Thanks Joe. We’ll take it in two parts. Co we did have an opportunity earlier in a quarter to go and sit down with our colleagues at AstraZeneca. And we were given a very comprehensive review of where the program stands, and it certainly includes the Phase 1 data that was generated, as well as the design and objectives of the current trial and really the future plans, all the way out to today’s three. This is a key program for them in their Metabolism and Endocrinology Group, that’s one of their lead programs. Beyond that, I am certainly not, the enthusiasm is quite high, obviously we are not allowed at liberty to discuss the details of it, but suffice it to say that they’ve got a very comprehensive program designed and ready to implement, from where we sit today to the Phase 3, decision point. So we are very very pleased with the program, and what they’re doing and committed to putting into it. Getting on to the second part, which is thinking about different mechanisms and we certainly in the last week, had a very nice vote from the FDA advisory panel on Arena’s product Lorcaserin, that’s a 5H2C agonist, designed for the treatment of obese patients, and on the their second panel round, go around they actually had, as I said a positive vote.. One thing that’s exiting to us about the program is the melanocortin-4 receptor and it’s attended signaling pathways play key role in regulating many many different signaling pathways that are involved in food and energy regulation. For examples, signals like leptin, ghrelin, search noted signals like 5-HTC receptors, impart signal into the hypothalamus and work through the MCR-4 signaling pathway to actually bring about their effects on reduction and weight loss. So we really do believe that we are sitting in a very key signaling junction pathway, than with in a very key signaling pathway, that’s involved in regulating food intake. So, when you think about things like 5-HTC receptor agonist, these are compounds that stimulate or activating large number signaling pathways, both in the central nervous system and peripheral, many of which have benefit and some of which don’t. So, as you can see part of that panel, was quite heavily involved in discussing the potential safety effects of that drug due to its non-abusive related signaling. So, we believe that really targeting the MCR-4 receptor directly which is what AZD-2820 does, really avoids a lot of that ancillary issues around non specific activation and puts you right where you want to be, direct activation of the key signaling pathway, patients taking it feel that the satiated but food intake weight loss.
