Summary:
This phase I trial studies the side effects and best dose of trametinib with or without whole
brain radiation therapy in treating patients with brain metastases. Trametinib may stop the
growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation
therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs, such as
trametinib, may make tumor cells more sensitive to radiation therapy. Giving trametinib with
whole brain radiation therapy may be a better treatment for brain metastases.
Detailed description:
PRIMARY OBJECTIVES:
I. To identify the maximally tolerated dose of trametinib to be used in combination with
whole brain radiation therapy in patients with brain metastases. (Cohort A) II. To quantify
trametinib in resected brain metastatic lesions utilizing high performance liquid
chromatography/tandem mass spectrometry (LC/MS/MS) and compare to quantification of adjacent
tissues: brain margin, arachnoid, and cerebrospinal fluid (CSF). (Cohort B)
SECONDARY OBJECTIVES:
I. To evaluate the tolerability and feasibility of the combination of trametinib and
radiation therapy to brain for brain metastases.
II. To evaluate the objective response rate per Response Evaluation Criteria in Solid Tumors
(RECIST) criteria of combination trametinib and radiation therapy.
III. To evaluate the local control rate, as measure from the time of study enrollment until
the time of death.
IV. To evaluate the neurologic progression-free survival, as measured from the time of study
enrollment until the time of progression within the brain or death.
V. To evaluate overall survival, as measured from the time of study enrollment until the time
of death.
TERTIARY OBJECTIVES:
I. To quantify cyclin D1, p27, phosphorylated mitogen-activated protein kinase 1 (pERK)-1/2,
phosphorylated v-akt murine thymoma viral oncogene homolog 1 (pAKT), phosphatase and tensin
homolog gene (PTEN), phosphorylated mammalian target of rapamycin (pMTOR), phosphorylated
ribosomal protein S6 kinase (pS6K), and ribosomal protein S6 (pS6) of resected metastatic
brain lesions via quantitative immunohistochemistry (IHC) and compare to the IHC profile of
the primary tumor.
OUTLINE: This is a dose-escalation study of trametinib. Patients are assigned to 1 of 2
treatment cohorts.
COHORT A: Patients receive trametinib orally (PO) once daily (QD) for 4 weeks. Beginning in
week 2, patients undergo whole brain radiation therapy five days a week for 3 weeks.
Treatment continues for 4 weeks in the absence of disease progression or unacceptable
toxicity.
COHORT B: Patients receive trametinib PO QD on days 1-14 followed by surgical resection of
the tumor.
After completion of study treatment, patients are followed up for 4 weeks, every 2 months for
1 year, every 3 months for 3 years, and then every 6 months thereafter.
