- Proportion of Patients in Each Arm Who Complete 2 Cycles of Protocol Treatment and Initiate Cycle 3 [ Time Frame: At 8 weeks ]Fisher exact test will be used to detect a difference course 3 between arms (starting low dose [pooled arm A1 and A2] versus [vs.] standard dose [pooled arm B1 and B2]). The proportion of patients who complete 2 courses of protocol treatment and initiate course 3 will be computed by arm with its 95% confidence interval using exact method.
- Overall Survival (OS) [ Time Frame: Time from randomization to death due to any cause, assessed up to 2 years ]OS is defined as the time from randomization to death due to any cause and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.
- Progression Free Survival (PFS) [ Time Frame: Time from randomization to the earlier of disease progression or death due to any cause, where progressed disease (PD) is defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, assessed up to 2 years ]PFS is defined as the time from randomization to the earlier of disease progression or death due to any cause, where progressed disease (PD) is defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.
- Time to Progression (TTP) [ Time Frame: Time from randomization to disease progression, where PD is defined by RECIST 1.1, assessed up to 2 years ]TTP is defined as the time from randomization to disease progression, where PD is defined by RECIST 1.1 and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.
- Cumulative (Total) Dose of Regorafenib Received by Patients in the First Two Cycles [ Time Frame: Up to 8 weeks ]Will be summarized with descriptive statistics and compared between regorafenib arms (A vs. B).
- Dose Intensity of Regorafenib Received by Patients in the First Two Cycles as Measured by the Percentage of Planned Dose Received [ Time Frame: Up to 8 weeks ]Dose intensity of regorafenib received by patients in the first two cycles as measured by the percentage (%) of planned dose received
- Proportion of Patients Overall and Within Each Arm Experiencing Grade 3 or 4 Hand and Foot Syndrome (HFS) or Fatigue [ Time Frame: Up to 2 years ]Will be computed with 95% confidence intervals, and differences between regorafenib dosing strategies (pooled across HFS strategies) tested using a Fisher Exact test. The incidence of grade 3 or 4 HFS will also be descriptively compared between those receiving a pre-specified preemptive vs. reactive approach for hand and foot syndrome (pooled across dosing strategies), and tested using a Fisher Exact test.
- Changes in Quality of Life (QOL) (According to the HFS14 Questionnaire) [ Time Frame: Baseline to up to 8 weeks ]Patients will be descriptively compared between treatment arms and between HFS treatment strategies (pre-emptive vs. reactive) according to self-reported outcomes given on the HFS14 questionnaire. Results from the course 1 and 2 HSF14 questionnaires will also be summarized descriptively as they relate to the pre-emptive versus reactive palmar-plantar erythrodysesthesia syndrome (PPES) strategies, with comparisons made within and between arms using the t-test or Wilcoxon rank sum test as appropriate, as well as taking time-dependence into account.
- Changes in QOL (According to the Linear Analogue Self-Assessment [LASA] Questionnaire) [ Time Frame: Baseline to 8 weeks ]Changes in QOL (according to the LASA questionnaire as measured by the overall QOL question) from baseline will be compared between the treatment arms using the Kruskal-Wallis test.
- Pharmacokinetics (PK) Parameters of Regorafenib Using Liquid Chromatography Mass Spectrometry [ Time Frame: Baseline, prior to treatment, days 7, 14, and 21 prior to treatment (course 1), and days 1 and 21 prior to treatment (course 2) ]After quantitation, the average trough concentration, calculated from all available data, will be calculated. This average trough concentration will be correlated with toxicity and efficacy endpoints. Further descriptive characteristics of the pharmacokinetics will also be calculated, an example includes (but is not limited to) within-patient variability in the trough concentrations pharmacokinetic parameters will also be calculated, both overall and within courses, as a ratio of the maximum:minimum value.
