Judith: Welcome to Berry's In the
Interim podcast, where we explore the

00:00:03.210 --> 00:00:07.230
cutting edge of innovative clinical
trial design for the pharmaceutical and

00:00:07.230 --> 00:00:09.690
medical industries, and so much more.

00:00:10.600 --> 00:00:11.250
Let's dive in.

00:00:12.375 --> 00:00:14.054
Scott Berry: All right, welcome everybody.

00:00:14.054 --> 00:00:18.585
Back to part B of I Spy two.

00:00:19.304 --> 00:00:24.105
I hope you got the episode, the previous
episode where we are visiting here with

00:00:24.105 --> 00:00:32.505
Don Berry and we are revisiting the I
SPY two trial and we left off, uh, where

00:00:32.534 --> 00:00:39.974
he's using MRI markers, auxiliary markers
to speed up the adaptive algorithm to

00:00:40.034 --> 00:00:43.784
model the rate of PCR six month PCR.

00:00:44.414 --> 00:00:49.429
And he was now talking about
one particular application where

00:00:50.144 --> 00:00:53.864
the time machine is so valuable.

00:00:53.864 --> 00:00:59.204
So how, what is a time
machine in a clinical trial?

00:01:01.349 --> 00:01:06.629
Don Berry: So let me tell you,
in the context of ice I two, um,

00:01:09.059 --> 00:01:13.259
we're, uh, 2014,

00:01:13.275 --> 00:01:13.695
Scott Berry: 14.

00:01:14.339 --> 00:01:18.269
Don Berry: uh, we've got, uh,
several arms in the trial.

00:01:19.019 --> 00:01:21.239
Um, one of the arms.

00:01:22.200 --> 00:01:27.120
Uh, used, uh, Pertuzumab, which
was an anti her two therapy.

00:01:27.599 --> 00:01:36.840
It was used in addition to Trastuzumab,
uh, also called Herceptin, um, in

00:01:36.840 --> 00:01:43.890
her two, uh, positive, uh, women, uh,
that is with her two positive tumors.

00:01:44.910 --> 00:01:49.860
And, um, we had other therapies as well.

00:01:49.860 --> 00:01:57.150
The standard arm in her two positive
disease included Herceptin and Paclitaxel

00:01:57.150 --> 00:02:03.930
and, uh, doxorubicin, um, in this
six month period that we talked about

00:02:03.930 --> 00:02:06.059
it, six months of the, of therapy.

00:02:07.230 --> 00:02:07.829
Um,

00:02:10.170 --> 00:02:18.809
and it's, uh, it, it so happened
that, um, gen, uh, Genentech.

00:02:19.875 --> 00:02:27.914
Uh, had been investigating Pertuzumab,
uh, in her two positive disease.

00:02:28.664 --> 00:02:34.125
Um, and there was a, another trial,
another neoadjuvant trial that was

00:02:34.545 --> 00:02:43.844
comparing it plus Herceptin, uh, to just
Herceptin plus the, the chemotherapies

00:02:43.844 --> 00:02:50.385
of, uh, uh, paclitaxel and, uh,
doxorubicin and Cyclophosphamide.

00:02:51.224 --> 00:02:53.414
Um, so,

00:02:55.425 --> 00:03:04.184
uh, the, uh, FDA gave accelerated
approval to Genentech's Pertuzumab.

00:03:04.245 --> 00:03:04.575
Scott Berry: to ext

00:03:06.704 --> 00:03:10.485
Don Berry: And that meant that,
uh, Genentech could sell the drug.

00:03:11.384 --> 00:03:17.684
Um, and they had obligations about
coming back with, you know, the

00:03:17.684 --> 00:03:23.054
longer term endpoint, but it was based
on an an, an improvement PCR rate.

00:03:24.704 --> 00:03:34.304
Um, and our physicians and our patients,
our patient advocates, uh, and our data

00:03:34.304 --> 00:03:40.695
safety monitoring board said You have to
drop the standard arm for those patients.

00:03:41.534 --> 00:03:44.954
You can't give the standard arm
because it doesn't include pertuzumab.

