00:00:00
thank you very much thank you for the invitation and give me the
00:00:03
chance uh to speak about uh how we approach m. have
00:00:07
and how we approach uh to to to bring a diagnostic device
00:00:13
to the patient yourself in the meantime i change the title
00:00:18
but but it's not that important um just a glance about human is so we
00:00:26
are privately owned um small a medium and
00:00:31
the price uh roughly nineteen voice
00:00:34
found that forty years ago forty one years ago we are located
00:00:37
your bottle and we have affiliates in five different countries
00:00:42
ah our mission is to develop the manufacturer and
00:00:45
to promote in in vitro diagnostics particularly
00:00:49
um in in uh you should be brought up so technology we are using or
00:00:55
most most of them are based on him the chemistry so eliza later flow essays
00:01:00
uh you need to be made to guesses but we also uh or for some
00:01:04
and semantic test and uh one seller s. a. in in allergy testing
00:01:10
what we call reef these technologies in this essay is is the entire pie range from
00:01:15
group of a fully automated high throughput systems in in the big
00:01:20
laboratories to the point of care essays even that patient homes
00:01:26
so uh these are the topics i want to speak vertically about
00:01:30
rational requirements challenges tool boxes for self a patient self testing
00:01:36
i want uh to uh uh and to present you
00:01:40
our leaving exceed it uh example which scroll ideal
00:01:45
uh i want to give you some feedback by different stakeholders about this technology
00:01:51
and i want to show you how we would like to transfer these our experience if i broke
00:01:57
ah and that would technologies we find to talk to other applications halted the caesar yes
00:02:04
so the rational but i think we should uh bring
00:02:07
uh the i. d.s close to patients are ah
00:02:12
there are a lot of chronic diseases and these are among the white most widespread
00:02:17
diseases oh most most light that help problems diabetes remote data to um
00:02:23
a remote take these orders invest in testing about this is you could even
00:02:27
uh c. uh at least parts of cardiac diseases are chronic diseases
00:02:33
uh these patients usually uh need a lifelong treatment that lifelong crack care
00:02:39
uh these diseases and most awfully presenting faces of remission
00:02:44
relapse that's very important to money toward base
00:02:47
uh if you molly tortillas usually these uh to an
00:02:53
you should uh do we and on time only touring the so that you can do
00:02:58
uh you can make feel protected stations very fast uh it's also important that
00:03:05
you should detect the potential orderly upstairs early as possible and you react as early as possible so
00:03:12
less intervention times usually lead to less hospital stays less either treatments
00:03:18
pasta missions and ultimately also tool to less it costs
00:03:23
and these early intervention strategies requires that patients are closely money torque of course not
00:03:30
only a beef by marcus but also beep regular clinical uh i'm able asians
00:03:37
and the patient can do the monitoring by her or
00:03:42
himself so we should bring the test to them
00:03:48
so some uh requirements we fought before we started project uh he's
00:03:54
important for self monitoring to the patient's home so it will be home
00:03:59
base which will be easy to use it's cleavage will be interactive
00:04:02
uh and beside the two uh for the patient to do this he
00:04:09
shall not require any other thing except his own smart phone
00:04:14
ah of course these tests will generate that quantitative and objective results
00:04:21
for in our case we need a quantitative probably quantitative result
00:04:26
or let's say at least the let's say quantitative result and we should be it
00:04:31
should have a high correlation b. b. for the lab results all these
00:04:35
not only requirement this this was the most challenging part the side of the software development of the whole project
00:04:42
to give the patient a biochemical face which works on to to to to we we for easy read out system
00:04:49
so a each all allow flexible feces more need to ordering uh
00:04:55
it allows a remote contact between or ritual our remote uh remote contact and close partnership
00:05:01
between patients and the treating physician or or any other have kept a professional
00:05:07
and b. b. think each all the if the patients more responsibility in managing
00:05:13
he's for only sees so it's it's all about patient empowerment
00:05:21
ah some challenges apart from the biochemical preston to
00:05:26
read out system the challenges of primarily in
00:05:30
in in that in that in a software development in smart on itself smart phones are
00:05:36
on the one side we could to spot are very performing very different to have very different to ah
00:05:45
we are in a at highly regulated area so we
00:05:49
need to develop a soft than a complying to
00:05:53
i so standards and many many other standards and the sometimes contradicts tool user friendliness
00:06:00
so you could to ease your work flows but you are not allowed to because of
00:06:05
regulations and so on so forth so another big issue is the thought the protection
00:06:10
so we have all encrypted uh to the uh uh in the late to standards
00:06:17
on one side on the other side you would like to have an
00:06:20
immediate access to test result which is also contradicting a little bit
