Thank you, Morgan, and thank you all for joining today's call. It's hard to believe that we have six weeks left in 2024. Looking back, we've navigated a tremendous amount of change at 2seventy this year. As a reminder, we ended 2023 with 277 employees, a burn rate of $63 million in the fourth quarter of 2023, and uncertainty surrounding Abecma's earlier line of approval and return to growth. In 2024, we've accomplished a tremendous amount to improve this picture. We've successfully completed the sale of our oncology and autoimmune R&D pipeline to Regeneron, including about 160 employees and the majority of our real estate footprint for the next several years. We sold our hemophilia A program and related technology to Novo Nordisk for $40 million. We received FDA approval in the third-line setting, making Abecma available to more patients living with multiple myeloma. We’ve achieved a significant return to growth for Abecma, with third-quarter U.S. revenues growing 42% over the prior quarter. The net result of these changes is that we have streamlined the company, focusing the business exclusively on Abecma, and continuing to make meaningful progress towards our goal of break-even operations. Our burn rate was approximately $10 million this quarter, and we have 70 employees, the majority of whom are funded through the Abecma Co-Co agreement with Bristol Myers Squibb. Looking ahead, we’re going to focus on two key priorities for Abecma. First, we’re going to continue to compete commercially. Abecma has an important place in a growing CAR-T market in third-line myeloma. Recent real-world evidence studies underscore that Abecma has a well-established and differentiated safety profile and has a competitive efficacy profile, particularly when patients receive effective bridging therapy prior to treatment. Second, we are working on optimizing the cost structure of Abecma to increase the operating margin cash flow from the business. The decision to discontinue enrollment in the KarMMa-9 study is an example of the kind of financial discipline we will continue to apply across the business. Together with BMS, we are looking carefully at ways to streamline expenses across clinical, manufacturing, and commercial. As we approach 2025, we are one step closer to breaking even, and as we've said, this creates strategic optionality for 2seventy. We'll have more to say when we get there, but our focus on delivering for patients and creating value for shareholders will remain our true north as we move forward. We'll get to Q&A shortly, but for now, I'll turn it over to Vicki to talk further about the third-quarter results. Vicki. Thanks, Chip. Third quarter Abecma U.S. revenues, as reported by BMS, were $77 million, which reflects ongoing expansion in the third-line setting. As Chip said, this was a strong quarter for U.S. Abecma revenue growth, and we look forward to continuing to deliver this important therapy to even more patients living with multiple myeloma. We also acknowledge that the multiple myeloma market continues to be one that is dynamic and competitive. We expect U.S. Abecma revenues to be approximately $240 million-250 million for 2024, with the fourth quarter expected to be impacted by the continued competition and a reduction in CAR-T infusions scheduled during the U.S. holiday season. As a reminder, we share equally in the profits or losses of the U.S. Abecma business with BMS, and we record collaboration arrangement revenue or loss each quarter, which largely represents our 50% share of revenue, COGS, and selling expenses related to the U.S. business. In the third quarter, we reported collaborative arrangement revenue of approximately $11 million related to our collaboration with BMS. Turning briefly to our cost structure, this quarter, we achieved a $10 million, or 24%, reduction in GAAP operating expenses versus the prior quarter, and a $140 million, or 52%, year-to-date reduction in GAAP operating expenses versus the same period last year, primarily driven by a reduction in R&D expenses. As we said before, we expect operating expenses to continue to decline in 2025 as our team prioritizes streamlining of our cost structure for both Abecma and our supporting corporate functions. We continue to expect net cash spend in the range of $40 million-$60 million for 2024 and cash runway beyond 2027. With that, I'll turn it back to Chip. Thanks, Vicki. As we close, I want to reiterate that we are encouraged by strong growth in Abecma sales this quarter and are proud to have executed on what we set out to do at the beginning of this year, bringing us one step closer to break-even, potentially as soon as 2025. We believe in the potential of Abecma to make a meaningful impact on the lives of patients and their families and plan to expand Abecma's reach to as many multiple myeloma patients as possible. I want to extend a heartfelt thank you to our people who are working hard to deliver on our mission to deliver more time to patients and their families. With that, we're happy to take questions. Operator. Thank you. As a reminder to ask a question, please press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. We ask that you please limit yourself to one question. Please stand by while we compile the Q&A roster. Our first question comes from the line of Daina Graybosch with Leerink Partners. Your line is now open. Hi, guys. Thanks for the question. I wonder now that we've been a couple quarters into this earlier line sales, if you could tell us any of your reflections on the market. I guess specifically how it differs in terms of demand in total, not just for Abecma than you had anticipated, and any earlier line dynamics that were surprises