- Initiation of Upcoming Phase 1a/1b Clinical Trial Expected in the Second Quarter of 2025 - WAYNE, Pa, April 22, 2025 (GLOBE NEWSWIRE) -- Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a clinical-stage biopharmaceutical company focused on developing novel product candidates for immuno-inflammatory diseases, today announced that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for a Phase 1a/1b clinical trial of ATI-052, a potential best-in-class bispecific anti-TSLP/IL-4R monoclonal antibody. “Therapeutic innovation is at the core of the important work we do at Aclaris, and bispecific antibodies represent a groundbreaking innovation in immunotherapy that we believe will evolve the therapeutic armamentarium in a variety of settings,” said Dr. Hugh Davis, Aclaris’ President and Chief Operating Officer. “Key to our license agreement with Biosion, Inc. were the rights to ATI-052, a potential best-in-class investigational bispecific antibody that exhibits a high binding affinity to, and dual blockade of, both the TSLP ligand and the IL-4 receptor, and as such inhibits a key central proinflammatory pathway. Developing bispecific antibodies for immuno-inflammatory disorders is of significant interest to Aclaris, and the clearance of the ATI-052 IND by the FDA is an important milestone in that regard.” The randomized, blinded, placebo-controlled, Phase 1a/1b clinical trial will evaluate single and multiple ascending doses of ATI-052 followed by a proof-of-concept portion in an undisclosed indication. The Company expects to initiate the trial in the second quarter of 2025. Bispecific antibodies are engineered to have two distinct binding domains that can bind to two targets simultaneously. This dual binding and pathway inhibition potentially enhances efficacy over traditional monoclonal antibodies, with broad applications for the potential treatment of many immune-modulated diseases. About Investigational New Drug Applications (INDs) An IND application is a request submitted to the FDA seeking permission to test a new drug in humans. The application includes detailed information about the investigational drug, its composition, pharmacology and toxicology data from preclinical studies, proposed clinical trial protocols, and information on manufacturing and quality control. Organizations can initiate a clinical trial in the U.S. only with IND clearance from the FDA. About ATI-052 ATI-052 is an investigational, potential best-in-class anti-TSLP/IL-4R bispecific monoclonal antibody being developed to treat certain immuno-inflammatory diseases. ATI-052 targets thymic stromal lymphopoietin (TSLP) and interleukin-4 receptor (IL-4R) that blocks both the upstream TSLP receptor signal transduction and downstream IL-4R activation which inhibits both IL-4 and IL-13 signaling, thereby inhibiting this central proinflammatory pathway and potentially offering enhanced efficacy through dual pathway inhibition. ATI-052 utilizes the same TSLP antigen-binding fragment (Fab) region as bosakitug (ATI-045), Aclaris’ investigational anti-TSLP monoclonal antibody, but is engineered to bind more tightly to the neonatal Fc receptor (FcRn), potentially extending its half-life. ATI-052 has the potential to treat a variety of atopic, immunologic and respiratory diseases. Aclaris has the exclusive worldwide rights to ATI-052, excluding Greater China. About Aclaris Therapeutics, Inc. Aclaris Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing a pipeline of novel product candidates to address the needs of patients with immuno-inflammatory diseases who lack satisfactory treatment options. The company has a multi-stage portfolio of product candidates powered by a robust R&D engine.

Based on the latest nasal polyps results, Leerink Partners analysts stood by their $4.3 billion Tezspire sales projection for Amgen by 2030. Already billed as a potential blockbuster, Amgen and AstraZeneca’s Tezspire has turned in strong clinical data in chronic rhinosinusitis with nasal polyps (CRSwNP). Tezspire showed numerically better efficacy results in CRSwNP compared with two prominent rivals in the three drugs' separate studies. However, separate teams of analysts at William Blair and Leerink Partners stopped short of handing Tezspire the crown in the indication, citing trial design differences that likely play into the cross-trial comparisons.As Amgen and AZ previously announced, Tezspire significantly improved total nasal polyp score (NPS) and nasal congestion score (NCS) in patients with CRSwNP compared with placebo after 52 weeks in the phase 3 Waypoint study.On NPS, a metric with a range of 0 to 8, treatment with Tezspire led to a placebo-adjusted average improvement of nearly 