1
00:00:00,040 --> 00:00:04,600
We will cover the second line 
really world change completely 

2
00:00:04,600 --> 00:00:07,280
with Gardice cells. 
So Gardice cells now are in 

3
00:00:07,280 --> 00:00:11,680
second line with laser cell and 
axis cell and then in the 

4
00:00:11,720 --> 00:00:17,040
accommodation we propose axis 
and liser cell in second hand 

5
00:00:17,040 --> 00:00:19,680
for patients eligible to cartice
cells. 

6
00:00:19,680 --> 00:00:23,120
So cartice cells are for 
patients in the collapse and 

7
00:00:23,120 --> 00:00:27,800
refractory patients collapse 
within the first year and then 

8
00:00:27,800 --> 00:00:30,560
for the patients that are not 
eligible for cartice cells 

9
00:00:30,760 --> 00:00:35,360
Glofigermux or if you are 
collapsing really late, you may 

10
00:00:35,360 --> 00:00:38,440
eventually challenge the 
patients with chemotherapy again

11
00:00:38,720 --> 00:00:43,120
and high dose therapy. 
Please autologous same as home 

12
00:00:43,120 --> 00:00:49,280
conditions welcome. 
To EHE Unplugged, the official

podcast channel from the 
European Hematology Association 

14
00:00:51,920 --> 00:00:54,120
EHE. 
In this episode we are joined by

15
00:00:54,120 --> 00:00:57,800
Professor Maya Jose Kirsten from
Amsterdam University Medical 

16
00:00:57,800 --> 00:01:00,280
Center. 
I'm by Professor Catherine 

17
00:01:00,280 --> 00:01:02,840
Teblumun from the Hospitals Only
in Paris. 

18
00:01:03,000 --> 00:01:06,680
Together, they will discuss the 
recently published EHA guideline

19
00:01:06,680 --> 00:01:09,720
for the diagnosis, treatment, 
and follow up of patients with 

20
00:01:09,960 --> 00:01:13,480
large B cell lymphoma, LBCL. 
They're here to give you an 

21
00:01:13,480 --> 00:01:16,360
overview of the guidelines and 
help you navigate the panel's 

22
00:01:16,360 --> 00:01:18,880
recommendations. 
Welcome and enjoy this episode. 

23
00:01:19,080 --> 00:01:21,880
Hello, I'm Catherine Tibermo 
from Paris Sunway Hospital. 

24
00:01:21,920 --> 00:01:24,000
Hi. 
I'm Maria J Kirsten. 

25
00:01:24,120 --> 00:01:27,080
I'm from Amsterdam. 
We worked together very hard to 

26
00:01:27,080 --> 00:01:29,760
get this guideline on. 
We'll discuss all the insurance 

27
00:01:29,760 --> 00:01:32,560
and outs of the guideline. 
So this is guidelines about 

28
00:01:32,560 --> 00:01:38,800
largely selling from us and the 
first step for the the work up 

29
00:01:38,840 --> 00:01:42,840
of the patients is about staging
the patients. 

30
00:01:42,840 --> 00:01:47,080
So, so how do we stage the 
patients for large B cell 

31
00:01:47,080 --> 00:01:50,440
lymphoma? 
The first thing is to base the 

32
00:01:50,440 --> 00:01:54,400
strategies based on the IPI. 
So we still use this 

33
00:01:54,680 --> 00:01:59,640
international pomastic index 
based on the five factors. 

34
00:02:00,360 --> 00:02:04,960
So the age of the patients which
is really important, the 

35
00:02:04,960 --> 00:02:10,320
interest level, the stage, the 
number of external sites and the

36
00:02:10,320 --> 00:02:14,040
performance status and the 
performance status is really the

37
00:02:14,040 --> 00:02:18,400
key to stratify the patients 
regarding the choice of the 

38
00:02:18,400 --> 00:02:21,880
treatment that we will 
administer to the patients and 

39
00:02:21,880 --> 00:02:26,120
make a choice. 
So the three key factors are 

40
00:02:26,280 --> 00:02:30,840
age, personal status and 
extensions of the disease with 

41
00:02:31,120 --> 00:02:35,160
the stage, the external sites 
and the number of these external

42
00:02:35,160 --> 00:02:36,000
sites. 
Yeah. 

