WATERTOWN, Mass., Aug. 09, 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 second quarter ended June 30, 2022.

“Kymera has made strong progress, dosing patients in our three first-in-class clinical programs and advancing our mission to build a fully integrated medicines company,” said Nello Mainolfi, PhD, Co-Founder, President and CEO. “We are on track to deliver clinical data before year end for all three programs, including our KT-474 Phase 1 patient cohort, where we expect to demonstrate the ability of KT-474 to degrade IRAK4 and impact disease relevant biomarkers in the skin and blood of HS and AD patients. We also plan to share initial safety and proof-of-mechanism data for our two oncology programs, KT-413 and KT-333. With a cash runway into 2025, we are well-financed and poised to deliver clinical results in the second half of this year that reinforce the exciting and broad potential of our targeted protein degradation pipeline and platform.”

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 peripheral blood mononuclear cells (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 commenced dosing patients in the Phase 1 patient cohort (Part C). Part C is an open-label study of KT-474 administered daily on an outpatient basis for 28 days. This cohort is expected to enroll up to 20 patients with moderate-to-severe hidradenitis suppurativa (HS) or atopic dermatitis (AD) to examine the safety and pharmacokinetics/pharmacodynamics (PK/PD) of KT-474 and explore early signs of clinical activity of this first-in-class degrader therapeutic. Patients will receive a daily dose of 75 mg of KT-474 with food. This dose is expected to provide a plasma exposure that is approximately equivalent to that achieved with the 100 mg per day dose in the fasted state in healthy volunteers in the MAD portion of the trial, which showed maximal or close to maximal degradation in blood and skin and broad disease relevant cytokine inhibition ex vivo.

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 (4Q22)
• Deliver data package to Sanofi for decision to proceed to Phase 2 (4Q22)

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.

Recent Updates. Patient enrollment and dosing are ongoing in a Phase 1 clinical trial of KT-333 evaluating the safety, tolerability, PK/PD and clinical activity of KT-333 in adult patients with relapsed and/or refractory lymphomas and solid tumors. The first stage of the study will explore escalating doses of KT-333 in a broad variety of tumor types. The second stage is expected to consist of expansion cohorts to further characterize the safety, tolerability, PK/PD and antitumor activity of KT-333 in relapsed and/or refractory peripheral T-cell lymphoma (PTCL), cutaneous T-cell lymphoma (CTCL), large granular lymphocytic leukemia (LGL-L), and solid tumors.

KT-333 was recently granted Orphan drug designation by the U.S. Food and Drug Administration for the treatment of PTCL. This designation provides incentives to encourage the development of medicines for rare diseases.

Expected 2022 Milestones:

• Present KT-333 clinical patient data, including initial safety and proof-of-mechanism (4Q22)

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.

Recent Updates. Patient enrollment and dosing are ongoing in a Phase 1 clinical trial of KT-413 evaluating the safety, tolerability, PK/PD and antitumor activity of KT-413 in patients with relapsed and/or refractory B-cell non-Hodgkin's lymphomas. The first stage will explore escalating doses of single-agent KT-413 in a broad B-cell lymphoma population. The second stage is expected to consist of expansion cohorts to further characterize the safety, tolerability, PK/PD and antitumor activity of KT-413 in relapsed/refractory MYD88-mutant diffuse large B cell lymphoma (DLBCL).

Expected 2022 Milestones:

• Present KT-413 clinical patient data, including initial safety and proof-of-mechanism (4Q22)

MDM2 Degrader Program (KT-253)

Background and Update. 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 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. Kymera is completing IND enabling studies for KT-253 and expects to file an IND in 2H22.

Expected 2022 Milestones:

• File IND for KT-253 (2H22)
• Present preclinical translational data to inform long-term clinical strategy (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.
