|---|---|---|---|
| Primary | Objective tumour response (complete or partial response) as determined by RECIST v1.1 | At or before 9 months from the time from either (i) randomization (if patients have not yet commenced treatment) or (ii) commencement of therapy (if patients are randomized during the first cycle of imatinib) | The objective tumour response rate (OTRR) will be calculated by summing the number of participants assessed as having a complete or partial response within the first 9 months from the time from either (i) randomization (if patients have not yet commenced treatment) or (ii) commencement of therapy (if patients are randomized during the first cycle of imatinib), and dividing this by the total number of participants evaluable for response. For patients who undergo surgery, the best response is determined in the time period that precedes the date of surgery. The responses are confirmed at the time of the next scheduled imaging, usually done 8 weeks after the first detection of response, provided that imaging of the target lesions is not indicated sooner than this for other reasons. Both the numbers and the proportions of confirmed and unconfirmed responses will be reported. The minimum duration of SD is defined as 8 weeks. |
| Secondary | Progression free survival at 24 months (disease progression or death) | 24 Months | PFS at 24 months as calculated from the time from either (i) randomization if patients have not yet commenced treatment) or (ii) commencement of therapy (if patients are randomized during the first cycle of imatinib) to the date of progression as determined by RECIST v1.1 |
| Secondary | Clinical benefit rate at 24 weeks | 24 weeks | Clinical benefit rate (SD + PR + CR) following 2 cycles of treatment |
| Secondary | Time to treatment failure | 5 years | Time to treatment failure is defined as the time from either (i) randomization (if patients have not yet commenced treatment) or (ii) commencement of therapy (if patients are randomized during the first cycle of imatinib) to treatment discontinuation for any reason, including disease progression, treatment toxicity, patient preference, or death. |
| Secondary | Adverse Events | 5 years | Safety/toxicity/tolerability |
| Secondary | Overall survival | 5 years | Overall survival is defined as the interval from either (i) randomization (if patients have not yet commenced treatment) or (ii) commencement of therapy (if patients are randomized during the first cycle of imatinib) to date of death from any cause, or the date of last known follow-up alive. |
| Other | Macroscopically complete removal of all residual disease by surgery | 5 years | This is defined as the rate of patients who proceed to surgery with the aim of resecting all remaining macroscopic disease. |
| Other | Change in PET imaging during washout period of regorafenib and imatinib in those taking part in the PET substudy | 3 years | to explore the relationship between change in PET imaging during washout period of regorafenib and imatinib (in subset of participants at selected centres) |
| Other | Imatinib plasma levels 4 and 12 weeks after commencement of treatment in both arms. Arm B: Imatinib plasma levels at 3 and 11 weeks after commencement of treatment and regorafenib plasma levels 7 and 15 weeks after commencement of treatment. | 3 years | To explore the relationship between study endpoints and Imatinib plasma levels at 4 and 12 weeks after commencement of treatment in both arms. Arm B: Imatinib plasma levels at 3 and 11 weeks after commencement of treatment and regorafenib plasma levels 7 and 15 weeks after commencement of treatment. |
| Other | Change in circulating serum/plasma growth factor and cytokine levels over time(multiplex assay), Frequency of KIT/PDGFRA mutations in circulating blood DNA and DNA load as prognostic and/or predictive markers | 3 years | To explore the relationship between study endpoints and circulating other biomarkers as prognostic and/or predictive markers. |
| Other | Tumour tissue biomarkers including, but not limited to, proteins relating to EGFR and PDGFR signalling and angiogenesis. | 3 years | |
| Other | Macroscopically complete removal of all residual disease by surgery | 3 years | Rate of patients having macroscopically complete removal of all residual disease by surgery |
