Thank you, Mariann, and thank you all for joining our call today. Today, Puma reported total revenue for the third quarter of 2023 of $56.1 million. Total revenue includes product revenue net, which consists entirely of NERLYNX sales, as well as royalties from our sublicensees. Product revenue net was $51.6 million in the third quarter of 2023, which was unchanged from Q2 2023, and $2.7 million below $54.3 million reported in Q3 of 2022. Product revenue for the third quarter of 2023 was impacted by approximately $0.6 million of inventory increase at our specialty pharmacies and specialty distributors. Royalty revenue was $4.5 million in the third quarter of 2023, compared to $3 million in Q2 of 2023 and $2.8 million in Q3 of 2022. We reported 2,874 bottles of NERLYNX sold in the second quarter of 2023, a decrease of 148 bottles from the 3,022 bottles sold in Q2 of 2023. In Q3 2023, we estimate that inventory increased by about 32 bottles. In Q3 2023, new prescriptions, or NRX, were down approximately 15% compared to Q2 2023, and total prescriptions, or TRX, were down approximately 7% compared to Q2 of 2023. Jeff will provide further details in his comments and slides. I will now provide a clinical review of the quarter, and then Jeff Ludwig will add additional color on NERLYNX's commercial activities. Maximo Nougues will follow with highlights of the key components of our financial statements for the third quarter of 2023. As we mentioned on our last earnings call, in Q3, Puma filed its IND with the FDA for a phase II study of alisertib monotherapy in patients with small cell lung cancer, known as Study PUMA-ALI-4201. The trial will enroll up to 60 patients with extensive stage small cell lung cancer who have progressed after first-line platinum-based chemotherapy and immunotherapy. Patients must provide tissue-based biopsies so that biomarkers can be analyzed. Alisertib will be dosed at 50 milligrams BID on days 1 through 7 of every 21-day cycle. Puma plans to perform an initial interim analysis for the evaluation of the biomarkers, as well as an evaluation of the efficacy. As we discussed in our last earnings call, the goal of this phase II study will be to confirm the efficacy of alisertib monotherapy in patients with small cell lung cancer, with biomarkers where the Aurora kinase pathway plays a role....The goal would be to correlate the efficacy in these biomarker subgroups in the PUMA-ALI-4201 study, to the efficacy that was previously seen in the biomarker subgroups from the randomized trial of paclitaxel plus alisertib versus paclitaxel plus placebo, that was published in the Journal of Thoracic Oncology in 2021. If the efficacy and biomarker data are comparable from the two studies, the company believes it could represent a potential accelerated approval strategy. In August, we announced that the FDA had determined that the phase II PUMA-ALI-4201 study was safe to proceed. We expect to have multiple sites open for enrollment between now and the end of the year, and we are hopeful that we will be able to enroll patients by year-end, although we recognize the challenges of trying to enroll patients during the November and December holidays. We continue to anticipate that there will be several clinical milestones for the alisertib program in the coming months. This includes initiating a phase II 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 path for alisertib in hormone receptor-positive, HER2-negative breast cancer in the fourth quarter of 2023, and then initiating the phase II trial of alisertib in this patient population in 2024. As mentioned on prior earnings calls and 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 Puma's 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. Thanks, Alan, I appreciate it, and thanks to everyone for joining our third quarter earnings call. Before I move into the commercial review, just a reminder that I will be making forward-looking statements. Now, let me start with an overview of our commercial strategy. We remain largely focused on the extended adjuvant indication for NERLYNX, where about 90% of our business is generated. We believe there continues to be significant unmet need, especially for patients at higher risk of reoccurrence. We also believe that NERLYNX is promotionally sensitive, and given this, our sales and marketing teams are focused on increasing reach and frequency with both personal and non-personal promotion. It's important to engage with customers at the right time, given the various treatment decisions and duration of therapies. As a commercial organization, we are committed to becoming more efficient and more effective with our resources, and we'll adapt appropriately based on changes in the business. Let me transition to some of the commercial slides, where I will provide additional specifics around performance. Once I've finished, I'll turn the call over to Maximo for a more detailed review of our financial results. Turning to slide three. Slide three provides an overview of our distribution model. Now, this model has not changed and remains separated into two distinct channels that provide NERLYNX to patients. We refer to these channels as our specialty pharmacy channel and our specialty distributor channel. Most of our business continues to flow through the specialty pharmacy channel. In Q3 of 2023, approximately 80% of our business went through the specialty pharmacy channel, which is up from the 74% we reported in Q2 of this year, and identical to what we reported in Q3 of 2022. Turning to slide 4. NERLYNX net revenue in Q3 of 2023 was $51.6 million, which