2.07 points, according to results presented at the joint conference of the American Academy of Allergy, Asthma & Immunology and the World Allergy Organization. On NCS, which is scored between 0 and 3, Tezspire performed about 1.03 points better than placebo.The drug also nearly eliminated the need for future surgery and corticosteroid use, Joseph Han, M.D., from the Eastern Virginia Medical School and a co-primary investigator of the Waypoint trial, highlighted in a statement Saturday.Tezspire, which is already approved in severe asthma, didn’t raise any new safety signals, according to investigators. Serious adverse events occurred in 4.9% of Tezspire patients, versus 5.9% in the placebo group.Tezspire’s efficacy numbers came in slightly above Dupixent’s figures from two of its own phase 3 trials, Sinus-24 and Sinus-52. Results from those studies in 2019 enabled the Sanofi and Regeneron antibody to become the first treatment approved by the FDA in inadequately controlled CRSwNP. Dupixent’s 52-week placebo-adjusted difference was 1.8 on NPS and 0.9 on NCS.What’s more, the Tezspire data also look better than results for GSK’s depemokimab. In the phase 3 Anchor-1 and Anchor-2 trials, depemokimab’s 52-week NPS difference amounted to 0.7 points versus placebo. Rather than NCS, the GSK trials used a different co-primary endpoint called verbal response scale to measure nasal obstruction.Based on the results, the Leerink team stood by its $4.3 billion Tezspire sales projection for Amgen by 2030, compared with the consensus estimate of $3 billion. CRSwNP is marked by persistent inflammation of the nasal mucosa, accompanied by nasal polyps, which can block the nose. The inflammatory disease represents a big market, as Dupixent has already achieved blockbuster annual sales in the indication alone, Marion McCourt, commercial chief at Regeneron, said during a conference call last month.The three biologics work in different ways. Tezspire blocks thymic stromal lymphopoietin (TSLP), while depemokimab targets IL-5 and Dupixent inhibits the IL-4/13 axis.“With its first-in-class mode of action, targeting TSLP at the top of the inflammatory cascade, the data add to the body of evidence that [Tezspire] can transform care for patients with epithelial-driven inflammatory diseases,” Sharon Barr, AZ’s head of biopharmaceuticals R&D, said in a statement Saturday.The William Blair analysts said the results “hint at best-in-disease therapy." Importantly, though, both sets of analysis said trial design differences may have impacted the drugs’ relative trial performances.Flagging several nuances in enrollment criteria, Leerink analysts suggested that compared with the Dupixent trials, “Tezspire enrolled a more selective group regarding respiratory comorbidities, but a broader population in terms of prior surgery.”To enroll in Tezspire’s Waypoint trial, patients were required to meet certain bars on NCS and the sino-nasal outcome test (SNOT-22), which measures the symptoms and consequences of rhinosinusitis. GSK’s Anchor trials, which didn’t implement such restrictions, enrolled a “somewhat milder population,” the William Blair team noted.Among the three agents, GSK’s depemokimab appears to have the weakest efficacy numbers—not just on the co-primary endpoint of NPS but also on some secondary endpoints such as change in SNOT-22 score. However, William Blair analysts suggested that the drug’s efficacy may be underestimated given the differences in trial populations.As a twice-yearly therapy, depemokimab boasts a long-acting advantage. Tezspire is dosed subcutaneously every month, while Dupixent is given every other week.“As highlighted by the presenter, patient preference shifts to an injectable therapy over daily orals when the treatment interval is as infrequent as every six months, which could lead to modest commercial uptake in some patients if approved,” William Blair analysts said in a Monday note. Han presented both datasets for Tezspire and depemokimab at AAAAI. During the Q&A session, Han recommended that future trials in CRSwNP incorporate baseline thresholds such as SNOT-22 to focus on moderate-to-severe patients, rather than milder patients who were also allowed in GSK’s Anchor studies, according to William Blair.TSLP as a target has lately attracted much interest, partly thanks to the success of Tezspire. Continuing with its long-acting pursuit, GSK last year bought Aiolos Bio and its anti-TSLP candidate, AIO-001, which the British pharma believes may be dosed once every six months. The candidate was originally licensed from China’s Jiangsu Henguri Pharmaceuticals.Also gunning for a twice-yearly anti-TSLP antibody, Windward Bio emerged earlier this year with a $200 million series A led by OrbiMed, Novo Holdings and Blue Owl Healthcare Opportunities, plus a clinical candidate licensed from China’s Kelun-Biotech and Harbour BioMed.Johnson & Johnson’s $850 million acquisition of Proteologix last year also featured an IL-13/TSLP bispecific. And Upstream Bio could report phase 2 CRSwNP data for verekitug, an antibody targeting the TSLP receptor, later this year. 

