Speaker 2

Thanks, Nicole, and thank you all for joining us today. As you will have seen, we have shared some very exciting news items earlier this morning. But to begin with, I'd like to focus on key business updates for the quarter. Starting with our commercial performance, ZINLANTA continued its return to sequential growth with revenues of $17,800,000 in Q1. This represents a 7% increase over the Q4 of 2023.

Speaker 2

Importantly, we saw continued growth both in the community and in academic centers despite the intensified competitive landscape. Turning next to our pipeline, we have made significant progress. Last month, we announced that our LOTUS-seven study of ZEMMATA, in combination with bispecifics, successfully cleared the final dosing cohort in both arms with no dose limiting toxicities, no iCAMS and either no or low grade levels of CRS. We are now dose expanding at 120 and 150 micrograms per kilogram in the ZENLONTA plus glofitamab combination arm in second line plus DLBCL. Today, we are delighted to share for the first time encouraging initial data recently presented from the University of Miami's Phase II investigator initiated trial of ZENLONTA in relapsed refractory marginal zone lymphoma.

Speaker 2

Based on initial results from the first 15 evaluable patients, 13 achieved a complete response and 1 achieved a partial response with all patients maintaining response at the time of data cutoff. Moving to ADCT-six zero one, our novel axial targeting ADC, we began enrolling pancreatic cancer patients and continue to enroll sarcoma patients and we are in the process of optimizing the dose and schedule. Lastly, we shared a comprehensive update on our novel exotecan based solid tumor platform, including early preclinical data on our 4 preclinical ADC candidates for the first time at our recent research investor event. Finally, in terms of a corporate update, we maintained our disciplined capital allocation strategy and decreased operating expenses in Q1 by 16% year over year on a non GAAP basis. This in turn enabled us to manage our cash burn so that we ended the Q1 with cash of $234,300,000 On top of this, we have just announced today that we have priced an underwritten offering to raise $105,000,000 in gross proceeds.

Speaker 2

The offering at the closing price per share on Friday included common shares and pre funded warrants and is expected to close on May 8. We expect this will extend our cash runway into mid-twenty 26 and provide the company with enhanced financial flexibility to execute our strategy. Given our strength in balance sheet, I would like to remind everyone of the strategy we are pursuing, which we believe will unlock the tremendous value we see in the company. Our first pillar and primary focus remains hematology. Within this, we have a de risked asset in ZELONTA, the key product in our prioritized portfolio, which we expect to carry the company through to profitability.

Speaker 2

We are deploying the majority of our capital to the Xelanta franchise to commercialize our existing third line plus DLBCL indication and to pursue the substantially larger potential opportunity in earlier lines of DLBCL therapy and indolent lymphomas such as marginal zone lymphoma. We believe these potential opportunities will help expand the ZENONTA franchise and have the potential to generate annual peak sales in excess of $500,000,000 The second pillar of our strategy is grounded in our emerging solid tumor pipeline. ADCT-six zero one is our most advanced asset. Behind this, we see the potential to advance a broad portfolio of differentiated ADCs against solid tumor targets of interest, driven by our novel exotecan based platform. I'd like to expand now on the substantially larger potential opportunity for ZEMONTA in earlier lines of DLBCL therapy and indolent lymphomas.

Speaker 2

Pending the results of the LOTUS-five and LOTUS-seven studies, our goal is to expand usage of ZERMONTA into second line plus DLBCL. As a reminder, LOTUS-five is our confirmatory Phase 3 study of ZEMONTA in combination with rituximab. Here, we remain on track and expect to complete enrollment by the end of this year with the potential for a headline readout by the end of 2025. If positive, we believe this trial will lead to full approval for ZENOLTA and expand our indication into second line plus DLBCL in combination with rituximab potentially as early as the end of 2026. VOTIS 7 is our Phase 1b trial of XERMONTA in combination with bispecifics.

