Biocytogen Pharmaceuticals Enters Into License Agreement With Pheon Therapeutics

Exclusive License Agreement for an Oncological Target Antibody to Develop Best-In-Class ADC

Beijing, China and London, UK, July 5, 2023 – Biocytogen Pharmaceuticals (Beijing) Co., Ltd (“Biocytogen”, HKEX: 02315), a global biotech company focusing on the discovery of novel antibody therapeutics today announces an antibody license agreement with Pheon Therapeutics (Pheon), a leading Antibody-Drug Conjugate (ADC) specialist developing next generation ADCs for a wide range of hard-to-treat cancers. Under the terms of the agreement, Pheon will develop and commercialize an antibody developed using Biocytogen’s proprietary RenMiceTM platforms. Biocytogen will receive an upfront payment and is eligible for development and commercial milestone payments, as well as single-digit royalties on net sales.

Biocytogen’s proprietary RenMiceTM platforms feature the complete replacement of human antibody variable genes in situ. The platforms together with target knock-out strategy empower the generation of fully human antibodies with low immunogenicity, great diversity, species cross-reactivity, high affinity and good developability. RenMiceTM platforms and derived antibodies have been recognized by many renowned biotech and biopharmaceutical companies.

The new agreement expands Pheon’s ADC pipeline which boasts first-in-class and best-in-class ADCs to meet significant unmet clinical needs in oncology. Pheon launched in March 2022 with a $68 million Series A financing led by a strong leadership team of specialists in targeted oncology therapies and ADCs.

Dr. Yuelei Shen, President and CEO of Biocytogen, said: “We are glad to collaborate with Pheon Therapeutics. Using RenMiceTM , we have launched Project Integrum, which aims to develop fully human therapeutic antibody molecules for 1000+ targets for the development of drugs in different modalities. The combination of our strengths in fully human antibody discovery with Pheon’s strengths in ADC technologies may accelerate the generation of differentiated novel therapeutics that can bring benefits to patients.”

Bertrand Damour, Chief Executive Officer of Pheon Therapeutics, said: “This license agreement represents a significant expansion of Pheon’s pipeline, and it enhances our ability to successfully develop the next generation of ADCs. Biocytogen is a fantastic partner with groundbreaking technology that is well suited to our needs. We look forward to working with them and helping to find powerful therapies that can address the significant unmet patient need in solid tumors across a broad range of hard-to-treat cancers.”
