Study of RAD001 for Treatment of NF2-related Vestibular Schwannoma

A Single Arm, Monocenter Phase II Trial of RAD001 as Monotherapy in the Treatment of Neurofibromatosis Type 2 - Related Vestibular Schwannoma

The purpose of the study is to determine if RAD001 treatment will shrink or slow the growth of the vestibular schwannoma(s) in Neurofibromatosis 2 (NF2) patients. Secondary objectives include determining if RAD001 treatment will improve hearing ability in NF2 patients.

RAD001 is an oral drug that is approved by Food and Drug Administration (FDA) for other types of tumors, it is not approved by the FDA for treatment of NF2 related tumors.

This protocol is a Phase II, open-label, efficacy and safety study of single-agent RAD001 in patients with NF2. During the study, subjects will receive continuous daily oral treatment with RAD001 for up to 1 year or until tumor progression.

Primary Objective: To determine whether RAD001 has an effect on the VS growth in patients with NF2 at a rate sufficient to submit the drug for further testing.

Secondary Objectives: To determine whether RAD001 has an effect on the volume of other intracranial tumors, and to assess the effect of RAD001 on hearing function in patients with NF2 (when applicable).
