AlgiPharma awarded four year grant from Norwegian Research Council

AlgiPharma has been awarded a new four year grant from the Norwegian Research Council for the project “Treatment of Chronic Infective Disease with Alginate Oligomer Based Formulations”. This study will focus on extended long term safety studies and formulation changes to further develop the AlgiPharma drug candidate OligoG for the treatment of cystic fibrosis.

AlgiPharma awarded four year grant from Norwegian Research Council

AlgiPharma has been awarded a four year grant from the Norwegian Research Council for the project “Tailored OligoG in the treatment of chronic infectious biofilms”. This study involving an international consortium will investigate microbial sources of raw material for AlgiPharma’s alginate technology and determine optimal oligomer length associated with specific known OligoG antimicrobial properties.

Abstract

The influence of a novel, safe antibiofilm therapy on the mechanical properties of Pseudomonas aeruginosa and Acinetobacter baumannii biofilms in vitro was characterized. A multiscale approach employing atomic force microscopy (AFM) and rheometry was used to quantify the mechanical disruption of the biofilms by a therapeutic polymer based on a low-molecular weight alginate oligosaccharide (OligoG). AFM demonstrated structural alterations in the biofilms exposed to OligoG, with significantly lower Young’s moduli than the untreated biofilms, (149 MPa vs 242 MPa; p < 0.05), a decreased resistance to hydrodynamic shear and an increased surface irregularity (Ra) in the untreated controls (35.2 nm ± 7.6 vs 12.1 nm ± 5.4; p < 0.05). Rheology demonstrated that increasing clinically relevant concentrations of OligoG (<10%) were associated with an increasing phase angle (δ) over a wide range of frequencies (0.1-10 Hz). These results highlight the utility of these techniques for the study of three-dimensional biofilms and for quantifying novel disruption therapies in vitro.
