X-Chem and Kymera Expand Existing Partnership

X-Chem, the leading provider of innovative solutions in early-stage drug discovery, today announced the expansion of its collaboration with Kymera Therapeutics, Inc. (NASDAQ: KYMR). With the expanded agreement, X-Chem will serve as the primary provider of DNA-encoded library (DEL)-based screening services to Kymera — with X-Chem applying its world-leading DEL platform to support Kymera’s discovery of first- and best-in-class protein degraders. The expanded partnership comprises 12 targets and grants Kymera exclusive rights to compounds discovered within the collaboration.

“Having worked with multiple DEL providers, we have been impressed with the quality of X-Chem’s libraries and their scientific rigor,” said Nello Mainolfi, Ph.D., Founder, President and CEO of Kymera Therapeutics. “Kymera’s unique target selection strategy is critical to our success, and X-Chem has been a valued partner in helping us to unlock challenging disease targets that can be only or best addressed by targeted protein degradation. We look forward to extending our collaboration and working together to discover revolutionary new medicines.”

Matt Clark, CEO of X-Chem, said, “The team at Kymera has built an amazing company that is a leader in the targeted protein degradation field. We are delighted to be able to work more closely with Kymera and help them discover more compounds that positively impact patients.”
