Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the trial is to determine whether “optimal exposure” to regorafenib based on plasma concentration of the drug and its metabolites can improve overall survival in mCRC patients.;Secondary Objective: To compare between patients with “optimal exposure” versus patients with “non optimal exposure” to regorafenib: 1.the overall survival at 10 months 2.the objective response to treatment 3.the disease control to treatment 4.the time to progression 5.the safety profile of regorafenib To described: 6.the number of patients with “optimal exposure” at each cycle (C1 and C2) To assessed: 7.the prognostic value on overall survival of the accumulation ratio of plasma concentration of M-2 C2/C1 8.the impact of genetic polymorphisms involved in drug metabolism on the pharmacokinetic of regorafenib and its metabolites 9.study the relationships between body composition (sarcopenia and surface of visceral fat) and oa) early toxicities and efficacy of regorafenib and ob) trough blood concentrations of regorafenib 10.the influence of plasma metabolomics biomarkers on regorafenib response;Primary end point(s): The primary endpoint is the overall survival defined as the time from inclusion to death from any cause. Two groups of patients will be defined a posteriori based on trough concentration of regorafenib and active metabolites: •Group with “optimal exposure”: Csum on C1 and/or Csum on C2 within the range [2.5 – 5.5 mg/L]. •Group with “non optimal exposure”: Csum on C1 and Csum on C2 outside the range [2.5 – 5.5 mg/L]. Csum is defined – for each cycle – as the sum of plasma trough concentrations of regorafenib, M-2 and M-5 at steady state of each cycle. The steady state occurs at the latest at D15 of each cycle. So Csum could be measured in a range of 3 days post-D15 (D15-D18). ;Timepoint(s) of evaluation of this end point: 12 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): They include: 1. 10-month survival rate (defined as the percentage of patients alive 10 months after inclusion) 2. Objective response Rate (ORR) according to RECIST 1.1 and assessed by the investigators. ORR is be defined as the rate of patients with complete or partial response, 3. Disease Control Rate (DCR) according to RECIST 1.1 and assessed by the investigators. DCR is defined as the rate of patients with complete response, partial response or stable disease, 4. Progression-free survival (PFS) according to RECIST 1.1, assessed by the investigators. PFS is defined as the time from inclusion to date of first observed disease progression (radiological or clinical) or death due to any cause, if death occurs before progression is documented. The actual date that the tumor scan was performed will be used for this calculation. PFS for patients without disease progression or death at the time of analysis will be censored at the last date of tumor evaluation. 5. Percentage of patients with significant toxicities (= grade 3). AEs will be assessed from inclusion to 30 day after the discontinuation of the study drug and classified according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. 6. Percentage of patients with “optimal exposure” – i.e. with Csum at D15 within the range [2.5 – 5.5 mg/L]) – at cycle 1 and cycle 2 7. Overall survival for the half of patients with a low ratio of plasma concentration of M2 C2/C1 compared to the overall survival for the half of patients with a high ratio of plasma concentration of M2 C2/C1 8. Genetic polymorphisms in gene involved in regorafenib metabolism and plasma concentrations of regorafenib and its metabolites 9. Body composition will be determined on Computerized Tomography scan (CT-scan) imaging done at baseline and for tumor response evaluation during treatment. One axial image at the 3rd lumbar vertebra will selected for analysis of total muscle | — |
