Spots Global Cancer Trial Database for A Study Called EPI VITRAKVI to Compare Treatment Results in Patients With Infantile Fibrosarcoma (IFS), a Type of Connective Soft Tissue Cancer, Who Received a Treatment Called Larotrectinib From a Study Called SCOUT With Patient Data From an External Database

Study Description

Brief Summary: This is an observational study in which data from the past of children and young people with a specific cancer, called NTRK gene fusion positive infantile fibrosarcoma (IFS) is studied. IFS is a rare type of childhood cancer that commonly affects legs and arms. IFS cancers typically have specific changes in their building plans (genes) called NTRK gene fusion. NTRK stands for the specific gene that has been altered, the neurotrophic tyrosine kinase (NTRK) gene. This change to the building plan leads to the creation of an altered protein known as a TRK fusion protein, which can cause cancer cells to grow and to survive. The specific cancer is therefore also called TRK (tropomyosin receptor kinase) fusion-positive IFS. The study drug, larotrectinib (also called BAY2757556) works by blocking the altered TRK fusion protein. Larotrectinib is already available in Europe and in many other countries and is approved for doctors to prescribe to patients with NTRK gene fusion cancer which has spread to nearby tissues and/or lymph nodes or to other parts of the body. In France, HAS (the French authority in charge of evaluating health products and technologies) gave a positive opinion for the reimbursement of larotrectinib but only in the pediatric patients with IFS or another STS harboring a NTRK gene fusion, which is locally advanced or metastatic, and refractory or in relapse mainly due to the lack of comparative evidence. The main purpose of this study is to collect more data to learn how well larotrectinib works compared with current standard of care chemotherapy in people up to 21 years of age with NTRK gene fusion positive IFS that has spread to nearby tissues and/or lymph nodes (locally advanced) or other parts of the body (metastatic). To see how well larotrectinib works, researchers will make a comparison between * how long larotrectinib works well and * how long the standard of care works well. Working well means that the treatments can prevent the following from happening: * need for a new treatment for the cancer * need for radiation therapy for the cancer * need for surgery to treat the cancer, but which causes major damage to body parts * death. In addition to the above, data about medical problems related to the treatments in both groups and that may have required to stop the treatment will be compared. The data for the comparison will come from * an ongoing international study called SCOUT which was started in December 2015 (larotrectinib group) * international databases (standard of care chemotherapy group). Data will be from the year 2000 up to the present. There will be no required visits with a study doctor or required tests in this study.
