• Q1 2022: Psoriasis Phase III Data & Commencement of Enrollment in Phase IIb NASH   
• H1 2022: Commencement of Enrollment in Phase III Liver Cancer

Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE: CFBI), a biotechnology company advancing a pipeline of proprietary small molecule drugs that address inflammatory, cancer and liver diseases, today issued a Letter to Shareholders from its Chief Executive Officer, Dr. Pnina Fishman.

Dear Can-Fite Shareholders,

Beginning in the first quarter of 2022, we expect several significant and value-driving events during the calendar year. We are building upon the solid progress achieved in 2021 which included the completion of a 400-patient Phase III psoriasis study, the design, preparation, and clearance to commence our Phase III liver cancer and Phase II NASH studies, as well as several inventions and patents.

Topline Phase III Psoriasis Data Expected Q1 2022 – Our Comfort™ Phase III study of Piclidenoson enrolled and treated approximately 400 patients with moderate to severe plaque psoriasis. In the first quarter, we expect to announce results from the first 16 weeks of treatment, with the primary endpoint of the study being a statistically significant improvement in achieving a PASI score of 75 in Piclidenoson treated patients vs. placebo. Later in 2022, we expect to announce the study’s secondary endpoint at 32 weeks of treatment which is non-inferiority of Piclidenoson vs. Otezla. The study has four treatment arms: Piclidenoson 2 mg, Piclidenoson 3 mg, Otezla®, and placebo.

Should the topline results confirm Piclidenoson’s efficacy at 16 weeks as compared to placebo, we believe this would be a significant value-driving event. Piclidenoson has already been out-licensed to distribution partners in some European countries, Canada, South Korea, and China through agreements that include milestones payments, and we believe that positive results would trigger high interest in Piclidenoson in other major healthcare markets in which we are currently talking with potential partners.

Following 32 weeks of treatment, if Piclidenoson proves non-inferior to Otezla, we believe this would be a significant event in the psoriasis treatment market, as Piclidenoson and Otezla are both oral drugs in a market dominated by injection-based biologics. We believe it is Otezla’s oral dosing advantage that has led to the drug capturing robust market share and being acquired by Amgen for $13 billion in 2019.

Phase IIb NASH Study Expected to Commence Patient Enrollment in Q1 2022 - The study will enroll 140 patients with biopsy-confirmed NASH with a primary endpoint to evaluate the efficacy of Namodenoson as compared to placebo, as determined by a histological endpoint. Patients will be randomly assigned in a 2:1 ratio to oral doses of Namodenoson 25 mg or placebo every 12 hours for 36 weeks. There is currently no FDA approved treatment for NASH, an urgent unmet need that is a leading cause of liver transplants.

Patient Enrollment Expected to Commence in Pivotal Phase III Liver Cancer Study H1 2022 – In December, we announced that a prior Phase II liver cancer study patient who continues to be treated with Namodenoson has survived five years and cleared all cancer lesions. We see this as a very positive sign as we expect to commence enrollment in the first quarter of 2022. Approximately 450 patients diagnosed with hepatocellular carcinoma (HCC) and underlying Child Pugh B7 (CPB7) who have not responded to other approved therapies will be enrolled through clinical sites worldwide. Patients will be randomized to oral treatment with either 25 mg Namodenoson or matching placebo given twice daily. The primary efficacy endpoint of the trial is overall survival. An interim analysis will be conducted by an Independent Data Monitoring Committee after 50% of patients are enrolled.

While several approved therapies exist for liver cancer, advanced patients often become unresponsive to treatment. With its liver protective properties, Namodenoson helped CPB7 patients who were unresponsive to approved treatments achieve a statistically significant improvement in overall survival as compared to placebo in our prior Phase II study. Namodenoson has been out-licensed to three partners in the indications of liver cancer and NASH in Eastern Europe, South Korea, and China.

We enter 2022 with a strong balance sheet, having raised $10 million in December in addition to the $13.3 million we reported at the end of Q3 2021. While our advanced clinical trials addressing multi-billion markets in psoriasis, liver cancer, and NASH are expected to be our main drivers, we also expect continued development and potential value events from our out-licensing of Piclidenoson to treat osteoarthritis in the veterinary market, as well as development of CF602 in the treatment of erectile dysfunction, and our preclinical work with cannabinoids.

We wish all of you a healthy and happy 2022, and we look forward to sharing significant news during the year.

Sincerely,

Pnina Fishman, Ph.D.
