first, we will expand disease by disease; second, we will enable non-invasive testing in the blood; and third, we will do study after study demonstrating clinical utility in each disease across multiple time points in the patient care continuum.Like the migration from analog to digital photography, clonoSEQ is massively changing the resolution with which we can see and count cancer cells.

We believe there will only be a matter of time until clonoSEQ is standard of care.Shifting to our diagnostic product in development, immunoSEQ DX, we are excited to announce that we have achieved an important milestone. We confirmed our first clinical signal, proving that we can read and translate how the Adaptive immune system diagnoses disease.

At the center of this discovery is our vast immunomics database, which we have used to train machine learning models to develop diagnostic signals. We have demonstrated this in Lyme disease and are making progress in other disease states.

This is all part of our vision to enable the early and accurate diagnosis of many diseases at the same time by reading the genetics of the Adaptive immune system. In collaboration with Microsoft, we are categorizing population wide immune responses to many possible diseases, a massive attractable data problem.

We already engaged in early discussion with the applicable regulatory bodies to scope out a potential path towards commercialization for immunoSEQ DX.Finally, in partnership with Genentech for our drug discovery pipeline, we are also advancing our therapeutic grade TCRs for cellular therapy and oncology.

And we continue to expect an IND filing for the product, targeting shared antigens in late 2020. To execute on our vision, we are strategically scaling our organization to move into this next phase of growth.

Looking ahead to the next 5 to 10 years, we are focused on harvesting the data from our platform to develop patient specific, immune-driven clinical products to recognize the open-ended growth story in front of us.

Our people and culture team, or PACT, is singularly focused on recruiting and retaining top talent to accelerate our progress against these ambitious goals. We have a mission-driven culture at Adaptive that drives commitment to each other and to our patients to achieve things that have never been done before.

As we continue to invest heavily across our platform, we are committed to retaining these core values that we believe are critical to our long-term success.I will now turn it over to Julie, who will walk you through more information on our immune-driven research and clinical products, after which Chad C.

will provide greater details on our financials.

Julie?.

Thanks, Chad. Starting first with life sciences research. We are continuing to make important progress across our research business as our partners expand their usage of our immuno sequencing products and services.

In particular, the biopharma community is increasingly using immunoSEQ for immune repertoire profiling, and clonoSEQ for MRD monitoring in clinical trials. Since the beginning of 2019, our assays have been selected by an additional 40 biopharma companies for a total of 165 partners to date.

As Chad mentioned, by the end of this year, we are launching an upgraded RUO kit for immunoSEQ that will work quantitatively with any sample type, including stored tissue samples. As the use of immuno sequencing expands across disease states, we are growing our sales and marketing team and seeking partners for global distribution.

As the industry continues to assess the inclusion of MRD as a potential surrogate or primary endpoint in clinical trials for blood cancers, it is increasingly important to have a standardized and highly accurate option for MRD testing in registrational trials.Of note, in Q3 we announced a global agreement with Amgen for the use of our clonoSEQ assay to assess MRD across multiple drug development programs in their portfolio.

This partnership exemplifies the growing role MRD testing plays in demonstrating drug efficacy in clinical trials. Under the terms of this type of agreement, we will receive annual development fees in addition to potential sequencing payments and regulatory milestones.Turning next to clinical diagnostics.

Starting with clonoSEQ, clinical test volumes during the third quarter increased 36% to 2,551 tests compared to the third quarter of 2018. clonoSEQ is currently used by more than 400 HEMOCs in over 130 institutions. Clinical test volumes are growing in line with our expectations just 9 months following CMS coverage.

Progress to date has been achieved by a small 14-person field force. As Chad mentioned, we have triggered an expansion in commercial resources in response to accelerated coverage to achieve broader market adoption over the next 18 months.

We aim to more than double our field team by January 2020 to support the growing demand for clonoSEQ across the U.S., and the need to expedite the account activation and workflow integration processes.

We are also ramping up our marketing efforts so that more patients are aware of the importance of knowing their MRD status.We are educating the clinical community about the importance of obtaining a baseline sample for every patient. This will enable us to perform regular longitudinal MRD monitoring over the lifetime of each patient.

Today, clinicians are already using the test to confirm response to therapy, determine disease burden before and-or after transplant, confirm complete remission by traditional methods and guide maintenance therapy.

