Ladies and gentlemen, thank you for standing by, and welcome to Adaptive Biotechnologies Third Quarter 2020 Conference Call. At this time all participants are in a listen-only mode. After the speakers' presentation, there will be a question-and-answer session. [Operator instructions] I would now like to hand the conference over to your speaker today, Ms. Karina Calzadilla. Thank you. Please go ahead.

Thank you, Buena, and good afternoon, everyone. I would like to welcome you to Adaptive Biotechnologies third quarter 2020 earnings conference call. Earlier today, we issued a press release reporting Adaptive's financial results for the third quarter of 2020. The press release is available on adaptivebiotechnologies.com. We are conducting a live webcast of this call and will be referencing today's live presentation that has been posted to the Investors section on our corporate website. During the call, management will make projections and other forward-looking statements within the meaning of federal securities laws regarding future events and the future financial performance of the company. These statements reflect management's current perspective of the business as of today. Actual results may differ materially from today's forward-looking statements depending on a number of factors, which are set forth in our public financial statements with the SEC and in the 10-Q filed today. In addition, non-GAAP financial measures will be discussed during this call and a reconciliation from non-GAAP to GAAP metrics can be found in our earnings release. Joining the call today are Chad Robins, our CEO and Co-Founder; Julie Rubinstein, our President; and Chad Cohen, our Chief Financial Officer. In addition, Harlan Robins, Adaptive's Chief Scientific Officer and Co-Founder will be available for Q&A. With that, I will turn the call to Chad Robins. Chad?

Thanks, Karina. Good afternoon everybody and thank you for joining us on our third quarter 2020 earnings call. Once again, I want to thank all of our Adaptive employees for their unwavering dedication and flexibility over the past several months. During the quarter, our financial performance was solid and we made substantial advances across all business areas. These results continue to validate the value of our immune medicine platform as a clinical product development engine. On Slide 3, let me walk you through some of the key highlights for the quarter. We reported revenues of $26.3 million, representing 25% growth versus prior quarter and 1% growth versus prior year. Related to our research business, we are working with two top tier vaccine developers to use immunoSEQ T-MAP COVID in a subset of patients from their late stage trials. This is encouraging as we strongly believe that measuring the T-cell immune response to vaccines is necessary to understand durability of the immune response. In clinical diagnostics, clonoSEQ test volumes grew sequentially 28%, and we also launched clonoSEQ for patients with CLL. For our diagnostic pipeline product, formerly known as immunoSEQ Dx, we are pleased to announce the new brand name is T-Detect, representing the power of T cells to detect disease. Today, we released top-line results showing that T-Detect outperform serology to confirm past infection, which further supports the upcoming launch of T-Detect COVID. In addition, we have also identified a clinical signal for Crohn’s disease, demonstrating a consistent cadence in our R&D pipeline. And last but not least in our drug discovery business, we are extremely encouraged that we have successfully identified two highly potent neutralizing antibodies against SARS-CoV-2, which we believe to be best-in-class. Our neutralizing antibody work is another proof point of the potential of our immune medicine…

Thanks, Chad, and thanks to all of you for joining us today. I want to echo Chad's thanks to our incredible employees. It has been another busy and successful quarter during an uncertain time. Turning to Slide 7, I'm going to start with our life science research business. Our research business, although the most severely impacted by COVID-19 last quarter, has experienced some encouraging uptake during the third quarter. In addition, as we continue to execute on our pipeline for future revenue year-to-date bookings have more than doubled from this time last year. That said sample arrivals continue to vary month by month and recovery is at a slower pace than our clinical business. Additionally, we are still seeing delays or cancellations of clinical trials and other disruptions impacting predictability in the business. We are tracking this trajectory closely in light of rising cases in recent weeks. This quarter, we have made great progress driving adoption of our upgraded immunoSEQ RUO KIT. We have signed 24 new Core Lab partnerships with well-respected labs at institutions such as MD Anderson, Fred Hutchinson Cancer Research Center, and the University of Pittsburgh among others. These Core Labs will purchase our kits and offer immune sequencing to their internal network of researchers in their institutions enabling academic core labs as centers of excellence with our gold standard immunoSEQ RUO KIT is expected to set the foundation for long-term growth going forward. We have also made significant progress with immunoSEQ T-MAP COVID. We launched this product extension in August for vaccine developers to accurately and reproducibly measure the T-cell immune response to vaccines and track the persistence of that response over time. We hope to be able to answer many outstanding questions about durability and safety and potential differences in efficacy, across patient subgroups. Our…

