Myconostica Announces Presentation Of Positive Multi-Centre Multinational Clinical Evaluation Data For MycassayTM Pneumocystis
Manchester, United Kingdom, September 13th, 2010 / b3c newswire/ - Myconostica Ltd, the UK-based medical diagnostic company developing and commercialising rapid and highly specific tests for life-threatening fungal infections, today presented positive data from a multi-centre prospective evaluation of MycAssayTM Pneumocystis, the Company's CE marked diagnostic product for detection of Pneumocystis DNA in respiratory samples. A Multinational Prospective Evaluation of a Commercial Pneumocystis Real-Time PCR test (Paper M-417a). The clinical data were presented at the 50th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Boston on September 12th. The study was carried out in four hospitals located in Austria, Switzerland and the USA.
Data from the evaluation were presented for the study group by lead investigator, Jacques Bille, MD, CHUV Lausanne, Switzerland. A key outcome from the study showed that the sensitivity and specificity of the test were 93% and 91% respectively, when compared with final clinical diagnosis.
131 unique subjects were evaluated of which 110 gave analysable data. The underlying clinical conditions that contributed to the at-risk patient status were transplants (50), non malignant conditions (32), leukemia (13), solid tumours (11) and HIV+ (9). Fourteen subjects were clinically diagnosed with PCP and 13 of these were positive using the MycAssayTM Pneumocystis. For the 14th subject, the clinical sample was low volume and poor quality, as noted by the site. 9 patients without pneumocystis pneumonia (PCP) had positive MycAssayTM Pneumocystis results. Of these, on clinical follow up, one subsequently developed PCP. These results suggest that the increased sensitivity of the molecular assay may be indicative of asymptomatic latent disease in the at-risk patient group.
MycAssayTM Pneumocystis, is a novel molecular diagnostic test, specific to Pneumocystis jirovecii. The test is CE marked and Health Canada approved for diagnostic purposes on the most commonly available real-time PCR thermocyclers on the market.
Pneumocystis jirovecii is a fungal pathogen that causes pneumocystis pneumonia, a common and serious opportunistic infection in immunocompromised patients. If undiagnosed and/or untreated it can lead to respiratory failure and death. Unlike most pathogens P. jirovecii cannot be cultured and current diagnosis relies upon radiologic evidence and microscopic methods including immunofluorescence. MycAssayTM Pneumocystis is the first commercially available molecular assay to be evaluated in a multi-centre multinational prospective study looking at the at risk population for this serious and potentially fatal disease.
Dr. John Thornback, Myconostica's Chief Business Officer, said: "MycAssayTM Pneumocystis is a robust, standardardised and easy to use assay, that delivers a result within four hours. The study shows a high sensitivity and specificity for detection of the pathogen with a very high negative predictive value suggesting a possible role for the assay in ruling out the presence of this pathogen."
At the same meeting, a paper was presented on MycArrayTM Yeast ID (M-402), Myconostica's focused microarray based product for the identification of a wide range of pathogenic yeasts. The work carried out by Dr. Farina and presented on behalf of the Medical Mycology Committee, Italian Society of Clinical Microbiology, highlights the ease of use and accuracy of the test in picking up a wide range of pathogens. This test is available globally as a research use only product through Myconostica distributors and directly from the company. Myconostica is exhibiting at the ICAAC conference 12th to 14th September in Boston booth 835 (Hall A).

About Myconostica Ltd. - www.myconostica.co.uk
Myconostica Ltd, a UK-based medical diagnostic company, specialises in rapid and highly specific tests for life-threatening fungal infections. Traditional methods of the detection of fungal infections are well documented as being relatively insensitive and slow. Tests provided by Myconostica aim to allow healthcare professionals to rapidly identify patients infected thus enabling clinicians to prescribe appropriate drug therapy.
Myconostica is developing and commercialising a portfolio of real-time molecular diagnostic tests for life-threatening fungal infections. Over 10 million people are at risk of these infections each year in Europe and North America alone.
