| Summary : Interim Analysis of Operational Futility in Randomized Trials with Time-to-Event Endpoints and Fixed Follow-Up
|
Description :
Randomized clinical trials commonly follow participants for a
time-to-event efficacy endpoint for a fixed period of time.
Consequently, at the time when the last enrolled participant completes
their follow-up, the number of observed endpoints is a random variable.
Assuming data collected through an interim timepoint, simulation-based
estimation and inferential procedures in the standard right-censored
failure time analysis framework are conducted for the distribution of
the number of endpoints--in total as well as by treatment arm--at the
end of the follow-up period. The future (i.e., yet unobserved)
enrollment, endpoint, and dropout times are generated according to
mechanisms specified in the simTrial() function in the \'seqDesign\'
package. A Bayesian model for the endpoint rate, offering the option to
specify a robust mixture prior distribution, is used for generating
future data (see the vignette for details). Inference can be restricted
to participants who received treatment according to the protocol and
are observed to be at risk for the endpoint at a specified timepoint.
Plotting functions are provided for graphical display of results.
