The Portfolio

A vaccine adjuvant is an agent that enhances the immune response to an antigen. Eurocine Vaccines has a proprietary adjuvant technology named Endocine™.

Endocine™ is based on endogenous lipids naturally found ubiquitously in the human body. When carefully processed, formulated and mixed with an antigen it enhances the immunological reaction against disease. The technology has been shown safe in five clinical trials and has been administered to more than 400 human subjects.
Due to its outstanding safety profile and unique formulation, Endocine™ may be reformulated together with existing vaccines or novel antigens in order to;

  • Enhance the immune response and provide immunity against antigens with low immunogenicity
  • Achieve an immunological and protective effect with a lower quantity of antigen and thus be antigen-sparing
  • Potentially confer an accelerated and/or prolonged immune response

Vaccine Applications​

The adjuvant technology Endocine™ may be applied to a variety of vaccine antigens to enable stimulation of immunity using whole or split antigens, proteins or peptides.

Bacterial vaccines represent a huge market. The biggest of all vaccine products, Prevnar, prevents pneumococcal disease. In addition to existing vaccines on the market, there is an intense activity developing new vaccines against bacterial diseases, where Endocine may add to the success.
Vaccines have prevented much suffering from one of the recurring viral diseases, influenza, for a long period of time. Emerging viral diseases as well as viral diseases hitherto without prophylactic vaccines may represent promising candidates to combine with Endocine.
In the mid to longer term, Endocine may bring value to the buoyant area of cancer vaccines by enhancing the immune responses.
Allergy vaccines has a particular need for safety. The proven safety of Endocine may in the longer term add to such vaccines that need enhancement of the efficacy, without unwanted side effects.
