The researchers at Göttingen University’s Institute for Organic and Biomolecular Chemistry, led by Professor Lutz Tietze, succeeded in developing leading prodrug technologies by further modifying the natural product Duocarmycin and combining it with protective sugar molecules. This means that the prodrugs formed are around a million times less toxic than the drug itself and the potent form is only activated in the cancer cell by an intrinsic enzyme. "This newly developed drug is one of the most toxic artificially produced compounds," explains Tietze. "It competes with the strongest toxins found in nature, but can be converted into a virtually non-toxic product simply by adding a sugar molecule." Dr David Simpson, CEO of Iksuda Therapeutics, adds: "Iksuda is delighted to license this novel, potent and selective prodrug payload class, which we believe represents a powerful addition to the ADC field, enabling the development of a new generation of ADCs with enhanced therapeutic index."
The exclusive licence agreement between the University of Göttingen and Iksuda Therapeutics was negotiated by MBM ScienceBridge, a technology transfer organisation owned fully by the University of Göttingen Public Law Foundation. The licence includes an upfront payment and revenue-based royalties as well as significant clinical development and sales milestone payments. According to Dr Jens-Peter Horst, CEO of MBM ScienceBridge, this agreement is exemplary for the successful transfer of many years of academic research and development work into a very promising and innovative cancer therapy.

Iksuda Therapeutics is a biotechnology company focused on the development of next generation Antibody Drug Conjugates (ADCs) designed to combat difficult-to-treat tumours, including those that are resistant or refractory to current treatment regimens. Iksuda’s pipeline of stable and superior ADCs is centred on its highly stable PermaLink® conjugation platform in combination with a portfolio of highly potent cytotoxic payloads designed to enhance antitumor activity and improve the lives of cancer patients.
The Georg-August-Universität Göttingen was founded in 1737. As an internationally renowned research university it offers excellent facilities for teaching and research, worldwide networks, as well as a great research tradition - as well as a comprehensive range of more than 130 course subjects. Since 2003, the body legally responsible for the University has been a Public Law Foundation.
MBM ScienceBridge GmbH is a technology transfer organisation owned fully by the University of Göttingen and acts on behalf of nine research institutions in Lower Saxony as a technology transfer interface to companies around the world. The IP portfolio managed by MBM ScienceBridge covers innovation in the areas of Life Sciences, Chemistry, Physics, Agriculture, Forestry and Medical Technologies.
