I would now like to turn the call over to our President and CEO, Mike Rossi.

Thank you, Courtney. Good morning, and thank you for joining us. I have with me today our Chief Commercial Officer, Sue Smith, our Chief Medical Officer, Dr. Vinash Rajah, and our Chief Financial Officer, Pete Frinshaw. This morning, I will begin by reviewing key financial and operational highlights from the third quarter of 2024, including Daniela's sales performance, and the clinical progress of our radiotherapy clinical programs utilizing our self-assembly, disassembly, pre-targeted radioimmune therapy, or SADA print technology platform. Next, Sue will provide details on our global Danielza sales in the third quarter. Vinesh will then provide updates around our ongoing Nexidimab ISS clinical trials. Then Pete will review our third quarter 2024 financial performance, our cash resources, and reiterate our full 2024 guidance before we open the line for Q&A. Let's begin with the key highlights for the third quarter of 2024, starting with Danielza. Danielza, the brand name for a humanized anti-GD2 therapy, Nexidimab, is FDA approved for the treatment of children aged one year and older with relapsed refractory high-risk neuroblastoma in the bone or bone marrow. Neuroblastoma continues to be the most common cancer in infants and the third most common cancer in children. Danielza is specifically designed for children who have had an incomplete response to induction or relapse therapy and also have disease in the bone and or bone marrow. While designated as an outpatient therapy, Danielza can also be administered in the inpatient setting depending on the specific needs of the child. We are nearing the four-year mark since the commercial launch of Danielza in the US. Despite some of the headwinds around competition we saw from the second quarter carry into the third quarter this year, our overall commercial progress since launch back in 2021 shows encouraging continued progress in terms of the number of sites we are able to reach and the patients we are able to treat with Danielza. In the third quarter, we added three new US Danielza accounts and saw a 5% increase in Danielsa demand compared to the second quarter of this year. This signals to us increasing physician adoption of Danielsa across both new and existing accounts and more patients having access to this important anti-GD2 therapy. Our team continues to drive important initiatives around direct-to-parent education and patient advocacy efforts with the goal of thoroughly understanding the current gaps in patient care and increasing awareness of Danielza as an important treatment option for children with relapsed refractory high-risk neuroblastoma to achieve a complete response and remission. You will hear more from Sue on specifics around Danielza's performance across our U.S. and ex-U.S. markets shortly. In the third quarter, we achieved total net revenue of $18.5 million, down 10% from the same period in 2023. The decrease was due to a decline in net product revenues in both the US and our ex-US markets in the quarter, in addition to a half million dollar in licensing revenue recorded in the third quarter of 2023. For the first nine months of the year, we achieved total net revenue of 61.2 million US dollars, relatively consistent with the same period in 2023. We had several corporate updates in the quarter that support our continued global commercial and indication expansion efforts. We are thrilled to have received notification of the accepted patent extension for Danielza, U.S. 9315-585 last month. Our U.S. patent will now expire February 5th, 2034, extended from June 20th, 2031. In the third quarter, we entered into a lease agreement for a future YMAPS headquarters in Princeton, New Jersey. We expect the construction of the premises will be completed in the first half of 2025, and the lease will run for 10 years and nine months from the completion date. Earlier this week, we announced that we have entered an exclusive license agreement and distribution agreement with Noble Pharma for the development and commercialization of Danielza in Japan, if approved in the region. We received an upfront payment of $2 million, which will be recorded in the fourth quarter of this year. Under the terms of the agreement, we are entitled to receive up to 31 million U.S. dollars in product and commercial milestone payments in addition to profit sharing on the commercial sales of Danielsa if successfully approved and commercialized in Japan. Japan represents an important Asia region for Danielsa, and we look forward to partnering with Noble Pharma and expanding access to Danielsa to the region if approved there. Our partner, TR Farm, launched the Danielza Named Patient Program in Turkey in the third quarter of 2024. We are very pleased with how the launch is progressing and look forward to providing further updates in future quarters. In addition, with our Latin American partner, ADM, we plan to submit a regulatory filing for marketing approval of Danielza in Argentina later this year. Overall, we remain confident in our U.S. commercial strategy and trajectory in the continued XUS expansion of Danielza to fill important gaps in the treatment of children with relapsed or refractory high-risk neuroblastoma. Let's now shift to our SADA-PRIP programs, starting with our Phase I trial evaluating the safety and tolerability of GD2 SADA for the treatment of GD2-positive solid tumors. This is a basket trial looking at small-cell lung cancer, sarcomas, and malignant melanomas. In the fourth quarter, we opened cohort six to include adult patients 16 years of age or above with high-risk neuroblastoma. As a reminder, this phase one dose escalation single-arm multicenter safety study has three parts. Part A, which we are currently in, is structured to demonstrate the safety profile of the protein while it explores dose finding for the GD2 SADA molecule and testing of the dose intervals of two to five days between the protein and the lutetium-dota payload. Part B aims to determine the optimal dose of lutetium-177-dota, and Part C will evaluate the safety and initial signs of efficacy using repeat dosing. To date, we have six sites open and have a total of 20 patients in Part A of this trial. We have completed cohorts one through five using a radioactive payload of up to 200 millicuries of lutetium and two to five day interval between SADA protein and payload. The initial blood pharmacokinetic profile of the construct in these patients dosed with 0.3 milligram per kilogram, one milligram per kilogram, and three milligram per kilogram of protein appears to match our preclinical models in the terms of clearance data, and blood PK profiles from patients are comparable and supportive of the current dose interval between two and five days. We continue to be encouraged by what we have seen so far. To date, no patients in the trial have experienced any dose-limiting toxicities, and there have been no instances of treatment-related serious adverse events. Based on the SPECT CT scans and PK activity we have seen to date, We believe we have demonstrated proof of concept in humans that GD2 SADA can both find and bind to tumors. It is important to note that these early data are not complete and not necessarily indicative of a full result or ultimate success of the trial or the SADA development program. We are on track to complete Part A of this Phase 1 study by the end of this year, and we'll look to present a full data set from Part A in the first quarter of 2025. In the anticipated data readout from Part A of the trial, our objective is to demonstrate the safety profile of the protein and determine the optimal timing to administer the radionuclide, all of which will inform Part B. We also plan to show additional scan images and PK data. Because we elected to open a sixth cohort to include adults with neuroblastoma, we are awaiting the full data from Part A before filing an IND for a GD2 SADA Phase I trial in pediatric neuroblastoma. Our second SADA program is CD38 SADA, which we are first studying in the treatment of non-Hodgkin's lymphoma, focusing on B-cell and T-cell lymphoma. This is our first SADA program in circulating tumors. Our planned phase one follows the design comparable to our GD2 SADA phase one trial, which you can see here. We have selected the first six sites and activated two sites and expect to dose the first patient by the end of 2024. In addition, we look forward to highlighting preclinical CD38 SADA data in a poster presentation at the American Society of Hematology annual meeting on December 7th in San Diego. The abstract, titled CD38 SADA, a self-assembling and disassembling bispecific fusion protein for two-step pre-targeted radioimmune therapy of non-Hodgkin's lymphoma, is available on the ASH website. We are very excited for the potential of SADA-PRIT to fill much needed gaps for patients across a range of cancers and potentially other serious diseases, and we continue to believe in its potential advantages in manufacturing, administration, and logistics with traditional radiopharmaceuticals. We look forward to providing further updates on our SADA-PRIT programs going forward. Across both our Danielzit and SADA-PRIT platforms, we are committed to advancing a potential new generation of therapies through clinical development aimed at improving outcomes and long-term quality of life for patients and their families. I will now pass the call over to Sue Smith to provide further color on global Daniela sales for the third quarter of 2024.