43
00:02:36,320 --> 00:02:39,440
And if we go a step back, 
because of course first we need 

44
00:02:39,440 --> 00:02:43,760
a diagnosis, so we recommend 
excision of a lymph node. 

45
00:02:43,840 --> 00:02:46,000
I think we had a lot of 
discussion about that. 

46
00:02:46,000 --> 00:02:49,840
What's your opinion? 
Should we do needle biopsies or 

47
00:02:49,840 --> 00:02:51,360
should we excise a whole lymph 
now? 

48
00:02:51,560 --> 00:02:55,960
So there is a different school, 
schools for that and the 

49
00:02:55,960 --> 00:03:01,400
technosis is of course based on 
this biopsy either which was the

50
00:03:01,400 --> 00:03:05,440
surgery or the core needle 
biopsy. 

51
00:03:06,280 --> 00:03:11,120
This is a really easy to take 
the second strategy and to have 

52
00:03:11,120 --> 00:03:15,880
a coordinated biopsy, really 
easy to get peripheral biopsy, 

53
00:03:15,880 --> 00:03:20,960
peripheral leaf node biopsy, 
profound sites for the biopsy. 

54
00:03:21,120 --> 00:03:24,760
And this is I think better 
compared to the surgery. 

55
00:03:24,960 --> 00:03:28,520
Why? 
Because the surgery make make 

56
00:03:29,200 --> 00:03:33,240
will take longer time to get the
diagnosis and sometimes we do 

57
00:03:33,240 --> 00:03:38,840
not have this time when we treat
aggressive disease such as large

58
00:03:38,840 --> 00:03:41,720
be selling from us. 
If if possible and not too 

59
00:03:41,720 --> 00:03:45,120
difficult to reach, I think a 
whole lymph node is probably 

60
00:03:45,280 --> 00:03:47,080
better. 
Gives you more information on 

61
00:03:47,080 --> 00:03:48,920
the architecture. 
Yes, yes. 

62
00:03:49,600 --> 00:03:52,080
So, yeah. 
And particularly the micro 

63
00:03:52,080 --> 00:03:56,440
environment, we know that with 
the new drugs now we need to 

64
00:03:56,440 --> 00:03:59,560
have informations regarding the 
micro environments. 

65
00:03:59,680 --> 00:04:04,840
It's always better to have this 
surgery biopsy, but if it's not 

66
00:04:04,840 --> 00:04:09,640
possible, of course coordinated 
biopsy is really important and 

67
00:04:09,640 --> 00:04:11,440
important step. 
And what do you think are the 

68
00:04:11,440 --> 00:04:15,560
minimal methods that need to be 
used to get to a diagnosis at 

69
00:04:15,560 --> 00:04:18,320
this point? 
Which methods, immunochemistry 

70
00:04:18,320 --> 00:04:20,560
or molecular methods are really 
necessary? 

71
00:04:20,680 --> 00:04:24,720
Yes, of course we need to have 
between high grade B cell 

72
00:04:24,720 --> 00:04:29,720
lymphoma transform from indolent
lymphoma as follicular 

73
00:04:29,720 --> 00:04:33,760
meshalzone lymphoma as primary B
cell lymphoma that are really 

74
00:04:34,000 --> 00:04:36,920
particular lymphoma. 
So we need to have 

75
00:04:37,160 --> 00:04:40,640
immunochemistry. 
We need to have also FISH 

76
00:04:41,880 --> 00:04:48,560
diagnosis regarding genes such 
as Mick B cell 2B cell 6 and to 

77
00:04:48,560 --> 00:04:55,000
have eventually the subtypes 
regarding ABC or GCB which is 

78
00:04:55,240 --> 00:05:00,480
not now considered as 
nobligratory marker because we 

79
00:05:00,480 --> 00:05:04,400
know that there is no difference
in term of therapy strategies 

80
00:05:04,400 --> 00:05:08,120
between AB, CS and GCBS largely 
selling from. 

81
00:05:08,120 --> 00:05:12,280
What do you think of NGS to look
at mutational landscape in the 

82
00:05:12,280 --> 00:05:15,120
tumor cells? 
Yes, it's really important and 

83
00:05:15,200 --> 00:05:18,560
interesting to have these 
markers, but right now we have 

84
00:05:18,640 --> 00:05:23,280
no difference in term of therapy
strategies based on NGS. 

