Adaptive trial design in glioblastoma
There have been few treatment advances for patients with
glioblastoma (GBM) despite increasing scientific understanding of
the disease. While factors such as intrinsic tumor biology and
drug delivery are challenges to developing efficacious therapies,
it is unclear whether the current clinical trial landscape is
optimally evaluating new therapies and biomarkers. We queried
ClinicalTrials.gov for interventional clinical trials for patients
with GBM initiated between January 2005 and December 2016 and
abstracted data regarding phase, status, start and end dates,
testing locations, endpoints, experimental interventions, sample
size, clinical presentation/indication, and design to better
understand the clinical trials landscape. Only approximately
8%–11% of patients with newly diagnosed GBM enroll on clinical
trials with a similar estimate for all patients with GBM. Trial
duration was similar across phases with median time to completion
between 3 and 4 years. While 93% of clinical trials were in phases
I–II, 26% of the overall clinical trial patient population was
enrolled on phase III studies. We use the results of this meta
analysis to discuss pros and cons of trial designs in GBM. This
analysis includes platforms and the use of external controls.
Platform design allow to add new experimental arms to the clinical
study when they become available, while the aim of an external
controls is to leverage external data that were not generated from
the clinical study.