Speaker 2

We are encouraged by the initial safety and tolerability profile as well as the observed anti tumor activity amongst the majority of patients in Part 1 of the dose escalation. We are now enrolling in Part 2 dose expansion with ZEMATA plus glofitamab in second line plus DLBCL and expect to complete enrollment and plan to share additional efficacy and safety data before year end. We also see the potential to expand the use of ZENONTA into the 2nd line plus settings of follicular lymphoma and marginal cell lymphoma based on initial data from investigator initiated trials at the University of Miami. Today, I want to focus on the marginal zone lymphoma data that was shared this past weekend at the Lymphoma Research Foundation's 2024 Marginal Zone Lymphoma Scientific Workshop by the trial's lead investigator, Doctor. Isidore Losos at the University of Miami.

Speaker 2

Relapsedrefractory MZL represents an unmet need. Based on publicly available incidence data, there are an estimated 3000 to 4000 second line plus MZL patients who are drug treated in the U. S. Unmet medical need remains in relapsedrefractory MZL, less than 30% CR for second line plus approved or NCCN preferred treatments. At present, there are 2 FDA approved regimens and several other preferred regimens for the treatment of MZL in second line plus included in NCCN guidelines.

Speaker 2

Complete response rates are modest and sample sizes in the study supporting this data are relatively small. As complete response rates are a strong predictor of time related outcomes in MZL, clinicians continue to seek novel agents with higher and durable CR rates, a manageable safety profile and a fixed duration of treatment. The University of Miami is leading a multicenter Phase 2 IIT study in ZEMONTA as a single agent fixed duration regimen to treat 50 relapsedrefractory MZL patients. Initial data from the first 15 evaluable patients showed 13 achieved a complete response and 1 achieved a partial response. According to the lead investigator, ZINNALTA was generally well tolerated and safety was consistent with a known profile.

Speaker 2

There are 2 sites currently enrolling, University of Miami and City of Hope, and the lead investigator is currently expanding to 5 sites to accelerate trial enrollment. As soon as we have sufficient data, assuming it remains positive, we plan to potentially pursue our regulatory pathway and compendia strategy in parallel. In terms of the opportunity based on our analysis, we believe the total addressable Second Life Plus NPL patient population has a potential peak market opportunity of approximately $500,000,000 valued at ZYNOLTA price and an expected average number of cycles. If successful, it means every 10% of market share captured represents $50,000,000 in incremental annual peak sales opportunity. While still early in the Phase 2 IIT, if this trial continues to yield similar results, the potential opportunity to expand into MZL could contribute to the overall Zenitha growth strategy in NHL.

Speaker 2

The current standard of care in MZL includes CD20 based regimens across all lines in addition to BTK inhibitors at second line MZL. The data used for FDA approvals and inclusion in NCCN guidelines were based on either single arm studies or a subset of larger indolent NHL studies and offer modest CR rates, which are below 30%. Per the study protocol, all patients included must have failed 1 or more lines of systemic therapy, including at least 1 anti CD20 antibody. Under the protocol, patients receive a fixed duration of treatment of 6 cycles of XENONTA across 18 weeks. The primary endpoint is CR rate at 6 12 months as patients will be followed for up to 3 years with progression free survival and overall survival measured at 24 months.

Speaker 2

The predetermined futility threshold for efficacy was set at 31% CR rate. Looking at the baseline characteristics of the patients enrolled so far in the study, there are a few things I want to point out. We believe this initial group of patients is representative of the overall MCL population, including MCL subtypes. In addition, of the patients treated with XENONTA so far, 10 of the 15 were Stage 4 MCL patients with 8 of the 15 designated as POD24, meaning they progress within 24 months of initial treatment, a group that is typically harder to treat. The median prior lines of therapy is 2 ranging from 1 to 4, and as you can see on the right side of the slide, included multiple currently available systemic treatments.