Thank you, Mike, and good morning, everyone. Despite seeing some of the same headwinds we saw in the second quarter carrying to the third quarter, we're pleased with the overall commercial progress of Danielza since the initial commercial launch in the U.S. and across our ex-U.S. markets. Danielza is an important anti-GD2 therapy for the physician toolbox in the treatment of patients with relapsed refractory high-risk neuroblastoma in the bone or bone marrow. Its key unique features including outpatient administration and response in bone and or bone marrow, makes Danielsa an important treatment option for patients and caregivers alike. In the third quarter of 2024, total U.S. Danielsa net product revenues were $15.3 million, representing a 5% decrease compared to the same period in 2023, primarily driven by a change in estimate from Medicaid claims. While we encountered continued competition from the launch of a new market entrant for maintenance therapy, in addition to ongoing clinical trial activity, we still saw increases in key performance indicators. A total of 68 accounts have now used Danielza around the U.S. since its initial launch in 2021, with three new accounts added in the third quarter of 2024. Danielza's estimated total share of the U.S. anti-GD2 market remain steady at approximately 15% as of September 30th, 2024. We're excited to see physician utilization of Danielza continue to grow. 34 health practitioners started patients on Danielza in the nine months ended September 30th, 2024, with seven physicians starting treatment on two or more patients. Since launch, a total of 113 healthcare providers have prescribed Danielza and 34 of those have started treatment on two or more patients. Our dedicated U.S. commercial sales team continues to receive positive healthcare provider feedback on Danielza through ongoing customer interactions. In addition, we continue to see institutional adoption of Danielza, which has been added to two hospital formularies in the third quarter of 2024, bringing the total since launch to 48 hospital formularies as of September 30, 2024. Now, turning to our XUS commercial progress, XUS, our third quarter 2024, Danielle's net product revenues were $3.1 million, a decrease of 19% compared to the third quarter of 2023. The decrease was primarily driven by a decline in volume from our WEP patient access program in Europe, which had an initial stocking order in the third quarter of 2023. The third quarter marked the first recorded sales in Turkey with our partner TR Farm and the second consecutive quarter of Danielza sales in Brazil and Mexico, led by our Latin American partner ADM. We expect to see additional adoption over the coming quarters and look forward to providing further updates as we learn more about market dynamics in these regions. In Asia, our partner Cyclone continues to expand use of Danielza in China and is gearing up to launch Danielza in Hong Kong following its approval in the region last quarter. Our team is committed to finishing the year with strong fourth quarter performance of Danielza in the U.S. and continuing to support our ex-U.S. partners as they expand access to Danielza across their respective regions. We are confident in the potential to position Danielza as the anti-GD2 therapy of choice in relapsed refractory high-risk neuroblastoma in the bone and or bone marrow to both physicians and caregivers and expect to see a continued overall upward trend of sales growth over the long term. We look forward to providing further updates throughout the coming year. I will now pass the call to Vignesh.

