Description

This guidance provides FDA's current thinking on use of baysian statistics in medical device clinical trials.

Scope & Applicability

Product Classes

2
Medical Device

FDA intends to assess device cybersecurity based on a number of factors; demonstrate or maintain its safety and effectiveness; ensuring cybersecurity has become essential to FDA’s ability to protect the public health; Cyber-resiliency capabilities for medical devices

Coronary artery stent

specific device type mentioned in historical control methods

Stakeholders

6
FDA Advisory Panel

A body that may question the prior information used in a Bayesian analysis.; members who must agree with opinions used to generate priors

Sponsor

Entity responsible for submitting applications under section 524B

FDA reviewers

Agency staff who do not review sample submissions

Statistician

Consulted by lead reviewer for checklist completion

Engineer

Engineers should be satisfied that design or manufacturing differences do not alter performance

Clinician

Provides clinical judgment and conducts assessments for ClinROs.

Regulatory Context

Attributes

10
Sample Size

statistically justified calculation required in the plan

Effective Sample Size

summary computed to quantify efficiency gained from prior information

Credible intervals

FDA strongly encourages reporting of credible intervals for Bayesian trials in the labeling.

Power

A parameter required for sample size calculation.

Type II error rate

probability of erroneously disapproving a safe and effective device

Type I error rate

Statistical parameter requiring strong control when testing multiple endpoints

Covariates

demographic and prognostic variables used for statistical adjustments

Effectiveness

Evidence of benefit from everyday medical practice.

Safety

characterizing the safety of individual drugs

Endpoints

Measures of safety and effectiveness used to support a certain claim
