Christian Itin -- Chairman and Chief Executive Officer
Thank you, Lucinda, and good morning to all of you, and thank you for joining us. I'm pleased to review our progress for the full year of 2019, as well as some recent company highlights in the fourth quarter. Let me first begin by giving an overview of our corporate strategy on Slide 5. We're focused on progressing our potential best-in-class therapies, AUTO1, for adult ALL and AUTO3 for DLBCL, with major value steps expected through 2020 and 2021.
We're in the process of starting our first pivotal study with AUTO1 in adult ALL, which we'll both drive to completion in 2021 and target approval in 2022. We will also move our DLBCL program, AUTO3, to proof of concept by midyear and assuming a go decision at that time, would expect to be preparing for a pivotal study in this indication. In addition to our two new lead clinical candidates, we will be delivering clinical milestones related to our T-cell lymphoma program, AUTO4, and also our first solid tumor indication. To date, we have seen encouraging initial antitumor activity with AUTO6 targeting GD2, and we are now progressing an enhanced next-generation modular candidate, AUTO6NG, into the clinic in the second half of this year.
AUTO6NG is specifically tailored to address some of the challenges related to the solid tumor microenvironment as initially presented at SITC last November. Additionally, we also see two of our next-generation development candidates enter Phase 1 this year. It is AUTO1NG in pediatric ALL and AUTO8 in multiple myeloma. Finally, I would like to highlight our longer-term value-creation steps related to our broad and highly innovative next-generation preclinical pipeline.
In addition, we've been working extensively to solidify our scalable, fully enclosed manufacturing platform capabilities, which have, to date, delivered products to our AUTO1 and AUTO3 clinical programs. Turning to Slide 6, which gives an overview of our company highlights for fiscal-year 2019, as I mentioned, we have made great clinical progress with our lead programs, AUTO1 in adult ALL and AUTO3 in DLBCL. In terms of our program in adult ALL, we've presented updated results for ALLCAR19, the Phase 1 trial evaluating AUTO1 in adult patients with recurrent refractory ALL in an oral presentation at ASH. The trial enrolled patients with high tumor burden, who are considered high risk for experiencing the kind of toxicities normally associated with CAR T therapy.
As of the data cutoff of November 25, 16 patients had received at least 1 dose of AUTO1. AUTO1 was well tolerated, with no patient experiencing grade three or higher cytokine release syndrome, and three of 16 patients or 19% who had experienced neurotoxicity and particularly, patients with high levels of leukemia in the bone marrow. All of those neurotoxicities restrict the result for steroids. Of 15 patients available for efficacy, 13 achieved molecular remission at one month, and all patients have ongoing CAR T cell persistence at the last follow-up.
As touched on above, in the patients dosed with AUTO1 manufactured in a closed process, nine out of nine patients achieved a molecular CR at one month and six months event-free survival. Overall survival in this cohort was 100%. More recently, at the EHA-EBMT CAR T Meeting end of January, our chief scientific officer, Dr. Martin Pule, presented very encouraging updated data for AUTO3 to treat adults with relapsed/refractory diffuse large B-cell lymphoma, which we'll expand on later part of the presentation.
At SITC in November, we presented exciting preclinical data in our AUTO6NG program, which we'll talk to a little later. Finally, through the course of 2019 and early 2020, we completed two successful fundraisings, raising in aggregate approximately $184 million in net proceeds. In terms of our manufacturing capabilities, the Catapult site is now fully operational and delivering clinical products for patients in Europe and the U.S. We also continue to progress the buildout of our U.S.
facility, which has expected capacity for 5,000 patients per year. Moving to Slide No. 7. Let's start the discussion with some more detail of our most advanced program, AUTO1 in adult ALL.
We do believe there is a significant opportunity and unmet medical need in the relapsed and refractory B-cell acute lymphoblastic leukemia setting, which represents an underappreciated and significant commercial opportunity in terms of both the potential market size, as well as the high level of unmet need in the management of the disease. Worldwide, approximately 8,400 patients are diagnosed every year, with about 6,000 of those patients coming from the U.S. and the top five European countries. While response to initial combination chemotherapy regimen is encouraging, only 30% to 40% of adult ALL patients will achieve long-term remissions, and the median survival for adult patients with relapsed/refractory ALL is less than one year.