Thank you, Sue, and hello, everyone. I'm pleased to provide a brief update on our ongoing investigator-sponsored Nexudimab clinical trials. Let's start with Memorial Sloan Kettering Cancer Center's Phase II clinical trial evaluating Nexidimab in patients with second-line relapsed osteosarcoma. As we shared during our second-quarter earnings call, based on a draft abstract our team received from MSK back in June, the trial did not meet its primary endpoint of 16 event-free patients at 12 months, and instead stated that there were 14 event-free patients at 12 months. MSK is expected to present its data at a medical meeting by the end of this year, after which time our team plans to analyze the full study results and evaluate next steps. In the frontline high-risk neuroblastoma setting, our partner, the Beat Childhood Cancer Research Consortium, or BCC, is leading a multicenter phase two trial evaluating Nexidimab in combination with standard induction therapy for patients with newly diagnosed high-risk neuroblastoma. As of the end of the third quarter, the BCC had 22 active sites and treated 11 patients with recruitment ongoing. The amended protocol for the transition to a comparison with an external control is currently being developed. We expect the trial to transition from a single arm trial design to a comparative trial with an external control arm that reflects current standard of care for induction therapy with a comparable patient population that is carefully selected and propensity score matched. Our aim for the trial is to demonstrate superiority in complete response rates at the end of induction therapy in the Nexidimab arm compared to the standard of care. In advanced breast cancer, we're partnering with the Ohio State University on a phase 1B trial investigating TGF-beta NK cells gemcitabine, and naxidimab in patients with GD2-positive metastatic breast cancer. Patient recruitment for the trial was initiated in the third quarter of 2024. As per the study design, follow-up for dose-limiting toxicities with a combination of gemcitabine and NK cells need to be completed, and the persistence of NK cells in the blood needs to be confirmed before the addition of naxidimab. Upon the outcome of this trial, we would consider moving forward with a multicenter phase two trial. In patients with refractory Ewing sarcoma, the Institute of Mother and Child in Poland is leading a randomized phase two trial evaluating the efficacy and safety of Nexidimab. This trial was initiated during the fourth quarter of 2023. Three patients have been dosed in the Nexidimab arm to date, and recruitment is ongoing. We expect a total of 16 patients in that arm. The trial is expected to be completed in 2028. In addition, we're in discussions with the MD Anderson Cancer Center to initiate a multicenter phase one study to evaluate the addition of Nexidimab to current standard of care in the treatment of metastatic triple negative breast cancer. The study is expected to assess the safety of this combination as well as provide an early indication of objective response rate in patients with metastatic triple negative breast cancer who have received at least one prior line of systemic therapy for metastatic disease. The study, which is anticipated to start in the first quarter in 2026, will further inform us on a future phase two program in triple negative breast cancer. We believe a significant treatment gap remains in the anti-GD2 space in both pediatric and adult cancers. We're committed to supporting the advancement of these investigator-sponsored studies through clinical development and working to unlock the untapped potential of mexidimab. Let me now hand the call over to Pete Freundschuh.

