Purpose

The purpose of this study is to evaluate the efficacy and safety of Cabozantinib in Japanese patients with advanced hepatocellular carcinoma (HCC) who have received prior systemic anticancer therapy.

Detailed Description

      The drug being tested in this study is called Cabozantinib. Cabozantinib is being tested to
      treat advanced hepatocellular carcinoma in Japanese patients. This study will look at the
      efficacy and safety of Cabozantinib.

      The study will enroll approximately 32 patients. Participants will be assigned to Cohort A
      (at least 17 participants) or Cohort B (approximately 15 participants) and will receive the
      following treatment. Participants who have received prior sorafenib will enroll to Cohort A
      and participants who have not received prior sorafenib will enroll to Cohort B.

      - Cabozantinib 60 mg

      All participants will be asked to take one tablet of cabozantinib once daily in the fasted
      state (dose at least 2 hours after meal and no more food intake for 1 hour postdose)
      throughout the study.

      This multi-center trial will be conducted in Japan. The overall time to participate in this
      study is approximately at most 3 years. Participants will make multiple visits to the clinic
      during the treatment and posttreatment period, including a follow-up assessment after last
      dose of study drug.

Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:24-Week Progression-Free Survival Rate (PFSR)
Time Frame:Baseline up to 3 years (approximately 2 years after enrollment of the last participant)
Safety Issue:
Description:24-week PFSR is defined as Progression-Free Survival (PFS) proportion at Study Day of Week 25 Day 1 plus 7 days. PFS is defined as time from the first day of study drug administration to the earlier of progressive disease (PD) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) or death due to any cause. PFS will be assessed by independent radiology committee (IRC) per RECIST 1.1 where PD: At least a 20% increase in the baseline sum of the diameters (SoD) of target lesions, taking as a reference the smallest (nadir) SoD since (and including) baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 mm.

Secondary Outcome Measures

Measure:Progression-Free Survival (PFS)
Time Frame:Baseline up to 3 years (approximately 2 years after enrollment of the last participant)
Safety Issue:
Description:PFS is defined as time from the first day of study drug administration to the earlier of PD as assessed by the IRC per RECIST 1.1, or death due to any cause. PD: At least a 20% increase in the SoD of target lesions, taking as a reference the smallest (nadir) SoD since (and including) baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 mm.
Measure:Objective Response Rate (ORR)
Time Frame:Baseline up to 3 years (approximately 2 years after enrollment of the last participant)
Safety Issue:
Description:ORR is defined as the percentage of participants whose best overall response is complete response (CR) or partial response (PR) per RECIST 1.1 by IRC, which is confirmed by a subsequent evaluation conducted >= 28 days later. CR: Disappearance of all target lesions; PR: At least a 30% decrease in SoD of target lesions, taking as a reference the baseline SoD.
Measure:Disease Control Rate (DCR)
Time Frame:Baseline up to 3 years (approximately 2 years after enrollment of the last participant)
Safety Issue:
Description:DCR is defined as the percentage of participants whose best overall response is CR, PR or SD, per RECIST 1.1 by IRC, CR and PR require confirmation by a subsequent evaluation conducted >=28 days later, and SD have to be maintained for at least 8 weeks (51 days) after the first day of study drug administration. CR: Disappearance of all target lesions; PR: At least a 30% decrease in SoD of target lesions, taking as a reference the baseline SoD. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
Measure:Overall Survival (OS)
Time Frame:Baseline up to 3 years (approximately 2 years after enrollment of the last participant)
Safety Issue:
Description:OS is defined as time from the first day of study drug administration to death due to any cause.
