Cilengitide in Treating Children With Refractory Primary Brain Tumors

Study Purpose

This phase I trial is studying the side effects and best dose of cilengitide in treating children with recurrent, progressive, or refractory primary CNS tumors. Cilengitide may slow the growth of brain cancer cells by stopping blood flow to the tumor.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

  • - GFR > 70 ml/min/1.73m^2.
  • - Total bilirubin ≤ upper limit of normal for age.
  • - SGPT (ALT) and SGOT (AST) < 2.5 times upper limit of normal.
  • - Cilengitide was teratogenic when tested in animals; as such, female patients of childbearing potential must have a negative serum or urine pregnancy test prior to study entry; female patients must avoid breast feeding while on study.
  • - Patients of childbearing potential must be willing to use a medically acceptable form of birth control, which includes abstinence, while being treated on this study.
  • - Signed informed consent according to institutional guidelines must be obtained prior to patient registration.

Exclusion Criteria:

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT00063973
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

PRIMARY OBJECTIVES:

  • I. To describe the acute and dose-limiting toxicities (DLT) and define the maximum tolerated dose (MTD) of cilengitide (EMD 121974) when administered to children and adolescents with refractory primary brain tumors.
SECONDARY OBJECTIVES:
  • I. To obtain preliminary evidence of biologic activity by determining alterations in tissue perfusion, tumor blood flow and metabolic activity using MR perfusion, PET and MRS and correlating these findings with changes in tumor size by volumetric MRI.
  • II. To characterize inter- and intra-patient variability in the pharmacokinetics of cilengitide and to estimate cilengitide renal clearance in this patient population.
  • III. To characterize the pharmacogenetic polymorphisms in drug transporters (e.g., MRP4, BCRP) and relate to cilengitide disposition.
  • IV. To evaluate changes in circulating endothelial cells (CECs) and circulating endothelial precursors (CEPs) in patients treated with cilengitide, and to investigate the correlation between changes in CECs and CEPs, plasma, serum and urine angiogenic protein levels such as VEGF, and clinical outcome.
  • V. To obtain preliminary information about the efficacy of cilengitide in this patient population.
OUTLINE: This is a dose-escalation, multicenter study. Patients receive cilengitide (EMD 121974) IV over 1 hour twice weekly. Treatment repeats every 4 weeks for 13 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of cilengitide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 25% of patients are expected to experience dose-limiting toxicity. Once the MTD is determined, 6 additional patients are accrued and treated at that dose level for a total of 12 patients at the MTD. Patients receiving treatment are followed weekly for the first three months then monthly for one year or 13 courses of treatment. Patients discontinuing treatment will be followed for resolution of all adverse events occurring while on treatment and/or within 30 days of the last administration of study drug. Patients will be followed for the shortest of 1) three months after the last protocol based treatment, or 2) the date other therapy is initiated.
