SOTIO Enters Licensing Agreement With Synaffix to Expand ADC Pipeline

• Synaffix to provide access to proprietary Antibody-Drug Conjugate (ADC) technologies
• SOTIO to develop up to three next generation bioconjugates
• Total potential deal value of up to $740 million, plus royalties on commercial sales for three ADC programs

AMSTERDAM, Oct. 16, 2023 /PRNewswire/ -- Synaffix B.V., a Lonza company (SIX:LONN) focused on commercializing its clinical-stage platform technology for the development of antibody-drug conjugates (ADCs) with best-in-class therapeutic index, enters licensing agreement with SOTIO Biotech (SOTIO), a clinical stage immuno-oncology company owned by PPF Group.

SOTIO will gain access to Synaffix's ADC technologies, GlycoConnecttm, HydraSpacetm and toxSYNtm linker-payloads, in an initial ADC program with the option to expand research and commercial licenses into two additional programs at a later date.

Under the terms of the agreement, Synaffix will be eligible to receive up to $740 million in payments spanning signature, target nomination and milestone payments plus additional royalties on commercial sales. SOTIO will be responsible for the research, development, and commercialization of the ADCs. Synaffix will be responsible for the manufacturing of components that are specifically related to its proprietary technologies.

Peter van de Sande, Head of Synaffix, said: "The selection of our ADC technologies by a seasoned ADC player like SOTIO is a strong recognition of the potential of these technologies to maximize the therapeutic index of ADCs. We look forward to partnering with SOTIO, and believe that with their singular focus on cancer immunotherapies and robust clinical pipeline, this partnership can deliver innovative medicines for patients in areas of high unmet medical need." 

Radek Spisek, Chief Executive Officer of SOTIO, said: "At SOTIO, we are building a broad pipeline of next-generation ADCs to address the challenges of solid tumors ? and access to Synaffix's ADC platform technologies will ensure we remain at the leading edge of this space. This collaboration combining SOTIO's deep expertise in solid tumor drug development with Synaffix's clinical-stage platform technology will drive important new innovations for the benefit of patients."

Synaffix was fully acquired by Lonza in June 2023 and represents a newly formed 'Center of Excellence' for bioconjugation. As a Lonza company, Synaffix will continue to operate under the Synaffix name and further expand its operations in Oss (NL) to cater for further innovation and growth.

About Synaffix

Synaffix B.V. is a biotechnology company that enables ADC product candidates using its clinical-stage, site-specific ADC technology platform based on GlycoConnecttm, HydraSpacetm and toxSYNtm, that together enable 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' technology provide end-to-end protection of the manufacturing technology as well as the resulting products through at least 2039. The business model of Synaffix is target-specific technology out-licensing, as exemplified through its existing deals with ADC Therapeutics, Mersana Therapeutics, Shanghai Miracogen (acquired by Lepu Biopharma), Innovent Biologics, ProfoundBio, Kyowa Kirin, Genmab, Macrogenics, Emergence Therapeutics (acquired by Eli Lilly), Amgen, Hummingbird Biosciences, Chong Kun Dang Pharma and ABL Bio.

Synaffix was fully acquired by Lonza in June 2023.

About The Synaffix ADC Platform Technology

Synaffix' proprietary ADC technology platform consists of GlycoConnecttm, HydraSpacetm and toxSYNtm technologies.  These technologies are aimed at enabling best-in-class ADCs from any antibody, with significantly enhanced efficacy and tolerability. 

GlycoConnecttm is a clinical-stage conjugation technology that exploits the native antibody glycan for site-specific and stable payload attachment and is tunable to DAR1, DAR2 or DAR4 formats. HydraSpacetm is a clinical-stage compact and highly polar spacer technology that is designed to further enhance therapeutic index, particularly with hydrophobic payloads. toxSYNtm is a linker-payload platform that spans key, validated MOAs for ADC product development. This includes potent topoisomerase 1 inhibitor (SYNtecan Etm), DNA damaging agents (SYNeamicin Dtm and SYNeamicin Gtm), ?-Microtubule (SYNtansinetm) and ?-Microtubule (SYNstatin Etm and SYNstatin Ftm) inhibitors as well as several unlaunched proprietary linker-payloads that were generated through the ongoing innovative efforts of the Synaffix R&D team.

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.
