Brief Summary

the efficacy and safety ofhe use of regorafenib in combination with nivolumab

Detailed Description

The present trial consists of a dose-escalation cohort to verify the tolerability of nivolumab and regorafenib when used in combination for patients with solid tumors, and to examine the clinical recommended dose(RD). The trial also consists of an expansion cohort to examine the safety and efficacy when the clinical RD is administered for several advanced solid tumors.

In the dose-escalation cohort, three patients with solid tumors will be administered 3.0 mg/kg of nivolumab once every 2 weeks and regorafenib daily for 21days, with a 1-week washout period at dose of 80 mg (level 1), 120 mg (level 2), or 160 mg (level 3). As a general rule, one cycle will last 28 days (day 1-29); however, in the event of treatment prolongation, the cycle period will be extended. The Dose Limiting Toxicity(DLT) evaluation period will be 28 days. Furthermore, for each level, three additional subjects will be added depending on the state of DLT.

In the expansion cohort, the target subject sample will consist of approximately 30 patients who will be administered 3.0 mg/kg of nivolumab once every 2 weeks, and the clinical RD of regorafenib will be determined in the dose-escalation cohort.

Study Groups

Level 1

Regorafenib: Oral administration at a dose of 80 mg given once per day for 21 consecutive days, with a 1-week washout period.

Nivolumab: Given once every 2 weeks at a dose of 3.0 mg/kg via an intravenous infusion.

When it is deemed that there is no problem with safety at the doses described above, tolerability will be verified at the level-2 dosages described below.

Group Type: ACTIVE_COMPARATOR

Regorafenib

Intervention Type: DRUG

One course will last 28 days. Oral administration for 21 consecutive days, with a 1-week washout period. As for the expansion cohort, implemented using the RD estimated in the dose-escalation cohort.

Nivolumab

Intervention Type: DRUG

One course will last 28 days. Given once every 2 weeks at a dose of 3.0 mg/kg.

Level 2

Regorafenib: Oral administration at a dose of 120 mg/day for 21 consecutive days, with a 1-week washout period.

Nivolumab: Given once every 2 weeks at a dose of 3.0 mg/kg.

When it is deemed that there is no problem with safety at the doses described above, tolerability will be verified at the level-3 dosages described below.

Group Type: ACTIVE_COMPARATOR

Regorafenib

Intervention Type: DRUG

One course will last 28 days. Oral administration for 21 consecutive days, with a 1-week washout period. As for the expansion cohort, implemented using the RD estimated in the dose-escalation cohort.

Nivolumab

Intervention Type: DRUG

Definition of DLT:

In principle, a DLT was any of the following Adverse Drug Reactions (ADRs) observed during Cycle 1 (28 days), which was the DLT evaluation period, and was finally determined after discussion in the coordinating committee. According to need, the opinion of the data and safety monitoring committee was to be sought.

• Hematological toxicity Grade 4 neutropenia lasting for more than 7 days. Neutrophil count of <1000/mm3 with a fever of ≥38.0°C. Grade 4 thrombocytopenia or thrombocytopenia with bleeding requiring platelet transfusion. Grade 3 thrombocytopenia with bleeding.
• Non-hematological toxicity. Grade 3 or higher non-hematological toxicity. However, non-hematological toxicities meeting any of the following criteria are classified as DLTs only when the investigator determines it impossible to continue the study even with supportive therapy.

• Grade 3 diarrhea, nausea, vomiting, or anorexia lasting for at least 5 days.
• Grade 3 or higher electrolyte abnormality lasting for at least 7 days.
• Grade 3 or higher skin toxicity lasting for at least 7 days.
• AST or ALT increased ≥5 to 8 times the upper limit of the institutional reference range that does not improve to ≤5 times the upper limit of the institutional reference range within 7 days, with T-Bil increased ≤2 times the upper limit of the institutional reference range.
• AST or ALT increased ≥5 to 8 times the upper limit of the institutional reference range, with T-Bil increased ≥2 times the upper limit of the institutional reference range.
• AST or ALT increased ≥8 times the upper limit of the institutional reference range.
• T-Bil increased ≥3 times the upper limit of the institutional reference range.
• Grade 3 or higher immune-related AEs lasting for at least 8 days even with steroid therapy.
• Overall The case in which 70% of the planned dose of regorafenib was not administered due to toxicities during the DLT evaluation period, or the case in which the specified number of nivolumab doses was not administered.

Patients evaluated for DLT:

At least 3 patients were enrolled at each dose level, and the presence or absence of a DLT was evaluated during the DLT evaluation period.

When there were patients not patient to the assessment for proceeding to the next dose level, additional patients were to be enrolled to allow the DLT evaluation specified in Section "6.1.3 Definition of DLT." Patients enrolled who met any of the following criteria were excluded from the DLT analysis set.

1. Patients in whom regorafenib was not administered for 10 days or longer during Cycle 1 for reasons other than toxicity.

2. Patients in whom no dose of nivolumab was administered during Cycle 1 for reasons other than toxicity.

3. Patients in whom adequate data for DLT evaluation were not obtained due to missing essential testing or other reasons.

Whether to include the following patients in the DLT analysis set was determined by discussion in the coordinating committee: patients who had treatment interruption with regorafenib and nivolumab during Cycle 1 for reasons other than Adverse Events (AEs) or patients who were not allowed to initiate Cycle 2 due to toxicities other than DLT.