00:06:25
so so we have solved this we have different views are labels and different uses c. different
00:06:31
data on in in in uh the the web portal a big
00:06:38
issue is is the storage and transfer of medical data
00:06:42
uh it's very different real real regulated thinking different countries so different regions
00:06:48
and um the the key at the smog form or the application uh and uh um
00:06:57
i think this mopping doing this uh should be married
00:07:01
illustrated automated you should uh
00:07:08
it should easily look uh uh no in beach every and each country
00:07:15
are these the patients staying and um so we need a a localisation forty for
00:07:22
marcus so at that at the end to the the smart phone displays
00:07:27
the core wrecked a illustrations the right language and so on
00:07:30
and so forth so the tool boxes you need
00:07:35
uh for patients self test things first of all uh you need a by a marker
00:07:41
beach is uh and establish invalidated by market which is an objective theses marker
00:07:47
and this is a prerequisite and these are a teaspoon replace it is is a very
00:07:53
he sees full field in the case of intestinal bowel disease which is
00:07:57
chronic lifelong usually starts very early um
00:08:02
and uh it's it it has a relapse signalling between course the by a
00:08:07
marker we uh established by marker to follow uh these uh these these
00:08:14
the scalp protecting these propane of to from the s. one hundred family um
00:08:20
eat on one side it is used by the use for diagnosis
00:08:25
and differentiation between i. b. d. and all the diseases
00:08:30
and numerous studies have shown that it can also be used protect the season therapy monitoring
00:08:37
usually the results can be grouped in free categories like
00:08:41
normal below one other michael graham programs too
00:08:45
he'll be speak from remission normal coastal healing as it's been kinda caught
00:08:50
there is a moderate level in between eight and forty disease grace own and
00:08:59
apple for about three hundred uh this is our high battles usually
00:09:04
you find values that these values up to several
00:09:08
thousand inactive inflammation or in a relapse
00:09:13
so the second part in the this a biochemical tests here uh we have decided for uh
00:09:19
nope or for an old but maybe not so uh how to fashioned technology letter flow essay
00:09:26
so you can easily uh detect better by marker is present or not
00:09:31
so it the bear market is present it binds the test line and be for a second uh
00:09:36
uh antibody labelled beef cold in our case you can detect is also at best line
00:09:42
if uh uh no and uh by mark or or no um a couple cookies present uh
00:09:49
the gold label is scattered all only by the antibody in the c. line so here
00:09:56
the c. line shows you that the test has worked correctly so very easy principle
00:10:03
very easy to understand and the first part
00:10:08
you need a he's he's he set a convenient read it read out
00:10:13
system we have decided for smart phone is a readout system uh
00:10:19
we have developed a an application called colour and these collect uses the
00:10:25
smart from camera to acquire the image of the test cassette
00:10:29
so uh as as soon as the test had the salon so
00:10:34
you take your smart phone put on the camera approach
00:10:39
approach uh the uh and the test cassette them while approaching the
00:10:43
press cassettes as years of picturing he's he's he's make
00:10:47
and as soon as as as the the act finds and a sharp
00:10:51
a sharp uh i'm picture are sharp enough it freezes and
00:10:57
this is a kind of a freeze for picture so then
00:10:59
it calculates a test light control line ratio and
00:11:04
and be flawed specific a standard curve parameters um
00:11:11
it calculates the result and displays it on smart phone
00:11:20
ah the fourth part you need is a web portal equally the backend
00:11:25
you need to do something which manages all the data so patient paper oh
00:11:31
product specific data and so on so it's encrypted this two way communication beefy collette
00:11:39
has already explained there are different user labels available so
00:11:45
each user sees different amount and settings of data
00:11:52
ah there is also the entire result history here of
00:11:56
a patient is just maybe one patient uh
00:12:01
he's he's he's on this web portal this web portal organise is also the exchange of of data between
00:12:08
the the um patients marked for them be fun emails system
00:12:14
of b. c. or small form of of the doctor
00:12:20
so our living example is the i. b. though so
00:12:23
we have integrated these four parts into one system
00:12:27
so this is the tool kit i. b. talk a piece short for id doc i. b. d. doctor
00:12:33
uh it's a tool for self monitoring of people about the status of the packed and
00:12:42
the qualification of for patients to use this is not
00:12:45
an over over the counter and the bias
00:12:50
he he he called he qualified only few years under treatment
00:12:54
and on the control of the treating physician so
00:12:58
only then he gets a possible work uh to to enter into the i. b. top and he
00:13:03
gets a such a task it's uh by description the only thing he has to provide his
00:13:11
he's her own smart phone
00:13:14
ah and patent that this is working like this it's even a little bit more complex
00:13:19
than having a prick testing as you put two we've looked low cost money touring
