Neurofibromatosis type 1 (NF1) is a genetic disorder. It affects the skin and can cause nervous system tumors. Malignant peripheral nerve sheath tumors (MPNST) are the leading cause of death for people with NF1. They arise from nerves in the body and can spread. Researchers want to see if a combination of two drugs can help. The drugs, selumetinib and vistusertib, both affect tumor growth.


To study the effects of selumetinib plus sirolimus on people with NF1 and MPNST.


People ages 12 years and older with MPNST


Participants will be screened with:

-Medical history

-Physical exam

-Tests of pain and everyday activities

-Blood, urine, and heart tests

-Pregnancy test

-Eye exam


Participants will take both study drugs 2 times a day in 28-day cycles. They will take selumetinib every day and vistusertib the first 2 days of each week.

Participants will learn about taking the drug capsules and food and medicines to avoid. They will learn about skin and mouth care and treating diarrhea.

Participants will keep a drug diary. They may get medicine for side effects.

Participants will have 6 visits during cycle 1, and 1 visit every other cycle. During visits, participants may repeat the screening tests and:

-Review their medicine diaries

-Discuss symptoms

-Have a tumor sample taken

Participants will be asked to allow their samples and test results to be stored confidentially.

When they stop taking the study drugs, participants will repeat most screening tests. They will be contacted every few months to check on their disease.

Inclusion of Children, Women and Minorities:

Men, women, children (as applicable) and members of all ethnic and racial groups are eligible for this trial.

Subjects of both genders and from all racial and ethnic groups are eligible for this trial if they meet the eligibility criteria outlined in Section 3.1. No groups are being excluded from participation in the trial. Approximately 50% of MPNST develop in individuals with NF1, and we expect that approximately 50% of individuals enrolled will have NF1 associated MPNST and 50% will have sporadic MPNST.

The treatment approach to MPNST is similar for children and adults. Approved adult and adolescent drug dosing was determined to be equivalent in approximately 95% of all products with an adolescent indication studied under the FDA amendments act of 2007. Whereas sporadic MPNST are typically diagnosed in late adulthood, MPNST

diagnosis peaks at a younger age in patients with NF1, generally in early adulthood (20-50 years) with 10-20% of cases reported at event younger ages (1-19 years). Thus, treating patients with greater than or equal to 12 years of age will allow for the majority of patients with MPNST without affecting safety and dosing per FDA findings.
