In this QCast episode, Jullia and Tom discuss efficacy endpoints in oncology clinical trials and why endpoint choice shapes how treatment benefit is assessed. They look at overall survival, progression-free survival, objective response rate, disease-free survival, event-free survival, symptom endpoints, and quality-of-life measures.

Key Takeaways

  • Overall survival remains one of the clearest measures of patient benefit, but it can require longer, larger trials and may be affected by treatments given after the study therapy.
  • Progression-free survival and objective response rate can show treatment activity earlier, but they answer different questions from overall survival.
  • Scan timing, missed assessments, censoring decisions, symptom questionnaires, and quality-of-life completion rates can all affect endpoint interpretation.
