Current report

In August 2025, we teamed with Ickey Woods and the Jovante Woods Foundation to raise awareness of acute asthma attacks.

Current report

During the third quarter of 2025, we presented data supporting the development of rademikibart at the European Respiratory Society Congress 2025. Rapid and significant improvement in lung function and asthma control was observed across a broad range of type 2 inflammatory markers with the greatest improvements observed in those with elevated baseline levels of blood eosinophil counts of ≥300 cells/μL and fractional exhaled nitric oxide levels of>25 ppb. We believe this data supports our ongoing Phase 2 acute exacerbations studies in asthma and COPD. We expect to report topline data for our ongoing Phase 2 acute exacerbation studies in the first half of 2026.

Previous report

During the second quarter of 2025, we presented clinical and preclinical data supporting the development of rademikibart at the American Thoracic Society 2025 International Conference and the European Academy of Allergy and Clinical Immunology 2025 Annual Congress. In this data, rademikibart was observed to significantly improve airway function, as measured by forced expiratory volume in one second, within a day and significantly reduce acute exacerbations in patients with inflammation-mediated chronic asthma, which we believe strongly supports ongoing Phase 2 acute exacerbation studies in asthma and COPD. We expect to report topline data for our ongoing Phase 2 acute exacerbation studies in the first half of 2026. In addition, we believe that the preclinical data presented demonstrates rademikibart’s differentiated structural and molecular dynamics, including potentially enhanced IL-4Rα inhibition compared to dupilumab. These findings provide a molecular basis for the distinct efficacy and safety data observed with rademikibart.

Previous report

In July 2025, we announced that the Company’s collaborator and exclusive licensee in China, Simcere, had submitted its New Drug Application for rademikibart to the National Medical Products Administration of China for the treatment of AD in adults and adolescents. As part of our License Agreement, Connect is eligible to receive remaining milestone payments up to an aggregate amount of approximately $110 million upon the achievement of certain development, regulatory and commercial milestones. We are also eligible to receive royalties at tiered percentage rates up to low double-digit percentages on net sales in Greater China. The AD market in China represents considerable opportunity, with an estimated 70 million patients with AD.

Previous report

Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, monetization transactions, government contracts or other strategic transactions.

If we raise additional funds through collaboration agreements, strategic alliances, licensing arrangements, monetization transactions, or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.

Any debt or equity financing that we raise may contain terms that are not favorable to us or our shareholders.
