WATERTOWN, Mass., Aug. 05, 2026 (GLOBE NEWSWIRE) -- 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.”

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 for more than 140 million patients around the world suffering from Type 2 diseases such as atopic dermatitis (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 June 2026, the Company announced the completion of enrollment in the KT-621 BROADEN2 Phase 2b clinical trial in patients with moderate to severe atopic dermatitis nearly six months ahead of its original timeline. The earlier than expected completion of enrollment enabled the Company 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.
  
  
• Enrollment is ongoing in the KT-621 BREADTH Phase 2b clinical trial in patients with moderate to severe eosinophilic asthma. The Company expects to report data in late 2027.
  
  
• In June 2026 at the Japanese Dermatological Association (JDA) Annual Meeting, the Company presented results from the KT-621 Phase 1 study in healthy Japanese adults designed to support the enrollment of patients in Japan in global KT-621 studies. KT-621 demonstrated a favorable PK profile, rapid and sustained STAT6 degradation in blood, with median STAT6 degradation of =98% at both dose levels, and a favorable safety and tolerability profile. These results are consistent with those observed in non-Japanese healthy adults and atopic dermatitis patients.
  
  
• The Company presented data from the KT-621 Phase 1 clinical trials across leading dermatology and respiratory forums, including a late-breaking oral presentation at the Society for Investigative Dermatology (SID) Annual Meeting, an oral presentation at the American Thoracic Society (ATS) Respiratory Innovation Summit, and poster presentations at the Revolutionizing Atopic Dermatitis (RAD) and American Academy of Dermatology (AAD) Innovation Academy meetings.
  
  

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, that is currently in Phase 1 testing. KT-579 has the potential to be the first novel mechanism with broad utility in diseases where effective and well tolerated oral therapies are needed, such as lupus, Sjögren's, inflammatory bowel disease (IBD), rheumatoid arthritis (RA) and others.

• Enrollment is ongoing in the KT-579 Phase 1 clinical trial in healthy volunteers, with data expected in the fourth quarter of 2026. The Company plans to initiate a Phase 1b patient proof-of-concept trial in lupus soon after the completion of the healthy volunteer trial.
  
  
• The Company presented new preclinical data for KT-579 at the European Alliance of Associations for Rheumatology (EULAR) and Federation of Clinical Immunology Societies (FOCIS) Annual Meetings that demonstrated consistent disease-modifying activity across multiple preclinical lupus models. The Company also presented IBD data at Digestive Disease Week (DDW), where KT-579 demonstrated activity comparable or superior to clinically relevant comparators in a preclinical IBD model.
  
  

Partnered Programs

• In June 2026, under its existing collaboration, Sanofi initiated the first-in-human Phase 1 clinical trial evaluating KT-485 (SAR447971), an oral, potent and selective second generation IRAK4 degrader, in adult healthy volunteers and hidradenitis suppurativa patients. Under the terms of the collaboration, dosing of the first participant resulted in a $20 million milestone payment to Kymera. KT-485 has the potential to offer a novel oral approach for a variety of chronic immuno-inflammatory diseases. Per the collaboration, Sanofi is leading development, regulatory, and commercial efforts for the program.
  
  
• In April 2026, the Company announced that Gilead Sciences exercised its option to exclusively license KT-200, a first-in-class, oral CDK2 molecular glue degrader development candidate discovered and characterized by Kymera. As a result, Kymera achieved a $45 million milestone payment. KT-200 has the potential to deliver meaningful improvements in the standard of care for patients with breast cancer and other solid tumors. Gilead intends to progress the program into IND-enabling studies to support an IND filing in 2027.
  
  

Research

• Leveraging its unique target selection strategy, proven small molecule discovery capabilities, and deep development expertise, the Company continues to advance an early pipeline of novel oral programs with a goal to deliver at least one new development candidate per year.
  
  

Corporate

• In June 2026, the Company announced the appointment of Felix J. Baker, PhD, as Chairman of the Board of Directors. Dr. Baker succeeds Bruce Booth, DPhil, who has served as Chairman since co-founding Kymera in 2016 and will remain an Independent Director.
  
  
• In July 2026, the Company appointed Terence Rooney, MD, as Chief Medical Officer. Dr. Rooney is an accomplished drug development leader with extensive experience advancing immunology therapies across the full development lifecycle, from early clinical stage through commercialization and franchise expansion. Dr. Rooney will lead Kymera’s global clinical development strategy and guide the advancement of the Company’s oral immunology portfolio. He succeeds Jared Gollob, MD, who retired from his role after eight years of leadership at the Company and will remain as an advisor through the end of the year.
  
  
• The Company further strengthened its leadership team with the two important appointments further positioning Kymera to advance its clinical-stage pipeline through its next phase of development and growth. Penny Carlson joined as Senior Vice President, Development Operations, to oversee global clinical development operations. Elizabeth Laws, PhD, joined as Senior Vice President, Development Program Leader, to lead the strategy and global development of KT-621 and the STAT6 franchise.
