WATERTOWN, Mass., Nov. 10, 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 third quarter ended September 30, 2021.

The company recently reported at the Targeted Protein Degradation (TPD) Summit on October 27th the single ascending dose (SAD) data following completion of dose escalation from the healthy volunteer study of Kymera’s first-in-class, oral IRAK4 degrader, KT-474. The study demonstrated up to 96% degradation of IRAK4 in vivo in peripheral blood mononuclear cells (PBMC) and up to 97% inhibition of multiple disease relevant proinflammatory cytokines. The compound continues to demonstrate a favorable safety profile.

Additionally, the company today announced clearance of its Investigational New Drug (IND) application from the U.S. Food and Drug Administration (FDA) for its first-in-class STAT3 degrader, KT-333, now poised to enter the clinic in patients with liquid and solid tumors before year end.

Kymera announced that the company will be hosting a virtual R&D Day on December 16, 2021. This R&D Day will provide new, key data from the healthy volunteer Multiple Ascending Dose (MAD) portion of the KT-474 Phase 1 trial as well as updates on Kymera’s IRAKIMiD (KT-413) and STAT3 (KT-333) programs. The company will also showcase platform expansions, emerging pipeline programs in development as well as Kymera’s vision, goals and plans for the next 5 years.

“We continue to execute and meet important milestones across our pipeline, including our recent data read-out demonstrating proof-of-mechanism and proof-of-biology in humans through the Single Ascending Dose (SAD) portion of our healthy volunteer Phase 1 study for our lead degrader program, KT-474. We believe these data underscore the potential for this drug to be a best-in-class anti-inflammatory agent as well as further validate our targeted protein degradation platform. We look forward to initiating our KT-333 Phase 1 study in patients with liquid and solid tumors now that the FDA has cleared our IND,” said Nello Mainolfi, PhD, Co-Founder, President and CEO of Kymera Therapeutics. “It is important to highlight that our STAT3 degrader, KT-333, is the first heterobifunctional degrader against an undrugged transcription factor to enter the clinic, another key “first” from the Kymera team this year. This milestone is on the heels of KT-474, which is in the midst of the first placebo-controlled, healthy volunteers Phase 1 study for a targeted protein degrader. We are also very excited to advance our KT-413 IRAKIMiD program towards the clinic and host our first R&D Day event in December, which will showcase the progress we have made and the vision, goals and plans to continue to build Kymera into a fully integrated, best-in-class global targeted protein degradation company.”

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, orally bioavailable IRAK4 degrader, is being developed for the treatment of TLR/IL-1R-driven immune-inflammatory diseases with high unmet medical need, such as atopic dermatitis, hidradenitis suppurativa, rheumatoid arthritis, and other autoimmune inflammatory indications. 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. Kymera is collaborating with Sanofi on the development of degrader candidates targeting IRAK4, including KT-474 (SAR444656), outside of the oncology and immuno-oncology fields.

Recent Updates:

  • In October 2021, Kymera presented new safety, pharmacokinetic (PK) and pharmacodynamic (PD) data, from the Single Ascending Dose (SAD) portion of the KT-474 Phase 1 randomized, placebo-controlled healthy volunteer trial, at the 4th Annual Targeted Protein Degradation Summit. The data demonstrated robust, dose-dependent IRAK4 reduction, maintained for up to 6 days, in peripheral blood mononuclear cells (PBMC) measured by mass spectrometry, resulting in mean IRAK4 reduction from baseline of 93-96% achieved at 48 hours post-dose at the top three dose levels, achieving strong proof-of-mechanism. For the first time, proof-of-biology was also established, with inhibition of ex vivo R848- or LPS-mediated induction of multiple disease-relevant pro-inflammatory cytokines and chemokines in whole blood at doses and exposures associated with mean IRAK4 reduction in PBMC of ≥85% at 24-48 hours post-dose. In Cohort 7, mean maximum cytokine inhibition as great as 97% was observed. KT-474 was also well-tolerated.
  • In July 2021, Kymera initiated dosing of healthy volunteers in the multiple-ascending-dose, or MAD, portion of the Phase 1 trial of KT-474. The MAD portion of the trial is designed to evaluate repeat daily dosing of KT-474 for 14 days, beginning with a dose of 25 mg, in healthy volunteers randomized 9:3 to KT-474 or placebo.

Expected Milestones:

  • Presentation of data from the MAD portion of the Phase 1 trial in healthy volunteers (R&D Day, 12/16/21)
  • Initiation of the Phase 1 patient cohort, including patients with hidradenitis suppurativa and atopic dermatitis (1Q22)
  • Presentation of Phase 1 data in AD and HS patient cohort (mid-2022)

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-NFkB and IRF4-Type 1 interferon pathways to enhance and broaden anti-tumor activity in multiple contexts, such as MYD88-mutant diffuse large B-cell lymphoma (DLBCL). KT-413 is being developed initially for the treatment of relapsed/refractory MYD88-mutant DLBCL, with the potential to expand into other MYD88-mutant indications and IL-1R/NFkB-driven malignancies.

Expected Milestones:

  • Clearance of KT-413 IND application to allow for subsequent initiation of Phase 1 clinical trial in relapsed/refractory B cell lymphomas, including MYD88-mutant DLBCL (4Q21)
  • Presentation of additional KT-413 preclinical data and indication expansion strategies (4Q21 and 1H22)
  • Establish Phase 1 proof-of-mechanism 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 STAT3 degraders have demonstrated strong and durable anti-tumor effects in mouse xenograft and syngeneic models of liquid and solid tumors.

Recent Updates:

  • Today, Kymera announced that it received FDA clearance of its IND to evaluate its lead STAT3 degrader candidate, KT-333, in a Phase 1 clinical trial in relapsed/refractory liquid and solid tumors. Kymera expects to commence a Phase 1 clinical trial before year end. KT-333 is the first heterobifunctional degrader against an undrugged transcription factor to enter clinical development.
  • In November 2021, Kymera announced that multiple abstracts were accepted from its STAT3 degrader program at the upcoming Society for Immunotherapy of Cancer’s (SITC) 36th Annual Meeting and 63rd American Society of Hematology (ASH) Annual Meeting. At SITC, Kymera will present new preclinical data demonstrating the therapeutic potential of its STAT3 degraders for the treatment of solid tumors. In an in vivo mouse model of colorectal cancer (CT-26) that is poorly responsive to anti-PD1 monotherapy, a STAT3 degrader was evaluated in combination with anti-PD1 therapy, demonstrating robust anti-tumor synergy and development of immunological memory. At ASH, Kymera will present new preclinical data demonstrating STAT3 degrader KT-333’s potential to be administered intermittently to drive tumor regressions, including in in vivo models of peripheral T-cell lymphomas (PTCL), such as anaplastic large cell lymphoma (ALCL).

Expected Milestones:

  • Initiation of Phase 1 clinical trial of KT-333 in relapsed/refractory liquid and solid tumors (4Q21)
  • Establish Phase 1 proof-of-mechanism 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 -restricted degrader medicines with the goal of drugging an entirely new set of protein targets.

Corporate Update

In November 2021, the Company appointed Melissa Brody as Vice President, Business Development. Ms. Brody joins Kymera with multiple years of experience in the biotechnology industry advising biopharma companies on strategic transactions including M&A, licensing, and collaborations.

Upcoming Events
Kymera plans to host its inaugural R&D Day webinar on Thursday, December 16, 2021, to discuss its lead programs, unveil its new pathway/programs approaching clinical development, provide an expanded view of platform capabilities, as well as outline the Company’s vision and goals for the next five years.
