Microbix & Ulisse Biomed Collaborate on HPV Controls & Assays (original press release)

Onboarding Tools and Quality Controls for Extended Genotype HPV Assays

MISSISSAUGA, Ontario and TRIESTE, Italy, Nov. 10, 2023 (GLOBE NEWSWIRE) -- Microbix

Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and

exporter, announces a collaboration with Ulisse Biomed S.p.A. (BIT: UBM, Ulisse), a company

developing innovative diagnostics, theranostics, and therapeutics. The companies are collaborating

to make Microbix’s Quality Assessment Products (“QAPs™”) available and optimized to support the

clinical use and accuracy of Ulisse molecular tests for high-risk types of Human Papilloma Virus

(“HPV Assays”).

Molecular (i.e., “PCR”) HPV Assays are used to diagnose infections and distinguish between the

virus types that generate higher or lower risks of fatal cancers. HPV is a family of approximately 100

sub-types of virus, of which 14 are directly implicated to cause human cancers – most notably

cervical tumors. Molecular tests for high-risk types of HPV identify at-risk patients years before

cancers arise, thereby permitting them to be carefully monitored to prevent the development of

invasive and potentially lethal tumors. However, HPV Assays must be stringently monitored to

ensure their accuracy – ideally with Microbix QAPs.

Ulisse has obtained EU “CE mark” approval for its high-risk extended genotype HPV Assays, which

will now be commercialized on an automated sample-to-result closed system with an installed

base of over 1,500 instruments. Moreover, Ulisse’s HPV Assays are validated with the most widely

used open platforms and with Hyris bCUBETM, a miniaturized PCR instrument particularly suitable

for small-medium laboratories that Ulisse is proposing to clients in conjunction with its assays.

Ulisse has validated Microbix’s HPV QAPs as tools to support the ongoing accuracy of its HPV

Assays and will recommend their usage in its instructions for use (“IFUs”). Additionally, Microbix has

created custom ONBOARDx™ kits of QAPs to assist the Ulisse sales teams in demonstrating the

HPV Assays to prospective customers, as well as for training operators and for qualifying new HPV

Assay installations.

Phil Casselli, SVP of Business Development at Microbix, commented, “We met the Ulisse senior

team at a conference in Europe. Shortly thereafter we began working with them as they {nalized

the performance evaluation of their assays. We are proud to be selected as their preferred controls

and to be referenced on their IFUs. This is another success as we bring these sophisticated highrisk

HPV control products to the global markets for HPV screening”.

Bruna Marini, COO of Ulisse, also commented, “We were looking for a set of controls that fully

covered the range of high-risk HPV types and Microbix is the only company to have such a portfolio.

After an extensive evaluation process, we concluded the performance of Microbix QAPs are exactly

what Ulisse needs and the interactions with their team are delightful.”