00:03:47.594 --> 00:03:51.945
Um, and I said, okay, we'll do that.

00:03:51.975 --> 00:03:52.305
Scott Berry: that.

00:03:53.085 --> 00:03:55.244
Don Berry: Um, we did it

00:03:55.844 --> 00:04:00.224
by zeroing out the randomization
to the standard arm.

00:04:01.260 --> 00:04:08.970
Uh, we luckily had pertuzumab in the
trial already as one of the experimental

00:04:08.970 --> 00:04:16.470
arms, and so we were able to, uh,
sort of compare to Pertuzumab, but

00:04:16.470 --> 00:04:20.400
there were only a few patients that
were in, and so it wasn't a big deal.

00:04:21.059 --> 00:04:23.820
So I went to Scott and I said,

00:04:24.080 --> 00:04:24.320
Scott Berry: said,

00:04:25.200 --> 00:04:26.430
Don Berry: what am I gonna do?

00:04:27.000 --> 00:04:32.490
I, I'd like to be able to use the
controls that we already have in

00:04:32.490 --> 00:04:39.600
that, in the her two positives that
did not get pertuzumab, that some

00:04:39.600 --> 00:04:41.520
of which still don't have surgery.

00:04:42.600 --> 00:04:45.630
Um, and I'd like to use them.

00:04:46.950 --> 00:04:48.059
For control.

00:04:49.110 --> 00:04:57.660
Um, but I don't want to keep using them,
you know, for, for five years from now

00:04:58.139 --> 00:05:02.820
when, uh, other things will have happened
and the disease may have moved on.

00:05:03.329 --> 00:05:12.329
And so maybe I should discount them
somehow for, uh, the, um, for the amount

00:05:12.329 --> 00:05:15.119
of time that they've had in follow up.

00:05:15.119 --> 00:05:18.539
And, you know, when they
entered the trial, what do I do?

00:05:19.380 --> 00:05:20.849
And Scott said,

00:05:20.974 --> 00:05:21.264
Scott Berry: said,

00:05:22.170 --> 00:05:23.789
Don Berry: you know,
I know how to do this.

00:05:24.539 --> 00:05:25.320
I did it.

00:05:25.530 --> 00:05:32.730
I did it in baseball and in golf
and in hockey, uh, and Scott,

00:05:32.970 --> 00:05:35.250
uh, to you, the time machine.

00:05:35.849 --> 00:05:41.610
Scott Berry: Yeah, so we in in sports,
there's the age old question of how do

00:05:41.610 --> 00:05:44.369
you compare players of different eras?

00:05:45.059 --> 00:05:49.139
How do you compare a Mark
McGwire to a Babe Ruth?

00:05:49.380 --> 00:05:53.639
How do you compare Tiger Woods to Jack
Nicklaus They never played together.

00:05:54.900 --> 00:06:00.360
The beautiful thing about sport is
they didn't play together, but they

00:06:00.360 --> 00:06:03.840
played with players that played
with players that played with

00:06:03.840 --> 00:06:05.369
players that did play with them.

00:06:05.369 --> 00:06:11.489
So, babe Ruth May have played with Jimmie
Foxx They overlapped in their careers.

00:06:11.799 --> 00:06:14.670
Jimmie Foxx overlapped with Ted Williams.

00:06:14.670 --> 00:06:20.010
Ted Williams overlaps with
Mickey Mantle and Reggie Jackson.

00:06:20.280 --> 00:06:22.770
And Hank Aaron overlapped a lot of people.

00:06:22.980 --> 00:06:24.420
There's a bridging.

00:06:24.825 --> 00:06:28.845
Over time of players at different eras.

00:06:29.265 --> 00:06:36.225
And if you can estimate the effect of
time on the players, sports is almost

00:06:36.225 --> 00:06:41.715
a little bit more complicated 'cause
players age themselves, drugs don't age,

00:06:42.045 --> 00:06:47.325
but that if you could estimate the effect
of time, you can isolate the individual

00:06:47.325 --> 00:06:51.945
effects of different players and compare
them even if they never played together.

