ABT-888 and Temozolomide in Treating Young Patients With Recurrent or Refractory CNS Tumors

Completed · Phase 1

Conditions studied: Childhood Atypical Teratoid/Rhabdoid Tumor, Childhood Central Nervous System Germ Cell Tumor, Childhood Choroid Plexus Tumor, Childhood Craniopharyngioma, Childhood Ependymoblastoma, Childhood Grade I Meningioma, Childhood Grade II Meningioma, Childhood Grade III Meningioma, Childhood High-grade Cerebellar Astrocytoma, Childhood High-grade Cerebral Astrocytoma, Childhood Infratentorial Ependymoma, Childhood Low-grade Cerebellar Astrocytoma, Childhood Low-grade Cerebral Astrocytoma, Childhood Medulloepithelioma, Childhood Mixed Glioma, Childhood Oligodendroglioma, Childhood Supratentorial Ependymoma, Recurrent Childhood Brain Stem Glioma, Recurrent Childhood Brain Tumor, Recurrent Childhood Cerebellar Astrocytoma, Recurrent Childhood Cerebral Astrocytoma, Recurrent Childhood Ependymoma, Recurrent Childhood Medulloblastoma, Recurrent Childhood Pineoblastoma, Recurrent Childhood Spinal Cord Neoplasm, Recurrent Childhood Subependymal Giant Cell Astrocytoma, Recurrent Childhood Supratentorial Primitive Neuroectodermal Tumor, Recurrent Childhood Visual Pathway and Hypothalamic Glioma

In brief

This phase I trial is studying the side effects and best dose of ABT-888 when given in combination with temozolomide in treating young patients with recurrent or refractory CNS tumors. ABT-888 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving ABT-888 together with temozolomide may kill more tumor cells.

Who can join

Age: any, up to 21. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients with a diagnosis of a primary CNS malignancy (including low-grade glioma) that is recurrent or refractory to standard therapy and for which there is no known curative therapy; all patients must have had histological verification of malignancy at initial diagnosis or relapse, excluding patients with diffuse intrinsic brain stem tumors, optic pathway tumors or CNS germ cell tumors with elevations of reliable serum or CSF tumor markers (alpha-fetoprotein or beta-HCG); patients with intrinsic pontine gliomas or optic pathway tumors do not require histological confirmation of disease but should have clinical and/or radiographic evidence of progression
• Patients must have Karnofsky Performance Score (for patients > 16 years of age) or Lansky Performance Score (for patients =< 16 years of age) >= 50% assessed within two weeks of study enrollment
• Patients must be able to take oral medications (either capsules or liquid); patients with neurologic deficits must have been stable for a minimum of 1 week prior to study entry; patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
• Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study; recovery is defined as all AE"s, attributable to prior therapy, having improved to grade 2 or better or as outlined below
• Myelosuppressive chemotherapy:
• Patients must have received their last dose of known myelosuppressive anticancer chemotherapy at least three (3) weeks prior to study registration
• Patients must have received their last dose of nitrosourea (including Gliadel) at least six (6) weeks prior to study registration
• Biologic agent (anti-neoplastic): Patient must have received their last dose of other biologic agent ≥ 7 days prior to study registration
• For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair
• Monoclonal antibody treatment: Patient must have received their last dose of monoclonal antibody ≥ 4 weeks prior to registration
• Radiation - Patients who have had prior radiation must have had their last fraction of:
• Craniospinal irradiation or total body irradiation > 3 months prior to registration
• Local irradiation to the primary tumors or other sites (cumulative dose ≥ 40Gy) > 3 months prior to registration
• Palliative irradiation delivered to symptomatic metastatic sites > 4 weeks prior to registration
• Stem Cell Transplant: Patient must be:
• ≥ 6 months since allogeneic stem cell transplant prior to registration
• ≥ 3 months since autologous stem cell transplant prior to registration
• Corticosteroids: Patients who are receiving dexamethasone must be on a stable or decreasing dose for at least 1 week prior to registration
• Growth factors:
• Off all colony forming growth factor(s) that support platelet or white blood cell count, number or function for at least 1 week prior to registration (filgrastim, sargramostim, erythropoietin)
• Off Pegylated G-CSF and/or Erythropoiesis Stimulating Protein for at least 14 days prior to registration
• Temozolomide: Patients who have received temozolomide previously are eligible for this study if they meet all other inclusion and exclusion criteria
• Organ Function: Documented within 14 days of registration and within 7 days of starting treatment
• Hgb > 8 gm/dL (transfusion independent)
• Platelet count > 100,000/mm\^3 (transfusion independent)

You may not qualify if…

• Patients receiving any of the following medications are not eligible for study entry:
• Anti-cancer therapy
• Investigational agents
• Patients with any clinically significant, unrelated systemic illness (serious infections or significant cardiac, pulmonary, hepatic or other organ dysfunction), that would compromise the patient's ability to tolerate protocol therapy or would likely interfere with the study procedures or results
• Patients with uncontrolled seizures are not eligible for study entry
• Patients with inadequately controlled systemic hypertension (SBP and/or DBP > 95th percentile for age and height
• Patients with a prior history of hypertensive crisis and/or hypertensive encephalopathy
• If a BP measurement prior to registration is > 95th percentile for age and height, it must be rechecked and documented to be < 95th percentile for age and height prior to registration; if a patient falls between the height or weight percentiles, site should average the value as appropriate; for patients ≥ 18 years the normal blood pressure should be < 140/90 mm of Hg; patients with hypertension are eligible if their blood pressures become < 95th percentile for age and height after anti-hypertensive medications
• Patients with documented CNS ischemia and/or infarction, whether symptomatic or discovered incidentally without clinical symptoms, will be excluded from study participation
• Patients with an inability to return for follow-up visits or obtain follow-up studies required to assess toxicity to therapy
