Right. Thanks a lot for the question, Chad. That’s a good one to spend some time on. So, OGX-427 and custirsen are different in a number of ways. The first and foremost is, they are targeting different molecular targets. And they do operate by slightly different mechanisms, although they do operate at their basic level as chaperone molecules. Their clients are different and there are some similarities, if you kind of get into the depth of the mechanism of action, which we don’t have to go into today’s call. But where we get into the selection of potential indications is we will always generally follow the data that is there. So, to the extent that we know the expression profile in humans for these various targets in the context of the development or treatment resistance that will certainly guide our thinking. Then we turn to preclinical data and look after each strengths of the evidence that is there for each one of the product candidates. Then we get into some more strategic discussions. For example, what is the landscape looking like what are the opportunities that way. In the case of lung cancer, I think you had alluded to the differences in lung cancer for the two programs. We’ve elected to go forward with OGX-427 and the frontline setting with pemetrexed. Whereas with custirsen and with docetaxel and both of those are data driven. 427 is data with pemetrexed, we see that is an emerging trend towards treatment for frontline disease. In the case of custirsen, we had obviously a lot of data for custirsen with docetaxel and most notably obviously the evidence that we had for prostate cancer that took us into the Phase 3, but we got a good safety base. So, we could probably also have generated data with custirsen with pemetrexed, but that data was not yet in house. So, some of that background is giving us the direction. And then as we think to the forward plans, we take an overview generally of the, what we think drugs into development might look like. The opportunities for not only executing successful Phase 2 and Phase 3 strategies, but also what the landscape may shift to on the commercial front. And that lend us to an interesting discussion for things like bladder cancer. In the case of bladder cancer, unfortunately for these patients, we have not seen advancements for new therapies for decades. And so when we look at that landscape, we say okay, we’ve got nice expression data, that preclinical data is supportive, and there is a market, a true market need where we don’t see our landscape is going to shift for us if we direct that way. Because it’s an obviously it’s history has now been well established for in the late phases of clinical development in both prostate and lung cancer and while we continue to do pre-clinical work, we are really focusing on the getting the drug across the line with respect to approval at this point. So, hopefully that gives you a pretty good overlay of kind of how we walk through the different opportunities if we see for the drugs there are fairly deepen and broad opportunities for both, where we could go into various solid tumors probably liquids as well. And then there is a basically an array of data sets and opportunities that we evaluate as we choose the indications.
