## Exhibit 99.1

**Exhibit 99.1**

**Scientific Publication of Can-Fite and Vetbiolix Validates Piclidenoson's Potential in the Multi-Billion Dollar Canine Osteoarthritis Market**

Ramat Gan, Israel, May 18, 2026 (GLOBE NEWSWIRE) -- 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, today announced publication of a peer-reviewed scientific article regarding previously reported positive findings from a study evaluating Piclidenoson for the treatment of canine osteoarthritis. The article abstract, titled *"Piclidenoson, an A3 Adenosine Receptor Agonist, Improves Clinical Signs in Dogs with Osteoarthritis"* was published in the peer-reviewed journal *Frontiers in Veterinary Science* and is available online.

The study described in the publication demonstrated that oral treatment with Piclidenoson resulted in statistically significant improvement in mobility and pain assessments in dogs suffering from osteoarthritis, while maintaining a favorable safety profile. The study supports the continued development of Piclidenoson as a potential oral disease-modifying therapy for canine osteoarthritis.

Key findings reported in the publication include:

● Significant improvement in Liverpool Osteoarthritis in Dogs (LOAD) scores in dogs treated with Piclidenoson at 500 µg/kg BID

● Significant reduction in pain scores measured by the Visual Analog Scale (VAS)

● Significant reduction in veterinarian-assessed lameness and pain

● Favorable safety profile with no serious treatment-related adverse events reported

● Data supporting Piclidenoson's potential as a novel oral therapy for canine osteoarthritis

Piclidenoson is being developed for veterinary indications by Vetbiolix under a licensing agreement with Can-Fite potentially valued at up to $325 million in upfront, milestone, and royalty payments. Vetbiolix is currently conducting an advanced Phase 2 clinical study evaluating Piclidenoson in dogs with osteoarthritis.

Prof. Pnina Fishman, Chairperson and Chief Scientific Officer of Can-Fite, stated,"Publication of these findings in a peer-reviewed scientific journal represents important external validation of Piclidenoson's therapeutic potential in canine osteoarthritis. We believe the data demonstrate the potential of Piclidenoson to provide a safe and effective oral treatment option for dogs suffering from this highly prevalent disease while further supporting the commercial opportunity of our collaboration with Vetbiolix."

Canine osteoarthritis is one of the most common chronic diseases affecting dogs worldwide and represents a significant and growing veterinary market. Current treatment options are limited and are often associated with safety and tolerability concerns during long-term use.
