Important Facts

  1. Many medications/tumor drug-treatments have been in trials for tumor management for neurofibromatosis type 2 (NF2) tumors.
  2. Changes in tumors 2: Medications to manage NF2 tumors is up to, but rarely reduces tumor size more than twenty-percent (20%).
  3. Delay Advantage: While tumor drug-treatments only reduce tumor size, this can help delay damage tumors can do until better treatments are available and will lower risk of tumor growth changing from non-cancerous to cancerous.

Introduction

There is no cure to neurofibromatosis type 2 (NF2).

There are limits to tumor-drug treatments for tumors that grow as a result of the NF2 condition.

Except for Bevacizumab (Avastin™), NF2 tumor-drug treatments are experimental and in different phases of clinical trials.

Everyone responds differently to each treatment in some way to each treatment option, but each might result in:

  • no response to tumors at all
  • stabilize tumor size (no growth)
  • tumor size reduction with continued use of treatment
  • side effects complications not worth continuation of the treatment

Research is needed!!!

The list of tumor drug treatments here includes a breakdown of treatments in different phases of trials, and a separate listing of discontinued treatments which have proven ineffective.

Links to existing drug-based treatments include known side effects are noted when after treatment has been in trial long enough for information, therefore not all treatments include a list of possible side effects. Awareness of side effects can help allow life adjustments to continue with treatment for a longer period.

1. NF2 Drug-Based Treatments

Bevacizumab (Avastin™) and biosimilar (MVASI™)

Avastin™ is the longest running NF2 drug-based clinical trial treatment, 2009. When it works, it has the possibility of affecting Vestibular Schwannoma (VS). The rates of tumors might change are different for each tumor in the same individual when it works. Study for review of NF2 Meningioma and Ependymoma have been in early stages, started in 2015.

While Avastin™ side effects are minimal, after time, it can become hard to tolerate, and there is a chance of fast tumor regrowth during even three-month breaks for treatment vacations. Read more on side effect issues and other data collected in the Avastin - NF2 Community Informal Study.

Aspirin

The conclusion of the study done for management of indicates was on Aspirin is not helpful enough for management of vestibular schwannoma (VS) tumors.[9, 10]

Given the risk of the side effects, individuals looking for control of tumors should consider other options.

Side effects of Aspirin include; rash, gastrointestinal ulcerations, abdominal pain, upset stomach, heartburn, drowsiness, headache, cramping, nausea, gastritis, and bleeding.[11]

Potential NF2 Clinical Trials


Cruciferous Vegetables: Sulforaphane (SFN)

Sulforaphane (SFN) is an isothiocyanate found in cruciferous vegetables.

SFN is available in both food and vitamin form. Research is necessary to determine if; 1) a specific brand is ideal, 2) if a pharmacy needs to make a better compound, 3) what other than SFN might be necessary for the results seen in early trials, 4) how to determine the correct dose (height, age, weight), and tests necessary for safety.
