JERSEY, Channel Islands, April 13, 2015 (GLOBE NEWSWIRE) -- Quotient Limited (Nasdaq:QTNT), a commercial-stage diagnostics company, today announced that results generated using the MosaiQ™ methodology demonstrated a high degree of sensitivity and specificity for its Hepatitis B Surface Antigen (HBsAg) assay. The feasibility study was conducted in collaboration with Intuitive Biosciences, Inc., and examined a total of 96 positive and negative samples.
The HBsAg assay exceeded Quotient’s target of sensitivity and specificity for this phase of development, demonstrating that the MosaiQ™ methodology can be applied to HBsAg detection. Findings from the study demonstrated sensitivity of 98.6% (23 detected versus 24 positive samples) and 100% specificity (72 negative samples reported as negative). In addition, the MosaiQTM methodology detected the HBsAg standard of 0.2 International Units Per Milliliter. As a result of these positive study results, Quotient now plans to complete the development and validation of the HBsAg assay, including improvement of the analytical sensitivity for inclusion on the MosaiQTM disease screening consumable for donor testing.
“These positive initial results for our HBsAg assay further support the expanding utility of MosaiQ™ as an innovative and disruptive diagnostics platform with broad commercial application within the donor testing market of transfusion diagnostics,” said Paul Cowan, Quotient’s Chairman and CEO. “We have now established technical feasibility for HBsAg, Cytomegalovirus (CMV) and Syphilis assays and look forward to the development of additional assays for the detection of Hepatitis C virus (HCV), Human Immunodeficiency virus (HIV), Human T-Lymphotropic virus (HTLV) and Chagas disease (T. cruzi). This combination of assays will allow Quotient to offer a full suite of currently mandatory disease screening tests on a single consumable using MosaiQ™.”
Hepatitis B is a viral infection that primarily affects the liver, causing both acute and chronic disease. The hepatitis B virus (HBV) is transmitted through contact with the blood or other bodily fluids of an infected person. Acute symptoms associated with initial infection include vomiting, yellow skin, abdominal pain and fatigue. While the majority of infections do not lead to chronic infection, most people infected around the time of birth develop chronic hepatitis B. Chronic infection can potentially lead to the development of cirrhosis of the liver and liver cancer, often resulting in death. According to the World Health organization, an estimated 240 million people are chronically infected with HBV (defined as HBsAg positive for at least 6 months), resulting in approximately 650,000 deaths each year. It is critical that all donated blood for transfusion purposes is effectively screened for HBV.
MosaiQTM is currently under development and is not available for sale in the United States. Quotient plans to begin field trials for its full donor disease screening consumable (comprising CMV, Syphilis, HBV, HCV, HIV, HTLV and T. cruzi) in 2016. The disease screening consumable for donor testing is being developed for screening both red cell and plasma donations.
