This is Jeet Mukherjee on for Biren. Maybe 2 quick questions from me. First, if another confirmatory study is required, how quickly could you get that up and running? And the second question is perhaps maybe for Rémy. Your data, I think, showed that on the PANSS classic 7 item negative score, the 64-mg dose was statistically significant. So is there any analysis on your part -- on which items from the Marder scale didn't perform so well? And do you perhaps plan to use the classic scale as maybe a primary or perhaps co-primary endpoint for any subsequent Phase III that might be required?
Rémy Luthringer: Yes. So the first part I already addressed this one in one of the previous questions. So we are completely ready, I mean, to push the button if needed, I mean, for an additional study. So we have anticipated feasibilities. We have anticipated a study design. We have anticipated the infrastructure in terms of CRO, and how we will work with the CRO in order to run the study. So this is really ready-to-go afterwards. You have always the regulatory approval in the different countries and all these kind of things, but definitely as soon as we have the minutes, as soon as we know what we have to do, if we have to do it, I mean we are ready.
Coming to your second part, I mean, it's again a little bit linked to what I tried to explain based on the previous question. Obviously, we have analyzed item-by-item, question-by-question. We have analyzed our results coming out from the PANSS and particularly from the PANSS negative score according to Marder. And as I said, I mean, it's very clear that I mean if you're going with the items or the questions, which are mostly related to avolition, we know that the drug is extremely active compared to placebo. So this is just, if needed, a confirmation of what we have seen in the Phase IIb.
As I also mentioned, I mean, you can split the PANSS negative score according to Marder into experience and expression. And here again, I mean, we can really see that, I mean, the question/items, which are related to functional improvement or mostly related to functional improvement are, again, very significant with good effect sizes compared to placebo. So yes, there are a few items which are left, which are not showing as -- or a few questions, which are left, which are not showing the same statistical significance. But again, I think all what is related or what is connecting as a measurement via the PANSS of functional improvement is really showing a significant improvement.
And maybe a more general comment on all this. When you're going really to the [indiscernible] and to the current consensus of the scientific KOL medical community, I think everybody's stats is not in agreement that I mean, avolition is really an extremely important key driver of what happens in schizophrenia. These are patients, adolescents, they're good at school, and suddenly, they're losing the ability to really get engaged, to be interested in an activity, which is basically avolition. And it is very well demonstrated that, obviously, afterwards, I mean, these patients are presenting with other symptoms like anhedonia or alogia, whatever you want. But I mean this is really a consequence of avolition.
So I think this will be an interesting discussion with the FDA because I know that the FDA -- I mean, I'm speaking here about the psychotic division is interested in subscores to have drugs which are more specifically addressing some parts of a construct because negative symptoms is a construct basically. It's not a symptom, it's a construct of symptoms. And I'm really confident that we will have a very exciting and constructive discussion with the FDA around [indiscernible].
