Clinical Trial Summary

This is a trial for patients affected by metastatic or relapsed osteosarcoma which progressed after first or further line treatments. In this trial, all patients will be treated until progression or unacceptable toxicity with sorafenib and everolimus. The treatment with sorafenib and everolimus aimed to obtain a 50% rate of patients free from further progression of the disease after 6 months from study entry.

Description:

Patients affected by metastatic or relapsed osteosarcoma which progressed after first or further line treatments still have a poor outcome. Standard chemotherapy has limited activity in these patients.

In a previous study in patient affected by relapsed unresectable osteosarcoma, sorafenib alone demonstrated promising activity. In the preclinical setting, everolimus was able to improve the activity of sorafenib. Sorafenib and everolimus, by hitting crucial pathways which are essential for osteosarcoma cell proliferation and survival, with an entirely different approach aimed to overcome the resistance to standard chemotherapy showed by relapsed osteosarcoma. In this trial, all patients will be treated with sorafenib and everolimus at the dosage of 800 mg and 5 mg per day, respectively. Both drugs have to be taken orally. The treatment will be continued until progression or unacceptable toxicities. The objective of the present trial is to obtain a 50% rate of patients alive and free from progression of their disease 6 months after trial enrolment. The disease will be evaluated every 2 months with a CT scan.

Intervention

Drug:
• Sorafenib
Sorafenib tablet 200 milligrams packed in bottle containing 140 tablets. Sorafenib will be administered orally twice daily at the same time every day. Two 200 mg tablets will be taken either one hour before or two hours after a meal followed by a glass of water in the morning and in the evening. In general, patient should have a low to moderate fat meal. Patients will receive Sorafenib until progression, toxicity, withdrawal of informed consent or clinical investigator decision
• Everolimus
Everolimus is formulated in tablets of 2.5 or 5 mg strength, blister-packed under aluminum foil in units of 10 tablets. Everolimus will be administered orally once daily at the same time every day immediately after a meal, as a single dose of 5 mg. Patients should have a low-fat breakfast. After this light meal, study medication of Everolimus is to be taken. The tablets of Everolimus should not be chewed or crushed. Patients will receive Everolimus until progression, toxicity, withdrawal of informed consent or clinical investigator decision
