Kymera Therapeutics Announces Presentations on KT-621, a First-in-Class, Oral STAT6 Degrader, at the European Respiratory Society and European Academy of Dermatology & Venereology Congresses
Rhea-AI Summary
Kymera Therapeutics (NASDAQ: KYMR) will present two posters on KT-621, its first-in-class, oral STAT6 degrader, at the 2026 European Respiratory Society (ERS) Congress in Barcelona and the European Academy of Dermatology & Venereology (EADV) Congress in Vienna. The ERS poster covers Phase 1b data in atopic dermatitis (AD) patients with comorbid asthma or allergic rhinitis, while the EADV poster focuses on pruritus and sleep outcomes. KT-621 is in parallel Phase 2b trials in AD (BROADEN2, enrollment completed; topline data expected by year-end 2026, Phase 3 planned by mid-2027) and asthma (BREADTH, topline data expected late 2027).

WATERTOWN, Mass., Sept. 01, 2026 (GLOBE NEWSWIRE) -- Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of oral small molecule degrader medicines for immunological diseases, today announced that the Company will present two posters featuring previously reported data from the BroADen Phase 1b trial evaluating KT-621, its first-in-class, oral STAT6 degrader, in patients with moderate to severe atopic dermatitis (AD). The posters will be presented at the European Respiratory Society (ERS) Congress, being held September 5-9 in Barcelona, Spain, and the European Academy of Dermatology & Venereology (EADV) Congress, being held September 30-October 3 in Vienna, Austria. The ERS poster will highlight data from patients with AD and comorbid asthma or allergic rhinitis, while the EADV poster will focus on pruritus and sleep outcomes from the BroADen study.
KT-621 is currently being evaluated in parallel Phase 2b trials in AD and asthma. Enrollment in the BROADEN2 trial in AD has been completed, with topline data expected by year-end 2026 and Phase 3 AD trials planned to initiate by mid-2027. The BREADTH trial in asthma is ongoing, with topline data expected in late 2027.

About KT-621
KT-621 is an investigational, first-in-class, once daily, oral degrader of STAT6, the specific transcription factor responsible for IL-4/IL-13 signaling and the central driver of Type 2 inflammation. KT-621 is currently in Phase 2 clinical testing in atopic dermatitis (AD) and asthma. In the Phase 1 clinical study in AD patients, KT-621 demonstrated deep STAT6 degradation in blood and skin, robust reductions in disease-relevant Type 2 inflammatory biomarkers, meaningful improvements on clinical endpoints and patient-reported outcomes in AD and comorbid asthma and allergic rhinitis, and was well tolerated with a favorable safety profile. KT-621, the first STAT6-directed drug to enter clinical evaluation, has the potential to transform treatment for more than 140 million patients around the world living with Type 2 inflammatory diseases such as AD, asthma, chronic obstructive pulmonary disease (COPD), eosinophilic esophagitis (EoE), chronic rhinosinusitis with nasal polyps (CRSwNP), chronic spontaneous urticaria (CSU), prurigo nodularis (PN), and bullous pemphigoid (BP), among others.
