General Overview

Previously the Diagnostic division of Systagenix, WOUNDCHEK™ Laboratories is focused on the development of novel wound diagnostics products to help improve therapeutic outcomes in wound care. Currently, the cost of ineffective treatment is estimated to be $20-25 billion1Data based on savings calculated with the WOUNDCHEK economic model, UK version, with AQP VLU data inputs. – Nherera L. et al. Quantifying the economic value of diagnostics in wound care in the UK. Poster, EWMA 2013. annually. Clinical experts agree the use of point of care wound diagnostic devices could reduce the cost of ineffective treatment and delayed healing by being able to target the right therapy, on the right patient, at the right time, and for the right length of time²World Union of Wound Healing Societies (WUWHS). Principles of best practice: Diagnostics and wounds. A consensus document. London: MEP Ltd, 2008.. A resulting financial benefit to health care systems can be achieved through significant reduction of the expenses associated with poor targeting of treatment, delayed healing, and avoidable complications. WOUNDCHEK™ Laboratories launched the world’s first and only point of care test to detect EPA (elevated protease activity) in chronic wounds in 2012, and over the past several years has become a recognized leader in wound diagnostics. 

Mission

The company’s vision is to provide clinicians with better, accurate, timely, actionable, and easy to access information, leading to improved therapeutic outcomes through point of care wound diagnostics. WOUNDCHEK™ Laboratories aims to be the leading and dominant enterprise in wound diagnostics by providing medical professionals with the diagnostic information to: 

  • Identify wounds which are not healing 

  • Intercept issues and early warnings that cause poor wound healing or initiate wounds 

  • Aid in determination of best therapeutic routes 

  • Monitor the effectiveness of a course of treatment

Activities

Based in the UK and the USA, WOUNDCHEK™ Laboratories' staff are focused on product development, clinical research, and working with its distribution partners to develop the emerging wound diagnostics markeg.

Our research is centred on two critical questions, identified by clinical experts as primary pieces of diagnostic information needed to direct treatment pathways in the majority of chronic wounds:

  • Does the wound have Elevated Protease Activity?

  • Is there an active infection?

WOUNDCHEK™ Protease Status, the world’s first and only point of care test to detect EPA (elevated protease activity), was launched in 2012 and cleared for sale in Europe, the Middle East, South Africa, and Canada.

 

ISO 9001:2008 and ISO 13485:2003 certified quality management system.

Areas of Interest

The strategy of WOUNDCHEK™ Laboratories is to be the leading and dominant enterprise in wound care diagnostics by providing medical professionals with the diagnostic information to: 

  • Identify wounds which are not healing

  • Intercept issues and early warnings that cause poor wound healing or initiate wounds

  • Aid in determination of best therapeutic routes

  • Monitor the effectiveness of a course of treatment

Clinical experts identified numerous markers that could form the basis of new diagnostic tools for use in wound care1World Union of Wound Healing Societies (WUWHS). Principles of best practice: Diagnosis and wounds. A consensus document. London: MEP Ltd, 2008.(see slide above).

The Only Test to Detect EPA

Developed to aid wound assessment and help clinicians target advanced wound care therapies more effectively, WOUNDCHEK™ Protease Status is able to detect EPA (elevated protease activity). As there are no visual cues for EPA, wounds with EPA have so far gone undetected1Snyder R. et al. A survey: The importance of proteases in wound healing and wound assessment. Poster, Wounds UK 2011.

WOUNDCHEK™ Protease Status will help clinicians establish within minutes which wounds may most benefit from a protease modulating therapy, ensuring appropriate and targeted use of these therapies.

Active Infection

Bacteria are in a pathogenic state when they are either in the process of, or they are capable of, causing disease, i.e. infection. One measure of pathogenicity is the production of enzymatic virulence factors called bacterial proteases1Lebrun I, Marques-Porto R, Pereira AS, Pereira A, Perpetuo EA. Bacterial toxins: an overview on bacterial proteases and their action as virulence factors. Mini-reviews in medicinal chemistry 2009; 9 (7): 820-8.. A number of known proteases have been characterised from some of the frequently reported bacteria in chronic wounds2Koziel J, Potempa J. Protease-armed bacteria in the skin. Cell Tissue Res. 2012; 351(2): 325-37.,3Potempa J, Pike RN. Corruption of innate immunity by bacterial proteases. J. Innate Immun. 2009; 1: 70-87.. The impact of bacterial proteases has been documented in a range of acute and chronic medical conditions, including cystic fibrosis, eye infections and wound infections3Potempa J, Pike RN. Corruption of innate immunity by bacterial proteases. J. Innate Immun. 2009; 1: 70-87.,4Twining SS, Kirschner SE, Mahnke LA, Frank DW. Effect of P aeruginosa elastase, alkaline protease, & exotoxin A on corneal proteinases and proteins. Invest. Ophthalmol. Vis. Sci. 1993; 34(9): 2699-712..

The detection of bacterial protease activity in a chronic wound would be indicative of the presence of bacterial pathogenesis which is a precursor to clinical signs and symptoms of infection5Thomson PD, Smith DJ. What is infection? Am. J. Surg. 1994; 167(No. 1A): 7S-10S.,6Dow G, Browne A, Sibbald RG. Infection in chronic wounds: Controversies in diagnosis and treatment. Ostomy Wound Management 1999; 45 (8): 23-40..

Bacterial pathogenesis is undesirable since, at this stage, the wound is in a part of the wound infection continuum that typically requires intervention.

Wound care experts agree that a test for bacterial protease activity (BPA) may provide clinical and economic benefits


In an article published in Wounds International Journal (2015, Vol 6, No 4, pages 22-28), leading wound care experts conclude that a new point of care test for bacterial protease activity (BPA), being developed to identify wounds in which bacteria may delay healing, may assist clinicians in determining when interventions to reduce bacterial burden are indicated, particularly in chronic wounds with no obvious signs of infection.

The article, which included a proposed clinical pathway incorporating the test, further discussed the potential of the test to help clinicians target antimicrobial therapies and help reduce usage of systemic antibiotics.