Thanks, Julie. Turning to our financial results on Slide 12, total revenue in the third quarter was $26.3 million representing a 1% increase from $26.1 million in the same period last year and a 25% increase quarter-over-quarter. Our revenue mix for the third quarter consisted of 43% of our revenues coming from our sequencing category and 57% coming in from our development category sequencing revenue in the third quarter was $11.3 million representing a 3% decrease from the same period in 2019, but a 41% increase quarter-over-quarter. This year-over-year decrease was primarily driven by a $1.9 million drop in revenue generated from our biopharma partners partially offset by a $1.4 million increase in revenue generated by our clinical customers. Clinical sequencing volume increased 58% in the third quarter 2020 to 4,023 clinical tests versus last year, as we saw cancer centers continue to open up and patients returned to regularly scheduled MRD diagnostic testing. Testing volume increases in Q3 reflect a normalization of volume growth after a Q2 slowdown impacted by COVID research. The sequencing volume, which includes sequences reported to both our biopharma and academic partners decreased by 38% to 6,541 sequences from 10,618 sequences in the third quarter 2019. The decrease primarily reflects the ongoing challenges we recognize as many of our biopharma and academic customer centers remain operating at a lower capacity or in some cases shut down due to COVID. In terms of our expectations for the balance of the year, we expect our research business volume to grow at a modest pace due to the headwinds discussed above. And on our clonoSEQ diagnostic business our expectations are for continued growth versus the third quarter on an assumption of more normalized testing patterns for MRD. Development revenue in the third quarter grew to $15 million, up…

Thanks, Chad. At Adaptive, you have many exciting upcoming milestones in the next 12 to 18 months on the commercial and development fronts across all areas of the business listed on Slide 13. We are more confident than ever in our value proposition as we continue to deliver on our promises and demonstrate the capabilities of our platform. With that, I'd like to turn the call back over to the operator and then open up for questions. Thank you.

[Operator Instructions] Your first question is from Tycho Peterson of J.P. Morgan. Your line is open.

Hi, good afternoon. I'll start with Amgen now that you've handed over the antibodies, just latest thinking on timelines for them any chance of finding other candidates to pass along. And then I guess most importantly given what we saw from Pfizer yesterday with a 90% efficacy on the vaccine, does that change your view on the monoclonal antibody opportunity at all around COVID?

Yes. Hi, Tycho. Let me start with the final question. And I'll reiterate something I said in the speech is that, first of all, like everyone we're thrilled that there's a vaccine that has potential to have a widespread efficacy. That being said we think COVID is endemic in the population and that people are going to get sick for a long time to come unfortunately. Therefore having therapeutic solutions is going to be part of the patient treatment paradigm and we do feel that that kind of first wave of therapeutics while showing limited efficacy have a pretty significant room for improvement. And therefore kind of standing up a platform and delivering antibodies with superior performance characteristics, which we believe have superior performance characteristics, we think are going to have hopefully a place to kind of be part of the solution. That being said, so we handed over our data packages to Amgen. And to the question of whether we have additional antibodies, we do. We're continuing to kind of characterize and synthesize and put them together to see the synergy between – to be between the antibodies. And we're going to hear back from them relatively soon. Obviously a lot of factors from their perspective go into making this decision as well, which are beyond our control and we'll see where we land. But as you know, we also have many pharma partners out there and we'll be talking to them as well if Amgen elects not to move forward.

Okay. And then on the antigen map, a couple of moving pieces here, live the time lines are kind of pushed out relative to, I think, what you'd said last quarter with a year-end filing last quarter. So can you maybe talk to the delay there? And then I didn't hear any much celiac, has that kind of dropped off on the priority list?

