Phase I Trial of TURALIO(R) (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 ...
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)
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:
- Participants will be screened with:
- Medical history
- Physical exam
- Blood and urine tests
- Heart tests
- Scans or other tests of the tumor
- Participants 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. Participants will keep a diary of symptoms.
- Participants with solid tumors will have scans or x-rays.
- Participants with leukemia will have blood tests. They may have a bone marrow sample taken.
- Some participants may have a biopsy.
- When finished taking TURALIO(R), participants will have follow-up visits. They will repeat the screening tests and note side effects.

Detailed 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 myeloid component of the tumor microenvironment as a treatment strategy for pediatric cancers and neurofibromatosis type 1 (NF1) related plexiform neurofibromas (PN) and malignant peripheral nerve sheath tumor (MPNST).
- TURALIO(R) is an orally available small molecule inhibitor of class III protein tyrosine kinases including Kit, CSF1R (colony stimulating factor 1 receptor)/Fms (Feline McDonough Sarcoma), and oncogenic Flt3 (Fms like tyrosine kinase).
Primary Objectives
-Evaluate the safety and tolerability of TURALIO(R) and determine a recommended phase II dose of TURALIO(R) in pediatric patients with refractory solid tumors including NF1 MPNST and brain tumors or refractory leukemias, limited to acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL).
Eligibility
->= 3 and <= 35 years of age
- Recurrent or refractory solid tumors including primary neoplasms of the central nervous system and patients with NF1 and MPNST, or refractory leukemias (AML or ALL).
- Subjects must have adequate performance status, be able to swallow tablets, may not be pregnant or breastfeeding, and have adequate major organ function. Subjects with history of severe or uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic cardiovascular or pulmonary disease, or history of prolonged QT syndrome will be excluded.
Design
- Using a rolling-six phase I design with 2-6 subjects per dose level and standard definitions of MTD (during cycle 1) and DLT.
- TURALIO(R) will be administered orally (125 mg capsules) once daily on a continuous basis for cycles of 28 days without a rest period between cycles. Patients must be able to swallow intact capsules. Dosing will be based on body surface area (BSA), and the total weekly dose will be rounded to within 10% of calculated dose using a dosing nomogram.
- At the MTD, the recommended phase II dose level will be expanded to up to 12 patients with attempts made to enroll at least 3 patients with refractory solid tumors and 3 patients with refractory acute leukemia (ALL and AML) to gain more experience with the toxicities and pharmacokinetics of TURALIO(R) in these disease cohorts. Attempts will be made to enroll equal numbers of patients between the ages of 3 and 12 years and over 12 years of age to gain pharmacokinetic and safety data over a broad age range.

Description
- INCLUSION CRITERIA:
Diagnosis:
- Patients 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. Patients with diffuse intrinsic pontine glioma (DIPG) or optic pathway glioma are exempt from histologic verification. For DIPG typical MRI findings must be present which include hypo- or isointense on T1-weighted imaging, hyperintense on FLAIR or T2-weighted imaging, epicenter in the pons in the face of a typical clinical presentation. Optic pathway gliomas are located in the optic pathway and are typically hypo- or iso-intense on T1 and hyperintense on T2-weighted images.
In addition, patients with NF1 and with malignant peripheral nerve sheath tumor (MPNST).
- Patients must have relapsed after or be refractory to effective standard therapies. There are no limits on number of prior therapeutic regimens.
- Disease status: Patients with refractory solid tumors including patients with NF1 and MPNST must have evaluable disease, patients with leukemia must have measurable or evaluable disease at the time of enrollment, which may include any evidence of disease including minimal residual disease detected by flow cytometry.
- Age >= 3 and <= 35 years of age (must have BSA >= 0.55 m^2):
- Ability of subject or Legally Authorized Representative [LAR] (the parent/guardian if subject is a minor) to understand and the willingness to sign a written informed consent document.
- Patients must be able to swallow capsules.
- Performance Status: Karnofsky >= 50% for patients > 16 years of age and Lansky >= 50% for patients <= 16 years of age. Subjects who are wheelchair bound because of paralysis will be considered "ambulatory" when they are up in their wheelchair. Subjects have to be able to travel to the NIH for evaluations.
- Prior therapy:
Patients must have fully recovered (to Grade 1) from the acute toxic effects of all prior anti-cancer therapy.
- Myelosuppressive chemotherapy: At least 21 days after the last dose of myelosuppressive chemotherapy (42 days if prior nitrosourea).
- Biologic (anti-neoplastic agent): At least 7 days after the last dose of a biologic agent. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. The duration of this interval must be discussed with the study chair.

- Serum creatinine <= 1.5 x ULN
Exceptions:
- Cytopenias due to underlying disease (i.e. potentially reversible with anti-neoplastic therapy); A subject will not be excluded because of cytopenia due to disease, based on the results of bone marrow studies.

Fertile men must also agree to use an acceptable method of birth control while on study drug and for at least one week after last dose.
