Phase I Trial of TURALIO (Pexidartinib, PLX3397) in Children and Young Adults With Refractory Leukemias and Refractory Solid Tumors Including Neurofibromatosis Type 1 (NF1) Associated Plexiform Neurofibromas (PN) and Tenosynovial Giant Cell Tumor (TGCT)
National Cancer Institute (NCI)
Summary
Background: \- Some people with cancer have solid tumors. Others have refractory leukemia. This may not go away after treatment. Researchers want to see if a drug called TURALIO(R) can shrink tumors or stop them from growing. Objectives: \- To find the highest safe dose and side effects of TURALIO(R). To see if it helps treat certain types of cancer. Eligibility: \- People ages 3-35 with a solid tumor or leukemia that has returned or not responded to cancer therapies. Design: * Individuals will be screened with: * Medical history * Physical exam * Blood and urine tests * Heart tests * Scans or other tests of the tumor * Individuals will take TURALIO(R) as a capsule once daily for a 28-day cycle. They can do this for up to 2 years. * During the study, participants will have many tests and procedures. They include repeats of the screening tests. Individuals will keep a diary of symptoms. * Individuals with solid tumors will have scans or x-rays. * Individuals with leukemia will have blood tests. They may have a bone marrow sample taken. * Some individuals may have a biopsy. * When finished taking TURALIO(R), individuals will have follow-up visits. They will repeat the screening tests and note side effects.
Description
Background * Traditional therapeutic approaches to pediatric cancer have focused on cytotoxic agents and, more recently, targeted inhibition of cellular signaling pathways through the use of small molecule kinase inhibitors. Despite these interventions, significant numbers of pediatric cancer patients develop recurrent and resistant disease. Targeting the tumor microenvironment is a promising but incompletely explored strategy for the treatment of pediatric cancer and non-cancer tumors. * This trial will begin to explore the disruption of the interaction between neoplastic cells and the myelo…

* INCLUSION CRITERIA: * Diagnosis: * Individuals must have recurrent or refractory solid tumors or acute leukemia (limited to AML or ALL) or have been intolerant of prior therapies, confirmed by the Laboratory of Pathology, NCI, e.g., solid tumors including rhabdomyosarcoma, Ewing sarcoma, soft tissue sarcomas. These may include primary neoplasms of the central nervous system, such as high-grade (WHO grade III-IV) glioma. Individuals with diffuse intrinsic pontine glioma (DIPG) or optic pathway glioma are exempt from histologic verification. For DIPG typical MRI findings must be present whi…
