speaker
Dr. Fred Vose
Interim Chief Executive Officer and President

Thank you, Sarah, and welcome to the I-Advanced second quarter and first half 2025 conference call. We are more than a year into our U.S. launch of Antagni for advanced melanoma, the first FDA-approved TIL cell therapy. Adoption continues to grow, and for the first time, we surpassed more than 100 patients treated in a single quarter. We're also excited about our first real-world data set for Antagni monotherapy in a commercial setting. Topline results showed a nearly 49% response rate among 41 patients, 23 patients treated in third-line or earlier treatment settings, and approximately 61% response rate, all from patients treated in accordance with their label. We look forward to sharing more detailed real-world data at an upcoming medical meeting. Another important growth driver for Ampagni is onboarding large community practices to join our ATC network. We plan to begin treating patients from these practices in the fourth quarter of this year. Patients in the community are generally earlier in their melanoma treatment journey, and we expect that the higher response rates observed in our real-world data set will also be relevant to these patients. Our commercial business is complemented by an exciting pipeline led by our programs to extend the Lifolucil franchise in the new treatment settings and solid tumor types, as well as next-generation approaches. We remain on track for multiple clinical milestones in the second half of this year, including updated data from our registrational trial of Lifolucil monotherapy, previously treated advanced non-small cell lung cancer, clinical data for lipoleucine monotherapy and endometrial cancer, and for IV4001, our next generation PD-1 inactivated till cell therapy. Today I will cover financial results at a high level, focusing on revenue, expenses, cash runway, and the expected cost savings from our strategic restructuring. I'll begin with revenue and gross margins. In the second quarter, we reported $60 million in total revenue, a 22% growth over the prior quarter of this year. Total revenue included approximately $54 million from tagging infusions and approximately $6 million from ProLuca. Based on current growth dynamics and with approximately $109 million in total revenue for the first half of 2025, we are reiterating our full year 2025 revenue guidance of $250 to $300 million, inclusive of sales from Ampagni in the U.S. and ProLucan globally. We contain a strong demand for Ampagni and the potential to achieve U.S. peak sales of $1 billion or more. There's also a significant opportunity to add to the revenue potential in the international markets. Gross margin was 31%, excluding non-cash items such as intangible amortization, stock-based compensation, and reserves primarily for excess ProLucan inventory. Our recent restructuring is expected to improve gross margins in the near term to reduce cost of sales. Gross margins are also expected to increase significantly through near-term optimization of manufacturing capacity utilization over the next several years. In summary, we're focused on improving our profitability and are pleased with the strong momentum from our U.S. commercial business. Transitioning to the second quarter of 2025 expenses. Total operating expenses were approximately $117 million, compared to approximately $102 million in the prior year period. This increase was primarily related to higher headcount and related costs, and costs for clinical trials and marketing and advertising support for AMTAGME, partially offset by reductions in stock-based compensation. After experiencing a tremendous period of organizational growth in 2023 and 2024, We are fully committed to streamlining expenses and optimizing business performance through a strategic restructuring announced today. This restructuring includes a workforce reduction of approximately 19% in the third quarter of 2025 and will generate more than $100 million in annual cost savings starting in the fourth quarter of 2025. As I mentioned earlier, in addition to significantly reducing expenses, this restructuring We'll also significantly reduce our cost of sales and increase gross margins on an ongoing basis. I would like to extend our heartfelt appreciation and best wishes to the employees impacted by the reduction in workforce. Realigning our operating plan and cost structure involves some difficult but necessary decisions to ensure financial discipline while continuing to invest in our commercial launch success. Notably, our registrational and early phase programs remain on track, and no significant changes to our product pipeline are expected. Our net cash burn is significantly reduced over our prior forecast. For the next four quarters through the second quarter of 2025, net cash burn is expected to be less than $245 million, excluding one-time charges of less than $6 million associated with the third quarter strategic restructuring. We will continue to optimize and refine our cost structure through operational excellence initiatives over the next two to three quarters, And importantly, we expect ongoing reductions in expenses and improvements in cost of sales. Our current cash position of approximately $307 million in anticipated product revenue, including cost savings from the strategic restructuring, are expected to be sufficient to fund current and planned operations into the fourth quarter of 2026. I am happy to go into more detail during the Q&A. Notably, we are excited to welcome our new Chief Financial Officer, Corleen Roche, who joined our team this week. We look forward to Corleen covering the financial results in detail from next quarter onwards, and she's available for today's Q&A session. I will now turn the call over to Dan Kirby, Chief Commercial Officer, for a detailed update on our commercial launch and our XOS regulatory milestones.

