Thank you, Mariann and thank you all for joining our call today. Today, Puma reported total revenue for the second quarter of 2023 of $54.6 million. Total revenue includes product revenue net, which consists entirely of NERLYNX sales, as well as royalties from our sub licensees. Product revenue net was $51.6 million in the second quarter of 2023, which represents increases as expected from $46.8 million reported in Q1 2023 and $51.3 million reported in Q2 2022. Product revenue for the second quarter of 2023 was impacted by approximately $1.5 million of inventory drawdown at our specialty pharmacies and specialty distributors. Royalty revenue was $3 million in the second quarter of 2023 compared to $6 million in Q1 2023 $8.2 million in Q22 2022. We reported 3022 bottles of NERLYNX sold in second quarter of 2023, an increase of 173 from the 2,849 bottles sold in Q1 of 2023. As I noted on last quarter's call, we estimate that inventory increased by about 164 bottles in Q4 2022 and then subsequently declined by about 236 bottles in Q1 of 2023. In Q2 2023, we estimate that inventory was further reduced by about 89 bottles. In Q2 2023, new prescriptions or NRx were down approximately 12.5% compared to Q1 2023 and total prescriptions were up approximately 0.4% compared to Q1 of 2023. Jeff will provide further details in his comments and slides. I will now provide a clinical review of the quarter. Then, Jeff Ludwig will add additional color on NERLYNX commercial activities, Maximon Nougues will follow with highlights of the key components of our financial statements for the second quarter of 2023. In our investor call in October 2022, we announced that we had in-licensed the anticancer drug alisertib from Takeda. In clinical trials to-date, alisertib has shown single-agent activity and activity in combination with other cancer drugs in the treatment of many different types of cancer, including hormone receptor-positive breast cancer, triple-negative breast cancer, small cell lung cancer and head and neck cancer. The drug has also shown previous clinical activity in clinical trials in peripheral T-cell lymphoma and non-Hodgkin lymphoma. Takeda's previous clinical development plan with alisertib was extensive. And due to this, there is a large well-characterized clinical safety database with over 1,300 patients who are treated across 22 company-sponsored trials. In terms of the prior experience in small cell lung cancer, as is shown on the slide, alisertib is -- was previously tested in a Phase 2 trial that was previously published in Lancet Oncology. In this trial, alisertib was tested as a single agent in several cohorts of patients with solid tumors. In the small cell lung cancer cohorts, the study design involved the administration of alisertib monotherapy to patients with small cell lung cancer who had previously received up to two prior cytotoxic regimens in the metastatic setting. Patients were administered alisertib monotherapy at a dose of 50 milligrams BID for seven days followed by a 14-day break. As you can see in the table on the right of the slide, in patients with chemotherapy sensitive disease, alisertib resulted in a response rate of 19% and a duration of response of 3.1 months. For the patients with chemotherapy refractory or chemotherapy-resistant disease, alisertib resulted in a response rate of 25% and a duration of response of 4.3 months. We note that the results in patients with chemotherapy-resistant disease compare favorably to results with recently approved drugs in chemotherapy-resistant small cell lung cancer. As you can see on the slide, you can see the waterfall plot for the patients treated in the trial with small cell lung cancer treated with alisertib monotherapy. On this slide, the light blue bars represent the chemotherapy-sensitive patients and the red bars represent the chemotherapy refractory or resistant relapsed patients. On this slide, you can see the adverse events in the trial. The AEs for alisertib are similar to what one would expect for a drug that targets the cell cycle. The main grade three or higher AEs in the trial were neutropenia, anemia, leukopenia and thrombocytopenia. Alisertib was also tested in a randomized, double-blind placebo-controlled Phase 2 trial of paclitaxel plus alisertib versus paclitaxel plus placebo in patients with second-line small cell lung cancer. This trial was published in the Journal of Thoracic Oncology in 2020. Alisertib was dosed at a different dose than in the monotherapy trial with alisertib being administered at 40 milligrams BID for three weeks on days one to three, eight to 10 and 15 to 17 plus paclitaxel dosed at 60 milligrams per meter squared IV on days one, eight and 15. The comparator on received placebo plus paclitaxel with paclitaxel dosed at 80 milligrams per meter squared IV on days one, eight and 15 in 28-day cycles. Randomization was stratified by type of relapse after primary treatment based on the common definition for each type, with sensitive defined as relapsed greater than 90%, but less than 180 days after primary treatment and resistant or refractory defined as relapsed less than or equal to 90 days after primary treatment. The protocol was initially written by the sponsor to record relapse type as the time from initial response. A protocol amendment was done approximately mid-way through the trial, which corrected the stratification definition of relapse type after primary therapy so that relapses were recorded from last administration of platinum-based chemotherapy, which is in line with the NCCN treatment guidelines and clinical treatment practice rather than from initial response. To maintain balance and the primary endpoint of PFS was analyzed using the original stratification definition of relapse type. However, sensitivity analysis, which used the corrected stratification definition was also performed. The trial also incorporated an extensive biomarker analysis with a prespecified analysis of c-Myc expression measured by immunohistochemistry and a retrospective analysis of genetic alterations in ctDNA with