In January 2025, a series of collaborative agreements were successively reached in the field of antibody-based pharmaceuticals in China: WuXi Biologics partnered with Candid Therapeutics to advance the development of a BCMA, CD20, and CD19 tri-specific antibody therapy through its WuXiBody™ platform. This groundbreaking partnership indicates a new direction for future oncological immunotherapy. Concurrently, Keymed Biomedical's CD38 monoclonal antibody, CM313, was successfully licensed to Timberlyne Therapeutics, further solidifying China's leading position in the treatment of hematological malignancies. These agreements not only demonstrate China's profound expertise in antibody engineering and drug development but also reflect the determination of Chinese enterprises to expand into international markets and seek global development. For instance, Kelun Botai's collaboration with Harbour BioMed on the TSLP monoclonal antibody SKB378/HBM9378 received investment and cooperation from Windward Bio AG, aimed at addressing unmet needs in respiratory diseases such as asthma and chronic obstructive pulmonary disease. Moreover, the collaboration between Simcere Zaiming and AbbVie brings new hope to patients with multiple myeloma. SIM0500, a GPRC5D/BCMA/CD3 tri-specific antibody, with its unique targeting mechanism, is poised to be an innovator in the field. In this wave of international expansion, the international licensing of the bispecific antibody ICP-B02 (CM315) is also noteworthy. InnoCare Pharma and Keymed Biomedical joined hands with Prolium Bioscience to promote the global commercialization of this CD20×CD3 bispecific antibody. This not only challenges traditional cancer treatment methods but also tests China's innovative capabilities and scientific research levels. Through such transnational cooperation, China's biopharmaceutical industry is gradually advancing to the forefront of the world, bringing more treatment options to patients in China and globally. 1.WuXi Biologics and Candid Therapeutics join forces to advance innovative tri-specific antibody therapy  On January 7, 2025, WuXi Biologics and Candid Therapeutics entered into a significant research service collaboration agreement, marking a new phase in the development of innovative therapies. Under the terms of the agreement, Candid will acquire global rights to a tri-specific antibody developed on WuXi Biologics’ WuXiBody™ platform. This antibody, in the preclinical development stage, targets three different antigen sites: BCMA, CD20, and CD19. These targets are carefully chosen to enhance the killing effect on tumor cells via T-cell-mediated immune responses. BCMA (B-cell maturation antigen), highly expressed in multiple myeloma (MM) and other hematologic malignancies, is a key target for treating these diseases. As a member of the tumor necrosis factor receptor superfamily, BCMA is primarily expressed on the surface of malignant and normal plasma cells and is not expressed in essential tissues, making it an ideal treatment target. CAR-T cell therapies targeting BCMA have shown significant efficacy in relapsed or refractory MM patients, with overall response rates from 73% to 100% and complete response rates from 31% to 69%. BCMA signaling pathway1 On the other hand, CD20 and CD19 are antigens broadly and relatively stably expressed on the surface of B cells, playing crucial roles in various B-cell-related cancers like non-Hodgkin's lymphoma (NHL). CD19 is an antigen that remains expressed throughout the B-cell development process and is also highly conserved in most B-cell malignancies. At the same time, CD20 is a marker of mature B cells, used as a target in the treatment of B-cell lymphomas and leukemias. The uniqueness of WuXi Biologics’ tri-specific antibody lies in its ability to bind simultaneously to two different antigens on tumor cells (like CD20 and CD19) and an activation molecule on the surface of T cells (such as BCMA or possibly another co-stimulatory molecule). This multi-binding approach helps to direct T cells close to tumor cells and promote close contact between them, thereby enhancing T-cell-mediated cytotoxicity. Additionally, this tri-targeting could inhibit tumor cells' ability to evade immune surveillance, further increasing the effectiveness of