speaker
Dan Kirby
Chief Commercial Officer

Thanks, Fred. I'd like to build on the earlier revenue discussion by highlighting individual product drivers for Antagni and ProLucan. I'll also provide an update across our three key focus areas to drive U.S. launch performance, as well as our strategy for MTAGV outside of the United States. Product revenue from U.S. MTAGV sales was approximately $54 million in the second quarter of 2025, representing a growth of 24% quarter over quarter. A total of 102 commercial patients were treated, representing the highest number of MTAGV infusions for a single quarter of the day. fusion growth was a direct result of increased field activities in existing ATCs and contribution of new ATCs onboarded earlier this year. Our commercial organization is also dedicated to supporting and growing ProLucan sales. Product revenue from ProLucan was approximately $6 million in the second quarter of 2025, an increase of 2% quarter over quarter. Two of the three major U.S. wholesalers restocked during the most recent quarter. As a reminder, First quarter Prolucan sales were attributed primarily to manufacturing and clinical uses, not the main channel tied to MTAGD use. These two channels represent additional revenue growth opportunities for Prolucan. Now that wholesalers are reordering from the main channel, we expect Prolucan revenue to begin to reflect MTAGD demand. Looking forward to the remainder of the year, we are confident in continued growth for MTAGD and Prolucan. We are confirming our full year 2025 total revenue guidance of $250 to $300 million. This aligns with our U.S. MTAGD growth forecast, including expected momentum from community referral activities and large community practices. As a reminder, our 2025 guidance includes sales of MTAGD only in the United States, as well as per week. MTAGD has the opportunity to address more than 30,000 patients globally, to advance melanoma. As Fred stated, we continue to see the potential to achieve Antagni US peak sales of equal to or greater than $1 billion. There is also significant opportunity to add to this potential through international sales of Antagni. Moving on to key launch performance drivers. Our number one goal is to establish Antagni as the preferred option for all appropriate patients. Antagni is a game changer for melanoma patients who have failed first-line treatment. For the first time in advanced melanoma and solid tumors, cell therapy made from the patient's own cells has been shown to induce long-term benefit with curative intent. On last quarter's call, I highlighted three key areas to drive performance and would like to comment on our progress. First, adoption across our ATC network continues with strong, steady growth at early centers. New centers treating patients and increase integration with community practices. A second performance driver is engaging medical oncologists to guide earlier consideration for MTAGD. Our first real-world data shows approximately half of all patients responding, including 60% of patients responding in earlier treatment settings. These results reinforce our messaging in the field and can guide earlier treatment practices within the scope of our label. Our disease education focuses on the benefits of durable responses with one-time cell therapies like mTAGD versus temporary responses and ongoing side effects seen with other treatments. The third area is to penetrate U.S. community oncology networks and increase the frequency, speed, and overall timeliness for mTAGD referrals. Last quarter, I mentioned that we were working to identify alternative distribution channels on top of our traditional specialty distribution. pharmacy that may offer flexibility to support community access for one-time therapies like MTAGD. In direct response to requests from large community practices, we entered our first agreement with McKesson's Biologic Specialty Pharmacy, and other transactions are planned. This new channel will allow hospitals to have the choice to either buy MTAGD directly or go through a specialty pharmacy where they do not have to directly purchase the product. Transitioning to our ex-US strategy, we are making progress toward approval in four additional markets. Canadian approval is expected imminently, and we are making progress toward approval in the UK. We gained priority review for our submission in Australia. We are also in the submission process for Switzerland. In the European Union, as noted in the press release today, we recently withdrew our submission from the European Medicines Agency following lack of alignment during discussions of our clinical data. We are currently evaluating strategic options, such as including a virtual control arm in the submission, to make MTAGD and till therapy broadly accessible to advanced melanoma patients with unmet medical need in Europe. We look forward to providing updates on our regulatory interactions in the near future. As stated previously, our full year 2025 total revenue guidance does not include MTAGD sales outside of the United States. As part of the restructuring, our customer-facing teams remain well-resourced and focused to deliver mTagMe infusions for patients, drive demand, and generate revenue for mTagMe and ProLucan to move Iovance forward. I am committed and motivated to lead our commercial organization toward success. I am deeply committed to Iovance's mission of pioneering a new treatment paradigm for physicians who treat patients with solid tumors, which represent 90% of all cancers. I will now pass the call over to Ivar Balinski, our Chief Operating Officer, to highlight our manufacturing progress. Thank you, Dan.