to you. Daina, thanks for the question. Yeah, I would say that the demand is sort of what we expected, different than the original launch in fourth-line plus, where there was a bolus of patients. I think this has been more of a steady build. When you look at the overall CAR-T class share between the two commercially approved products, we had a big step forward here in the third quarter. I think that's driven both by step-ups in combined manufacturing capacity, as well as more sites coming online and being in a position to deliver CAR-T to patients, as well as just continued awareness in earlier lines, third-line setting of CAR-T, of the benefit of CAR-T, of sequencing of CAR-T relative to T-cell engagers. So there's no one-stop answer, but I think what we've been encouraged by is the steady growth and pickup in CAR-T class share. And again, our view with Abecma is that we need to and will continue to compete for our place in that share. And I know you've written about that, and we were pleased to see that, particularly around recent news. But we have a meaningful share there. We have a differentiated safety profile. We have patients for whom we think Abecma can be the right treatment option. And I think the last thing I would just comment is if you look at the exit trajectory from the third quarter, we're still, by our math, less than 25% penetrated into the overall third-line setting. If you assume third-line represents something like 16,000 patients in the United States. So our view is that there's still plenty of room to grow and plenty of more patients to get to, and we're committed to trying to do that. So thanks for the question. Thank you. Our next question comes from the line of Salveen Richter with Goldman Sachs. Your line is now open. Hey, thanks. This is Matt Owen for Salveen. I was hoping you could speak to what drove the better margins for the Abecma profit share. And then separately, is $400 million in Abecma still the estimated break-even point for the overall business? And then finally, kind of given what you've guided to now for 4Q, how do you think you're positioned heading into 2025? Thank you. Matt, thanks for those questions. I'll ask Vicki to comment on margin and break-even in terms of positioning heading into 2025. We've guided here, we expect to end 2024 in the $240 million-$250 million range for total Abecma U.S. sales. Not yet guiding for 2025, but as I said in the prior question, we certainly have been encouraged by CAR-T class share growth and are leaning into continue to participate in our share of that. But Vicki, do you want to comment on margin and third quarter margin and then break-even? Yep. Yeah, thanks, Matt, for the question. I would say on the margins, we continue throughout this year, we've really continued to make steady progress on improving those margins. It's largely driven by demand. So obviously, a strong sales quarter pulls through too from a margin perspective, given the high fixed cost nature of the business. I will say too that we've continued to, with our partners at BMS, make manufacturing improvements. So we see really strong manufacturing success rates north of 95%. And so that obviously helps as you translate that into margin. On the break-even question, that's a good one. In the past, as you noted, Matt, we've guided to about $400 million being the break-even sales point for, and that's total U.S. sales for 2seventy as a whole. We think it's closer to $300 million as we sit here today, but we're very much in process of evaluating what we think for 2025. And so we'll be able to comment more on that later. But closer to $300 million is what I would guide. Thanks, Matt. Thank you. As a reminder to ask a question at this time, please press star 11 on your touch-tone telephone. Our next question comes from the line of Samantha Semenkow with Citi. Your line is now open. Hi, good morning. Thanks very much for taking the question. Appreciate the 2024 guidance and that seasonality is a big part of that. I'm wondering if you could just speak a little bit on the apheresis rates that you've seen thus far in 4Q and how they compared to the increase you saw in 3Q and how we should think about that trajectory carrying over into 2025. Thanks very much. Hi, Sam. Thanks for the call. I mean, thanks for the call. Thanks for the question. Thanks for being part of our call. Yeah, the apheresis rates, that's something that we track on a weekly basis. And again, we were very encouraged to see the growth in apheresis in the third quarter. As we sit here in the fourth quarter, again, I would say to the comments on the call, there is seasonality that occurs, particularly as people think about where they're going to be when they receive those cells and they head into Thanksgiving, Christmas, those times. That can be the intensive part of the CAR-T treatment journey for patients. And so I think we do see that. That being said, I think the underlying demand and the kind of uptick we've seen since the third-line approval back in March has been a real one. That's one that, together with BMS, we're doing everything we can be doing, we should be doing to support commercially. Again, I think we'll have more to say about 2025 at a later date, but certainly have been encouraged and really happy with the growth we've seen here in the third quarter. Thank you. And I'm currently showing no further questions at this time. I'd like to hand the call back over to Chip Baird for closing remarks. Thanks, Operator, and thanks to everyone for participating in the call today. We appreciate the time, and have a great day. This concludes today's conference call. Thank you for your participation. You may now disconnect.