the treatment. Notably, the WuXiBody™ platform's unique advantage is its ability to construct multi-specific antibodies of various valences to meet the biological needs of different projects, thus providing greater flexibility and potential for drug development. The financial terms involved in this collaboration are also notable. WuXi Biologics will receive an undisclosed upfront payment and is eligible for subsequent development and sales milestone payments totaling up to $925 million (approximately RMB 6.78 billion), plus sales royalties post-commercialization. Such a transaction structure not only reflects the partners' confidence in the future market prospects of this tri-specific antibody but also provides WuXi Biologics with substantial economic returns. 2.Keymed Biomedical's CD38 Monoclonal Antibody CM313 On January 10, 2025, Keymed Biomedical (02162.HK) announced a significant agreement involving the exclusive licensing of global rights (excluding mainland China, Hong Kong, Macau, and Taiwan) for their autonomously developed humanized monoclonal antibody CM313 targeting CD38, to Timberlyne Therapeutics. CM313 is an innovative therapeutic agent that targets the CD38 molecule, a glycoprotein highly expressed on the surface of various hematologic tumor cells. As a potential "best-in-class" candidate, CM313 uniquely binds to the CD38 molecule to not only eradicate antibody-secreting cells, including long-lived plasma cells (LLPCs), thereby preventing antibody-mediated platelet destruction but also restoring normal platelet production and function. Furthermore, CM313 has the ability to suppress the activity of immune cells such as monocytes, demonstrating significant potential in treating conditions like relapsed/refractory multiple myeloma, lymphoma, and other autoimmune diseases. CM313 is capable of directly inducing apoptosis in tumor cells and indirectly killing them through mechanisms such as Antibody-Dependent Cellular Cytotoxicity (ADCC), Complement-Dependent Cytotoxicity (CDC), and Antibody-Dependent Cellular Phagocytosis (ADCP). Preclinical studies have shown that CM313 exhibits a therapeutic response rate of up to 95% in adult patients with primary immune thrombocytopenia (ITP) and has displayed favorable safety profiles. These results indicate that CM313 could be an effective treatment option, particularly for patients who are unresponsive or intolerant to conventional therapies. Currently, CM313 is in various stages of clinical trials to evaluate its efficacy and safety across different indications. From a business perspective, this licensing deal marks a significant step for Keymed Biomedical in the international market. Under the terms of the agreement, Keymed Biomedical will receive an upfront payment of $30 million, near-term payments, and become the largest shareholder in Timberlyne, holding 25.79% of its equity. Moreover, upon achieving certain sales and development milestones, Keymed Biomedical is eligible to earn up to an additional $337.5 million in milestone payments, as well as tiered royalties based on sales. Concurrently, Timberlyne has completed a Series A financing round totaling $180 million, supported by prominent investment institutions including Bain Capital Life Sciences and Venrock Healthcare Capital Partners, providing essential financial backing for further research and development of CM313, and affirming high market confidence in the drug's prospects. 3.Kelun Botai and Harbour BioMed join forces, propelling TSLP monoclonal antibody SKB378/HBM9378 towards the global market On January 10, 2025, Kelun Botai and Harbour BioMed jointly announced that they had entered into an important exclusive licensing agreement with Windward Bio AG for the jointly developed anti-thymic stromal lymphopoietin (TSLP) monoclonal antibody SKB378/HBM9378. This drug is a fully human monoclonal antibody targeting the critical TSLP, which functions by inhibiting the TSLP-mediated signaling pathways through blocking the interaction between TSLP and its receptor. TSLP is a cytokine playing a crucial role in the development and progression of various immunological diseases, including asthma and chronic obstructive pulmonary disease (COPD). When TSLP binds to its receptor, it initiates a series of complex downstream signaling cascades involving significant mechanisms such as the JAK-STAT pathway, thereby promoting inflammatory responses. Binding of TSLP to the complex of TSLP receptor (TSLPR) and IL-7Rα activates antigen-presenting cells and promotes the differentiation of naive CD4+ T lymphocytes into Th2 cells, leading to the release of pro-inflammatory cytokines like IL-4, IL-5, and IL-13. Excessive activation of this Th2-type