Thank you, Vignesh, and good morning, everyone. As you heard earlier, we recorded total Danielza net product revenues of 18.5 million in the third quarter of 2024. representing a 7% decrease compared to 20.0 million total Danielsa net product revenues in the third quarter of 2023, primarily driven by decreased international and U.S. revenues from a decline in U.S. and ex-U.S. order volumes. U.S. Danielsa net product revenues were $15.3 million and $16.1 million for the three months ended September 30, 2024, and 2023, respectively, representing a 5% decline. The decline was primarily due to an unfavorable price mix, partially offset by increased U.S. volume of 5%, during the third quarter of 2024 compared to the third quarter of 2023. Ex-U.S. net product revenues were $3.1 million and $3.9 million where the three months ended September 30, 2024 and 2023, respectively, representing a 19% decline. The decline was primarily driven by decreased volume from Western Europe in the quarter. We received an inventory order from Cyclone of $1.7 million in the third quarter, but the revenue was recorded in the fourth quarter due to cutoff timing issues. Our total Danielza net product revenues of $60.7 million for the nine months ended September 30, 2024, were relatively flat compared to $61 million where the nine months ended September 30th in 2023. We did not have licensing revenue for the three months ended September 30th, 2024. We did report 0.5 million of licensing revenue in the nine months ended September 30th, 2024. We also reported 0.5 million of licensing revenue for the three and nine months ended September 30th, 2023. Moving to operating expenses, our research and development expenses were $11.2 million and $36.8 million for the quarter and nine months ended September 30, 2024, representing decreases of $4.2 million and $4 million from $15.4 million and $40.8 million for the quarter and nine months ended September 30, 2023. Selling general and administrative expenses increased by $3.4 million and $8.5 million to $13.6 million and $42.3 million for the three and nine months ended September 30, 2024, respectively, compared to the same periods in 2023. The increase in selling general and administrative expenses for the three months ended September 30, 2024 was primarily attributable to a $1.2 million increase related to our former chief financial officer separation and consulting agreements and a $1.1 million increase in personnel costs inclusive of stock-based compensation and $0.5 million in professional and consulting fees. The increase to selling general and administrative expenses for the nine months ended September 30th, 2024 was primarily attributable to a net impact of 3.8 million related to two legal settlements that were finalized in the nine months ended September 30th, 2024. As previously mentioned, The increase also includes a $1.2 million increase related to our former chief financial officer's separation agreement and consulting agreement, a $1.1 million increase in personal costs inclusive of stock-based compensation, and $0.8 million in professional and consulting fees. We reported a net loss for the quarter ended September 30, 2024 of $7 million or negative 16 cents per basic and diluted share compared to a net loss of 7.7 million or a negative 18 cents per basic and diluted share for the quarter ended September 30th, 2023. In addition, we have reported a net loss for the nine months ended September 30th, 2024 of 22.9 million or negative 52 cents per basic and diluted share as compared to a net loss of 20.4 million or a negative 47 cents per basic and diluted share for the nine months ended September 30th, 2023. The decrease in net loss for the three months ended September 30th, 2024 was primarily driven by decreased operating expenses and a favorable impact from foreign currency transactions, partially offset by decreased product revenues net. The increase in the net loss for the nine months ended September 30, 2024, was primarily driven by the previously mentioned two legal settlements with a net 3.8 million impact. As mentioned earlier, We ended the third quarter of 2024 with cash and cash equivalents of 68.1 million as compared to 78.6 million at year end 2023, representing a decrease of 10.5 million year to date. Importantly, we continue to maintain a strong balance sheet, reporting 9.7 million in cash outflows for the third quarter of 2024, primarily driven by cash payments on the two previously mentioned legal settlements paid within the quarter. Turning now to our full year 2024 guidance, We reiterate our full year 2024 total net revenue guidance to be in the range between 87 and 95 million, but we expect the revenues will come in in the bottom half of that range. We continue to anticipate our operating expenses will remain in the range of between 115 and 120 million for the full year 2024, which is consistent with our prior guidance. And we expect our cash investment for the full year of 2024 to remain in the range of between $15 and $20 million, which is consistent with our prior guidance. With a strong balance sheet and a focused strategy, we believe YMABS is well positioned to execute on our strategic missions and priorities and to support the delivery of multiple anticipated near-term milestones. This concludes the financial update, and I will turn the call back over to Mike.