While Kymriah, a CD19 target in CAR T therapy, was approved for pediatric ALL patients in 2017, no CAR T therapy has been approved for adult ALL patients. The only redirected T-cell therapy approved for adult ALL is blinatumomab or BLINCYTO, a bispecific CD19-targeting T-cell engager. Blinatumomab has a 42% response rate, yet the durability of the response is limited, and it's event-free survival is only 31% at six months. CAR T therapies are clearly highly active in this setting, but we currently see no clear sense of durability without subsequent allograft.
And it is worth noting that patients are generally more fragile with more comorbidities in this setting. Initial CAR T therapies, which have been notable with high incidences of severe CRS and cases of fatal neurotoxicity, show less-than-suitable profiles for addressing this pool of very sick patients. We will have further updates from our ongoing Phase I ALLCAR19 study through the course of 2020 and starting at EHA, where we'll have approximately 6 months additional follow-up on the patients presented at ASH at the end of last year, and we also will include additional patients. Turning to Slide No.
8, I wanted to spend some time focusing now on how we have specifically designed AUTO1 for a durable response without the need for allotransplant and achieving a reduced level of severe cytokine release syndrome. We wanted to achieve a product that can put pressure on the tumor for long periods of time, and at the same time observe at the gate a good safety profile. We've touched on this earlier, but this is particularly important as elderly patients tend to be a lot more fragile at more comorbidities and are much less likely to tolerate toxicity. The durable benefit in adult ALL patients requires an ability to put long-term pressure on leukemia.
So when we look at the current generation of CAR T therapies in the field, they all share the same construction features and, particularly, an identical binder called FMC63 to recognize the CD19 antigen of the leukemia cells. It is the binder that has an ability to hold on very tightly to CD19 and has a very high affinity. As a consequence, this creates a very unphysiological engagement with the target cell. The result being overly activated CAR T cells, which drive cytokine release, differentiation, and exhaustion, all features that drive toxicity and lower persistence.
We have positized that for AUTO1, that if we were able to generate a product that could deliver the kill but then disengage rapidly, we should be able to avoid overactivation of the CAR T cell and the subsequent high levels of cytokine release and thus, generate a program that has an improved toxicity profile and overall, a better efficacy profile as well. We also believe that the product should be in better shape, less differentiated, less exhausted, which should drive better persistence and, as such, should also be present over a longer period of time in the patient, exerting pressure on leukemia. Turning to Slide No. 9, in this table, we compare the current standard of care, blinatumomab or BLINCYTO, to the AUTO program.
Remember, most of the patients that we've treated have already received blinatumomab or inotuzumab and failed on those therapies. As you can see, the CR rate for blinatumomab is 42%. All patients in AUTO1 are at 87%. The event-free survival at six months for blinatumomab is 31%.
We've reported 68% for the total population, as well as an improved number for the patients treated with the Clovis manufacturing process. This suggests a product profile that is emerging to be clearly differentiated from BLINCYTO, most notably from other emerging CD19 CAR T approaches. If these findings are confirmed in our registration trial, AUTO1 has the potential to set a new standard of care in adult ALL. On Slide 10, I'd like to summarize where we are with AUTO1 now in adult ALL.
This program will be the first Autolus program to move to a pivotal stage. We have filed a clinical trial authorization of CTA in the U.K. at the end of last year, and the IND is expected to be filed in the U.S. this month.
The trial will be a single-arm study of approximately 100 patients and morphologically relapsed among sites in the U.S. and Europe. The primary endpoint will be the overall complete response rate. Secondary endpoints will include MRD-negative complete response and event-free survival.
We're targeting the second half of 2021 for a BLA filing. Moving to Slide 11, our program in diffuse large B-cell lymphoma. We believe that DLBCL is a large commercial opportunity and given the market size and aggressive nature of this disease. DLBCL is the most common type of non-Hodgkin lymphoma, with approximately 24,000 patients diagnosed every year in the U.S.
alone. High-dose chemotherapy, combined with a monoclonal antibody, led to remission in about 50% to 60% of the patients. Thus, we expect that the addressable population to be approximately 10,000 patients in the U.S. and EU5 combined.
DLBCL represents an aggressive and rapidly progressing cancer for patients who relapse or are refractory to first-line therapy. The current standard of care for second-line therapy consists of a platinum-based chemotherapy regimen with rituximab. Patients who respond to second-line therapy may go on to receive autologous hematopoietic stem cell transplant or HSCT. Patients who are not candidates for HSCT or those who do not respond to second-line therapy or who relapsed after HSCT are typically treated with the third-line salvage chemotherapy.
