GB-0895 is an investigational, long-acting monoclonal antibody engineered with AI to target thymic stromal lymphopoietin (TSLP), a key driver of airway inflammation. These studies will evaluate the efficacy of GB-0895 in reducing clinically significant asthma exacerbations over 52 weeks, the primary objective for both trials. GB-0895 is an antibody optimized using AI to achieve ultra-high-affinity TSLP binding, extended half-life, and high specificity. It is being developed as a long-acting therapy designed for dosing every six months to help reduce the treatment burden for people with severe asthma. GB-0895 is also being evaluated in a Phase 1 clinical trial in chronic obstructive pulmonary disease (COPD). "Advancing GB-0895 into Phase 3 marks an important milestone for Generate and for the field," said Mike Nally, chief executive officer of Generate:Biomedicines. "It demonstrates the potential of programmable biology to design optimal molecular solutions for patients with unprecedented speed and intentionality — in this instance, showing how an antibody engineered with AI can achieve a potentially best-in-class profile and advance into Phase 3 studies within just four years." "Despite significant advances in respiratory medicine, severe asthma remains difficult to control for many people," said Laurie Lee, MD, chief medical officer for immunology & inflammation at Generate:Biomedicines. "Initiating Phase 3 studies for GB-0895 reflects both our commitment to people living with severe asthma and the strength of our platform to bring forward medicines that could reduce the burden of chronic respiratory disease." Phase 1 Results Presented at ERS 2025Dave Singh, MD, professor of clinical pharmacology and respiratory medicine at the University of Manchester and medical director at the Medicines Evaluation Unit, presented Phase 1 data for GB-0895 at the European Respiratory Society (ERS) International Congress 2025 in Amsterdam. In this study of 96 people with mild to moderate asthma, GB-0895 was generally well tolerated across a wide dose range (10 mg to 1,200 mg), demonstrated dose-proportional pharmacokinetics with an approximately 89-day half-life, and produced sustained reductions in key biomarkers consistent with blocking TSLP for at least six months. These data support the six-month dosing schedule now being evaluated in the Phase 3 SOLAIRIA program.

About SOLAIRIA The Phase 3 development program for GB-0895 includes two global clinical trials, SOLAIRIA-1 and SOLAIRIA-2, enrolling approximately 1,600 patients with severe asthma across more than 40 countries in North America, Europe, Latin America, and Asia Pacific. Each trial will evaluate GB-0895 (300 mg subcutaneous every six months) versus placebo over 52 weeks, with a primary endpoint of reduction in annualized asthma exacerbation rate and additional assessments of lung function, symptom control, and quality of life. These replicate studies share nearly identical designs but differ slightly in geographic distribution to ensure robust data across diverse populations.

About GB-0895GB-0895 was designed with Generate’s generative biology platform, which integrates proprietary machine-learning models with high-throughput experimentation. GB-0895 was engineered to block TSLP, an epithelial cell-derived cytokine that helps initiate and amplify airway inflammation in asthma. Using a generative optimization technology stack, GB-0895 was computationally designed to improve potency and half-life while retaining specificity.
