Can-Fite: New Phase III Psoriasis Data Showing Superior Safety & Improved Efficacy Presented by KOL Dr. Papp at the 31st European Academy of Dermatology

• Dr. Papp: “The safety results on Piclidenoson and its progressive effectiveness over the study period position it as unique among the current treatment options especially given the chronic nature of psoriasis which can necessitate long-term treatment.”
• Piclidenoson has a safety profile similar to placebo and is better tolerated than Otezla®
• Efficacy of Piclidenoson is similar to Otezla in psoriasis patients with severe disease

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, announced today that Dr. Kim A. Papp, MD, PhD, presented new data from the Company’s recently completed Phase III COMFORT™ study at the late-breaking news session of the 31^st European Academy of Dermatology and Venerology (EADV) Congress. Can-Fite previously reported the COMFORT™ study met its primary endpoint with Piclidenoson showing a statistically significant improvement over placebo in psoriasis patients. Piclidenoson is advancing into a pivotal Phase III psoriasis registration trial. The protocol, which is being designed by Dr. Papp, will be submitted to the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for market clearance of Piclidenoson in the treatment of moderate to severe psoriasis.

The following is a summary of key findings presented at EADV on September 10, 2022 in Milan, Italy during Dr. Papp’s presentation titled “Treatment of plaque psoriasis with piclidenoson: Efficacy and safety results from a phase 3 clinical trial (COMFORT)”:

• The COMFORT™ Phase III study met its primary endpoint of superiority vs. placebo at 16 weeks, p=0.037
• Patients treated with Piclidenoson showed an improving progressive response over time, and as psoriasis is a chronic disease that may require long-term treatment, this is an important finding
• Piclidenoson demonstrated an excellent safety profile, overlapping that of the placebo-treated group.
• Piclidenoson had a significantly better tolerability profile than Otezla, as GI-related adverse events were 1% for Piclidenoson vs. 6% for Otezla, nervous system disorders were 0.7% for Piclidenoson, 9.9% for Otezla and 3.3% for the placebo. The discontinuation rate was significantly higher for Otezla vs. Piclidenoson
• In the secondary endpoint of achieving a PASI 75 response (representing a 75% reduction in psoriasis severity) at week 32, in the whole patient population, Piclidenoson was inferior to Otezla; however, in a sub-group analysis of patients who had PASI>25 (more severe psoriasis) at baseline, Piclidenoson had a comparable response to Otezla
• In the secondary endpoint of achieving psoriasis disability index (PDI) response at week 32, Piclidenoson was comparable to Otezla

Dr. Papp commented, “The safety results on Piclidenoson and its progressive effectiveness over the study period position it as unique among the current treatment options especially given the chronic nature of psoriasis which can necessitate long-term treatment.”

Dr. Papps’s presentation was based on a study co-performed by numerous dermatology investigators, in Europe, Israel, and Canada.

Based in Waterloo, Ontario, Canada, Dr. Papp has over 25 years’ experience as a Principal Investigator. Internationally renowned as a Key Opinion Leader in clinical research, Dr. Papp has conducted over 70 international dermatology studies on a wide range of dermatological disorders. The K. Papp Clinical Research center is considered one of the top clinical research centers in the world.

About Piclidenoson

Piclidenoson is a novel, first-in-class, A3 adenosine receptor agonist (A3AR) small molecule, orally bioavailable drug with an excellent safety profile demonstrating evidence of efficacy in Phase II clinical studies. The drug’s mechanism of action entails inhibition of the inflammatory cytokines interleukin 17 and 23 (IL-17 and IL-23) and the induction of apoptosis of patients��� skin cell keratinocytes involved with the disease pathogenicity.

About the Phase III COMFORT™ Study

The COMFORT™ CF101-301PS, is a Phase III randomized, double-blind, placebo- and active-controlled study of the efficacy and safety of daily Piclidenoson (CF101) administered orally in patients with moderate-to-severe plaque psoriasis. The primary objectives of this study are to evaluate the efficacy of oral Piclidenoson 2 mg or 3 mg twice daily (BID) in patients with moderate-to-severe plaque psoriasis, compared with placebo, as determined by the proportion of subjects who achieve a Psoriasis Area and Severity Index (PASI) score response of ≥75% (PASI 75) at Week 16 (superiority); and evaluate the safety of oral Piclidenoson in this patient population. The secondary objectives of this study are to evaluate the efficacy of oral Piclidenoson 2 mg or 3 mg BID, compared with placebo, as determined by the proportion of subjects who achieve, respectively, PASI 50, Physician Global Assessment (PGA) score of 0 or 1, and improvement on the Psoriasis Disability Index (PDI) at Week 16 (superiority); evaluate the efficacy of oral Piclidenoson 2 mg or 3 mg BID, compared with Otezla (apremilast), as determined by the proportion of subjects who achieve PASI 75, PGA score of 0 or 1, PASI 50, and improvement in PDI at Weeks 16 and 32 (non-inferiority); and evaluate the efficacy and safety data for Piclidenoson through the extension period of up to 48 weeks of treatment.
