Thank you, Dan, and welcome everyone to KemPharm's fourth quarter and year-end 2016 financial and business update conference call. As Dan mentioned, we are providing a brief slide presentation to accompany today's remarks. From our founding in 2006, KemPharm has been and continues to be a product discovery and development company focused on building a portfolio of prodrug that are an improvement on currently approved drugs, and address unmet medical needs in large established markets. Our science seeks to improve the properties of existing drugs and our approaches to identify pharmaceuticals that address a large patient population where conversion to a prodrug that enabled better treatment outcomes, alleviate unwanted or unintended side-effects or enhance the marketability of the drug, especially those facing near-term patent expiration. Our value proposition offers an accelerated and derisk development timeline and composition of matter based patent protection on any new molecule we discover. This makes our prodrug technology a potentially compelling option for industry stars for new treatment options. Our internal focus is on developing prodrugs in the ADHD, CNS, and pain management spaces. However, any area where gaps and treatment combined with patent expiration really offers us an opportunity for prodrug technologies to improve drug performance and capture market share. One of the benefits of this approach is that it is a cost-effective development model. The time it takes to bring a new prodrug molecule from conception to NDA filing is roughly three to five years at a cost of between $20 million and $30 million, ultimately resulting in a potential new molecular entity with a significant product life. This development potential can be applied to a broad range of drugs, drug products in large markets where improvements and performance composition of matter based patent prediction along with development and cost efficiencies could enable the capture of significant value. As many of you already know, we accomplished this by using our Ligand Activated Therapy or LAT discovery platform. To create prodrugs by chemically attaching one or more molecules for what we refer to as ligands to an FDA approved parent drug. Our LAT discovery platform is simple yet elegant in design and is built on a 20-year plus foundation of research and scientific discovery that's been proven effective in numerous clinical and preclinical trials. Once we've identified the drug target, we use our LAT platform technology to create new molecular entity prodrugs by chemically attaching one or more molecules or ligand to the parent drug. So ligands are typically well understood. For instance, in the case of KP201/IR the ligand is benzoic acid, a widely used and extensively studied molecule which is known to be safe and essentially inert. When prodrugs are administered, targeted human metabolic process such as those in the GI tract separates the ligand from the prodrug and release the parent drug which can then exhert its therapeutic effect. KemPharm's ability to discover the unique parent drug ligand combination differentiates our prodrugs from other drug products in the market. Fundamentally, we create new molecules that can impart key advantages enabling the creation of potentially safer, more effective and therefore truly differentiated products. With our pipeline rapidly advancing in the clinic, we now have the opportunity to extend our LAT product discovery platform to additional drug targets and treatment indications. We intend to leverage our discovery expertise to create multiple opportunities to monetize our LAT platform. These opportunities include identifying new products for internal development which ultimately could be outlicensed or by discovering new prodrugs in partnership with other companies. While that remains our future, we now -- but now let's take a moment to review our recent accomplishments which I believe offer a validation of our prodrug strategy and showcases the underlying value of our company. The fourth quarter and early 2017 was the period of substantial accomplishment for KemPharm. We meet several key milestones which support the value of our development pipeline and our LAT prodrug platform. Specifically, during the fourth quarter we secured IND clearance and reported positive proof-of-concept clinical data for KP415. Our extended release, prodrug of methylphenidate for the treatment of ADHD, as well as received both IND clearance and fast-track status for KP201/IR, our single entity benzhydrocodone immediate release, abuse the prodrug for the treatment of acute pain. Additionally in January, a Phase 1 intranasal study of KP511, our investigational prodrug of hydromorphone for the treatment of pain demonstrated statistically significant pharmacokinetic and pharmacodynamics differences of abuse potential. Lastly, the formal dispute resolution request or FDRR filed on behalf of Apadaz continues to progress and we expect resolution prior to year-end. Over the next few slides, I will provide updates on most of these programs as well as anticipated development milestones and an outlook on the regulatory end-market landscape. KP415 is an extended released methylphenidate prodrug for the treatment of ADHD. We designed KP415 to address the unmet needs with currently marketed methylphenidate ADHD treatments which include onset, duration, and consistency of effect as well as the possibility of a lower abuse potential. As announced in mid-December, data from our Phase 1 proof-of-concept clinical trial indicated that KP415 demonstrated pharmacokinetic properties that produced earlier methylphenidate exposure followed by extended release of methylphenidate relative to the competitor Concerta. Although we still need to complete the planned pivotal studies with KP415, the data generated in this trial suggest that KP415 could offer ADHD patients an earlier onset of action with similar or better