E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal objective of the trial is to investigate the antitumor activity of regorafenib in terms of progression Free Survival (PFS) according to modified RECIST (RECIST 1.1) after central radiological review. |
|
E.2.2 | Secondary objectives of the trial |
1. Objective response rate [defined as complete response (CR) or partial response according to RECIST 2009, version 1.1] ;
2. Disease control rate at 6 months (defined as the proportion of patients who a best response rating of CR, PR or stable disease [SD]), SD should be at least 8 weeks ;
3. Overall survival (defined as the time from the date of randomization until the date of death due to any cause); if the patients is alive at the date of data base cut off then he will be censored at the data base cut off date;
4.Duration of response (defined as the time from date of first documented objective response of CR or PR, whichever is noted earlier, to first disease progression or death before progression ;
|
5. Progression-free rate at 3 and 6 months (PFR-3 and PFR-6), defined as the proportion of patients without progression at 3 and 6 months post randomization;
6. Time to progression (measured from date of randomization until the date of first observation of progression );
7. Growth Modulation Index defined as ratio of time to PD under regorafenib to TTP under previous treatment. The GMI will be explored in patients receiving regarafenib after randomization.
8. Identification and characterization of biomarkers
Toxicity according to NCI-CTC V4.0. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacogenomic study that the objectives are :
• Identification and characterization of biomarkers: protein expression signature that can potentially be used as predictive markers of response to regorafinib.
• Better definition of the patient population most sensitive to regorafinib.
|

E.3 | Principal inclusion criteria |
1. Patients must have histologically confirmed diagnosis of bone sarcoma (osteosarcoma, Ewing sarcoma of bone, chondrosarcoma) with available Formalin Fixed Paraffin Embedded (FFPE) blocks obtained for centralized review;
2. Patients with confirmed disease progression at study entry. The “baseline” radiological evaluation should demonstrate disease progression by RECIST V 1.1 when compared to a prior disease assessment done within a prior period of 3 month for osteosarcoma and Ewing sarcomas and within 6 month period for chondrosarcomas prior to screening
Note: radiographic progression of disease will be based on at least 2 sets of scans (either MRI or CT) in the 3-month (for osteosarcomas and Ewing sarcoma) or 6-month period for chondrosarcoma prior to or during screening in which radiographic progression of disease , as defined by RECIST , is demonstrated. No central review of scans (either MRIs or CTs) will be required for study eligibility; these scans must be sent for central review within 10 days after randomization;
3. Metastatic disease not amenable to surgical resection or radiation with curative intent;
4. Patients must have measurable disease (outside any previous irradiated field) defined as at least one unidimensionally lesion that can be accurately measured as ≥ 10 mm with CT scan according to RECIST V1.1;
5. Prior treatment :
at least one, but no more than two prior (combination) chemotherapy regimen for metastatic disease; neo-adjuvant /maintenance therapy are not counted towards this requirement. At least 4 weeks since last chemotherapy (6 weeks in case of nitrosoureas and mitomycin C), immunotherapy or any other pharmacological treatment and/or radiotherapy;
6. Age ≥ 18 years;
7. Life expectancy of greater than 3 months;

10. INR/PTT ≤1.5 x ULN;
Patients who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring of at least weekly evaluations will be performed until INR/PTT is stable based on a measurement that is pre-dose as defined by the local standard of care;
11. Recovery to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.0 Grade 0 or 1 level or recovery to baseline preceding the prior treatment from any previous drug/procedure related toxicity (except alopecia, anemia, and hypothyroidism);