is identical to what we reported in Q2 of 2023, and down approximately $2.7 million from what we reported in Q3 of 2022. Inventory changes can have an impact on these numbers, so let me give you some additional insights, which I've also included on this slide. In Q3 of 2023, we estimate that inventory increased by about $600,000. As a comparator, we estimate that inventory increased by about $500,000 in Q3 of 2022, and decreased by about $1.5 million in Q2 of 2023. Slide 5 shows Q3 ex-factory bottle sales, and also provides both a year-over-year and a quarter-over-quarter comparison. In Q3 of 2023, NERLYNX ex-factory bottle sales were 2,874, which represents about a 5% quarter-over-quarter decline and about a 10% year-over-year decline. Let me again provide more specifics around the inventory impact, which is also included at the bottom of this slide. We estimate that inventory increased by about 32 bottles in the third quarter of 2023. As a comparison, we estimate that inventory increased by about 30 bottles in Q3 of last year and declined by about 89 bottles in Q2 of 2023. Let me provide some additional metrics and insights into our third quarter performance. In Q3, we saw new patient starts or NRX decline about 15% quarter-over-quarter and about 30% year-over-year. In terms of total prescriptions, we saw about a 7% decline quarter-over-quarter and about 11% decline year-over-year. As a reminder, we do not pick up NRX or TRX data in the SD channel, so we do not have the same level of visibility for patients that start and stay in the SD channel. In regards to demand, we saw demand decrease about 8.5% quarter-over-quarter and about 10% year-over-year. Now, our Q3 performance was heavily driven by a decline in enrollments that occurred for several consecutive weeks early in the quarter. We saw a solid increase in enrollments in June, but saw a significant decline in enrollments starting the second week in July and continuing through early August. We reached out to customers across the country to inquire about patient flow and patient volume. Although there was some reported softness, it was not a consistent trend. Since that early softness, which occurred largely in July, we have seen steady monthly improvement with enrollments trending positively month-over-month throughout Q3. In addition, October enrollments have continued that positive trend and are in line with enrollments seen in Q1 and Q2. Slide 6 highlights the adoption of dose escalation. Dose escalation is an important metric for us, as it serves to improve the tolerability of NERLYNX by significantly reducing grade 3 diarrhea and decreasing overall discontinuation rates. In Q3, approximately 71% of patients who received commercial drugs started NERLYNX on a lower daily dose. We have seen a fairly steady increase in the adoption of dose escalation over the last several years, and I'm overall pleased with that uptake. Moving to slide seven. Slide seven highlights the strategic collaborations we have formed across the globe. In Q3, we are very pleased to announce that NERLYNX received regulatory approval in the metastatic setting in Malaysia, and was also formally launched in the metastatic setting in Colombia. We truly appreciate the efforts by all of our partners to continue to make NERLYNX available to more patients around the world. I'd like to wrap up by thanking my colleagues for their support and commitment. The team is absolutely passionate about making a difference in the lives of patients battling cancer. They are also committed to being more efficient and more effective with their resources, and they are committed to balancing the short-term and long-term priorities of Puma and its shareholders. I will now turn the call over to Maximo for a review of our financial results. Maximo? Thanks, Jeff. I will begin with a brief summary of our financial results for the third quarter of 2023. Please note that I will make comparisons to Q2 2023, which we believe is a better indication of our progress as a commercial company than year-over-year comparisons. For more information, I recommend that you refer to our Q3 2023 10-Q, which will be filed today and includes our consolidated financial statements. For the third quarter of 2023, we reported net income based on GAAP of $5.8 million or $0.12 per share. This compares to a net income in Q2 2023 of $2.1 million, or $0.05 per share. On a non-GAAP basis, which is adjusted to remove the impact of stock-based compensation expense, we reported net income of $8.3 million or $0.18 per share for the third quarter of 2023. Gross revenue from NERLYNX sales was $60.4 million in Q3 2023, and $62.8 million in Q2 2023. As Alan mentioned it, net product revenue from NERLYNX sales was $51.6 million, unchanged from the $51.6 million reported in Q2 2023. We believe that Q3 net sales were impacted by approximately $600,000 of inventory increases from our distributors, versus approximately $1.5 million of inventory drawdown in Q2 2023. Royalty revenue totaled at $4.5 million in the third quarter of 2023, compared to $3 million in Q2 2023. The higher royalties versus Q2 reflect the timing of shipments to our partner in China, as we noted last quarter. Our gross-to-net adjustment in Q3 2023 was about 14.6%, compared to the 17.9% gross-to-net adjustment reported in Q2 2023. Lower Medicaid rebates was the main driver of the decrease versus Q2 2023. In Q3 2023, we released prior period accruals related to expected medical rebates that have not materialized to date. Cost of sales for Q3 2023 was $13.3 million, including $2.4 million for the amortization of