About TORL-1-23

TORL-1-23 is an anti-CLDN6 humanized monoclonal antibody coupled to MMAE via a cleavable linker. CLDN6 is overexpressed in multiple cancers with limited to no detectable expression in normal tissues, thus an ideal target for an ADC. TORL 1-23 is highly selective; in vitro TORL-1-23 exhibited robust and selective binding to CLDN6-overexpressing cell lines without binding to cell lines over-expressing other claudins, such as CLDN3, CLDN4, and CLDN9. TORL-1-23 is in clinical trials for treatment of CLDN6+ cancers including ovarian cancer and NSCLC.

About TORL123-001 (TRIO-049) Clinical Study

TORL BioTherapeutics is currently enrolling patients in a phase I study, TORL123-001 (TRIO-049), to assess the safety, pharmacokinetics, biomarkers, and antitumor activity of TORL-1-23. Further details including current study sites can be found at View Source

Under the agreement, Innovent will conduct a Phase 1b study to evaluate the anti-tumor activity and safety of the combination therapy of IBI351(GFH925) with cetuximab in Chinese patients with advanced or metastatic NSCLC harboring KRASG12C mutation. Merck KGaA, Darmstadt, Germany will provide clinical drug supplies of cetuximab in this multi-center trial in China. Cetuximab as a monotherapy or as a combination therapy has not been approved in any country for patients with advanced NSCLC.

Currently, Innovent is conducting a single-arm registrational trial of IBI351(GFH925) monotherapy in previously-treated advanced non-small cell lung cancer patients with KRASG12C mutation in China, with expected NDA filing by the end of 2023. A Phase 1b study of IBI351(GFH925) in combination with sintilimab for previously untreated advanced NSCLC patients with KRASG12C mutation is also under exploration. Latest data of a Phase 1 study of IBI351(GFH925) monotherapy in 67 previously-treated NSCLC patients with KRASG12C mutation were presented at the 2023 American Association for Cancer Research (AACR) (Free AACR Whitepaper)(AACR) Annual Meeting [Link].

Dr. Hui Zhou, Senior Vice President of Innovent, stated: "We are pleased to collaborate with Merck KGaA, Darmstadt, Germany to further explore the potential of IBI351 and cetuximab combination therapy in the early line setting for NSCLC patients harboring KRASG12C mutation, and shed light on next-step clinical development. The combination of a KRASG12C inhibitor and an EGFR inhibitor has shown efficacy in heavily pre-treated patients with metastatic colorectal cancer [1],[2],[3]. Preclinical studies of IBI351 and cetuximab combination therapy also demonstrated potential anti-tumour activity in NSCLC. Innovent has observed favorable safety and promising antitumor activity of IBI351 monotherapy in previously-treated advanced NSCLC harboring KRASG12C mutation, and we are actively expanding treatment lines, hoping to provide better treatment options for more cancer patients. "

About IBI351/GFH925 (KRASG12C Inhibitor)

RAS protein family can be divided into KRAS, HRAS and NRAS categories. KRAS mutation are detected in nearly 90% of pancreatic cancer, 30-40% of colon cancer, and 15-20% lung cancer patients. The occurrence of KRAS G12C mutation subset is more frequently observed than those with ALK, ROS1, RET and TRK 1/2/3 mutations combined.

Discovered by GenFleet Therapeutics, GFH925 (Innovent R&D code: IBI351) is a novel, orally active, potent KRASG12C inhibitor designed to effectively target the GTP/GDP exchange, an essential step in pathway activation, by modifying the cysteine residue of KRASG12C protein covalently and irreversibly. Preclinical cysteine selectivity studies demonstrated high selectivity of IBI351 towards G12C. Subsequently, IBI351 effectively inhibits the downstream signal pathway to induce tumor cells’ apoptosis and cell cycle arrest.

In September 2021, Innovent and GenFleet Therapeutics entered into an exclusive license agreement for the development and commercialization of IBI351 in China (including mainland China, Hong Kong, Macau and Taiwan) with additional option-in rights for global development and commercialization.

In January 2023, the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) has granted Breakthrough Therapy Designation (BTD) for IBI351 for the treatment of patients with advanced non-small cell lung cancer (NSCLC) harboring KRASG12C mutation who have received at least one systemic therapy. In May 2023, the CDE of China’s NMPA granted another BTD for IBI351 for the treatment of previously treated advanced colorectal carcinoma (CRC) patients with KRASG12C mutation.

About Cetuximab (ERBITUX)

Cetixumab (ERBITUX) is an IgG1 monoclonal antibody targeting the epidermal growth factor receptor (EGFR). As a monoclonal antibody, the mode of action of cetuximab is distinct from standard non-selective chemotherapy treatments in that it specifically targets and binds to the EGFR. This binding inhibits the activation of the receptor and the subsequent signal-transduction pathway, which results in reducing both the invasion of normal tissues by tumor cells and the spread of tumors to new sites. It is also believed to inhibit the ability of tumor cells to repair the damage caused by chemotherapy and radiotherapy and to inhibit the formation of new blood vessels inside tumors, which appears to lead to an overall suppression of tumor growth. Based on in vitro evidence, cetuximab also targets cytotoxic immune effector cells towards EGFR-expressing tumor cells (antibody-dependent cell-mediated cytotoxicity [ADCC]).

