Company to hold video conference call and webcast today at 8:30 a.m. ET

Watertown, Mass. (October 29, 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 reported financial results for the third quarter ended September 30, 2026, and provided business highlights and updates on its pipeline.

“Kymera’s recent progress reinforces the opportunity across our portfolio and our ability to help shape a new era of differentiated oral medicines in immunology,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “With KT-621 and KT-579, we are advancing complementary immunoregulatory mechanisms that target distinct drivers of disease, with significant potential to address unmet needs across the current treatment landscape. The last patient has now completed their week 16 visit in our KT-621 BROADEN2 Phase 2b atopic dermatitis trial, and we plan to report topline data by year-end 2026. We also are planning to initiate our first Phase 3 AD trial by mid-2027, and report data from our BREADTH Phase 2b asthma trial in late 2027.”

Dr. Mainolfi continued, “The positive results from the Phase 1 healthy volunteer trial of KT-579, which we reported today, demonstrate strong translation of its preclinical pharmacology into humans and highlight its potential to modulate multiple core inflammatory pathways through a single oral mechanism. These findings exceed our expectations in terms of depth of degradation, safety and pathway suppression measured by downstream cytokines and gene transcripts. The results provide an important foundation as we advance KT-579, our 7th degrader to enter the clinic, toward a study in lupus patients and explore the opportunity for targeting IRF5 in additional autoimmune diseases. Beyond these clinical programs, our research engine remains focused on unlocking novel biology and pursuing high value targets to build the next wave of oral medicines for patients who need effective, safe and convenient treatment options.”

Business Highlights, Recent Developments and Upcoming Milestones

STAT6 Degrader Program

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 development in atopic dermatitis (AD) and asthma. KT-621 has the potential to transform treatment paradigms by offering a safe, effective, oral option for the more than 140 million patients worldwide living with Type 2 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.

• In October 2026, the last patient received their final dose and completed the week 16 visit in the KT-621 BROADEN2 Phase 2b clinical trial in patients with moderate to severe AD. The Company plans to report topline data by year-end 2026. Subject to discussions with regulators, the Company expects to initiate the first Phase 3 trial in AD by mid-2027.

• Enrollment is ongoing in the KT-621 BREADTH Phase 2b clinical trial in patients with moderate to severe eosinophilic asthma, with topline data expected to be reported in late 2027.

• In September 2026, the Company presented data from the KT-621 BroADen Phase 1b clinical trial in AD across leading dermatology and respiratory forums, including posters at the European Academy of Dermatology and Venereology (EADV) and European Respiratory Society (ERS) Congresses.

IRF5 Degrader Program

KT-579 is an investigational, first-in-class, oral degrader of IRF5, a genetically validated transcription factor and master regulator of immunity. KT-579 has the potential to modulate multiple core inflammatory pathways through a single oral mechanism, offering a differentiated approach to serious autoimmune diseases where effective and well-tolerated oral therapies are needed, such as lupus, inflammatory bowel disease (IBD), Sjögre

Watertown, Mass. (August 5, 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 reported financial results for the second quarter ended June 30, 2026, and provided business highlights and updates on its pipeline.

“Kymera is delivering in a pivotal period of execution, with multiple clinical-stage programs advancing, important data catalysts ahead, and growing conviction in the potential of oral degrader medicines to transform the standard of care for chronic, debilitating immunological diseases,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “The rapid completion of enrollment in our KT-621 BROADEN2 Phase 2b trial in atopic dermatitis nearly six months ahead of our original timeline is a powerful example of the immense interest from clinicians and patients in a once-daily oral therapy and excellent execution from the Kymera team. The accelerated timeline enables us to pull forward our expected topline readout to year-end 2026, positions us for an earlier than anticipated start to Phase 3 trials next year, and ultimately allows us to move faster for patients who are waiting for new options.”

Dr. Mainolfi continued, “We see the significant gaps that remain across the immunology treatment landscape, and we are hearing directly from clinicians, advocacy groups, patients and their families about the need for effective, safe, and convenient approaches. We remain focused on executing across our differentiated portfolio to address those needs. With KT-621 advancing in both AD and asthma, KT-579 progressing toward Phase 1 data and a planned patient proof-of-concept trial in lupus, and important progress across our partnered programs and early discovery engine, we are translating that urgency into action as we work to deliver a new generation of oral medicines.”