Speaker 2

As shared by Doctor. Losos at the Lymphoma Research Foundation's 2024 Marginal Zone Lymphoma Scientific Workshop on May 4. These initial results showed 13 out of 15 patients achieved a CR with 1 additional patient achieving a PR. Of the 13 CRs, 9 were achieved after 2 cycles. In addition, all patients achieving responses had maintained them as of the data cutoff, with the longest responder reaching approximately 20 months.

Speaker 2

And from an initial safety perspective, per the lead investigator in this study, ZILMTO was generally well tolerated and consistent with a known safety profile. One patient discontinued after cycle 2, a second patient discontinued after cycle 4 due to a toxicity which fully resolved upon discontinuation of treatment. Both of these patients remain in CR at 10 and 6 months respectively. Based on this initial data from University of Miami's Phase 2 trial evaluating ZYNOLTA in relapsed refractory MZL, we are encouraged by the potential opportunity in the second line prosthetic for patients with this rare disease. Moving on to LOTUS-seven, we are sharing here additional safety data from the Part 1 dose escalation portion of the study.

Speaker 2

The important takeaways are that the majority of CRS events were Grade 1 and that no CRS greater than Grade 2 is observed. Those patients who have experienced a grade 2 CRS were managed with no requirement for ICU management or pressers. On the left hand side, you will see that the overall CRS rate with glofitamab was 33%, which is the combination of focus for Part 2 of this study. Important to note, the current glofitamab label in third line plus DLBCL includes a 70% CRS rate, including some higher grade events. We believe that dosing with ZYNOLTA 1 week prior to glofitamab may be debulking the tumor.

Speaker 2

Turning to our research platform, we hosted a virtual investor research event on April 9, which provided a comprehensive overview of our solid tumor research strategy, our novel exotecan based platform and our 4 lead ADC candidates. Our focus is on advancing differentiated ADC candidates against prostate, non small cell lung cancer, colorectal, endometrial and ovarian cancers. For each tumor type, the combination of incidence and 5 year survival offers large potential opportunities and indicates that better treatment options are needed. Furthermore, in each case, chemotherapy remains a key part of the treatment armamentarium. Our 4 lead ADC targets are NaPi2b, claudan6, PSMA and ASCT2.

Speaker 2

We believe each offers the potential to improve the standard of care for cancer patients and each utilizes our novel exotecan based platform. Preclinical work suggests that our 4 lead candidates each have a high therapeutic index, reflecting the proprietary design of the ADC. In terms of stage, our NaV2b and claudin6 ADCs are in IND enabling studies, and we are pleased to share exciting early data on these at AACR last month. Our PSMA and ASCT2 ADCs are in the drug candidate selection stage, which we expect to complete this year. Looking ahead, we plan to move forward with 1 candidate to IND and to seek research collaborations to advance a broad portfolio.

Speaker 2

Given the unmet medical need coupled with the market opportunity, a successful outcome for 1 or more of our early research programs has the potential to transform the lives of patients and create significant value in the future. With that, I would like to turn the call over to Pepe.

Speaker 3

Thank you, Amit. Before I discuss today's financing, I will take you through a brief summary of our Q1 results. As a reminder, we are now reporting our results under U. S. GAAP.

Speaker 3

We became a U. S. Domestic fighter as of January 1, 2024. Starting with our balance sheet, March 31, we had cash and cash equivalents approximately $234,300,000 Moving to the P and L, as you already heard, Reynolda net sales were $17,800,000 in the quarter, a decrease of 6% versus prior year, primarily driven by higher gross net deductions and lower volume, partially offset by higher gross price. On a sequential basis, In Lonza net sales grew 7% versus the Q4 of 2020.

Speaker 3

Our total operating expenses on a non GAAP basis, which excludes stock based compensation, were down 16% compared to the Q1 of last year. This mainly reflected our focus on driving operating efficiencies together with reduced R and D expenditures due to focused investment in our clinical studies and lower selling and marketing expense. For 2024, we will continue to take a very disciplined approach to our capital. You can find the reconciliation of GAAP measures to non GAAP measures in the companion financial tables of the press release issued earlier today and in the appendix of this presentation. Moving to the bottom of the P and L.