Sure. This is Julie. Hi, Tycho. Just to clarify in case there was confusion the Lyme disease is moving forward. We had always anticipated launching Lyme at the end of 2021. We in fact anticipate launching Lyme a little bit earlier than that because we will bring it up in a CLIA environment and we'll prepare the FDA filing towards the end of next year. So the commercial implications and the commercial launch of Lyme disease is in fact a bit earlier than initially planned. Celiac is still in what we call stage four of our five stage R&D pipeline. We have an early signal there. We continue to study it further. The signal in Crohn's disease is particularly strong and something that we're really excited about, but we continue to assess celiac and lots of other disease states as well. I would say that we learned a lot from the speed with which we characterize the T-cell response to COVID-19 this year. And that's actually helping to expedite the R&D pipeline for many other disease settings. And we expect to announce clinical signals at a faster clip over the coming quarters.

Okay. And then just one last one before I hop off, the UK vaccine task force had a T-cell tender. Are you able to talk about that process I think Oxford, but are you able to talk about how that played out in your-end?

I have not – we did not participate. I am sorry. Chad?

I can tell you we're in conversations with Oxford, but we can't comment on the process.

Okay. Fair enough. Thanks.

Your next question is from Derik de Bruin of Bank of America. Your line is now open.

Hi, good afternoon.

Good afternoon.

Hi. Could you talk a little bit, I mean, how do you see the T-Detect COVID rolling out in 2021 as more people get vaccinated? And I guess, do you see more people getting tested to see if they have a memory T-cell response on this. I'm just sort of curious in terms of like how do you ultimately see this getting carried out.

Sure. So we see this rolling out in phases over time. We're essentially starting with an indication to confirm past infection. And we believe there's actually quite an appetite for among people knowing whether they had COVID-19 and also participating in non-market research to contribute to really understanding immunity through the T-cells and that is really guided by the T-cells. We think that over time, the question about immunity from both a natural infection from the virus as well as vaccines is going to be – continue to be important over time, particularly the duration of immunity even in a world where some people are vaccinated and some people aren't and people are still getting infected and we haven't been able to fully contain the disease. We do believe that really understanding where you stand remains important. And it's also important for employers and public health surveillance organizations who are responsible for understanding the status of the organizations they're responsible for. In the long-term, what we're really seeing is that there's actually so much sequelae from COVID that can last quite a long time and a large percentage of people who get COVID are in fact asymptomatic and never knew they had it, but yet months later or perhaps over the next couple of years, we'll have lots and lots of people, hundreds of thousands of people with ongoing symptoms. And when they go to the doctor, one of the first questions that I think they'll be asked, or one of the first things we're going to have to find out is if you've had a COVID infection given this range of long-term symptoms. So we do see an evolving value proposition over time again starting with past infection, confirming past infections, participating in non-market research, understanding immunity and how understanding the duration of that immunity exists in a changing world, that's getting ever more complex with vaccines. And then over time, I think, it's just going to become part of life. And when T-Detect down the road is able from the simple blood test to tell you everything that your immune system has seen or is currently seeing, it will include COVID.

Great. That was a good answer. And I have just two quick follow-ups. I guess, how do you think about your commercial launch? And how do you expect to commercialize this and I think the Lyme test in the CLIA setting. I mean that you don't have a sales force per se for the infectious disease. And how many of your – and what's the opening percentage of your academic customer labs, just sort of any sense on the academic environment and where that sits?

Sure. So, I'll answer the Lyme disease first. So similar to COVID, these are going to be very targeted launches. For COVID, it's largely digital marketing. For Lyme disease, we will be bringing on a sales force and also looking to partner for additional outreach as we move into the primary care setting absolutely. I think your second question was about the academic research business.

Yes, the academic research business. Just how many – your percentage of labs that are still or partially open versus the end of the last quarter? Yes.

Sure, sure, sure. We are seeing more labs opening there. We think the estimate we're working with and from research we're seeing in from our own experience about 70% of labs are open, but they're not fully staffed. So, there's a big – there's still a lot of change going on, but we do see more labs opening and we are getting more traction in that setting.

Great, thanks.

Your next question is from Tejas Savant of Morgan Stanley. Your line is now open.

Hi, this is [indiscernible] on the call for Tejas. Thanks for taking our questions. Could you just elaborate on the pricing strategy for Lyme going this off pay concierge service route? Would it be discounted versus the earlier ASPs you had talked about in the past?

Sure…

I just want to clarify the question.

