- The study did not achieve its primary end point of median overall survival in the whole population of 78 patients, however, superiority in median overall survival was found in the largest study subpopulation of 56 patients and in secondary end points including objective response in the whole population, strongly supporting the progression into Phase III.
- Dr. Josep Llovet, a Key Opinion Leader in the field of liver cancer, said: “Considering that patients with advanced HCC and severe liver dysfunction do not have any accepted standard of care, the current data from this Phase II trial suggest a signal of efficacy that supports continuing the development of Namodenoson with a Phase III study in this population.”
- Dr. Salomon Stemmer, the Israeli principal investigator, added: “Given the evidence of clinical benefit of Namodenoson, I plan on offering it to selected HCC CPB patients with the drug in the compassionate use setting.”
PETACH TIKVA, Israel I March 26, 2019 I Can-Fite BioPharma Ltd. (NYSE MKT: CANF) (TASE:CFBI), a biotechnology company with a pipeline of proprietary small molecule drugs that address cancer, liver and inflammatory diseases, announced today that the Phase II advanced liver cancer study did not achieve its primary end point of overall survival in the whole population (n=78). At the same time, superiority in overall survival was found in the largest study subpopulation of CPB7 (n=56) and in secondary end points in the whole population, including objective response measured by CT or MRI. These data strongly support the progression into Phase III.
Advanced liver cancer in patients with underlying cirrhosis is categorized into three subclasses based on the severity of cirrhosis, starting with Child Pugh A (CPA), mostly treated with Nexavar® and progressing to Child Pugh B (CPB) and Child Pugh C (CPC), for which there are no drugs on market with proven efficacy.
In the study, the Company enrolled only patients with CPB stage liver cancer with CBP stage patients being further divided into three categories of increasing severity, namely CPB7, CPB8, and CPB9. These patients already failed first line Nexavar and were treated with Namodenoson (25mg), or placebo, as a second line treatment, twice daily, using a 2:1 randomization. The primary endpoint of the study was defined as the length of time the patients lived after receiving treatment or median overall survival (OS). Secondary endpoints included safety, the length of time tumors did not grow after treatment, or progression free survival (PFS), the percent of patients whose tumors partially shrank after treatment, or partial response (PR), and the percent of patients who were PR or stable, or disease control rate (DCR).
Findings from the study include the following:
| |
|
|
|
1. |
|
For the whole population (n=78), median OS was 4.1 months for Namodenoson vs. 4.3 months for placebo (HR: 0.82). |
| |
|
|
|
2. |
|
Pre-planned subpopulation analysis of the CPB7 patients (n=56), revealed that the Namodenoson treated group (n=34) showed median overall survival of 6.8 months vs 4.3 months in placebo (n=22) [HR: 0.77 (95% CI 0.49-1.40)]. Similarly, for this subgroup of patients, PFS was 3.5 months for the Namodenoson treated group vs 1.9 (HR: 0.87) in the placebo group. |
| |
|
|
|
3. |
|
Objective response in the whole patient population measured by CT or MRI, demonstrated that 9% treated by Namodenoson achieved PR vs 0% in the placebo group. |
| |
|
|
|
4. |
|
Consistent with safety results from previously completed clinical trials, Namodenoson was generally well-tolerated, with no treated patients being withdrawn for toxicity and no cases of treatment-related deaths. |
| |
|
|
|
5. |
|
DCR was 18.0% in the Namodenoson group vs 7.1% in the placebo group (p=0.013) after four months of treatment. |
| |
|
|
|
6. |
|
32.0% of patients treated with Namodenoson completed at least 12 months of treatment vs 14.3% who were treated with placebo (p=0.058). |
| |
|
|
|
7. |
|
As of today, two patients in the Namodenoson group are ongoing after 19 and 28 months of treatment, respectively. These patients will continue to receive Namodenoson. |
| |
|
|
|
8. |
|
All nine patients with CBP9 cirrhosis, the most severe grade allowed into the trial, were randomly assigned to the Namodenoson treatment group (OS=3.5 months), a fact which has distorted the results in the whole population. |

Dr. Llovet, a Founder and Director of the Liver Cancer Program and Full Professor of Medicine at the Mount Sinai School of Medicine, New York University, and Professor of Research-ICREA in the BCLC Group, Liver Unit, IDIBAPS-Hospital Clínic, University of Barcelona, stated, “The global incidence of liver cancer continues to increase and has more than tripled in the United States over the last three decades, and currently there are no recommended systemic treatment options for patients with advanced HCC and severe liver dysfunction (Child Pugh B).” Dr. Llovet added, “Considering that patients with advanced HCC and severe liver dysfunction do not have any accepted standard of care, the current data from this Phase II trial suggest a signal of efficacy that supports continuing the development of Namodenoson with a Phase III study in this population. I will be happy to help with the design of the Phase III and serve as the principal investigator of the trial.”
Dr. Salomon M Stemmer, Institute of Oncology, Davidoff Center, Rabin Medical Center, Petah Tikva/Sackler Faculty of Medicine, Tel Aviv University, Israel and the study principal investigator, added, “Given the evidence of Namodenoson’s clinical benefit, I plan on offering it to selected HCC CPB patients in the compassionate use setting.”
“We are encouraged by the advantage shown by Namodenoson in the CPB7 HCC population, a group for which there are no drugs with proven effectiveness,” stated Pnina Fishman, Chief Executive Officer of Can-Fite. “Since Namodenoson has a favorable safety profile and shows no evidence of hepatotoxicity, it may possess a unique therapeutic index in this high-need population. Given that Namodenoson has been granted Fast Track status by the FDA, we look forward to engaging regulatory authorities in a dialog at the earliest opportunity.”
An abstract for the late-breaking session has been submitted to The American Society of Clinical Oncology (ASCO) annual meeting, to take place May, 2019 in Chicago, IL, USA.

About Namodenoson
Namodenoson is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). Namodenoson is being evaluated in Phase II trials for two indications, as a second line treatment for hepatocellular carcinoma, and as a treatment for non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). A3AR is highly expressed in diseased cells whereas low expression is found in normal cells. This differential effect accounts for the excellent safety profile of the drug.