Thank you for that overview, Pete.

Now let's open the line for questions. Operator?

Thank you. We will now be conducting a question and answer session. If you would like to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment, please, while we poll for questions. The first question is from Edser Daru from BMO Capital Markets. Please go ahead.

Great. Thanks for taking the question. One on Danielza and another on the GD2 SADA. So for Danielza, you could talk a little bit more about the price mix dynamic in the quarter. And is this something you expect to continue moving forward? And what are the potential offsets in the fourth quarter? And then on GD2 SADA, You have, you know, no dose-limiting tox, dose correlating to preclinical data. If you could talk through maybe the key criteria for dose selection for sort of the Part B of the study, thanks. For the antibody specifically, the dose for the antibody specifically, thanks.

Sure, Esther. Thank you very much for that. I'll pass the first question on regarding the price mix to Sue. and then bring it back for the protein soup.

Thanks, Mike. Thanks for the question. So we took an approximate $1.5 million charge in Q3 for Medicaid-related claims for both period and out of the period. And so due to that price mix, we saw a 5% decline in net revenues, even in spite of having a 5% increase in vials. And so with the adjustment, the sales would have been up 4% for both year over year and quarter over quarter.

Thank you, Sue.

So the second question you had was around the protein, the optimal protein dose on our GG2 SADA. So what we've done so far through the first six cohorts is we started at the 0.3 milligram per kilogram, escalated up to 3 milligram per kilogram, and have since backed that down to one milligram per kilogram, shortening the window and looking at an optimized window. So to move that into part B, for us it was mirroring more of the preclinical PK data that we saw, looking at the blood levels, understanding we want a dose near the nadir. And what we've seen so far with that is allowing us to then focus on the one milligram per kilogram and feel very confident that we're narrowing that down. So, Vinesh, anything additional to that?

Just to build on that, obviously, we need to evaluate the dosimetry in the tumor as well as in normal tissues. And, of course, the safety in all of this will contribute to the evaluation of the optimal dose and the dose interval.

Great.

Thank you.

Thank you, Arthur.

The next question is from Lee Watzek from Cantor. Please go ahead.

Hey, good morning. Thanks for taking our questions. I guess if you can comment on some of the swing factors for Q4 revenues as we're heading into the holidays, your confidence level of hitting that the lower end of the guide. And the second question is just for GD2 SELDA. You're looking at a number of histologies, so wondering if you can comment on the radio sensitivity of these tumor types.

All right. Thank you, Lee.

For the fourth quarter guidance, I'll pass you to Pete, and I'll allow Pete to expand on that.

Well, Lee, thanks for the question. With regards to the guidance, we feel very confident that we should land within the range of $87 to $95 million, we did highlight for you as part of the earnings call that we should most probably land in the lower half of that range. If you look at the third quarter results, although they were $18.5 million as reported, we did highlight for you that the cyclone sales did land in the fourth quarter So with the cyclone sales adjustment, with the Medicaid adjustment, and then also the NOBL or the timing of the NOBL licensing deal, we most probably would have landed actually based upon the consensus numbers just about where the consensus numbers were for the third quarter. So for the fourth quarter, we still anticipate a very strong quarter, and we anticipate to land somewhere in the lower half of basically the guidance range as we laid out for you guys between $87 and $95 million. Hopefully that helps you, Lee.

And Lee, your second question around the GD2 SADA and the radiosensitivity, I'll pass that on to Vinesh.

