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. In the Phase 1 clinical study in healthy volunteers, KT-621 demonstrated complete STAT6 degradation in blood and skin following low daily oral doses, reductions of multiple disease relevant Type 2 biomarkers, and a safety profile undifferentiated from placebo. KT-621, the first STAT6-directed drug to enter clinical evaluation, has the potential to transform treatment paradigms for more than 130 million patients around the world, including children and adults, suffering from Type 2 diseases such as atopic dermatitis (AD), asthma, bullous pemphigoid (BP), chronic obstructive pulmonary disease (COPD), chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic esophagitis (EoE), chronic spontaneous urticaria (CSU), and prurigo nodularis (PN), among others.
The Company’s KT-621 BROADEN2 Phase 2b trial in moderate to severe AD patients is ongoing, and patient dosing has commenced. Data is expected to be reported by mid-2027. The BREADTH Phase 2b trial in asthma is planned to start in the first quarter of 2026. These studies are intended to accelerate KT-621 development and enable dose selection for subsequent parallel Phase 3 registration studies across multiple Type 2 dermatology, gastroenterology and respiratory indications.
