                                                        biopsy is necessary to
verify a potential clinically significant cancer diagnosis."
   2.                                                   Consistent with your

10.      For each diagnostic test and decision support system described in this
section, please
         revise to discuss in greater detail the technical development of each
test including the
         remaining stages of technical development, regulatory filings or other
requirements (i.e.
         the necessity of clinical studies, trials or other clearance or
approvals) and associated costs
         and timelines. To the extent clinical studies or trials will be
required, please discuss these
         requirements and any plans, costs and timelines to complete these
studies or trials. Please
         include enough details so investors can clearly appreciate where each
test resides in your
         development pipeline and the steps, costs and timelines necessary to
obtain final
         regulatory approval.
11.      We note your disclosure elsewhere that you entered into an exclusive
partnership with
         Labcorp in 2023 pursuant to which Labcorp has the exclusive right to
develop and
         commercialize Proclarix in the United States. Please update your
product pipeline figure
         and introductory disclosure to clarify this partnership.
12.      We note the inclusion of certain diagnostic candidates and decision
support systems in
         your pipeline table, including Prediction (Rx), Prosgard Software and
Prostate Cancer
         Decision Support. Given the limited disclosure related to these
programs, please explain
         why they are sufficiently material to your business to warrant
inclusion in your pipeline
         table. If they are material, please expand your disclosure in the
Business section to
         provide a more fulsome discussion of these programs, including a
description of
         development activities conducted. Alternatively, remove any programs
that are not
         currently material from your pipeline table.
13.      We note your reference to a "Cockpit" in your pipeline table. Please
clarify what this
         means or otherwise advise.
14.      We note your pipeline table appears to depict Proclarix twice in the
graphic, as a Decision
         Support System and a Diagnostic. However, your disclosure elsewhere
appears to indicate
         that "Proclarix already consists of a decision support system
integrating different values in
         a risk score" and appears to be one "Proclarix diagnostic program."
Please revise your
         table or otherwise advise if the decision support system is separate
from the diagnostic
         test.
Clinical Studies, page 70

p-value and how it is used

16.      With respect to the clinical studies, please clearly describe the
primary endpoints, and
         whether these endpoints were met. To the extent that there were
secondary endpoints,
         please clearly describe, and disclose whether such endpoints were met,
or otherwise
         advise.
17.      Please provide the basis or data for the statement on page 71 that
Proclarix was more
         accurate when compared to PSA density and online calculators, as well
as the conclusion
         that Proclarix outperformed PSA density in the selection of candidates
for prostate biopsy.
         You may provide an objective summary of the data that you used to draw
such
         conclusions.

In addition, please
         clarify, if true, that you conducted the clinical evaluation, or
otherwise advise.
Market Opportunity
Proclarix, page 74

19.      We note your disclosure that the "worldwide market for in vitro
diagnostic (   IVD   )
         products was valued at $117.8 billion in 2022." However, we note that
"Proclarix has been
         validated and approved for use in men with elevated total PSA (2.0 to
10.0 ng/mL), a
         normal DRE not suspicious for cancer and an elevated prostate volume
(35 mL)." Please
         add balancing disclosure to clarify the addressable market for your
specific product of
         product candidate.
Competition
Competitive Advantages of Proclarix, page 78

20.      With respect to referencing the insurance company as a "Payer," please
disclose, if true,
         that this is a potential or desired stakeholder. In this regard, we
note your disclosures on
         pages 60 and 73 that Proclarix is currently not reimbursed in Europe,
and therefore
         patients pay for Proclarix out of pocket.