speaker
Dr. Igor Belinsky
Chief Operating Officer

I will focus today's manufacturing update on commercial performance and recent organizational changes. I'll also build on Fred's introductory comments about our ongoing initiatives to improve cross-margin. Our internal manufacturing facility, the IFM Self Therapy Center, or ICTC, today for both commercial and clinical manufacturing. Our contract manufacturer provides second source through backup. Owning our own facility and relying more and more on internal manufacturing provides us with full control to maintain high quality, implement operational efficiencies, and optimize cost of sales. ICDC also offers us flexibility to scale up rapidly when needed. Manufacturing success for recognizing revenue. Across functional areas of IVAMS, from manufacturing to medical affairs and commercial, we have focused and committed to improving success rates. As a result, the success rates in the second quarter rebounded compared to the first quarter, with lower patient drop-offs and lower out-of-spec rates, and we continue to see an improvement in the third quarter to date. I'd also like to highlight that as planned, we delivered on our goal to shorten manufacturing turnaround time, which is now 33 days from receipt of sales at the manufacturing facility to untag the readiness for return shipment to the ATC. Turning to our strategic restructuring, our manufacturing organization has been realigned for operational excellence. We previously staffed our manufacturing network revenue guidance. Now we have right-sized and optimized the capacity and headcount to align with the revised guidance and growth projections. Our streamlined manufacturing organization and ongoing implementation of operational efficiencies are expected to increase capacity utilization Shifting to the current macroeconomic and geopolitical environment, I will reiterate that iBent is operating at a strategic advantage within the biopharma industry. We continue to expect MTAGV and Prolucon to see minimal impact from tariffs. Regarding our intellectual property, our till cell therapy expertise and manufacturing capabilities are protected by a robust patent estate that is domiciled in the U.S. We own approximately 280 granted or allowed US and international patents and patent rights for mTAGV and other TIL-related technologies expected to provide exclusivity through at least 2042. I'm available to answer questions during the Q&A session, and I will now hand the call to Dr. Friedrich Hinkenstein, our chief medical officer, to discuss our clinical pipeline.

