Kymera Therapeutics KYMR shares surged 16.6% on Thursday after announcing enrollment completion in the global phase IIb BROADEN2 study evaluating its lead candidate, KT-621, for moderate to severe atopic dermatitis (AD) nearly six months ahead of schedule. The milestone prompted KYMR to accelerate its top-line data readout timeline to year-end 2026 from its earlier guidance of mid-2027, boosting investor optimism around the development program. AD is a chronic and debilitating skin disease.
The earlier-than-expected enrollment completion significantly shortens the clinical development timeline for KT-621 and positions Kymera to potentially begin phase III studies by mid-2027, subject to regulatory discussions. Faster patient recruitment reflects strong interest from both physicians and patients in a novel oral treatment option for AD while also highlighting KYMR’s operational execution. Investors welcomed the accelerated timeline, viewing it as a step that could bring key efficacy data, subsequent late-stage development and a potential regulatory filing forward.
Phase IIb BROADEN2 Study Evaluates KT-621 in Atopic Dermatitis
The phase IIb BROADEN2 study is a placebo-controlled, dose-ranging study evaluating the efficacy, safety and tolerability of KT-621 in approximately 200 adult and adolescent patients aged 12 to 75 years with moderate to severe AD. The investigational therapy is administered across three dose levels over a 16-week treatment period.
The primary endpoint measures the percent change from baseline in the Eczema Area and Severity Index score, a validated tool for quantifying the extent and severity of AD, at week 16. Secondary endpoints are designed to assess additional efficacy measures, safety, tolerability and quality-of-life outcomes, providing a comprehensive evaluation of KT-621's therapeutic potential in patients with moderate-to-severe AD.
Year to date, Kymera stock has rallied 49.7% compared with the industry’s 1.9% growth.

KT-621 has already generated encouraging early-stage clinical results. In the phase I study in AD patients, the candidate demonstrated deep STAT6 degradation in both blood and skin, accompanied by robust reductions in type II inflammatory biomarkers associated with the disease. KT-621 also delivered meaningful improvements across clinical efficacy measures and patient-reported outcomes in AD, as well as in comorbid asthma and allergic rhinitis. Importantly, the treatment was well-tolerated and exhibited a favorable safety profile, supporting its continued advancement into mid-stage development.
Beyond AD, KT-621 is also being evaluated in the ongoing phase IIb BREADTH study for moderate-to-severe eosinophilic asthma, with top-line data expected in late 2027. The candidate enjoys the FDA’s Fast Track designation for both moderate-to-severe AD and eosinophilic asthma in the United States, a status intended to facilitate the development and review of therapies addressing serious conditions with unmet medical needs.
KT-621 is an investigational, once-daily, first-in-class oral degrader targeting STAT6, the key transcription factor driving IL-4 and IL-13 signaling, which is involved in type II inflammation. While its lead development programs focus on AD and asthma, the mechanism has potential applications across a broad range of type II inflammatory diseases, including chronic obstructive pulmonary disease, eosinophilic esophagitis, chronic rhinosinusitis with nasal polyps, chronic spontaneous urticaria, prurigo nodularis and bullous pemphigoid, among others.