I think it's mixed two things. So the concierge medicine sort of target is really for COVID as part of our soft launch strategy as one group that we believe would be interested in offering T-Detect COVID to their patients. For Lyme, it's a pricing strategy that is separate from concierge medicine, just wanted to clarify that. In the initial research, we had done – we were hovering around a price range of $600 to $800 per Lyme test. We've done some further research that's showing us that it will likely be in the lower end of that range. And we're going to be entering into one more round of pricing research as we get closer to our CLIA launch towards later this year and we'll finalize the pricing at that time.

Got it. Thank you. And I have a follow-up, could you provide your current thinking on the OUS strategy for clonoSEQ? How does the IVDR process in Europe impacts you're thinking there?

Sure. So, absolutely. Our international strategy is evolving quite nicely. We started with a strategy of tech transferring the assay to select sites in select markets to begin generating data, which is a very important process of expansion internationally. By the end of this year, we'll have seven of those international tech transfers with our CE mark product. We are closely monitoring all of the IVDR compliance regulations and incorporating them into that product as we continue to advance those tech transfers.

Thank you.

Your next question is from Doug Schenkel of Cowen. Your line is now open.

Hi, good afternoon. Thank you for taking my questions. Just starting on your commentary on clinical trial cancellations, I think you have that in your prepared remarks, Julie. Just curious has this improved relative to last quarter. And are there specific indications where cancellations are more or less common?

That's an interesting question. So it's pretty much the same. I think if anything – there's studies here and there that are getting canceled, what we're seeing more often is that timing of sample collection and shipment is unpredictable. And it doesn't really seem to be more or less in any disease states.

Okay. And then another follow-up on commentary from your prepared remarks, I believe both in your commentary as well as in the really well put together slides. You commented on community hospital adoption. I'm wondering if that's driven by more commercial detailing and then kind of on the flipside your higher volume legacy accounts, have they resumed ordering at pre-pandemic levels?

The legacy accounts – hi, Doug. It’s Chad. The legacy accounts, some of them still are not back online, some of are kind of largest historical ordering accounts. We still have some that aren't back. However, the ones that are back are ordering, but I wouldn't say they're yet at pre-pandemic levels. As far as kind of the community, I do think the commercial detailing is contributing. It's still small, but good – but we've got a nice growth curve from the community based on the work that we've done in putting reps out in the community in the hospital setting.

Okay, super helpful. And one last one as was noted in the press release and earlier in this call, you guys are really well capitalized while operating spend increased Q3 to Q4. You still came in a smidge light of what we were forecasting. Now that could just be a function of our model, but I think the bigger higher level question is, are you holding back on growth investment at this point given uncertainties in the existing environment, or at this point are you now fully playing offense when it comes to R&D investment as well as commercial build-out?

Yes, so, Doug, we're fully playing – we're looking for ways to fully play offense, I should say in the sense that the T-Detect is a great proof-of-concept for the broader strategy that a single blood test can detect many diseases at the same time. And we're looking to accelerate spending to be able to prove out that concept and then commercialize kind of a broader base blood test to detect many diseases at the same time. Additionally, having stood up the – an antibody discovery platform, which is another extension of the immune medicine platform to discover kind of therapeutic opportunities. We are also kind of – we have a search and evaluation team and are assessing ways that we can continue exploring opportunities in the therapeutic space.

And just to add-on on top of that in terms of pressing our advantage, I mean, we did expand our operating expense line by about $5.5 million quarter-over-quarter from Q2 to Q3, up 44% year-over-year. You're going to see that re-reaccelerate in the fourth quarter, turning up closer to 50% year-over-year in terms of OpEx spend next quarter.

Okay. Super helpful. Thanks. Thanks team.

Thanks, Doug.

Your next question is from Salveen Richter of Goldman Sachs. Your line is now open.

Good afternoon. Given the Glaxo announcement, can you just comment on your BD strategy and the forward with regard to clonoSEQ and potentially other programs as well?

Sure.

Sure. So the Glaxo announcement is much like many of the previous MRD deals that we've signed with various pharma partners. And it remains an important part of our strategy for clonoSEQ. It's a big part of demonstrating clinical utility for the product. And so Glaxo is another one of those deals, although it is the second that we signed that pan portfolio. So some of the previous deals are specific to one asset, one compound, one drug for a pharma company. In this particular case, it's multiple drugs in development across the disease states. Moving forward, right now, most of our – the rest of our pharma work has been on the immunoSEQ side, but moving forward, we do see opportunities to move into diagnostic partnerships with pharma for T-Detect in the future, much like we've done for MRD to date.

