Thank you, Renee. Slide 15 provides an overview of our robust diversified pipeline that includes neuroscience and oncology programs across all phases of development. Consistent with our mission and strategy, these programs are focused on advancing the treatment of serious diseases for which there are limited or no options. Moving to Slide 16. This is an exciting time for our organization as we approach multiple catalysts across the pipeline. We now expect up to 5 late-stage data readouts through 2024, with all 5 addressing areas of significant unmet need. Starting with neuroscience, recruitment in our Phase III trial of Epidiolex in Japan is progressing well, and we now expect top line data in the second half of 2024. We are pleased to announce that we have completed enrollment in our ongoing Phase II trial of JZP-150 and PTSD. Based on timing of the last patient last visit, we are updating the anticipated timing of our top line data readout to January 2024. We also have ongoing trials for suvecaltamide, or JZP-385, in both essential tremor and Parkinson's disease tremor with top line data from the ET trial expected in the first half of 2024. If results are positive, we believe this trial could serve as part of a pivotal package. In addition, we anticipate initial proof-of-concept in healthy volunteers later this year for JZP-441, our Orexin 2 receptor agonist. Moving to oncology and Zanidatamab. We expect to report top line data from the ongoing Phase III frontline gastroesophageal adenocarcinoma trial next year. Later in the call, I'll provide an overview of our regulatory strategy for Zanidatamab, including an update on BTC. As Renee just mentioned, top line progression-free survival data in Zepzelca in combination with Tecentriq as first-line maintenance therapy for extensive stage small cell lung cancer is expected at the end of 2024 or early 2025. I'll now discuss some of our key programs in detail. Starting on Slide 17, with Zanidatamab, our highest priority pipeline asset. Given its potential across multiple HER2-positive tumor types, we are expanding and accelerating our development plans for this exciting molecule. Zanidatamab is a novel bispecific antibody that can simultaneously bind 2 nonoverlapping epitopes of HER2, known as biparatopic binding. This unique design results in multiple mechanisms of action, including dual HER2 signal blockade, receptor clustering on the cancer cell surface, leading to internalization by a biparatopic binding and potent immune activation, including antibody-dependent cellular cytotoxicity, antibody-dependent cellular phagocytosis and complement-dependent cytotoxicity, leading to encouraging antitumor activity in patients. Additionally, Zanidatamab can prevent HER2 from combining with other HER2 proteins and with ERBB receptor family members like HER3, which can further block growth signaling. Zanidatamab has shown compelling activity across a broad range of HER2-expressing tumors. And we presented promising efficacy and early survival data at ASCO in BTC and ASCO GI and GEA earlier this year. Most recently, BeiGene, which has development rights in some Asia Pacific markets outside of Japan, reported results at this year's ESMO meeting from a Phase II trial of Zanidatamab in combination with chemotherapy, atezolizumab, BeiGene's anti-PD-1 antibody in first-line gastric and gastroesophageal junction cancers. Data included an overall response rate of 76%, with a median duration of response of 22.8 months and a median progression-free survival of 16.7 months at the time of the cut-off. These data, along with our own GEA program, are building a body of evidence supporting the potential of Zanidatamab in treating first-line GEA. Based on compelling Phase II data, we plan to initiate a rolling BLA submission this year for accelerated approval of Zanidatamab for second-line treatment of biliary tract cancer. We expect to complete the submission in the first half of 2024 and anticipate that our confirmatory trial in first-line BTC will be open and enrolling patients prior to the completion of the rolling BLA submission. Turning to Slide 18. BTC and GEA are the first of multiple indications we plan to pursue for Zanidatamab. We believe Zanidatamab has the potential to raise the standard of care for some of the most difficult-to-treat HER2-expressing cancers, including breast cancer, where we see a significant potential to help patients in both early and late-stage disease. We are executing a comprehensive development plan and are excited about delivering this innovative therapy to patients. If approved, we expect to initially enter the market in second-line BTC where physicians would gain important experience with Zanidatamab. Following BTC, we expect to have a path to approval in first-line GEA with a supplemental BLA submission, which provides a more streamlined approval process compared to a full BLA. We strongly believe that a substantial opportunity remains to address the unmet patient need in first-line GEA, including in the HER2-positive PD-L1 negative patient population where the care remains trastuzumab plus chemotherapy. For patients who are PD-L1 positive, we believe that Zanidatamab has the potential to be the HER2-targeted treatment of choice, while also combining with a PD-1 inhibitor in order to treat those patients with GEA whose tumors expressed PD-L1. There also makes an opportunity to move into earlier stages of GEA where we see the potential to help those patients in the neoadjuvant and adjuvant settings. GEA represents a significantly larger patient opportunity compared to BTC. And a prior approval in BTC may accelerate adoption into GEA treatment time lines and protocols. We look forward to data from the ongoing pivotal Phase III