These patients have a poor prognosis and treatment is generally palliative to try to prevent further cancer growth without the intent to cure. There are two approved CAR-T products available today. Yet here, there remains a high unmet need. Despite highly active CD19 CAR T therapies in the relapsed/refractory setting, most of the responses are not durable in toxicity limits, broad application, particularly in the outpatient setting.
Turning to Slide No. 12, we highlight the current status of CAR T cell therapies in DLBCL. Despite an objective response rate of 70% to 80% and high base CR rates of 40% to 55%, only 29% to 37% of the patients achieved a durable complete remission in DLBCL. Approximately one-third of the CRs are lost over time.
And loss of CRs are caused by PD-L1 upregulation, which contributes to CAR T exhaustion and CD19 antigen loss. Safety is also an issue with high rates of severe cytokine release syndrome of 13% to 22% and severe neurotoxicity of 12% to 28%. The early onset and severity of toxicities require intensive inpatient management. Moving to Slide 13, we profiled the desired features of CAR T necessary to target a broad use across all settings of care, including outpatient therapy.
Key features include a high sustained complete response rate, preventing target negative relapse on checkpoint-mediated resistance, as well as low severe CRS without intensive management and low neurotoxicity rates. The latter safety profile elements, lending themselves to use that would not require intensive management of these patients and ultimately, may allow you to actually treat these patients in an outpatient setting and avoid readmissions of those patients back at the hospital. Continuing to Slide 14, you can see that we have designed a product in AUTO3 that targets a total addressable relapsed/refractory DLBCL patient pool far exceeding those that can be reached by the approved products. Patients received the approved products, for the most part, is in-patients in centers of excellence because of the high rate and severity of toxicities.
And as such, the market opportunity is limited to approximately 20% of the patients that were treated in these centers, an even smaller groupings of patients that are relatable for approved CAR T products. However, with minimal tox management of AUTO3, this would allow treatment across all settings of care, increasing healthcare utilization of our product candidate and growing the addressable market and maximizing reimbursement options compared to approved products. If we now move to Slide 15, we highlight the preliminary efficacy we presented at EHA. As of the data cutoff of January 21, 2020, in the cohorts dosed at 450 million cells of AUTO3, plus pembrolizumab, five out of seven patients achieved response and four out of seven patients achieved a complete response.
Turning to Slide 16, we show that across all those levels, seven out of eight complete responders had ongoing complete responses at a median follow-up of up to six months, range of one month to 18 months. All seven out of seven complete responders treated with AUTO3 and pembrolizumab have ongoing complete responses as of January 21, 2020, at a median follow-up of three months, a range of one to 18 months. Looking at Slide 17, AUTO3 continues to demonstrate a safety profile, much like the desired profile we described earlier, which may allow use in the larger outpatient setting. No patients experienced grade three or higher cytokine release syndrome were reported with primary treatment.
And as of the data cutoff, no patient has experienced neurotoxicity of any grade in cohorts treated with AUTO3 and pembrolizumab. You will see this compares very favorably to other CAR T therapies, both approved and in development across the competitive landscape. Overall, as summarized in Slide 18, we are very pleased with the profile of AUTO3 to date, its successfully manufactured product for all patients from the cell and gene therapy Catapult at Stevenage, and the AUTO3 program is on track for a decision middle of this year to advance the program to Phase 2. On Slide 19 onwards, I would like to conclude with a brief discussion of three AUTO programs in our pipeline, because they have the potential to bring additional value inflection in 2020 and beyond.
Slide 19, we highlight our unique targeting approach in T-cell lymphoma. We've been able to decide for very small differences in the amino acid sequence of the T-cell receptor value chain constant domain, such that we identified two mutually exclusive receptors, which can be individual targeted by antibodies unique to the specific subtype. Unlike B-cell approaches, an individual cannot live without the T cells, and therefore, this approach allows us to salvage the subtype of T cells likely to represent an equal proportion in the body in order to restore a functional immune system. Moving to Slide 20, we recently revealed the clinical outcome of patient one, which despite having been treated at the lowest dose of 25 million CAR T cells, showed a complete metabolic response.
