Clinical Trial Spotlight: Searching for effective therapies for malignant peripheral nerve sheath tumors

Malignant peripheral nerve sheath tumors

Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas and the most common malignancy associated with neurofibromatosis type 1 (NF1).

Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas and the most common malignancy associated with neurofibromatosis type 1 (NF1). Half of all MPNST are seen in NF1 patients, and MPNST is a leading cause of mortality in young patients with NF1. Researchers led by AeRang Kim, M.D., Ph.D., a pediatric oncologist at Children’s National Hospital, are now searching for a medical treatment for this rare disease that currently has dismal survival rates.

“Through consortia efforts, we’ve been able to open and accrue in single histology trials of really rare diseases such as MPNST for which there are no known curative therapies other than surgery, and surgery is very difficult or not feasible in many patients,” says Dr. Kim, the principle investigator for the SARC031 trial sponsored by the Sarcoma Alliance for Research through Collaboration. “In this trial in particular, our hope is to find a new therapy that will benefit patients with MPNST for which we have no known effective medical therapies.”

Using a combination of drugs that target specific pathways involved in MPNST growth, Dr. Kim and colleagues at four other institutions offering the SARC031 trial will monitor patients to see if the drugs shrink, slow down or stop the growth of MPNSTs. Based on preclinical data demonstrating substantial MPNST shrinkage in mice treated with a combination of MEK and mTOR inhibitors, SARC031 is a trial of the MEK inhibitor selumetinib in combination with the mTOR inhibitor sirolimus for patients with unresectable or metastatic MPNST. The primary objective is to determine the clinical benefit of the combination.