85
00:05:23,840 --> 00:05:28,120
I think that we will see more 
evidence of targeted agents 

86
00:05:28,120 --> 00:05:32,560
being more more active for 
example in the MCD type is, but 

87
00:05:32,680 --> 00:05:35,880
this is at the moment not we 
didn't make it part of of the 

88
00:05:35,880 --> 00:05:38,120
guideline because it's not black
and white. 

89
00:05:38,120 --> 00:05:41,400
So we, yeah, we cannot do this 
in an evidence base then? 

90
00:05:41,560 --> 00:05:44,440
Exactly. 
Maybe in the next round of the 

91
00:05:45,160 --> 00:05:47,800
the guidelines, maybe in the 
future, in the near future. 

92
00:05:47,960 --> 00:05:49,480
I'm sure not right now. 
Yeah. 

93
00:05:49,720 --> 00:05:53,320
And what do you think is the 
strategy in terms of imaging 

94
00:05:53,640 --> 00:05:58,160
diagnosis and for AS into a more
end of treatment evaluation? 

95
00:05:58,280 --> 00:06:00,560
Yes. 
So as we said at the baseline, 

96
00:06:00,560 --> 00:06:06,200
it's really important to have a 
good aspect on the extension of 

97
00:06:06,200 --> 00:06:10,880
the disease and even the master 
bulky and to measure the bulky 

98
00:06:10,920 --> 00:06:15,640
more than based on the CT scan. 
But also the PET scan may afford

99
00:06:15,720 --> 00:06:21,760
to have a better evaluation of 
this bulky mass PET scan at the 

100
00:06:21,760 --> 00:06:24,920
baseline. 
And then the PET scan may also 

101
00:06:24,920 --> 00:06:30,840
be repeated with interim 
analysis after 2 cycles, 4 

102
00:06:30,840 --> 00:06:33,920
cycles, and even at the end of 
the treatment. 

103
00:06:33,920 --> 00:06:38,240
So if you are doing interim 
analysis, you may eventually 

104
00:06:38,240 --> 00:06:42,800
skip at the end of the treatment
with PET scan and only do ACT 

105
00:06:42,920 --> 00:06:45,720
scan. 
But it's really important to 

106
00:06:45,720 --> 00:06:50,120
have a sense of the metabolic 
response assessment, which is 

107
00:06:50,280 --> 00:06:53,880
really important to know if we 
have complete response. 

108
00:06:56,640 --> 00:07:00,640
Do you think that there is 
several aspect to assess this 

109
00:07:00,640 --> 00:07:03,000
metabolic response in term of 
the? 

110
00:07:03,520 --> 00:07:05,080
Yeah. 
So at the moment I think 

111
00:07:05,080 --> 00:07:09,640
standard is that we use the Oval
scores or the semi sort of semi 

112
00:07:09,640 --> 00:07:14,160
quantitative assessment of the 
yeah, several shades of Gray. 

113
00:07:14,160 --> 00:07:18,000
So and I think that for the 
moment is satisfactory. 

114
00:07:18,000 --> 00:07:22,280
But I think for interim pets we 
might also start implementing 

115
00:07:22,280 --> 00:07:26,360
the delta SUV because it has 
been shown that if at interim 

116
00:07:26,360 --> 00:07:30,840
pets there is more than 70% 
decrease in the standardized 

117
00:07:30,840 --> 00:07:33,520
uptake value, those patients 
have an especially good 

118
00:07:33,840 --> 00:07:36,400
prognosis. 
I don't think that's implemented

119
00:07:36,400 --> 00:07:39,840
at the moment at most of the 
hospitals, but I definitely 

120
00:07:39,840 --> 00:07:44,800
think Delta SUV and at diagnosis
the metabolic tumor volume will 

121
00:07:45,280 --> 00:07:47,520
gain the momentum in the coming 
years. 

