WATERTOWN, Mass., March 11, 2021 (GLOBE NEWSWIRE) — Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing targeted protein degradation to deliver novel small molecule protein degrader medicines, today reported business highlights and financial results for the fourth quarter and full year ended December 31, 2020.

“We continue to execute against our ambitious goal to build Kymera into a fully integrated, best-in-class degrader medicines company,” said Nello Mainolfi, PhD, Co-Founder, President and CEO, Kymera Therapeutics. “We have already achieved key milestones in 2021, a transformative year for Kymera and for the field of protein degradation, as we move our three lead degrader programs in immunology-inflammation and oncology into the clinic, expand our platform-enabled pipeline of novel degraders, and continue to grow our team and build our capabilities to deliver a new class of medicines for patients.”

Program Updates and Milestones

Kymera is discovering and developing novel small molecule therapeutics designed to selectively degrade disease-causing proteins by harnessing the body’s own natural protein degradation system, with an initial focus on immune-inflammatory diseases and oncology.

IRAK4 Degrader Program

IRAK4 is a key protein involved in inflammation mediated by the activation of toll-like receptors (TLRs) and IL-1 receptors (IL-1Rs). Aberrant activation of these pathways is the underlying cause of multiple immune-inflammatory conditions. KT-474, a potential first-in-class, highly active and selective, orally bioavailable IRAK4 degrader, is being developed for the treatment of TLR/IL-1R-driven immune-inflammatory diseases impacting millions of patients with high unmet medical need such as atopic dermatitis, hidradenitis suppurativa, and rheumatoid arthritis. KT-474 is designed to block TLR/IL-1R-mediated inflammation more broadly compared to monoclonal antibodies targeting single cytokines, and to enable pathway inhibition that is superior to IRAK4 kinase inhibitors by abolishing both the kinase and scaffolding functions of IRAK4.

Recent Updates:

  • In February 2021, Kymera initiated dosing of healthy volunteers in a first-in-human Phase 1 single and multiple ascending dose trial designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of orally administered KT-474 in adult healthy volunteers and patients with atopic dermatitis or hidradenitis suppurativa.
  • Preclinical data and interim results from a Non-Interventional study evaluating IRAK4 expression in patients with atopic dermatitis or hidradenitis suppurativa were also recently presented at the 2nd Annual North American Protein Degradation Congress in February 2021.

Expected Milestones:

  • Presentation of final Non-Interventional trial results in hidradenitis suppurativa and atopic dermatitis (2Q21)
  • Presentation of preclinical data demonstrating superiority to small molecule kinase inhibitors across a wide variety of immune-inflammatory preclinical models (2Q21)
  • Initiation of enrollment in multiple ascending dose portion of Phase 1 trial of KT-474 following FDA clearance, including healthy volunteers and a subsequent cohort of patients with atopic dermatitis or hidradenitis suppurativa (2H21)
  • Establish Phase 1 proof-of-biology in healthy volunteers (4Q21)

IRAKIMiD Degrader Program

IRAKIMiDs are novel heterobifunctional degraders designed to degrade both IRAK4 and IMiD substrates, including Ikaros and Aiolos, with a single small molecule. IRAKIMiDs synergistically target both the MYD88-NF-kB/MAP kinase and Type 1 interferon pathways with the potential to enhance and broaden anti-tumor activity. KT-413 is being developed initially for the treatment of MYD88-mutant diffuse large B-cell lymphoma (DLBCL) with potential to expand in other MYD88-mutant indications and IL-1R/TLR/NF-kB-driven malignancies. In preclinical studies, KT-413 has demonstrated a potential first-in-class profile as a targeted therapy for MYD88-mutant DLBCL, including strong single-agent antitumor activity against MYD88-mutant lymphomas in vitro and in mouse xenograft models derived from lymphoma cell lines and patient tumors, which has led to rapid, complete, and sustained tumor regressions.

Recent Updates:

  • A late-breaking abstract, titled “Mechanisms underlying synergistic activity in MYD88MT DLBCL of KT-413, a targeted degrader of IRAK4 and IMiD substrates,” was recently accepted for presentation at the American Association of Cancer Research (AACR) 2021 Annual Meeting, taking place April 10-15, 2021.

Expected Milestones:

  • Presentation of KT-413 mechanism of action at the AACR Annual Meeting (April 10-15, 2021)
  • Submission of KT-413 IND application, and if cleared, initiation of Phase 1 clinical trial in relapsed/refractory B cell lymphomas, including MYD88-mutant DLBCL (2H21)
  • Presentation of additional KT-413 preclinical data and potential indication expansion strategies (2H21)
  • Establish Phase 1 proof-of-biology and initial clinical proof-of-concept in patients (2022)

STAT3 Degrader Program

Kymera is developing selective STAT3 degraders for the treatment of hematological malignancies and solid tumors, as well as autoimmune diseases and fibrosis. STAT3 is a transcription factor activated through a variety of different cytokine and growth factor receptors via Janus kinases (JAKs), as well as through oncogenic fusion proteins and mutations in STAT3 itself. Long considered an undruggable target, STAT3 hyperactivation is prominent in numerous liquid and solid tumors, including clinically aggressive lymphomas. Kymera’s potent and selective STAT3 degraders have demonstrated strong anti-tumor effects in mouse xenograft and syngeneic models of liquid and solid tumors.

Recent Updates:

  • In February 2021, Kymera nominated KT-333 as a STAT3 development candidate for liquid and solid tumor indications and the Company has initiated IND-enabling activities. KT-333 has demonstrated high potency and selectivity in both in vitro and in vivo preclinical models, including significant and sustained anti-tumor activity in several preclinical models of liquid and solid tumors.
  • Kymera recently presented data showing that its STAT3 degraders demonstrate potent, highly selective, and sustained STAT3 degradation leading to cancer cell death in preclinical models of hematologic malignancies at the Oxford Global Targeted Protein Degradation & PROTAC Virtual Symposium.

Expected Milestones:

  • Submission of KT-333 IND application, and if cleared, initiation of Phase 1 clinical trial in relapsed/refractory liquid and solid tumors (4Q21)
  • Presentation of additional preclinical data in liquid and solid tumors (2H21)
  • Establish Phase 1 proof-of-biology and initial clinical proof-of-concept in patients (2022)

Platform and Discovery Programs

Kymera is also actively advancing a broad pipeline of preclinical programs across a wide variety of diseases, both internally and in collaboration with existing partners Vertex Pharmaceuticals and Sanofi. The internal programs continue to be focused on undrugged or inadequately drugged nodes within highly validated pathways in immune-inflammatory and oncology indications. Kymera is also developing a new generation of tissue-selective or -restrictive degrader medicines with the goal of drugging an entirely new set of protein targets.

Key Objectives:

  • Plan to host inaugural R&D Day in 2H21 to unveil next pathway/programs approaching clinical development, as well as outline the Company’s vision for the next five years
  • Continue pipeline expansion by advancing early-stage discovery programs toward IND-enabling studies
  • Further expand the capabilities of Kymera’s Pegasus™ platform to identify the optimal pairing of disease-causing protein targets with E3 ligases to generate novel degrader product candidates
  • Leverage Kymera’s E3 Ligase Whole-Body Atlas of over 600 unique E3 ligases to identify previously unliganded E3 ligases, including tissue-selective or -restrictive, to unlock new opportunities across broad therapeutic applications