00:06:52.335 --> 00:06:59.625
Well here in a brand new kind of trial,
a platform trial, this exact problem

00:06:59.625 --> 00:07:05.475
comes out where arms are in the trial
at different times and now you want to

00:07:05.475 --> 00:07:10.425
compare an arm to patients that were
enrolled at a control at a different time.

00:07:11.115 --> 00:07:15.135
It's exactly the same scenario where
it's only time that's different

00:07:15.405 --> 00:07:17.445
in the scenario to make this.

00:07:19.949 --> 00:07:23.130
Don Berry: So we, we put it in the trial.

00:07:23.880 --> 00:07:28.739
Uh, we're going to use the,
uh, all of the controls.

00:07:29.520 --> 00:07:34.619
Uh, and there is this, uh, time
machine that's Scott, uh, talked about.

00:07:35.309 --> 00:07:42.420
And in the example I gave in the
previous and part A of Pertuzumab, uh.

00:07:43.409 --> 00:07:49.740
Pertuzumab the control arm At the
time that we did, uh, the analysis

00:07:49.740 --> 00:07:55.950
and graduated, uh, the control arm had
about a 20% in triple negative breast

00:07:55.950 --> 00:07:59.280
cancer had about a 20% path CR rate.

00:08:00.150 --> 00:08:08.429
And the, in, on the basis of the one
patient that we had from, uh, Pertuzumab

00:08:08.429 --> 00:08:11.340
who had the results of surgery.

00:08:11.340 --> 00:08:18.240
The result of surgery was A-A-P-C-R
and these other controls, uh, these

00:08:18.240 --> 00:08:24.840
other, uh, patients, um, that we use
the MRI to predict, predict and to

00:08:24.840 --> 00:08:30.960
conclude that the result was going to
be, you know, 60% for, uh, Pertuzumab.

00:08:31.770 --> 00:08:35.099
Um, we very little information.

00:08:35.880 --> 00:08:42.389
About the experimental arm, of course,
but that information was so compelling

00:08:42.780 --> 00:08:44.969
that it was to the right of 0.2,

00:08:46.380 --> 00:08:48.509
uh, with high probability.

00:08:49.110 --> 00:08:52.679
And so it met the graduation
threshold, which was a predictive

00:08:52.679 --> 00:08:55.110
probability calculation.

00:08:56.639 --> 00:08:58.980
So, and, but we didn't stop there.

00:08:58.980 --> 00:09:01.590
We did it for, for all of I spy two.

00:09:02.040 --> 00:09:06.929
From that point forward, all of I spy
two was based on the time machine and

00:09:06.929 --> 00:09:12.000
this, uh, the FDA calls them contemporary
controls, controls that were in the

00:09:12.000 --> 00:09:14.610
trial, but not at the same time.

00:09:15.690 --> 00:09:16.199
Um.

00:09:16.619 --> 00:09:21.300
And they've agreed to use that approach.

00:09:21.389 --> 00:09:22.110
It's really

00:09:22.650 --> 00:09:27.929
amazing, uh, the time machine
approach in registration trials.

00:09:28.409 --> 00:09:33.119
So the two trials that I mentioned,
one in, uh, glioblastoma, the other

00:09:33.119 --> 00:09:39.659
one in pancreatic cancer, uh, they
use the, the time machine as a

00:09:39.659 --> 00:09:41.579
fundamental thing from the get go.

00:09:42.179 --> 00:09:47.250
It isn't just when you had to stop
the, the experimental, the, uh,

00:09:47.250 --> 00:09:51.360
control arm that this applies,
but it applies for everything.

00:09:51.989 --> 00:09:52.590
And

00:09:53.070 --> 00:09:53.279
as

00:09:53.279 --> 00:09:58.230
Scott mentioned, you know, uh,
uh, Ted Williams in his list was

00:09:58.230 --> 00:10:00.570
way back in the, in the middle.

00:10:01.500 --> 00:10:04.170
Um, we.

00:10:05.205 --> 00:10:12.675
Uh, we want to use, um, uh, Ted
Williams during the that period.

