Insights

Glioblastoma (GBM) clinical trials face significant challenges, hindering therapeutic progress. A Society for Neuro-Oncology Think Tank identified key issues in trial design and eligibility criteria to improve future GBM research.

Area of Science:

  • Neuro-Oncology
  • Clinical Trial Design
  • Glioblastoma Therapeutics

Background:

  • Therapeutic advances for glioblastoma (GBM) have been stagnant for two decades.
  • Numerous Phase III glioblastoma trials have failed despite promising early-phase results.
  • This highlights critical issues in current clinical trial methodologies.

Purpose of the Study:

  • To review literature and identify challenges in glioblastoma clinical trial conduct.
  • To provide recommendations for improving glioblastoma clinical trial design and eligibility criteria.
  • To analyze current glioblastoma clinical trial designs for data-driven insights.

Main Methods:

  • Literature review on glioblastoma clinical trials.
  • Analysis of clinical trial design features from ClinicalTrials.gov (recruiting/not yet recruiting as of Feb 2021).
  • Expert consensus from a Society for Neuro-Oncology Think Tank meeting.

Main Results:

  • Identified significant challenges in glioblastoma trial eligibility criteria.
  • Highlighted limitations in current glioblastoma clinical trial designs.
  • Provided a data-driven overview of ongoing adult glioblastoma trials.

Conclusions:

  • Recommendations are proposed to enhance the rigor and success rate of future glioblastoma clinical trials.
  • Addressing trial design and eligibility criteria is crucial for advancing GBM therapies.
  • Improved trial conduct is essential to overcome therapeutic stagnation in glioblastoma.
