Detailed Description

1. Patient registration procedure

   If it is confirmed that the subject meets the inclusion criteria and correspondent none of the exclusion criteria, the subject is registered by using Clinical Research Support Center (CReS) Kyushu registration/allocation system. The registration with the registration/allocation system is available for 24 hr (URL: https://reg.cres-kyushu.or.jp/qmin/login/) and needs for individual identifier (ID) and password.

2. Quality management

   • Preparation and management of the test drugs

The test drugs are an active drug, which is a capsule filled with dexamethasone powder and lactose, and a placebo, which is a capsule filled with only lactose. The test drugs will be prepared by the Department of Pharmacy (manager: Professor Masuda), Kyushu University Hospital in accordance with the procedures for preparation of the test drugs. Dexamethasone powder and lactose will be purchased by Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University from Tomita Pharmaceutical and delivered to the pharmacy department. Research funds will be used for the purchase. The capsule will be purchased from Tomita Pharmaceutical. The test drugs will be delivered to CReS-Kyushu (enrollment/data center) and managed using a double-blind method in accordance with the procedures. The double-blind code will be kept by the person responsible for management of the test drugs Shoji Tokunaga, Medical Information Center, Kyushu University, and a backup of the code will be kept by Hidekazu Aratani of CReS-Kyushu.

The test drugs will be managed according to the investigational drug number and stored at the warehouse of the Fukuoka branch of Yamato Logistics Co., Ltd. The warehouse is certified to store drugs for humans for more than 2 years under the supervision of pharmacists.

In the participating medical institution, manager and vice manager for the management of the test drugs will be appointed. It is preferable that the manager and vice managers are selected from among personnel who are experienced in drug management including personnel from the Department of Pharmacy or clinical trial management office. The manager is not allowed to become the investigator or sub-investigator. A physician who may treat subjects is not allowed to become the manager.

The electronic data capture (EDC) system will be used for communications between the enrollment/data center, Yamato Logistics and participating medical institution. Information on subjects will be reported by e-mail to the data center, and the data center will ensure the information by telephone to Yamato Logistics and the investigational drug management division of the medical institution. The test drugs will be delivered by Yamato Logistics to the medical institution. The test drugs for only a subject will be delivered once (allocation adjustment factor). Considering that a number of days are necessary for delivery, there should be at least 3 working days between enrollment and start of treatment. The interval between enrollment and start of treatments should be up to 14 days. Physicians treating subjects are not allowed to manage the test drugs. The vice manager will manage the test drugs according to subjects under the supervision of the manager. Orders for the test drugs will be made by letter or e-mail in accordance with the medical institution's procedures. A sufficient number of capsules of the test drugs until the next hospital visit will be ordered/prescribed once. If the test drugs are used properly in accordance with the protocol, an order/prescription for the test drugs will be made every 7 days. Subjects (patients) will be advised to keep records of the use of regorafenib and test drugs in the medication diary. The remaining number of capsules of the test drugs will be checked in consideration of the use of the test drugs. The remaining test drugs will be returned to the study office. In accordance with the protocol, the test drugs should be prescribed for 28-day treatment, but will be prescribed for 30-day treatment considering loss and damage. The test drug for 2-day treatment should be left unused when treatment is completed. The remaining test drugs will be returned to the enrollment/data center.

When the test drugs are delivered, the enrollment number, investigational drug number, reception date, the number of capsules of the test drugs delivered will be entered in the EDC system. Also, the number of capsules prescribed, date of prescription, remaining number of capsules (total number of capsules stored including the number of capsules returned), confirmation date of completion/discontinuation of the protocol treatment, total remaining number of capsules including the number of capsules returned will be entered in the EDC system.

The number of capsules lost and reasons for the loss will be entered in the EDC system.

• Monitoring

A central monitoring or in-site monitoring are carried out based on the data from case report form (CRF) collecting at data coordinating center. In principle, an on-site monitoring is not carried out, but it may be carried out when the on-site monitoring is determined to need by Kyushu Study group of Clinical Cancer (KSCC) steering committee from the results of the central monitoring so on.

Data Monitoring Committee A Data Monitoring Committee (DMC) has been established.

• Data entry

all data will be entered by the double entry method. Referential data rules, valid values, range checks, and consistency checks against data already stored in the database will be supported. Checks will be applied at the time of data entry into a specific field. Additional errors will be detected by programs designed to detect missing data or specific errors in the data. The investigator who receives the inquiry will respond by checking the original forms for inconsistency, checking other sources to determine the correction, modifying the original paper form entering a response to the query.

• Regular monitoring report

A regular monitoring report generated by data coordinating center is submitted to KSCC Steering Committee, principal investigator, the DMC etc and it is reviewed according to "KSCC regulation on the monitoring". The information on the status of site ethics committee (EC) approval and the achievement of enrollment: number of enrollment- total/per periodical, total/per site, is reported monthly using e-mail.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
incidence of fatigue or malaise (CTCAE ver. 4, all grades)	With the number of subjects in safety analysis set (SAS) as the denominator, the frequency of the worst grade of "fatigue" or "malaise"(according to CTCAE ver.4.0) is determined.	4weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
brief fatigue inventory （Patient Reported Outcome）	For all subjects enrolled in the present clinical study, the severity of fatigue/malaise is rated using the brief fatigue inventory (BFI) scale obtained every week following the start. Mean of numerical evaluating scale from 9 questions is defined as the global fatigue score. Details of the method to collect and analyze the BFI as a patient reported outcome (PRO) will be specified in a procedure separately prepared along the instruction by Professor Yamaguchi (Tohoku University).	4weeks
adverse events	With the number of subjects in whom at least a part of the protocol treatment is provided (all treated subjects) set as the denominator, the frequencies of the following adverse events/toxicity (according to CTCAE ver.4.0) appearing at the worst grade whenever during the entire treatment course are determined by treatment group. Whether ineligible subjects are included in the analysis set or not is decided by the KSCC's research administration office through discussion with the Registration/Data Center. With the number of subjects in Full analysis set (FAS) set as the denominator, the rate of treatment discontinuation due to adverse events other than disease progression is determined.	1year
relative dose intensity (regorafenib)	With the planned dose of regorafenib in 1 course set as the denominator while the actual dose set as the numerator, the relative dose intensity (given in percentage) is determined for the FAS.	4weeks

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
medicine taking situation (regorafenib, study drug)		4weeks (study drug), 1year (regorafenib)
response rate	The best response rate based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 is defined as the proportion of subjects (among the FAS) whose best overall response is either complete response (CR) or partial response (PR).	1year
disease control rate (DCR)	The disease control rate is defined as the proportion of subjects (among the FAS) whose best overall response and confirmed overall response based on RECIST v1.1 are either of CR, PR, or stable disease (SD).	1year
treatment continuation period		1year
progression-free survival (PFS)	For the FAS, the progression-free survival is defined as a period from the day of enrollment to whichever earlier date of exacerbation or death from any cause.	1year
overall survival (OS)	Taking the enrollment day as the starting date, the overall survival is defined as time to death for any cause. Subjects who are alive are censored for over survival at the date that they are last known to be alive. Subjects who lost to follow-up are censored for overall survival at the date that they are last known to be alive.	1year