00:13:25
patient has to extract his own stool because the sample is is ordered by markers is measured things too
00:13:31
so we have developed the signal and an easy device which
00:13:35
allows the collection and quantitative collection quantitative extraction so
00:13:41
a patient uh collects to uh makes us eat waits for certain time to to the soul
00:13:48
for a a or to extract the the culprit taking out of this to uh
00:13:55
a tax that effects the test to say it uh loads to
00:13:59
discuss it um by using the small this both allows
00:14:04
a quantitative to to uh that that wanted that they've uh drops drop one quantitative
00:14:10
drop comes out of these device onto the loading port of this cassette
00:14:17
after this the patient uh starts 'cause mark form
00:14:22
hand off twelve minutes the smart phone rings
00:14:26
and the patients take takes a picture s. eyes going before uh the result he's he's
00:14:32
he's calculated automatically as soon as the results calculated takes about two seconds or so
00:14:38
the patient got these uh uh gets these um uh i'm
00:14:44
layout the result either be for quantitative number or not this can be decided by the treating physician
00:14:51
by the setting on the web portal and we can add some
00:14:54
notes today mice to was barely cracked or something like that
00:14:58
and as soon as he saves this the result is sent to the portal to portal not be fights the doctor
00:15:06
patient x. y. has done the test dot no result because we decide for security reasons no result are
00:15:14
sent around so that the doctor has to go to the portal and look after these results
00:15:22
uh_huh
00:15:24
ah some some performance data so we have to wally
00:15:28
date all these things um so first boss
00:15:33
the performance of the smart phones per se it's a very busy slide only want to to concentrate on two two things ah
00:15:40
it's very as i said at the very beginning difference mark phones give
00:15:45
different road data because of their i q.'s because of their cameras
00:15:52
of of the resolution of the cameras and if you would not correct the commerce
00:15:56
and you would use this a generic standard curve parameter as i've explained
00:16:01
you will uh get a very uh the diversity
00:16:06
salts over the concentration range uh the uh
00:16:11
these the um grey line feces that is the right chord concentrations determined by
00:16:17
by the references them and without correction uh you see
00:16:22
the red lines after you have corrected these ah
00:16:27
sold that that blinds are very close to do that to
00:16:30
the real concentration so this correction is done automatically
00:16:35
uh and that's why each smart phone has to be qualified
00:16:38
to be used and how only off the correction
00:16:43
it's qualified to do we have also measured playstation that reproduce
00:16:47
ability and that they thought and also q. v. c.
00:16:51
uh as compared to our that to our system uh which is uh
00:16:57
use a a little uh letter flow read it uh for uh for the laboratory
00:17:02
and uh the data are very close to a or north for
00:17:06
for some data even better than than the quantum leap
00:17:14
we then we have done a method comparison in the lack so is do we
00:17:20
get the same results not only for the readout but for the whole yes
00:17:25
so we have done a about fifty extraction fifties collects miles we have low
00:17:30
that that the that the i. b. dock and have done the photos
00:17:34
and got the results we took this this uh colour twelve exactly devices broke them away and
00:17:41
measured the same extract he he in in they have called will
00:17:44
buy say beaches uh because the guy behind throughput essay
00:17:48
and that the and uh we have so um we have not the perfect
00:17:52
correlation but we have a a slope close to one and we have
00:17:58
roughly null bias between the two systems so we
00:18:03
really get the same result in the i. b. dock us
00:18:07
with beef uh be fun establish hyphen put laboratory method
00:18:12
so this is also a little bit basic but uh just want to show you we
00:18:15
have done about ten a clinical performance thought they'd be free patience in real life
00:18:23
uh two of time in the meantime r. p. review would prefer published in peer review review journal
00:18:29
so usually the setting is that and i didn't talk to start at home
00:18:35
and uh the patient takes a sample from the same school with
00:18:42
which he he was he had has been and he
00:18:45
was doing at the i. b. dock and send it to the lack intellects to was extract that once again
00:18:54
uh huh and nash should either on you i saw or on
00:18:57
the comparably data or on the on the um have culpable
00:19:02
and and some some of the data we got is that the prediction of
00:19:09
of a menu below one hundred micrograms program so so well i and
00:19:16
the cool in the study was how long beal my
00:19:22
patients be stable for the next time moments
00:19:28
ah how long there will be no node a baby no relapse and
00:19:33
this is presented here so so these these negative predictive value or more or less the
00:19:38
same for the i. p. doc at home versus the laboratory method so about
00:19:44
eighty five to ninety percent uh of of of of the make negative results really turned
00:19:50
out that that it was no remission at their oscillation between the next four months
00:19:56
ah
00:19:58
uh the opus it was done ah how ballad last night to talk value pretty