The patient subsequently had progression on day 71. Patient enrollment in our Phase 1 study with the more advanced product, AUTO4 targeting TRBC1, is ongoing with supply from the Catapult. As a result, we expect to present initial Phase 1 data by the end of 2020. We remain very excited about this program and the opportunity to progress another specifically tailored product utilizing our advanced modular approach to a disease setting where no other CAR T product option exists.
Finally, on Slide 21 through 23, we summarize some important points from our lead program in solid tumors. Focusing on Slide 21, solid tumors have remained a challenging area for the advancement of cellular therapies due to the complexity of the microenvironment and the ability to target disease-specific antigen. AUTO6, a GD2-targeted therapy has been encouraging, has shown encouraging preliminary data, demonstrating the initial antitumor activity, giving us confidence that this target is an interesting and relevant target to pursue. Turning to Slide 22, we draw your attention to our modular approach to enhance AUTO6NG for the solid tumor microenvironment.
We have empowered our next-generation product to tackle the key areas that have previously been shown to hamper responses in the solid tumor environment. AUTO6NG leverages the same GD2-targeting CAR T, but increase persistence and also improve the persistence, as well as help the cells survive in a checkpoint-rich and TGFBeta-rich environment. This product has been specifically designed to address the persistence, control tumor defenses. Turning to Slide 23, at SITC, we were excited to reveal data showing that the addition of these modules to the AUTO6NG product was shown to augment its functions by extending T-cell persistence and rendering modified T-cells resistant to both TGFBeta and PD-1, PD-L1-driven immune inhibition in vitro.
We've also revealed that the clinical outcome of patient 1 in our Phase I program, despite being treated at the lowest dose, demonstrated encouraging endpoints of activity. We believe AUTO6NG is positioned for additional value inflection as we commence the Phase 1 study second half of 2020. With that, I will turn over the call to Andrew for our third-quarter 2019 financial update. Andrew?
Andrew Oakley -- Chief Financial Officer
Thanks, Christian, and good morning or good afternoon to everyone. It's my pleasure to review our financial results for the full year, January through December of 2019, and we are on Slide 25. Net total operating expenses for the 12-month period ended December 31, 2019, were $146 million, and that was net of grant income of $2.9 million. That compares to net operating expenses of $74.1 million, also net of grant income of $1.5 million for the same period.
The increase in total net operating expenses was due in general to the increase in development activity to support the advancement of our product candidates, increased headcount primarily in our development and manufacturing functions, as well as the cost of being a public company. Research and development expenses increased to $105.4 million for the year ending December 31, 2019, from $48.3 million for the year ended December 31, 2018. Cash costs, which exclude depreciation, as well as share-based compensation, increased to $83.4 million from $41.5 million. The increase in research and development costs of $41.9 million consisted primarily of an increase in compensation-related costs of $20 million, primarily due to an increase in headcount to support the advancement of our product candidates in clinical development and investment in manufacturing facilities and equipment; an increase of $4.1 million in research and manufacturing consumables, in part due to the migration and expansion of our research and process development laboratories from Forest House to our new location in the MediaWorks facility; preparations in advance of any potential disruption to supply arrangements that may occur due to Brexit; as well as validation and training costs as part of the start-up at the Catapult facility; an increase of $10.2 million in facility costs, primarily related to increase the number of facilities, mainly at MediaWorks and at Catapult; an increase of $3.8 million in project expenses related to activities to prepare, activate and monitor clinical trial programs; and an increase in legal and professional fees that includes a decrease in milestone payments of $0.5 million consisting of a milestone payment to UCL Business plc of $2 million in 2018; and a milestone payable to Noile-Immune Biotech in the current year; as well as an increase in IT and general office expenses as well to round it out.
General and administrative expenses increased to $39.5 million for the year ended December 31, 2019, from $27.3 million for the year ended 31 December 2018. Cash costs in this area, which exclude depreciation, as well as share-based compensation, increased to $26.6 million from $21.4 million. The increase of $5.2 million consisted primarily of an increase in compensation-related costs of $2.6 million due to an overall increase in headcount; an increase of $1.9 million in commercial activities; and an increase in public company compliance costs of around $1 million; an increase of $0.7 million in facility costs, and this was offset by a decrease of $1 million in IT charges and other office expenses. Net loss attributable to ordinary shareholders was $123.8 million for the 12-month period, compared to $57.9 million for the same time frame in 2018.