122
00:07:47,800 --> 00:07:53,160
This effectively is the strategy
to evaluate better the patients 

123
00:07:53,560 --> 00:07:56,640
during the first line. 
And so in your opinion what is 

124
00:07:56,640 --> 00:08:00,040
the first line treatment for the
patients with large B cell in 

125
00:08:00,040 --> 00:08:01,960
from us? 
So the common patients, what is 

126
00:08:01,960 --> 00:08:03,840
the best treatment for large B 
cell? 

127
00:08:03,840 --> 00:08:05,760
Yeah. 
So depends of course on stage. 

128
00:08:05,800 --> 00:08:10,400
So for the limited stage 
patients and low risk factors, I

129
00:08:10,400 --> 00:08:12,760
think abbreviated 
immunochemotherapy is the 

130
00:08:12,760 --> 00:08:15,800
standard. 
So mostly 4 cycles of Archo. 

131
00:08:16,080 --> 00:08:19,320
Maybe we can even go lower with 
the negative interim path. 

132
00:08:19,480 --> 00:08:23,600
But for the stage 2 with Milky 
disease or stage 3, four, we, I,

133
00:08:23,680 --> 00:08:26,040
I remember we had some 
discussion about what was the 

134
00:08:26,040 --> 00:08:28,880
best first line. 
And of course again depends on 

135
00:08:28,880 --> 00:08:32,360
age, performance status, but 
also on comorbidities, for 

136
00:08:32,360 --> 00:08:35,880
example, the cardio 
cardiacomorbidities, which would

137
00:08:35,880 --> 00:08:38,679
make treatment with antracyclins
more difficult. 

138
00:08:39,000 --> 00:08:43,240
But for the standard patients 
with a low IPI zero to 1, I 

139
00:08:43,240 --> 00:08:47,760
think Archop 6 cycles is still 
the standard of care for, I 

140
00:08:47,760 --> 00:08:52,280
don't know now 25 years or more.
So we know perfectly effectively

141
00:08:52,280 --> 00:08:56,120
this surface line and based on 
Archop, what about the high 

142
00:08:56,120 --> 00:09:00,480
grade piece of lymphoma because 
we know that Archop is maybe not

143
00:09:00,480 --> 00:09:02,480
so satisfactory for these 
patients? 

144
00:09:03,000 --> 00:09:05,440
Yeah. 
So I create lymphomas especially

145
00:09:05,600 --> 00:09:09,080
if they are double hit. 
And as you know now in the new 

146
00:09:09,400 --> 00:09:12,640
DHL classification, this 
pertains to patients who have a 

147
00:09:12,640 --> 00:09:17,040
mid translocation and BCL 2 and 
it's no longer the MIC and BCL 6

148
00:09:17,200 --> 00:09:20,080
or the triple hits. 
I think they're with regular 

149
00:09:20,080 --> 00:09:23,960
Archop we don't see a good 
enough outcomes and also the 

150
00:09:24,000 --> 00:09:28,200
Polar R chip doesn't seem to be 
better than our shop in that 

151
00:09:28,200 --> 00:09:31,320
particular population. 
So there we would go in a fit 

152
00:09:31,320 --> 00:09:35,840
patient for those just epoch R 
or another intensified regimen 

153
00:09:36,040 --> 00:09:38,880
and also strongly consider CNS 
prophylaxis. 

154
00:09:39,680 --> 00:09:45,400
What about what is your opinion 
regarding this treatment and to 

155
00:09:45,600 --> 00:09:47,720
whom? 
I would like to administer this 

156
00:09:47,720 --> 00:09:50,760
treatment. 
So in the study, the patients 

157
00:09:51,320 --> 00:09:55,360
with an IPI of two to five were 
eligible for for this study. 

158
00:09:55,360 --> 00:09:58,560
So it's a higher risk population
and there was a difference in 

159
00:09:58,720 --> 00:10:03,600
progression free survive also 6%
absolute difference, but no 

160
00:10:03,600 --> 00:10:07,200
difference in overall survival, 
probably because we have good 

161
00:10:07,200 --> 00:10:11,800
selfish salvage options with 
stem cell transplant or Carty in

162
00:10:11,800 --> 00:10:14,480
a second line. 
So yeah, it's implemented 

163
00:10:14,480 --> 00:10:16,320
differently in different 
countries. 

