Clinical Trial Summary

The CaPture trial is a prospective, multi-centre, non-randomized phase II study. Its aim is to assess feasibility, safety and efficacy signals of Cabozantinib treatment in patients with HCC and prior non-response or disease progression during a PD-1 or PD-L1 inhibitor treatment. Since the potential study population is very small, the sample size has been fixed in advance to N = 40. Time on treatment (TT) will be measured as primary endpoint.

Description:

Patients will be recruited at the participating trial sites (up to ten trial sites), which are all specialized in treatment of patients with HCC. Once potential patients are identified by trial physicians, they will be asked for trial participation and informed consent by one investigator of the CaPture trial. Patients included within 4 weeks after diagnosis of failure of preceding PD-1/PD-L1 inhibitory treatment.

After baseline, visits are previewed on a 4weekly (28 days) basis during the whole duration of Cabozantinib study treatment, which can be used for a maximum of 12 months (336 days). The treatment with Cabozantinib will be performed in accordance with the valid license and according to the judgement of the treating physician.The tablet is taken once a day, starting normally with the highest dosage (60 mg). The doses 20mg and 40mg are still available and can be used for dose reduction. During the visits, the patient will be questioned for compliance and side effects and examined for clinical and laboratory parameters.

Response to Cabozantinib should be assessed at least every 12 weeks (84 days) by either CT scan or MRI.

After termination of Cabozantinib study treatment the first follow-up visit takes place one month after the end of therapy in person. Further follow-up visits can be done by phone to collect patient's status and further treatment.

In addition to the time on treatment (TT), survival, response, feasibility, biomarkers, health status and safety should also be tested.

Furthermore there is an concomitant scientific project. The aim of this project is to examinate the association of HCC related biomarkers with response to Cabozantinib in patients treated in the CaPture study. For this, we will analyse liver biopsy samples as well as circulating markers in patients who are willing to participate in the project.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	time on treatment (TT)	Primary endpoint of the trial is the time on treatment (TT). TT is defined as one plus the last date of treatment with Cabozantinib minus the first date of treatment with Cabozantinib, and will be measured in days (note that Cabozantinib will be administered as a single dose per day). The end of treatment must be confirmed by the investigator. In particular, planned discontinuations or missing compliance will not be considered as end of treatment without confirmation.	start of treatment until end of treatment (max. 336 days)
Secondary	Overall survival (OS)	Overall survival (OS), is the time to death of any cause. OS is measured in days, defined as death date minus registration date.	screening visit until date of death, maximum until the last registered patient reached the second follow-up (6 months after end of therapy)
Secondary	Progression-free survival (PFS)	Progression-free survival (PFS) is the time to tumor progression or death of any cause, whichever comes first. PFS is measured in days, defined as date of diagnosis of tumor progression by mRECIST criteria minus registration date. If a patient dies without previous diagnosis of tumor progression, date of diagnosis is replaced by death date.	screening visit until the time to tumor progression or date of death from any cause, whichever came first, maximum until the last registered patient reached the second follow-up (6 months after end of therapy)
Secondary	Duration of response (DoR)	is the time from achievement of response (i.e., measurement criteria for CR or PR are first met, cf. Eisenhauer et al., 2009, p. 236) until the first date that tumor recurrence or progression is documented (taking as reference the smallest measurements recorded in the study) or death of any cause, whichever comes first. DoR is measured in days, defined as date of documentation of tumor progression by mRECIST criteria minus date of documentation of tumor response (CR or PR). If a patient dies without previous diagnosis of tumor progression, date of progression documentation is to be replaced by death date. If CR or PR will never be documented for a patient, DoR is set to "zero".	screening visit until the time from achievement of response or date of death from any cause, whichever came first, maximum until the last registered patient reached the second follow-up (6 months after end of therapy)
Secondary	Response rates	Response rates, measured in percent, are defined as the number of patients whose best tumor response observed by mRECIST criteria is CR, PR, SD or PD, respectively, divided by the total number of registered patients. The overall response rate (ORR) is defined as the number of patients whose best tumor response observed by mRECIST criteria is CR or PR divided by the total number of registered patients.	screening visit until end of treatment (max. 336 days)
Secondary	Median average dose	Median average dose, measured in milligram (mg). Averages of all Cabozantinib doses administered will be calculated weekly from first date of treatment until end of treatment. Discontinuations of treatment for any reason, including missing compliance, will be included into this calculation as zero doses. Median average dose is defined as the median of the obtained sequence of averages.	start of treatment until end of treatment (max. 336 days)
Secondary	Image-based endpoint: Tumor progression	Tumor progression, assessed at Visits 3, 6, 9, 12 and EoT visit (if applicable) in comparison to the state at Screening, by mRECIST criteria.	screening until end of treatment (max. 336 days)
Secondary	Image-based endpoint: Progression of tumoral macrovascular invasion	Progression of tumoral macrovascular invasion of hepatic and/or portal vein branches, assessed at Visits 3, 6, 9, 12 and EoT visit (if applicable) according to the working instruction for radiologists, in comparison to state at Screening.	screening until end of treatment (max. 336 days)
Secondary	Image-based endpoint: Progression of extrahepatic HCC manifestations	Progression of extrahepatic HCC manifestations, assessed at Visits 3, 6, 9, 12 and EoT visit (if applicable) according to the working instruction for radiologists, in comparison to state at Screening.	screening until end of treatment (max. 336 days)
Secondary	Image-based endpoint: Total tumor volume	Total tumor volume (TTV), assessed at Screening, Visits 3, 6, 9, 12 and EoT visit (if applicable), measured in cm^3 according to the working instruction for radiologists.	screening until end of treatment (max. 336 days)
Secondary	Image-based endpoint: Affection rate	Affection rate, assessed at Screening, Visits 3, 6, 9, 12 and EoT visit (if applicable), measured in percent. Affection rate is defined as total tumor volume divided by total liver volume, both measured in cm^3 according to the working instruction for radiologists.	screening until end of treatment (max. 336 days)
Secondary	Concentration of Alpha-fetoprotein (AFP),	Concentration of Alpha-fetoprotein (AFP), measured in µg/l, at Screening and Visits 0, 3, 6, 9, 12 and EoT visit (if applicable).	screening until end of treatment (max. 336 days)
Secondary	Child-Pugh classification score	Child-Pugh classification score, measured in levels from A to C, at Screening and Visits 3, 6, 9, 12, EoT and FU1 (if applicable).	screening until first follow-up (one month after EoT)
Secondary	ECOG Performance Status	ECOG Performance Status, measured in levels from 0 to 5, at Screening and Visits 3, 6, 9, 12, EoT and FU1 (if applicable).	screening until first follow-up (one month after EoT)