Speaker 3

GAAP basis, we reported a net loss $46,600,000 for the quarter or $0.56 per basic and diluted share. On a non GAAP basis, adjusted net loss was $31,100,000 adjusted net loss of 0.38 dollars per basic and diluted share. The decrease in both reported and adjusted net loss for the Q1 of 2023 was primarily due to lower operating expenses. Today, we have announced the pricing of a registered direct offering, which included prefunded warrants. We expect to close by May 8 and the offering is expected to raise approximately $105,000,000 of gross proceeds.

Speaker 3

We have been delighted by the response from our range of high quality institutional investors and we expect to proceed to extend our cash runway into the middle of 2026. By strengthening our balance sheet, we believe we are now better financed to pursue our corporate strategy. As a reminder, hematology continues to be the primary focus of our capital allocation and within this, our key objective is to create value by expanding the use of XENLONTA beyond the current indication. We expect to achieve this by fully supporting our commercialization effort in the U. S.

Speaker 3

Directly and through our partnership ex U. S. And by investing behind potential expansion into early lines of DLBCL and indolent lymph nodes. In solid tumors, our aim is to pursue multiple ADC candidates in parallel and increase our shots on goal, mainly through our novel exotecan based research platform. We will determine on a case by case basis whether we wish to progress candidates internally or seek partner in order to share the development of financial risk.

Speaker 3

As Amit mentioned earlier, we intend to take at least one candidate forward to IND and the new funds raised give us security freedom to do so. My final slide highlights the multiple potential value driving milestones, which we expect in the coming year. Importantly, we have delivered on our promises to date in 2023 with positive updates for ZYNOLTA in the LODO-seven study and MCL IAP clinical trial. With the initiation of dosing of ABCD-six zero one in pancreatic cancer and with the disclosure of our existing new research platform at our virtual investor research bank. In the second half of this year, we have multiple potential value generating catalysts including expected completion of enrollment in LOTUS-five, initial efficacy and safety data from LOTUS-seven Part 2 expansion and initial read of AAVC-six zero one in XL in both sarcoma and pancreatic cancer.

Speaker 3

With that, I will turn the call back to Amit.

Speaker 2

Thanks Pepe. To conclude, my team and I are very proud of our performance in the Q1 of 2024. We achieved another quarter of sequential growth with ZINNALTA. We delivered against each of the planned key research and development milestones, and we maintained our disciplined approach to capital allocation. Looking ahead with a strengthened balance sheet and enhanced financial flexibility to execute our strategy, I am confident that ADC Therapeutics is well positioned to drive value creation for all of our stakeholders.

Speaker 2

With that, operator, could you please begin the Q and A session?

Speaker 3

Sorry, operator, we cannot hear the question.

Speaker 4

Thank you. One moment. The first question will be from Kelly Shi from Jefferies. Your line is open.

Speaker 5

Hi, good morning. This is Yun for Kelly and thanks very much for taking the question and congratulations on the margin is only lymphoma data. I believe you reported very positive data from the follicular lymphoma program where investigators initiated study at ASH. And so can you remind us your plan for follicular lymphoma and comparing to marginal zone lymphoma? And which one do you think could potentially be maybe reach the potential or enter sponsored study first?

Speaker 5

And have you received any feedback in terms of the safety considering that it's an indolent lymphoma patient? Thank you.

Speaker 2

Yes. No, thanks for the question. I think you're right to say that we were excited to share data at in an oral presentation last ASH on the relapsed refractory follicular lymphoma population, which showed that the combinations in Lonza plus rituximab had an overall response rate of 96% and a CR rate of 85% with a manageable safety tolerability profile. So I think that was really encouraging data. Of course, now seeing the marginals on lymphoma data and another end of lymphoma with again high overall response rate, high CRH and again a manageable safety profile.