And then with regard to T-Detect for COVID-19, what's the earliest that you would expect an FDA clearance or EUA? And then secondly, on the antibody here, could you just comment on the cocktail approach and the work maybe you've done there and you've mentioned superior performance characteristics. So how you think this is stacking up versus the antibody data that we've seen to date?

Sure. Hi, Salveen. I'll take the first question. We intend to file the EUA by the end of the year depending on FDA's kind of turnaround time. We could expect to have that. It's hard to predict when we could expect to have that, but I can say the engagement level has been extremely high and we've been – as we've gotten information continue to pass it along. So, hopefully, sooner rather than later, but that's FDA dependent. In relation to the synergistic capabilities of the antibodies, I'll turn it over to Harlan to answer that question.

Yes. So each of our antibodies separately in live virus neutralization has, as we said, where they were at 16 picomolar IC50 and 13 picomolar IC50, so just to put that in context each individually is significantly – neutralizes live virus at a significant lower concentration than anybody else's cocktail on clinical trials right now, but that's at least that we're aware of. But we know through what's called the pseudovirus neutralization assay that when we put the two – our two lead candidates together that we're getting another significant bump in fact somewhere between a third of the – approximately a third of the concentration of each individuals, when they're together will neutralize the live virus. So we expect, sorry the pseudovirus, so when we get the live virus version, we expect the cocktail to have a significant boost in performance over the individual's.

Very good. Thanks.

Your next question is from Brian Weinstein of William Blair. Your line is open.

Hey guys. Good afternoon. Thanks for taking the questions.

Hey, Brian.

Hey. So starting out on the T-MAP COVID product here, you guys have obviously said you expected some revenue in 2020, and you've now said that you have some vaccine manufacturers on Board. Can you just give us some idea on what we're talking about as far as what that revenue could be this year, and then what the model still is? Is it still sort of that flat fee plus the tech access fee that that you guys were talking about before? Is there any change that kind of how all that played out with actually signing these deals?

Sure. Thanks, Brian. So for the first couple of deals that we signed, some of that revenue albeit small will come in this year, it's a subset of patients from these ongoing trials. It is still – we're still tracking with the same model with a fee for service per sample price, plus the tech access fee for the antigen mappings. Although for some of the larger negotiations that we're in the middle of, they'll be a bit more bespoke given that there's tens of thousands of potential patients to be sequenced. But that is still the general approach absolutely.

And the idea between the subset of patients in these trials versus having this being used on all patients in the trial, what's the thought there and how does that expand over time?

So I think what's really important there is – there's a very critical set of samples that are necessary to understand the T-cell response and that is the set of patients who've been vaccinated who do, and then do not get the virus and to compare that difference between those, those, those populations of people. In addition to obviously those who didn't get vaccinated at all, and so we have these really nice subset, very well-characterized well group's studies underway where we're going to get to understand the differences between those populations and that is what's going to give us a really good signal to take into the larger studies and into new studies and next generation vaccine studies, where we have a potential correlate of protection that is very quantitative defined by the T-cells that map the SARS-CoV-2.

Got it. Thank you. And then on T-Detect COVID, the 97% versus the 77% for serology; what was the serology test that was used as the comparitor there?

Harlan, do you want to take that?

Yes. So we're – we'll have to get back to you on that, because it’s part of a bigger publication with our collaborators, but it's a EUA approved serology test and will also supplement that with additional serology tests from other manufacturers. So that's why we're not releasing it. It's going to be more than just one.

Okay. Great. And then last one for me on the Crohn's product. Maybe I didn't hear you say it. But you said you have a strong signal here. Can you just give us some idea what that means relative's kind of – what you've seen previously in terms of signal at this point for other applications. And then did you say what the next steps were and when we would actually see data on that?