immune response is a key driver of many allergic diseases, such as asthma, atopic dermatitis, and certain autoimmune diseases. In patients with allergic asthma, elevated TSLP levels produced by airway epithelial cells are significantly related to disease severity and decreased lung function. By inhibiting TSLP, SKB378/HBM9378 effectively blocks upstream inflammatory mediators, reduces the release of pro-inflammatory cytokines, alleviates airway inflammation and allergic reactions, and improves patient symptoms and lung function. Functions of TSLP in promoting type 2 responses3 As a novel recombinant fully human monoclonal antibody, SKB378/HBM9378 not only exhibits high specificity and potent biological activity but has also been engineered to have an extended half-life, meaning that patients may require fewer dosing sessions to maintain therapeutic efficacy. Furthermore, in contrast to other drugs of the same type, it employs a subcutaneous injection method, enhancing the convenience of administration. SKB378/HBM9378 has already completed a Phase I clinical trial in China for moderate to severe asthma and has demonstrated good safety and preliminary efficacy. With the advancement of this collaboration, more clinical studies on COPD are planned, marking the drug as a potential new option for treating such severe respiratory diseases. According to the terms of the agreement signed by the parties, Kelun Botai and Harbour BioMed will receive up to $970 million from Windward Bio in upfront and milestone payments, along with tiered royalties based on net sales ranging from single to double digits percentage. Specifically, the upfront and near term payments total $45 million, including cash consideration and equity in Windward Bio's parent company. This partnership will operate under the NewCo model, with Windward Bio assuming responsibility for the research, development, production, and commercialization of SKB378/HBM9378 globally (excluding Greater China as well as parts of Southeast and West Asia). 4.Simcere Zaiming collaborates with AbbVie to drive breakthroughs in multiple myeloma treatment On January 13, 2025, Simcere Zaiming announced a significant development license option agreement with AbbVie. The collaboration centers around Simcere Zaiming's independently developed tri-specific antibody, SIM0500, which is currently in Phase I clinical studies in both China and the United States and has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA). As a humanized tri-specific antibody targeting multiple myeloma (MM), SIM0500 uniquely targets G Protein-Coupled Receptor Class C Group 5 Member D (GPRC5D), B-cell maturation antigen (BCMA), and the CD3 molecule on T-cell surfaces. This multi-target approach enhances the selectivity and potency against tumor cells while improving treatment safety and efficacy. Location and structure of GPRC5D4 SIM0500 features a low-affinity but highly target-specific CD3 antibody, which helps to avoid severe side effects such as cytokine release syndrome (CRS) often associated with traditional bispecific antibodies. Additionally, SIM0500 can recognize and bind to the highly expressed antigens GPRC5D and BCMA on malignant plasma cells, precisely directing the patient's immune system, especially T-cells, to attack the tumor cells. In preclinical studies, SIM0500 exhibited significant antitumor effects, good tolerability, lower effective doses, and sustained response after discontinuation, indicating its potential to be a leading candidate amongst treatments for multiple myeloma. These characteristics position SIM0500 to potentially overcome resistance issues with existing therapies, providing a novel and more effective treatment option for patients. From a commercial perspective, this partnership represents a significant milestone for Simcere Zaiming. Under the terms of the agreement, Simcere Zaiming will receive an upfront payment from AbbVie and is eligible for up to USD 1.055 billion in option and milestone payments. Additionally, Simcere Zaiming will receive tiered royalties on net sales of the product outside of the Greater China area. This not only offers direct financial returns but also the opportunity to share in the global market success of SIM0500. AbbVie, in turn, will receive tiered royalties on net sales in the Greater China area. This collaborative model not only accelerates the development of SIM0500 but also reflects the high recognition and support of multinational pharmaceutical companies for innovative Chinese pharmaceutical enterprises. 