00:20:04
can f. call value above three hundred micrograms program meaning there is active inflammation
00:20:11
uh there is a relapse and also the specificity and the positive predictive really almost quite high
00:20:19
i'm not just talking about data may may um most probably
00:20:22
the most complex studies the seer and we uh the
00:20:26
conclusion is that we have a self sufficient agreement to use this new test put the seas money touring
00:20:32
uh because you have a lot of concord and samples you have some samples which are all
00:20:38
over estimated by the i. b. doc the reason here is the rose to sample
00:20:45
cult protecting his not stable intros to samples some of the samples are
00:20:49
only display for more than five days at room temperature so we would argue and we have all to start this
00:20:56
ah a look that that that uh the ideal values
00:21:00
most probably more correct it's not over overestimate about
00:21:04
but just to sample just to try to to to relate to tear radiated well come on next uh
00:21:11
spell this word uh during the transport to the to the lad and that's most probably not
00:21:16
over estimation about bill the result in the lab was just wrong because corporate in boston
00:21:23
down
00:21:26
ah we have also done some human factor start they some usability start this ah
00:21:33
we have done about six thought this uh either as poor you usability studies or or as
00:21:39
a part of the all the studies i have presented to you and uh usually
00:21:45
the patients feel very well instructed they got about the fifteen minutes
00:21:49
training by they have care professional before they could use it
00:21:52
and they they have the t. v. at tutorial tutorials and yet they have a um
00:21:58
an easy um instruction for use it if you feel better well instructed if this
00:22:05
ah they think
00:22:09
they think we have done the test correct they were
00:22:13
also able to perform these these test because at
00:22:16
the end the c. result on the portable or the or the study i'm a p. ice
00:22:24
and very interesting result from one study was that
00:22:29
patients are asked do you prefer to do the test yourself a tool or do
00:22:35
you prefer to send to send in the stool sample so eighty five
00:22:39
uh percent said no why prefer to do test at home by myself
00:22:45
ah all these performances big tall
00:22:50
independent of h. and educational level as far as it was a a examined
00:22:58
and ninety seven percent of these sam out of this um study
00:23:02
participants said uh i would use these also in future
00:23:10
so be backed by the stakeholders
00:23:13
so i i did a piece in use we have about seventy last active
00:23:19
clinics which have installed the id doc in twenty one different countries
00:23:25
uh about fifteen hundred patients are actively using these
00:23:31
really in real life not been stop this
00:23:34
but they did the ad and the portal is available in twenty different languages in
00:23:39
the in the meantime you have six thirty six different validated smart phones
00:23:44
uh uh uh uh but very important feedback is opposed
00:23:50
to bitch with just a baby publish next week
00:23:54
at u. g. w. which we'll state it supported from island using might be doc has lead
00:24:00
to fewer hospital visit to reduce number of and those copies and two significant cost savings
00:24:08
we have a lot of farmer companies move beach are highly
00:24:11
interested uh in using these to get with their rocks
00:24:16
and we have a lot of interest by universities also offering different kind of perhaps uh
00:24:23
i have um have money touring apps scoring apps uh and they
00:24:28
would like to combine or tube to they would like to
00:24:31
to get the ivy doc resulting their rap so we have a lot of i a. p. i. projects going on
00:24:38
another thing is that we are allowed to sell this essay as a self test so we have got
00:24:44
uh i'm a a certification uh by not divide party for self testing
00:24:51
we have a a a the allowance use it industry on since a few months also
00:24:57
it's active a certified as it possibly device uh for self testing in canada
00:25:04
for us very important the patient feedback here's just a a few
00:25:10
statements ah patients have done in their start is like uh
00:25:15
i think i bit off is very useful in determining michael protecting
00:25:19
it's incredibly easy to use i think it's it's creamy handy
00:25:24
or a lot of patience i said at the at the beginning yeah so that was
00:25:28
a little bit on tour on safe but now i'm very pro city if
00:25:32
and uh one lady uh said it's absolutely amazing
00:25:37
that such tests are coming to the market
00:25:42
oh ah you can also find some more um into use and be and
00:25:49
and and and and statements with patients and nurses on you too
00:25:53
the summary
00:25:56
they think it leads to many benefits for the patients it
00:26:00
needs also to many event benefits to the physicians
00:26:04
ah and they think at the end therapies could be optimised and that just it immediately
00:26:13
the studies have to be down regulators have to be okay with this
00:26:17
we are not at the time being steal that to talk to
00:26:20
the size to better therapy will be adapted change and so on so
00:26:25
the patients is the patient is not allowed to do with
00:26:28
to to tease by himself but just we are we are
00:26:34
running start is to get the farmer companies that the b. b. c.
