Carboplatin in Treating Patients with Recurrent High-Grade Gliomas

Protocol: OSU-10151

Full Title

Intracerebral convection enhanced delivery of carboplatin for treatment of recurrent high-grade gliomas


This phase I clinical trial studies the side effects and best dose of carboplatin administered by convection enhanced delivery into the tumor in patients with high grade brain tumors (gliomas). This study is a dose escalating study, (the dose of the study drug is increased at set time points). Carboplatin is in a class of drugs known as platinum-containing compounds; it slows or stops the growth of cancer cells in your body. Convection enhanced delivery involves placing one or more catheters into the brain and delivering chemotherapy through those catheters directly into the brain.

Study Objective


I. Establish the maximum tolerated dose and define the toxicity profile of carboplatin delivered intracerebrally via convection enhanced delivery (CED) for patients with high grade glial neoplasms.


I. Examine the efficacy as defined by six-month progression free survival (PFS), median progression free survival, overall survival, and the radiographic response rate.

II. Evaluate the drug distribution.

OUTLINE: This is a phase I, dose-escalation study.

Patients undergo craniotomy and then receive carboplatin intracerebrally via CED over 72 hours.

After completion of study treatment, patients are followed up every 4 weeks for 16 weeks and then every 8 weeks until 30 weeks.

Are you eligible?

Inclusion Criteria:

All patients must have progressive disease for which craniotomy and tumor resection is recommended as treatment

All patients must sign a consent form indicating that they are aware of the investigational nature of the study; the informed consent form will indicate that the patient has been made aware of all other appropriate therapies

Patients with histologically confirmed grade III or IV astrocytoma, oligoastrocytoma, and oligodendroglioma who are at first or second recurrence

All patients require an initial diagnosis of a malignant glioma as outlined in the inclusion criteria which must be confirmed at the treating facility

Patients must have unequivocal evidence of tumor progression by magnetic resonance imaging (MRI) performed no longer than 28 days prior to study registration

Patients must have pathologically confirmed recurrence at the time of catheter placement

Patients must be on a stable or decreasing dexamethasone dosage for at least 1 week prior to baseline MRI

Patients must have been treated previously with radiation therapy and treatment must have been completed at least 8 weeks prior to surgery for catheter implantation

Last dose of cytotoxic chemotherapy must have been at least 4 weeks (6 weeks for nitrosoureas) prior to catheter placement; patients are eligible if they received bevacizumab or other anti-vascular endothelial growth factor (VEGF) therapies, although the most recent dose must be at least 6 weeks prior to catheter placement

Patients previously treated with stereotactic radiosurgery, stereotactic radiotherapy, brachytherapy, Gliadel wafers or other intratumoral chemotherapy are eligible

Patients must have recovered from all prior therapy

Patients must have a life expectancy of >= 3 months and a Karnofsky performance status >= 60

Leukocytes >= 3,000/mcL

Absolute neutrophil count >= 1,500/mcL

Platelets >= 100,000/mcL

Hemoglobin >= 9 g/dL

Serum calcium =< 12.0 mg/dL

Total serum bilirubin < institutional upper limit of normal (ULN)

Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X institutional ULN

Creatinine < 1.5 X institutional ULN

Women of child bearing years must have a negative pregnancy test (serum or urine) within 1 week of study entry; men and women of reproductive potential must agree to use an effective contraceptive method including one of the following: surgical sterilization (tubal ligation for women or vasectomy for men); approved hormonal contraceptives (such as birth control pills, Depo-Provera or Lupron Depro); barrier methods (such as condom or diaphragm) used with a spermicide cream or an intrauterine device (IUD)

Patient or designated individuals with durable medical power of attorney must give written informed consent prior to any study-specific procedures being implemented

Both men and women and members of all races and ethnic groups are eligible for this trial

Exclusion Criteria:

Patients with infratentorial, multifocal, or pathologically confirmed cerebrospinal fluid (CSF) disseminated tumor

Patients that have been treated with > 3 prior chemotherapy regimens

Patients who have a history of bleeding disorders including congenital or acquired coagulopathies

Known acquired immune deficiency syndrome (AIDS) based upon current Centers for Disease Control and Prevention (CDC) definition or other acquired or congenital disorder of the immune system

Patients with unstable or serious concurrent illness including, but not limited to, ongoing or active infections requiring IV antibiotics or psychiatric illness/social situations that would limit compliance with study requirements are ineligible; (if patient has a stable chronic infection requiring oral antibiotics, the patient may be treated at the investigators discretion; however a clinical note must include the justification regarding the safety of treating the patient)

Patients who have received any other investigational agent in a 28-day period prior to enrollment in this study

Patients whose tumors are located less than 2 cm from the ventricles

Patients taking greater than 12 mg daily of dexamethasone

Prior invasive malignancy that is not low-grade glioma, glioblastoma or gliosarcoma (except non-melanomatous skin cancer or carcinoma in situ of the cervix) unless the patient has been disease free and off therapy for that disease for a minimum of 3 years