00:10:12.765 --> 00:10:13.695
Uh, and,

00:10:14.265 --> 00:10:16.905
uh, we want to use an experimental arm.

00:10:16.905 --> 00:10:19.605
We want to compare Ted Williams.

00:10:20.115 --> 00:10:26.745
We get, we get a notion of what is the
control rate during, uh, Jimmy Fox's

00:10:26.745 --> 00:10:30.495
period during, uh, Hank Aaron's period.

00:10:31.260 --> 00:10:40.800
Uh, and so we in the algorithm explicitly
compare Ted Williams to Jimmy Fox.

00:10:41.400 --> 00:10:46.260
We explicitly compare
pertuzumab to other therapies.

00:10:46.470 --> 00:10:47.760
It's just we don't tell.

00:10:48.360 --> 00:10:52.800
Merck as the, uh, the drug's,
uh, uh, sponsor owner.

00:10:53.700 --> 00:11:00.510
Uh, we don't tell Merck what
the Eli Lilly drug was doing.

00:11:00.540 --> 00:11:05.040
We don't tell Eli Lilly what the Merck
Drug is doing, but we're comparing

00:11:05.040 --> 00:11:12.900
everything to everything in order to,
uh, uh, assess what is the control rate.

00:11:13.375 --> 00:11:13.775
Scott Berry: control.

00:11:15.075 --> 00:11:20.550
So, uh, behind the scenes there's one
model that's estimating the individual

00:11:20.550 --> 00:11:25.380
interventions in the trial and provides
that estimate to a standardized control.

00:11:25.740 --> 00:11:28.590
And it's using all of the
data from all the arms.

00:11:28.590 --> 00:11:33.270
'cause it enables us to estimate
the effect of subtypes, the effect

00:11:33.270 --> 00:11:37.860
of time, all of these variables
in providing that estimate.

00:11:37.860 --> 00:11:42.270
Then you can hand a particular
sponsor the estimate for

00:11:42.270 --> 00:11:44.490
their arm relative to control.

00:11:44.700 --> 00:11:47.160
And the machine is used, all of the data.

00:11:48.360 --> 00:11:52.530
Now you, you mentioned
the, um, graduation.

00:11:53.070 --> 00:11:57.240
Uh, which by the way I think is a
new word that came out of ICE by

00:11:57.240 --> 00:12:02.940
two as sort of some level of success
that wasn't statistical significance

00:12:02.940 --> 00:12:08.400
traditionally, but the success in ICE
by Two was innovative in and of itself.

00:12:08.790 --> 00:12:13.410
What was graduation or success
from a phase two trial?

00:12:16.335 --> 00:12:21.180
Don Berry: So the way we defined
graduation was it's going to do well.

00:12:22.470 --> 00:12:23.070
Um.

00:12:23.790 --> 00:12:27.150
And we did predictive probabilities, which

00:12:27.540 --> 00:12:31.920
is kind of essential in this business.

00:12:32.625 --> 00:12:40.644
That you, you, and integral to the kinds
of things that Barry does, um, we look

00:12:40.644 --> 00:12:44.664
at the data, well, we, I say we look
at the data, the algorithm looks at the

00:12:44.664 --> 00:12:46.944
data programmed to look at the data.

00:12:47.334 --> 00:12:50.309
It's kinda like, uh,
artificial intelligence, um,

00:12:50.334 --> 00:12:54.925
um, and, and learns, uh, what

00:12:55.794 --> 00:12:56.365
data.

00:12:57.084 --> 00:12:59.394
Uh, what, what are the

00:12:59.499 --> 00:12:59.800
Scott Berry: the

00:13:00.474 --> 00:13:04.074
Don Berry: current probabilities of
benefit for the various therapies?

00:13:04.854 --> 00:13:06.354
And we do prediction.

00:13:06.354 --> 00:13:14.064
We say, well, is this, does the data
at hand suggest that this is a drug?

00:13:14.574 --> 00:13:18.564
That this is a drug that can be
marketed, that's gonna be successful

00:13:18.924 --> 00:13:21.084
in the context of ISI two?