164
00:10:16,440 --> 00:10:19,400
For example in the Netherlands, 
but I think also in France, 

165
00:10:19,400 --> 00:10:22,880
EFOLA is not reimbursed. 
So we still give our job. 

166
00:10:23,040 --> 00:10:27,560
And the last question regarding 
the first line, but we could 

167
00:10:27,560 --> 00:10:31,480
have a lot of more questions. 
What about this external 

168
00:10:31,480 --> 00:10:34,640
disease? 
Sometimes we have patients with 

169
00:10:35,240 --> 00:10:39,920
no involvement or few another 
involvement but external with 

170
00:10:39,920 --> 00:10:44,800
testes for example. 
And we discussed the past few 

171
00:10:44,800 --> 00:10:50,280
years about CNS prophylaxis. 
So how could we deal with this 

172
00:10:50,280 --> 00:10:52,400
prophylaxis and external 
disease? 

173
00:10:52,680 --> 00:10:54,760
I think that's a whole topic on 
itself. 

174
00:10:55,400 --> 00:11:00,040
So much discussion about the use
of CNS prophylaxis. 

175
00:11:00,280 --> 00:11:03,080
I think most centers have 
abandoned intrathecal 

176
00:11:03,480 --> 00:11:05,200
prophylaxis. 
So if you think there's an 

177
00:11:05,400 --> 00:11:09,720
indication for CNS prophylaxis, 
I would go for high dose 

178
00:11:09,720 --> 00:11:12,720
methotrexate. 
So at least three grams per 

179
00:11:12,720 --> 00:11:16,120
meter square and two cycles and 
mostly do it at the end of 

180
00:11:16,120 --> 00:11:18,240
therapy if there's no CNS 
involvement. 

181
00:11:18,360 --> 00:11:23,640
And of course, it needs patient 
to do a baseline CSF assessment.

182
00:11:23,680 --> 00:11:27,000
And yeah, so if you look at the 
extranodal lymphomas, I think 

183
00:11:27,000 --> 00:11:31,040
it's best demonstrated for 
primary testicular lymphoma 

184
00:11:31,040 --> 00:11:34,280
because they have a very high 
rate of secondary CNS 

185
00:11:34,280 --> 00:11:37,440
involvement. 
So we would definitely do it in 

186
00:11:37,440 --> 00:11:41,120
those patients. 
I think the indication for CNS 

187
00:11:41,120 --> 00:11:44,240
prophylaxis has shrinked over 
the years. 

188
00:11:44,520 --> 00:11:46,840
And finally, the last one, 
because I think it's really 

189
00:11:46,840 --> 00:11:48,680
important. 
The strategy is really different

190
00:11:48,680 --> 00:11:52,080
from the other large B cell. 
Lymphoma is the primary media 

191
00:11:52,080 --> 00:11:57,840
cell lymphoma. 
What is your strategy for this 

192
00:11:58,240 --> 00:11:59,400
PMBA? 
Yeah. 

193
00:11:59,840 --> 00:12:01,600
Yeah. 
So these are mostly young female

194
00:12:01,600 --> 00:12:04,640
patients who present with a 
bulky mediastinal mass. 

195
00:12:04,640 --> 00:12:09,480
And of course also here direct 
direct comparison in clinical 

196
00:12:09,480 --> 00:12:12,400
trials is lacking mostly. 
But if you look at the results 

197
00:12:12,400 --> 00:12:17,120
of ARCHOP versus intensified 
ARCHOP like ARCHOP 14 or those 

198
00:12:17,120 --> 00:12:20,040
adjusted EPOCH R or other 
intensified regimens, there's a 

199
00:12:20,040 --> 00:12:22,920
clear difference in the 
progression free survival in 

200
00:12:22,920 --> 00:12:25,880
those patients and also very 
importantly, the rate of 

201
00:12:25,880 --> 00:12:29,320
complete metabolic remission at 
the end of the induction. 

202
00:12:29,520 --> 00:12:32,440
And that's really important 
because in those patients who 

203
00:12:32,440 --> 00:12:36,280
still have active disease, you 
might consider the radiation 

204
00:12:36,280 --> 00:12:39,480
therapy, but these are young 
female patients and giving them 

205
00:12:39,480 --> 00:12:42,760
radiation therapy to the chest 
might also mean an increased 

206
00:12:42,760 --> 00:12:46,000
risk for breast cancers. 
I think achieving the CMR is 

207
00:12:46,040 --> 00:12:48,320
really important. 
I think the i.e. 

