The Portfolio

Our ambition is to develop a broad portfolio of vaccine candidates in different phases, offering our whole range of expertise throughout all stages and aspects of pharmaceutical product development, e.g. preclinical and clinical studies, quality assurance and industrial manufacturing, as well as legal and commercial.

This strategy ensures that more innovations are given the opportunity to reach the market faster for the benefit of humanity. At the same time, investors are offered risk diversification with greater future leverage.

Chlamydia Vaccine Candidate

Chlamydia is one of the most common sexually transmitted diseases (STD) and is caused by the bacterium Chlamydia trachomatis. It may not be considered as a major health issue but causes more than 130 million worldwide infections each year. Whilst infections can be treated, they are often not detected due to patients being asymptomatic. This often result in inflammation and pelvic pain and may later lead to fatal ectopic pregnancy and/or infertility for as many as half a million women.

But not only. Chlamydia infection also increases susceptibility and transmission of other sexually transmitted diseases such as HIV.

The current treatment of chlamydia infection is with antibiotics, which most often cures the infection. However, it will not repair any permanent damage caused by the disease, which would be prevented by a vaccine. Successful implementation of prophylactic vaccination would reduce the current extensive use of antibiotics and thus reduce the evolutionary pressure towards antibiotic resistance.

Notably, non-sexually transmitted strains of Chlamydia trachomatis are the world’s leading cause of preventable blindness.

Meet the inventors and learn more about the origin of our candidate in this short video.

We have successfully identified sections of the MOMP (Major Outer Membrane Protein) in the bacterium Chlamydia trachomatis – sequences that can be used to trigger an immune response. The specially designed protein chains are essential for creation of the vaccine, and are patent protected.

Initial studies have proven the active protein to be very immunogenic and well tolerated even without an adjuvant.

Preventive vaccines against Chlamydia are lacking on the market today. The WHO estimates over 130 million new cases each year and a widespread implementation of vaccination in adolescents has been proposed, similar to the existing HPV vaccination programmes.

Vaccines against chlamydia are estimated to have blockbuster potential where the global sales potential for a successful vaccine against chlamydia to be comparable with the sales of HPV vaccines, where Gardasil and Cervarix dominate. Together, these two vaccines sold for more than $4.2 billion in 2020 and are now estimated to reach $6.9 billion in 2026, according to Globe Life Sciences Ltd.

At present, however, only one preventive vaccine candidate against chlamydia is in clinical development. According to the board of Eurocine Vaccines, this provides the Company with a real opportunity to establish the Company’s Chlamydia vaccine candidate as a solution to the problem.

A successful vaccine against chlamydia is also considered to contribute to a reduced use of antibiotics – chlamydia infection is today mainly treated with antibiotics – which would decrease the pressure towards antibiotic resistance, a serious threat to global public health.

Up to now, five major pre-clinical studies have been performed in mice, resulting in positive antibody and T-cell responses.

Our current and future development involves;
– to set up an industrially scalable manufacturing process to ensure high quality supply to future studies

– to manufacture study products for the planned clinical study according to GMP

– to design a Phase I clinical trial to be started in the first half of 2023

Adjuvant Technology

– Endocine ™

Endocine™ is a safe, tolerable and effective vaccine adjuvant, based on natural lipid compounds and formulated as a liposomal dispersion. The manufacture of bulk adjuvant has been established in pilot-scale at GMP conditions.

It has been evaluated with several different vaccine antigens, both viral and bacterial and found compatible with peptides, proteins, polysaccharides, VLPs, as well as split and whole pathogens.

Endocine™ has shown excellent safety and tolerability in more than 400 human subjects after nasal administration in five clinical trials. The natural origin of the lipid compounds is a key to safety and regulatory approval.

The technology is also well tolerated in animal models, such as mouse, rat and ferret, as has been shown in numerous preclinical studies.

Vaccines against eight different pathogens have been tested intramuscularly or subcutaneously with Endocine™ with eight different vaccine candidates.

As an example, a vaccine candidate that was tested together with Eurocine Vaccines´ adjuvant Endocine™ in mice, showed that Endocine™ enhanced the antibody level 6-10 times after intramuscular injection, compared to the same vaccine without Endocine™.

Endocine™ is offered as a safe and effective intramuscular vaccine adjuvant for both human and veterinary use.

Vaccines against nine different pathogens have been tested intranasally with Endocine™. Including all antigen types, a total of twelve different vaccine candidates have been tested.

Ease of administration and the generation of mucosal immunity are attractive benefits of a nasal vaccine.

Endocine™ is offered as a safe and effective intranasal vaccine adjuvant for both human and veterinary use.
