Yeah, Brian. It's Norbert. So thanks for that question. Yeah, we presented data – 12 weeks data by the way. We couldn't do a longer study, because we didn't have the supporting talks, (31:28) talks done. That's done now, of course. And the data showed that there was a good reduction in liver fat as measured by MRI. There were also certain markers of fibrosis – biomarkers of fibrosis were down. Not all of them, but it looked then there was a dose response. So it was a very nicely behaved compound. And as John said in his prepared remarks, we will almost certainly start combination studies sometime next year. Now, you mentioned one side effect that we did see that was clearly drug-related was triglyceride elevations. Now two comments to that. First of all, out of the 16, the large majority, 12, occurred in patients that already started with high triglycerides of 250 or higher. Secondly, some of these triglyceride elevations were reduced to a lesser grade with continued dosing. So it seems to be an immediate effect. We think actually, by the way, mechanistic, it's a redistribution effect. You shut down lipid synthesis and then the triglycerides come by releasing VLDL from the liver. That's one hypothesis that we have. In the future, how we're going to manage this is, first of all, with statins or fish oil, and number two, by excluding those patients that have high triglycerides at baseline. We think this is manageable. As I said, either with con-meds or with choosing the patients carefully, and over time, the triglycerides may go down to normal levels. Again, we don't have data right now beyond 12 weeks. We will see that in the next study.