00:13:22.404 --> 00:13:24.924
Is it gonna be successful
in a phase three trial?

00:13:26.154 --> 00:13:31.044
And in a phase three trial predicting
the results of a phase three trial?

00:13:31.764 --> 00:13:35.604
Uh, the Bayesian approach, of
course, is critical in this.

00:13:36.114 --> 00:13:37.224
Uh, the,

00:13:37.854 --> 00:13:44.154
uh, PCR rate in the experimental drug
has a probability distribution called

00:13:44.154 --> 00:13:48.504
a current probability distribution or
posterior probability distribution.

00:13:49.284 --> 00:13:52.344
Uh, but what really matters is the future.

00:13:52.869 --> 00:13:55.510
So there's data, there's
two kinds of uncertainty.

00:13:55.510 --> 00:14:01.539
One is in what is the PCR rate,
that parameter, uh, and the other

00:14:01.539 --> 00:14:06.909
is what are the data that come
forward, the inevitable uncertainty

00:14:07.329 --> 00:14:10.479
associated with the future results.

00:14:10.809 --> 00:14:17.859
So these two uncertainties combine to
allow for calculating a prediction.

00:14:19.030 --> 00:14:23.139
What is the probability that a
future trial will be successful?

00:14:23.499 --> 00:14:27.939
If it has these characteristics,
and that drives everything in.

00:14:27.939 --> 00:14:28.780
I spy too.

00:14:29.050 --> 00:14:36.789
It drives the adaptive randomization,
it drives the graduation, it drives the

00:14:36.789 --> 00:14:39.399
possibility of stopping for futility.

00:14:40.180 --> 00:14:42.369
There's a stopping for futility.

00:14:43.119 --> 00:14:47.769
Um, that's across the board that we
calculate based on the predictive

00:14:47.769 --> 00:14:50.800
probability, uh, distribution.

00:14:51.339 --> 00:14:58.180
But there's also, as Scott suggested, the,
the possibility of stopping in a subtype.

00:14:59.349 --> 00:15:03.909
Um, because the randomization
probability is so small that it, the

00:15:03.909 --> 00:15:07.209
patient, you know, no patients are
gonna be assigned to this subtype.

00:15:07.720 --> 00:15:09.010
That actually happened.

00:15:09.159 --> 00:15:12.519
Neratinib was one of the
early drugs in the trial.

00:15:12.519 --> 00:15:17.319
We published them in New England Journal
of Medicine, the results of the Neratinib,

00:15:17.979 --> 00:15:21.639
uh, trial and indicated that there was.

00:15:22.434 --> 00:15:25.615
Some subtypes where it got zeroed out,

00:15:25.734 --> 00:15:25.944
Scott Berry: out,

00:15:26.694 --> 00:15:31.044
Don Berry: but meanwhile, in other
subtypes, it was doing very well.

00:15:32.004 --> 00:15:39.175
So it stopped randomizing in the
subtypes where it was not doing

00:15:39.175 --> 00:15:42.804
well and increased the probability.

00:15:43.284 --> 00:15:49.824
And the other subtypes graduated since,
uh, has been approved by the FDA for

00:15:49.824 --> 00:15:53.454
the, you know, marketing, uh, approval.

00:15:54.175 --> 00:16:01.794
Um, and nobody, as Scott indicated,
nobody knew that this happened.

00:16:02.004 --> 00:16:07.254
I mean, if this happened in a two arm
trial and you, you said, uh, the DSMB

00:16:07.254 --> 00:16:09.115
tells you, you gotta stop the control,

00:16:09.209 --> 00:16:09.569
Scott Berry: control,

00:16:10.554 --> 00:16:11.964
Don Berry: that would be a big deal.

00:16:12.550 --> 00:16:14.019
How could you stop the control?

00:16:14.019 --> 00:16:20.499
Could you then go in and, uh, get
another control or, or wait a while

00:16:20.499 --> 00:16:22.060
until you figure out what to do?

00:16:22.990 --> 00:16:31.060
We never announced that Neratinib was no
longer being assigned to those subtypes

00:16:31.089 --> 00:16:35.740
of, of women, um, until after the trial.

