CCL26

CHENGDU, China, April 5, 2025 /PRNewswire/ -- Keymed Biosciences Inc. (HKEX: 02162) ("Keymed" or the "Company") today announced that the prestigious medical journal Nature Medicine has published the results from the Phase III trial of its independently developed IL-4Rα antibody stapokibart, for the treatment of moderate-to-severe seasonal allergic rhinitis (SAR). The study, led by Professor Luo Zhang of Beijing Tongren Hospital, Capital Medical University, represents the world's first clinical report on an IL-4Rα-targeted biologic for SAR, underscoring Chinese scientists' pioneering role in allergic rhinitis innovation. The study demonstrated that stapokibart significantly alleviates clinical symptoms and improves quality of life in patients with moderate-to-severe SAR who remained inadequately controlled despite standard therapies. This breakthrough offers a transformative solution to a global health challenge, ushering in a new era of biologic treatments for allergic rhinitis and providing hope to hundreds of millions of patients worldwide. Rapid, potent and sustained control of nasal symptoms: Rapid relief of nasal obstruction：Compared to placebo group, patients in stapokibart group achieved significantly greater improvement in nasal congestion symptom at Day 2. By Day 7, 72% of patients reported clear nasal breathing, with the cumulative response rate rising to 86% at Week 2 and 94% at Week 4. Potent and sustained control of nasal symptoms：Stapokibart demonstrated a 2.7-point reduction in daily reflective total nasal symptom score (rTNSS) from baseline by Day 4, significantly greater than the improvement in the placebo group. Over the 2-week treatment period, stapokibart achieved a 3.6-point reduction in daily rTNSS from baseline, with a least squares (LS) mean difference of -1.3 points vs. placebo (the primary efficacy endpoint). Additionally, 62% of patients achieved mild or no symptom (defined as rTNSS ≤1 point for each symptom); Over the 4-week treatment period, the stapokibart group showed a 4.9-point reduction in daily rTNSS from baseline, with an LS mean difference of -1.7 points vs. placebo. The proportion of patients achieving mild or no nasal symptoms reached 84%. Sustained and significant improvement of ocular symptoms: Stapokibart demonstrated clinically significant reductions in the daily reflective Total Ocular Symptom Score (rTOSS) from baseline, with improvements of 2.6 points at week 2 and 3.7 points at week 4 respectively, both significantly superior to placebo. By Week 2, 62% of patients achieved mild or no ocular symptoms (defined as rTOSS ≤1 point for each symptom), increasing to 94% by Week 4. Significant reduction in levels of type 2 inflammatory biomarkers During the 4-week treatment period, the stapokibart group demonstrated significant reductions in total serum IgE levels and allergen-specific IgE (sIgE) levels against pollen allergens. Additionally, stapokibart reduced type 2 inflammatory biomarker levels in nasal secretions, including cystatin SN (CST1) and eotaxin-3, demonstrating its dual mechanism of action: targeting both the underlying etiology (type 2 inflammation) and symptomatic manifestations of allergic rhinitis. Safety Stapokibart demonstrated a favorable safety profile in patients with seasonal allergic rhinitis. The incidence of treatment-emergent adverse events (TEAEs) was comparable to placebo, and no serious adverse events (SAEs) were reported during the trial. The PHECDA trial pioneered targeted biologic therapy for allergic rhinitis. The results supported the approval of stapokibart—the world's first and only IL-4Rα monoclonal antibody for seasonal allergic rhinitis (SAR)— by China's National Medical Products Administration (NMPA) on February 7, 2025. This breakthrough provides a novel therapeutic option for patients with moderate-to-severe refractory SAR, solidifying Chinese clinical scientists' global leadership in allergic rhinitis research and setting a precedent for future clinical development.

SYDNEY, March 21, 2024 /PRNewswire/ -- Kazia Therapeutics Limited (NASDAQ: KZIA), a biotechnology company specialising in oncology, is pleased to announce that it has entered into an exclusive licensing agreement with Sovargen Co., Ltd, a biotechnology company specializing in central nervous system (CNS) diseases, to develop, manufacture and commercialise paxalisib as a potential treatment of intractable epilepsy in focal cortical dysplasia type 2 (FCD T2) and tuberous sclerosis complex (TSC) disease. The underlying cause of FCD T2 and TSC can be traced back to somatic mutations in the PI3K/Akt/mTOR pathway or mutations in the TSC1 or TSC2 genes, which lead to the overactivation of the mTOR pathway. Paxalisib is an oral dual inhibitor targeting both PI3K and mTOR within this pathway, and it is distinguished by its ability to penetrate the brain. Although FCD T2 and TSC are rare orphan diseases, they represent a high medical unmet need with significant market opportunity. There are currently no approved drugs for patients with FCD T2. Under the agreement, Kazia will receive an upfront payment of US$1.5 million, potential milestone payments of up to US$19 million upon the achievement of development and regulatory milestones, and a percentage of sub-licensing revenues and royalties on net sales of products incorporating paxalisib. The licensing agreement includes all countries worldwide, excluding mainland China, Hong Kong, Macao and Taiwan, which Kazia retains. Kazia CEO Dr. John Friend said: "We are pleased to announce we have exclusively licensed the development, manufacture and commercialization of paxalisib to Sovargen for its potential use in select CNS diseases that are associated with mTORopathy. Kazia's primary focus of paxalisib continues to be oncology, with multiple studies ongoing. Our license with Sovargen provides us the ability to explore the impact of paxalisib outside of our area of expertise where there is substantial patient need and market opportunity. We are enthusiastic about seeing paxalisib's potential explored in these patient populations." Sovargen CEO Cheolwon Park shared his excitement about the collaboration: "The dual inhibition mechanism of paxalisib, coupled with its observed safety pro previous oncology studies, positions us to anticipate initiation of a Phase 2 clinical trial for patients with FCD T2 and TSC in the latter half of 2024. Sovargen has played a pioneering role in identifying the critical link between mTOR hyperactivation due to mTORopathy somatic mutations and epileptic seizures in FCD T2 patients and we have an unwavering dedication to developing effective treatments for these patients."