5.Bispecific Antibody ICP-B02 (CM355): InnoCare Pharma Partners with Keymed Biomedical to Forge New Frontiers in Cancer Immunotherapy On January 20, 2025, InnoCare Pharma and Keymed Biomedical jointly announced a significant collaboration involving a licensing agreement with Prolium Bioscience to develop and commercialize a bispecific antibody named ICP-B02 (CM355). ICP-B02 is an innovative therapeutic that can simultaneously recognize and bind to CD20 positive target cells and CD3 positive T cells. CD20 is an antigen predominantly found on the surface of B-cell lymphomas, while CD3 is a signature molecule on T cells, involved in the activation of these cells. This dual-targeting mechanism not only directs the immune system's T cells to the tumor cells but also activates them to enhance their ability to effectively kill cancer cells through a process known as T-cell-mediated cytotoxicity (TDCC). Summary of the known mechanisms of action of anti-CD20 monoclonal antibodies5 ICP-B02 exemplifies the modern trend in tumor immunotherapy – utilizing the body's own immune system to fight cancer through direct contact between cells. This physical proximity not only increases the immune system's ability to recognize tumor cells but also triggers a series of complex signal transduction events through crosslinking the T Cell Receptor (TCR) and CD3 complex. Initially, the CD3 molecules on the surface of T cells are activated under the multivalent cross-linking mediated by ICP-B02, leading to phosphorylation of intracellular motifs in the TCR/CD3 complex, thereby initiating downstream signaling pathways. These signals generally involve the activation of a series of kinases, including Lck and ZAP-70, which collectively enhance T-cell activity. Further, the activation of T cells induced by ICP-B02 is also accompanied by the activation of various effector functions, such as the release of cytokines and cytotoxic granules. In particular, T cells can secrete perforin and granzymes, which can penetrate the membranes of tumor cells and initiate programmed cell death. Moreover, ICP-B02 also promotes T-cell-mediated cytotoxicity (TDCC), where through direct cell-to-cell contact, T cells can effectively destroy neighboring tumor cells. Additionally, ICP-B02 has been optimized to reduce potential toxicity to normal tissues while enhancing therapeutic efficacy. Currently, ICP-B02 is undergoing Phase I/II clinical trials in China, primarily targeting patients with relapsed or refractory non-Hodgkin's lymphoma (NHL), including follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). Preliminary results have demonstrated that ICP-B02, whether administered intravenously or subcutaneously, has shown good safety and significant antitumor activity in patients with these types of lymphoma. This partnership brings significant economic value and development opportunities to InnoCare Pharma and Keymed Biomedical. According to the agreement, both companies will receive up to $520 million in total payments, including upfront payments, near-term payments, and additional payments upon reaching certain clinical development, registration, and commercialization milestones. Additionally, they will hold a minority stake in Prolium Bioscience and are entitled to receive tiered royalties on net sales of future products. Notably, Prolium has acquired the rights for development, registration, production, and commercialization in the global non-oncology domain and outside Asia in oncology. This deal not only reflects the international pharmaceutical industry's recognition of ICP-B02's potential but also signifies a solid step forward for InnoCare Pharma and Keymed Biomedical in expanding into the global market. Summary In review, examining the antibody drug collaborations in January 2025, we can see that Chinese pharmaceutical enterprises are focusing their research on highly expressed and critically important targets for both hematologic malignancies and respiratory diseases such as BCMA, CD20, CD19, and TSLP. These targets are not only significant for diagnosing diseases but are also crucial for developing precision treatment strategies. Therefore, the antibody design and clinical trials centered around these targets often achieve notable therapeutic effects, bringing new hope for cure to patients.  However, while pursuing innovation, balancing efficacy and safety remains a significant challenge for all researchers. For instance, although SIM0500 was designed to minimize the risk of side effects, continuous monitoring and evaluation are still required in its application. Considering the complexity and diversity of different indications, each novel antibody requires rigorous clinical validation to ensure its safety and efficacy, which is crucial for improving the overall quality of the medication and its competitive position in the market.
