Quality Control Materials for Genital Ulcer Disease Molecular Assays

MISSISSAUGA, CANADA, July 26, 2022 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces it is presenting about the utility of its multi-pathogen (“multiplex”) and swab-formatted Quality Assessment Products (“QAPs™”) to monitor molecular assays that detect and distinguish between four sexually-transmitted infections (each an “STI”) that cause Genital Ulcer Disease (“GUD”) – at the 2022 conference of the American Association of Clinical Chemistry (“AACC”) taking place in Chicago, Illinois from July 24-28, 2022.

Its poster presentation is titled “Novel Herpes Simplex Virus, Varicella Zoster Virus, and Treponema pallidum Quality Control Material for use with Genital Lesion Molecular Detection Assays.” The poster details the use of Microbix’s PROCEEDx™FLOQ® HSV1&2/VZV/Syphilis Swab Positive Sample QAPs to monitor the performance, procedures, and workflows of molecular assays that detect STIs from the oral and genital types of the Herpes Simplex Virus (“HSV 1” and “HSV2”), Varicella Zoster Virus (“VZV”) and Treponema pallidum (the spirochete bacteria causing “Syphilis”). The PROCEEDxFLOQ QAPs proved compatible with 13 molecular assays across both commercially-available diagnostic platforms and laboratory-developed tests, and were used to support an external quality assessment pilot study.

These assessments were coordinated by the Microbix team and consolidated data provided from 16 laboratories, notably including the Cadham Manitoba Provincial Laboratory (Winnipeg, Canada) and Labquality Ltd. (Helsinki, Finland), the support of which are gratefully acknowledged.

GUDs are a current and growing global health concern, with over 20 million new cases each year. Traditionally, diagnosis of GUD has relied on clinical assessment of symptoms, which lacks specificity given the similar appearance of ulcers caused by different etiological agents. Such non-specific diagnosis leads to misclassification, delayed treatment, and the development of complications. Although there is now a growing pipeline of molecular assays for sensitive and specific diagnosis of GUD, external quality control materials to verify performance have been largely unavailable. Microbix has overcome challenges in formulation and appears to be the first to develop a multiplex whole-workflow control for GUD assays. This STI-oriented PROCEEDxFLOQ multiplex QAP adds to Microbix’s expanding portfolio, which includes Health Canada, U.S. FDA, EU “CE mark,” or TGA (Australia) in-vitro-diagnostic (“IVD”) regulated REDx™ and research-use-only (“RUO”) PROCEEDx™ SKUs across both liquid-vial and Copan FLOQSwab® formats.
