WATERTOWN, Mass., Aug. 07, 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 second quarter ended June 30, 2024, and provided business highlights and updates on its pipeline of protein degraders.

“This past quarter, we’ve shared important updates across our pipeline, including announcing Sanofi’s plan to expand the KT-474 Phase 2 program in HS and AD to more rapidly progress toward pivotal trials. We continue to be excited about the potential of IRAK4 degradation to address significant unmet needs in immuno-inflammatory diseases with an oral drug, as well as by Sanofi’s expanded commitment to the program,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “Additionally, we have further de-risked the safety profile of our first-in-class STAT6 degrader, KT-621, in IND-enabling studies. Based on the molecule’s highly encouraging safety in all preclinical testing, along with the compelling preclinical efficacy, we are excited to advance the program into the Phase 1 study in the second half of this year. Looking forward, we have several key inflection points as we advance our degraders into and through clinical evaluation, and we are excited by the opportunity to drive meaningful improvements in the standard of care for patients.”

Business Highlights, Recent Developments and Upcoming Milestones

IRAK4 Degrader Program

• In July, the Company announced that following a review of interim KT-474/SAR444656 safety and efficacy data by an Independent Data Review Committee, Sanofi informed Kymera that it intends to expand the ongoing Hidradenitis Suppurativa (HS) and Atopic Dermatitis (AD) Phase 2 trials to accelerate overall timelines and inform future registrational trials. The Company plans to provide further information once available, including trial designs and updated timing for the expanded Phase 2 data readouts.
  
• In July, results from the Company’s non-interventional trial evaluating IRAK4 expression in patients with HS were published in the Journal of Investigative Dermatology. The results showed overexpression of IRAK4 protein in active HS skin lesions that correlated with upregulation of gene transcripts for multiple disease-relevant mediators of inflammation, supporting the role of IRAK4 signaling in HS. Additionally, KT-474 decreased IRAK4 protein levels and inhibited proinflammatory cytokine gene expression in monocytes ex vivo, further validating the potential of IRAK4 degradation to impact the clinical manifestations of HS, AD, and potentially other TLR/IL-1R-driven immuno-inflammatory diseases.
  

STAT6 Degrader Program

• In May, Kymera presented new preclinical data at the American Thoracic Society (ATS) Annual Meeting showing that in the intranasal house dust mite-induced asthma model in IL-4/IL-4Rα humanized mice, Kymera’s first-in-class orally administered STAT6 degrader, KT-621, demonstrated excellent in vivo efficacy comparable to an IL-4Rα saturating dose of dupilumab included in the same study. KT-621 robustly blocked TH2 inflammation including B cell activation, eosinophil recruitment, serum IgE and HDM-specific IgG1 induction, and reduced disease severity in the lung in this model. KT-621 also was well tolerated with daily dosing for 30 days.
  
• Additionally in May, KT-621 preclinical data was presented at Digestive Disease Week demonstrating reversal of IL-13 stimulatory effects on esophageal smooth muscle cells, an important cell type involved in the pathophysiology of eosinophilic esophagitis.
  
• The Company plans to share additional KT-621 preclinical data at upcoming medical meetings, including the European Academy of Dermatology and Venereology (EADV) Congress, being held September 25-28, 2024, in Amsterdam, Netherlands.
  
• The Company has completed IND-enabling studies, without any adverse safety findings in any doses of the GLP toxicology studies, and intends to initiate a Phase 1 clinical trial for KT-621 in the second half of 2024 and expects data from the Phase 1 trial to be reported in the first half of 2025.
  

TYK2 Degrader Program

• Kymera unveiled its first-in-class oral TYK2 degrader, KT-294, at its Immunology R&D Day in January 2024. The Company plans to share additional preclinical data on its TYK2 degrader program at upcoming medical meetings and intends to initiate a Phase 1 clinical trial in first half of 2025, with data from the Phase 1 trial expected to be reported later that year.
  

MDM2 Degrader Program

• In June, Kymera shared new clinical data from its ongoing KT-253 Phase 1 trial at the American Society of Clinical Oncology (ASCO) Annual Meeting. The data, presented through an April 9, 2024, cut-off, showed strong proof of mechanism as well as antitumor activity in multiple tumor types shown to be sensitive in preclinical models, including responses in one of two evaluable patients with Merkel cell carcinoma and two of two patients with post-myeloproliferative neoplasm acute myeloid leukemia (post-MPN AML) without the hematological toxicity typically seen with traditional small molecule inhibitors.
  
• Dose escalation in the KT-253 Phase 1a clinical trial is ongoing in both Arm A (solid tumors and lymphomas) and Arm B (high grade myeloid malignancies). The Company expects to complete enrollment in the second half of 2024 and subsequently to share the Phase 1a data set as well as guidance on next development steps.
  
• Kymera is developing a biomarker-based patient selection strategy for subsequent development beyond Phase 1a and plans to present data later in 2024 at a medical meeting.
  

STAT3 Degrader Program

• In April, Kymera presented new preclinical data in a late-breaking research session at the American Association for Cancer Research Annual Meeting showing the structural and molecular mechanisms underlying the anti-tumor activity of its novel STAT3 degrader, KT-333. Additionally, for the first time, Kymera disclosed VHL as the ideal E3 ligase for potent, selective, rapid, and consistent STAT3 degradation in cancer models.

• In June, Kymera shared new clinical data from its ongoing KT-333 Phase 1 trial at the European Hematology Association Annual Meeting. The data, presented through a June 3, 2024, cut-off, showed antitumor responses in hematological malignancies with high unmet need, including relapsed/refractory classic Hodgkin’s lymphoma, cutaneous T-cell lymphoma, and NK-cell lymphoma, at doses that were generally well-tolerated. Complete responses were observed in two of three heavily pretreated Hodgkin’s lymphoma patients, with both patients moving to potentially curative stem cell transplants after treatment. KT-333 demonstrated proof of mechanism with evidence of robust STAT3 degradation in blood and tumor. Induction of an IFN-γ stimulated gene signature predictive of sensitivity to anti-PD1 was seen in both peripheral blood and tumor, suggestive of favorable immunomodulatory response in the tumor microenvironment following KT-333 treatment and supporting a potential novel combination partner with anti-PD-1 drugs in solid tumors.

• The Phase 1a clinical trial is ongoing with enrollment focused on Hodgkin’s lymphoma based on encouraging clinical responses. Additionally, the Company is exploring opportunities for future expansion into solid tumors in combination with immune checkpoint inhibitors and other targeted therapies. The Company expects to complete enrollment of the Phase 1a trial and share data in the second half of 2024.
  

Corporate Updates

• In April the Company announced that Felix J. Baker, PhD, was appointed to the Company’s Board of Directors. Additionally, in June, the Company announced Joanna Horobin, MD, ChB, who served on the Board of Directors for six years, retired from her position.
  
• In May, the Company held its annual Month of Service partnering with eight organizations addressing food insecurity, homelessness, educational STEM programs, and other causes. Kymera employees volunteered more than 375 cumulative hours to give back to local communities in the greater Boston area.