Thank you. So just to remind everybody the cancer that we have included in the 1001 study include osteosarcoma, melanoma, soft tissue sarcoma, small cell lung cancer. And in the latest cohort, we added adult neuroblastoma. It's too soon to say what we've seen in terms of early indicators of sensitivity to radiation. As you know, the GD2 expression levels is quite heterogeneous in these solid tumors. The variations within the tumor, as well as antigen density, hence the rationale to include also adult neuroblastoma patients. So as we get more data on the evaluation of the symmetry and responses will update the group here in terms of what we've seen in terms of radiation sensitivity.

Okay, great. Thank you.

The next question is from Alex Stranahan from Bank of America. Please go ahead.

Hey, guys. Thanks for taking our questions. Just two from us. First, with moving your headquarters early next year, curious to hear the latest on your approach to manufacturing and whether you'll be making additional investments here as your SATA assets progress through the clinic. And then on the new deal in Japan, maybe outline how you see the commercial rollout going there and sort of the incremental TAM that Japan represents for Danielsa. Thank you.

Sure. Thanks, Alex. Our philosophy on manufacturing hasn't changed. We're in a unique position with both Danielle's and our SADA platform that the way our current structure is, we're able to use contract manufacturing for our proteins, which allow us to, rather than invest in brick and mortar, allows us to invest in the drugs themselves. And similar on the SADA platform, we're able to use the same network that we have for our SADA protein constructs. and contract directly with isotope manufacturers for the production and caging of isotopes. So we're doing additional work with our proprietary chelators as we're looking to expand within the alpha and beta space as well as the PET that allow us then, rather than, again, investing in manufacturing, really invest in drug development. The second point, as we look at Japan, We've got a small clinical trial to do within Japan and that'll be limited to six patients to confirm similar to what we've done in the US in order to get that rolled out. So we expect to kick that off rather shortly and increase the overall ability to launch that product hopefully in the second half of 25 to early 26. So as we move forward on that, As we look at the total addressable market, Japan is a significant healthcare market, but overall, it is a much smaller market than the U.S., and we'd expect to see incremental from that, but not necessarily a very large expanse of our total addressable market.

Got it. Thanks. Thanks, Al.

The next question is from Justin Walsh from Jones Trading. Please go ahead.

Hi, thanks for taking the question. I'm curious what your thoughts are on the increasing numbers of players testing pre-targeting approaches. I'm specifically thinking about some pre-clinical data on another approach being tested by Roche and Aranomed that was at EANM, adding to the groups that we're already following. Do you think that this provides additional validation for or confidence in what you're already trying to accomplish with SADA?

That's a good question, Justin. I think as we look at this, any time you see more and more companies coming into it, it does validate what the theory is around providing maximum dose to the tumor, minimum off target, and more importantly, providing better logistics to get into shorter lived isotopes. So, you know, we welcome this from an intellectual point of view as well. The more smart people and smart companies you have working on this, the more likelihood you'll get more and more pre-targeting products out to the patients and into the clinic. And again, what's extremely important about that as well is leveraging the existing infrastructure to get more patients treated without having to go to specific theranostic suites. So we welcome that opportunity. I think there's a variety of methods in which to do this, and time will tell which is optimal, which is right. And there are always more than one right answer. So we wish the others much success as they move forward. And it really allows us then to focus on what we can do well and what we will do well for the patients and practitioners.

Great. Thanks for taking the question. Thanks, Justin.

The next question is from Mike Oates from Morgan Stanley. Please go ahead.

Hi, good morning. This is Rohit on for Mike. Thanks for taking our questions. Just going back to 3Q Danielle's sales, how much of the decline would you contribute to seasonality, competitors, and the ongoing clinical trials? And I think you mentioned something on a change in estimate for Medicaid claims for the quarter. Can you just elaborate on that? Thank you.

Sure. Thank you. Thank you very much. You know, I guess we'll start backwards on this, and I'll pass it over to Pete to talk a little bit about what the Medicare looks like and what the changes are there, and then we'll move over to Sue to talk a little bit about the volume and what we see as impacting that as well as potentially what the good news is in the way of volume.