The basic and diluted net loss per ordinary share for the 12 months ended 31 December 2019, totaled $2.88, compared to a basic and diluted net loss per ordinary share of $1.48 for the 12 months ending 31 December 2018. Cash and cash equivalents at the end of the period totaled $210.6 million, and that compares with $217.5 million at the end of December 2018. Adjusting for the recent follow-on offering in January, where we raised gross proceeds of $8 million, our cash at the end of January approximately stood at around $286 million. And we anticipate that that cash on hand provides us with the runway into 2022.
With that, I will now hand the call back to Christian to give you a brief outlook on expected milestones. Christian?
Christian Itin -- Chairman and Chief Executive Officer
Thanks, Andrew. Let me conclude this part of the management discussion with a review of the upcoming milestones and news flow through 2020. Let's move to Slide 27. The upcoming nine months will be an eventful period for us with multiple clinical milestones and opportunities for value creation.
Our chief operational focus will be commencing the registration trial for AUTO1 in adult ALL in the U.K. and U.S. We also expect to report data across multiple programs and to progress a number of our other clinical trial candidates, specifically updates on our ongoing clinical trials, initiation of Phase 1 study of AUTO1NG in pediatric ALL in the first half of this year; a go-no-go decision on Phase 2 initiation of AUTO3 in DLBCL middle of this year; initiation of a Phase 1 study for AUTO6NG toward neuroblastoma toward the end of this year; and initiation of the Phase 1 study of the next-generation program in multi myeloma called AUTO8 also toward the end of 2020; as well as working on some exploratory clinical trials toward allogeneic approaches as well. In conclusion, on Slide 28, I'd like to recap the major messages from today's call.
First, AUTO1 is our foundational program and the first Autolus program expected to move into a pivotal stage. Given the positive safety and efficacy profile today, we believe that AUTO1 has the potential to be a best-in-class CD19 CAR T in ALL. Secondly, our next priority is on AUTO3 in DLBCL, which, obviously, is expected and slated for clinical data middle of the year. We expect to report full Phase 1 data for AUTO3 in the middle of 2020 to reach a decision point for a Phase 2 trial initiation thereafter.
Looking ahead to the remainder of the year, we see opportunity for additional value steps for T-cell lymphoma, as well as the start for the AUTO6 next-generation program, targeting GD2-positive tumors. The company has a strong balance sheet with $286 million in cash, which will create a run rate into 2022. And finally, we're looking forward to seeing many of you at the upcoming AACR, ASCO and EHA meeting over the upcoming few months and are now happy to take questions. Operator, please open the line.
Thank you.
Operator
[Operator instructions] Our first question comes from Debjit Chattopadhyay with H.C. Wainwright.
Unknown speaker
Thanks for taking the question. So I have a question on the barriers -- oh, this is Aaron for Debjit, by the way. I have a question on the barriers to outpatient treatment with AUTO CAR-Ts in DLBCL. So we were looking at a study in which they treated patients with a median of only two prior lines with liso-cel in an outpatient setting, and they ended up hospitalizing 59% of the patients at the first time of CRS or neurotox.
So what do you think would be a reasonable level of hospitalization that could warrant expansion to the outpatient setting? And do you think that there could be more competition in certain subsets of patients in the outpatient setting for various auto CAR-Ts?
Christian Itin -- Chairman and Chief Executive Officer
So a very good question, Aaron. And it's obviously a very interesting kind of analysis when you look at the field, where you realized that approximately at this point, only about 20% of the patients sort of can be targeted with CAR T therapy in the current setting, which is really focused on the centers of excellence. And the reason for that is predominantly driven by the requirement for fairly intense management of these patients to deal with the adverse event profile that the current products have. And what we basically quoted that basically flux of patients back into the hospital that was considered initially to be treated in outpatient setting just indicates the need for a significant level of management of these patients, to begin with.
And that's a fundamental property of the product itself. And I think it's shared by all of the current products that have either been approved or are about to be approved. So what I think we were highlighting in our presentation is that the AUTO3 at this point has shown no high-grade cytokine release syndrome. And this did not require actual management of the patients.
