GlycoVaxyn

GlycoVaxyn AG was a Swiss-based biotechnology company that operated in the vaccine development sector, specifically targeting the prevention and treatment of severe bacterial infections. The company was established in 2004 as a spin-off from the Swiss Federal Institute of Technology in Zurich (ETHZ). Its foundation was rooted in the doctoral research of co-founder Michael Wacker, who, alongside Urs Tuor and Michael Stucky, envisioned a new method for creating glyco-conjugate vaccines. Wacker, holding a Ph.D. in microbiology from ETHZ, served as the Chief Scientific Officer, translating his academic work into the company's core technology. In 2008, Philippe Dro, an experienced entrepreneur with a track record in life science transactions, was appointed CEO to steer the company's corporate development.

The company's business model centered on leveraging its proprietary in-vivo glycoengineering and bioconjugation platform. This technology enabled the production of complex conjugate vaccines within simple E. coli bacterial cells, a process designed to be faster, more reliable, and less expensive than traditional chemical conjugation methods. GlycoVaxyn's primary clients and partners were major pharmaceutical companies. The firm's revenue generation strategy involved upfront payments, equity investments, and potential milestone payments and royalties from licensing its vaccine candidates. This was exemplified by strategic collaborations with Janssen Pharmaceuticals and, most notably, GlaxoSmithKline (GSK).

The core of GlycoVaxyn's offering was its biological conjugation platform. This technology synthesizes protein-polysaccharide complexes using recombinant DNA technology inside E. coli, which simplifies the manufacturing process for conjugate vaccines. These vaccines are crucial for preventing bacterial infections like pneumonia and meningitis. The platform's main benefit was its potential to develop vaccines for bacterial pathogens that were previously difficult to target. The company's pipeline included vaccines in development for infections such as Shigellosis, pneumonia, Pseudomonas, and Staphylococcus aureus. The journey culminated in February 2015, when GSK, which had been a minority shareholder since 2012, acquired the remaining shares of GlycoVaxyn for $190 million, bringing the total valuation to $212 million.
