Data Reported by Can-Fite Veterinary Partner Vetbiolix who already exercised its option for a full license deal worth $325M Ramat Gan, Israel, Oct. 18, 2024 (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 its veterinary partner Vetbiolix reported positive final results from the osteoarthritis multicenter clinical study in dogs treated with Piclidenoson. Vetbiolix, Can-Fite’s veterinary commercialization partner, which is covering all costs associated with veterinary clinical development, successfully concluded the full study. Vetbiolix already exercised its option to enter into a full in-license agreement with Can-Fite and is obligated to pay Can-Fite an upfront payment, milestone payments and royalties on sales upon regulatory approval, summing up to projected income of $325M to Can-Fite over the next 10 years. The study looked at the effect of 90 days treatment with Piclidenoson at 100 μg/kg and 500 μg/kg twice daily orally in dog patients with osteoarthritis. Including all evaluable patients, the primary objective was the Liverpool OsteoArthritis in Dogs (LOAD) questionnaire for the assessment of symptoms severity evaluated on dog’s mobility. The secondary objectives included Visual Analog Scale (VAS) for pain assessment by pet parents and Numerical Rating Score (NRS) for (i) lameness and (ii) pain assessment by the veterinarian. The study reached the primary and secondary endpoints with a dose and time dependent inhibitory effect of Piclidenoson on LOAD and VAS, together with a favorable trend on NRS scores, demonstrating significant improvement in clinical status and decrease in pain utilizing the 500 µg/kg dose. The canine osteoarthritis market is projected to reach $3 billion by 2028. There is a clear need in the market for a safe and effective canine osteoarthritis drug. Current treatments for canine osteoarthritis include oral non-steroidal anti-inflammatory drugs (NSAIDs), which only treat symptoms and carry significant harmful side effects, and an injectable disease-modifying osteoarthritis drug (DMOAD) that targets the progression of the disease. “The final data from the osteoarthritis study are very encouraging and this veterinary indication offers Can-Fite the opportunity to get Piclidenoson onto the market faster to benefit canine, and potentially contribute to near-term revenues.

STOCKHOLM, April 25, 2024 /PRNewswire/ -- Medivir AB (NASDAQ: MVIR) (STO: MVIR) , a pharmaceutical company focused on developing innovative treatments for cancer in areas of high unmet medical need, announced today that its selective cathepsin K inhibitor, MIV-711, has been granted Rare Pediatric Disease Designation (RPDD) as well as Orphan Drug Designation (ODD) for the treatment of Legg-Calvé-Perthes Disease (LCPD). The FDA defines a rare pediatric disease as a serious or life-threatening disease in which the disease manifestations primarily affect individuals aged from birth to 18 years of age. Pediatric diseases recognized as "rare", affect fewer than 200,000 people in the United States. With a RPDD, MIV-711 qualifies to receive fast track review and upon marketing approval in LCPD, the Company may be eligible to receive a Priority Review Voucher from the FDA. The voucher can be redeemed to receive priority review for any subsequent marketing application or may be sold to another company for their use. - "LCPD is a disease, with a significant impact on daily life as well as risk for long-term sequalae, for which there are no available effective treatments. Children with LCPD are more likely to suffer from obesity and depression due to the forced immobility as a consequence of the disease. In more than half of the children, the affected leg becomes shorter than the healthy leg and about 50% end up with a deformed hip joint where ultimately osteoarthritis develops. We are delighted that MIV-711 has been granted RPDD by the FDA with the potential to become the first approved treatment option. We see partnership as an attractive way to move forward with MIV-711 to ensure speed of development," said Jens Lindberg, CEO of Medivir. To gain RPDD, there must be supportive data suggesting that the drug may be effective in the disease. MIV-711 has shown, in an LCPD-specific animal model, the ability to prevent femoral head deformity and positive impact on biomarker of bone degradation without negatively impacting normal bone formation. Similarly, clinical studies have shown that MIV-711 prevents bone degradation in patients with osteoarthritis, further supporting the potential clinical benefit in LCDP. Cathepsin K is the main cysteine protease involved in bone resorption and cartilage degradation by osteoclasts, through the breakdown of key bone matrix proteins. Cathepsin K inhibition protects the damaged bone by reducing bone resorption and promoting bone formation, thereby addressing the key mechanisms causing pathological changes in LCPD, with potential to minimize long-term negative effects. Selective inhibition of cathepsin K has the potential to provide clinical benefit in diseases characterized by excessive bone resorption, including additional pediatric bone disorders.

