  Purpose

Background:

- AZD6244 is an experimental drug designed to prevent tumor growth and shrink existing tumors. It has been studied in adults with cancer, but it has not been studied in children with cancer. Researchers want to see if AZD6244 is a safe and effective treatment for older children and young adults who have gliomas (brain tumors) that have not responded to standard treatments.

Objectives:

- To test the safety and effectiveness of AZD6244 in older children and young adults who have gliomas that have not responded to standard treatments.

Eligibility:

- People between 12 and 21 years of age who have gliomas that have not responded to standard treatments.

Design:

  • Participants will be screened with a medical history and physical exam. They will also have blood tests and tumor imaging studies. Those in the study may also have their spinal fluid tested to see whether the cancer has spread to other parts of the nervous system.
  • Participants will take AZD6244 as a capsule. It must be swallowed whole on an empty stomach twice a day for 28 days. Those in the study will have up to 13 cycles (4 weeks each) of treatment (1 year).
  • Participants will keep a diary to record doses taken and any side effects of the treatment.
  • Participants will have frequent blood tests and imaging studies.

Criteria
  • INCLUSION CRITERIA

3.1.1 Tumor

Patients with sporadic (non NF-1 associated), histologically diagnosed pilocytic astrocytoma who have pre- treatment tumor tissue available for BRAF analysis are eligible. NF-1 patients with radiographic evidence of low grade glioma, with or without histological diagnosis are also eligible. Patients will be assigned to one of 4 strata following enrollment.

  • Stratum 1: Patients with progressive, recurrent or refractory pilocytic astrocytoma with pre-trial tumor material available and with a BRAF aberration i.e. BRAF (V600E) mutation and/or BRAF KIAA1549 fusion as determined by IHC and FISH, respectively.
  • Stratum 2: Patients with progressive, recurrent or refractory pilocytic astrocytoma with pre-trial tumor material available and without a BRAF aberration i.e. BRAF (V600E) mutation and/or BRAF KIAA1549 fusion as determined by IHC and FISH, respectively.
  • Stratum 3: Patients with Neuro-fibromatosis 1 (NF-1) associated progressive, recurrent or refractory low grade glioma (WHO Grade I & II), with or without tissue
  • Stratum 4: Non-NF-1 recurrent or refractory pilocytic astrocytoma patients who cannot be classified into Stratum 1 or 2 due to inadequate tissue quality or assay failure.

3.1.2 Patients must have bi-dimensionally measureable disease defined as at least one lesion that can be accurately measured in at least two planes in order to be eligible for this study.

3.1.3.4 Radiation: Patients must have:

  • Had their last fraction of local irradiation to primary tumor (Bullet)12 months prior to registration; investigators are reminded to review potentially eligible cases to avoid confusion with pseudo-progression.

3.1.3.5 Corticosteroids: Patients who are receiving dexamethasone must be on a stable or decreasing dose for at least 1 week prior to registration.

3.1.12 Pregnancy Prevention

The effects of AZD6244 on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation, and for four weeks after dosing with AZD6244 ceases. Women of child-bearing potential must have a negative pregnancy test prior to entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Please note that the AZD6244 manufacturer recommends that adequate contraception for male patients should be used for 16 weeks post-last dose due to sperm life cycle.
