A Phase 2 Study of Cabozantinib in Japanese Participants With Advanced Hepatocellular Carcinoma

A Phase 2, Open-Label, Single-Arm Study of Cabozantinib in Japanese Patients With Advanced Hepatocellular Carcinoma Who Have Received Prior Systemic Anticancer Therapy

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

Study Overview

• Status: Completed
• Conditions: Advanced Hepatocellular Carcinoma
• Intervention / Treatment: Drug: Cabozantinib

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 34 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
24-Week Progression-Free Survival Rate (PFSR)	24-week PFSR=percentage of participants with progression-free survival (PFS) of at least 24 weeks at Week 25 Day 1 plus 7 days. PFS=time from first day of study drug administration to earlier of progressive disease (PD) or death due to any cause per Response Evaluation Criteria in Solid Tumors Version 1.1(RECIST 1.1). PD=at least a 20% increase in sum of target lesion diameters (SoD) with reference to smallest(nadir) SoD. In addition to relative increase of 20%, SoD must also demonstrate an absolute increase of at least 5 mm. For nontarget lesion time Point Response, unequivocal progression of nontarget lesions. Modest 'increase' in size of one or more nontarget lesions is usually not sufficient to quality for unequivocal progression status, it must not be representative of single lesion increase. Lesion in an anatomical location and not scanned at baseline is considered new lesion. Lesion qualifies as PD if finding is unequivocally not due to change in imaging technique or modality.	Week 25 Day 1 plus 7 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS)	PFS was defined as time from the first day of study drug administration to the earlier of PD per RECIST 1.1 as assessed by IRC or death due to any cause. Per RECIST 1.1, for target lesion time point response, PD was defined 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. For nontarget lesion time point response, unequivocal progression of nontarget lesions. A modest 'increase' in the size of one or more nontarget lesions is usually not sufficient to quality for unequivocal progression status. It must be representative of overall disease status change, not a single lesion increase. The lesion qualifies as a PD if the finding is unequivocally not due to a change in the imaging technique or modality.	Until disease progression, or death or end of study (Up to approximately 2.8 years)
Objective Response Rate (ORR)	ORR was defined as the percentage of participants whose best overall response was complete response (CR) or partial response (PR) per RECIST 1.1 as assessed by IRC, which was confirmed by a subsequent evaluation conducted >= 28 days later. Per RECIST 1.1, for target lesion time point response, CR was defined disappearance of all target lesions. All pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm. For nontarget lesion time point response, disappearance of all nontarget lesions. All lymph nodes must be nonpathological in size (<10 mm short axis); PR was defined as at least a 30% decrease in SoD of target lesions, taking as a reference the baseline SoD.	Up to approximately 2 years
Disease Control Rate (DCR)	DCR=percentage of participants whose best overall response is CR,PR or SD, per RECIST 1.1, CR and PR require confirmation by subsequent evaluation conducted >=28 days later, and SD have to be maintained for at least 8 weeks after first day of study drug administration. CR=disappearance of all target lesions. All pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm. For nontarget lesion time point response, disappearance of all nontarget lesions. All lymph nodes must be nonpathological in size (<10 mm short axis); PR=at least a 30% decrease in SoD of target lesions, taking as reference baseline SoD; SD=neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD; SoD must also demonstrate an absolute increase of at least 5 mm; PD=at least a 20% increase in SoD of target lesions, taking as a reference smallest (nadir) SoD.	Up to approximately 2 years
Overall Survival (OS)	OS was defined as time from the first day of study drug administration to death due to any cause. Participants without documentation of death were censored on the date they were last known to be alive.	Up to end of study (Up to approximately 2.8 years)
