Thank you, Nichol. Good morning, and thank you all for joining us today. The year-to-date has been a dynamic time for Zevra and second quarter was quite productive for our team. We're very encouraged by the continued advancement of our rare disease pipeline programs towards multiple near-term clinical and regulatory milestones as well as by the progress that we are making to add in-house commercial capabilities needed to bring therapies to market directly. In addition, we continue to enhance our patient advocacy efforts, which include ongoing support of our early access programs for arimoclomol. Nichol, can you advance to the next slide, please? Our balance sheet remains strong, and we believe that we have made solid progress towards our strategic mission of delivering much-needed innovative therapy to people with rare diseases. An important update today is regarding our progress with the resubmission of the NDA for arimoclomol. Our product candidate for the treatment of Niemann-Pick Disease Type C or NPC. Earlier this month, we participated in a pre-submission meeting with the FDA, which focused on a preview of the complete package that we anticipate resubmitting for review. The meeting was productive and collaborative, and we gain valuable insight that we believe will help us to complete the package and give us our best chance for success. Our strategy for resubmission remains unchanged, and we are targeting resubmission by the end of this year. Regarding the development program for KP1077, our product candidate intended for the treatment of IH and narcolepsy. Our Phase II trial in IH is advancing with interim data expected by the end of this quarter. And we look forward to sharing that information as soon as it's available. Based on the pace of enrollment, top line results for the Phase II trial are expected to be available during the first half of 2024. In addition, the IND opening Phase I trial in our narcolepsy program has been initiated with enrollments now underway. We ended the second quarter with a solid financial position. As of June 30, 2023, cash, cash equivalents and investments were $87.4 million, which supports our forecasted operating cash runway into 2026. In addition, year-to-date net sales of AZSTARYS surpassed $25 million, triggering the first net sales milestone payment of $5 million, which was received after quarter end this month. Earning the first net sales milestone for the AZSTARYS program was an important milestone, providing momentum towards the possibility of earning a second net sales milestone in 2023. Our balance sheet continues to be a source of strength for our business, especially given the prevailing conditions of the capital markets. To round out recent events, just last week, we welcomed Tom Anderson to our Board of Directors. He is a highly accomplished industry veteran with both commercial and rare disease expertise, and in addition, is another important step within the ongoing Board refreshment plan. As we welcome Tom to our Board, we also want to express our gratitude to retiring board member, Matt Plooster. Matt has been with the company since before our initial public offering in April 2015, and his efforts to play a fundamental role in shaping our growth and advancing our mission. As a co-founder of Zevra, I want to extend my personal thanks to you, Matt, for your many years of service. As we move forward, the Board continues to be unified in its support of Zevra's rare disease strategy. Now more than ever, developing and commercializing therapies for rare diseases with the patient's first approach remains our mission as we work to build a best-in-class rare disease company. Since acquiring arimoclomol, our team has been engaged in multiple interactions with the FDA as we prepare an optimized NDA data package showcasing the safety and efficacy of arimoclomol. As I've mentioned previously, earlier this month, we held a pre-submission meeting with the FDA. We were encouraged by the productive and collaborative nature of the meeting, and we received important guidance from the agency that we will incorporate in the NDA package. As a result, we have refined our expectations that we will resubmit the full NDA to the FDA by the end of this year. As you may recall, the Complete Response Letter that Orphazyme received from the FDA in June of 2021 identified 3 main issues. The first issue was related to the validation and reliability of the NPCCSS instrument in measuring NPC disease progression. To address this issue, we plan to provide additional evidence to support the use of the scale as the primary instrument used in the efficacy trial. For example, the FDA confirmed that it is acceptable to conduct a new analysis of the original 5-domain NPCCSS by removing the cognition domain. The FDA also encouraged the company to conduct a qualitative study to assess the validity and robustness of the swallowing domain. The second issue that was related -- the second issue was related to the appropriateness of how to handle data affected by certain patient events and the method of primary endpoint analysis. To address this issue, we will be using an FDA preferred primary analysis together with additional supportive analyses. The third issue is related to the strength of the confirmatory evidence to support a single efficacy study. To address the third issue, we plan to provide additional data from multiple new nonclinical studies as well as data from the 4-year open-label extension of the Phase II/III clinical trial. The recent interaction with the FDA was constructive and provided us with additional information that we believe will further bolster the quality of our resubmission and ultimately support regulatory success for the benefit of the NPC community. In parallel with the preparation of the NDA resubmission, we are laying the groundwork for the potential commercial launch of arimoclomol in the U.S. is approved. With the goal of making this groundbreaking therapy accessible to patients as soon as possible. There are several strategic imperatives to ensure a successful arimoclomol launch. We are working to develop the NPC market through disease awareness with payers and prescribers. We believe patients can benefit from arimoclomol through key patient finding initiatives, such as genetic testing programs, early diagnosis tools such as newborn screening, and the development of other patient identification guidelines and resources. We also work to establish arimoclomol as a foundational treatment for NPC patients by continuing to engage key opinion leaders and educating treating physicians of its clinical profile. Our goal is to decrease the time from diagnosis to treatment through market access and create a best-in-class patient and caregiver experience through education, patient services and reimbursement assistance. We are developing a tailored patient services program to support insurance approvals, patient access and positive treatment experiences. And we will seek to continue our close collaboration with key stakeholders including key opinion leaders and patient advocates to establish Zevra as a trusted and committed partner within the NPC community. Throughout this journey, we are committed to working on inside people with NPC, their families and caregivers, advocates and medical community members. We are extremely grateful for everyone who continues to participate in trials FDA meetings and discussions and all of those who are supporting the development of treatments for NPC. Now let's turn our attention to KP1077. Our development program for rare sleep disorders. Beginning with idiopathic hypersomnia, or IH, we are pleased to report that our Phase II clinical trial evaluating KP1077 is progressing nicely. We are currently enrolling at over 30 sites across the U.S. As you may recall, the trial is a dose optimizing double-blind, placebo-controlled randomized-withdrawal study to evaluate the safety of KP1077 as well as potential efficacy endpoints such as sleepiness, brain fog and sleep inertia. Interim Phase II data that will be used to inform the design of the Phase III clinical trial are expected by the end of Q3 2023. Potential key differentiators include alignment of peak efficacy with patient need through dose optimized timing and expanded exposure range through unique pharmacokinetics. Based on the current pace of enrollment, we anticipate reporting top line data for the Phase II trial sometime during the first half of next year. In addition to the ongoing Phase II trial in IH, we expanded our KP1077 clinical program in April by opening an investigational new drug application, or IND, in narcolepsy. With the goal of exploring the possibility of adding an indication for narcolepsy and thereby expanding the potential that KP1077 could address multiple sleep disorders. The IND opening study, which is a Phase I clinical trial in healthy adults was initiated during the second quarter and enrollment has begun. As we move forward with programs in both IH and narcolepsy, we plan to evaluate the potential to initiate a Phase III trial in narcolepsy by seeking to leverage key data points from our IH program as well as leaning on the robust data generated for serdexmethylphenidate or SDX, as part of the AZSTARYS development program. As you may recall, SDX is a sole active pharmaceutical ingredient in KP1077. This strategic approach is aimed at enhancing our efficiency in developing KP1077 and bringing this potentially life-changing therapy to people in need across both indications. As you can see, we have been working diligently to drive progress in our regulatory and development programs. Now I'll hand the call over to LaDuane, who will provide an update on our financial results and outlook.
