Area of Science:

  • Biostatistics
  • Clinical Trials
  • Epidemiology

Background:

  • Cure rate estimation is crucial in pediatric clinical trials.
  • The modified Gompertz hazard function (Cantor and Shuster) is a tool for cure rate estimation.
  • Incorporating covariate effects can refine cure rate models.

Purpose of the Study:

  • To extend the modified Gompertz hazard function by incorporating covariate effects.
  • To provide a flexible method for estimating cure rates as a function of treatments and covariates.
  • To enhance the analysis of pediatric clinical trial data.

Main Methods:

  • Extension of the modified Gompertz hazard function.
  • Inclusion of covariate effects into the hazard function.
  • Application to pediatric clinical trial data for cure rate estimation.
