Two Performance Studies on Idylla(TM) MSI Biomarkers Selected for Publication at
                                ASCO Conference

Mechelen,   Belgium,   17 May  2018 -  Biocartis  Group  NV  (the  'Company'  or
'Biocartis'),  an innovative  molecular diagnostics  company (Euronext Brussels:
BCART),  today  announces  that  two  studies  conducted in cooperation with the
Flemish  Institute  for  Biotechnology  (VIB)  regarding  the performance of its
exclusively  licensed  novel  set  of  biomarkers for microsatellite instability
(MSI) that are included in the Idylla(TM) MSI Assay (the 'MSI Biomarkers'), have
been  selected  for  publication  at  the  ASCO  (American  Society  of Clinical
Oncology) Annual Meeting, taking place between 1-5 June 2018 in Chicago, US. The
first  study uses  the prototype  Idylla(TM) MSI  Assay in  finalized design and
shows  superior performance of  the MSI test  compared to reference methods. The
second study underlines the potential of Biocartis' MSI Biomarkers[1] to be used
as  a  companion  diagnostic  to  predict  immunotherapy  outcome in MSI-High[2]
endometrial and colorectal tumors.

MSI  is the result of  inactivation of the body's  so-called DNA mismatch repair
(MMR)  system. Consequently, errors that normally spontaneously occur during DNA
replication are no longer corrected, contributing to tumor growth and evolution.
Detection  of  MSI  is  currently  recommended  for all patients with colorectal
cancer  (CRC). Current MSI  testing methods rely  on manual, lengthy and complex
procedures  involving amongst others obtaining and testing of a second reference
sample.  The fully automated Idylla(TM) MSI  Assay is expected to overcome these
drawbacks,  providing results within 150 minutes from  just one slice of FFPE[3]
tumor tissue, without requiring a reference sample.

The  first study[4] used the prototype  Idylla(TM) MSI cartridges in a finalized
design,  containing  a  new  set  of  seven  MSI Biomarkers, consisting of short
homopolymers  located in the ACVR2A, BTBD7, DIDO1, MRE11, RYR3, SEC31A and SULF2
genes,  to test 348 FFPE colorectal cancer  samples[5] on their MSI status (i.e.
MSI-High(2)  or Microsatellite stable). A  concordance analysis with a reference
methodology[6]  showed an overall agreement of 96.1%. Of the discordant results,
fourteen  cases  were  classified  as  MSI-High by Idylla(TM) but Microsatellite
stable  (11) or invalid (3) by the reference method. Based on these results, the
study  concluded that  the prototype  Idylla(TM) MSI  Assay is capable of faster
detection  with  excellent  sensitivity  and  significantly less invalid results
compared to reference molecular testing for MSI.

The  second study[7], based on 33 samples,  demonstrated that the MSI Biomarkers
reliably  identified MSI-High status in endometrial and colorectal cancer[8] and
that  MSI-High is correlated to the total insertion-deletion (indel) load of the
tumor.  These  indel  mutations  increase  tumor  responsiveness  to  checkpoint
blockade  immunotherapies, which is a type of immunotherapy where the power of a
patient's  immune  system  is  harnessed  to  attack tumors. Checkpoint blockade
immunotherapies  were recently  US FDA  approved for  the treatment  of MSI-High
tumors.  As such, the study concluded  that the MSI Biomarkers could potentially
be used to predict immunotherapy outcome in MSI-High tumors.

Prof.  Diether Lambrechts,  Director of  the VIB  - KU  Leuven Center for Cancer
Biology,  commented: "These studies clearly show  the high clinical value of the
MSI  Biomarkers,  first  identified  in  our  lab  and  now meticulously further
selected  to a set of  seven biomarkers by Biocartis  that are combined with the
advantages of the fully automated Idylla(TM) system. The seven biomarkers show a
remarkable  association with both tumor mutational  burden and total indel load.
This  provides us with  a potential novel  and easy-to-implement tool to predict
tumor response to checkpoint blockade immunotherapy".

Herman  Verrelst, CEO Biocartis,  reacted: "The selected  ASCO studies once more
demonstrate the innovative nature of the Idylla(TM) MSI Assay that we have under
development. In our view, the unique features of this test are of great value to
the  pharmaceutical industry that needs rapid, reliable and easy MSI testing for
a  broad rollout of  their immune-oncology treatments.  Together we could enable
more patients with MSI-High tumors to benefit from these promising immunotherapy

The  launch  of  Biocartis'  fully  automated  Idylla(TM)  MSI Assay (RUO[9]) is
planned for H2 2018.

[1]  The MSI Biomarkers were identified  by Prof. Diether Lambrechts' laboratory
and exclusively licensed to Biocartis from VIB in 2013.

[2]  MSI-High tumors share certain characteristics,  such as high tumor mutation
burden  with a  high number  of insertion-deletion  (indel) mutations, which are
likely  to result  in the  production of  neo-antigens, attracting  the adaptive
immune  system  and  therefore  more  likely  to  respond to checkpoint blockade
immunotherapies.  Antigenicity is  the capacity  of a  molecule or an antigen to
induce  an immune  response that  is to  be recognized  by and  interact with an
immunologically    specific    antibody    or    T-cell    receptor.    (Source:

of  the Idylla(TM)  MSI Assay  prototype", ASCO  Annual Meeting  of the American
Society of Clinical Oncology, 1-5 June 2018, Chicago, US.

[5]  Patient samples of several clinical  sites and different ethnic groups were
included to assess robustness of marker selection.

(Promega MSI analysis system).

associated  with tumor mutation  burden and total  indel load in endometrial and
colorectal  cancers", ASCO  Annual Meeting  of the  American Society of Clinical
Oncology,  1-5 June 2018, Chicago, US. The methodology used for detection of the
seven  biomarkers, TMB (tumor mutation burden,)  and indel load, was whole-exome

[8]  The  study  method  used  the  mutation  landscape  of  14 endometrial  and
colorectal  MSI-High tumors  that were  previously characterized  by whole-exome
sequencing (Zhao et al., Elife 2014), and identified indels in homopolymers that
recurrently  affect MSI-High  tumors (frequency  up to  80% per tumor  type). An
additional  19 MSI-High tumors  were positive  for at  least 2 out  of 7 indels,
while  Microsatellite stable  tumors were  positive for  none of them. The study
further  correlated the number of positive  indels in all available MSI-H tumors
(n=19+14) with mutation load.
