Can-Fite BioPharma (NYSE: CANF) launches first Piclidenoson trial in Lowe syndrome
Rhea-AI Filing Summary
Can-Fite BioPharma Ltd. launched its first clinical program of Piclidenoson in Lowe syndrome, submitting a Phase 2 study protocol to Bambino Gesù Children’s Hospital in Rome. The open-label, single-center trial will treat 5 adult patients with genetically confirmed Lowe syndrome using oral Piclidenoson twice daily for six months.
The primary endpoint is improvement in renal uptake of 99mTc-DMSA, with secondary endpoints covering urinary biomarkers, Fanconi syndrome parameters, and safety. The program is conducted under a collaboration with Fondazione Telethon. Piclidenoson is already in a pivotal Phase 3 psoriasis study, while Namodenoson and CF602 advance other oncology and inflammatory indications in Can-Fite’s pipeline.
Positive
- None.
Negative
- None.
Filing Explained
Although the release calls the program a launch, the concrete milestone disclosed is submission of the Phase 2 protocol; the filing therefore places it at the protocol-submission stage rather than a disclosed treatment-start stage.

Exhibit 99.1
Can-Fite Launches First Clinical Program for Piclidenoson in the Rare Genetic Disease Lowe Syndrome
Phase 2 clinical study
protocol submitted; Small Phase 2 study designed to support regulatory
interactions and potential registration upon positive results
Ramat Gan, Israel, Aug. 03, 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 the submission of a Phase 2 clinical study protocol to Bambino Gesù Children’s Hospital in Rome, Italy, for the first clinical evaluation of Piclidenoson in patients with Lowe syndrome, a rare inherited genetic disorder with no approved disease-modifying therapies. The study will be led by Prof. Francesco Emma, an internationally recognized expert in inherited kidney diseases.
Lowe syndrome is a rare X-linked multisystem genetic disorder caused by mutations in the OCRL gene, resulting in severe renal, neurological, and ocular manifestations. The renal disease is characterized by progressive proximal tubular dysfunction leading to Fanconi syndrome, chronic kidney disease, and eventual kidney failure. Current management is supportive, and no approved therapy addresses the underlying disease mechanism.
Piclidenoson was selected for clinical evaluation based on compelling preclinical studies demonstrating restoration of OCRL-dependent cellular function found by 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.
The Phase 2 study is an open-label, single-center clinical trial designed to evaluate the efficacy and safety of oral Piclidenoson administered twice daily for six months in 5 adult patients with genetically confirmed Lowe syndrome. The primary endpoint is improvement in renal uptake of 99mTc-DMSA as a measure of proximal tubular reabsorption capacity, with secondary endpoints evaluating urinary biomarkers of tubular function, Fanconi syndrome parameters, and safety.
“The initiation of our first clinical program in Lowe syndrome represents an important milestone for Can-Fite,” said Motti Farbstein, CEO of Can-Fite BioPharma. “Supported by compelling preclinical data, this focused Phase 2 pilot study is designed to facilitate discussions with regulatory authorities regarding the clinical development and potential registration pathway for Piclidenoson in Lowe syndrome. We are pleased to collaborate with Prof. Francesco Emma and his team at Bambino Gesù Children’s Hospital on this important program.”
About Piclidenoson
Piclidenoson is a robust anti-inflammatory agent, currently being evaluated in a pivotal Phase 3 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.
