AT-30EFFECTS OF EVEROLIMUS ON MENINGIOMA GROWTH IN PATIENTS WITH NEUROFIBROMATOSIS TYPE 2

ABSTRACT: BACKGROUND: Vestibular schwannomas (VS) and meningiomas are associated with biallelic loss of NF2, and may arise sporadically or in the context of the tumor predisposition syndrome neurofibromatosis type 2. Loss of NF2 activates the mammalian target of rapamycin (mTOR) pathway, and published in vitro and in vivo data indicate that mTOR inhibition may be effective in the treatment of NF2-deficient VS and meningiomas. Everolimus is an oral inhibitor of mTOR complex 1 (mTORC1) with anti-tumor activity in a variety of tumors. METHODS: We conducted a retrospective review of patients with NF2 and progressive vestibular schwannomas treated with everolimus on our prospective phase II clinical trial (ClinicalTrials.gov NCT01419639). Everolimus was administered at a daily dose of 10 mg in continuous