Speaker 2

We're really encouraged. Both of these trials have been expanded. So the follicular lymphoma patient study will now be 100 patients, Marginal Zone will be 50 patients, both are multicenter studies as well. And with both of them, we plan to pursue both a regulatory strategy as well as a compendia strategy in parallel based on the outcome of the data. The one thing to note about follicular data that's important is that it's really just going after the high risk patient population.

Speaker 2

We know that when you go after all comers in follicular lymphoma, there is a precedence for randomized Phase 3 studies with long follow-up. We're focused on a narrower population, which is a high risk population, most of which were POD24. And we think that if the data looks good, there may be a faster pathway potentially, either through a regulatory pathway or through guidelines in that more narrow patient population. MZL is probably even more straightforward because if you look at the majority of or if you look at everything that's been approved either by the FDA or in guidelines, they've been approved based on either single arm studies or subsets of larger randomized studies in indolent lymphoma studies and typically with somewhere between 40 to 70 patients. So we think the 50 patient study we're running is an appropriate size.

Speaker 2

And based on the data maturity from this study, we again will pursue your guidelines and a regulatory pathway in parallel. So that I would say is the even more straightforward pathway because there's so much proximase in MZL. But we also think just given the strength of the data have a really interesting opportunity in follicular as well.

Speaker 5

Great. Thank you.

Speaker 4

Thank you. And our next question will come from Michael Schmidt from Guggenheim. Your line is open.

Speaker 6

Hey, guys. Thanks for taking my questions. And yes, super interesting update here at MCL, obviously. I think you said all of the patients are still in response. Could you just help us contextualize the duration a little bit?

Speaker 6

What do we know about the duration of clinical benefit for other drugs in MCL and how does it compare to that? And then, yes, I think you did have this one patient discontinued due to a toxicity. Can you just comment on what that was? And then I had a follow-up. Thanks.

Speaker 2

Yes. Thanks, Michael. We're yes, as you said, we're really encouraged by the data as well. And also, in MCL confirming what we've seen in follicular and what we've seen in other areas, the safety profile has been really good. Haven't seen any new safety signals in any of these studies.

Speaker 2

So that's been encouraging. But I'm going to turn it to Mohamad to talk about both the duration that's seen in other treatments and what we would want to see here.

Speaker 3

Yes. Thanks, Michael. First, I want

Speaker 7

to highlight that one of the patients in CR already reached 20 months. Many of the patients have currently are more than 10 months and all are ongoing, you are correct, at the time of Danica. What has been reported in the literature, it's smaller trials and range between possibly 15 months 18 months. Those are the kind of PFX that have been reported or their ability within either single agents or in combination. So if the data maintains the way it is and responses are continuing for all the patients that we have seen of HER-thirteen, HER-fifteen CR-1PR, we believe we'll be in a very good place in terms of the ARGX-eighteen.

Speaker 7

But again, for our durability, it's a little bit too early to talk about.

Speaker 2

Yes. And then, Michael, your second question was around the one patient with toxicity. We don't have more details. The investigators planning, as the sample size increases and the duration and follow-up increases to do a much bigger presentation at a more major medical Congress where he will share all the data. He doesn't want to compromise that.

Speaker 2

So what we know from the investigator is one patient had a toxicity discontinued after cycle 4, that patient was already in CR. Once the patient was discontinued, the toxicity fully resolved and that that patient still remains in CR. Now that patient is 6 months out. So that's what we know. The other thing we understand from the investigators, everything they've seen across all 15 patients, the safety profile is consistent with the known safety profile of ZEMANTA.

Speaker 6

Great. Awesome. Yes, super interesting. And then a question on LOTUS-seven. I know you had some really early Phase 1 data at AACR.

Speaker 6

And I just wanted to know if you could provide some visibility in the next update. I think you have another look at data in the second half of this year and then more in the first half of next year as well.

