Kymera Therapeutics to Present New Data Demonstrating both Single-agent and Combination Regressions in MYD88-mutant Lymphoma Preclinical Models with IRAKIMiD Degrader KT-413 at 16th ICML Meeting

Data demonstrate KT-413’s potential as a monotherapy and in combination with rituximab or BTK inhibitors, with potent antitumor activity in multiple xenograft models of MYD88^MT DLBCL

WATERTOWN, Mass., June 09, 2021 (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 announced that an abstract featuring new preclinical data for its IRAKIMiD degrader KT-413 has been selected for oral presentation at the 16th Annual International Conference on Malignant Lymphoma virtual meeting, taking place from June 18 - 22, 2021.

“The activity of single-agent targeted therapies, such as BTK inhibitors or IMiDs alone, has been modest in relapsed and refractory DLBCL, necessitating the use of combination therapy," said Jared Gollob, MD, Chief Medical Officer at Kymera Therapeutics. “These data demonstrate the broad and potent antitumor single-agent activity of KT-413 in MYD88MT^T DLBCL, combining degradation of both IRAK4 and IMiD substrates Ikaros/Aiolos in a single molecule, along with strongly additive activity in combination with rituximab or BTK inhibitors in MYD88^MT OCI-Ly10 xenografts in vivo, suggesting the potential for therapeutically relevant drug combinations in MYD88^MT DLBCL.”

Abstract Presentation Details:

• Abstract: 013
• Title: KT-413, a novel IRAKIMiD degrader of IRAK4 and IMiD substrates, has a differentiated MOA that leads to single-agent and combination regressions in MYD88^MT lymphoma models
• Session 1: New Therapeutics
• Session Time: 11:45 a.m. – 1:15 p.m. ET on Sunday, June 20, 2021
• Presenter: Duncan Walker, Ph.D.

About Pegasus™
Pegasus™ is Kymera Therapeutics’ proprietary protein degradation platform, created by its team of experienced drug hunters to improve the effectiveness of targeted protein degradation and generate a pipeline of novel therapeutics for previously undruggable diseases. The platform consists of informatics-driven target identification, novel E3 ligases, proprietary ternary complex predictive modeling capabilities, and degradation tools.

About Kymera Therapeutics
Kymera Therapeutics (Nasdaq: KYMR) is a clinical-stage biopharmaceutical company founded with the mission to discover, develop, and commercialize transformative therapies while leading the evolution of targeted protein degradation, a transformative new approach to address previously intractable disease targets. Kymera’s Pegasus™ platform enables the discovery of novel small molecule degraders designed to harness the body’s natural protein recycling machinery to degrade disease-causing proteins, with a focus on undrugged nodes in validated pathways currently inaccessible with conventional therapeutics. Kymera’s initial programs are IRAK4, IRAKIMiD, and STAT3, each of which addresses high impact targets within the IL-1R/TLR or JAK/STAT pathways, providing the opportunity to treat a broad range of immune-inflammatory diseases, hematologic malignancies, and solid tumors. Kymera’s goal is to be a fully integrated biopharmaceutical company at the forefront of this new class of protein degrader medicines, with a pipeline of novel degrader medicines targeting disease-causing proteins that were previously intractable.

Founded in 2016, Kymera is headquartered in Watertown, Mass. Kymera has been named a “Fierce 15” biotechnology company by FierceBiotech and has been recognized by the Boston Business Journal as one of Boston’s “Best Places to Work.” For more information about our people, science, and pipeline, please visit www.kymeratx.com or follow us on Twitter or LinkedIn.
