WATERTOWN, Mass., May 04, 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 reported business highlights and financial results for the first quarter ended March 31, 2023.
“Kymera made important progress in the first quarter against our ambitious goal of building a fully integrated degrader medicines company, and 2023 promises to be a year rich in data and milestones that build upon our prior scientific achievements and further establish the potential impact of our pipeline,” said Nello Mainolfi, PhD, Founder, President and CEO. “We have recently initiated the Phase 1 study of our MDM2 degrader KT-253, our fourth clinical program, where we believe targeted protein degradation has the potential to overcome the limitations of small molecule inhibitors, and we plan to investigate the potential of KT-253 for patients with liquid and solid tumors. With a growing pipeline, including the first-in-class IRAK4 degrader KT-474 currently in development with our partner Sanofi in hidradenitis suppurativa and atopic dermatitis, a robust discovery engine focused heavily on immunology, and a cash runway into the second half of 2025, we are well positioned to continue to deliver first in class therapies for patients around the world.”
Business Highlights and Recent Developments
- In January, at the J.P. Morgan Healthcare Conference, Kymera shared its key research, development and corporate goals for 2023 and newly highlighted multiple programs, heavily focused on immunology, that Kymera is advancing toward clinical development.
- In February, Kymera presented an overview of its innovative platform capabilities at the Society for Laboratory Automation and Screening Annual International Conference & Exhibition, including quantitative proteomics techniques and highly optimized fragment libraries, which enable the Company’s proprietary drug discovery engine to design and develop best-in-class precision degrader medicines for undrugged and inadequately drugged targets.
- In March, Kymera initiated a Phase 1 clinical trial evaluating Kymera’s investigational MDM2 degrader KT-253.The Phase 1 study will evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics and clinical activity of KT-253 in patients with relapsed or refractory high grade myeloid malignancies, including acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), lymphoma and solid tumors.
Anticipated Upcoming Milestones
- Kymera will deliver an oral presentation of the previously disclosed clinical data from the KT-474 Phase 1 trial at the European Academy of Dermatology and Venereology (EADV) Symposium in Seville on May 18 at 11:45 AM CEST, sharing these data for the first time at a scientific meeting.
- Kymera will present preclinical data highlighting KT-253’s pharmacological profile at the European Hematology Association (EHA) Congress in June and plans to share initial safety and proof-of-mechanism data from the Phase 1 clinical trial later in 2023.
- The Company will provide clinical trial updates focused on PK/PD and safety on its KT-333 and KT-413 programs at the International Conference on Malignant Lymphoma (ICML) in June. Kymera, as previously announced, intends to present data evaluating anti-tumor activity in the target patient populations for KT-333 and KT-413 later this year.
- Kymera’s partner Sanofi plans to initiate Phase 2 clinical studies of the IRAK4 degrader KT-474 (SAR444656) in hidradenitis suppurativa (HS) and atopic dermatitis (AD), with the first study in HS planned for initiation in 2023.
Program Background Information
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 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, will initiate Phase 2 clinical trials of KT-474, with the first study in HS planned for initiation 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 as well as to 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. In December 2022, Kymera shared 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
The Phase 1a dose escalation stage is ongoing, recruiting broadly across solid and liquid tumors. Kymera will present a clinical update focused on PK/PD and safety at the ICML meeting in June and, as previously announced, intends to present data evaluating anti-tumor activity in the target patient population later this year.
More information on the Phase 1 study can be found at www.clinicaltrials.gov, identifier NCT05225584.
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. 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/
The Phase 1a dose escalation portion of the trial is ongoing, recruiting a broad population of B cell lymphoma patients. Kymera will provide a clinical update focused on PK/PD and safety at the ICML meeting in June and, as previously announced, intends to present data evaluating anti-tumor activity in the target patient population later this year.
More information on the Phase 1 study can be found at www.clinicaltrials.gov, identifier NCT05233033.
MDM2 Degrader Program (KT-253)
KT-253 targets MDM2, the crucial regulator of the most common tumor suppressor, p53. p53 remains intact (wild type) in close to
The Phase 1 study initiated in March will evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics, and clinical activity of KT-253 in patients with relapsed or refractory high grade myeloid malignancies, including acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), lymphoma and solid tumors. Patients in the KT-253 Phase 1a dose escalation study will receive IV doses of KT-253 administered once every 3 weeks. The open-label study is intended to identify the recommended Phase 2 dose for KT-253, and is comprised of two arms, with ascending doses of KT-253 in each arm. The first arm will consist of patients with lymphomas and advanced solid tumors and the second arm will consist of patients with high grade myeloid malignancies and ALL.
More information on the Phase 1 study can be found at www.clinicaltrials.gov, identifier NCT05775406.
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, exploiting a newly identified degron motif. Multiple programs are approaching development stage in 2023.