Yes. Thanks, Brian. So we – the reason we're particularly excited about Crohn's is that with a relatively small study subset about 350 people, we're seeing a signal in sort of the same caliber as we were in the COVID case with that number of people to develop a signal, really, really high specificity. We're highly, highly convinced the T-cells that we've identified – T-cell receptors are specific to, just to Crohn's and therefore there's still a subset of patients that were – we need to expand to pickup all Crohn's patients, but we're, I would say that we're feeling as confident as we were at the same state as we were with COVID where we're now almost well in the upper nineties in sensitivity. But since we only have 350 patients so far, and there's a bunch of – a bunch of broader questions we need to ask, we need to collect much larger cohorts. And so we're in the process of doing that. We expect some of the bigger cohorts to come in the first quarter. And then we'll be publishing the results as – after we analyze and write-up the larger data set. So sometimes – and then publication always takes a little bit of time. Unlike the COVID world where you everything was done immediately and normal publication space, you have to actually go through a peer review before you publish. So it'll be a little bit of a delay on that relative, but it should be next year, for sure.

Totally understand. Okay, guys, thanks so much for taking the questions.

Thanks, Brian.

Your next question is from David Westenberg of Guggenheim Securities. Your line is open.

Hi. Thanks for taking the question. So does the Crohn's disease kind of mean that we're going to be looking at a GI panel in kind of the near future? And on the Crohn's disease, that seemed to come a lot faster than my expectations, at least, when you're finding these diseases, is there a serendipitous effect? Or is it really honed in on the beginning and on one hand, it's great, if you can just point and shoot, but I'd also think that maybe if there is some serendipity, you can come up with new stuff pretty quickly?

Yes. Let me answer the first question, David, and then I will I'll pass it to Harlan to answer the questions regarding signal generation. But in terms of, let me kind of reorient you to the strategy, which is first to go kind of disease-by-disease and single disease diagnoses. And the second part of the strategy is to go get a differential diagnosis for a patient that comes in with the same set of symptoms and for us to be able to definitively tell that patient and doctor through a rule in test, what they have. And then the third part of the strategy is to have, which is really what we're kind of focusing on in terms of the longer longer-term vision of a single blood test that can diagnose many diseases at the same time. So, as we kind of mentioned with celiac, Crohn's, absolutely, Crohn's, we believe, would be part of at least medium term as part of a GI panel where a patient would come in with a gastrointestinal symptoms, and we'd be able to tell them whether they have Crohn's or ulcerative colitis et cetera. So it's actually kind of where we are tracking. We understand this has been tried in the past, but with the sensitivity and specificity of T-cells, we believe that we can distinguish. Now Harlan, I'm going to pass you to discuss signal generation.

Yes. So we have a team that is – so we separated the world into infectious disease, cancer and auto-immune, and then we've added some other diseases that we didn't – I don't think inherently thought were immune mediated, but have now come to look like immune mediated. And then we went through and I would say, we've created a ranking system for all the autoimmune diseases. And for the ones in terms of unmet need, what we thought we know about the disease in terms of the immune response, how we would interact with pharma, all sorts of parameters. And then of course the size of the opportunity, and we've then – we have a team that goes out and searches for well-characterized data sample sets that from different repositories where we can start doing signal generation with already collected samples. This is, I think the big advantage of moving cellular immunology to a molecular assay as we can use samples that are stored in someone's freezer. And Crohn's was definitely high-up on the list in the auto-immune category. There's a bunch of others and for all of them, we've – are in the process of collecting samples, or we already have collected samples under the process of analyzing. So we're trying to just tick them off in a pre-specified order, according to our ranking system.

Great. Thank you. And then, I think this one's probably for Julie. An update on your thinking on T-cell therapies outside of oncology or partnerships in perhaps vaccines, any change of thinking there, maybe that's Chad, but I think it's Julie.

Well...

I'll answer that. And we are evaluating extensions of the therapeutic, the drug discovery platform to other areas, T-cell therapy, for example, an auto-immune and vaccine. The vaccine opportunities, we're looking at that both from an M&A perspective in terms of both talent and technology, and we're looking at it from an internal perspective is an extension of our capabilities. So we've got search and evaluation team out there looking and – when the time is right, we will reveal more information.

All right. Thank you very much.

Yes. Thanks, David.

Your next question is from Mark Massaro of BTIG. Your line is open.

