Basel, Switzerland and Prague, Czech Republic – November 7, 2019 – NBE-Therapeutics AG and SOTIO today announced that SOTIO has selected a second target for the development of a next generation antibody-drug conjugate (ADC) based on their existing collaboration and license agreement. NBE and SOTIO will collaborate on the discovery, non-clinical development and manufacturing of this undisclosed second target. Development will be based on NBE’s proprietary antibody drug conjugate platform, including NBE’s SMAC-technology™ site-specific conjugation and its powerful new anthracycline toxin platforms. SOTIO will assume global responsibility for the clinical development, registration and commercialization of ADC products.

NBE-Therapeutics’ new iADC™ platform creates highly potent and safe immunostimulatory ADCs with anthracycline payload, inducing a long-lasting antitumor immunological effect. It showed unprecedented preclinical data on efficacy, as well as safety, across multiple pipeline programs. Its lead program NBE-002 against the ROR1 target has successfully passed the GLP toxicology study and is in the final stages of the CMC. It is expected to begin its first human study by mid-2020 for triple-negative breast cancer and lung cancer, as well as other cancer indications.

NBE is entitled to the option exercise fee, as well as milestone payments and royalties based on the overall net sales of the products. In addition, NBE will be reimbursed for R&D expenses incurred in connection with product development in collaboration with SOTIO.

Dr. Ulf Grawunder, CEO of NBE-Therapeutics, commented: “We are very excited that SOTIO has nominated a second ADC program under the existing collaboration agreement between SOTIO and NBE, confirming the high quality of our platform adc. We have now created a robust and scalable ADC platform that allows us to leverage iADC development in clinical trials for more programs. Collaborating with Sotio in recent years has further strengthened our technology and we are very proud to have them on board for a second iADC development program.”

« Based on the very encouraging data from our first NBE collaboration target and SO-N102 program, as well as data from NBE’s proprietary program NBE-002, we have now exercised the second target option in the collaboration, » says Dr. Radek Spisek, CEO of SOTIO. « NBE’s product platform addresses key issues of today’s antibody-drug conjugates and has the potential to provide new and superior therapeutic options for cancer patients. »
