Immuntherapy for children and adolescents with high-risk refractory cancers - INFORM2-NivEnt

“INFORM2 exploratory multinational phase I/II combination study of nivolumab and entinostat in children and adolescents with refractory high-risk malignancies”

Pediatric patients aged 2-21 years with refractory/relapsed/progressive high-risk malignancies with a high mutational load (group A), with MYC(N) amplification or ATRT-MYC subgroup (group C) and with high Tcell infiltration or tertiary lymphoid structures (group E) are eligible for this trial. Extensive molecular profiling (e.g. INFORM Registry) is mandatory before inclusion into the trial. Patients receive a combination therapy with entinostat and nivolumab.

Nivolumab is an immune-checkpoint inhibitor and is already approved in Europe for adults. Entinostat is a novel class I selective HDACi. Clinical trials investigating the combination of nivolumab and entinostat in children have not been reported so far.

In this study the safety and activity of the combination treatment with entinostat and nivolumab for the age groups 2-11 and 12-21 years is evaluated.

The inclusion of patients in Germany is possible since 26.07.2019.

  • Children and adolescents with refractory/relapsed/progressive high-risk malignancies
  • No standard of care treatment available
  • Age at registration ≥ 2 to ≤ 21 years
  • Molecular analysis for biomarker identification e.g. via INFORM molecular diagnostic platform
  • Time between biopsy/puncture/resection of the current refractory/relapsed/progressive tumor and registration ≤ 24 weeks. In patients receiving therapy not impacting stratification, time between biopsy/puncture/resection of the current refractory/relapsed/progressive tumor and registration of ≤ 36 weeks is allowed.
  • Disease that is measurable as defined by RANO criteria or RECIST v1.1
