Can-Fite’s completed Phase II liver cancer study found that Namodenoson increased overall survival in HCC patients with Child Pugh B7 (CPB7), the largest subpopulation of the study, as compared to placebo, even though the trial did not meet its primary endpoint. The Company recently completed a successful End-of-Phase II meeting with the U.S. Food and Drug Administration (FDA), in which the FDA agreed with Can-Fite’s proposed pivotal Phase III trial design to support a New Drug Application (NDA) submission and approval of Namodenoson in the treatment of HCC.

"The ISCORT is the most prestigious Israel oncology forum to discuss novel treatments in different malignancies and enable the creation of collaboration between leading investigators in the field. We are confident that Dr. Stemmer’s presentation will open the door for the participation of leading oncologists in the Company’s Phase III study", said Dr. Fishman, Can Fite CEO.

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 as a second line treatment for hepatocellular carcinoma, with a recently completed Phase II trial and planned Phase III trial in this indication. The drug is currently in an ongoing Phase II trial 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.

HMBD-001 is a unique anti-HER3 antibody with a novel mechanism of action and favorable safety profile. HER3 is a member of the EGFR tyrosine kinase receptor family, which is responsible for driving cancer cell division and growth, and is expressed in over half of colorectal and gastric cancers, at least a third of breast cancers, as well as significant sub-populations of many other indications.[1] HER3 activation is implicated in cancer progression as well as in acquired resistance to drugs against other tyrosine kinase receptor family members such as EGFR (e.g. cetuximab or Erbitux) and HER2 (e.g. trastuzumab or Herceptin). HMBD-001 was developed using Hummingbird Bioscience’s proprietary Rational Antibody Discovery Platform to specifically bind to and inhibit a difficult-to-access region of the HER3 protein that is essential for activation.

The published findings show that HMBD-001 (also known as 10D1F) is superior at tumor growth inhibition, regardless of how HER3 is activated, compared to previous anti-HER3 drugs with different binding sites and mechanisms of action. HMBD-001 demonstrated potent efficacy in a broad panel of in vitro and in vivo tumor models that had high HER3 activity and oncogenic downstream signaling.

"Previous attempts to target HER3 with other drugs failed as they could not inhibit activation of HER3 effectively. The highly specific binding of HMBD-001 to a difficult-to-target region on HER3 allows us to completely shut off activation of this important cancer-associated protein," said Dr Jerome Boyd-Kirkup, Chief Scientific Officer and co-founder, Hummingbird Bioscience. "This preclinical data provides proof-of-concept and represents exciting therapeutic opportunities for us as we look to develop HMBD-001 in hard-to-treat conditions such as gastric, colorectal, lung and pancreatic cancers."

Hummingbird Bioscience, in partnership with Cancer Research UK, will be advancing HMBD-001 into clinical trials for the treatment of HER3 driven cancers. Manufacturing of the material for the Phase 1 clinical trial of HMBD-001 is underway and is expected to be completed in the second half of 2020.

About HMBD-001

HMBD-001 represents a unique, highly-specific, anti-HER3 neutralizing antibody with a novel mechanism of action that offers significant potential for broad clinical benefit. Previous attempts to block the HER3 receptor, a key player in the signaling pathway that promotes cell division and tumor growth in cancer, have not proven to be efficacious. HER3 is activated by the binding of neuregulin (NRG1), which stabilizes a transient open conformation to allow it to form heterodimers with HER2/EGFR. In the presence of abundant HER2/EGFR, heterodimers can form without NRG1.

Preclinical models have shown that HMBD-001 is able to effectively and uniquely bind to a
difficult-to-target region on HER3, blocking the heterodimerization of HER3 with HER2/EGFR independent of NRG1 binding. This potently inhibits the activation of the signaling pathway – and consequently, stops tumor growth.

Cancer Research UK has partnered with Hummingbird Bioscience to advance this novel antibody drug into clinical trials for the treatment of HER3 driven cancers. The clinical trial of this investigational candidate is expected to commence following the completion of manufacturing and the subsequent submission of regulatory approval.

On January 7, 2020 The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) reported how resistance to a promising targeted drug develops in patients with a rare, lethal cancer of the bile ducts called cholangiocarcinoma (Press release, The Ohio State University Comprehensive Cancer Center, JAN 7, 2020, View Source [SID1234553217]).

The study, reported in the journal Molecular Cancer Therapeutics, also suggests that adding another drug at the time of progression might re-sensitize tumor cells to the initial drug, called an FGFR inhibitor.

"While the majority of patients with FGFR-positive cholangiocarcinoma benefit from new FGFR inhibitors in clinical trials, most patients unfortunately develop cancers resistant to the drugs," says study leader Sameek Roychowdhury, MD, PhD, a medical oncologist and researcher at the OSUCCC – James. "We believe that this study is an important step in understanding drug resistance and improving the treatment of this and other cancers caused by abnormal FGFR gene mutations."

Findings also suggest that monitoring fragments of circulating tumor DNA for acquired mutations that cause resistance to FGFR inhibitors may reveal the presence of resistance mutations and mark the time a patient should begin taking the additional drug, an mTOR inhibitor.

The successful treatment of cholangiocarcinoma is challenging because the disease is usually diagnosed at an advanced stage that has a five-year survival rate of 2%. Patients diagnosed earlier also have low, five-year survival due to high rates of disease recurrence. Abnormal activation of the FGFR gene happens in 15 to 20% of people with cholangiocarcinoma, and FGFR inhibitors show effectiveness in 70 to 80% of those patients until resistance develops. There are six studies of FGFR inhibitors in clinical trials at the OSUCCC – James.

"A better understanding of how treatment resistance develops and how to prevent it is critical for improving the treatment of cholangiocarcinoma and other cancers caused by FGFR mutations," says first author Melanie Krook, PhD, a postdoctoral fellow in Roychowdhury’s lab.

"Our findings suggest that cholangiocarcinoma patients treated with an FGFR targeted therapy could potentially benefit from combination therapies with other drugs such as mTOR inhibitors. Additional laboratory studies are needed to identify the optimal lead strategies for this combination," she adds.

For this study, Roychowdhury, Krook and colleagues examined the FGFR (fibroblast growth factor receptor) gene in the cancer cells of a cholangiocarcinoma patient who died after experiencing disease progression and developing resistance to the FGFR inhibitor infigratinib.

The researchers identified two acquired FGFR mutations in the patient’s tumor cells that conferred resistance to FGFR inhibitors. They then used cancer cell lines to learn that the mutations led to activation of the mTOR biochemical pathway. This enabled the cancer cells to grow even in the presence of FGFR inhibitors. Adding an mTOR inhibitor to the cells restored their sensitivity to FGFR inhibitors.

Key findings:

Two acquired FGFR2 mutations, p.E565A and p.L617M, were shown to drive resistance to the FGFR inhibitor infigratinib.

The p.E565A mutation upregulates the mTOR signaling pathway, which desensitizes cholangiocarcinoma cell lines to infigratinib and other FGFR inhibitors.

A drug that inhibited the mTOR pathway restored the sensitivity of the cells to infigratinib and other FGFR inhibitors.

"Overall, our findings suggest that an mTOR inhibitor administered at the time of progression may re-sensitize tumor cells to an FGFR inhibitor in patients who develop resistance to these agents," Roychowdhury says.

This study was supported by grants from the American Cancer Society (MRSG-12-194-01-TBG), the Prostate Cancer Foundation, the National Institutes of Health (HG006508, CA202971, CA216432), the American Lung Association and Pelotonia.