00:16:36.100 --> 00:16:42.669
Of course, the, the, uh, DSMB
was involved, uh, and the DSMB

00:16:42.669 --> 00:16:44.589
was enthusiastic about doing it.

00:16:44.589 --> 00:16:49.030
In fact, before they realized that it
was going, that it wasn't assigning

00:16:49.030 --> 00:16:55.390
probabilities, uh, wasn't assigning,
uh, neratinib to any of these subtypes.

00:16:56.019 --> 00:17:02.229
Uh, one of the DSMB members said, we
should stop Neratinib in that subtype.

00:17:02.229 --> 00:17:03.550
I said, you don't have to.

00:17:04.720 --> 00:17:06.310
algorithm has already stopped it.

00:17:07.780 --> 00:17:08.140
Scott Berry: Yeah.

00:17:08.709 --> 00:17:09.280
Yep.

00:17:10.749 --> 00:17:11.379
Okay.

00:17:11.379 --> 00:17:14.800
So a little bit of the numbers of I Spy.

00:17:14.800 --> 00:17:16.059
So what are we talking about?

00:17:16.059 --> 00:17:25.870
I SPY two started rolling in 2010
and it ran through 2022, and I

00:17:25.870 --> 00:17:32.169
believe in that time, 23 different
investigational therapies went through

00:17:33.979 --> 00:17:34.469
Don Berry: Correct,

00:17:35.320 --> 00:17:39.939
Scott Berry: and nine of those
were successfully graduated.

00:17:40.149 --> 00:17:44.590
So you talked about pancreatic
cancer, you talked about GBM where.

00:17:45.369 --> 00:17:46.749
Very little works.

00:17:46.749 --> 00:17:49.749
And it's the, the huge challenge
of these platform trials is

00:17:49.749 --> 00:17:51.610
to, to try as much as you can.

00:17:51.610 --> 00:17:56.110
And breast cancer therapies worked
and some of them in subsets of women,

00:17:56.110 --> 00:18:01.240
the right subsets of women, but
nine of 23 successfully graduated.

00:18:01.240 --> 00:18:05.800
And, uh, I, I think you mentioned
that four of the nine have

00:18:05.800 --> 00:18:07.599
received marketing approval.

00:18:08.110 --> 00:18:09.280
Don Berry: Yeah, something like that.

00:18:09.280 --> 00:18:12.039
But there's still, the others are still

00:18:12.760 --> 00:18:13.119
Scott Berry: To be

00:18:13.374 --> 00:18:14.024
Don Berry: Yeah, no.

00:18:14.289 --> 00:18:14.740
Scott Berry: Yeah.

00:18:14.829 --> 00:18:15.220
Yeah.

00:18:15.550 --> 00:18:15.939
Yeah.

00:18:16.300 --> 00:18:22.119
So from the perspective of
the impact on breast cancer,

00:18:22.629 --> 00:18:25.329
the I-SPY 2 trial was amazing.

00:18:25.329 --> 00:18:31.180
Before I sort of turn to the, the, the,
the larger impact of I Spy two and other

00:18:31.180 --> 00:18:35.919
things, I, I think there's a few people
that you wanted to make sure that due

00:18:35.919 --> 00:18:39.249
credit, one of them is Janet Woodcock.

00:18:41.439 --> 00:18:41.949
Don Berry: Yes.

00:18:42.249 --> 00:18:47.739
So this is really a story
about three dynamic women.

00:18:48.399 --> 00:18:50.709
Uh, one of course is Laura Esserman.

00:18:51.550 --> 00:19:00.489
Um, uh, the other I mentioned is Anna
Barker, uh, who was, uh, very helpful in

00:19:00.494 --> 00:19:05.499
the, the funding aspect and then give and
giving advice about how, how to do this.

00:19:06.340 --> 00:19:14.050
Uh, and the other is Janet Woodcock,
who was at the time the, um, head of

00:19:14.050 --> 00:19:20.590
CDER uh, at the FDA and, um, has been.

