Yes. So the HRT1 study is -- and similarly, is a Phase I/II trial, evaluating our vaginal ring for hormone therapy. We have already completed a Phase I study, which I point out simply because the study that we've already completed is relevant to your question a couple of ways. So first of all, the study that's already been completed with HRT1 really already demonstrated the PK profile and importantly, demonstrated its potential to be effective in both the vaginal atrophy as well as the vasomotor symptoms of menopause because we looked at -- we know the therapeutic dose levels of those hormones. And so that has already been demonstrated. What we wanted to do in this study is give women an opportunity to actually use the product for 3 months in a row with a 28-day vaginal ring. So 3, she'll get to use it 3 different times, 3 different rings over the course of 3 months, and we are looking at the same 2 doses again. It's about 20 women. They are all postmenopausal. So again, these are women that are in menopause. And so similarly to what I talked about with the VVA1 study, we'll be looking at safety, usability, acceptability as well as symptom release data. So very similarly, we're asking them about their most bothersome symptoms of menopause before they come in and then we're going to ask them how they're doing, after 3 months of using the product. So again, not powered for efficacy, but will give us some nice signs. In terms of the site, we do a number of our Phase I studies in Australia, very cost effective, right, because of the Australian R&D cash rebate. And we actually have a few sites, and Australia is not huge. So we have a few sites that we work with across our studies in Australia, so it's the same sites. And as John mentioned in his comments, what we found quite interesting, and I think it says a lot about the product is women who had been in the prior Phase I asked the -- at the end of that study, said, "My gosh, can't we just keep using this? No, you can't. But they asked to be notified of any future study. So many of the participants in this study already had experience with the product because they were in the prior -- prior Phase I study. So we don't need to really add any additional sites. So at this point, we're following the subjects in the trial, and then we expect, as I mentioned, that top line data readout in the fourth quarter.