—Proteomic Analysis of Human Samples Highlights the Unique Role of CCL24 in Activating Key PSC-related Disease Mechanisms Involving Immune Cell Trafficking and HSC Activation, Further Confirming the Potential of Chemomab's CCL24-Neutralizing Antibody CM-101 as a Promising Therapy for PSC— —CM-101 Phase 2 PSC Trial Has Completed Patient Enrollment with Topline Data Readout Targeted for Midyear 2024— TEL AVIV, Israel, Jan. 30, 2024 /PRNewswire/ -- Chemomab Therapeutics Ltd. (Nasdaq: CMMB) (Chemomab), a clinical stage biotechnology company focused on the discovery and development of innovative therapeutics for fibro-inflammatory diseases with high unmet need, today announced publication of proteomic analyses that further demonstrate the unique role of the soluble protein CCL24 in driving pathologies associated with the rare fibrotic liver disease primary sclerosing cholangitis (PSC). The new studies reinforce the extensive existing evidence showing that Chemomab's first-in-class CCL24-neutralizing antibody CM-101 can interrupt these destructive processes. The study, "The Role of CCL24 in Primary Sclerosing Cholangitis: Bridging Patient Serum Proteomics to Preclinical Data" 1 has been published in the current online version of the peer-reviewed journal Cells. "The patient sample and other proteomic analyses reported in this publication add to the large and growing body of data showing that CCL24 is a major driver of PSC pathology, providing more detail about its central role in orchestrating the fibrosis and inflammation underlying PSC progression," said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. "These new data further validating our CCL24 target and the clinical rationale for our CCL24-neutralizing antibody are especially timely as we look forward to our CM-101 Phase 2 topline readout expected midyear, which has the potential to deliver the first significant clinical proof-of-concept of CM-101's therapeutic activity in PSC, a lethal disease with no FDA approved therapies." The studies included advanced proteomic analyses of serum samples from PSC patients and healthy controls to further investigate the involvement of CCL24 in PSC and its association with specific disease-related pathways. They confirmed the exclusive association of CCL24 with fundamental PSC mechanisms, with no similar association seen with two other related proteins (CCL11 and CCL26) sharing the same receptor, emphasizing CCL24's unique potential as a target for PSC therapies. Additional studies showed that CCL24 directly contributes to the development of fibrosis and inflammation in PSC via recruitment of monocytes and neutrophils and activation of hepatic stellate cells (HSCs), a major source of the myofibroblasts that are a key driver of liver fibrogenesis. Notably, an invitro analysis pinpointed a CCL24-dependant proteomic signature in HSCs treated with CCL24 that is capable of stratifying PSC patients based on disease severity, offering promise for future disease activity monitoring. CM-101 is a first-in-class CCL24-neutralizing monoclonal antibody whose dual anti-inflammatory and anti-fibrotic activity has demonstrated disease modifying potential in nonclinical studies of PSC and other fibro-inflammatory disorders. CM-101 has Orphan Drug designation for PSC in the U.S. and the European Union and was recently awarded Fast Track designation by the FDA for the treatment of PSC in adults. About Primary Sclerosing Cholangitis PSC is a rare, progressive liver disease characterized by inflammation and fibrosis (scarring) of the bile ducts that can lead to cirrhosis of the liver, liver failure and death. PSC also increases the risk of various cancers, which account for about half of PSC-related mortality. PSC affects an estimated 30,000 patients in the U.S. and about 80,000 worldwide. The underlying cause of PSC is unknown, but about 75% of patients also have inflammatory bowel disease. Currently there are no approved therapies for PSC. Liver transplantation is common in advanced cases, but even then, PSC re-occurs in about 20% of transplanted patients. There is a high unmet need for therapeutic options to address the symptoms and modify the progression of this devastating illness. 1 Greenman, R.; Snir, T.; Katav, A.; Aricha, R.; Mishalian, I.; Hay, O.; Frankel, M.; Lawler, J.; Saffioti, F.; Pinzani, M.; et al.