So, good question. With regards to the Medicaid element of the sales mix for the U.S., The reality is the number of sites that we're selling into that have Medicaid 340K is continuing to increase a bit more relative to sites that have less of that presence in those sites. And so as we got into the third quarter, we had an adjustment that was associated with both in quarter as well as previous quarter coming into this. And so to that note, there was about a $1.5 million push down that we had to take in the quarter relative to that. So overall, we did report about 15.3 million. I think Stu alluded to this earlier. With the 1.5, we're at about 16.8. One thing that we did not really get into was there was also some timing related issues, specifically in shipments also. within quarter that slipped into the fourth quarter. That was about another $700,000. And so when you actually compare kind of where we were a year ago, third quarter at 16-1, with those adjustments, we would have landed somewhere around 17-5. And so actually our sales overall is kind of up. And that kind of correlates, as you saw, we did have volume increases for the quarter. You know, again, there were some timing related things that fell in quarter that impacted us, but for the most part, it continues to reinforce our confidence with regards to kind of where the markets are, where Danielsa is. So then I'll pass it over to Sue for a little bit more color here.

Okay. Thanks, Pete. Thanks, Mike, for the question. Yeah, I think obviously, you know, our mix continues to be about 80-20 with U.S. being about 80% of our volume. And we have on all indicators, key performance indicators, grown quarter over quarter in terms of the number of physicians treating, the number of patients with two or more patients. And notably, the majority of our sales is coming from high volume centers where our market share is higher than if you look at all centers together. And that, we believe, is really coming because of our new competitive campaign, which is enabling us to really talk about differentiating our core value in being able to still attain a complete response, even in heavily pre-treated patients, and even in patients who are no longer responding to or have developed antibodies to prior anti-GD2 therapy. So that is certainly how we're going after market share of unituxin. And we also, as we've mentioned, see volume in the fourth quarter coming from China due to the timing of that large shipment that Pete talked about.

Thanks Sue. Thanks Pete.

The next question is, pardon me, as a reminder to ask a question please press star 1. The next question is from Jeff Jones from Oppenheimer. Please go ahead.

Good morning, guys, and thanks for taking the question. Two from us, one on Danielza and one on SADA. With respect to cash runway, which you projected into 2027, can you highlight what studies and work is included there amongst Danielza and SADA? And then for the SADA platform specifically, When might we hear more detail around future plans, targets, target selection, and indication?

Thanks.

Oh, thank you, Jeff. I'll pass the first part of your question on to Pete for cash runway and what we have planned and kind of how we're looking at that.

Yeah, Jeff, good question. Previous quarters, we communicated that we have runway into 2027. We've reiterated that as part of this quarter as well. Again, I would first start with our cash investment or burn for this year on a net basis relative to kind of where we set out guidance. So our guidance is $15 to $20 million of investment this year over and above the proceeds cash inflows from Danielza. What we're seeing specifically to date and we issued that as part of this earnings releases. We're slightly over $10 million a year to date on that number. We do have some favorable things coming in now as part of the fourth quarter. We mentioned the noble licensing deal, that $2 million is coming in alongside some other things. So we're well on track to the lower end of that 15 to $20 million range is kind of what we're anticipating for this year. That should land us kind of in the low 60s, most probably somewhere 60 to 65. I would skew more to the 65 number. And then kind of as we go forward, what are anticipated views around both investment and return on Danielsa was that Danielsa would continue to see some mild growth, call it single digits to maybe a low double-digit number. In either view, we get good cash flows off of Danielsa moving forward over the next number of years. And then on the investment side of the equation, we anticipated that we would be investing in new SADA programs at least one to two every year. So that was kind of the thought process as we laid it out. As is the case, Jeff, most companies are going through kind of a revised operating plan cycle at this time of year. When we issue our 10Ks in March, we'll issue new guidance for not only 2025, but also give you guys an update as to our thoughts around investment moving forward. So hopefully that helps you.

Yeah, and Jeff, as a follow-up to the second part of the question, we're actually right now in that process of evaluating a multitude of targets and narrowing them down to targets that really – fit what we're doing here at YMAPS. So we're in that process, and I would say in the early part of 2025, most likely first quarter, you'll see a revised priority list as well as specific timelines and what exactly we are going to be targeting moving forward. And as Pete discussed, we have plans to invest in several targets and bring several programs per year into the clinic. So stay tuned for that, but that will happen in early 2025. Great. Appreciate that.

Thanks, guys.

Absolutely. Thank you.

