Future developments
AASLD-JNCI guidelines in HCC
Trial design
Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71.
HCC trial design strategy recommended by
AASLD expert panel
Early clinical
research phase
Phase 1/2 study
Randomized phase 2
Advanced clinical
research phase
Combined phase 2–3
Phase 3
study

Combined phase 1/2 studies in cirrhotic patients will capture liver-specific
toxic effects of new drugs

Randomized phase 2 trials are pivotal in HCC research because they enable
reliable comparison with standard of care

Phase 3 studies remain the main source of evidence in HCC research

Phase 2/3 studies may be appropriate in very specific circumstances, where
the drug proposed would require fast-track assessment
Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71.
Endpoints in clinical trials recommended by
AASLD expert panel
Recommended primary and secondary endpoints
Survival
Time from randomization to death. Patients alive at the end of follow-up are censored
•Primary endpoint in phase 3 studies assessing primary treatments
•Primary/secondary endpoint in phase 2/3 studies assessing adjuvant or neoadjuvant
treatments
•Secondary endpoint in phase 2 studies assessing primary treatments
Time to recurrence
(TTR)*
Time from randomization to recurrence. Evidence of recurrence should follow the
RECIST amendments. Once evidence of HCC recurrence is confirmed, TTR will be
defined as the time that recurrence was first suspected
•Primary/secondary endpoint in phase 2/3 studies assessing adjuvant or neoadjuvant
treatments
Time to progression*
Time from randomization to radiological progression. Definition of progression is
based on the RECIST amendments. Deaths during follow-up without evidence of
radiological progression are censored
•Primary endpoint in phase 2 studies assessing primary treatments
•Secondary endpoint in phase 3 studies assessing primary treatments
Time to local
recurrence*
Time from randomization to local radiological progression. Definition of progression is
based on the RECIST amendments. Deaths during follow-up without evidence of
radiological progression are censored
•Secondary endpoint in studies assessing locoregional therapies
*Time to progression and time to local recurrence can vary considerably if evaluation interval varies among studies or between
study arms of an individual study.
RECIST = Response Evaluation Criteria in Solid Tumors.
Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71.
Endpoints in clinical trials recommended by
AASLD expert panel
Recommended primary and secondary endpoints
Tertiary endpoints†
Cancer-specific
death
Time from randomization to HCC-related death. Patients alive at the end of followup are censored
•Competing risk analysis is recommended to assess this endpoint
Time to symptomatic
progression
Time from randomization to deterioration of symptoms as assessed by a
standardized questionnaire
•No reliable questionnaires have been thoroughly validated in HCC research
Disease-free survival
Composite endpoint. Time from randomization to either recurrence or death.
Patients alive and free of recurrence at the end of follow-up are censored
•Vulnerable endpoint in HCC research
Progression-free
survival
Composite endpoint. Time from randomization to either radiological progression or
death. Patients alive and free of progression at the end of follow-up are censored
•Vulnerable endpoint in HCC research
Response rate
Definition of response is based on the RECIST amendments
† Tertiary
endpoints include composite endpoints that are vulnerable in HCC research, such as disease-free and
progression-free survival, that are difficult to measure with standard tools, such as time to symptomatic progression, or that
are not time-to-event endpoints, such as response rate or disease control rate.
RECIST = Response Evaluation Criteria in Solid Tumors.
Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71.
Other recommendations of AASLD expert
panel on HCC trial design
 Target population
• selection of the target population should be based on the
Barcelona Clinic Liver Cancer staging system
• new drugs should be tested in patients with well preserved liver
function (Child–Pugh A class)
 Control arm in clinical trials
• patients assigned to the control arm should receive standard-ofcare therapy, namely TACE for patients with intermediate-stage
disease and sorafenib for patients with advanced-stage disease

Outcome prediction in HCC
Model of HCC prognosis combining clinical and genomic data
In patients with early stage tumors, survival is mostly determined by genomic data coded
in non-tumoral cirrhotic tissue (‘field effect’), because it determines the risk of liver
dysfunction and development of a de novo HCC

As cancer progresses, genomic data from the tumor increases its prediction capacity
because cancer-related death limits survival in patients with advanced disease