clinical outcome. As is shown on the slide, the primary endpoint in the trial was progression-free survival, or PFS, for the intent to treat population of the hazard ratio using the original definition was 0.77 with a p-value of 0.113, using the corrected definition, the hazard ratio was 0.71 with a p-value of 0.038. For the patients with chemotherapy resistant or refractory relapse, the hazard ratio was 0.66, with a p-value of 0.037. For the ITT population, the OS showed a hazard ratio of 0.87 with a p-value of 0.714 and using the corrected definition, the hazard ratio was 0.79 with a p-value of 0.209. As previously mentioned, there was an extensive biomarker analysis done in the trial with prospective testing for c-Myc. For the patients in the trial who were found to be IHC positive for c-Myc expression, the hazard ratio in the trial was 0.29 within median PFS for the paclitaxel plus alisertib arm of 4.64 months and a median PFS for the placebo plus paclitaxel arm of 2.27 months. The trial also incorporated an analysis of patients with alterations and cell cycle genes, including CDK6, RBL1, RBL2 and RB1. Of note, RB1 mutations were the most frequent mutation with approximately 60% of the patients having RB1 mutations, while the CDK6, RBL1 and RBL2 mutations were found with very low frequency. As shown on the slide, for patients with cell cycle mutations, the PFS in the paclitaxel plus alisertib arm was 3.68 months, while the placebo plus paclitaxel arm was 1.8 months, and the hazard ratio was 0.395 with a p-value of 0.003. The overall survival in the subgroup patients was 7.2 months for the alisertib arm and 4.47 months for the placebo arm with a hazard ratio of 0.427 and a p-value of 0.00085. Slide eight shows the AE profile for the trial, higher rates of grade 3 or higher AEs were seen in the alisertib arm for neutropenia, anemia and decreased neutrophil count, which should be expected based on the prior Phase 2 trial of alisertib monotherapy. There were also four drug-related fatalities in the trial due to neutropenic sepsis, febrile neutropenia and septic shock. Puma recently met with the FDA to discuss the clinical development plan for alisertib in small cell lung cancer with the intent of exploring the possibility of an accelerated approval pathway for alisertib in small cell lung cancer. The previous randomized Phase 2 trial of paclitaxel plus alisertib versus paclitaxel plus placebo demonstrated that in biomarker-focused subgroups, the combination of alisertib plus paclitaxel demonstrated a PFS and OS advantage compared to paclitaxel plus placebo. However, similar biomarker analyses were not performed in the previous monotherapy trial in patients with small cell lung cancer. Hence, the efficacy of alisertib monotherapy in these biomarker subgroups is unknown. In the third quarter, Puma filed its IND with the FDA for a Phase 2 trial of alisertib monotherapy in patients with small cell lung cancer. The study name is Puma ALI-4201, which is shown on slide nine. The trial will enroll up to 60 patients with extensive stage small cell lung cancer who progressed after first-line platinum-based chemotherapy and immunotherapy. Patients must provide tissue-based biopsies that biomarkers can be analyzed and alisertib will be dosed at 50 milligrams BID on days 1 through 7 and every 21-day cycle. Puma plans to perform an interim analysis for the evaluation of the biomarkers as well as an evaluation of the efficacy. Once the FDA determines the study is safe to proceed, Puma will seek to initiate this trial in the second half of 2023. As is shown on slide 10, the primary endpoint of the trial will be objective response rate, with secondary end points of duration of response, disease control, progression-free survival and overall survival. The company will also be looking at each of these endpoints within selected prespecified biomarker subgroups as well as to assess whether there is better efficacy seen in any biomarker subgroup. The goal would be to correlate the efficacy in these biomarker subgroups to the efficacy that was previously seen in the biomarker subgroups from the randomized trial of paclitaxel plus alisertib published in the Journal of Thoracic Oncology. If there is alignment between the two, the company believes it could represent a potential accelerated approval strategy. As is seen in slide 11, Puma will be performing its biomarker analysis of the ALI-4201 trial in patients -- I'm sorry, in parallel with the execution of the clinical trial. Again, the goal here will be to look at the efficacy of alisertib monotherapy and biomarker subgroups and correlate that to the efficacy seen in the same biomarker subgroups in the paclitaxel plus alisertib randomized trial. As is shown on the slide, the company anticipates meeting with the FDA once it has performed this analysis to explore the potential for an accelerated approval pathway for alisertib in small cell lung cancer. We continue to anticipate that there will be several clinical milestones for the alisertib program in the coming months. This includes potentially initiating the Phase 2 clinical trial of alisertib in small cell lung cancer before the end of the year, conducting a meeting with the FDA to discuss the clinical development and registration pathway for alisertib in hormone receptor positive HER2 negative breast cancer in the fourth quarter of 2023 and reporting data from an ongoing investigator-sponsored Phase 1/2 trial of alisertib plus pembrolizumab in the treatment of patients with RB-deficient, head and neck squamous cell cancer in the second half of this year. As mentioned on prior earnings calls, in response to investor questions, Puma continues to evaluate several drugs to potentially in-license that would allow the company to diversify itself and leverage its existing R&D, regulatory and commercial infrastructure. The company will continue to keep investors updated on this as it progresses. I will now turn the call over to Jeff Ludwig, Puma's Chief Commercial Officer, for a review of our commercial performance during the quarter.
