About this study

Official title: Phase II Study of Axitinib in Patients With Neurofibromatosis Type 2 and Progressive Vestibular Schwannomas

The purpose of this study is to determine if the study drug, AXITINIB, has any effect on tumors found in patients with Neurofibromatosis Type 2 (NF2).

Read the detailed description

NF2 is a condition that mainly affects the skin and nervous system. It causes non-cancerous tumors to grow on the nerves around a person's body. Some signs of NF2 include a gradual loss of hearing and tumors growing on the skin, the brain and the spinal cord, which can lead to complications.

AXITINIB is an oral drug (taken by mouth) that is approved by the United States Food and Drug Administration (FDA) for the treatment of other types of tumors. However, in this research study, AXITINIB is considered investigational because it is not approved by the FDA for treatment of NF2. Much is known regarding how well it is tolerated (handled), but investigators do not know if it is effective in treating NF2.

This research study will test whether AXITINIB may shrink tumors commonly found in patients with NF2 or stop them from growing. This will help to decide if AXITINIB should be used to treat NF2 patients in the future. AXITINIB is a drug that has been used to treat various forms of cancer. It has not been studied for the treatment of tumors in NF2 patients. Investigators have selected AXITINIB for this clinical trial in patients with NF2 and NF2-related tumors because a very similar drug, bevacizumab, can shrink Vestibular Schwannomas (VS) in some NF2 patients.

Pfizer, Inc., the manufacturer of the study drug, AXITINIB, will provide the AXITINIB being used in this study.

Primary Objective: To estimate the objective volumetric response rates to axitinib in adult NF2 patients with VS.

Secondary Objectives: To assess the toxicity of axitinib given daily in patients with NF2 and to examine the association of objective measures of response on MRI, i.e. volumetric tumor analysis with clinical measures of response, i.e. (audiogram), as well as quality of life assessments (NFTI-QOL). In addition, response in non-VS tumors, such as other schwannomas and meningiomas, may be explored.

AxitinibExperimental5 mg axitinib orally twice daily, with increase to 7 mg orally twice daily and 10 mg orally twice daily after 2 and 4 weeks, respectively, provided no adverse reactions (i.e., not exceeding grade 2 toxicities) and normotensive and not receiving antihypertension medications. Axitinib will be given continuously in 28-day cycles until disease progression or unacceptable toxicity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Expression Levels of p-S6 Based Immunohistochemistry (Histoscore)

    The histoscore is given as the sum of the percentage of staining multiplied by an ordinal value corresponding to the intensity level (0 = none, 1 = weak, 2 = moderate, 3 = strong). With 4 intensity levels, the resulting score ranged from 0 (no staining in the tumor) to 300 (diffuse intense staining of the tumor).

    Measured: 10 days

  2. Expression Levels of p-ERK Based Immunohistochemistry (Histoscore)

    The histoscore is given as the sum of the percentage of staining multiplied by an ordinal value corresponding to the intensity level (0 = none, 1 = weak, 2 = moderate, 3 = strong). With 4 intensity levels, the resulting score ranged from 0 (no staining in the tumor) to 300 (diffuse intense staining of the tumor).

    Measured: 10 days

  3. Expression Levels of p-AKT Based Immunohistochemistry (Histoscore)

    The histoscore is given as the sum of the percentage of staining multiplied by an ordinal value corresponding to the intensity level (0 = none, 1 = weak, 2 = moderate, 3 = strong). With 4 intensity levels, the resulting score ranged from 0 (no staining in the tumor) to 300 (diffuse intense staining of the tumor).

    Measured: 10 days

  4. Pre-Operative Everolimus Blood Levels

    Measured: Baseline

  5. Post-Operative Everolimus Blood Levels

    Measured: 10 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Axitinib in people with Neurofibromatosis Type 2 and Vestibular Schwannomas, run by NYU Langone Health at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 35 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Expression Levels of p-S6 Based Immunohistochemistry (Histoscore) (time frame: 10 days). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2021.
