Kymera to present its 2025 outlook at J.P. Morgan Annual Healthcare Conference on

Tuesday, January 14, 2025, at 9:00 a.m. PT/12:00 p.m. ET

Watertown, Mass. (January 14, 2025) – Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of oral small molecule degrader medicines with biologics-like activity for immunological diseases, today announced its corporate goals for 2025, including anticipated progress on its clinical pipeline of immunology programs.

“We expect 2025 to be another year of significant progress and accomplishments, and likely our busiest year to date. After unveiling our broader immunology strategy and new pipeline last year, we are poised to demonstrate the clinical potential of our first-in-class, wholly owned STAT6 and TYK2 oral degrader programs,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “Our vision is to leverage the power of targeted protein degradation to deliver, for the first time in industry, oral drugs with biologics-like activity that have the potential to revolutionize the treatment of many inflammatory diseases with significant unmet needs. We are rapidly progressing the development of our first-in-industry oral STAT6 degrader, KT-621, and will have Phase 1 healthy volunteer data, Phase 1b atopic dermatitis data, as well as initiate the first Phase 2b study, all in 2025.”

Dr. Mainolfi continued, “In addition to the significant progress we expect with our disclosed immunology programs, we look forward to expanding our immunology pipeline with a new program disclosure in the first half of 2025, continuing to build what we believe is the best oral immunology portfolio in industry.”

Additional details around Kymera’s pipeline, including its development plans for KT-621, will be presented today at the J.P. Morgan Healthcare Conference.

Program updates on the company’s disclosed programs and platform include:

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. Currently in Phase 1 testing, KT-621 has demonstrated dupilumab-like activity and very good safety data in preclinical models. Recruiting for the KT-621 Phase 1 heathy volunteer trial is ongoing, with multiple single ascending dose (SAD) and multiple ascending dose (MAD) cohorts completed. KT-621 has the potential to address numerous Th2 diseases including 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. Kymera intends to develop KT-621, an oral drug with potential for biologics-like efficacy, with the goal of transforming the treatment paradigm for the more than 130 million patients (children and adults) in the world suffering from Th2 diseases.

Key upcoming KT-621 milestones:

TYK2 Degrader Program

KT-295 is an investigational, first-in-class, once daily, oral degrader of TYK2, a member of the Janus kinase (JAK) family required for Type I IFN, IL-12 and IL-23 signaling. Given KT-295’s ability, observed in preclinical studies, to replicate the human genetic loss of function profile of TYK2, and to block the pathway to the level of upstream biologics (e.g., anti-IL-23), KT-295 has the potential to be the first oral therapy to deliver biologics-like activity in diseases such as IBD, psoriasis and others.

Key upcoming KT-295 milestones:

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 be superior to individual upstream cytokines blockers (e.g., anti-IL-1, anti-IL-33) as an oral drug. Initial Phase 2b clinical trials for HS and AD, in collaboration with Sanofi, are currently ongoing with potential in the future to expand beyond these two indications.

Key upcoming KT-474 milestones:

Research Platform

Leveraging its proven small molecule discovery capabilities, deep expertise, and unique target selection strategy, Kymera is building an industry leading portfolio of innovative oral immunology medicines addressing high value undrugged or poorly-drugged targets for areas of significant need.
