A study on the TRK inhibitor Larotrectinib in children with advanced solid or primary tumors of the central nervous system
Zusammenfassung der Studie
This is an international study conducted in several countries in North America, Europe, and other parts of the world. The study is being conducted to find out whether Larotrectinib is safe in children and to determine how well their cancer responds to treatment with Larotrectinib. The study has two phases: 1. In phase 1 of the study, called dose escalation, a total of 24 patients were enrolled. Based on the data for the patients enrolled in the dose escalation part of the study, it was determined that enrollment in the dose escalation should be stopped and that all patients in the study should receive Larotrectinib at a dose of 100 mg/m2 twice daily, with the dose of 100 mg twice daily not to be exceeded in any case. In phase 1 of the study, there is also a so-called expansion cohort. Up to 18 children may be enrolled in the expansion cohort. 2. In phase 2 of the study, up to 50 patients may be enrolled. In this phase, there will be three cohorts (patient groups), depending on the type of cancer: infantile fibrosarcoma (10-20 patients), solid tumors (10-20 patients), and central nervous system tumors (10 patients). The study is expected to last about 24 months.

Untersuchte Intervention
Treatment with the study medication Larotrectinib occurs in cycles of 28 days. During each cycle, the patient takes Larotrectinib twice daily as a capsule or solution. In each cycle, the patient is evaluated to assess how the cancer is progressing and how the patient is feeling. Among other things, images of the tumor are taken (using computed tomography or magnetic resonance imaging), blood and urine are collected and analyzed, and questionnaires are completed.

Untersuchte Krankheit(en)
The study examines certain types of cancer in children and young adults aged up to 21 years. Three patient cohorts (patient groups) with NTRK fusions will participate in the study. Patients with infantile fibrosarcoma (IFS), patients with solid tumors, and patients with central nervous system tumors (brain). An NTRK fusion is a change (alteration) in a specific gene (NTRK1, NTRK2, or NTRK3) in a patient's tumor. Larotrectinib is an investigational (or experimental) drug that inhibits the effects of NTRK fusion genes in cancer cells and may be beneficial in treating cancer.

Phase 1: From birth to 21 years at Z1T1 (cycle 1, day 1) with locally advanced or metastatic solid tumor or primary CNS tumor that has not responded to available therapies or has recurred or progressed and for which there is no standard or available systemic curative therapy or: Children from birth with diagnosed malignant disease and documented NTRK fusion that has not responded to available therapies or has progressed and for which there is no standard or available systemic curative therapy or: Patients with locally advanced infantile fibrosarcoma, for whom the investigator believes that a disfiguring surgery or limb amputation would be necessary to achieve complete surgical resection. Enrollment of patients in phase 1 dose escalation is complete. Phase 1 dose expansion: In addition to the above inclusion criteria, patients who are eligible for enrollment in this cohort must have a malignant disease with a documented NTRK gene fusion, except for patients with IFS (Infantile Fibrosarcoma), CMN (Congenital Mesoblastic Nephroma), or SBC (Secretory Burkitt Lymphoma). Patients with IFS, CMN, or SBC may be included in this cohort with a documented rearrangement of the ETV6 gene or a documented NTRK gene fusion. Phase 2: Children from birth at Z1T1 with locally advanced or metastatic infantile fibrosarcoma, patients with locally advanced infantile fibrosarcoma, for whom the investigator believes that a disfiguring surgery or limb amputation would be necessary to achieve complete surgical resection, or: From birth to 21 years at Z1T1 with locally advanced or metastatic solid tumor or primary CNS tumor that has not responded to available therapies or has recurred or progressed and for which there is no standard or available systemic curative therapy. The tumor must have a documented NTRK fusion or, in the case of IFS, CMN, or SBC, patients must have a documented rearrangement of the ETV6 gene or a documented NTRK gene fusion. Patients with benign tumors with NTRK gene fusion are also eligible. or: (including expansion phase) Potential patients over 21 years with a diagnosis of a tumor that has a histology typical of pediatric patients and an NTRK fusion may be considered for enrollment after discussion between the investigator at the local trial center and the medical monitor of the sponsor.

Ausschlusskriterien
Patients meeting the following criteria will be excluded from participation in the study: 1. Major surgery within the last 14 days (2 weeks) prior to Z1T1. 2. Clinically significant active cardiovascular disease or history of myocardial infarction in the last 6 months prior to Z1T1, existing cardiomyopathy, or currently prolonged heart contraction duration (corrected QT interval (QTc) > 480 milliseconds) 3. Active uncontrolled systemic bacterial, viral, or fungal infection. (BASEC)
