Thanks Mark. Now, I will provide a commercial update starting with BYETTA and then moving on to SYMLIN. BYETTA; is the first and only FDA approved incretin mimetic, a new class of drugs that mimics the action of the human hormone glucagon-like peptide-1. We have marketed BYETTA for more than three years and has been used by approximately 1 million patients. Importantly, BYETTA is the only medicine currently available that addresses the significant unmet need for a Type 2 diabetes treatment that achieves powerful, sustained glucose control with weight loss and a favorable safety profile. As I stated earlier BYETTA prescriptions are resilient in the face of significant environmental challenges. In the third quarter, we saw modest decrease in BYETTA prescriptions compared with second quarter which we believe is mainly attributable to the FDA update. Moving forward we expect sales to stabilize and then grow over time as doctors and patients better understand the facts about BYETTA and are able to better understand the benefit risk profile of the medicine. Today, I am going to report on the sales progress we are seeing as a result of the key market accelerators introduced last quarter. Our enhanced marketing approach and more closely aligned sales organization. I will also detail how these initiatives enabled our response to the FDA update. We believe these factors will drive BYETTA sales overtime and ensure we can effectively launch exenatide once weekly when approved. First, let's take a minute and discuss our response to the FDA update in August. As you know in mid-August the FDA issued an update to a prior alert for BYETTA regarding absurd cases of pancreatitis. To address the FDA alert with our customers, our field sales and medical teams rapidly educated the healthcare community about what the FDA's update meant. In fact, Amylin and Lilly changed together re-prescribed this accounting for three quarters of BYETTA prescriptions in just two weeks. Customers told us they appreciated the education and information which enabled them to make more informed decisions about patient care. We have since seen a large drop off in questions and concerns and our sales teams have returned to our core BYETTA messages. Those are that BYETTA continues to exhibit a robust benefit risk profile to patients with Type 2 diabetes and meet the large unmet need in diabetes management offering powerful and sustained A1C reductions with weight loss, improved list of parameters, decreased blood pressure and a low risk of hypoglycemia. I'd now like to highlight what we believe will accelerate the market for BYETTA and the class. In the third quarter, we saw continued progress with the market accelerators for BYETTA and GLP-I class that were present at the American Diabetes Association in June, where scientific presentations and conversations among the medical community focused on shifts that are needed in the treatment of Type 2 diabetes. The potential of the class and the benefits of BYETTA. A study examining the triple combination therapy of metformin, thiazolidinedione and exenatide as early initiation therapy to address known pathophysiologic defects in Type 2 diabetes patients as advocated by Dr. Ralph DeFronzo in the influential Banting Lecture at ADA is now underway. Based on the findings expected in 2010, this study has the potential to change the way diabetes is treated in it's earlier stages and importantly establish a unique position for exenatide in the treatment paradigm. At the associate, the European Association for the study of diabetes meeting in September, we presented the first head-to-head study comparing BYETTA and Sitigliptin a, DPP-4 inhibitor. There has been some confusion in the marketplace about the mechanisms of action between BYETTA and Sitigliptin and data from this study show the clear difference in the therapeutic actions. Patients on BYETTA experience significantly lower post meal glucose levels, improved measures of beta cell function and decreased food intake. As the medical community increasingly recognizes the potential of GLP-1 class, a medicine such as BYETTA which provides powerful sustained glucose control with weight loss and other benefits is uniquely poised to growth. In the third quarter we benefited from the refined sales and marketing initiatives that were fully implemented on July 1st to help us better communicate with doctors and patients. As a result of the expanded and better aligned Amylin and Lilly sales force we have seen an improvement in key performance indicators including increased share of voice, call time with physicians and cold dialogue. Additional indicators reflect the expanded market and patient support programs for the primary care market is having a positive effect. These programs are designed to better support BYETTA patients, new starts and improved long-term patient adherence. Further, the targeted access to education program for primary care physicians which underscores to more than 85%access to BYETTA across commercial managed care providers is in place. The results of the market accelerators and our enhanced marketing and sales efforts will be realized over the coming months towards growing BYETTA sales. We will continue to watch three key areas to determine we are on the right track towards increased prescriptions. One; an increased understanding of the importance of treating both A1C and weight in the treatment of Type 2 diabetes. Two, increased recall of BYETTA's core messages and