Thank you, Lisa and good afternoon. Let me first take this opportunity to thank all of you for joining us on today's conference call. Today my prepared remarks are directed at three areas. First, I'll touch on the news we announced starting of this week about the FDA acceptance of NUPLAZID NDA with Priority Review and the work we're doing to prepare for the planned commercialization of NUPLAZID in the United States. Second, I'll discuss the important work we've conducted to date in our comprehensive life cycle planning project and our planned expansion of pimavanserin into other areas of significant unmet medical needs. And last I'll comment on our financial results for the third quarter. Following my review, Terry will lead a review of our pre commercial activities for NUPLAZID and then we'll open things up for questions. We've had a productive last couple of months. We submitted our NDA for NUPLAZID for Parkinson's disease psychosis or PDP in early September, we announced on Monday of this week that the FDA accepted the NUPLAZID NDA for filing and granted Priority Review with the PDUFA date of May 1, 2016. This Priority Review comes on top of NUPLAZID's breakthrough therapy designation in PDP in 2014. As a reminder Priority Review accelerates the review timeline from 10 months to six months from the date of acceptance of filing and is granted to drugs that may offer major advances in treatment or drugs that may provide a treatment where no adequate therapy exists. In NUPLAZID's case we believe it addresses both of these [structures], that is it potentially offers a major advance in treatment, as it would be the first and only drug approved for psychosis associated with Parkinson's disease. I understand that many of you may have questions about the NDA or our interactions with the FDA but I'd like to note that with the review underway there is really very little we can say about these topics. So, as I'm sure you'll understand we don’t intend to provide any specific updates or comments on our discussions and the interactions with the FDA during the NDA review process. With our PDUFA date set six months from now, I'd like to discuss the work we're doing to prepare for the planned commercial launch of NUPLAZID in the United States. We continue to build out our commercial team, we're now in the process of recruiting approximately 135 sales reps, we plan to bring the reps onboard around the time of NDA approval. In addition of the sales force, we've built a commercial team with extensive experience in launching major drugs. The team we have on staff today includes seasoned executes, regional sales managers, regional account managers, marketing and sales leaders and managed market experts. This [recruitment] is on plan as we establish key distribution channels and other important activities required for a successful launch. Terry will highlight these activities in more detail later on the call. In addition to the commercial build out we've hired a very experienced team of medical affairs personnel. This group is making valuable contributions today as we continue making important strides in educating the physician community about PDP through our disease awareness campaign. While our top priorities are taking FDA approval for NUPLAZID and successfully launching the drug in the United States, we also are conducting very important work in mapping out our multi-year plans to develop pimavanserin in indications beyond PDP. As we discussed on our last quarterly call in the second quarter we initiated a significant life cycle planning project to prioritize the indications we planned to pursue with pimavanserin. Given the unique and very attractive profile of pimavanserin together with the long list of potential indications we could pursue this is a substantial and a very important undertaking. Due to engagement with key thought leaders in the CNS space, a prominent pharmaceutical consulting firm and the dedicated efforts of a cross-functional internal team, we're laying the foundation for how we plan to develop pimavanserin in the years to come. On the second quarter call in August, I noted that we were midstream on this project. We are now in the later stages of this [workstream] and intend to complete the project around the end of the year. I'm very pleased with the results so far. As part of this life cycle management project we've taken a ground up approach to assessing the opportunities in each indication that we're considering including Alzheimer's and schizophrenia. Though the project is still ongoing we're far enough long in the process to discuss a few important findings including one new indication we've not previously discussed. In addition to our ongoing development of pimavanserin in Alzheimer's disease psychosis, we plan to develop pimavanserin in Alzheimer's disease agitation or AD agitation. We're elevating the priority of this new program and to plan to initiate a phase two study in AD agitation in the first half of 2016. Now, let me describe a few of the underpinnings of these plans. As you're aware Alzheimer's is one of the most devastating disorders of our time and will continue to grow as our population ages. Alzheimer's disease is a multi-dimensional disease associated with cognitive decline, psychotic symptoms and behavioral disturbances including agitation. Similar to psychosis agitation which comprises agitation and/or aggression can have a major impact on the quality of life of patients and caregivers and it's believed to accelerate cognitive decline. It's also a pre-curser to nursing home placement. Agitation presents earlier in the progression of Alzheimer's disease and psychosis and once present it tends to be recurrent and sustained. The unmet need in AD agitation is significant, it's believed that there are more than 5 million patients with Alzheimer's disease in the United States, about half of these patients have been formally diagnosed with Alzheimer's and of the around 2.5 million patients diagnosed with Alzheimer's disease it's estimated that about 40% to 50% exhibit agitation. Today there is no FDA approved therapy for AD agitation. With no approved therapy physicians often prescribe typical and atypical antipsychotics off label for patients with AD agitation. However as we know, studies have shown that these antipsychotics are associated with increased morbidity and mortality in elderly patients with dementia and carry significant side effect hurdles. Furthermore one more important study of the AD, Alzheimer's disease study has shown that atypical antipsychotics are associated with worsening cognitive function at a magnitude equivalent to one additional year of disease progression in an Alzheimer's patient. We believe pimavanserin is well positioned to fill this unmet need in AD agitation, through pre-clinical and clinical studies suggest that blockade of 5-HT2A receptor is associated with decreased agitation and aggression. We believe pimavanserin selective activity is the 5-HT2A receptor making for efficacy in AD agitation and in addition, the pimavanserin's