Hey guys. Thanks for taking the questions. I guess, Chad, first question for you. Can you just share a little bit of the logic behind rebranding immunoSEQ Dx to T-Detect? And then as a follow-up, in context of Illumina buying GRAIL and Exact buying Thrive, does that at all change how you guys think internally about potentially packaging, some of the single test indications in T-Detect for COVID Lyme and Crohn's and other indications in the future, and perhaps bundling them together as one multi-cancer panel?

So let me answer the second question first. And so I think it's a really interesting question and I'm not sure it changes our thinking. But it's not multi-cancer panel, I would say multi-disease panel. But absolutely the goal is to have a multi disease panel, and we are looking at ways that we can accelerate that vision of one blood test being able to answer questions and diagnose multiple diseases kind of all at the same time. So yes, I would say, I wouldn't say necessarily that that changed our thinking, but that is our thinking. And then I'm sorry, Mark, I got – well the first question Julie, you can ask the first question.

T-Detect branding? Yes. I'll answer the T-Detect branding question. So when we initially started talking about the clinical pipeline immunoSEQ Dx, we thought it was really important to clearly communicate that the underlying chemistry for that future pipeline of diagnostics for multiple diseases, as Chad just described that it was really clear that, that was the same bread and butter immunoSEQ assay; the TCR beta sequencing assay, which is our absolute gold standard. Like as Harlan said, turning immunology into a molecular assay from blood, super scalable, we wanted to make sure that was really clear and that we were spitting out, the – all the T-cell receptors in a give him blood sample and then simply mapping those receptors to the antigens of disease that they see. And so that was the initial strategy, but of course, as a consumer test and as just a test with a brand that you can kind of get behind in a diagnostic setting, we thought that it was more important now moving forward to focus on the important role of the T-cells in particular and how the T-cell detects all diseases in the same way in the body. And so we hope that everybody understands that the underlying chemistry is the same as the immunoSEQ assay, but that going forward that, that sort of more attractive brand name of T-Detect really gives credence to what that test has the capability to do.

That's really helpful. Thank you. And then one of the other question is, is your clinical sequencing volume was quite strong, beat my estimate. Can you give us a sense for the number of repeat orders that were – that occurred in the quarter? And then can you comment to what extent the availability of blood testing is contributing to the top line?

You broke up there on your first question. In terms of blood testing, it still a pretty small component of our overall testing volume. I'd say it's significantly higher for indications like CLL, probably in the 60% range. And then almost rounding to zero with multiple myeloma, but representing a decent component of our ALL blood volume. But overall it's a pretty low sort of overall percentage of our volume. I'd say it's somewhere around 20% or so.

And Julia, he asked about what the – how repeat testing is contributing to our – in clonoSEQ as opposed to new testing, I presume?

Yes. Sorry, I couldn't hear. Your connection was garbled. Sure. So we are still – we haven't reported out yet. We wanted to give ourselves a little more time to cover the full length of – the full treatment cycle, the sort of duration of a treatment cycle for any given patient with any given lymphoid malignancy before we start reporting out on regular number of tests per patient. But we're definitely seeing somewhere in the two to three range for tests for patients. And we'll continue to report out as that date matures. And in terms of I think I commented in my script, we have about 685 new ordering HCPs this year. And those new ordering HCPs are taking a shorter amount of time to begin taking up a greater percentage of the order volumes in a given period. So whereas in the last quarter, I think we mentioned it was about – 8% of order volumes were from new ordering HCPs, now we're up to 16%. So we're seeing a shorter times ordering after signup of new accounts or a new HCP. I'm not 100% sure of that's what you were getting at, but I tried to answer the question in sort of two different ways.

Yes, thank you. And then if I can, one final one, is there any – strategy to kitting with Illumina and when do you think clonoSEQ could be available though a kitted solution?

Sure. So we contractually have the ability to do that with Illumina as I think you know. We continue to evaluate whether or not that – whether or not to do so and what the timing would be of that process. And that is given – what you just said, which is a really nice uptake of our service offering as a send-out test. And so we continue to evaluate. We are continually making upgrades to the assay, which would port right into a kit anyway. So the timing wouldn't be affected. It's really more of a commercial strategy at this stage.

Okay. Thank you very much.

At this time, there are no further questions. And I would like to turn it back to presenters for any further comments.

No further comments at this time. Thank you very much for joining today. I look forward to the fourth quarter.

Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