speaker
Dr. Frederick Finkenstein
Chief Medical Officer

Thank you, Igor. Building on my colleagues' comments about MTAG-V or lifelucel, the durability of responses following one-time treatment is a key differentiator from other available and emerging therapies. This durability message was reinforced in the recent publication of the final five-year analysis from our C14401 trial in the Journal of Clinical Oncology and the simultaneous presentation at the American Society of Clinical Oncology annual meeting. unprecedented durability and duration of follow-up were demonstrated in previously treated advanced melanoma patients. 31% of patients responded, with nearly a third of responders ongoing. The five-year overall survival rate was almost 20%. In the real-world treatment settings, we are excited to see even better response rates of approximately 50% overall and 60% in less heavily treated patients. patients following life elusal. We look forward to presenting this real-world data at a future medical meeting. Following the strategic restructuring, our priorities are to expand mTagV into additional solid tumor types and earlier lines of therapy, and to advance our key next-generation TIL and TIL treatment regimen. In frontline advanced melanoma, Till then, 301 is our global registrational phase 3 trial designed with FDA and EMA input to show the contribution of components. We are investigating mTAGV in combination with pembrolizumab compared to pembrolizumab alone. Till then, 301 remains on track as the confirmatory trial for mTAGV monotherapy in our initial indications. And this trial could also support accelerated and full approval of MTAGV in combination with pembrolizumab in frontline advanced melanoma. We look forward to sharing results from several clinical trials before the end of the year for lifeluzole in non-small cell lung and endometrial cancers, as well as on our PD-1 inactivated tilt cell therapy, IOV-4001. IOV-LUN202. as our registrational program intended to extend the label for life-elusive monotherapy to include previously treated advanced non-small cell lung cancer. This trial design aligns with FDA guidance for single-arm trials to support accelerated approvals for single agents in conditions with unmet medical needs. Chemotherapy, the current standard of care in this treatment setting, provides limited rate and duration of responses. The FDA previously provided positive regulatory feedback on the IOV-LUN2-2 clinical trial design and the proposed potency assay matrix to support registration. We expect data from IOV-LUN2-2 to support a potential regulatory decision on U.S. accelerated approval in 2027 for previously treated non-small cell line cancer patients. In our IOV-END-201 clinical trial, we've seen promising signs of initial efficacy for Liferutal monotherapy in previously treated patients with advanced endometrial cancer. Our PD-1 inactivated TIL cell therapy, IOV-4001, is in a first-in-human trial and reflects our leadership in next-generation approaches to optimize TIL and TIL treatment regimens. We are also treating patients in a Phase 1-2 clinical trial of IOV3001, a next-generation IL-2 for use with the TIL cell therapy treatment regimen. Finally, we plan to submit an investigational new drug application to FDA early next year for IOV5001. This genetically engineered, inducible, and tethered IL-12 TIL cell therapy may expand our development opportunities into a wide range of common solid tumor cancers. I'm happy to address questions during the Q&A session. Now turn the call over to the operator to begin the question and answer session.

As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. In the interest of time, we ask that you please remember yourself to one question. You may rejoin the queue for any additional questions or follow-ups. Please stand by while we compile the Q&A roster. Our first question comes from Yonan Zhu with Wells Fargo. Your line is open.

speaker
Yonan Zhu
Analyst, Wells Fargo Securities

Oh, great. Thanks for taking our questions and congrats on the quarter. I was wondering, can you talk about the patient number, you know, from 1Q to 2Q? Because I don't think we had a good sense of exactly how many patients you infused last quarter in 1Q. We wanted to understand the growth in patient number. And I also think you might have increased the price. So perhaps talk about the price change and impact for MTABV revenue as well. And if you can also comment on where do you think those infusion numbers will go in the coming quarters relative to your guidance and confidence, that would be super helpful. Thank you.

speaker
Dr. Fred Vose
Interim Chief Executive Officer and President

Thank you, and I'll start, and then I'll ask Dan Kirby to add some comments to this, too. So the number of infusions we had this quarter was 102. Last quarter it was 83. So that was substantial growth over the last quarter, obviously. There was a price increase that came into effect on April 1st, which took the price of the product of Ampagni to $562,000. We expect growth, and I'll let Dan talk about what we expect in the second half of this year.

