Brief summary
The goal of this study is to determine the response of the study drug loratinib in treating children who are newly diagnosed high-grade glioma with a fusion in ALK or ROS1. It will also evaluate the safety of lorlatinib when given with chemotherapy or after radiation therapy.
Detailed description
This is a multi-institutional clinical trial of lorlatinib in children newly diagnosed with High Grade Glioma (HGG) harboring ROS1 (ROS Proto-Oncogene 1, Receptor Tyrosine Kinase) or ALK (anaplastic lymphoma kinase) fusions. In this pilot study, investigators will assess the disease control rate (Continued Complete Response (CCR), Complete Response (CR), Partial Response (PR), and Stable Disease (SD)) of lorlatinib, and feasibility and safety of lorlatinib administration in combination with standard chemotherapy in children with newly diagnosed HGG with ROS or ALK fusions who receive 2 cycles of lorlatinib administered orally, once daily, at 115 mg/m2/day (or maximum of 200mg/dose) for pediatric patients, and 150mg/dose for patients \>18 years, continuously. Secondary objectives include overall survival (OS) and progression free survival (PFS) lorlatinib as a single agent and in combination with standard chemotherapy used in children ≤ 48 months with HGG, or post focal radiotherapy in children \> 48 months of age. Children with HGG who have a CCR or CR after 2 cycles of therapy will continue to receive single agent lorlatinib for a total of 12xs 28-day cycles. Continuation of treatment beyond 12 cycles, and up to maximum 26 cycles, may be considered for patients on lorlatinib monotherapy if they are receiving clinical benefit from the study, at the discretion of the treating physician after discussion with Study Chairs. Patients with PR or SD after 2 cycles of lorlatinib monotherapy will go on to receive lorlatinib either in combination with standard backbone chemotherapy (BABYPOG or HIT-SKK, investigator's choice) or post standard radiotherapy, based on the patient's age. Patients with PD after 2 cycles will be taken off protocol therapy. This study will be a part of the TarGeT, molecularly-guided umbrealla trial in children, adolescents, and young adults newly diagnosed with HGG, including diffuse intrinsic pontine glioma (DIPG)/diffuse midline glioma (DMG). Patients will undergo (1) upfront comprehensive tumor molecular profiling using multi-omic approach with rapid return of results, (2) stratification to biologically-targeted treatment arms to assess treatment efficacy, and (3) longitudinal evaluation of peripheral blood, cerebrospinal fluid (CSF), and/or tumor tissue as well as neuro-imaging to identify biomarkers predictive of response, recurrence, and resistance. Based on recent trials conducted in this patient population, investigators conservatively estimate that 1 child with newly diagnosed DIPG or HGG with either ROS1 or ALK fusion will be enrolled every 2 months on this study. Patients ≤18 years will start at the recommended phase 2 dose of 115 mg/m2/day and patients \>18 years will start at 150mg/dose. All patients will be treated continuously for 28 days, and one dose de-de-escalations will be allowed. A maximum of 15 eligible patients will be enrolled, anticipated over 2.5 years.

Feasibility
Eligibility
Inclusion criteria
1. Patients must be ≥ 12 months and ≤ 21 years of age at the time of study enrollment on TarGeT-SCR. 2. Diagnosis: Patients with newly diagnosed high-grade glioma (HGG), including diffuse intrinsic pontine gliomas (DIPG), whose tumors harbor an ALK or ROS-1 fusion alteration are eligible. Patients must have had histologically verified high-grade glioma from diagnostic biopsy or resection. For the diagnosis of DIPG, patients must have a tumor with pontine epicenter and diffuse involvement of at least 2/3 of the pons, with histopathology consistent with diffuse WHO Grade 2-4. All other HGGs must be Grade 3 or 4. 3. Disease Status: Patients with disseminated DIPG or HGG are eligible only if the patient is to receive chemotherapy only, i.e. no craniospinal RT is intended to be given. MRI of spine must be performed if disseminated disease is suspected clinically by the treating physicians. Patients with primary spinal tumors are eligible only if the patient is to receive either chemotherapy or focal radiation therapy, i.e., no craniospinal RT is intended to be given. Patients with leptomeningeal disease only, with no definitive identifiable primary tumor, and documented ALK or ROS-1 fusion, must be discussed with the Study Chair on a case-by-case basis. 4. Performance Level: Karnofsky ≥ 50% for patients \> 16 years of age and Lansky ≥ 50 for patients ≤ 16 years of age (See Appendix I). Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score. 5. Prior Therapy: * Patients must not have received any prior anti-cancer chemotherapy. * Prior use of corticosteroids is allowed (see below
Exclusion criteria

Organ Function Requirements 6.1 Adequate Bone Marrow Function Defined as: * Peripheral absolute neutrophil count (ANC) ≥ 1000/μL * Platelet count ≥ 100,000/μL (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment) * Hemoglobin \>8 g/dL (may receive transfusions) 6.2 Adequate Renal Function Defined as: * Serum creatinine within normal institutional limits OR Creatinine clearance or radioisotope GFR ≥ 70ml/min/1.73 m2 6.3 Adequate Liver Function Defined as: * Total bilirubin ≤ 2 × institutional upper limit of normal * AST(aspartate aminotransferase)/ALT(alanine transaminase) ≤ 2.5 × institutional upper limit of normal 6.4 Adequate Pulmonary Function Defined as: Pulse oximetry \> 94% on room air if there is clinical indication for determination (e.g. dyspnea at rest). 6.5Adequate Cardiac Function Defined as: QTc ≤ 470 msec (by Bazett formula) 6.6 Adequate Neurologic Function Defined as: Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled. 6.7 Informed Consent: All patients and/or their parents or legally authorized representatives must sign a written informed consent.
