FDA & EMA approvals for rare genetic diseases are fast and require clinical studies with small number of patients

Ramat Gan, Israel, March 19, 2025 (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 that a Phase II design is completed and preparatory work is undergoing for the initiation of clinical study in the rare genetic disease Lowe Syndrome.

Dr. Franchesca Emma from the Division of Nephrology, Bambino Gesù Children's Hospital - IRCCS Rome Italy, will be the principal investigator of the study. The Phase II open study will enroll 5 patients that will be treated twice daily with 3 mg Piclidenoson for 12 months. The study's primary end point will be the efficacy of Piclidenoson in increasing 99mTc-DMSA renal uptake.
The treatment of this rare genetic disease is based on successful pre-clinical work of Dr. Antonella De Matteis, Professor of Biology, Department of Molecular Medicine and Medical Biotechnology at the University of Naples Federico II, and Program Coordinator of the Cell Biology and Disease Mechanisms at the Telethon Institute of Genetics and Medicine (TIGEM) in Italy. Can-Fite and Fondazione Telethon have signed a collaboration agreement for the clinical development of Piclidenoson for the treatment of Lowe Syndrome, a high medical need with no drug available.

Lowe Syndrome, also known as oculo-cerebro- renal syndrome (OCRL), an X-linked genetic condition occurring almost exclusively in males, is a multisystem disorder characterized by vision problems including clouding of the lenses of the eyes (cataracts) that are present at birth, kidney problems (consisting of urinary loss of proteins and solutes) that usually develop in the first year of life, and brain abnormalities associated with intellectual disabilities, and a life span that rarely exceeds 40 years. Lowe Syndrome prevalence is estimated at approximately 1 in 500,000.

"Having tested thousands of compounds in search of a treatment for Lowe Syndrome, Piclidenoson is the only compound we've found to date that has shown to be effective in pre-clinical studies. Importantly, we observed that Piclidenoson treatment in preclinical models of Lowe syndrome leads to a significant decrease of the urinary loss of proteins," Dr. De Matteis stated. "We chose to investigate Piclidenoson based on the availability of extensive scientific data showing its excellent safety, coupled with efficacy in this disease in pre-clinical studies which involves renal, cerebral, and ocular manifestations."

Can-Fite CSO&Chairperson Dr. Pnina Fishman commented, "We are very much enthusiastic by the breakthrough research of Dr. De Matteis showing that Piclidenoson is efficacious in treating pre-clinical models of Lowe Syndrome. Her impressive results are the basis for implementing Piclidenoson in the treatment of this rare genetic disease". stated Dr. Pnina Fishman, Can-Fite CSO & Chairperson".

About Piclidenoson

Piclidenoson is a robust anti-inflammatory agent, currently being evaluated in a pivotal Phase III psoriasis clinical study under approval of both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

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 and Phase III 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 Fondazione Telethon

Fondazione Telethon ETS is one of the main Italian biomedical charities, founded in 1990 on the initiative of a group of patients suffering from muscular dystrophy. Its mission is to achieve the cure of rare genetic diseases through scientific research of excellence, selected according to the best practices shared internationally. Through a unique method in the Italian panorama, it follows the entire "research chain" dealing with fundraising, selection and funding of projects and the research activity itself carried out in the centers and laboratories of the Foundation. Telethon also develops collaborations with public health institutions and pharmaceutical industries to translate the results of research into therapies accessible to patients. Since its foundation, Telethon has invested more than 660 million euros in research, has funded 2,960 projects with 1,720 researchers involved and 630 diseases studied. To date, thanks to Fondazione Telethon, the first gene therapy with stem cells in the world has been made available, thanks to the collaboration with the pharmaceutical industry. This therapy is intended for the treatment of ADA-SCID, a severe immunodeficiency that compromises the body's defenses from birth. In 2023, Fondazione Telethon became responsible for the production and distribution of the drug to eligible patients in the European Union.

Another gene therapy resulting from Telethon research made available is the one for a serious neurodegenerative disease, metachromatic leukodystrophy. This therapeutic approach is in an advanced stage of development for another immunodeficiency, Wiskott-Aldrich syndrome. Other diseases on which the gene therapy developed by Telethon researchers has been evaluated in patients are beta thalassemia and two metabolic diseases of childhood, mucopolysaccharidosis type 6 and type 1. In addition, within the Telethon institutes a targeted therapeutic strategy is being studied or developed for other genetic diseases, such as hemophilia or various hereditary vision defects. In parallel, the study of basic mechanisms and potential therapeutic approaches for diseases still unanswered continues in all laboratories funded by Telethon.