ERBITUX has already obtained market authorization in over 100 countries worldwide for the treatment of RAS wild-type metastatic colorectal cancer and for the treatment of squamous cell carcinoma of the head and neck. Merck licensed the right to market ERBITUX, a registered trademark of ImClone LLC, outside the U.S. and Canada from ImClone LLC, a wholly owned subsidiary of Eli Lilly and Company, in 1998.

Clinical and Corporate Development Highlights Include:

NAMODENOSON

Oncology

Pivotal Phase 3 Liver Cancer Study—Can-Fite’s ongoing pivotal Phase 3 liver cancer study is designed to assess Namodenoson in the treatment of patients with advanced hepatocellular carcinoma (HCC) and underlying Child Pugh B7 (CPB7) who have not responded to 1 or 2 other lines of therapy. The primary endpoint is overall survival. An interim analysis will be performed.

During the first quarter, a study titled "Targeting the A3 adenosine receptor to treat hepatocellular carcinoma: anti-cancer and hepatoprotective effects" was published in the peer-reviewed journal Purinergic Signalling.

Phase 2a Pancreatic Cancer Study—Can-Fite is preparing for an open-label Phase 2 exploratory trial to assess the safety and efficacy of Namodenoson in the treatment of patients with pancreatic cancer who have received at least one previous systemic therapy. Safety and efficacy endpoints including objective response, progression-free survival, duration of response, disease control, and overall survival will be monitored. The study will be conducted by Dr. Salomon Stemmer, an oncology key opinion leader and Professor at the Institute of Oncology, Rabin Medical Center, Israel. In pre-clinical studies, Namodenoson had a significant anti-cancer effect in pancreatic carcinoma as a monotherapy and an additive effect when combined with gemcitabine, the standard-of-care chemotherapy for pancreatic cancer. The mechanism of action entails de-regulation of the Wnt signal transduction pathway, a key modulator of pancreatic carcinoma cell growth.

Can-Fite filed a patent application that covers the use of Namodenoson for the treatment of pancreatic cancer. Moreover, Can-Fite’s pancreatic cancer program received recognition from ASCO (Free ASCO Whitepaper) when its study titled "Effects of Namodenoson on Pancreatic Carcinoma: Preclinical Evidence" was published in the Journal of Clinical Oncology supplement of the 2023 ASCO (Free ASCO Whitepaper) Annual Meeting Proceedings.

Pancreatic cancer is an unmet medical need. According to the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper), in 2020, an estimated 496,000 people were diagnosed with pancreatic cancer globally and an estimated 466,000 died from the disease. The 5-year survival rate for people with pancreatic cancer in the U.S. is 11%. Acumen Research estimates the global pancreatic cancer therapeutics market was valued at approximately $3.6 billion in 2021 and is projected to grow to approximately $6.6 billion by 2030.

Liver Diseases

Phase 2b NASH Study—A Phase 2b NASH study is currently ongoing to evaluate Namodenoson’s efficacy as compared to placebo, determined by a histological endpoint. Namodenoson met its primary endpoint of reducing liver fat, inhibiting fibrosis, and demonstrating an anti-inflammatory effect in a prior Phase 2a NASH study.

Compassionate Use in Patients with Decompensated Liver Cirrhosis—Based on data showing that Namodenoson has liver protective effects, Namodenoson is now given to patients with decompensated cirrhosis, an advanced form of cirrhosis associated with liver failure for which there are no therapeutic options other than liver transplantation. Patients will be treated with Namodenoson at the Soroka Medical Center in Israel under compassionate use.

Decompensated cirrhosis is an acute deterioration in liver function in patients with cirrhosis, characterized by jaundice, ascites, hepatic encephalopathy, hepatorenal syndrome, or variceal hemorrhage. This is an unmet medical need and there is no therapeutic approach that has shown efficacy in slowing disease progression. An estimated 10.6 million people globally had decompensated cirrhosis in 2017, with few treatment options available aside from liver transplants if the decompensated cirrhosis has reached an advanced stage. The treatment of liver cirrhosis in the U.S. is estimated to become an approximately $15 billion market by 2030.

PICLIDENOSON

Green Light from EMA for a Pivotal Phase 3 Psoriasis Study—The European Medicines Agency (EMA) gave Can-Fite a positive opinion on its registration plan for a pivotal Phase 3 clinical trial for Piclidenoson in the treatment of moderate to severe psoriasis. The pivotal study and the safety of the 3 mg twice daily dose of Piclidenoson are accepted by the agency.

Can-Fite has submitted a comparable data package to the U.S. Food and Drug Administration (FDA) and expects a similar response.

