Yes, so it’s an interesting data set. You might have to hand it to them for doing the study, the study of which, you know, was looking at a core inhibitor plus a new class time. So, the question is, could a core pose a new class time getting to a functional cure? And again, nobody knew the answer to that question. They looked at different time points over the course of the investigations, three months and six months, a year and so forth. And, you know, what I - the results that were produced in this in this initial study weren't particularly positive. You know, there could be a lot of different reasons there. It’s either new capacity or plus more time? You know, although they went for, you know, 12 to 18 months. So, it is a -- it's a good chunk of time. It's possible that the first generation, co-inhibitor wasn't, you know, take a nap. I think that's among the reasons why they're working on. ADP-514 arms are core inhibitor, is roughly ten times more potent than the one that you're referring to in that study. And then another possibility, of course, is the core of the new, plus a third agent that actually, you know, be the one in strategy to get you there., Just applying enough pressure on the virus and from different angles and from different stages of mechanistic intervention. And so, you know, all along we've been working on multiple different mechanisms. So we’d have something in addition to a new core inhibitor, and we're making pretty good progress on that front. So, I think earlier next year, we'll have more to sort of discussion around our progress on that front and then also on our strategy of coming up with a potential triple. I think for us, we're highly focused on all oral treatments. As you know, some of the - well, historically people have used interferon as an injectable. You know, we've got a new but it's sort of a poorly tolerated treatment that leads to very, very low cure rate. Other folks have been using some RNA approaches to add injectables to oral agents. And that's an interesting approach that some others are taking. We're highly focused and committed to. If we can come up with an all oral approach, we think in the end, having oral therapies, you know, potentially could be put together as a fixed dose combination and that could be disseminated to the millions of people, hundreds of millions of people globally that suffer from this infection that that would offer significant advantages overall. So highly focused on all oral agents and hopefully with the addition of a new [indiscernible].
