defined test performance.

Adaptive trial designs in diagnostic accuracy research

The current status of methodological research and applications of flexible designs in diagnostic accuracy research is summarized and future development of adaptive design methodology and their use in diagnostic accuracies trials are indicated and advocated from an interdisciplinary viewpoint.

Assurance for Sample Size Determination in Reliability Demonstration Testing

This article develops the assurance approach for sample size calculations in RDTs for binomial and Weibull likelihoods and proposes appropriate prior distributions for the design and analysis of the test.
