Based on preclinical studies of an investigational drug to treat peripheral nerve tumors, researchers at Children’s Hospital of Philadelphia (CHOP) as part of the Neurofibromatosis Clinical Trials Consortium have shown that the drug, cabozantinib, reduces tumor volume and pain in patients with the genetic disorder neurofibromatosis type 1 (NF1). The results of the Phase 2 clinical trial, co-chaired by Michael J. Fisher, MD at CHOP, were published recently in Nature Medicine.
