Sure. So, I think physician education is always needed. No matter, how you look at any field in oncology and no matter how you look at any drug launch, it’s always harder to convert physicians to become prescribers than you just think. And so we are not going to underestimate the importance of physician education, and that’s a huge focus of our efforts. In fact our medical affairs, people who have already been out in the field talking about the ROS1 landscape, that creates awareness in general about ROS1 agents. It is a rare tumor, people don’t always see it a lot, so we are well aware of the importance of that. But I think that it’s pretty clear, though, that the way oncologists look at diseases is what’s treatable. And what’s really interesting about the lung cancer space is if you look at EGFR, ALK, RET, and ROS1, with the new precision oncology agents that are out there, these have suddenly become one of the most treatable cancers out there. Lung cancer used to be perceived as a death sentence. But with these specific mutation driven lung cancers and the agents that have been targeted against those mutations, these cancers have become eminently treatable. And that’s a really important point for physicians and patients to realize. And we think that our data demonstrates how treatable ROS1 cancer is with taletrectinib. 89% response rate, 46 months PFS, 44 months DOR, those are numbers that indicate that this is a highly treatable type of cancer and that we believe that knowing that will incentivize doctors to prescribe it and patients to seek it. And that’s our strategy. With regards to safety, we think our safety profile speaks for itself. Our drug discontinuation rate is low. In terms of treatment management, our most common adverse event is elevation of LFTs, liver function tests. And fortunately, oncologists have been using TKIs for decades. And the management of LFTs with TKIs is well known by oncologists, and we believe that we probably don’t need a lot of training in that area, because it’s been done with so many other agents. So, we think this is going to be a pretty easy drug to prescribe and a pretty easy drug for patients to take. But the most important thing of all, independent of any safety issue, we have always said that the greatest safety issue facing any patient is disease progression. And to address that, you want a drug that has a high response rate and a long durability of response, and we think taletrectinib offers that. So, that’s the platform upon which we are educating physicians and patients.
