Panitumumab and Irinotecan for Malignant Gliomas

Summary

This is a phase II study of the combination of panitumumab with irinotecan in malignant glioma patients. The primary objective of the study is to determine the activity of the combination of panitumumab with irinotecan as measured by 6-month progression-free survival. Secondary objectives include the following- to determine the safety of panitumumab in combination with irinotecan in patients with malignant glioma; to determine the effect of panitumumab in combination with irinotecan on corticosteroid dose for each patient; to explore any relationship between epidermal growth factor receptor (EGF-R) mutational analysis and efficacy or toxicity; and, to determine the response rate and overall survival of recurrent glioblastoma (GBM) patients treated with panitumumab in combination with irinotecan.

The patients will have histologically documented grade 4 malignant gliomas (glioblastoma multiforme or gliosarcoma) that have failed at least one prior chemotherapy regimen and all patients will have received radiation therapy. This study will investigate second or greater line of therapy for recurrent grade 4 malignant glioma. The patient population will include 32 patients.

The patients will undergo a baseline magnetic resonance imaging (MRI) as well as a MRI after every six-week cycle to determine response and progression. After 16 patients with recurrent GBM are treated, an interim analysis will be conducted. The most common side effects associated with panitumumab have been dermatological (skin) problems such as erythema (redness of the skin), acneiform rash (skin eruptions of the face), skin exfoliation, pruritus (itching), skin fissures (skin tears), xerosis (dryness of the eye, skin, or mouth), and rash. The most common side effects associated with irinotecan have been decreased blood counts of platelets (increased risk of bleeding), white blood cells (increased risk of infection), red blood cells (anemia); diarrhea, constipation, nausea, vomiting, tiredness, fever, mouth sores, dehydration (excessive loss of body fluids), rash, itching, changes in skin color, swelling, numbness, tingling, dizziness, confusion, low blood pressure, sweating, hot flashes, hair loss, inflammation of the liver, flu-like symptoms, decreased urine output, shortness of breath, and pneumonia (inflammatory disease of the lungs).

Conditions

• Malignant Glioma of Brain

Interventions

DRUG

Irinotecan

Irinotecan: for those patients on an enzyme-inducing anti-epileptic drug (EIAED), irinotecan will be dosed at 340 mg/m2 every other week. For those not on an EIAED, irinotecan will be dosed at 125 mg/m2. Treatment on both drugs will continue until tumor progression or unacceptable toxicity.

DRUG

Panitumumab

Panitumumab, 6 mg/kg, as an intravenous infusion every other week. Treatment on both drugs will continue until tumor progression or unacceptable toxicity.
