ArkBio and Partex Deepen Strategic Collaboration to Advance Novel ATR Inhibitor AK0658 Through AI-Driven Global Development
Shanghai, China – May 30, 2025 –Shanghai Ark Biopharmaceutical Co., Ltd. (“ArkBio”), a leading Chinese biopharmaceutical company, today announced an expanded strategic collaboration with Partex, a leader in AI-driven pharmaceutical innovation, to jointly develop and out-license AK0658, a preclinical-stage ATR inhibitor demonstrating best-in-class potential. This follow-up partnership builds on the successful launch of their initial collaboration focused on autotaxin inhibitor AK0707.
Under the terms of the new agreement, ArkBio will lead preclinical development and early clinical strategy for AK0658, while Partex will deploy its proprietary Asset42 AI platform to unlock the full life cycle management potential of AK0658 across a range of new indications as well as lead the identification of strategic partners and drive global out-licensing efforts.
AK0658 is an advanced preclinical-stage ATR inhibitor with improved selectivity, enhanced pharmacokinetic (PK) properties, and superior in-vivo efficacy compared to Berzosertib, one of the most prominent ATR inhibitors in development. The compound represents a promising therapeutic candidate for multiple cancer indications where DNA damage response (DDR) pathways are implicated.
"AK0658 represents a highly promising candidate with the potential to leverage synthetic lethality approaches in cancers with DDR deficiencies," said Dr. Haiqing Yuan, Chief Operating Officer at ArkBio. "Partex has proven to be an outstanding partner in harnessing the power of artificial intelligence to unlock new opportunities for our pipeline. We are confident that this expanded collaboration will accelerate the global reach of AK0658 and bring transformative therapies to patients in need."
"Building on the momentum from our AK0707 partnership, we are excited to take this next step with ArkBio," said Dr. Frank Grams, Chief Commercial Officer at Partex. "AK0658 is a compelling candidate with strong early data, and we believe our AI-driven approach will significantly accelerate the discovery of optimal indications and ideal partners for this asset."
This ongoing collaboration highlights both companies' commitment to utilizing cutting-edge AI technology to accelerate global development and commercialization of innovative therapies.