intangible assets related to our neratinib license. Cost of sales for Q2 2023 was $11.9 million. Going forward, we will continue to recognize amortization of milestones to the licensor of about $2.4 million per quarter as cost of sales. For fiscal year 2023, Puma anticipates that net NERLYNX product revenue will be in the range of $206 million-$209 million. We also anticipate that our gross-to-net adjustment for the full year 2023 will be between 17.5%-18%. In addition, for fiscal year 2023, we anticipate receiving royalties from our partners around the world in the range of $30 million-$32 million. We don't expect license revenue in 2023. We also expect that net income for the full year will be in the range of $22 million-$25 million. Our royalties in the fourth quarter are dependent on shipments to our ex-US partners that are expected to occur between now and the end of the year. If there are any delays to these shipments, it could adversely impact our revenue. We anticipate that for Q4 2023, NERLYNX net product revenue will be in the range of $56 million-$59 million. We also expect Q4 royalty revenues will be in the range of $16 million-$19 million. We further estimate that the gross-to-net adjustment in Q4 2023 will be approximately 15.5%-16.5%. Puma anticipates a Q4 net income between $13 million and $16 million. SG&A expenses were $22.8 million in the third quarter of 2023, compared to $24.4 million for the second quarter. SG&A expenses included non-cash charges for stock compensation of $1.8 million for Q3 2023, unchanged from Q2 2023. Research and development expenses were $11.4 million in the third quarter of 2023, compared to $13.4 million for the second quarter. R&D expenses included non-cash charges for stock-based compensation of $0.8 million in the third quarter of 2023, unchanged from the second quarter. In the third quarter of 2023, Puma reported cash earned of approximately $10.6 million. This compares to cash earned of approximately $3.2 million in Q2 2023. On the expense side, Puma continues to anticipate a reduction in total operating expenses in 2023 compared to 2022. More specifically, we anticipate SG&A expenses to be flat or increased by approximately 1%-2% and R&D expenses to increase 1%-3% year-over-year. At September 30th, 2023, we had approximately $85 million in cash, cash equivalents, and marketable securities. Our accounts receivable balance was $29 million. Our accounts receivable terms range between 10 days and 68 days, while our days sales outstanding are about 45 days. We estimate that as of September 30, 2023, our distribution network maintained approximately 3 weeks of inventory. Overall, we continue to deploy our financial resources to focus on the commercialization of NERLYNX, the development of alisertib, and controlling our expenses. Thanks, Maximo. We are pleased to report positive net income as well as positive cash flow during the third quarter of 2023. Puma senior management, in cooperation with the board of directors, continues to remain focused on improving NERLYNX sales in 2023 and beyond. In fourth quarter of 2021, we implemented a reduction in expenses with the goal of reducing expenses in order to maximize operating cash flows. We believe that the positive net income and cash flow reported in the third quarter reflect these expense reductions. The expense reductions that we have previously performed and continue to perform are also a major contributor to the positive net income and positive cash flow that the company is anticipating for full year 2023. The company remains committed to continuing to achieve these operational cash flows and positive net income, and will continue to reduce expenses if needed in order to achieve this. We look forward to updating investors on this in the future. There continues to remain a significant unmet need for patients battling breast cancer, lung cancer, and other solid tumors. We at Puma are committed and passionate about finding more effective ways at helping these patients during their journey, and we will continue to strive to achieve that goal. This concludes today's presentation. We will now turn the floor back to the operator for Q&A. Operator? Thank you. We will now begin the question-and-answer session. If you wish to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate that your line is in the question queue. If you wish to withdraw your question, please press star two. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment, please, while we pull for questions. Thank you. Your first question comes from Ed White with H.C. Wainwright. Please proceed with your question. Hi, good afternoon. Thanks for taking my questions. First question is just sort of a housekeeping thing, and maybe I missed it, but what was the% of free drug that you experienced this past quarter? I'm looking for that exact percentage, and if you just give me a moment, I'll find that to you. But we've not seen any significant change in free drug increases or decreases over the last several quarters. So, give me one second as you ask your second question, I'll give you a percent there. Okay. Yeah, Jeff, the other question was for you, too, and just wanted to get a little bit more color about the new prescription weakness in July and into August, and what gives you confidence that you'll see a recovery in the fourth quarter? Hey, thanks for the question. And we free drug, we're about 14% of free drug, and that's been fairly consistent for us over the last several quarters in terms of total bottles. Great question on the softness we saw in early. And let me just remind you what I said