favorable side effect profile observed today in treating elderly patients with PDP may make it an ideal therapy for AD agitation. We look forward to pursing AD agitation in the clinic, we're currently are in the planning stages of this phase II study and as I mentioned plan to initiate the study in the first half of 2016. We believe our AD agitation program also strongly complements our ongoing phase II program in Alzheimer's disease psychosis or ADP, agitation and psychosis are both major components of the broader range of behavioral disturbances in Alzheimer's disease. We continue to advance our phase II - 019 study with pimavanserin in ADP and as previously guided anticipate enrollment in the study to be completed in the first half of 2016 with top line data reading out in the second half of 2016. Let me now turn to our plans with pimavanserin and schizophrenia. We've generated a large body of work in schizophrenia, it's an area where pimavanserin has shown clinical utility and is high on our priority list. As you are aware schizophrenia is a vast market opportunity and a very complex disorder. It is multifaceted with multiple unmet needs. Today's drugs carry significant side effects and do not adequately address some very important symptoms of schizophrenia including negative symptoms. Schizophrenia is also an indication for which many drugs are approved and many of these approved drugs are generic. So, in addition to schizophrenia being a very complex medical disorder the commercial landscape overlays an additional facet of complexity. We previously discussed our plans to commit to monotherapy study in schizophrenia patients during the maintenance phase that is between acute psychotic episodes of the disorder. While we remain very interested in the maintenance part of schizophrenia, a couple of additional areas of interest within the schizophrenia umbrella have risen in priority. They too represent areas with large unmet medical needs. We are currently completing our assessment of these opportunities as part of our life cycle management planning projects. Until we finalize our development plans in schizophrenia we will not start the maintenance study that was previously scheduled to begin around the end of this year or early next year. Let me just pause and say we're taking a very disciplined and thorough approach in our life cycle management project and we want to be certain that we have a well-informed plan in pursuing the very best opportunities in this area. We expect to finalize our development plans in schizophrenia around the end of this year and look forward to sharing with you further information about this program. Also as part of our life cycle management planning project, we've decided not to pursue a separate sleep study with pimavanserin. We've concluded that a separate sleep study would not provide sufficient, additional information to the strong sleep data we already have generated with NUPLAZID in clinical studies. Now, turning to our plans in Europe, we plan to submit our NUPLAZID marketing authorization application or MAA to the EMA in the second quarter of 2016 as previously guided. Our life cycle planning project is of course part of our broader strategy to aggressively pursue the full utility of NUPLAZID or pimavanserin and a key underpinning of this plan is to continually grow and strengthen the organization including the addition of key people and resources. This year we've added important new team members both internally and externally. A natural extension of a growing company is the recognition that you also done departures during the process. As you'll see in a filing we'll make shortly, Roger Mills are EVP and Chief Medical Officer has recently left the company for personal reasons. We have a very strong team of both internal and external resources and have long had robust succession plans for all key positions. We wish Roger well and appreciate his contributions to ACADIA. In connection with today's discussion of the life cycle management project, I'd like to introduce two key additions that have been instrumental to our life cycle management project and our strengthening of ACADIA generally. One key addition to the executive team is Bob Mischler our Vice President of Business Development and Strategy. Bob has extensive experience in new product development in the pharmaceutical industry and he's a critical driver of the life cycle process internally. Another key resource for us on both the life cycle management project and in the development of NUPLAZID is Ed Harrigan who serves as a consultant to ACADIA. Many of you on the street may know Ed, for those of you who have not met him, Ed formally lead the CNS drug development efforts at Pfizer, he's then served as Pfizer's Global Head of Business Development and most recently was Pfizer's Global Head of Regulatory Affairs and Drug Safety. Both Bob and Ed will be available to answer questions during the Q&A session. Let me now touch briefly on our financial results, our financial results for the third quarter aligned with our strategy which as previously communicated is to build a leading U.S. specialty CNS franchise using pimavanserin as the foundation. Turning now to the numbers, total operating expenses for the third quarter of 2015 were $39 million. R&D expenses for the quarter increased to $18.7 million from $17.0 million for the comparable quarter of 2014. This was primarily due to increased personnel and related costs, including stock-based compensation expense associated with our expanded R&D organization. The increase in personnel and related costs was largely offset by pimavanserin manufacturing development costs incurred in the third quarter of 2014 that were not incurred in 2015. G&A expenses increased to $20.3 million for the third quarter from $8.1 million for the comparable quarter of 2014, this reflected our continuing investment and commercial preparations for the planned U.S. launch of NUPLAZID. And specifically costs incurred during the third quarter of 2015 associated with medical affairs, disease awareness education programs and market research activities. We also had increased costs related to the build out of our commercial organization and systems, including sales in managed markets. And lastly, G&A related stock-based compensation expense increased by $2.8 million for the third quarter of 2015 over the comparable quarter of 2014. Now I'll turn to our cash position, we ended the quarter with $240.7 million in cash and investments. We expect our cash used in operations to continue to increase in future periods as we execute on our current business plan as I described earlier on the call. Importantly, we believe our strong cash runway positions us to continue making the kinds of investments that we believe will leverage the full potential of pimavanserin. Under our current plan, we anticipate our cash resources will be sufficient to fund our operations at least into the second half of 2016. And with that, I will now turn the call over to Terry, who will discuss our commercial activities.