The next question is from David Nearingarten from Wedbush Securities. Please go ahead.

Thanks for taking my question. I was just wondering if you could tell us on your the dose escalation and kind of, um, um, push or pull back. I'm going to call it back to one milligram. Is there any, um, sorry, was there any, um, differences in tumor types that drove that or tumor burden or was it just timing and PK? Like, I don't know if you could walk us through without, you know, giving us the data to really, um, um, you know, kind of what was, what you were seeing that, um, drove you to decide or look at the dose level. Thanks.

Yeah, David, that was a great question. We'll give you much more of that detail once we release it, but I'll give you the top line on this. We've talked about this in the past. What we need to do with the radiopharmaceuticals in a pre-targeting is paint the tumor and to cover those receptors without putting so much in the blood that were taking a long time to clear it out. So we know the disassembly of SADA is concentration dependent. So when we modeled the preclinical data based on the mouse model, one milligram was the target based on that. We had the flexibility to go up to 10 times higher than that and started at one third of that. But the reality was we started at one third looking at it from a safety perspective, brought it through the one milligram and then 3x that at the 3 milligrams. And the PK was modeling what we saw in the preclinical. So it made sense for us to bring it back to that target level rather than go higher and extend the time in which we would wait for the isotope. So now it's just fine tuning that back. And it had nothing to do with tumor types. It had nothing to do with uptake. It had nothing to do with any of that. It was more of We felt that being that the PK levels were modeling that of the preclinical data, that we narrow that down as a variable and bring it back into that range and start shortening the window, again, changing one variable at a time. So we feel very good about where that is. And again, it had nothing to do with any toxicity or anything else. It was really feeling that we had enough protein to paint the tumor and clear it quickly enough from the bloodstream.

Got it. Thanks. Thanks, David.

The next question is from Nicole Germino from Truist Securities. Please go ahead.

Good morning. Thanks for taking my question. I have two on data. The first one, can you just talk a little bit more about the dosimetry and which organs do you expect the drug to accumulate and more, and what are the acceptable mutation levels in kidney and liver?

Yeah, Nicole, that's a great question. I think when we look at this, understanding that both the SADA as well as the lutetium dota are renally eliminated, we would expect to see, as far as off-tumor, for the kidneys and the bladder to be the highest impact to any organ. The second would be any kind of liver uptake or bone marrow. We're evaluating all of that as part of the clinical trial since, again, this is the first in human. But I'm not, right now, don't have any data to share on those and what they look like. And, Vinesh, I don't know if there's anything from your side that you want to discuss as what our limits we're looking at as far as what we're trying to maintain below.

Yes. In addition to what you just said, what we're expecting, the symmetry absorbed dose in tumor And, of course, off-tumor tissues, one thing we can, and we've already shared this with you in terms of the safety margins. So far, we've not seen any early indications of any safety issues, no dose-limiting toxicities or treatment-related serious adverse events. But further evaluation will go, and we'll share with you more results as we get through soon.

Okay, great. And then one quick question on your targets. Can you elaborate more on your target selection strategy and what are the parameters for how you're choosing your target priorities?

Yeah, we're working through that right now. We'll lay that out as part of the total strategy. It's not something we're ready to disclose at this point as we're walking through the list, but we are looking at many receptor-modulated diseases. We're looking at unmet need. as well as commercial potential. So there is a significant amount of criteria we're putting into this, and this will be a living document for us. As we move forward and bring targets into the clinic, we'll be looking at the next five to ten targets, how they are positioned both clinically and commercially at that point in time, and can reprioritize as we move forward. So there are several criteria, and we'll outline that as we bring this entire strategy forward.

Okay, thank you.

Thank you.

This concludes the question and answer session. I would like to turn the floor back over to Mike Rossi for closing comments.

Great. Thank you, everyone, for joining us today to discuss our third quarter results and continued progress. We have a strong financial foundation and continue to believe we are uniquely positioned for future growth while advancing the clinical development of our differentiated radioimmune therapy platform, SataPRIT, to potentially deliver better and safer therapeutic options in the treatment of a number of serious diseases with unmet needs. We look forward to seeing many of you at upcoming investor meetings and medical meetings throughout the winter. If we didn't get to your question, you have additional questions, we're happy to schedule time with individual investors and answer those questions at that point in time. Thank you and have a great day.

This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