00:19:21.514 --> 00:19:27.694
Uh, pushing adaptive designs and, for
example, this thing about adaptive

00:19:27.724 --> 00:19:35.194
randomization, she is, um, publicly
announced adaptive randomization

00:19:35.524 --> 00:19:37.474
is adequate and well controlled.

00:19:38.494 --> 00:19:39.154
Now, if you know

00:19:39.514 --> 00:19:43.084
regulatory stuff, you know
that that's, that's the

00:19:44.074 --> 00:19:47.134
criterion for a phase 3 trial.

00:19:47.639 --> 00:19:52.319
For a pivotal trial, for a trial
that, uh, a registrational trial,

00:19:52.949 --> 00:19:54.269
adequate and well controlled.

00:19:55.049 --> 00:20:02.009
So she has been enormously helpful,
um, in I-SPY 2 and in setting

00:20:02.009 --> 00:20:09.749
up, uh, GBM Agile and uh, uh,
the pancreatic cancer, uh, trial.

00:20:10.066 --> 00:20:13.306
Scott Berry: so, uh, Anna
Barker, Laura Esserman.

00:20:13.306 --> 00:20:16.936
Janet Woodcock, a huge role
and a couple people, perhaps a

00:20:16.936 --> 00:20:18.406
little bit behind the scenes.

00:20:18.796 --> 00:20:24.766
So Meredith Buxton was there for quite a
while, had a huge impact on ice by two.

00:20:26.681 --> 00:20:30.116
Don Berry: And the current
circumstance with Meredith Buxton is.

00:20:30.841 --> 00:20:34.171
Scott Berry: Well, she is now,
she's graduated, you will.

00:20:34.561 --> 00:20:41.521
Um, uh, she successfully, so she now
runs, uh, uh, she's now the CEO of GCAR,

00:20:41.521 --> 00:20:47.311
global Coalition for Adaptive Research,
and they run multiple platform trials.

00:20:47.611 --> 00:20:54.961
Uh, so she, she did, uh, incredible work
on a lot of the logistics and making,

00:20:55.201 --> 00:20:58.411
making this go and now does this for GCAR.

00:20:58.741 --> 00:21:03.121
And, uh, a little bit on a personal
side from Barry Consultant's side is.

00:21:03.496 --> 00:21:10.396
Berry Consultants built the code to
run Ice Spy Two, and Ashish Sunil

00:21:10.486 --> 00:21:15.886
at Berry was intricately involved in
making sure that code ran, working

00:21:15.886 --> 00:21:19.066
with Meredith running for years.

00:21:19.276 --> 00:21:24.046
Uh, Ashish, Sunil had a huge
impact on making that trial run.

00:21:24.346 --> 00:21:30.196
He has sort of, uh, uh, very, very
sadly, uh, came down with a LS,

00:21:30.556 --> 00:21:35.416
uh, and, and uh, in that, but he
had a huge impact on ice by two.

00:21:36.976 --> 00:21:41.161
Don Berry: Uh, so I should
mention, um, Kyle Waltham.

00:21:41.281 --> 00:21:47.551
Kyle was at, uh, MD Anderson with me when
we set this up, and he wrote the original

00:21:47.551 --> 00:21:52.651
code, um, and it, it worked great.

00:21:53.371 --> 00:21:59.041
Um, and then when we had to vary
from the code for, you know,

00:21:59.041 --> 00:22:07.021
we're adaptive, um, we went back
to MD Anderson and, uh, they, we.

00:22:07.191 --> 00:22:09.321
I had lost the code.

00:22:10.281 --> 00:22:12.561
So I went to Scott and I said,

00:22:13.491 --> 00:22:14.271
what can I do?

00:22:15.381 --> 00:22:20.601
Um, and he said, well,
I'll, I'll rewrite it now.

00:22:20.601 --> 00:22:27.471
You have to understand the original
code was really long and, and

00:22:27.471 --> 00:22:32.361
developing and, and writing and deciding
what we wanted to do and all this

00:22:32.361 --> 00:22:35.451
adaptive randomization and et cetera.

