Abstract

The HERBY trial was a phase II open-label, randomized, multicenter trial evaluating bevacizumab (BEV) in addition to temozolomide/radiotherapy in patients with newly diagnosed non-brainstem high-grade glioma (HGG) between the ages of 3 and 18 years. We carried out comprehensive molecular analysis integrated with pathology, radiology, and immune profiling. In post-hoc subgroup analysis, hypermutator tumors (mismatch repair deficiency and somatic POLE/POLD1 mutations) and those biologically resembling pleomorphic xanthoastrocytoma ([PXA]-like, driven by BRAF_V600E or NF1 mutation) had significantly more CD8+ tumor-infiltrating lymphocytes, and longer survival with the addition of BEV. Histone H3 subgroups (hemispheric G34R/V and midline K27M) had a worse outcome and were immune cold. Future clinical trials will need to take into account the diversity represented by the term “HGG” in the pediatric population. In a pediatric high-grade non-brainstem glioma cohort, Mackay et al. show that hypermutator tumors and those resembling pleomorphic xanthoastrocytoma are highly infiltrated by CD8+ lymphocytes and benefit from the addition of bevacizumab, whereas the histone H3 subgroups are immune cold and have a poor outcome.

Funding

The HERBY clinical trial was carried out as a collaboration between the European Innovative Therapies for Children with Cancer (ITCC) consortium, the SIOPE Brain Tumor Group, the Australian Children's Cancer Trials Group (ACCT), and the C-17 Council (Canada). The translational research study was funded by an unrestricted grant from F. Hoffmann-La Roche Ltd allied to the HERBY trial (study number BO25041; clinicaltrials.gov NCT01390948). The funder provided infrastructure for sample acquisition, shipping, storage, and record keeping. The funder had no role in study design, data collection, data analysis, data interpretation, or writing of the report. We acknowledge the excellent technical assistance of staff at the Tumor Profiling Unit at the Institute of Cancer Research, London, UK, Sainte-Anne Hospital, Paris, France, and HistoGeneX, Antwerp, Belgium.

We would like to thank the local investigators, pathologists and radiologists who took part in the HERBY study, and the patients and families who consented to inclusion in the translational research program.
