CALL DESCRIPTION AND OBJECTIVES

Chronic wounds are the hard-to-heal wounds that arise for a variety of reasons, including responding to an underlying disease that represents a challenge for global public health. Treatment for different types of wounds comprise dressing or topical agents with a variety of purposes, including maintenance of a moist healing environment; reduction of bacteria infecting wound; and prevention of infection. The most common causative organisms associated with wound infections include many MDR species such as methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pyogenes, vancomycin-resistant Enterococci (VRE), Pseudomonas aeruginosa, and carbapenem-resistant Acinetobacter spp. (CRAsp). The medical need for novel antimicrobial MDR treatment options globally is undeniable. However, modern drug discovery and development is a lengthy and arduous process, that most often culminate in high failure rates due to safety and toxicity issues, among many other issues. Thus, the research community is willing to invest in various drug discovery strategies, one of which is drug repurposing or repositioning aimed to find new uses for existing drugs, often combined.

One of the limitations of traditional combined therapies lie in their inability to guarantee the simultaneous delivery of various drugs in all districts and to bacterial cells, above all if related to a dense inoculum. Recent studies identified the heart of the problem lies in the intricacies of combined therapy. In particular, the absence of chemical interactions between different drug molecules means that, when administered together, these molecules reach individual bacteria separately.

The smart drug release systems as hydrogels, nanocarriers, patches and microneedles together with multi-target drugs can contribute to solve some of the medical needs of patients suffering from chronic wounds.Significant advances have also been made in the development of functionalized nanomaterials which can acts as stimuli-responsive systems allow the delivery of antibiotics directly to the site of infection, The use of appropriate delivery systems can ensure effective doses because they can reach intracellular targets (S. aureus), increasing bioavailability at the site of action and bacterial exposure. Moreover, some delivery systems can increase permeability across the bacterial cell wall, especially in case of gram-negatives. Thus, improved delivery and synergistic combinations between existing antibiotic and other antimicrobial substances can interfere with such mechanisms that can promote antibiotic-resistance tendency like quorum-sensing mechanisms, biofilm formation, efflux pumps functionality and the host immune response, ultimately overcoming resistance.

Projects responding to this call should aim to develop smart antimicrobial delivery systems as patches, microneedles (MNs) loaded with hydrogel or multidrug systems for the management of antibiotic resistant articular or skin infections able to promote interferences with many mechanisms of antibiotic-resistance tendency like quorum-sensing mechanisms, biofilm formation, efflux pumps functionality and the host immune response, ultimately overcoming resistance.

REPORTING AND OTHERS



EVALUATION PROCESS

Proposals will be evaluated on the basis of the following evaluation criteria:

Proposals will be considered admissible for financing if they obtain at least 70 out of 100 points. Evaluation will be carried out by a panel of 3-5 international and highly-qualified scientists, who are not directly involved in the INF-ACT Research Program. Reviewers will sign a declaration to exclude possible conflicts of interest before accessing the scientific proposals to be evaluated.
