DOD $1.3M award will launch clinical trial to treat sarcoma

MPNST is a type of cancer called a sarcoma.

The Department of Defense (DOD) awarded Children’s National Hospital $1.3M to launch a unique clinical trial. The trial will evaluate the safety of a novel drug for patients with a rare but aggressive cancer known as malignant peripheral nerve sheath tumors (MPNST).

MPNST is a type of cancer called a sarcoma. While rare in the general population, about half of all MPNST are diagnosed in people with Neurofibromatosis Type 1 (NF1), a condition characterized by changes in skin coloring.

“MPNST is a life-threatening cancer for which there are no adequate medical options,” said AeRang Kim, M.D., Ph.D., director of clinical research of the Division of Oncology at Children’s National. “With the support of this grant, we will conduct a clinical trial to identify effective agents that could be of great benefit to all patients with NF1 who are at risk for sarcoma.”

MPNST are aggressive and frequently metastasize. The tumors that are not able to be removed with surgery rapidly progress and become lethal. In people with NF1, MPNST often develops within benign tumors, especially atypical benign tumors.

The hold-up in the field

Scientists have been looking at the cell signaling process within both pre-cancerous tumors and cancerous MPNST. Previous research has shown that the MEK and MDM2 signaling pathway influence the development and growth of these tumors. By blocking this interplay, the Zhu Laboratory at Children’s National has demonstrated that tumors can get smaller when treated with drugs that inhibit MEK and MDM2 in pre-clinical models.

What’s unique

The trial is uniquely designed to evaluate target inhibition of novel drugs by looking at signals that may help in determining tumor response. This work will provide people with NF1 and MPNST potentially helpful treatments and increase the knowledge for all people with NF1 and those at risk of MPNST. The drugs will be available to all patients who enroll to the study.

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 principal 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.
