Brief Summary:
This is a phase II prospective, randomized, double-blind, longitudinal study evaluating whether the administration of aspirin can delay or slow tumor growth and maintain or improve hearing in VS patients.

Condition or disease Intervention/treatment Phase
Vestibular Schwannoma Acoustic Neuroma Neurofibromatosis 2 Drug: Aspirin Drug: Placebo Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 300 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: In the Randomized Treatment Phase, patients aged 12 years or older with VSs will be identified and recruited into one of two randomized groups who receive either 1) 325 mg aspirin twice daily (81 mg aspirin twice daily for pediatric patients <50 kg); or 2) a placebo. Patients will stay on aspirin/placebo as long as there is no more than 20% increase in VS volume. At tumor progression, patients will enter the Open Label Follow Up Phase. Patients who progress on placebo will receive unblinded aspirin. Patients who progress on aspirin (either blinded or unblinded) will be taken off study drug and followed. All patients will be followed for at least 3.5 years after randomization.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Prospective, Randomized, Placebo-Controlled Phase II Trial of Aspirin for Vestibular Schwannomas
Actual Study Start Date : June 11, 2018
Estimated Primary Completion Date : February 2021
Estimated Study Completion Date : February 2022

Arm Intervention/treatment
Experimental: Aspirin
Patients on the experimental arm will receive blinded aspirin. Pediatric subjects who weigh less than 110 lbs will take 81mg aspirin twice a day. All other subjects will take 325mg aspirin twice a day.
Drug: Aspirin
Twice daily aspirin

Placebo Comparator: Placebo
Patients on the placebo arm will receive blinded placebo and take it twice a day.
Drug: Placebo
Twice daily placebo

Primary Outcome Measures :
  1. Progression Free Survival [ Time Frame: Progression, or around 3.5 years ]
    Progression Free Survival (PFS) is the length of time from start of study treatment to tumor growth of more than 20%.
