简要总结
This is a multicenter phase II study concerning patients with high-grade bone sarcoma (HGBS) without complete remission after standard treatment at diagnosis or at relapse.
Patients will be treated with regorafenib + best supportive care (BSC) for a maximum of 12 months as maintenance therapy after standard line therapy completion.
Progression free rate (PFR) data will be collected and analysed for all included patients to evaluate if regorafenib + BSC can be considered as an interesting treatment for further investigations in this indication.
详细描述
This is a multicenter phase II study.
Patients with evaluable unresectable residual disease will be accrued after they completed standard of care, consisting of:
- At diagnosis: standard multimodal treatment based on histological subtype
- At relapse: chemotherapy
Patients who meet the eligibility criteria will receive regorafenib + best supportive care (BSC) as maintenance treatment for a maximum 12 months period.
After their eligibility has been confirmed, patients will receive regorafenib until disease progression, or for a maximum of 12 months, or unacceptable toxicity or willingness to stop, whichever occurs first.

In case of toxicity, dose can be reduced or treatment interrupted according to Specific Product Characteristics (SPC).
Patients can receive up to a maximum of 13 cycles (maximum treatment period : 12 Months).
干预措施: Treatment by regorafenib and best supportive care (Drug)
结局指标
主要结局
Progression-Free Rate at 4 months (4m-PFR)
时间窗: Up to 16 weeks after the date of regorafenib + BSC treatment initiation
The Progression-Free Rate at 4 months (4m-PFR) will be defined as the proportion of patients with a complete response, a partial response or stable disease, confirmed on tumour assessments according to the RECIST V1.1 at 4 months (16 weeks) after the date of regorafenib + BSC treatment initiation. Patients with a non-progressive disease at 16 ± 2 weeks after the date of regorafenib + BSC treatment initiation will be considered as "success" patients. Patients with a progressive disease and patients who died from any cause at 16 ± 2 weeks after the date of regorafenib + BSC treatment initiation will be considered as "failure" patients. At the time of analysis, if at least 18 "successes" are observed among the 36 analyzed patients, the regorafenib + BSC treatment will be considered as interesting for further investigations in this indication.
次要结局
- Progression-Free Survival (PFS)(Up to 3 years)
- Objective Response Rate (ORR)(Up to 3 years)
- Disease Control Rate (DCR) at 2 months(2 months)