speaker
Dan Kirby
Chief Commercial Officer

Go ahead, Dan. So for the price increase, I think your question was, did we see any impact of the price increase on demand? We did not see any impact. In fact, demand increased after the price. So we didn't factor that in as being any kind of headwinds to follow. So with that, we also look at the future and where we see patients coming in. We have our new centers coming on, as we talked about in previous quarters, and they continue to ramp up demand, as well as our existing centers. What we do see in the future happening is we're in the process of opening some ATCs that are closer in the community networks. I mentioned the distribution channel we added. That is specifically at their request, which gives us access to hospitals that normally we're not going to purchase and pack. So we do see demand in the second half. continuing to be strong to meet the guidance that we provided.

speaker
Yonan Zhu
Analyst, Wells Fargo Securities

Sorry, if I may quickly follow up. I think I heard the growth in page number was from 83 to 102. Sorry, 85 to 102.

speaker
Dr. Fred Vose
Interim Chief Executive Officer and President

Yeah.

speaker
Yonan Zhu
Analyst, Wells Fargo Securities

85 to 102. That's pretty good growth. Do you anticipate similar growth going forward or any color there, just so we have a better sense about what to expect in the coming quarters? Thank you.

speaker
Dan Kirby
Chief Commercial Officer

We anticipate demand to continue to be strong. As far as quarter-on-quarter growth, we don't want to guide to that. We want to still stick to the 250 to 300 range that we have in our guidance with it, which would indicate second-half demand will be strong.

speaker
Yonan Zhu
Analyst, Wells Fargo Securities

Great. Thanks.

speaker
Operator
Conference Operator

Thank you. Our next question comes from Peter Lawson with Barclays. Your line is open.

speaker
Peter Lawson
Analyst, Barclays

Great. Thank you so much. Thanks for the detail on the call. Just as you think about the guidance, just your level of confidence around proleukin, you mentioned it kind of accelerating in the second half, kind of what gives you that level of confidence, and what do you think the proleukin number could be? And have there been any changes in the number of proleukin injections? Thank you.

speaker
Dan Kirby
Chief Commercial Officer

Hi, Peter. I'll take that question. I think for proleukin in the mainline channel, what we did see as evidence in the revenue from Q1 was we're seeing the manufacturing and the clinical trial channel that represented the Q1 revenue. In Q2, we started seeing the reordering at regular basis from two of the top three wholesalers in the U.S., So what we expect to see moving forward is those orders continuing in from the two, and then the third one coming on later this year. So it'll start to reflect more of the MTAGV utilization. Along with that, we are seeing strong demand to use with MTAGV, so we have not seen the number of doses. Again, it's zero to six doses with one dose of MTAGV. We're not seeing the doses of Prolucan change by center. Each one will do it differently, but the average doses remain consistent. and then finally we do anticipate those other two channels we've been talking about that we've booked revenue and q1 on continuing to order throughout the year so you're you'll see some pickup in in prog lucan based on the fact that the wholesalers are coming online gotcha thank you so much thank you our next question comes from andrew sai with jeffrey's your line is open hey good afternoon thanks for the updates um appreciate you taking the question so

speaker
Andrew Sai
Analyst, Jefferies

If the guidance for net cash burned is going to be less than 235 over the next year, and I believe restructuring happens later in the year, it feels as if you're expecting gross margins to improve meaningfully, maybe even as early as Q3 relative to Q2 and Q1. Is that accurate? And if so, can you give us some color why that could be the case in terms of a meaningful margin improvement? Thank you.

speaker
Dr. Fred Vose
Interim Chief Executive Officer and President

Yeah, Andrew, thank you for the question. It was 245, not 235. You can see it in the press release and in our remarks there. But your question is still a good question. Yes, we expect margins to improve. That's the whole name of the game right now. We're pushing very hard. And a lot of the restructuring activities are really focused on improving margin. Now we're going to enter a phase of operational excellence over the next couple quarters to really tighten down on cost of sales and do a lot of work to improve margins even more. And as volume ramps up, we'll also see improvements in margins because cost of sales will stay low while revenue goes up, especially as we scale up and use our ICPC facility. So you're absolutely right. We expect to see margin growth. And again, this quarter we saw a good margin. If you back out the non-cash items and things like that, you see a very good margin on a cash basis that we have already now. As you see more prognosis sales increase and as you see us do all those things, I think you'll see margins go up significantly.

