Clinical Trial Summary

The aim of the project is to improve treatment outcomes in patients with primary malignant bone tumors, refractory to standard therapy, by increasing the availability of advanced therapy, as well as to develop treatment options using advanced molecular diagnostics for patients who have not responded to the standard therapeutic regimen, and to introduce modern diagnostics for risk stratification and for the use in molecularly targeted therapies.


Description:

The scope of the project is to cover the entire population of children, adolescents and young adults from the age of 9 to the age of 21, who progressed to first-line treatment or who presented with a recurrence of Ewing's sarcoma or osteosarcoma. Despite escalating doses of chemotherapy and radiotherapy, aggressive surgical procedures in patients with dissemination disease and negative prognostic factors, no improvement in treatment outcomes has been achieved for over 30 years. For this reason, other therapeutic options are being investigated. There have been no significant responses to immunotherapy. Although, the inclusion of tyrosine kinase inhibitors (TKIs) appears to be promising. The identification of new mutations in bone tumors has led to a better insight into the molecular basis of these tumors, which has resulted in a more significant role of genetic research in everyday practice. Although traditional histopathological examinations are currently the basis for the diagnosis of bone tumors, the developing techniques of molecular biology make it possible, in many cases, to refine the diagnosis and, in the near future, will become the basis for the classification of these neoplasms. Moreover, these technics are expected to enable the qualification of patients to modern molecularly targeted therapies. Based on the above data, the objectives of the project are as follows: 1. to estimate the nature and frequency of mutations in the tumor tissue, 2. to compare molecular test results with clinical data (which will allow for the initial assessment of the impact of the mutation status on the clinical condition, course of treatment and prognosis), 3. to include targeted treatment - broad spectrum tyrosine kinase inhibitor - regorafenib in standard therapy.

Patients with heart defects and / or cardiac arrhythmias requiring permanent treatment with antiarrhythmic drugs. 11. Other acute or persistent disorders, behaviors or abnormal laboratory test results, which might increase the risk related to the participation in this clinical trial or to taking the study drug, or which might influence the interpretation of the study results, or which, in the investigator's opinion, disqualify a patient from participating in the trial.

Study Design


Intervention

Drug:
Regorafenib
Patients will receive regorafenib orally at doses adjusted for age, body surface area and pharmacokinetics. Treatment with regorafenib will be continued for up to 1 year or until disease progression, patient death, unacceptable toxicity, or study closure. Pharmacokinetics and safety profile of the investigational product (IP) will be determined throughout the course therapy. In the event of progression or relapse, patients in the control group will have the option to receive the IP along with the standard treatment of the next line.
