The publication, entitled "Synthesis and characterization of soquelitinib a selective ITK inhibitor that modulates tumor immunity," includes a detailed overview of soquelitinib’s mechanism of action – suppressing Th2 and Th17 cytokine production and sparing Th1 cytokines – that serves as a novel approach to cancer immunotherapy, both as a single agent and in combination with immune checkpoint inhibitors. The data also shows that soquelitinib increases effector function of cytotoxic CD8 positive T cells and leads to an increase in memory T cells with enhanced effector function.

"We continue to build awareness of the unique potential of soquelitinib and ITK inhibition as a novel therapy that modulates parallel signaling pathways in the immune system for the treatment of oncology and immune diseases," said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. "This publication in npj Drug Discovery highlights foundational work characterizing key properties and mechanisms of soquelitinib conducted at Corvus and with academic collaborators, and we are excited to now be in clinical development for PTCL and atopic dermatitis, along with a broad range of additional opportunities for soquelitinib and our next-generation ITK inhibitors."

The published research was a result of collaborations between scientists at Corvus and researchers at the University of Michigan, The Ohio State University, Peking University, Stanford University and Angel Pharmaceuticals Co., Ltd. The publication is available online at the Nature website and on the Publications and Presentations page of the Corvus website.

Corvus is currently developing soquelitinib and its next-generation ITK inhibitors for oncology and immune diseases. The Company is enrolling patients in a registrational Phase 3 clinical trial in patients with relapsed peripheral T cell lymphoma (PTCL) and a randomized, placebo-controlled Phase 1 clinical trial in patients with moderate to severe atopic dermatitis. The Company plans to initiate a Phase 1 clinical trial of soquelitinib in patients with solid tumors.

8 Years Survival with Complete Cure for a Patient with Advanced Liver Cancer Being Treated with Can-Fite’s Namodenoson Drug

On December 4, 2024 Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE: CANF), a biotechnology company advancing a pipeline of proprietary small molecule drugs that address oncological and inflammatory diseases, reported that a patient currently treated with Namodenoson in a compassionate use program in Can-Fite’s Phase II Liver Cancer Study has an overall survival time of 8 years with a complete response (Press release, Can-Fite BioPharma, DEC 4, 2024, View Source [SID1234648786]).

The patient, who suffered from advanced liver cancer was enrolled in the former Can-Fite Phase II study, continue to be treated with Namodenoson, and has now an overall survival of 8 years, with disappearance of ascites, normal liver function, good quality of life and is defined as a long term complete response.

Can-Fite is currently enrolling patients in Israel, Europe and the US for a pivotal Phase III clinical study for patients with advanced HCC as a 2nd or 3rd line treatment and Namodenoson is administered twice daily orally. The study protocol has been agreed upon with U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA).

Namodenoson has Orphan Drug status with both the FDA and EMA, as well as Fast Track Status with the FDA for the treatment of HCC. A compassionate use program has been ongoing in Israel and Romania.

"With a very favorable safety profile and anti-cancer effect of Namodenoson, we are now enrolling patients for the pivotal Phase III clinical study where we expect to prolong patients’ overall survival, and see a response similar to that of the patient who has now been treated with Namodenoson for 8 years. The uniqueness of Namodenoson which specifically acts against the tumor cells and protects the normal liver cells, is the rationale for the conductance of the current trial," stated Prof. Salomon Stemmer, a leading key opinion leader, at the Institute of Oncology, Rabin Medical Center, Israel.

According to the American Cancer Society, liver cancer accounts for more than 700,000 deaths globally each year. HCC is commonly aggressive with poor survival rates. As new drugs that effectively and safely treat HCC are developed and approved, the market for HCC treatments is estimated by Delveinsight to reach $6.1 billion by 2027 for the G8 countries.

About Namodenoson

Namodenoson is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). Namodenoson was 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.

About Rhenium (186Re) Obisbemeda

Rhenium (186Re) Obisbemeda is a novel injectable radiotherapy specifically formulated to deliver direct targeted high-dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. Rhenium (186Re) Obisbemeda has the potential to reduce off-target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. Rhenium (186Re) Obisbemeda is being evaluated for the treatment of recurrent glioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT).