E-mail: [email protected] About Legg-Calvé-Perthes Disease Legg-Calvé-Perthes disease (LCPD) is a childhood hip disorder initiated by a disruption of blood flow to the head of the femur. Due to the lack of blood flow, the bone dies (osteonecrosis or avascular necrosis) and stops growing. Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which leads to a loss of bone mass and a weakening of the femoral head. The condition is most commonly found in children between the ages of 4 and 8, but it can occur in children between the ages of 2 and 15. It is estimated to affect about 10 in 100.000 children per year in the USA. It results in permanent deformity of the femoral head in many children, which increases the risk of developing osteoarthritis in adults. About MIV-711 MIV-711 is a potent and selective inhibitor of cathepsin K, the principal protease involved in breaking down collagen in bone and cartilage. It has been shown to slow, stop or reverse the progressive degeneration of joints affected by osteoarthritis. By inhibiting cathepsin K and increased/excessive activity of osteoclasts, MIV-711 has the potential to prevent degradation of bone and cartilage and counteract the osteonecrosis induced by lack of blood flow, to prevent femoral head deformity and long-term negative effects as well as positively impact Quality of Life. About Medivir Medivir develops innovative drugs with a focus on cancer where the unmet medical needs are high. The drug candidates are directed toward indication areas where available therapies are limited or missing and there are great opportunities to offer significant improvements to patients. Medivir is focusing on the development of fostroxacitabine bralpamide (fostrox), a smart, targeted chemotherapy designed to selectively treat liver cancer cells and to minimize side effects. Collaborations and partnerships are important parts of Medivir's business model, and the drug development is conducted either by Medivir or in partnership. Medivir's share (ticker: MVIR) is listed on Nasdaq Stockholm's Small Cap list. . This information was brought to you by Cision The following files are available for download: SOURCE Medivir

Craniosynostosis, the premature fusion of the top of the skull in infants, is caused by an abnormal excess of a previously unknown type of bone-forming stem cell, according to a preclinical study. Craniosynostosis, the premature fusion of the top of the skull in infants, is caused by an abnormal excess of a previously unknown type of bone-forming stem cell, according to a preclinical study led by researchers at Weill Cornell Medicine. Craniosynostosis arises from one of several possible gene mutations, and occurs in about one in 2,500 babies. By constricting brain growth, it can lead to abnormal brain development if not corrected surgically. In complex cases, multiple surgeries are needed. In the study, which appears Sept. 20 in Nature, the researchers examined in detail what happens in the skull of mice with one of the most common mutations found in human craniosynostosis. They found that the mutation drives premature skull fusion by inducing the abnormal proliferation of a type of bone-making stem cell -- the DDR2+ stem cell -- that had never been described before. "We can now start to think about treating craniosynostosis not just with surgery but also by blocking this abnormal stem cell activity," said study co-senior author Dr. Matt Greenblatt, an associate professor of pathology and laboratory medicine at Weill Cornell Medicine and a pathologist at NewYork-Presbyterian/Weill Cornell Medical Center. The other co-senior author of the study was Dr. Shawon Debnath, a research associate in the Greenblatt laboratory. In a study published in Nature in 2018, Drs. Debnath and Greenblatt and their colleagues, described the discovery of a type of bone-forming stem cell they called the CTSK+ stem cell. Because this type of cell is present in the top of the skull, or "calvarium," in mice, they suspected that it has a role in causing craniosynostosis. In the new study, they investigated that possibility by engineering mice in which CTSK+ stem cells lack one of the genes whose loss of function causes craniosynostosis. They expected that the gene deletion somehow would induce these calvarial stem cells to go into bone-making overdrive. This new bone would fuse the flexible, fibrous material called sutures in the skull that normally allow it to expand in infants. "We were surprised to find that, instead of the mutation in CTSK+ stem cells leading to these stem cells being activated to fuse the bony plates in the skull as we expected, mutations in the CTSK+ stem cells instead led to the depletion of these stem cells at the sutures -- and the greater the depletion, the more complete the fusion of the sutures," Dr. Debnath said. The unexpected finding led the team to hypothesize that another type of bone-forming stem cell was driving the abnormal suture fusion. After further experiments, and a detailed analysis of the cells present at fusing sutures, they identified the culprit: the DDR2+ stem cell, whose daughter cells make bone using a different process than that utilized by CTSK+ cells. The team found that CTSK+ stem cells normally suppress the production of the DDR2+ stem cells. But the craniosynostosis gene mutation causes the CTSK+ stem cells to die off, allowing the DDR2+ cells to proliferate abnormally. To investigate these stem cells in human tissue, the team formed a collaboration with craniosynostosis surgeon Dr. Caitlin Hoffman, neurogeneticist Dr. Elizabeth Ross, and neuropathologist Dr. David Pisapia, all at Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center; and craniosynostosis surgeon Dr. Thomas Imahiyerobo of Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian/Columbia University Irving Medical Center. The researchers found the human versions of DDR2+ stem cells and CTSK+ stem cells in calvarial samples from craniosynostosis surgeries -- underscoring the likely clinical relevance of their findings in mice. The findings suggest that inappropriate DDR2+ stem cell proliferation in the calvarium, in infants with craniosynostosis-linked gene mutations, could be treated by suppressing this stem cell population, through mimicking the methods that CTSK+ stem cells normally use to prevent expansion of DDR2+stem cells. The researchers found that the CTSK+ stem cells achieve this suppression by secreting a growth factor protein called IGF-1, and possibly other regulatory proteins. "We observed that we could partly prevent calvarial fusion by injecting IGF-1 over the calvarium," said study first author Dr. Seoyeon Bok, a postdoctoral researcher in the Greenblatt laboratory. "I can imagine DDR2+ stem cell-suppressing drug treatments being used along with surgical management, essentially to limit the number of surgeries needed or enhance outcomes," Dr. Greenblatt said. In addition to treatment-oriented research, he and his colleagues now are looking for other bone-forming stem cell populations in the skull. "This work has uncovered much more complexity in the skull than we ever imagined, and we suspect the complexity doesn't end with these two stem cell types," Dr. Greenblatt said.