Speaker 8

Yes. So,

Speaker 2

we are now in Part 2 dose expansion right now. We were quite pleased, I think, with the dose escalation and how smoothly it went and now we're in dose expansion. Looking at ZENLONTA plus gofitamab in second line plus DLBCL patients, we're looking at it at 2 different doses of ZENLONTA. It's 150 microgram per kilogram dose as well as 120 microgram per kilogram dose, both in combination with the full doses of flafitamab. We are expected to complete the enrollment of roughly 20 patients in each of those dosing cohorts by the end of this year.

Speaker 2

And then we will share the safety and efficacy data that's available for all evaluable patients. What we mean by that is patients that have had at least a 12 week scan because obviously any responses we want to make sure are confirmed. So that will be likely a subset of those 40 patients that are actually available at that time. We will share all the data that's available by the end of the year and then provide an even more comprehensive update in the first half of next year when we have data from all 40 patients, including longer follow-up.

Speaker 6

Great. Super helpful. And then lastly on LOTUS-five, it sounds like you're well on track to complete enrolling here later this year. And just curious if you had any additional visibility on the

Speaker 2

event rates as they're coming in and sort of

Speaker 6

the timing of the primary analysis? Thanks so much.

Speaker 2

Yes. I mean, as you said, and I'll turn it to Mohamad to comment further, but we're on track to complete the study. The enrollment pace has picked up quite a bit over the course of this past year and even this year in particular has picked up quite a bit. So we're confident in completing the enrollment of the study this year. It's an events driven trial, so you can never predict the when it's going to exactly read out.

Speaker 2

But based on our current thinking, we believe it may read out as soon as the end of 2025, which if that's the case and it's positive, could lead to an approval as soon as the end of 2026. But Mohammad, do you want to comment more on the enrollment and what you're seeing with LOTUS-five? Yes. We're very pleased with the current enrollment.

Speaker 7

It picked up strongly during 2023 2025 release. So we are still in I believe that we will be able to enroll the study this year. Things are doing very well. Also, we have a D and C that meets regularly that have cleared the study multiple times with no changes. So that's a very positive sign.

Speaker 7

In addition, I would like to say that the events are being reviewed by independent center review. So that's another very key element for us to make sure that those are confirmed and then completely independent. As you know, we're blinded, but it's an event driven study and it's take until next year, that's a positive thing and hopefully that will remain the case. So that's pretty much all about Woodstock at the moment.

Speaker 2

Yes, I think all on track with Woodstock. We feel good about the progress and we're well on track to complete it this year.

Speaker 3

Great. Well, thanks

Speaker 6

so much. Congrats on the update today.

Speaker 2

Thank you.

Speaker 6

Thank you.

Speaker 4

Thank you. And our next question will come from Gregory Renza from RBC Capital Markets. Your line is now open.

Speaker 8

Hi. This is Saputo on for Greg. Thank you so much for taking our questions and congrats on the progress. I have questions on the competitive dynamics from CD20 bispecific. Number 1, has the impact been fully realized the impact of the competition from CCD-twenty bispecifics to be on to London?

Speaker 8

Has it been fully realized in the 3rd life setting? And now they Roche recently announced that the trial in the second line hit the primary endpoint and could potentially be ahead of the Lantus combination from LOTUS-five. I'm just curious how should we think about the competition from that the bisecte-twenty bispecific combo to LOTUS-five? Thank you so much.

Speaker 2

Yes. That's a great question. The bispecifics both of the approved bispecifics in the 3rd line plus DLBCL setting are definitely getting uptake, primarily in the academic center. We see much more limited use in the community. So in the academic center, there is quite a bit of use of bispecifics post CAR T.

