HIT-HGG CilMetro Cilengitide and Metronomic Temozolomide for Relapsed or Refractory High Grade Gliomas or Diffuse Intrinsic Pontine Gliomas in Children and Adolescents - A Phase II Study
Disease Relapsed or Refractory High Grade Gliomas or Diffuse Intrinsic Pontine Gliomas
Type Phase-II-Studie
Rationale / Objectives

Primary objectives

To evaluate the efficacy of a combined treatment with cilengitide and metronomic oral temozolomide as measured by 6 months overall survival (OS) after diagnosis of relapse or tumour progression in children and adolescents with relapsed or refractory high-grade malignant glioma and diffuse intrinsic pontine glioma.

Secondary objectives

  1. To evaluate the safety and toxicity of the study treatment by common toxicity criteria (CTC; version 4.0).
  2. To assess - the response rates at 6 months (continuous complete response = CCR, complete response = CR, partial response = PR, stable disease = SD, progressive disease = PD) and - progression-free survival (PFS) at 6 months, and - response rates, OS, and PFS at 12 months after relapse diagnosis or diagnosis of tumor progression. Response will be presented including histopathological variants.
  3. To assess the pharmacokinetics of cilengitide administered as part of the study treatment.
Therapy / Study arms

Patients included in the study receive - cilengitide 1800 mg/m² i.v. twice weekly - temozolomide 75 mg/m²/d p.o. for 6 weeks, followed by 1 week rest with a mandatory dose adaptation rule depending of haematatological and non-haematological toxicities.

Inclusion Criteria
  • Diagnosis of high-grade malignant glioma confirmed by central neuropathological review (last MRI diagnosis not older than 4 weeks) - including glioblastoma multiforme (WHO IV), anaplastic astrocytoma (WHO III), anaplastic oligodendroglioma (WHO III),
  • anaplastic oligoastrocytoma (WHO III), anaplastic pilocytic astrocytoma (WHO III), anaplastic ganglioglioma (WHO III), anaplastic pleomorphic xanthoastrocytoma (analogous to WHO III), giant cell glioblastoma (WHO IV), and gliosarcoma (WHO IV) - or
  • diagnosis of diffuse intrinsic pontine glioma confirmed by central neuroradiological review - refractory to standard treatment, or relapsed or progressive after first-line therapy.
  • 2. Patient aged 3 years and older but under 18 years at time of relapse diagnosis

Participants 55 trial sites, associated with the participating study groups, take part in the HIT-HGG-CilMetro study. At least 33 paediatric patients with central review of their primary diagnosis as high grade glioma including diffuse intrinsic pontine glioma will be included in the trial. The trial will be opened in Germany.
