• Synaffix to provide all necessary ADC technologies, including GlycoConnect�, HydraSpace� and one of its proprietary toxSYN� linker-payloads
• Innovent to develop resulting ADC as part of its innovative biologics pipeline
• Synaffix is eligible to receive an upfront payment, milestone payments as well as royalties on potential future commercial sales

AMSTERDAM--(BUSINESS WIRE)--Synaffix B.V., a biotechnology company focused on commercializing its clinical-stage platform technology that enables antibody-drug conjugates (ADCs) with best-in-class therapeutic index, today announced the signing of a non-exclusive, target-specific license agreement with Innovent Biologics Inc., a leading biopharmaceutical company developing innovative medicines for the treatment of major diseases.

Under the terms of the agreement, Synaffix will provide all the necessary proprietary ADC technologies including GlycoConnect�, HydraSpace� and one of its toxSYN� linker-payloads, to enable Innovent to rapidly progress one of its antibodies as a best-in-class ADC candidate. The deal is the culmination of a successful initial proof-of-concept research period between the companies.

Upon signature, Innovent is granted the rights to deploy the above ADC technologies for one therapeutic molecule. Innovent will be responsible for the research, development, manufacturing and commercialization of the ADC product. Synaffix will closely support Innovent�s research activities and will be responsible for manufacturing components that are specifically related to its proprietary technologies.

Synaffix is eligible to receive an upfront payment, milestone payments related to certain development and sales performance achievements, as well as royalties on potential future commercial sales of the ADC product.

Dr. Yongjun Liu, President of Innovent said:

�We are excited to collaborate with Synaffix as Innovent is expanding its pipeline into the ADC space. Our collaboration with Synaffix adds a promising new ADC candidate to our preclinical pipeline through leveraging Synaffix�s validated, differentiated and innovative ADC technology platform and Innovent�s strong antibody capabilities. Based on Synaffix�s seamless partnering model, we could rapidly combine Synaffix�s ADC technologies with Innovent�s antibody, generate compelling research data and keep moving the project ahead swiftly.�

Peter van de Sande, CEO of Synaffix said:

�This is the fourth commercial licensing deal that illustrates the potential of the Synaffix platform to increase the competitive position of our partners within the ADC space. Innovent is an ideal partner for Synaffix due to its strategic focus on innovative medicines and strong R&D capability for high quality biologic drugs. We look forward to working closely together on this exciting development program.�

�Central to enhancing our value proposition has been the addition of multiple new proprietary linker-payloads to our ADC technology portfolio. In addition to our well-understood, clinical-stage technologies, GlycoConnect� and HydraSpace�, our proprietary toxSYN� linker-payload platform facilitates any company with an antibody to develop its own highly-competitive ADC.�

Notes to Editors

About The Synaffix ADC Platform Technology

Synaffix�s proprietary ADC technology platform consists of GlycoConnect�, HydraSpace� and toxSYN� linker-payload technologies. Both GlycoConnect� and HydraSpace� are clinical-stage technologies that enable best-in-class ADCs with significantly enhanced efficacy and tolerability.

GlycoConnect� is a conjugation technology that exploits the native antibody glycan for site-specific and stable payload attachment and is tunable to DAR1, DAR2 or DAR4 formats.

HydraSpace� is a compact and highly polar spacer technology that is designed to further enhance therapeutic index, particularly with hydrophobic payloads.

toxSYN� is a platform of multiple unique linker-payloads that span key, validated mechanisms-of-action for ADC product development.

The combination of these three technologies provides developers with a �one stop� and easy-to-use ADC technology platform, allowing any antibody developer to develop its own proprietary ADC and any ADC developer to expand its pipeline further and increase its competitive position.

In September 2020, Synaffix was recognized with first place in the �Best ADC Platform Technology� award category at the World ADC Awards ceremony following a global review of technologies, voting by industry peers and final evaluation by a panel of independent industry experts.

About Synaffix B.V.

Synaffix B.V. is a biotechnology company that enables ADC product candidates using its clinical-stage, site-specific ADC technology platform. In addition to GlycoConnect� and HydraSpace� technology, the toxSYN� linker-payload platform rounds out a fully complementary technology platform that enables any company with an antibody to develop proprietary best-in-class ADC products under a single license from Synaffix.

The Synaffix platform enables a rapid timeline to clinic due to the established supply chain of technology components. Granted patents covering Synaffix�s technology provide end-to-end protection of the manufacturing technology as well as the resulting products through at least 2035. The business model of Synaffix is target-specific technology out-licensing, as exemplified through its existing deals with ADC Therapeutics, Mersana Therapeutics and Shanghai Miracogen.

Synaffix is backed by a top tier, European, life science-focused investor syndicate that includes Aravis, BioGeneration Ventures, BOM Capital and M Ventures.
