WATERTOWN, Mass., Feb. 22, 2024 (GLOBE NEWSWIRE) -- Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of small molecule medicines using targeted protein degradation (TPD), today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided business highlights and updates on its pipeline of protein degraders.

“In 2023, we made significant progress with our industry-leading degrader portfolio, reinforcing the potential of targeted protein degradation to have a meaningful impact on patient’s lives. Our ability to deliver reproducible and differentiated innovation has been demonstrated across multiple programs and disease areas including KT-474, KT-333 and KT-253, all advancing in clinical testing. Furthermore, with the expansion of our first-in-class immunology pipeline with our STAT6 and TYK2 programs, we have the potential to revolutionize the treatment of many immuno-inflammatory diseases using oral degrader medicines with the potential for biologics-like activity,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics.

Dr. Mainolfi continued, “Looking ahead, we’re excited to further demonstrate the advantages that our technology and platform have shown over traditional medicines and the utility of this unique mechanism across different disease contexts. We are well capitalized to execute on our strategy and invest in our best-in-industry pipeline and are energized by the opportunity to deliver on our vision and, most importantly, improve patients’ lives.”

Business Highlights, Recent Developments and Upcoming Milestones

KT-474/SAR444656 IRAK4 Degrader

• Sanofi initiated two randomized, placebo-controlled Phase 2 trials evaluating KT-474 for the treatment of hidradenitis suppurativa (HS) and atopic dermatitis (AD), and the first patients were dosed in both trials in the fourth quarter of 2023. Under the terms of the Sanofi/Kymera collaboration, the dosing of the first patients generated milestone payments totaling $55 million. Enrollment in both trials is ongoing, with topline data expected to be reported in the first half of 2025.
  

• In November, Kymera published the KT-474 Phase 1 trial results in Nature Medicine, showing robust target knockdown and pathway inhibition in healthy volunteers and reduction of disease-relevant inflammatory biomarkers in the blood and skin of HS and AD patients associated with improvement in skin lesions and symptoms.
  

KT-621 STAT6 Degrader

• Kymera unveiled its first-in-class oral STAT6 degrader, KT-621, at its Immunology R&D Day in January. STAT6 is a transcription factor specific for the IL-4/IL-13 signaling pathway that drives Type 2 inflammation in allergic diseases. In Kymera’s preclinical testing, KT-621 selectively and potently degraded STAT6 and fully blocked the IL-4/IL-13 pathway with preclinical activity in human cells and animal models equal or superior to the monoclonal antibody targeting IL-4Rα, dupilumab, thereby demonstrating broad potential across a number of dermatologic, respiratory and gastrointestinal allergic diseases.
  
• The Company plans to share additional preclinical data at upcoming medical meetings, expects to initiate a Phase 1 clinical trial in the second half of 2024 and report the Phase 1 results in 2025.
  

KT-294 TYK2 Degrader

• Kymera unveiled its first-in-class oral TYK2 degrader, KT-294, at its Immunology R&D Day in January. TYK2 is a member of the Janus Kinase (JAK) family required for Type I interferon, IL-12 and IL-23 signaling with both genetic and clinical validation in autoimmune and inflammatory diseases. KT-294 selectively and potently degrades TYK2, phenocopying the inhibition of Type I interferon, IL-12 and IL-23 signaling seen in humans with TYK2 loss of function mutations, while sparing IL-10 signaling needed for gastrointestinal epithelial integrity and mucosal healing. This profile has the potential to circumvent the limitations of both selective and non-selective TYK2 small molecule inhibitors, providing a best-in-class opportunity in several indications including inflammatory bowel disease, lupus and psoriasis.
  
• The Company plans to share additional preclinical data at upcoming medical meetings, expects to initiate a Phase 1 clinical trial in the first half of 2025 and report the Phase 1 results in 2025.
  

KT-333 STAT3 Degrader

• At the American Society of Hematology (ASH) Annual Meeting in December, Kymera reported interim data from the KT-333 Phase 1 clinical trial through an October 18, 2023 cut-off, demonstrating early signs of antitumor activity at doses that were generally well-tolerated and associated with substantial STAT3 knockdown in blood and tumor. An interferon gamma signature predictive of sensitivity to anti-PD-1 therapy was induced in the tumor biopsy of a cutaneous T-cell lymphoma (CTCL) patient following treatment on the Phase 1 study, indicating the potential of KT-333 to synergize with PD-1 antibody therapy. The Phase 1a dose escalation portion of the clinical trial is ongoing.

• The Company expects to complete the Phase 1a study and share additional proof-of-concept data to inform the program’s next development steps in 2024. These data are expected to be presented at a medical meeting.
  

KT-253 MDM2 Degrader

• In November, the Company shared preliminary data from the KT-253 Phase 1 clinical trial, as of a data cut-off of October 20, 2023, from the first 2 dose levels of Arm A (solid tumors and lymphomas) with enrollment to dose level 3 ongoing. The data demonstrated evidence of target engagement and p53 pathway activation, as well as initial antitumor activity and a lack of the traditional hematological toxicity seen with small molecule inhibitors. Kymera is also developing a biomarker-based patient selection strategy for subsequent development beyond Phase 1a. Enrollment to Arm B in high grade myeloid malignancies, including AML, is underway.
  
• The Company expects to complete the Phase 1a study and share additional proof-of-concept data to inform the program’s next development steps at a medical meeting in 2024.
  

Corporate Updates

• In January, the Company announced the closing of its upsized underwritten equity offering. Kymera intends to use the approximately $301 million net proceeds from the offering to continue to advance its pipeline of preclinical and clinical degrader programs that are designed to address large patient populations with significant need and clear commercial opportunity, and for working capital and other general corporate purposes. With cash of approximately $745 million as of January 9, 2024, the Company is well-capitalized with an expected cash runway into the first half of 2027.
  
• Kymera is relocating its corporate headquarters in Watertown, MA, to support the growing organization and scale critical research and development capabilities to enable the expansion and progress of the Company’s innovative pipeline into areas that address large clinical and commercial opportunities.
