WATERTOWN, Mass., May 09, 2025 (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 first quarter ended March 31, 2025, and provided business highlights and updates on its pipeline.

“The Kymera team continues to advance our first-in-class pipeline on the path to revolutionizing the treatment of complex immuno-inflammatory diseases,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “We are making tremendous progress across our programs and approaching key near term inflection points. In June, we will be sharing the KT-621 healthy volunteer data for our STAT6 program, an important milestone in the development of this franchise. Additionally, we recently initiated, well ahead of schedule, patient dosing in the KT-621 BroADen Phase 1b study, with data in the fourth quarter of this year. This is another important inflection point as we rapidly progress KT-621 toward later-stage studies.”

Dr. Mainolfi continued, “Additionally, we are excited to introduce KT-579, our oral IRF5 degrader program. IRF5 is a genetically validated and historically undrugged transcription factor with broad clinical promise in areas of high unmet need, and we plan to progress the program into the clinic early next year. The unique pharmacology of IRF5 that is cell type and disease specific perfectly complements Kymera’s industry-leading portfolio of oral immunology medicines and further positions the company to transform the treatment of immunological diseases for millions of patients with best-in-class oral drugs.”

“Finally, we recently made the strategic decision not to advance our TYK2 degrader, KT-295, into clinical development. Although we completed IND-enabling activities with no adverse findings in any of our studies, we have decided to reprioritize these investments. This decision will allow us to dedicate more human and capital resources to our STAT6 franchise, one of the largest immunology opportunities in the industry that is rapidly advancing, as well as to our new IRF5 program. This strategic prioritization also extends our runway from mid-2027 into the first half of 2028, well beyond multiple important catalysts across our pipeline.”

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 Th2 inflammation. In preclinical studies, KT-621 demonstrated dupilumab-like activity in several in vitro and in vivo models and was safe and well tolerated. KT-621, the first STAT6 directed medicine to enter clinical evaluation, has the potential to transform treatment paradigms for more than 130 million patients around the world, including children and adults, suffering from Th2 diseases such as AD, asthma, chronic obstructive pulmonary disease (COPD), chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic esophagitis (EoE), chronic spontaneous urticaria (CSU), and prurigo nodularis (PN), among others.

  • The Company has completed the Phase 1 healthy volunteer trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of single- and multiple-ascending doses of KT-621 compared to placebo. In June 2025, Kymera will host a webcast to disclose the complete KT-621 Phase 1 healthy volunteer SAD/MAD data, which will include STAT6 degradation, safety and additional biomarker results.

  • In April, the Company initiated dosing in the KT-621 BroADen Phase 1b trial in moderate to severe AD patients, with data expected to be reported in the fourth quarter of 2025. The open label BroADen study will evaluate a daily dose of KT-621 for 4 weeks in approximately 20 patients. The key study objective is to show that robust STAT6 degradation in blood and skin by KT-621 has a dupilumab-like effect on reducing multiple Th2 biomarkers in the blood and on the transcriptome of active AD skin lesions at four weeks. The study will also assess effects on clinical endpoints such as Eczema Area and Severity Score (EASI) and pruritus numerical rating scale (NRS).

  • Two parallel Phase 2b studies in AD and asthma patients are planned to begin in the fourth quarter of 2025 and first quarter of 2026, respectively. The Phase 2b studies in moderate to severe AD and asthma patients are expected to accelerate KT-621 development and enable dose selection for subsequent parallel Phase 3 registration studies across multiple Th2 dermatology, gastroenterology and respiratory indications.

  • The Company plans to present additional KT-621 preclinical data at the American Thoracic Society (ATS) Annual Meeting being held May 16-21, 2025, in San Francisco, CA. Additionally, the Company will be featured in an oral showcase presentation as part of the ATS Respiratory Innovation Summit.

IRF5 Degrader Program
KT-579 is an investigational, first-in-class, oral degrader of IRF5, a genetically validated transcription factor and a master regulator of immunity. KT-579 has the potential to selectively block inflammation and restore immune regulation by inhibiting pro-inflammatory cytokines, Type I IFN, and autoantibody production while sparing normal cell function. In preclinical studies, KT-579 degraded IRF5 across multiple preclinical species and in all disease-relevant tissues. In preclinical models of lupus and rheumatoid arthritis (RA), KT-579 was equally or more efficacious than clinically active or marketed small molecule inhibitors and biologics. In preclinical safety studies, KT-579 did not show any adverse effects at concentrations up to 200-fold of the projected human efficacious levels. 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), RA and others.

  • Kymera named KT-579, an oral IRF5 degrader, as its lead development candidate and intends to advance the program into Phase 1 testing in early 2026. IND-enabling studies are ongoing.

IRAK4 Degrader Program
KT-474 (SAR444656) is an investigational, first-in-class, once daily, oral degrader of IRAK4, a key protein involved in TLR/IL-1R-driven inflammation. Given IRAK4’s ability to block IL-1 family cytokine and TLR signaling, KT-474 holds promise to deliver the combined activity of upstream biologics in an oral drug for multiple diseases such as hidradenitis suppurativa (HS), AD, RA, asthma, IBD and others.

  • In partnership with Sanofi, two Phase 2b dose-ranging clinical trials for the treatment of HS and AD are ongoing with primary completion expected in the first half of 2026 for HS and mid-2026 for AD.

  • In March, the Company published findings from the Phase 1 healthy volunteer trial of KT-474 in the Journal of Clinical and Translational Science highlighting the novel pharmacokinetic and pharmacodynamic properties of KT-474, reinforcing Kymera’s innovative strategies to drive development of oral degrader medicines for multiple immuno-inflammatory diseases.

  • In April, under the terms of the collaboration agreement with Sanofi executed in 2020, Kymera achieved a milestone related to certain preclinical activities associated with the IRAK4 program, generating a milestone payment of $20 million.

Corporate Updates

  • In April, the Company appointed Noah Goodman, MBA, as Chief Business Officer. Mr. Goodman brings a wealth of diverse experience in the life sciences industry to Kymera and will lead business development strategy and activities for the company.

  • In May, the Company made the strategic decision not to advance KT-295, its oral TYK2 degrader, into clinical development, despite completing IND-enabling studies with no adverse findings. This decision will allow Kymera to focus its team and financial resources on other pipeline programs, including KT-621 and KT-579.

Financial Results

Collaboration Revenues: Collaboration revenues were $22.1 million for the first quarter of 2025 compared to $10.3 million for the first quarter of 2024. Collaboration revenues were all attributable to the Company’s Sanofi collaboration. The recently achieved $20 million milestone was recorded in the first quarter of 2025 with the majority recognized as collaboration revenue.

Research and Development Expenses: Research and development expenses were $80.3 million for the first quarter of 2025 compared to $48.8 million for the first quarter of 2024.
