Flexible Dose-Finding in Early-Phase Oncology Combination Studies Enabling Mid-Trial Dose Insertions to Improve Dose Recommendations

1 minute read

Published: April 2nd, 2026

Early-phase oncology combination trials often assume the optimal dose is already included in the dosing grid. When it isn’t, sponsors may face subtherapeutic or overly toxic recommendations, protocol amendments, and delays. 

This white paper explores a contour-based method for inserting new dose combinations mid-trial, helping improve dose selection while maintaining safety and regulatory transparency. 

What You’ll Learn 

  • How structured mid-trial dose insertions work  
  • Simulation results demonstrating improved dose selection  
  • Practical considerations for early-phase oncology studies  
  • How flexible dose-finding supports modern dose optimization strategies  

About the Author 

Matt George, Senior Statistician, Phastar 
Specialist in early-phase oncology trial design and co-author of the Statistics in Medicine publication introducing this contour-based dose insertion method.
