Phase I Study of Tipifarnib with Radiation Therapy to Treat Glioblastoma Multiforme

This study is currently recruiting patients.

Sponsored by

National Cancer Institute (NCI)
Purpose

The purposes of this study are the following:

- To find a safe dose of Tipifarnib (also known as R115777 or ZARNESTRA) to be given with radiation therapy in patients who are, and who are not, taking the following anti-seizure medications: Dilantin, Tegretol, Carbatrol, Trileptal, and Mysoline;

- To determine the safety and side effects of Tipifarnib and radiation therapy when given to patients with glioma (a type of brain tumor); and,

- To determine if gliomas shrink when Tipifarnib is given with radiation therapy.

Current post-surgical treatment of malignant (cancerous) gliomas with chemotherapy is disappointing. This study will test whether the findings of a recent pilot study suggesting a possible beneficial effect of Tipifarnib in patients with recurrent malignant gliomas can be confirmed.

Patients 18 years of age and older with glioblastoma multiforme who have not received prior radiation therapy to the brain or cytotoxic or non-cytotoxic experimental drug therapy against the brain tumor may be eligible for this study. Patients may have received corticosteroids, antiepileptics, pain killers, and other drugs to treat symptoms or prevent complications. Candidates will be screened with a physical examination, magnetic resonance imaging (MRI) or computed tomography (CT) scan of the brain, and routine laboratory tests.

Participants will receive Tipifarnib twice a day by mouth for 21 days, followed by 7 days without drug. This regimen constitutes one treatment cycle. These 4-week cycles will be repeated as long as the patient´s disease does not worsen and the side effects of treatment are acceptable. After beginning treatment with Tipifarnib, patients will receive standard radiation therapy for glioblastoma. Radiation therapy lasts approximately 6 weeks.

During treatment with R115777 and radiation therapy, participants will be seen in the clinic once a week. After radiation is completed, they will be seen every 4 weeks. Blood will be drawn once a week during radiation therapy and once every 2 weeks after completing radiation therapy. Patients will also have periodic physical and neurologic examinations. Brain MRI or CT scans will be done at diagnosis, after surgery, 4 weeks after completion of radiation therapy, and then at 8-week intervals.

Further Study Details:

Malignant gliomas are an important cause of cancer-related morbidity and mortality in the United States. Post-surgical treatment of malignant gliomas has been disappointing. Radiation therapy increases median survival from about 3-4 months to 8-9 months for GBM. Traditional chemotherapy adds only modestly to that. Given the relatively poor activity of most cytotoxic agents in the treatment of malignant gliomas, new agents with novel mechanism of action are needed. The farnesylation of proteins is catalyzed by the enzyme farnesly protein transferase (FPT). Although several substrate proteins for FPT have been identified, attention has focused on RAS proteins. Several Lines of investigation indicate that these, molecular switches, exert proliferative and anti-apoptotic effects through a variety of mechanisms, including cytokine-driven signal transduction and cell cycle progression. Indeed, mutated ras proteins are prevalent in a wide variety of malignancies. Hence, FPT represents a novel, albeit indirect, target for rationally designed antineoplastic therapy. R115777 is an orally bioavailable methyl-quinolone, which has been shown to be a potent and selective inhibitor of FPTase both in vitro and in vivo. The previous NABTC study 99-01 details modest efficacy in patients with this disease. There exists data supporting the additive/synergistic effects of FTIs with radiation. This protocol attempts to define the toxicities associated with XRT and R115777 used concomitantly at MTD as a, lead-in, to a Phase II study to be performed by RTOG. The present proposal seeks to confirm, in first-line treatment, the findings of a recent pilot trial, which suggested a possible beneficial effect of R115777 in patients with recurrent malignant gliomas.

Eligibility

Genders Eligible for Study: Both

Criteria

INCLUSION CRITERIA:
Patients will have histologically proven intracranial Glioblastoma Multiforme (GBM) or gliosarcoma (GS).
Diagnosis will have been established by biopsy or resection within 4 weeks prior to registration.
Cranial MRI or contrast CT must have been performed within 21 days of study entry. The use of MRI rather than CT is preferred. The same type of scan, i.e., MRI or CT must be used throughout the period of protocol treatment for tumor measurement. If the surgical procedure was a resection, cranial MRI or contrast CT performed with 96 hours of resection is preferred but not required. Patients without measurable or assessable disease are eligible.
Patients must have a plan to begin partial brain radiotherapy within 5-9 days after beginning R115777, and within 35 days (5 weeks) of the surgical procedure that established the diagnosis.
Patients must be willing to forego cytotoxic and non-cytotoxic drug therapy against the tumor while being treated with R115777.
All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must be registered in the North American Brain Tumor Consortium Data Management Center (NABTC DMC) database prior to treatment with study drug.
Patients must be greater than or equal to 18 years old, and with a life expectancy greater than 8 weeks.
Patients must have a Karnofsky performance status of greater than or equal to 60.
Patients must have adequate bone marrow function (WBC greater than or equal to 3,000/ul, ANA greater than or equal to 1,500/mm (3), platelet count of greater than or equal to 100,000/mm(3), and hemoglobin greater than or equal to 10 gm/dl) and the test must be performed within 14 days prior to registration. Eligibility level for hemoglobin may be reached by transfusion.
Patients must have adequate liver function (SGOT and bilirubin less than 2 times ULN) and the test must be performed within 14 days prior to registration.
Patient must have adequate renal function (creatinine less than 1.5 mg/dL) before starting therapy and the test must be performed within 14 days prior to registration.

EXCLUSION CRITERIA:
Patients must not have received previous radiotherapy to the brain.
Patients must not have received cytotoxic drug therapy, non-cytotoxic drug, or experimental drug therapy directed against the brain tumor. Patients who received Gliadel wafers will be excluded
Patients may have received or be receiving corticosteroids, antiepileptics, analgesics, and other drugs to treat symptoms or prevent complications.
Patients must not have any significant medical illnesses that in the investigator´s opinion cannot be adequately controlled with appropriate therapy or would compromise the patient´s ability to tolerate this therapy. Patients must not have any disease that will obscure toxicity or dangerously alter drug metabolism.
Patients with a history of any other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission and off of all therapy for that disease for a minimum of 3 years are ineligible.
Males and females will be recruited with no preference to gender. No exclusion to this study will be based on race.
Patients must not have active infection.
Women must not be pregnant or Breast-feeding, and women with reproductive potential must practice adequate contraception
Patients must not be on chronic coumadin therapy for prior medical problems (e.g. cardiac valve prophylaxis). Patients who develop or have recently developed a deep venous thrombosis or pulmonary embolism who are on or will take coumadin will be allowed to participate.