So we didn't actually have to put steroid covering that we have been -- didn't have to put tocilizumab in these patients as a preventative measure and management measure. This is the data actually from unmanaged patients. What was probably more surprising and obviously a remarkable outcome is the fact that we have seen no neurotoxicity of any grade in the patients that we have treated in combo, in combination with pembro across a set of dose levels. And that is truly surprising because none of the programs redirecting T cells, targeting CD19 to date has shown this type of a feature.
All of them actually have neurotoxicity as a core type of adverse event that they do experience. The fact that we have seen none, without managing the patients, gives us a lot of confidence that we have a type of profile that should be well manageable also in an outpatient setting and also, importantly, in centers that are not the few centers of excellence in the country, but also much more broadly in the periphery, where, in fact, most of the DLBCL patients do get treated in the U.S. And I think that's going to be a core feature for the program. And to date, what we've seen as a profile certainly has not been reported by anyone else within the field.
Unknown speaker
Great.
Christian Itin -- Chairman and Chief Executive Officer
Thank you, Aaron.
Operator
Our next question comes from Chad Messer with Needham & Company.
Chad Messer -- Needham and Company -- Analyst
Great. Good day. Thanks for taking my questions. Maybe we'll just start by continuing a little bit the discussion we're just having on AUTO3 and safety, about a go/no decision coming up.
Is there an actual bar where you can describe? I mean, 0% would be awesome, but maybe not all that practical to hold on to.
Christian Itin -- Chairman and Chief Executive Officer
I think if you have a low level of neurotox, low-grade neurotox at a low level, I think that would be very well manageable. We also should remember that the patients treated with BLINCYTO actually are treated in an outpatient setting, and they've managed that way. And the neurotox rate obviously for BLINCYTO is not zero, but it is less intense than what we see with the CAR-Ts that are currently gone through approval or close to approval. And so there's clearly a bar here that is not a zero number, but definitely want to see a low level of neurotoxicity.
And you want to avoid the high-grade cytokine release syndrome, which really requires you to go back into the hospital.
Chad Messer -- Needham and Company -- Analyst
OK. And then just again, thinking on efficacy and safety bars. On the AUTO4 program, I mean, for T-cell lymphomas, we don't have a good standard of care to compare ourselves up against. So what do we need to see later this year for AUTO4 in order to get excited and optimistic about that one?
Christian Itin -- Chairman and Chief Executive Officer
I think what we would like to see is we see a good level of responses in those patients and evidence that we start to see also a reasonable level of persistence. So we get some durability of those responses. As you pointed out, this is a very devastating disease. There are very little options at this point.
And I think a program that gives you a reasonable level of remissions in these patients together with some durability of response will go a long way. And clearly, the bar for this indication is lower than what we're seeing in lymphoma and certainly much lower than what we're seeing in leukemia.
Chad Messer -- Needham and Company -- Analyst
All right. Great. Well, thanks. We're looking forward to all the data you guys are coming up this year.
Christian Itin -- Chairman and Chief Executive Officer
Excellent. Thanks for joining, Chad.
Operator
Our next question comes from Biren Amin with Jefferies.
Biren Amin -- Jefferies -- Analyst
Hi, guys. Thanks for taking my questions. Christian, on AUTO2, can you just give us a status update on the NG program there?
Christian Itin -- Chairman and Chief Executive Officer
With multiple myeloma, obviously, I went back and reengineered a new program, which is called AUTO8, and that program is slated to get back into the clinic second half of this year.
Biren Amin -- Jefferies -- Analyst
Got it. And then on AUTO4, thanks for the prior response. But if I look at some of the data with bendamustine, for example, in relapsed/refractory setting, I think there's some data out there that reports an OR of close to 30%; CR of about 20%, 25%; median DOR of about 3.3 months. Is that kind of like the bar that you would need to beat with AUTO4?
Christian Itin -- Chairman and Chief Executive Officer
I think you want to be above that. But you're right, that is currently what the bar looks like in that disease setting. That is sort of as kind of the best we can do for these patients at this point. So it's clearly one of the CR rate side, but it's clearly a very poor starting point.
Biren Amin -- Jefferies -- Analyst
OK. And then maybe just a question on AUTO3. How much data do we need to see later this year to move this program into pivotal? And, I guess, at what cell dose are you looking at? Greater than 150 million in cell dose? Or are you looking at the 450 million cell dose to make a determination on pivotal studies there?
Christian Itin -- Chairman and Chief Executive Officer