Corporate Developments

New Management Structure as Advanced Stage Pipeline Moves Toward Commercialization—Effective June 30, 2023, executive changes go into effect to support the Company’s continued success. Motti Farbstein will lead Can-Fite as Chief Executive Officer and continue to serve as its Chief Financial Officer. Dr. Pnina Fishman, Can-Fite’s Scientific Founder, will move from her position as CEO to become Executive Chairman of the Board as well as continuing to serve as Chief Scientific Officer.

Raised $7.5 Million—In January 2023, Can-Fite raised $7.5 million through a concurrent registered direct offering and private placement. The Company’s cash and equivalents on March 31, 2023 was $12.4 million and is expected to cover all clinical development programs and general and administrative expenses for more than a year from the date of this press release.

"During 2023 we plan to increase our efforts towards establishing additional distribution deals and partnerships. We continue to make progress with our two main indications, liver cancer and psoriasis, as we open additional avenues with niche indications based on evidence of the efficacy and safety of our drugs," stated Can-Fite CEO Dr. Pnina Fishman.

Financial Results

Revenues for the three months ended March 31, 2023 were $0.19 million, a decrease of $0.01 million, or 4.40%, compared to $0.20 million for the three months ended March 31, 2022. The decrease in revenues is considered to be immaterial.

Research and development expenses for the three months ended March 31, 2023 were $2.06 million, an increase of $0.24 million, or 13.17%, compared to $1.82 million for the three months ended March 31, 2022. Research and development expenses for the first quarter of 2023 comprised primarily of expenses associated with the completion of the Phase 3 study of Piclidenoson for the treatment of psoriasis and two ongoing studies for Namodenoson, a Phase 3 study in the treatment of advanced liver cancer and a Phase 2b study for NASH. The increase is primarily due to an increase in expenses associated with Namodenoson.

General and administrative expenses for the three months ended March 31, 2023 were $0.84 million an increase of $0.09 million, or 12.33%, compared to $0.75 million for the three months ended March 31, 2022. The increase is primarily due to the increase in travel expenses and increase in accrued bonuses to the Company’s employees. We expect that general and administrative expenses will remain at the same level through 2023.

Financial income, net for the three months ended March 31, 2023 was $0.16 million compared to finance expense, net of $0.06 million for the three months ended March 31, 2022. The increase in financial income, net was mainly due to exchange rate differences which in 2023 was recorded as income and in 2022 was recorded as expense and revaluation of our short-term investment which in 2023 was recorded as income and in 2022 was recorded as expense.

Net loss for the three months ended March 31, 2023 was $2.55 million compared with a net loss of $2.43 million for the three months ended March 31, 2022. The increase in net loss for the three months ended March 31, 2023 was primarily attributable to an increase in research and development expenses which was partly offset by an increase in finance income, net.

As of March 31, 2023, Can-Fite had cash and cash equivalents and short term deposits of $12.4 million as compared to $7.98 million at December 31, 2022. The increase in cash during the three months ended March 31, 2023 is due to the issuance of share capital and warrants which was offset by ongoing operations of the Company.

The Company’s consolidated financial results for the three months ended March 31, 2023 are presented in accordance with US GAAP Reporting Standards.

KRAS G12V-A11 (MDG2011)
KRAS G12V-A03 (MDG2012)
KRAS G12D-A11 (MDG2021)

Neoantigens are tumor-specific antigens (TSA) and play a critical role in the growth of tumors. These mutations are found in many solid tumors and their prevalence varies depending on the cancer type. KRAS mutations are widely recognized as the most common oncogene mutations in difficult-to-treat solid tumors existing in ~30% of solid tumors, such as pancreatic, colorectal, endometrial and non-small-cell lung cancer. Global incidence of solid tumors expressing KRAS mutations is estimated to be in excess of 300,000 patients.

"Our pipeline expansion into neoantigens with multiple KRAS targets represents a major advance in our pursuit to develop best-in-class TCR-T therapies for patients suffering from difficult-to-treat solid tumors," said Dr. Selwyn Ho, Chief Executive Officer at Medigene. "We are delighted that this latest milestone continues to validate Medigene’s proprietary end-to-end platform as the basis for our highly specific, sensitive and potentially safer TCRs with optimal affinity. These TCRs will be combined with the PD1-41BB and/or the CD40L-CD28 costimulatory switch receptors to enhance the proliferation and persistence of the TCR-T cells and to help mitigate the immunosuppressive effects of the tumor microenvironment."

Dr. Ho continued, "We confirm our guidance to announce the first lead candidate for MDG10XX, which has been renamed as MDG2011, in Q3 this year and expect to announce new TCRs in the near future as we build the broadest KRAS library possible."

R&D Event

The Company will host an R&D Event to discuss the pipeline expansion and the evolution of its end-to-end platform on Tuesday, June 20, 2023, at 10:00 am ET. A Q&A session will follow the formal presentations and discussions.