Speaker 2

I think importantly, we still have seen some modest growth though in the academic centers overall in our volume when you look at Q4 to Q1. What that's been driven with is, while you have some lower level of depth in some centers that we're using Xelapa quite a bit in that setting, we've actually seen a higher amount of breadth of centers and academic centers that are using their product. And so, in essence, we've been able to basically compensate for a lot of that competitive impact, although it's real. I mean, biostatistics are definitely being used quite a bit. And you can see it in their growth rates a lot in that third line plus post CAR T T in the academic setting.

Speaker 2

So we've felt the competitive impact. I think importantly though, we've been able to largely academic center and we see continued growth in the community as well. So, we think our strategy is working. In terms of the data around the Golcitimab plus Gemoct combination, we'll have to look. We'll have to wait and see the data.

Speaker 2

Obviously, it hasn't been published. They give a top line result. I mean, one thing of note, I think, is just that they said that the I think that we'll have to pay attention to is what's the toxicity profile. We don't know. But obviously using systemic chemo with a bispecific, you want to see what the toxicity profile looks like.

Speaker 2

I think there we feel quite confident, I think, in our combinations both of ZENLANTO plus rituximab as well as ZENLANTO plus gilfidumab given the toxicity profiles we've seen there. So I think as we move into 2nd line, it's important to have strong efficacy and a manageable safety tolerability profile. We feel confident in both of our approaches.

Speaker 1

I don't have much to add, Ami. Again, we're excited to see the STARGLOW data that will be out at EHA. And as Amit said, we've been able to hold share pretty much in the academic centers. We see that despite the bispecifics, we have strong advocacy in the academic centers. And what we also hear is that these advocates recommend Enelata to the community treaters, which is critical.

Speaker 1

Once we see the data from LOTUS-five, the briefing is that, rituximab is probably one of the most commonly used agents out there with a lot of familiarity. So between LOTUS V and LOTUS 7, we offer great optionality with Simonta.

Speaker 2

Yes. It's a really, really important point that Christian just made. One of the most predominant uses, we know that CAR T is only used in about 20% of patients' 2nd line, really in the academic center. The majority of patients in academic centers are getting it. In the community though, R based chemo regimens are very, very commonly used.

Speaker 2

So we think an R based ADC approach is going to fit really well there.

Speaker 8

Okay. Thank you so much.

Speaker 4

Thank you. And our next question will come from Brian Chiang from JPMorgan. Your line is open.

Speaker 9

Hey guys, thanks for taking our question this morning. Maybe just the first question on LOTUS-seven. Can you talk a little bit more about the strategy beyond those expansion in LOTUS-seven? Will there be a need to run a larger second line pivotal study to get you officially move into the bispecific move in with the bispecific combo? And if you ask, how do you think about the study design and the timing?

Speaker 9

I have a follow-up. Thank you.

Speaker 2

Okay. Yes. Thanks, Brian. Great question. I'm going to hand it to Mohammed to answer the question on LADO-seven.

Speaker 3

Yes. Thanks, Brian. This is

a split wise approach. First, we'd like to see how the efficacy in the combination second line plus looks like and how it compares in the competitive environment. And definitely, we are looking to see how the safety profile is looking like. We're very pleased that we cleared all doses and see that. When we get to that point with the 2 doses that we're expanding, if the data persists, we're definitely planning to have a conversation with the regulators about the possibility of a Phase III approval there.

At that time, we will see what the comparator arm would be. However, there could be investigator risk choice, as you I'm sure you're aware of because there are multiple agents and many things could be available at that time. But of course, it's going to be a data driven approach. And the conversation with the agency is going to tell us more about that.

Speaker 3

Yes. Thanks for the question, Ryan. So, this year, ZINLONTA, we'll be able to pay for all the direct commercialization effort. That includes all the sales force, MSL, the A and P that we invest in the drug, the IAPs that we are having executing. And on top of that, obviously, cost of goods and products and what sort of.

Speaker 3

So that it doesn't what it doesn't include is the pipeline. So our LOTUS-five and seven trial and corporate G and A. That is not included.

Speaker 4
