On June 25, 2026, the Company announced that it has completed enrollment in the global BROADEN2 Phase 2b trial of KT-621, its first-in-class, oral STAT6 degrader, for the treatment of moderate to severe atopic dermatitis ("AD"). Enrollment was completed in advance of prior expectations, and the Company expects this development to accelerate the timing of its anticipated topline data readout to year-end 2026, representing a potential advancement of six months relative to its prior expectation of releasing the readout in mid-2027. Subject to discussions with regulators, the Company expects to initiate Phase 3 trials in AD by mid-2027.

## Exhibit 99.1

**Exhibit 99.1**![LOGO](g62555dsp_5.jpg)

**Kymera Therapeutics Completes Enrollment in the Phase 2b BROADEN2 Trial of** 

**KT-621 in Atopic Dermatitis with Topline Data by Year-end 2026** 

*BROADEN2 enrollment completed nearly six months ahead of anticipated timelines* 

*KT-621 Phase 3 trials in AD planned to initiate by mid-2027* 

*KT-621 BREADTH Phase 2b asthma trial ongoing, with data expected to be reported in late 2027* 

**Watertown, Mass. (June 25, 2026) –** 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 it has completed enrollment in the global BROADEN2 Phase 2b trial of KT-621, its first-in-class, oral STAT6 degrader, for the treatment of moderate to severe atopic dermatitis (AD). The earlier than expected completion of enrollment enables Kymera to accelerate its expected topline data readout by six months to year-end 2026, earlier than prior guidance to share data by mid-2027. Subject to discussions with regulators, the Company expects to initiate Phase 3 trials in AD by mid-2027.

"Completing enrollment in BROADEN2 nearly six months ahead of our anticipated timeline reflects a high degree of patient and provider interest in a safe and effective oral option for atopic dermatitis, a chronic and debilitating disease. It's also a testament to KT-621's compelling profile across preclinical, healthy volunteer, and patient studies, and the best-in-industry execution of our team," said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. "With enrollment now complete, we are positioned to bring forward our expected topline data readout to this year as well as accelerate our planned Phase 3 initiation, subsequent readouts, and NDA filing."

BROADEN2 is a global, randomized, double-blind, placebo-controlled, dose-ranging study evaluating the efficacy, safety, and tolerability of three doses of KT-621 in approximately 200 adult and adolescent patients, ages 12 to 75, with moderate to severe AD over 16 weeks. The primary endpoint is the percent change from baseline in Eczema Area and Severity Index (EASI) score at Week 16. Secondary endpoints will evaluate additional safety, efficacy, and quality-of-life measures. KT-621 is also being evaluated in the ongoing BREADTH Phase 2b trial in moderate to severe eosinophilic asthma, with data expected to be reported in late 2027. The Company previously announced that KT-621 has received Fast Track designation from the U.S. Food and Drug Administration for the treatment of moderate to severe AD and eosinophilic asthma.

**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.