duration to Concerta. Together these properties are not available with any currently marketed or development stage ADHD products and could significantly differentiate KP415 in the market. During our December 14th conference call they discussed the KP415 studies, Dr. Scott Collins, Professor and Vice Chair for Research Strategy & Development; and the Director of the Duke University ADHD Program, noted that the data suggested that the prodrug design of KP415 could allow for once daily dosing with a potentially improved onset of action. As well the prodrug design of KP415 may also add significant benefits of a lower abuse potential which could be an important public health benefit. Dr. Collins comment align with the feedback from other thought leading clinicians who believe that early onset of action, durable therapy and once daily duration will be viewed as significant improvements in methylphenidate therapy for ADHD. If the pivotal studies of KP415 align with the generated data, we believe these properties can provide significant points of differentiation in comparison to currently approved products thereby enabling KemPharm with KP415 to potentially capitalize on key patient prescriber needs in the $13 billion plus ADHD markets. Given these factors, KP415 is one of the highest priority pipeline candidates and we believe our highest value product. Our strategy going forward is to continue the clinical development of KP415 with the next major phase being the initiation of the pivotal efficacy trial in the second half of 2017. Final data from this study is expected in the first quarter of 2018. In parallel, we plan to initiate several pharmacokinetic studies in 2017 with data expected throughout the course of the year. Studies will include urinary excretion study, disproportionality, food effect, steady state and pediatric pharmacokinetics among other studies. We also have an intra-phase 1 meeting plans or schedule for the FDA in the second quarter of this year; although this continues to point to us towards a potential NDA filing for KP415 in 2018. KP201/IR is our acetaminophen-free immediate release hydrocodone prodrug, designed for the treatment of acute pain. Like KP415 we achieved important milestones for KP201/IR during the fourth quarter including IND clearance to initiate human clinical trials and the granting of fast-track designation by the FDA. With these milestones, as well as the formulation work the eversion technology we remain in position to initiate the human abuse liability trial, KP201/IR in 2017 and anticipate reporting intranasal data from this study by the end of the year. We continue to target an NDA for this product in 2018 as well. As previously discussed, KP201/IR offers several potential market and patients advantages. It is being designed to be an abuse deterrent opioid that may offer comparable efficacy to Vicodin, Norco and Lortab, but with the potential safety advantage of having no additional acetaminophen. This is an important distinction as according to the FDA, overdoses of acetaminophen are the most common cause of drug related liver injury. In 2011, the FDA limited the amount of acetaminophen in prescription combination products, and required warnings to be added to the labels of all acetaminophen prescription products. Despite this, there currently are no approved immediate released hydrocodone related products without acetaminophen in The United States, potentially enabling KP201/IR to be the first to market, while also delivering clinically demonstrated abuse deterrent capabilities. As a reminder, our continuing investment in the abuse deterrent opioids is a strategic and interim decision process based on the Apadaz FDRR process, market and regulatory clarity as well as the change in political environment. Our third active clinical development program is KP511, our investigational prodrug of hydromorphone for the treatment of pain. As announced in January, we reported positive results from our Phase 1 intranasal study of KP511 which demonstrated statistically significant pharmacokinetic and pharmacodynamics differences of abuse potential. Data from the study indicated statistically significant reductions in peak and overall hydromorphone exposure with KP511 API versus hydromorphone API. The improved pharmacokinetics of KP511 resulted in meaningful statistically lower scores in the exploratory pharmacodynamics measures of drug liking, feeling high, overall liking and take drug again when compared to hydromorphone API. Furthermore, in a retrospected assessment of drug preference after the last treatment, a significant majority of subjects, 17 out of 26 prefer hydromorphone API over KP511 API, suggesting that KP511 may be less attractive for intranasal abuse. Several endpoints related intranasal irritation including nasal burning, need to blow nose, nasal discharge and facial pain were higher which really means more severe for KP511 versus hydromorphone API. All of these PK measures appear to align with FDA's current requirements to ADF labeling. Given the magnitude of the potential benefit that KP511 offered, we intend to develop both an extender release and an immediate release version of KP511. We anticipate filing NDAs for both of these products in 2019. In review, KemPharm's development pipeline continues to generate positive data showcasing the potential benefits that each asset offers in addressing important treatment opportunities and that we believe will lead to highly differentiated products that could enable us to capitalize unfavorable market dynamics. Looking ahead of the coming year, we anticipate reporting on several clinical and development milestones with KP415, KP201/IR and KP511 that should serve to greatly enhance the value of our product portfolio and the LAT prodrug platform. With that, I'd like to now hand the call over to our Chief Financial Officer, LaDuane Clifton, who will review our fourth quarter financials. LaDuane?