00:22:36.381 --> 00:22:43.071
Um, and it took and including
with some funding from Anna

00:22:43.071 --> 00:22:46.971
Barker, um, for Kyle's salary.

00:22:47.331 --> 00:22:51.921
I never, uh, had any kind of a of a.

00:22:52.571 --> 00:22:53.981
Uh, salary or anything.

00:22:53.981 --> 00:22:59.051
It was all voluntary and all of
Barry consultants' work was, was

00:22:59.051 --> 00:23:01.691
voluntary, uh, in ice py too.

00:23:02.921 --> 00:23:14.951
Um, so Scott took, I think three days
instead of, instead of, uh, two years,

00:23:14.951 --> 00:23:18.791
it took Scott three days, but of course
he knew what we, what the goal was.

00:23:19.351 --> 00:23:19.571
Scott Berry: Yep,

00:23:20.501 --> 00:23:23.321
Don Berry: Uh, and that's,
that's what we've used since and

00:23:23.321 --> 00:23:26.786
model modified it, uh, since I.

00:23:27.361 --> 00:23:27.541
Scott Berry: Yep.

00:23:28.591 --> 00:23:36.041
So I-SPY 2 in many ways was the,
uh, a forefather a a a foremother

00:23:36.061 --> 00:23:42.361
for, for platform trials, one of
the, the early platform trials.

00:23:42.361 --> 00:23:46.531
Phenomenal success, success in
the disease, but is really in

00:23:46.531 --> 00:23:48.691
many ways changed the industry.

00:23:49.051 --> 00:23:51.301
GBM Agile doesn't exist.

00:23:51.301 --> 00:23:55.831
Pancreatic Cancer Action Networks
trial PanCan, that, that, that trial

00:23:55.831 --> 00:24:03.841
Precision Promise doesn't exist
and COVID hits and, um, operation

00:24:03.871 --> 00:24:06.571
Warp speed, the ACTIV trials.

00:24:07.306 --> 00:24:13.846
Are largely I-SPY 2 for treatment
of therapeutic COVID and Janet

00:24:13.846 --> 00:24:21.166
Woodcock's leading the ACTIV network
and it's all platform trials.

00:24:21.166 --> 00:24:28.516
So the impact of I-SPY 2 and this idea
that you said, you, you bet the farm at

00:24:28.516 --> 00:24:37.486
the time, and you and Laura kind of went
on this strange, uh, risky path that

00:24:37.606 --> 00:24:39.766
cooperative groups might not embrace.

00:24:39.766 --> 00:24:45.166
And you get, you know, you get innovative
funding, you're getting Safeway

00:24:45.166 --> 00:24:47.566
grocery stores to help fund this.

00:24:47.896 --> 00:24:52.486
Um, and it's, it changed
the world literally.

00:24:53.550 --> 00:24:54.580
Don Berry: Thank you, and I agree.

00:24:55.820 --> 00:24:55.940
I

00:24:56.880 --> 00:24:57.270
Scott Berry: Yep.

00:24:58.530 --> 00:24:58.890
Alright.

00:24:58.890 --> 00:25:03.060
So they're sort of b before I
spy two and after I spy two.

00:25:03.060 --> 00:25:10.170
So, uh, phenomenal trial, uh, phenomenal
effort and, and an amazing story.

00:25:10.710 --> 00:25:14.310
So Don, I appreciate you
walking us through that story.

00:25:14.830 --> 00:25:15.860
Don Berry: thank you for

00:25:16.730 --> 00:25:17.820
leading the walk.

00:25:17.995 --> 00:25:18.235
Scott Berry: walk.

00:25:18.795 --> 00:25:19.635
Yeah, right.

00:25:20.065 --> 00:25:25.770
Well, thank you everybody for, for
doing two parts of I Spy two and in

00:25:25.770 --> 00:25:28.380
the next time we are in the interim.

00:25:29.130 --> 00:25:29.520
Thank you.

00:25:29.790 --> 00:25:30.220
Don Berry: Thank you.

00:25:30.570 --> 00:25:30.870
Scott Berry: Thank you.
