Thanks, Stephanie, and thanks to everyone on the call for joining us this morning as we discuss a number of important developments in our business during the third quarter and through October. John and I are going to walk through some details on our remarks today and will then be joined by additional members of the Aquestive leadership team during the Q&A session afterward. The third quarter was an important and successful quarter in the evolution of Aquestive. We have, as previously committed, completed our proof-of-concept study for epinephrine, AQST-108, for the treatment of allergic reactions, including anaphylaxis, and have requested a pre-IND meeting with the FDA. We've continued to grow SYMPAZAN more than 50% since the end of the last quarter and successfully completed the FDA-requested crossover study of Libervant in patients against the reference listed rectal gel. Let's discuss in more detail each of these key areas of focus for the Company. First, let's talk about AQST-108. In late September, as promised, we completed the Phase I proof-of-concept clinical trial for AQST-108, our sublingual film formulation delivering systemic epinephrine. The proof-of-concept data demonstrated our ability to deliver systemic epinephrine via our PharmFilm formulation. Notably, we achieved similar ranges of mean values of Cmax and Tmax to that reported for injectables EpiPen and AUVI-Q. Last week, we submitted our request to the FDA for a pre-IND meeting. We are waiting for feedback from the agency regarding potential dates for this meeting to discuss the development pathway for AQST-108. At this juncture, we anticipate this meeting will be scheduled for the early part of 2020. The central focus of our company at this time is our CNS franchise. As you all know, we launched SYMPAZAN at the very end of last year. SYMPAZAN is a product we believe will ultimately generate $65 million of peak annual net sales. SYMPAZAN has a meaningful value proposition for caregivers of patients suffering from Lennox-Gastaut syndrome or LGS. SYMPAZAN also represents a significant step forward in establishing our commercial infrastructure and raising the profile for Aquestive's technology as we continue to drive toward an ultimate approval and launch of Libervant. We launched SYMPAZAN, whose prescribers overlap greater than 90% with potential prescribers of Libervant, late last year with the aim of raising the profile of our PharmFilm technology. SYMPAZAN was developed and launched as a commercial precursor and eventual complementary product in support of the Libervant opportunity. SYMPAZAN gave us the opportunity to build out and pressure-test our commercialization capabilities and processes prior to the commercial launch of Libervant. All of our commercialization efforts relating to SYMPAZAN provide an opportunity for direct conversations with health care practitioners, patients, caregivers, advocacy groups and others about the value of the PharmFilm technology that will be the basis for Libervant. On a sequential quarterly basis, we continue to be focused on the growth and further market penetration of SYMPAZAN. The latest monthly SYMPAZAN shipment volumes to retailers has grown over 50% since the end of the second quarter. The prescribing base also continues to grow, over 56% since the second quarter, with over 83% of prescribers writing multiple scripts and over 70% of the patients refilling their scripts. Additional contracts with payers and PBMs were signed since the second quarter, and we continue to expect to achieve our goal of having over 70% of lives covered by the end of the year. SYMPAZAN is a strategic -- is strategically accomplishing what was intended when we developed and launched the product last year. The work we do to continue to build the revenue stream and market penetration for SYMPAZAN will be an important foundation for the successful launch of Libervant expected in 2020. The Company's efforts are most sharply focused on bringing Libervant to market. Libervant represents a major contribution to patient care for the treatment of seizure clusters in patients with epilepsy and we believe will potentially contribute up to $200 million to $300 million in peak net revenues. Over 1 million patients in the U.S. have active, uncontrolled epilepsy and a need for rescue medication. Less than 10% of these patients are successfully treating their seizures with the current standard of care, a rectal gel application of diazepam. A medicine is only as good as its ability to be used by patients where they need it, when they need it and in a form they accept. As we announced previously, during the third quarter, we successfully completed the single-dose crossover study for Libervant. We believe that we've met the specific requirements for approval communicated to us by the FDA, and our product continues to prove that it has attributes lacking in all of the current or pending formulations of diazepam. As shown in the recently completed crossover study trial comparing Libervant with the rectal gel in patients, the peak blood concentration of diazepam following buccal film administration was comparable to that of diazepam rectal gel. Also, the performance of the film measured by peak concentrations was more consistent across weight categories compared to the performance of the rectal gel. Importantly, the data continued to show that there were no nonresponders to Libervant. The rectal gel, however, continued to show, as it has historically, low and nonresponders of 10% or more in our latest study. This is a critical milestone for our lead asset and puts us on a clear and straightforward path to completing the filing of our NDA for Libervant. We filed the CMC portion of the rolling New Drug Application submission with the FDA in September. We expect to file the clinical data portion around the end of November, which will mark the completion of our submission. Assuming a 10-month review cycle, we are anticipating receiving a PDUFA goal date around the end of the third quarter of 2020. We believe that Libervant will become the preferred rescue medication by patients and providers looking for an alternative, potentially superior and clinically differentiated treatment to manage and interrupt seizure clusters. This is based on strong data that shows the product can be quickly and safely applied, results in consistent therapeutic levels and comes in a form preferred by patients. Based on patient survey data, Libervant is preferred by 80-plus percent of patients when compared to nasal sprays. Once approved by the FDA, Libervant will be the only treatment option usable by and delivering a consistent, predictable dose to virtually all patients to whom it's prescribed. We plan on having a strong presence at the American Epilepsy Society Annual Meeting in Baltimore in early December. We have multiple poster presentations, and we're planning to hold an investor and analyst R&D event on December 9 that will feature a handful of key opinion leaders in the epilepsy field. Moreover, we're sponsoring a scientific exchange meeting at AES the morning of December 9th for clinicians and others to learn more about Libervant and the expanded clinical data set that we'll be showcasing at the meeting. We believe AES is one of the most important epilepsy conferences of the year. With the imminent filing of Libervant, we believe this is an important event for us to showcase our technology and product offerings. Finally, in line with our expectations, Exservan, our PharmFilm formulation of riluzole for ALS, continues to move toward a November 30 PDUFA date. As we've said previously, we're seeking to license the product outside the United States, and we've begun the process of identifying potential commercial partners in the U.S. as well. Looking ahead for the remainder of 2019 and into 2020, we are focused on advancing our proprietary products. We will continue to grow SYMPAZAN shipments and revenue while establishing strategic relationships for us in the epilepsy market in advance of a Libervant launch. And we expect to complete the NDA filing for Libervant around the end of November, as I said before, and continue the regulatory process through the early part of 2020. We look forward to continuing to update you as we make progress on these key deliverables during the remainder of the year and in the early part of 2020. I'll now turn the line over to John Maxwell, who'll provide specifics of our financial performance and outlook.
