What

Vaccine Discovery Platform
GlyProVac is a pre-clinical biotech platform developing new bacterial subunit vaccines using its patented BEMAP technology.

Problem

Antimicrobial Resistance
GlyProVac addresses the need for new bacterial vaccines to combatthe growing silent pandemic of antimicrobial treatment resistance.

Solution

Novel BEMAP Technology
Starting with E. coli-based infections like UTIs, GlyProVac’s BEMAP platform is an engine for creating novel bacterial vaccines.

About

Using proprietary technologies to combat antibiotic resistance

In GlyProVac ApS we aim to design and develop novel, efficient bacterial vaccine candidates based on our proprietary platform technology BEMAP. Using BEMAP, we have revealed that both benign as well as disease causing bacteria such as E. coli, Pseudomonas aeruginosa and Shigella. extensively modify their proteins with distinct sugar molecules, known as O-linked glycosylations. These modifications drastically influence the topology of the protein and are particularly well recognized by the human immune response.

Antibiotics resistance (AMR) is one of the biggest health challenges of the 21st century, compromising our ability to treat even simple infections. In 2050, 10 million people are expected to die yearly from untreatable microbial infections. New solutions are urgently needed, and vaccines offer a safe alternative to antibiotics.

Based on our paradigm changing discovery we believe inclusion of these modifications are crucial for the development of efficient bacterial vaccines. We are currently establishing PoC for this novel bacterial vaccine concept in Urinary Tract Infections (UTIs) caused by E. coli with the GlyProVac antigen GPV02. GPV02 holds pan E. coli vaccine potential of not only UTIs, but also diarrhoea, neonatal sepsis and the severe infections associated with Healthcare associated UTIs.

Technology

The novel BEMAP Technology

The GlyProVac BEMAP technology is a powerful sample enrichment method based on mass spectrometry, which allows comprehensive identification of any type of O-linked protein glycosylation. BEMAP is an extension of an SDU proprietary method, which was originally developed for enrichment of phosphopeptides. The BEMAP reaction efficiently substitutes O-linked carbohydrate moieties with a 2-aminoethyl phosphonic acid (AEP) group using base-catalysed β-elimination followed by Michael addition of the tag, thus allowing for selective peptide isolation using titanium dioxide.

Using BEMAP we have discovered that bacterial O-linked glycosylation is much more extensive than previously thought (see table below) and is especially important to Enterotoxigenic Escherichia coli (ETEC) compared to the commensal E. coli counterpart.

The bacterial monosaccharide building blocks are absent from eukaryotic cells and thus constitute a distinguishing feature of bacteria with important roles in pathogenesis. Most, if not all the protein-based vaccines produced nowadays are produced in the non-pathogen bacterium, thereby disregarding the site-specific O-linked glycosylation.

We believe that O-linked glycoproteins are an emerging reservoir of attractive targets for antimicrobial intervention.

Funding Achievements

Private Placements

2023: GlyProVac raised 627,000 EUR (4.7 mil. DKK) in private placement from current and new investors. In the same round, and due to the forced closure of Syddansk Innovation (SDI) as a Danish innovation environment, SDI and the Danish Agency for Higher Education and Science sold the majority of their shares, mainly to existing shareholders.
2021: GlyProVac raised 530,000 EUR (4.0 mil. DKK) in equity funding through business angel investments. In addition, to the new group of investors, which count Allan Rosetzsky and Hans Christian Bukkehave, existing investor Niels Herman Kristiansen also took part in this private placement.
2020: GlyProVac secured 574,000 EUR (4.3 mil. DKK) in a combination of equity investments from founders, SDI and business angel Niels Herman Kristiansen combined with a COVID-19 syndication loan from Growth fund Denmark.
2018: GlyProVac ApS is founded and owned by Anders Boysen backed by Science Ventures Denmark (SVD) and personal investments from co-founder Ann Zahle Andersen and co-inventors of the original BEMAP technology, Jakob Møller-Jensen, Martin Røssel Larsen and Giuseppe Palmisano. In 2018 GlyProVac ApS received equity funding from Syddansk Innovation (SDI) and Danish Agency for Higher Education and Science (previously SIU).
