The meeting is being held March 27-31, 2026, in Denver, CO. "We're proud to share our compelling KT-621 Phase 1b results with the dermatology community at AAD. Our goal is to advance the standard of care for patients around the world, and we believe these findings bring us an important step closer to that objective," said Jared Gollob, MD, Chief Medical Officer, Kymera Therapeutics. "People living with atopic dermatitis and other Type 2 inflammatory diseases are often forced to navigate difficult tradeoffs between efficacy, safety and convenience when choosing treatment. With our novel targeted protein degradation approach, we believe KT-621 has the potential to offer a first-in-class, once-daily oral option and open new possibilities for patients. These early data showing encouraging biological and clinical activity highlight the potential to expand treatment options and improve outcomes for those with chronic immuno-inflammatory conditions." "Despite systemic therapy advances in recent years, only a fraction of patients with moderate to severe atopic dermatitis actually go onto these treatments due to access challenges or concerns related to chronic injections or safety," said Emma Guttman-Yassky, MD, PhD, Waldman Professor of Dermatology and Immunology and Health System Chair of the Kimberly and Eric J. Waldman Department of Dermatology at the Icahn School of Medicine at Mount Sinai&#x2A;. "Targeting the Type 2 inflammatory pathway through STAT6 degradation is an exciting mechanism. The early data showing impact on both biomarkers and clinical measures support further development and the potential of this novel oral drug to benefit a larger proportion of atopic dermatitis patients." Data shared at AAD from the BroADen Phase 1b single-arm, open-label trial showed consistent impact across multiple pharmacodynamic and clinical measures evaluated in 22 patients with moderate-to-severe AD. After 28 days of once-daily oral dosing, KT-621 demonstrated deep STAT6 degradation across both the 100 and 200 mg dose groups tested, with median reductions of 94% in skin and 98% in blood. KT-621 also showed robust reductions in disease-relevant Type 2 inflammatory biomarkers in blood, including median TARC reduction of 74% in patients with baseline levels comparable to dupilumab studies, up to 73% reduction of Eotaxin-3, up to 56% reduction of IL-31, and up to 14% reduction of IgE. These biological effects translated into encouraging clinical activity with similar results across both dose groups. KT-621 demonstrated an overall mean 63% reduction in EASI, 29% EASI-75 and 19% vIGA-AD of 0 or 1, 49% reduction in BSA, and 40% reduction in peak pruritus NRS, reflecting improvements in both skin lesion severity and burden as well as itch. There was also an overall mean 9-point reduction in POEM, demonstrating a clinically meaningful improvement in patient-assessed disease severity. KT-621 was well tolerated with a favorable safety profile. Parallel KT-621 Phase 2b trials in <a href="https://www.globenewswire.com/Tracker?data=s4V4YMC8fmBQoabob0w19qfW4bPGRO9AmDc3qCAHzATBuIyMhaActYPrHcdu2OBvXSmkuuXK9NjHob5YSZdpIifKtnvHWO-ldq5nwXiaOcU3gyZRWLh8W2u4tNsSIF5Q" rel="nofollow" target="_blank">atopic dermatitis and asthma</a> are ongoing, with data expected by mid-2027 and late-2027, respectively. These studies are intended to accelerate KT-621 development for subsequent parallel Phase 3 registration studies across multiple Type 2 inflammatory diseases.
