Clinical Trial Summary

This is a multicenter, randomized, double-blind, placebo-controlled clinical trial in subjects with advanced HCC and CPB cirrhosis whose disease has progressed while taking 1 prior systemic drug therapy for HCC.

Description:

The trial will evaluate the efficacy and safety of CF102 as compared to placebo. Subjects will be randomly assigned in a 2:1 ratio to treatment with oral doses of either CF102 25 mg or matching placebo administered twice daily (BID) for consecutive, 28-day cycles. Subjects will be evaluated regularly for safety. Tumor imaging will be performed every 8 weeks. Treatment will continue until the subject experiences unacceptable drug-related intolerability. Subjects will return for a follow-up visit 28 days after completion of the last dose of study drug, and every attempt will be made to obtain survival data on all randomized subjects. Subjects who discontinue will be followed indefinitely for survival status. The trial will continue until 75 deaths have been recorded.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects With Overall Survival	Evaluate the efficacy of orally administered CF102 25 mg twice daily (BID) as compared to placebo, as determined by Overall Survival (OS), when used as second-line therapy in subjects with advanced hepatocellular carcinoma (HCC) and Child-Pugh Class B (CPB) cirrhosis. Overall Survival is defined as the time from Baseline (Cycle 1 Day 1) to death due to any cause, calculated as (date of death- date of Cycle 1 Day 1) +1.OS will be summarized in months, which will be obtained by dividing OS in days by 30 days/month. Summary statistics will be determined using the Kaplan-Meier (KM) estimate of the survival function and the between-treatment comparison will be performed using the logrank test as the primary analysis.	From date of first treatment (Cycle 1 Day 1) until date of death from any cause, assessed up to 12 months
Secondary	Time to Progression (TTP)	Time to Progression (TTP) is the time from Baseline to the first Overall Response of Progressive Disease (PD), calculated as date of first PD - date of Cycle 1 Day 1+1. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. TTP will be summarized in months, which will be obtained by dividing TTP in days by 30 days/month. Summary statistics will be determined using the KM estimate of the survival function for TTP. The between-treatment comparison will be performed using the logrank test.	From date of first treatment (Cycle 1 Day 1) until the date of first documented progression, assessed up to 36 months
Secondary	Time to Progression-Free Survival (PFS)	Time to Progression-Free Survival (PFS) is the time from Baseline to the first Overall Response of Progressive Disease (PD) or death due to any cause if the subject dies without experiencing PD, calculated as date of first PD or date of death - date of Cycle 1 Day 1+1. PFS will be summarized in months, which will be obtained by dividing PFS in days by 30 days/month. Summary statistics will be determined using the KM estimate of the survival function for PFS. The between-treatment comparison will be performed using the logrank test.	From date of first treatment (Cycle 1 Day 1) until the date of first documented disease progression or date of death, which occurred first, assessed up to 36 months
Secondary	Objective Response Rate (ORR)	Objective Response Rate (ORR) is assessed as the percentage of subjects who achieved a Complete Response (CR) or Partial Response (PR). Per RECIST criteria v1.1, CR is defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10mm; PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Overall Response is the sum of subjects achieving CR or PR.	The end of even-numbered cycles (Cycle 3 Day 1,Cycle 5 Day 1,Cycle 7 Day 1, Cycle 9 Day 1, Cycle 11 Day 1) assessed up to 12 months
Secondary	Disease Control Rate (DCR)	Disease Control Rate (DCR) is assessed as the percentage of subjects who achieved a Complete Response (CR), Partial Response (PR) or Stable Disease (SD) using RECIST criteria. Per RECIST criteria v1.1, CR is defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10mm; PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for Progressive Disease (at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm) taking as reference the smallest sum diameters while on study.	The end of even-numbered cycles (Cycle 3 Day 1,Cycle 5 Day 1,Cycle 7 Day 1, Cycle 9 Day 1, Cycle 11 Day 1) assessed up to 12 months
Secondary	Summary Statistics of Laboratory Parameters Associated With Viral Hepatitis, Hepatic Dysfunction, and Cirrhosis	The raw and change from baseline (CFB) for each laboratory parameter (alanine aminotransferase (ALT), albumin, aspartate aminotransferase (AST), bilirubin (direct and total), International Normalized Ratio (INR),and prothrombin time (PT)) will be summarized by treatment and visit. CFB is calculated as (Value at Post-Baseline visit - Value at Baseline). The baseline value used in the calculations of CFB is the value taken at Cycle 1 Day 1.	Baseline (Cycle 1 Day 1); Cycle 11 Day 15
Secondary	Summary Statistics of White Blood Cell (WBC) Adenosine A3 Receptor (A3AR) Expression and Clinical Response - WBC Adenosine A3 Receptor (A3AR) Expression	Summary statistics for WBC adenosine A3 receptor (A3AR) expression and CFB in WBC A3AR expression will be provided by treatment and visit. A3AR mRNA expression in WBC was determined from blood collected to a PAXgene RNA tubes (Qiagen, Venlo, The Netherlands), using the QuantiGene Plex 2.0® assay (Thermo Fisher, Waltham, MA, USA). ß-actin was used as a reference control, and the oligonucleotide probe sets were designed by Thermo Fisher. Luminescence from each specific probe set was captured by Glomax Multi (Promega, Madison, WI, USA). A3AR was expressed in units, where 1 unit was defined as the mean of A3AR expression in healthy subjects (n = 50). Healthy subjects were 20-70 years of age with no known illness and no prior treatment.	Baseline (Cycle 1 Day 1) and Cycle 11 Day 1