up front and give you a little bit more color. As I mentioned, we did have solid enrollments in June and the first week in July, but we did see a drop starting the second week in July for about 5 weeks. Obviously, we looked at those trend changes, and as I mentioned in my opening remarks, we reached out to customers across the country to check on patient flow or any kind of patient impact there, and we just didn't see anything consistent. As you can guess, we also looked at any other factors just to make sure nothing's impacting sales from pathways, formularies, competitive activities, and there was nothing significant from that standpoint either to point out. ... We do look internally, and I'll tell you, as I mentioned many times, we do believe NERLYNX is promotionally sensitive. And so as I look at Q3, as not uncommon for Q3, with holidays and vacations, we do tend to see a slight drop in call activity in Q3. We saw that. That tends to occur early, and we expect that to improve. We also pay very close attention to our broader promotional efforts as well, non-personal promotion, et cetera, and we looked at that throughout Q3. We've made some adjustments to ensure it stays broad and wide, to make sure that we have good reach and frequency moving forward. As a reminder, we did see that softness in early July, but as I mentioned, we saw improvements in August. We saw improvements in September. We also have seen that trend continued in October. So as you asked me, the final part of your question was, what gives me confidence that we're seeing changes? It is the numbers and the trends that we're seeing. Hopefully, that helps. Yes, Ed, if I can jump in here. If you wanna kind of think about how the enrollments have looked so far this year, we always see a spike up in January because you get the patients who didn't wanna go on the drug due to the side effect profile, which is, you know, usually in that first month, who didn't wanna go on it in December for the holidays, so in January, we always get a big spike. It's kind of relatively similar, February, March, April, May, then it jumped up in June, and then it jumped down in July. And then August was higher than July, September was higher than August, and October was higher than September, and October was more basically very in line with that baseline that had been set in that kind of February through May time period. So look, you can speculate, okay, is the June spike, people who would have gone out in July or taking vacations or whatever and wanted to be through the side effects, that could be. You know, remember that, you know, patients have up to two years from when they complete adjuvant therapy to take NERLYNX. So it gives them a little more flexibility on when they start. It's not like a metastatic disease, where you have to start right away, because of the disease. So, you know, we're in year six of launch. To my recollection, we have seen this drop in July before, and I think back then, our assumption was, it's the holidays or, you know, it's people taking vacations or whatever. Again, it's not something we're really, like Jeff said, the numbers have come back to what they were previously. We don't really think it's, you know, anything to be concerned about. Okay, thanks for the added color. And also, could I get your thoughts on, you know, ex-U.S. sales potential? Obviously, you raised royalty revenue guidance. It seems like, you know, this impact is, is somewhat, you know, overlooked by the investors, and I just wanted to get your thoughts on the potential outside the U.S. for sales, particularly in China. Yeah, thanks, Ed. So the launch in China is still rolling out, and our partner has done a wonderful job there. You know, we do tend to see, if you look at the numbers, you know, a big bolus of the royalties coming in in this Q4. So we're expecting that this year, just like we did last year. The rollout is still going, and they've done a nice job with the growth. We've been very, very pleased with their execution. You know, I would say China is probably, you know, second largest market for us, just due to number of patients. And I think in terms of our royalties, that's where it looks like it's coming. It's probably the highest area that we're seeing royalties from. So, you know, I think, I think it's still got some momentum to go there, and, you know, the numbers obviously show that, and I, I would, you know, look forward to continuing to see that in the future. Great. Thanks, Alan, for taking my questions. Thank you. Our next question comes from the line of Divya Rao with Cowen. Please proceed with your question. Hi, guys. This is Divya. I'm for Marc. Thanks for taking my question. I wanted to get a better idea of the phase III trial of alisertib in metastatic breast cancer. I know that you've yet to speak with the FDA, but do you anticipate having... or I guess, in an ideal scenario, would you like to have a similar trial design to what you see with the small cell phase II? Or is there a potential that you could explore a combination therapy here? And then a follow-up to that, just given the other agents that are also being developed in this space, how do you guys define success in this trial? Thanks. Thanks for the question, Divya. So, with alisertib, we are very focused on, you know, the biomarker populations, where there's a biomarker that's indicative of the Aurora kinase pathway being activated. And so in the small cell lung cancer trial, for example, you know, you saw that with the c-MYC and with the, you know, RB1 mutations, and there's a few others, you know, that haven't yet