three, increased new patient starts on BYETTA. Now, let's move on to SYMLIN. A synthetic analog of human Amylin and naturally occurring hormone that is made in the beta cells of the pancreas, the same cells that make insulin. SYMLIN; is the first and only Amylin mimetic, it's key benefits are that it provides mealtime glucose control and weight loss to patients who use mealtime insulin. In light of the strategic shift to focus more commercial efforts on BYETTA during the quarter, SYMLIN performed well, with a modest reduction in revenue to $21.5 million. As a result of our field force retaining to core BYETTA messages in customer interactions, we have also retained our focus to SYMLIN core messages, which will aid our efforts in growing the SYMLIN brand going forward. I'd now like to provide an update on regulatory discussions and development programs. At this time, we are in discussion with the FDA on label updates for BYETTA including the monotherapy indication, revision of safety language, data on exenatide use in patients between the ages of 12 and 16. Concomitant use with oral contraceptives and conversion of the package insert to the recently mandated physician labeling roll format referred to as PLR format. The key goal of both the FDA and Amylin is to ensure labeling provides adequate information for prescribers so they are able to prescribe medicines with full knowledge of the medicines benefit risk profile. We anticipate finalizing these by the label changes by the end of 2008. As a reminder we submitted our regulatory application for use of BYETTA as monotheraphy in the first quarter of 2008. Though the FDA has a heavy work load, and there are internal resource constraints of the agency, we are having ongoing conversations and anticipate a regulatory decision by the end of the year. When approved healthcare professionals will have the freedom to expand BYETTA usage along with treatment continuum as either standalone or combination therapy. A monotherapy indication will also allow even better pay of coverage in some plants thereby increasing patient access to BYETTA. We also continue to investigate in epidemiologic studies regarding adverse events associated with diabetes medicines. These studies provide insight into the safety profile for these medications within large sub sects of the population wherein base line characteristics are known. Now moving along I will share with you the latest developments regarding exenatide once weekly the next planned medicine in our pipeline. This product candidate is poised to become the first once weekly therapy to treat Type 2 diabetes with unprecedented dual efficacy defined as powerful glucose control and sustained weight loss. This is durable control that is offered in just one dose per week and provides improved tolerability with breakthrough convenience. As a reminder in the second quarter we had our pre-NDA meeting with the FDA to discuss the open items for our regulatory submission. Following these and subsequent discussions we continue to believe that the DURATION 1 study we reported last year provides the necessary safety and efficacy data for a submission and continue to plan on submitting an NDA before the end of the first half of 2009. During our pre-NDA meeting, we received more clarity on our strategy for showing comparability between the material manufactured at our facility in Ohio and the intermediate scale material used in the clinical studies to-date. We continue to execute this strategy, and we have now shared data from our in vitro-in vivo correlation or IVIVC studies with the FDA. This data is currently under review. As we've said in the past, this is a data driven process and until the FDA determines that this data is sufficient to show comparability we are reiterating our previous guidance on timing of a submission. We also have made great progress by finalizing the commercial scale manufacturing process at our Ohio facility. Indeed, we have already produced and shipped commercial scale material which has been used in ongoing clinical trial since the third quarter. This includes use of commercial scale material in our second path to demonstrate comparability to cross over patients from the extension of DURATION-1. The third path, we previously discussed to demonstrate comparability is a new bleaching study which would likely include both pharmacokinetic and clinical endpoints, if needed the design of the study will be finalized following input and guidance from the agency. Now, as you understand there are specifics of our interactions with the FDA that we are not able to share with you at this time. This is consistent ensuring that we meet the requirements of the agency. We will not speculate on potential FDA action regarding the data dependent nature of our regulatory path going forward. Moving on now to clinical data, DURATION-1 findings were presented at the American Diabetes Association and the European Association for the study of diabetes 2008 scientific meeting as well as published in the September 2008 issue of the Lansic [ph]. The data showed that continuous study state levels of exenatide provide durable glycemic control with weight loss. Additionally, improved glucose control was seen in patients switching after 30 weeks to exenatide once weekly, from exenatide taken twice a day. After 52 weeks, patients in both treatment groups experienced an average A1C decline of 2%. This level of A1C decline is unprecedented in a study of this type in patients with a mean baseline of A1C of 8.3% at entry. 