核心洞察
Windward Bio (搜索) launched with $200 million in Series A funding to advance WIN378, a long-acting anti-TSLP (搜索) monoclonal antibody, into Phase 2 trials for severe asthma (搜索).
WIN378, licensed from Kelun-Biotech (搜索) and Harbour BioMed (搜索), offers potential for six-month dosing, reducing treatment burden for approximately 5 million patients with uncontrolled asthma (搜索) and COPD (搜索).
The company is also developing a pipeline of long-acting bispecifics targeting validated immunological targets, with Series A funding supporting IND-enabling studies for two undisclosed programs.
Windward Bio (搜索), a clinical-stage drug development company focused on immunological diseases, has launched with $200 million in Series A financing. The funding will primarily support the Phase 2 development of WIN378, a long-acting anti-thymic stromal lymphopoietin (TSLP (搜索)) monoclonal antibody, for the treatment of severe asthma (搜索) and chronic obstructive pulmonary disease (COPD (搜索)). The company anticipates initial clinical readouts from the Phase 2 trial in 2026.
Targeting TSLP for Immunological Diseases
WIN378, licensed from Kelun-Biotech (搜索) and Harbour BioMed (搜索), is engineered for extended half-life and subcutaneous administration, potentially allowing for dosing every six months. TSLP (搜索) is a validated cytokine involved in the development and progression of various immunological diseases, including asthma (搜索) and COPD (搜索). Inhibition of the TSLP ligand has demonstrated benefits across inflammatory phenotypes in these diseases.
According to Luca Santarelli, MD, founder, CEO, and Chairman of Windward Bio (搜索), "Targeting the TSLP (搜索) ligand is a highly validated approach in multiple immunological conditions, and WIN378 represents a significant advance in TSLP therapy by enhancing the benefits of this class with a dosing regimen of every 6 months, which can reduce the burden of treatment and improve outcomes for people living with severe asthma (搜索)."
Addressing Unmet Needs in Respiratory Care
Windward Bio (搜索) aims to address the unmet needs of approximately 5 million patients with advanced, uncontrolled asthma (搜索) and COPD (搜索) in the US, Europe, and Japan. Current treatments often require frequent administration, leading to adherence challenges and suboptimal outcomes. A long-acting anti-TSLP (搜索) antibody with a six-month dosing schedule could significantly improve patient compliance and quality of life.
Naveed Siddiqi, MD, Senior Partner at Novo Holdings (搜索), stated, "Addressing the unmet needs of patients with severe, uncontrolled asthma (搜索) and COPD (搜索), particularly through innovative therapies that reduce the burden of care for both individuals and healthcare systems, represents a meaningful advancement in respiratory care. WIN378, with its best-in-class potential to provide effective treatment through a six-month dosing regimen, could transform how these challenging conditions are managed, offering both clinical and practical benefits."
Expanding the Pipeline with Bispecifics
In addition to WIN378, Windward Bio (搜索) is developing a pipeline of long-acting bispecific antibodies targeting validated immunological targets. The Series A financing will support IND-enabling studies for two undisclosed programs. The company's strategy involves harnessing synergistic biology to achieve best-in-disease efficacy for various immunology indications.
