SOTIO will leverage Synaffix’s antibody-drug conjugate platform for the design of up to three novel ADCs to address indications with high unmet medical need Collaboration bolsters SOTIO’s wider portfolio of differentiated immuno-oncology therapies tailored to address the specific challenges of solid tumors Synaffix will receive an upfront payment and potential development milestone payments totaling $740 million PRAGUE--(BUSINESS WIRE)-- SOTIO, a clinical-stage immuno-oncology company owned by PPF Group, today announced a license and option agreement with Synaffix B.V., a Lonza company, to develop next-generation antibody-drug conjugates (ADCs) for the treatment of solid tumors. SOTIO will leverage Synaffix’s ADC technology platform to develop up to three novel ADCs targeting distinct tumor-associated antigens. “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,” said Radek Spisek, M.D., Ph.D., chief executive officer of SOTIO. “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.” The deal enables SOTIO to combine its proprietary antibodies with Synaffix’s ADC technology platform in order to deliver innovative new ADCs that can overcome the challenges of treating solid tumors. In addition to GlycoConnect™ and HydraSpace™, the deal also includes Synaffix’s potent linker-payload platform including multiple different payloads. “Synaffix’s ADC technology perfectly complements the technologies already in SOTIO’s ADC platform, including the iADC technology licensed from NBE-Therapeutics and the ConjuALL technology licensed from LegoChem,” said Martin Steegmaier, chief scientific officer of SOTIO. “The addition of Synaffix’s capabilities will greatly expand our ability to select and tailor the most suitable ADC technology and payload for the needs of a particular target and particular solid tumor indication.” Under the terms of the agreement, Synaffix is eligible to receive upfront and potential milestone payments worth up to $740 million, plus single-digit royalties on net sales. SOTIO will be responsible for research, development, manufacturing and commercialization of the ADC products, while Synaffix will closely support SOTIO’s research activities and be responsible for the manufacturing of components that are specifically related to its proprietary GlycoConnect™, HydraSpace™, and linker-payload technologies. Peter van de Sande, head of Synaffix, added, “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.” SOTIO is advancing a pipeline of novel ADCs tailored to address the treatment needs of specific solid tumor types. SOT102, the company’s most advanced ADC program, is a CLDN18.2-targeting ADC in Phase 1/2 development for the treatment of gastric, pancreatic and other cancers that have very few targeted treatment options available. The company is progressing dose-finding studies in the trial’s monotherapy arm, with SOT102 as a later-stage treatment, and recently announced the initiation of the trial’s combination therapy arm in first-line treatment of gastric and pancreatic cancer patients. SOTIO additionally has two other ADC programs in preclinical development.

GlycoConnect™ High DAR technology extension enables ADCs with increased loading, while retaining drug substance homogeneity SYN-PNU™ represents a potency-attenuated version of PNU-159,682, the latest addition to the toxSYN™ linker-payload portfolio AMSTERDAM, Oct. 12, 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, today announces that its Founder and head of R&D, prof. Floris van Delft, will present data on the launch of two new technologies during a plenary session at the World ADC conference in San Diego, at 8.15 am PDT on Wednesday 18 October 2023. GlycoConnect™ High DAR Technology GlycoConnect™ enables any antibody to be converted into a stable conjugated ADC in a non-genetic fashion, by modifying the native antibody glycan using Synaffix's efficient enzymes and metal-free click chemistry approach. The extension of GlycoConnect™ with High DAR Technology enables ADCs with high drug loading (6, 8 and above), while retaining high drug substance homogeneity and therapeutic index. SYN-PNU™ Linker-Payload Synaffix's proprietary toxSYN™ linker-payloads provide multiple options to maximize efficacy by matching the best mechanism of action with the tumor biology specific to the ADC target. The newest proprietary linker-payload, "SYN-PNU™" is part of the established and expanding toxSYN™ linker-payload portfolio. SYN-PNU™ represents (based on pre-clinical models) a significantly potency-attenuated and better tolerated version of PNU-159,682, to enable enhanced administered dose levels and competitive therapeutic properties versus ADCs prepared using the original molecule. The reference compound (PNU-159,682) is metabolite of the anthracycline Nemorubicin and represents a highly potent DNA topoisomerase II inhibitor. Prof. Floris van Delft, Founder and Chief Scientific Officer , Synaffix, said: "I look forward to presenting the underlying data supporting our new High DAR and SYN-PNU™ technologies at the World ADC conference, announcing the addition of a new and powerful Mode-of-Action (MoA) to our tox-SYN™ linker-payload toolbox and demonstrating how we can achieve higher drug loading on any antibody without departing from our 'engineering free' approach that all our clients love. We are excited by the potential of these new technologies to further enhance the ability of our licensees to discover, develop and commercialize ADCs with best-in-class therapeutic properties."