74% of all patients achieved an endpoint A1C of 7% or less. Furthermore, patients in both treatment groups reported a sustained average weight loss of 9.5%. Based on our confidence from these data, we put in place an aggressive clinically relevant program that compares exenatide once weekly against competing products that demonstrates superiority. The objective of these studies is to support the launch and demonstrate the transformational nature of exenatide once weekly therapy. These trials are on track. In the third quarter, we completed enrollment of DURATION-2 which compares exenatide once weekly against the TZD and a DPP-4 inhibitor on a background of metformin therapy. We expect results from this study in the first half of 2009. We are currently enrolling DURATION-3 comparing exenatide once weekly against insulin glargine on a background of oral agent therapy and look forward to reporting results in mid-2009. DURATION-4, looking at exenatide as standalone therapy against either metformin, TZD or DPP-4 inhibitor we'll begin later this year. Additionally, given the positive effects on cardiovascular surrogate outcomes seen with exenatide, the encouraging data seen in the ACCORD trial and the current regulatory interest in cardiovascular outcomes, we have engaged a steering committee composed of outside experts to assist us in designing a robust cardiovascular outcomes trial. This design will be reviewed with the agency with plans to initiate patient enrollment in 2009. Clearly, we're actively positioning the exenatide franchise for near and long-term success and addressing the possible entrants of competitors in our classes. The powerful durable results from the exenatide trials, the three years of BYETTA's experience on the market and the stellar results from the DURATION-1 trial are compelling proof that exenatide is the best molecule in the class as a twice a day product now and as a once a week product in the future. Also I would note that given exenatide's potency we are continuing to study with our partners the potential for less frequent dosing regimen as well as non-invasive dosing form. Now, I will move on to describe our significant opportunities in obesity. We previously announced our commitment to pursue a medicine for obesity that is a combination of pramlintide, an analog of human amylin and metreleptin, an analog of human leptin. This commitment is based on impressive study results, 12.7% reduction in body weight over 24 weeks when pramlintide and metreleptin were used together. In the third quarter we completed enrollment of the Phase 2B study to evaluate different dosing combinations of pramlintide and metreleptin. This six months multi-arm study with approximately 600 patients enrolled will be completed in mid-2009. We believe this product candidate has the promise to meet the unmet medical need for a highly effective and safe weight loss therapy. Another exciting opportunity we have in our pipeline is our second generation Amylin mimetic AC2307 which we have now moved into Phase 2. We expect results from this study in the second half of 2009. AC2307 is an Amylin analog optimized for obesity with increased potency that offers the potential to enhance the efficacy and less frequent dosing. Lastly at the Obesity Society's annual scientific meeting in the beginning of October, we presented scientific data through 11 oral and poster presentation showcasing progress in our obesity pipeline. In addition to pramlintide metreleptin, and Ac2307, new findings were also presented on various pre-clinical program including a new white family mimetic and Amylin's peptide hybrid, or hybrid platform. And as Mark mentioned earlier, we are actively managing our R&D expenses. This includes pursuing options to offset the R&D expense associated with our obesity and early stage programs through potential partnerships and/or project financing. I'll add just a few more comments before we close. At Amylin, our goal is to be a sustainable, profitable company. In the coming months, we will further evolve our business model to be more flexible enabling us to maximize market opportunities and anticipate changes in our environment. To that end we will continue to increase our operational efficiency by looking at spending across our business to further focus spending on driving value and improving operating results. This will allow us to extend available cash and enable investments in growth program. At this time, we remain well positioned with a strong balance sheet and future financial flexibility which will enable us to execute our plans. In the near-term, I want to make it clear that this year we are focused on one; driving BYETTA and SYMLIN growth and two; completing the NDA submission for exenatide once weekly as soon as possible. Finally, to end; I would like to make some comments about the environment in which we operate. Today, we are experiencing the most challenging environment the biopharmaceutical industry has seen in decades, many would say ever. However, we believe that by bringing innovated medicines to patients, inventors and investors will be rewarded. Although the path to getting there maybe more challenging than in the past. We acknowledge this and we are making the necessary changes in our business to ensure shareholder value is maximized. With that, I will conclude the formal portion of today's call. And turn things back over to the operator for your questions. Question And Answer
