Just -- Rémy, a lot of the sort of key subjects have already been touched upon, but I'm just curious with the ongoing open-label extension. Are there any -- obviously, safety is the key sort of purpose of that. But I'm just curious, are there additional endpoints that are being measured that you think have some -- that have relevance and can really sort of enrich the dataset? And as you think about potentially needing to do other studies or just running studies to support the commercialization, are there things longer term that you would like to look at beyond typical -- that sort of typical sort of 12- to 16-week interval?
Rémy Luthringer: Doug, this is a very important question, very important point you're opening here. So clearly, I mean, yes, we are taking the box of long-term safety here, 1-year safety, but I think we discussed this already together. We are measuring efficacy as well. I mean -- and we continue to measure the PANSS, we continue to measure PSP. So we will have data for, I think, a significant number of patients at the end of the day for efficacy. So this is the first thing. And I think it will be important, hopefully, to demonstrate exactly what we have demonstrated in the Phase IIb, which means that after or beyond the double-blind phase of 12 weeks, I mean, patients continue to improve for negative symptoms and functioning. So this is obviously very important.
And I think it was an important aspect. We could discuss end of Phase II meeting with the FDA and, hopefully, we will also be able to discuss this at this meeting -- at this upcoming meeting because We have obviously followed this very carefully, and we are analyzing the data on a regular base to see where the things are going. But I think there is beyond the measures or the scales we're using, I think another aspect which is important, in addition to the safety aspect, is how many patients stayed in the study and how many patients are dropping out from the study and for which reasons? And one important aspect is to know how many patients are dropping out for relapses of positive symptoms because keep in mind here that I mean we have a monotherapy. We have not had all antipsychotics onboard.
And if we can demonstrate that over a period of 1 year, these patients are stable or even improving slightly on positive symptoms without the relapses, I think this is an important aspect as well. So a lot of data coming out from this extension. A lot of data are probably of interest to be discussed with the FDA. And what I can say is that, I mean, we are monitoring this continuously, and I think we are pointing towards the right direction.
