Study Overview

• Status: Completed
• Conditions: Diffuse Intrinsic Pontine Glioma
• Intervention / Treatment: Drug: Cilengitide dose escalation; Radiation: Concomitant radiotherapy; Biological: Pharmacokinetic; Biological: Pharmacogenetic; Drug: Cilengitide; Biological: Exploratory investigation

Detailed Description

The prognosis of children and young adults with a malignant glioma in the brain stem or a recurrent malignant glioma (in whatever site) is very poor. Over the last few decades, many therapeutic trials have been performed but have failed to significantly improve survival in these patients. There is thus a need to test new drugs in these indications. There is a strong biological rationale for the use of anti-angiogenic drugs in high-grade glioma. Cilengitide (EMD121974; Merck KgaA, Darmstadt, Germany), a cyclic pentapeptide containing the sequence RGD (cyclo-[Arg-Gly-Asp-Dphe-(NmeVal)]) is a selective antagonist of integrins αvβ3 and αvβ5, which are strongly involved in tumour angiogenesis. Positive results with Cilengitide in preclinical models of glioblastoma, its particularly attractive safety profile and its encouraging efficacy in phase I and II studies in adults and children make it a potentially effective molecule for the treatment of malignant glioma in children. Furthermore, its combination with radiotherapy to be appears synergistic, without any apparent increase in toxicity.

In this study, Cilengitide will be evaluated when concurrently administered with radiotherapy as a first-line treatment and then as a maintenance monotherapy in children and young adults with malignant brain stem glioma. The main objective will be to determine the maximum tolerated dose (MTD) of Cilengitide when administered twice weekly as a 60-minute intra-venous infusion.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Dose escalation; In the first part of the trial, a dose-ranging study in ca. 18-21 patients will be done. A standard dose escalation strategy will be used including 3 to 6 patients at each dose level, the first cohort of patients being treated at dose level one Interventions : Cilengitide dose escalation ; Concomitant radiotherapy ; Pharmacokinetic ; Pharmacogenetic	Drug: Cilengitide dose escalation; Cilengitide will be administered intravenously over 60 minutes, twice a week, at a given dose. The Cilengitide dose (mg/m²/infusion)levels are as follows : 240; 480; 720; 1200; 1800; Other Names: Cilengitidine; Radiation: Concomitant radiotherapy; 1.8 Gy per fraction for a total of 54 Gy over 6 weeks, from monday to friday of the first cycle. The radiation will imperatively begin between 3 and 7hours after the end of Cilengitide infusion.; Biological: Pharmacokinetic; A pharmacokinetic assessment for Cilengitide will be carried for all patients. The pharmacokinetic (PK) samples will be drawn during day 1 and day 2 of the first cycle of treatment.; Biological: Pharmacogenetic; For every patient 1 blood sample will be taken before study treatment.