speaker

Thank you. Thank you. Our next question comes from Salim Syed with Mizuho. Your line is open.

speaker
Bennett
Analyst, Mizuho Securities

Hi, this is Bennett for Salim. Thanks for taking our questions. Could you elaborate on the decision to withdraw the marketing authorization application in Europe? What was the feedback with AIMA and what are the steps that you're planning to take to commercialize in Europe? And regarding the announcer structuring, are you also planning to reduce R&D expenses And if so, could you comment on any specific actions you would be planning to take to reduce, for example, clinical expenses? Thank you.

speaker
Dr. Fred Vose
Interim Chief Executive Officer and President

Yeah, I'll take the second question first. We did reduce some R&D expenses, but we are not expecting any significant changes in our clinical pipeline as we discussed on the call. With respect to the EMA, we withdrew when we learned late in the review process that we need to include additional analysis in our submission. So what we want to do is go back and resubmit with an additional analysis such as the virtual control arm. Our strategy does not require us to run additional clinical trials, and we think that can happen relatively quickly. We'll be seeking scientific advice from the EMA soon to try and get back in there and work on that again with them. But that was really what the issue was. It has to do with the data package that was submitted, which we submitted was similar to the FDA package and Health Canada package and everything else, and they would like to see some more. And the easiest route for us to do that is to withdraw and resubmit.

speaker
Nick
Analyst, TD Cowen

Great. Thanks. This is Nick on for Tyler. Thanks for taking our question. Can you provide an update on how infusions are tracking for MTAG-B quarter to date? And then second, in the first earnings call, in the first quarter earnings call, you noted that 69% of ADCs have infused one patient, while 16% infused 10 or more. Can you provide an update on these metrics and the plan to increase prescribing?

speaker
Dan Kirby
Chief Commercial Officer

Thanks. I'll take that one. Thanks for the question. For the infusions quarter to date, we do see strong demands. However, we can't comment on how many infusions quarter to date. That's been our policy. As far as the percentage increase with those percents, They have gone off, obviously. We have not appreciably a lot more centers that came on in the last quarter. However, we're going to have 24% infusion. So those numbers by centers are going up with it, but we decided not to continually track those as a metric.

Hi, good afternoon. Thanks for taking our questions. So this EMA feedback on melanoma, do you expect this to impact your path forward in PD-1 treated non-small cell lung cancer?

speaker
Dr. Fred Vose

No, not right now. Absolutely not. It has nothing to do with the United States whatsoever. Raj, Raj, for your key comment on this.

speaker
Dan Kirby
Chief Commercial Officer

Yeah, I don't think, Colleen, that any impact on the going forward or continuing of non-small cell lung cancer.

speaker
Colleen Cousy
Analyst, Bayard

Great. And one quick follow-up. What sort of issues does moving to a specialty pharmacy solve for centers versus just buying through you directly?

speaker
Dan Kirby
Chief Commercial Officer

It's a great question. It really solves, if you think about the hospitals that are involved with the community clinics and you get close to where the patients are, a lot of times you're dealing with medium-sized hospitals that have all the capabilities to administer and tag me. However, one-time therapies that have higher price tags, the finance department does not want to bring those in. So they would rather go around where they would go through a specialty pharmacy where the purchase would happen through the specialty pharmacy. and especially farmers who get reimbursed from the payer versus the purchase happening directly from the finance department at the hospital.

speaker
Renny Benjamin
Analyst, Citizens

Hey, guys. Thanks for taking the questions. Maybe one, can you just talk a little bit about the numbers in terms of patient drop-offs versus the manufacturing kind of out-of-spec rates? I think Igor had some prepared remarks regarding that. Can you just talk about the specifics from first quarter to second quarter and how you see that potentially improving throughout the rest of the year? And then kind of just going back to a previous question regarding McKesson, How do you see this, you know, potentially improving revenues going forward? Like, is this something that should kind of minimally increase revenues? How should we be thinking about the number of patients these one-off hospitals, you know, how much they might use this?

