WATERTOWN, Mass., Aug. 03, 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 second quarter ended June 30, 2023.

“Kymera has made strong progress with our three proprietary clinical programs over the last quarter, including dosing our first patient in the KT-253 Phase 1 study and sharing data that both KT-333 and KT-413 reached degradation levels that were associated with anti-tumor activity in preclinical models. We believe these findings reinforce Kymera’s ability to translate our preclinical pharmacokinetic, pharmacodynamic and safety models to patients and provide a strong foundation as we expand our pipeline with potentially best-in-class, high-value programs. We expect to share updates on these programs later this year,” said Nello Mainolfi, Founder, President and CEO, Kymera Therapeutics. “Additionally, our partner Sanofi expects to initiate the first two Phase 2 clinical trials for KT-474 in the fourth quarter, moving us forward on our mission of building a fully-integrated global medicines company.”

Business Highlights and Recent Developments

• The Company presented clinical data from the KT-474 Phase 1 trial at the European Academy of Dermatology and Venereology (EADV) Symposium, sharing these data for the first time at a scientific meeting.
  
• The Company announced the first patient was dosed in the Phase 1 clinical trial evaluating its investigational MDM2 degrader, KT-253.
  
• The U.S. Food and Drug Administration (FDA) granted orphan drug designation to KT-253 for the treatment of Acute Myeloid Leukemia (AML).
  
• At the European Hematology Association (EHA) Congress, the Company presented data demonstrating superior efficacy of MDM2 degrader KT-253 compared to small molecule inhibitors in preclinical leukemia models.

• In conjunction with the International Conference on Malignant Lymphoma (ICML), Kymera provided clinical trial updates for its KT-333 and KT-413 oncology programs focused on pharmacokinetic/pharmacodynamic (PK/PD) and safety from additional patient cohorts showing target knockdown at or near levels that were associated with efficacy in preclinical tumor models. The KT-333 clinical data was presented in a poster at ICML.
  
• At the American Society for Mass Spectrometry (ASMS) Annual Meeting, Kymera presented two posters focused on Kymera’s powerful drug discovery engine and the advanced proteomics technologies utilized to provide deep insights into degrader selectivity and mechanism-of-action in physiologically relevant cellular settings at high resolution and dimensionality.
  
• In collaboration with the Raymond Birge laboratory at the Department of Microbiology, Biochemistry and Molecular Genetics, and Center for Cell Signaling at Rutgers University, Kymera published a paper in Frontiers in Immunology (link) demonstrating degraders can be designed to selectively degrade multiple tumor-associated macrophage (TAM) receptors and modulate receptor expression in vitro and in vivo. While not currently in the active pipeline, this work demonstrates the utility of proteome editing enabled by degraders toward therapeutically relevant pathway biology in preclinical models and shows the technology could serve as a viable therapeutic strategy for targeting MERTK and other TAM receptors that are expressed across a range of liquid and solid tumors.
  
• The Company announced the appointment of Jeremy Chadwick, Ph.D., as Chief Operating Officer. Dr. Chadwick joined Kymera with extensive experience overseeing global development operations, regulatory and program management at a range of biopharmaceutical companies. As a member of the Company’s senior management team, Dr. Chadwick will develop and execute near-term and long-range strategies to maximize the impact of Kymera’s expanding pipeline.
  
• In July, Justine Koenigsberg joined Kymera as Vice President and Head of Investor Relations. Ms. Koenigsberg has more than 25 years of investor relations and corporate communications experience within the biotechnology industry. She most recently served as Senior Vice President, Corporate Communications and Investor Relations at Concert Pharmaceuticals, Inc. Prior to joining Concert, she held senior communication roles at ViaCell, Inc. and Transkaryotic Therapies, Inc. (TKT) where she developed and implemented a variety of communication strategies and managed their investor relations programs. Before TKT, she held communications positions at Vertex Pharmaceuticals, Inc. Ms. Koenigsberg is a member of the National Investors Relations Institute and served on the Board of Directors and as a Past-President of its Boston Chapter. She holds a B.S. in Business Administration from Northeastern University.
  

Anticipated Upcoming Milestones

• Kymera’s partner Sanofi plans to initiate Phase 2 clinical trials of IRAK4 degrader KT-474 (SAR444656) in both HS and AD in the fourth quarter of 2023.

• Kymera plans to share updates on its clinical-stage oncology programs later this year, including data evaluating anti-tumor activity in the target patient populations for KT-333 and KT-413 and initial safety and proof-of-mechanism data from the KT-253 Phase 1 clinical trial.

Second Quarter 2023 Financial Results

Collaboration Revenues: Collaboration revenues were $16.5 million for the second quarter of 2023 compared to $11.5 million for the second quarter of 2022. Collaboration revenues include revenue from the Company’s Sanofi and Vertex collaborations.

Research and Development Expenses: Research and development expenses were $45.8 million for the second quarter of 2023 compared to $41.3 million for the second quarter of 2022. This increase was primarily due to increased expenses related to the investment in our STAT3, IRAKIMiD, and MDM2 clinical stage programs, platform and discovery programs, as well as an increase in occupancy and related costs due to continued growth in the research and development organization. Stock based compensation expenses included in R&D were $5.7 million for the second quarter of 2023 compared to $4.8 million for the second quarter of 2022.

General and Administrative Expenses: General and administrative expenses were $14.1 million for the second quarter of 2023 compared to $11.0 million for the second quarter of 2022. The increase was primarily due to an increase in legal and professional service fees in support of the Company’s growth and an increase in personnel, facility, occupancy, and other expenses from an increase in headcount to support growth as a public company. Stock based compensation expenses included in general and administrative expenses were $5.5 million for the second quarter of 2023 compared to $4.9 million for the second quarter of 2022.

Net Loss: Net loss was $38.8 million for the second quarter of 2023 compared to a net loss of $40.3 million for the second quarter of 2022.

Cash and Cash Equivalents: As of June 30, 2023, Kymera had approximately $472 million in cash, cash equivalents, and investments. Kymera expects that its cash and cash equivalents will provide the company with an anticipated cash runway into the second half of 2025. Its existing cash is expected to take the company past the proof-of-concept Phase 2 data for KT-474, as well as early proof-of-concept data for KT-253, KT-333 and KT-413, while Kymera continues to identify opportunities to accelerate growth and expand its pipeline, technologies and clinical indications.
