WATERTOWN, Mass., May 03, 2022 (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 first quarter ended March 31, 2022.

“Kymera has made continued progress in the first quarter against our goals to build a fully integrated degrader medicines company,” said Nello Mainofi, PhD, Co-Founder, President and CEO. “With three active clinical programs, 2022 promises to be a year rich in data and milestones that build upon our prior scientific achievements. Of note, we anticipate sharing initial safety and proof-of-mechanism data for our two oncology programs, KT-413 and KT-333, and filing an IND for our MDM2 program, KT-253, in the second half of 2022. Additionally, we have finalized the dose selection and amended the design of the KT-474 Phase 1 patient cohort to include 28 days of dosing, which is now expected to deliver additional key de-risking data in 2H22. With a robust pre-clinical pipeline complementing our clinical stage programs, and a cash runway into 2025, we remain well-positioned to deliver at least one new clinical program per year, thus broadening the potential clinical and eventual commercial impact of our pipeline.”

Business Highlights and Recent Developments

IRAK4 Degrader Program (KT-474)

Background. KT-474 is designed as a potent, highly selective, orally bioavailable IRAK4 degrader, in development for the treatment of IL-1R/TLR-driven autoimmune and autoinflammatory diseases with high unmet medical needs. In 2021, Kymera completed dose escalation in the single ascending dose (SAD) and multiple ascending dose (MAD) portions of its KT-474 Phase 1 trial, the industry’s first randomized, placebo-controlled trial in healthy adult volunteers for a heterobifunctional degrader drug. The data demonstrated near complete IRAK4 degradation in PBMC and skin, robust inhibition of multiple ex vivo-stimulated disease-relevant cytokines, and a favorable safety profile. 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. Kymera has selected the equivalent of 100 mg, in the fed state, as the dose for the Phase 1 patient cohort (Part C), which is expected to enroll up to 20 total patients with hidradenitis suppurativa (HS) and atopic dermatitis (AD). In alignment with the U.S. Food and Drug Administration (FDA) and partner Sanofi, the Part C protocol has been amended to extend the dosing period from 14 to 28 days. In addition to pharmacokinetics (PK) and pharmacodynamics (PD) data, including key inflammatory biomarker readouts in both skin and plasma, this change will allow for the exploration of clinical endpoints in both HS and AD patients, as well as an extended safety dataset. Clinical endpoints to be evaluated include Eczema Area and Severity Index (EASI) for AD, total abscess and inflammatory nodule count for HS, as well as additional measures of symptoms and physician or investigator global assessments for both diseases. More information on the Phase 1 study can be found at www.clinicaltrials.gov, identifier NCT04772885.

Expected 2022 Milestones:

  • Present clinical data from patient cohort in HS and AD patients (2H22)

  • Deliver data package to Sanofi for decision to proceed to Phase 2 (2H22)

STAT3 Degrader Program (KT-333)

Background. A target long considered “undruggable,” STAT3 is a transcriptional regulator that has been linked to numerous cancers and other inflammatory and autoimmune diseases. Kymera is developing selective STAT3 degraders for the treatment of hematological malignancies and solid tumors, as well as autoimmune and fibrotic diseases. The Company’s STAT3 degraders have the potential to provide a transformative solution to address multiple STAT3-dependent pathologies. KT-333 is being evaluated in an ongoing Phase 1 trial in adult patients with certain relapsed/refractory liquid and solid tumors, including aggressive lymphomas.

Recent Updates. In 4Q of 2021, Kymera received IND clearance from FDA for KT-333, its first-in-class STAT3 degrader. The first clinical site was activated in 1Q22, and patient recruitment is underway. Dose escalation is expected throughout 2022, with data available later this year.