speaker
Dr. Igor Belinsky
Chief Operating Officer

Adrian, thanks for the question. So, on the first part of the question, as I mentioned, The manufacturing success rates normalized in the second quarter compared to the increase in the first quarter, so both the out-of-spec rate and the patient drop-off rates decreased, and we're seeing further improvement in the third quarter so far, and as you can see in the queue, You will see in the queue the scrub costs went down in the second quarter compared to the first quarter, if you want to quantify that. Beyond that, we're not sharing the exact percentages, but again, you can look at the scrub costs and see the decrease in both absolute terms and the relative percentage.

speaker
Dan Kirby
Chief Commercial Officer

And I'll answer the question regarding both patient drop-off as well as the impact of specialty pharmacy, which are a little bit related. So patient drop-off does remain somewhat consistent, although we did see that we were getting patients a bit earlier in this quarter versus previous quarters, and we weren't seeing as many patients that were not making it even to tissue procurement. So we are making strides in that avenue. The impact of specialty pharmacy allows us to actually get closer to those patients so we can get healthier patients upstream. And how we should be thinking about that is we're starting our journey right now. Other cell therapies are following our lead. Gene therapies and other therapies that are higher priced have already gone down this road successfully. So as we think about how this can have an impact on it, this could get us next to those clinics that are affiliated with those hospitals inside of the network that they can treat patients inside of their network without the cost burden. So it could have a big impact long-term. We already have several accounts right now that have requested it that we're opening up this channel for. So we will have some impact later this year.

speaker
Renny Benjamin
Analyst, Citizens

Got it. And if I can just have a quick follow-up just regarding the clinical trials that are ongoing for Friedrich. Can you provide us any color in terms of you know, how many patients are enrolled in each of these studies? How many patients' worth of data might we see for non-small cell as well as the other ones that we're expecting like endometrial in the second half of this year?

speaker
Dr. Frederick Finkenstein
Chief Medical Officer

Yeah, happy to respond to that. So I think what we said is that we're going to share data by the end of the year. We will provide that information as part of those updates. I don't think that we will pre-define at which patient number we would be doing that. Okay, thank you.

speaker
Operator
Conference Operator

Thank you. Our next question comes from David Dye with EBS. Your line is open.

speaker
David Dye
Analyst, EBS

Hey, guys. Yeah, thanks for taking my questions. So, first question just around thinking about the patient ramps more intactly. Based on the current round rate, we calculated that patients need to grow about 26 to 32 patients per quarter over the next couple quarters, and it hits midpoint of the guidance, which is providing a detail that you're on track to hit that patient growth. And secondly, on the ATCs, you have 80 right now. How many of these ATCs are newly activated compared to last quarter, and how many are still being activated?

Chief Commercial Officer

So one of the things, I'll take that question with it. As far as the patient ramp, just to let you know, the $250 to $300 million is combined revenue between Prolook and NMTAGP. So on the map there, those numbers are 26 to 30 per quarter. But we are confident that we are tracking towards that range and seeing MTAGD demand continue to strengthen and grow towards the end of the year, as well as Prolucan, as we mentioned before, having all three wholesalers starting to order very soon, two of those doing so currently in the main channel, give us our path forward to hit within that guide. The second question regarding how many new ATCs, again, we're focusing on quality, not quantity. We happened to open several ATCs in the last quarter with it. Each one of those has been carefully vetted to have referral patterns in place so they can get earlier patients in there. And we are seeing, and I'm not going to give the exact numbers here, we are seeing a substantial number of patients coming in the queue, both that have been already infused by them, but also to where they're enrolling in there to have manufacturing done for a tagging for their patients.
