Study Description

Brief Summary: This will be a multi-center, proof of concept phase 0 study to assess the suppression of p-AKT in Vestibular Schwannoma (VS) and meningiomas by AR-42 in adult patients undergoing tumor resection. AR-42 is a small molecule which crosses the blood brain barrier (BBB) in rodents, but the investigators are not certain yet if it will penetrate human VS. Meningiomas are outside the BBB, but seem to be unusually resistant to all current medical treatments. The primary endpoint of the bioactivity of suppression of p-AKT by AR-42 was selected as drug activity seems more informative than bioavailability. Our preclinical data and others have shown dose dependent suppression of p-AKT by AR-42 in both VS and meningiomas.

Detailed Description: This is a multi-center, proof of concept phase 0 study to assess the suppression of p-AKT in VS and meningiomas by AR-42 in adult patients undergoing NF2-tumor resection. AR-42 will be administered three times per week beginning 3 weeks prior to surgery. A total of ten doses, +/- 1 dose at 40 mg/dose, will be self-administered orally by study participants at approximately the same time every day (+/- 1 hour, preferably in the evening) 3 times per week for 3 weeks pre-operatively, with the last dose taken the night before surgery. Patients will be evaluated within the context of their standard post-operative follow up which includes within 2 days of surgery and again at 2 weeks (+/- 10 days) after surgery. Samples will be shipped to the participating laboratories (OSU Comprehensive Cancer Center (CCC) Pharmacoanalytical Shared Resource (PhASR) and Nationwide Children's Research Institute) for assessment of intratumoral drug concentration and assessment of intratumoral disease markers. During surgery, four blood samples will also be obtained and sent to the cooperating laboratory (PhASR) for determination of drug concentration and molecular analysis.
