So Leone I mean, that's a great question. I mean, I think, some of the questions that you are asking also relates to the question that we did not respond to [indiscernible] initial question about comparison of our data to what it has been reported for the autologous cell therapy. One thing that I'll say is in multiple myeloma, as we all know, there is a lot of treatment options that are available. And frankly, patients remain on treatment for a long period of time because that's how some of the proteasome inhibitors, as well as image has been develop. One thing that we constantly hear from the physicians, that yes, that are certain options, but none of these treatments really provide what will be a cure. And also, all these patients will eventually progress. So, the existing therapy perspective, I mean, there are three major categories of drugs that have been used, proteasome inhibitor [indiscernible] immune-modulating drugs such as Revlimid. And then, the third one, CD38 monoclonal antibody therapy. Essentially the patient population that we are targeting are the ones who have already gone through those existing therapies. And this is where now BCMA target therapy, whether it be chimeric antigen receptor, or ADC, it's really fits in. I think the good thing about all the efforts that different companies are making is that at the end there will be more treatment options that physician and patients can use. And to some extent it will depend on the physician's comfort level, as well as preference. However, we definitely see a situation where different BCMA targeted therapy can potentially be sequenced. The data it's pretty still premature in many ways, but I think, we're beginning to see some cells maybe there are some differences in the response rate, however, so-called the progression-free survival this all seem to give a similar number. I think that’s the current early read of the data which obviously we’ll have to know more. So that’s the setting. And what we are coming with our BCMA targeted programs ALLO-715, I mean as an off-the-shelf therapy that can potentially give a deep response that’s durable, I think, we can position our product well in this space, once we complete the pivotal study. Hope this is sort of answering your question, but the nature of your question until all the dust settles is somewhat speculative at this point, but we have a clear position on how we want to put our product in this space.