Expected 2022 Milestones:

  • Present patient data, including initial safety and proof-of-mechanism clinical data, to de-risk further development (2H22)

IRAKIMiD Degrader Program (KT-413)

Background. Kymera is developing novel heterobifunctional degraders that target degradation of both IRAK4 and IMiD substrates, Ikaros and Aiolos, with a single small molecule. KT-413 is designed to address both the IL-1R/TLR and the Type 1 IFN pathways synergistically to broaden activity against MYD88-mutant B cell malignancies. KT-413 is being evaluated in an ongoing Phase 1 trial in adult patients with relapsed/refractory B cell lymphomas, including MYD88-mutant diffuse large B cell lymphoma (DLBCL).

Recent Updates. In 4Q of 2021, Kymera received IND clearance from FDA for KT-413, its first-in-class IRAKIMiD degrader. The first clinical site was activated in 1Q22, and patient recruitment is underway. Dose escalation is expected throughout 2022, with data available later this year

Expected 2022 Milestones:

  • Present patient data, including initial safety and proof-of-mechanism clinical data, to de-risk further development (2H22)

MDM2 Degrader Program (KT-253)

Background. MDM2 is the crucial regulator of the most common tumor suppressor, p53 which remains intact (WT) in more than 50% of cancers. Kymera is developing a highly potent MDM2 degrader that, unlike small molecule inhibitors, has been shown preclinically to have the ability to suppress the MDM2 feedback loop and can rapidly induce apoptosis, even with brief exposures. KT-253 has the potential to be effective in a wide range of hematological malignancies and solid tumors with functioning (WT) p53.

Recent Updates. In 4Q of 2021, Kymera nominated KT-253, its first-in-class MDM2 degrader, as development candidate. KT-253 is currently in IND enabling activities to support an IND filing in 2H22. In April, the Company presented preclinical data highlighting the biological superiority of MDM2 degradation over inhibition at the American Association for Cancer Research (AACR) Annual Meeting in New Orleans, LA. KT-253 demonstrated extremely potent in vitro cell killing and in vivo anti-tumor activity with intermittent dosing that is superior to data reported for existing small molecule inhibitors and indicates the potential for improved efficacy, safety, and broader clinical utility.

Expected 2022 Milestones:

  • File IND for KT-253 (2H22)

  • Present new preclinical data elucidating indication expansion strategies (2H22)

Platform and Discovery Programs

Background. Kymera is leveraging the Company’s proprietary E3 Ligase Whole-Body Atlas, including the differential expression profile of known E3 ligases, to pursue targets and indications that may benefit from tissue-restricted or -selective degradation. Kymera has also expanded the Company’s platform to develop a new generation of molecular glue degraders for high value undrugged and non-ligandable targets. Multiple programs are approaching development stage in 2022 from its discovery pipeline with at least one using a tissue restricted E3 ligase.

Recent Updates. In April 2022, Kymera delivered multiple presentations at the 2nd Annual Ligase Targeting Drug Development Summit, focusing on the disclosure of a novel liganded E3 ligase now part of Kymera’s expanding E3 ligase toolbox and unveiling, for the first time, Kymera’s broad approach to selecting and validating ligandability, biology, and expression of novel E3 ligases.

New Appointments

Earlier this year, the Company announced the appointment of John Maraganore, Ph.D. to its Board of Directors. Dr. Maraganore joins Kymera’s Board after having led Alnylam Pharmaceuticals as founding CEO and Director and transformed the field of RNA therapeutics for the last nearly 20 years. Dr. John Maraganore served as the founding CEO and a Director of Alnylam from 2002 to 2021, where he built and led the company from early platform research on RNA interference through global approval and commercialization of the first four RNAi therapeutic medicines, ONPATTRO®, GIVLAARI®, OXLUMO®, and Leqvio®.

Recently, Kymera appointed Todd Cooper to lead communications and corporate affairs. Cooper joins Kymera from Sanofi, where he led internal and external communications that enhanced the global pharmaceutical company’s scientific reputation, highlighted the company’s pipeline across all media types and engaged the R&D organization globally.
