WATERTOWN, Mass., Jan. 10, 2023 (GLOBE NEWSWIRE) -- Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing targeted protein degradation (TPD) to deliver novel small molecule protein degrader medicines, today announced its research, development and corporate goals for 2023.
“2022 was a pivotal year for Kymera, as the Phase 1 trial of our lead program, KT-474 (SAR444656), demonstrated fidelity of translation from healthy volunteers to patients, an encouraging safety profile, and clinical impact in complex inflammatory diseases such as hidradenitis suppurativa (HS) and atopic dermatitis (AD), highlighting the superior clinical potential of an IRAK4 degrader over a small molecule inhibitor and validating our platform, molecule design and target selection capabilities and strategies,” said Nello Mainolfi, PhD, Founder, President and CEO. “With our oncology pipeline advancing through dose escalation, we look forward to sharing data on the clinical activity of our STAT3 (KT-333) and IRAKIMiD (KT-413) programs in their target patient populations later this year, as well as initial proof-of-mechanism data on our MDM2 degrader (KT-253). More broadly, we have demonstrated the ability to effectively translate pharmacokinetic (PK), pharmacodynamic (PD) and safety from preclinical models into patients, as well as validation of our target selection strategy, allowing us to leverage and extend these learnings as we continue to expand our pipeline with differentiated and potentially best-in-class programs in large immunology and oncology franchises.”

Kymera’s 2023 Objectives
Kymera is a leader in the discovery and development of novel small molecule therapeutics designed to selectively degrade disease-causing proteins by harnessing the body’s natural protein degradation system. The company’s data, generated in healthy volunteers and patients with HS, AD, hematological malignancies and solid tumors, has provided industry leading, proprietary know-how in TPD and enabled Kymera to focus on applications in areas with significant patient need and large commercial opportunities, including immunology and oncology.
Key objectives include:
- Collaborate with Sanofi to Initiate KT-474 Phase 2 trials
- Publish results of KT-474 Phase 1 trial, including the HS/AD patient cohort
- Demonstrate KT-413 clinical anti-tumor activity in target patient populations
- Demonstrate KT-333 clinical anti-tumor activity in target patient populations
- Initiate KT-253 Phase 1 trial in solid and hematological tumors and demonstrate KT-253 clinical proof-of-mechanism in patients
- Deliver at least 2 new development candidates (DC)/Investigational New Drugs (IND) from the preclinical pipeline in areas of large clinical and commercial opportunity and pathways where TPD has potential to provide either the only or the best-in-class solution
- Further expand the capabilities of Kymera’s Pegasus™ platform and continue to leverage Kymera’s E3 Ligase Whole-Body Atlas of over 600 unique E3 ligases, with a focus on tissue restricted E3 ligases
- Expand novel molecular glue franchise in areas of unmet medical need, exploiting a newly identified degron motif
- Advance existing collaborations, or execute additional strategic partnerships, that support the company’s evolution into a fully integrated, global biopharmaceutical company
Program Background
IRAK4 Degrader Program (KT-474/SAR444656)
KT-474 is a potent, highly selective, orally bioavailable IRAK4 degrader, in development for the treatment of IL-1R/TLR-driven complex inflammatory diseases where there is an opportunity to significantly advance the standard of care in a broad variety of diseases. 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, with the data demonstrating near complete IRAK4 degradation in peripheral blood mononuclear cells (PBMC) and skin, robust inhibition of multiple ex vivo-stimulated disease-relevant cytokines, and was generally well tolerated.
In the recently completed patient cohort of the Phase 1 trial, KT-474 showed evidence of robust IRAK4 degradation in the blood and active skin lesions of HS and AD patients, and was generally well tolerated. Treatment with KT-474 was associated with a systemic anti-inflammatory response and meaningful improvement in skin lesions and symptoms in both HS and AD patients, with internal consistency between the effect on inflammatory biomarkers and impact on clinical endpoints. KT-474 was generally safe and well-tolerated, with no serious adverse events, no drug-related infections, and no dose interruptions or discontinuations due to adverse events. Sanofi, which is collaborating with Kymera on the development of KT-474 (SAR444656) outside of the oncology and immune-oncology fields, has notified Kymera of its commitment to advance KT-474 into Phase 2 clinical studies. Initial Phase 2 clinical trials of KT-474 will investigate its potential in HS and AD, with the first study initiating in 2023.
STAT3 degrader program (KT-333)
KT-333 is designed as a potent degrader of STAT3, a transcriptional regulator that has been linked to numerous cancers and inflammatory and autoimmune diseases. KT-333 is being developed for the treatment of STAT3-dependent hematological malignancies and solid tumors. The Phase 1 clinical trial of KT-333 is designed to evaluate the safety, tolerability, PK/PD and clinical activity of KT-333 dosed weekly in adult patients with relapsed and/or refractory lymphomas, leukemias and solid tumors.
The Phase 1a dose escalation portion of the trial is ongoing. In December 2022 Kymera announced that Dose Level (DL) 1 had been completed with a total of 4 patients enrolled. All patients were heavily pretreated with multiple prior regimens and included 3 with solid tumors and 1 with cutaneous T-cell lymphoma. Plasma PK and PD translated as expected in humans, with mean maximum STAT3 degradation in PBMC following the first 2 doses averaging
IRAKIMiD degrader program (KT-413)
KT-413 is a novel heterobifunctional degrader targeting both IRAK4 and the IMiD substrates Ikaros and Aiolos. Designed to address both the IL-1R/TLR and Type 1 IFN pathways synergistically with a single molecule, KT-413 is in development for the treatment of MYD88-mutant B cell malignancies. The Phase 1 clinical trial of KT-413 is designed to evaluate the safety, tolerability, PK/PD and clinical activity of KT-413 administered as an IV infusion once every 3 weeks to adult patients with relapsed and/or refractory B-cell non-Hodgkin's lymphomas.
The Phase 1a dose escalation portion of the trial is ongoing. In December 2022, Kymera announced that the first two dose levels had been completed. Patients were heavily pretreated with multiple prior regimens and included follicular lymphoma and DLBCL, which were both wild-type for MYD88. Plasma PK and PD translated as expected in humans with both dose levels showing dose-dependent degradation of IRAK4, Ikaros and Aiolos in PBMC, with up to 95/
MDM2 degrader program (KT-253)
The FDA has cleared the IND for KT-253, an investigational degrader that targets MDM2, the crucial regulator of the most common tumor suppressor, p53, which remains intact (Wild Type) in close to
Platform and Discovery Programs
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 2023.