208
00:12:48,320 --> 00:12:51,720
LSG did a great job in their 
study demonstrating that in 

209
00:12:51,720 --> 00:12:56,560
patients with CMR you don't need
radiation therapy and that this 

210
00:12:56,560 --> 00:13:00,200
is achieved much more often with
intensified recommends. 

211
00:13:00,480 --> 00:13:04,120
That was interesting to see that
actually our Job 14 performed 

212
00:13:04,120 --> 00:13:07,240
more or less the same as even 
more intensive regimen. 

213
00:13:07,240 --> 00:13:11,560
So we have started to we did 
those just at ebook R, but are 

214
00:13:11,720 --> 00:13:14,760
drifting back to our job 14. 
How about your SO? 

215
00:13:14,800 --> 00:13:17,200
This is exactly the same 
strategy. 

216
00:13:17,360 --> 00:13:20,160
We know you, we are using our 
job 14. 

217
00:13:20,320 --> 00:13:24,480
It's really easy and in this 
population of patients who are 

218
00:13:24,560 --> 00:13:31,640
younger after 14 is really and 
there is no sort of effect, 

219
00:13:32,160 --> 00:13:34,600
major sort of effect. 
So yes, we are. 

220
00:13:35,120 --> 00:13:39,760
We switch the two after 14. 
Yeah, in the primary B cell in 

221
00:13:39,760 --> 00:13:40,720
format. 
Yeah. 

222
00:13:40,720 --> 00:13:44,160
And then what do you do in the 
patients who still have no CMR, 

223
00:13:44,160 --> 00:13:46,760
so either the score four or 
five? 

224
00:13:46,800 --> 00:13:51,880
So we can create as you said 
delta SUV here to be sure that 

225
00:13:51,920 --> 00:13:57,240
we are really in not a good 
response and then we biopsy, we 

226
00:13:57,240 --> 00:14:01,480
try to biopsy the patients and 
we go to second line if we are 

227
00:14:01,480 --> 00:14:04,240
not in. 
Complete response. 

228
00:14:04,240 --> 00:14:06,200
Yeah. 
So you wouldn't go for radiation

229
00:14:06,360 --> 00:14:10,680
in those patients? 
We prefer depending on how is 

230
00:14:10,680 --> 00:14:14,280
the hazardous disease if you 
have minimal hazardous disease 

231
00:14:14,800 --> 00:14:20,800
with many I mean a small sites 
still involved and if 

232
00:14:20,800 --> 00:14:25,400
hyperfixation we may eventually 
propose a radiation therapy, but

233
00:14:25,600 --> 00:14:29,000
if we have no chemo sensitivity,
we will move to. 

234
00:14:30,840 --> 00:14:32,840
Yeah, I agree. 
And I think in this in this 

235
00:14:32,840 --> 00:14:38,040
study that I'll study, they also
showed that if you irradiate 

236
00:14:38,040 --> 00:14:41,640
this DOFIO score 4 cases and 
there's also a very good 

237
00:14:41,640 --> 00:14:44,320
response. 
But another strategy is just to 

238
00:14:44,320 --> 00:14:47,600
wait and repeat the PET scan. 
Exactly this, yeah. 

239
00:14:47,840 --> 00:14:49,840
Yeah, I think we've covered the 
first line. 

240
00:14:49,840 --> 00:14:53,840
And then we will shortly cover 
the second line that we had 

241
00:14:54,200 --> 00:14:57,480
really world that change 
completely with the gardice 

242
00:14:57,480 --> 00:14:59,440
cells. 
So Gardice cells now are in 

243
00:14:59,440 --> 00:15:02,480
second line with laser cell and 
axis cell. 