been published as well. In terms of your question, you know, you're correct. The small cell lung cancer, the previous trial done was paclitaxel plus alisertib against paclitaxel plus placebo. You know, the feedback we've been getting from the KOLs has been they would like to use it earlier, kind of in the pre-chemotherapy setting. So it would be more similar to, you know, the study that was done, the TBCRC 41, where it was kind of alisertib with endocrine therapy. That would be kind of where they would like to position the drug. And specifically, where they've kind of looked to position it, would be kind of, you know, after the patient has had CDK4/6, you know, perhaps after they've had another agent that's, you know, also involving an endocrine therapy and then kind of using it in that, in the pre-chemo setting. So that would be where we'd be positioning it. You had a follow-up question as well? Yeah, that's helpful. I just wanted to know, just given the other agents that are being developed, like how do you... And the KOLs, like, how do you define success in this trial, if it is a single agent trial in this setting? Yeah. So I don't know if the trial will be alisertib alone or alisertib plus endocrine. That would obviously be an easier trial to do, like alisertib plus endocrine against placebo plus endocrine. So it's, you know, a well-designed, well-controlled trial. You're correct, there's a lot of other agents, you know, a lot of the ADCs especially, but that tends to be in more the, you know, chemo and post-chemo setting, not this kind of pre-chemo setting. In terms of what success would look like, you know, there is a good precedent here in ER-positive, HER2-negative breast cancer for a targeted agent being developed in the pre-chemo setting, which is, you know, Piqray, which is the PIK3CA mutation drug. I think that kind of, you know, playbook, if you will, would be what we'd be looking to do, which was developed in a pre-chemo population. You know, it was, you know, Piqray plus endocrine against endocrine alone. That type of design and that type of, you know, outcome would be what we'd be looking for. That's really helpful. Thank you so much. Sure. Thank you. Our next question comes from the line of Gina Wang with Barclays. Please proceed with your question. Hi, good afternoon. This is Rashida on for Gina. Thanks for taking our questions. A couple of quick ones, perhaps for Alan. Alan, for the Q4 FDA meeting for breast cancer, did you already request the meeting? Yep, meeting is requested and has been scheduled. It's either this month or next month. I can't remember which one. Oh, perfect. Thanks for the clarity on that. And then second, I had a question on... And I understand you know, you provide very detailed guidance, you know, in the quarters to come and for the, you know, full year 2023, you provided guidance. But as you know, alisertib, you're starting the small cell lung cancer trial, and then, you know, the breast cancer trial will probably, you know, potentially start in 2024. Are you able to provide any color right now on how we should see, like, expenses changing with, you know, regards to R&D? Any color you can provide on that would be helpful. Yeah. So from an R&D perspective, remember that we still have some neratinib R&D items on, in the forecast, which is, you know, we're still closing down a lot of the previous sites, so those have to come out. And then there is a... In Europe, we had a post-approval commitment study, which was a study of neratinib using... It basically was similar to the control study, but being done in the European population. So it was neratinib and extended adjuvant, looking at all the different ways of reducing the diarrhea. That study will be concluding shortly, and so the expenses from that will be coming out as well. So we do have a lot of R&D budget items coming out. You're correct, going in, we, you know, coming into the expenses would be the alisertib, small cell lung and HR-positive breast. You know, we had gotten a question earlier, and I think we got one at one of the conferences as well on that. And what we had said was, "Listen, it is very important to us that we continue to be a net income positive company. So if we have to stagger the development of the drug in order to do that, then that's what we're going to do." We completely recognize our responsibility to shareholders, not just in developing new drugs, etc., but also our fiscal responsibility. And so we think that is something very important, is being able to be a net income positive company. If we have to stagger the expense, stagger the trials in order to do that, that's what we're going to do. Our commitment is to maintain net income positivity. That, that's helpful. Thank you, Alan. And I just had one last quick question. Are you able to disclose how many sites you anticipate on opening for the small cell lung cancer trial? I mean, small cell trial. That is a good question. I apologize, I don't have that number in front of me. My ballpark memory is like 10-15, if I remember. Maybe it's 20. Somewhere in that general range, 10-20. No worries. Still, still helpful. Thank you so much. Sure. Thank you. This concludes our question and answer session, and I would now like to turn the conference back over to Mariann Ohanesian for closing remarks. Thank you for joining us today. As a reminder, this call may be accessed via replay at pumabiotech.com beginning later today. Have a good evening. Ladies and gentlemen, thank you for participating in today's conference call. This does conclude our program. Thank you, and have a great day.