GEA trial expected in 2024, which may support U.S. and global regulatory submissions. Breast cancer also represents a considerable opportunity, supported by promising early data for Zanidatamab as monotherapy in multiple combinations and across stages of disease and lines of therapy. Based on the efficacy and safety seen in studies to date, we believe Zanidatamab is well suited for early-stage disease including potential use as neoadjuvant and adjuvant therapy. Zanidatamab has also shown promise in HER2-positive and hormone receptor positive breast cancer as part of a novel combination. Based on these encouraging signs of activity, we have ongoing trials in neoadjuvant breast cancer, including an arm in the I-SPY platform trial, which is studying Zanidatamab for the neoadjuvant treatment for locally-advanced breast cancer. We are also evaluating the opportunity to expand into both combination regimens and later lines of therapy in HER2-positive and HER2 HR-positive breast cancer. Finally, we are also evaluating Zanidatamab in multiple early phase trials in other tumor types, where a few HER2-targeted treatment options are available. We are impressed with the strength of data and clinical activity Zanidatamab has shown across a diverse set of HER2-expressing indications such as colorectal cancer, non-small cell lung cancer and multiple other cancers where there continues to be a need for safe and effective targeted treatment options for patients. In summary, committed to rapidly advancing and expanding our development program for a molecule that has the potential to transform the current standard of care in multiple HER2-expressing cancers. Turning to Slide 19, JZP-150 is our novel, highly selective fatty acid amide hydrolase, or FAAH inhibitor. We are developing JZP-150 as a once-daily oral medication with the potential to impact the pathophysiology and symptoms of PTSD. By addressing the underlying cause of PTSD, impairment of fear extinction and its consolidation, JZP-150 has the potential to improve patients' associated symptoms such as anxiety, insomnia and nightmares. Preclinical and early clinical data showed activity on fear extinction and stress response. JZP-150 has a novel and promising mechanism of action, providing irreversible inhibition of FAAH, which we believe may have advantages over reversible FAAH inhibitors in development, and we anticipate top line data readout in January 2024. On Slide 20, I'll highlight JZP-441, a potent highly selective orexin-2 receptor agonist designed to activate and restore impaired orexin signal. Through this mechanism of action, JZP-441 has the potential to exert pronounced weight-promoting effects in people with sleep disorders. Orexins are excitatory neuropeptides that play an important role in the regulation of sleep and wakefulness. Patients with type 1 narcolepsy have a loss of orexin-producing neurons with impaired orexin signaling. And clinically, these patients often present with chronic disabling symptoms that significantly impact patients' ability to function normally during the day. Slide 21 illustrates the design of our Phase I program, evaluating safety, tolerability, pharmacokinetics and pharmacodynamics of JZP-441 in healthy volunteers. Our single ascending dose study is being conducted in sleep-deprived healthy volunteers and includes an evaluation of the weight-promoting effects of JZP-441 using the maintenance of wakefulness test, or MWT. This is a recognized disease model that historically has translated to patient efficacy. We also have an ongoing study evaluating multiple sending daytime doses in healthy volunteers intended to provide safety of chronic dosing in support of a multiple dose study in patients. Importantly, we have structured the program to maximize our learnings at this stage, including identifying appropriate dose ranges, which we believe will accelerate later development in patients. We're excited about the potential of JZP-441 and look forward to updating you on our progress later this year. Turning to Slide 22. Our team is advancing multiple preclinical compounds to a clinical stage development. JZP-815, a molecule that has emerged from our collaboration with RedX is one of our most recently initiated Phase I trials. JZP-815 is a highly selective potent pan-RAF inhibitor with a differentiated mechanism of action. It targets specific components of the mitogen-activated protein-kinase pathway that are known oncogenic drivers, active against multiple ARAF, BRAF and CRAF mutants and a spectrum of BRAF fusions. Activity against ARAF mutants may be an important point of differentiation as recent data suggests the importance of ARAF in the context of mutant RAS activation. JZP-815 also potently inhibits both monomer and dimer driven RAF signaling and prevents paradoxical pathway activation induced by BRAF selective inhibition. Slide 23 illustrates the design of the ongoing JZP-815 Phase I trial, evaluating the safety, dosing, pharmacokinetics, pharmacodynamics and initial antitumor activity of JZP-815 in participants with advanced or metastatic solid tumors harboring mutations in the MAP kinase pathway. It consists of 2 parts. Part A will characterize the safety and tolerability of JZP-815, determining a maximum tolerated dose and PK profile and determine a recommended Phase II dose to be further investigated and the expansion phase or Part B. Part B will investigate the antitumor activity at the recommended Phase II dose in various tumor types based on mutation status. Overall, our R&D team has been advancing multiple programs from our neuroscience and oncology pipeline, and we have multiple upcoming catalysts and near-term data readouts. Now I will turn the call over to Bruce for a financial update. Bruce?