244
00:15:02,640 --> 00:15:08,200
And then in the accommodation we
propose axis cell, laser cell in

245
00:15:08,200 --> 00:15:11,720
second line for patients 
eligible to CARTES cells and 

246
00:15:11,720 --> 00:15:15,920
then for the patient that are 
not eligible for Cartes cells 

247
00:15:15,960 --> 00:15:19,600
and collapsing. 
So Cartes cells are for patients

248
00:15:20,080 --> 00:15:24,520
in the collapse and refractory 
patients collapse within the 

249
00:15:24,520 --> 00:15:27,880
first year and then for the 
patients that are not eligible 

250
00:15:27,880 --> 00:15:32,680
to for cartesis glaufygmarks or 
if you're collapsing really 

251
00:15:32,680 --> 00:15:35,480
late, you may eventually 
challenge the patients with 

252
00:15:35,480 --> 00:15:40,080
chemotherapy again and high dose
therapy plus orthologous 

253
00:15:40,280 --> 00:15:44,080
symptoms transportations. 
So the choice for this online is

254
00:15:44,080 --> 00:15:50,040
really depending on the time of 
collapse and the sense of how 

255
00:15:50,040 --> 00:15:55,000
refractory the disease is 
regarding chemotherapy. 

256
00:15:55,240 --> 00:15:57,200
Yeah. 
So in the in different countries

257
00:15:57,200 --> 00:16:00,760
this is weighed a little bit 
differently by also by the HCA 

258
00:16:00,960 --> 00:16:02,760
bodies. 
And for example in the 

259
00:16:02,760 --> 00:16:06,480
Netherlands, the patients in the
second line who are refractory 

260
00:16:06,480 --> 00:16:10,720
or who have early relapse should
be transplants eligible to 

261
00:16:10,800 --> 00:16:13,920
receive CAR T, which I think is 
a little strange because they're

262
00:16:13,920 --> 00:16:15,880
not getting high dose 
chemotherapy. 

263
00:16:15,880 --> 00:16:18,920
So they should be eligible for 
car DI think and not for stem 

264
00:16:18,920 --> 00:16:22,440
cell transplant. 
But yeah, hopefully there will 

265
00:16:22,440 --> 00:16:27,320
be the results of the daily two 
study and we can re discuss this

266
00:16:27,320 --> 00:16:31,240
also with with our healthcare 
institute in France. 

267
00:16:31,880 --> 00:16:33,200
It's not a problem. 
You can. 

268
00:16:33,280 --> 00:16:37,920
Yes, we can effectively use this
strategy for how the patients in

269
00:16:38,120 --> 00:16:41,360
early relapse. 
And then the Sol line that is 

270
00:16:41,560 --> 00:16:45,040
really improving with the 
bispecific antibodies, anti 

271
00:16:45,040 --> 00:16:50,200
CD20, anti CD3 with two 
antibodies available in Europe 

272
00:16:50,200 --> 00:16:54,960
and almost all over the world 
with glofetamab and apreitamabs 

273
00:16:54,960 --> 00:16:59,680
of both drugs that are changing.
Also the result in third line 

274
00:16:59,680 --> 00:17:03,480
for patients with refractory 
disease after two prior lines. 

275
00:17:03,520 --> 00:17:05,319
Yeah. 
I think in this context, it's 

276
00:17:05,319 --> 00:17:09,319
interesting the effort which was
done by Florence Prusa together 

277
00:17:09,319 --> 00:17:12,040
with the guidelines. 
We also actually published their

278
00:17:12,040 --> 00:17:16,880
perspective paper in Hemisphere,
which was led by Florence. 

279
00:17:16,880 --> 00:17:20,079
Actually looking at the 
availability of all those new 

280
00:17:20,079 --> 00:17:24,000
drugs in Europe. 
She has shown some, I think more

281
00:17:24,000 --> 00:17:27,359
shocking results about clinical 
trial availability, which is all

282
00:17:27,400 --> 00:17:30,160
very different between a 
different European country, but 

283
00:17:30,160 --> 00:17:34,720
also to access in terms of 
reimbursement to these new drugs

284
00:17:35,000 --> 00:17:37,920
because there are many countries
including ours where for 

285
00:17:37,920 --> 00:17:40,800
example, by specifics are not 
yet reimbursed. 

286
00:17:41,160 --> 00:17:43,760
So we're seeing a completely 
different picture. 

287
00:17:44,080 --> 00:17:46,360
Yeah, across, even across 
Europe, yeah. 

288
00:17:47,240 --> 00:17:51,320