00:26:39
he can replace the code beef can in future how many minutes do we have
00:26:47
which one minute so i'd go very quickly
00:26:51
we have we have um ah
00:26:55
three different areas we want to develop for ah ah and t. i. b. talk to
00:27:01
for to ah applications that with two for two medical and paraplegic fields one is
00:27:08
that we want to integrate uh the the uh the
00:27:12
i. b. talk into it to order acts
00:27:15
of of of of for parties article universities i
00:27:19
folded explain this this is one project
00:27:23
so uh the puppet patient reported outcome is this is very
00:27:28
useful by such combinations and we can very strongly integrate
00:27:36
the second is
00:27:40
new diseases
00:27:43
therapy monitoring of antique enough trucks biological like h. it's very
00:27:47
it's very expensive very important to money toward we do
00:27:52
it now we have already test on that want to read it in serum people to bring these tests now
00:27:59
in capillary plop onto this platform this is called i built one
00:28:05
one and that's the last thing we are now planning
00:28:09
putting together a package we call it i could talk to it's to
00:28:12
see all the that the call is a fully integrated approach
00:28:16
so we'll we'll have smart phones at the patients be it be
00:28:19
like point of care either at doctors lactic small laboratories
00:28:23
uh we have a we have laboratory information systems and
00:28:27
we want all to integrate this one system
00:28:32
and at what what's missing here is the boom back and of course we want uh to have all the results
00:28:40
to get there and the men manage all all uh the things together in in in our back and
00:28:46
so summaries it think self monitoring patients element on gen general needs
00:28:54
for the health care professional at the quality of care for the chronic patient but
00:28:59
the quality of life for the payers improve costs improve care at lower cost
00:29:06
uh just in the current edition of the journal m. help our
00:29:11
system was discussed a little bit and blank wall these
00:29:15
it's an exciting time for the industry the rapid in your
00:29:19
game changing point in how we monitor injury patients
00:29:22
at the point of care so with these thank you
00:29:24
went hello from the human true thank you ah
00:29:34
trying to remote should not very interesting and very nice example of our
00:29:41
product be relaunched endures i the ration it's out now and ah
00:29:52
they're triangle doctor ration producer and you can't
00:29:57
afford for product or so around
00:30:02
you're almost a ready for launch launch bright but the wrong one question for eh
00:30:11
for doctor uh with rubber any questions before launch
00:30:19
oh please oh okay
00:30:23
the u. e. system that you put together is really very
00:30:26
interesting and actually we're going to question the ranch cues
00:30:31
the sample shoes did you preached on privacy and encryption that's right
00:30:37
obviously is appropriate for united states should maybe your is your it's obviously
00:30:42
not necessarily the keys for union underground or to watch retrenchment
00:30:47
how are you thinking about the distribution of those outside the educated
00:30:51
popular should remember all the problems that you mentioned into
00:30:55
watch the rock were remembered novice users problem but received krishna levels
00:31:01
or lines of the bribes you could charge was uh
00:31:04
let's say first we haven't in our clear goal was not to go into for a concrete
00:31:10
barracks in and doing a h. i. v. testing or this kind of test things
00:31:16
however we have been approached by the peel them feeling that gates foundation about a month
00:31:24
ago and they are very interested in i. b. dock and we are now
00:31:28
he's costing very openly and and and that it's very early
00:31:35
to to adapt the ideal from eighty four for their for their plans
00:31:40
uh to adopt it for for to make it much easier
00:31:45
uh be placed a date and integration maybe there will be in two three years
00:31:50
you will see a our concept bills will be applied in third world countries
00:31:59
how most probably yes well up but still still that the clinics are
00:32:05
not very well equipped so and do trooper homes were roswell quote
00:32:12
but the technology would allow that that that that that it's used
00:32:15
by e. by night quite naive people by by late uses
00:32:20
because uh it's all it's also use by and lets it by mail educated play may uses
00:32:28
i mention terrific switched rooms thank you
00:32:35
oh