To expand the use cases for clonoSEQ, we are continually generating data through biopharma partner trials, investigator sponsored protocols and a patient registry to curate real world evidence.With regards to lifecycle management, we are on track for our first label expansion with submission to the FDA by the end of 2019 for clonoSEQ to be used to monitor patients with CLL from blood samples.

Work is also underway to expand our current label from bone marrow to blood in multiple myeloma and ALL, and to extend utility to patients with NHL, also from blood samples. Moving into blood will be highly preferred by patients and significantly less costly to the healthcare system.

We are exploring product line extensions that may allow for greater access and utilization of our diagnostic products. To that end, we announced a partnership with Illumina to enable the development of in-vitro diagnostic test kits for local labs.

We are committed to ensuring that patients have access to the best tools available to monitor their disease, and while it is still early days, we are confident that clonoSEQ will become the standardized MRD monitoring tool that clinicians will use to manage their patients.Turning now to our clinical diagnostic pipeline product, immunoSEQ DX.

This product is intended to diagnose disease based on the T-cell response to disease specific antigens, which we are calling a TCR signature. Each disease will have a different TCR signature, which we will identify and continuously improve by leveraging our immune medicine platform and Microsoft's machine learning expertise.

To launch this product in 2021, we set out to confirm at least one clinical signal by the end of 2019 to take into clinical validation in 2020. This signal confirmation has been achieved in the acute line disease setting from two independent retrospective 200 plus patient cohorts.

In both of these studies, we compared to standard of care, which is two-tiered serological testing. Our data shows a reduction in both false positive and false negative rates compared to standard of care.

In each patient cohort, we identified T-cell receptors that are over represented in patients with acute Lyme disease, whose cases have been clinically confirmed.

We intend to continually improve the diagnostic sensitivity of our test by identifying more line specific receptors over the next year as we collect additional patient cohorts and run our registrational clinical validation study.

There are approximately 300,000 newly diagnosed patients with Lyme disease each year in the United States and over 3.5 million tests run. We believe that detecting Lyme disease based on the expansion of line specific TCRs in the blood can significantly increase the accuracy of detection of this disease.

This signal in line de-risks the science behind immunoSEQ DX.We also continue to progress in other disease states that we have discussed such as celiac disease.

In October, we opened a research study for 1,000 volunteers who believe they may have celiac disease, and we plan to sponsor several other such studies in additional disease states in the near future.

We are now expanding our commercial team for immunoSEQ DX, and working with the FDA to define our validation protocols necessary to bring this product to market.Turning now to drug discovery. Our partnership with Genentech to use our TCR discovery and screening process to develop cellular therapies in oncology is progressing well.

As previously discussed, we are focusing on the development of shared cellular therapy products using our version of off the shelf TCRs against prioritized shared antigens. In Q3, we contributed significant resources to the generation of data packages on TCRs against many antigen targets.

From these data packages, Genentech is prioritizing TCRs for cell therapy product development with the goal of the first IND filing in 2020.

We are also continuing to make progress with Genentech on the development of a personalized cellular therapy product, where we plan to identify in real time the TCRs that are specific to each patient's tumor.In sum, we are beginning to gain traction on all fronts as we execute against our commercial products and advance our clinical pipeline.

We are confident in our ability to leverage our immune medicine platform to bring high margin, patient specific immune-driven products to market.With that, I will now turn the call over to Chad C. for more details on our financials.

Chad?.

Thanks, Julie. Turning to our third quarter 2019 financial results. Total revenue in the third quarter was $26.1 million, representing an increase of 52% from $17.2 million in the same period last year.

Our revenue mix for the third quarter consisted of 45% of our revenues coming from our sequencing category and 55% coming from our development category. During the period, we recognized $2 million in revenue related to a milestone payment from a biopharma partner, which I will discuss in a moment.

By comparison, we recognized $6 million in milestone revenue for the same period last year.Sequencing revenue in the third quarter was $11.7 million and grew 38% from the same period in 2018.

This increase was primarily driven by growth in revenue generated from our biopharma and academic customers, and really the sequencing volume, as well as growth in revenue generated from our clinical customers.

It's important to note that we recognized revenue in our sequencing revenue category when sequencing results or clinical test results are delivered to our research and clinical customers.

Research sequencing volume, which includes sequences reported to both our biopharma and academic customers, increased by 25% to 10,618 sequences from 8,466 sequences in the third quarter 2018. Separately, clinical volume increased by 36% to 2,551 clinical tests from 1,879 clinical tests in the third quarter 2018.

Development revenue grew to $14.4 million in the third quarter, up 65% from the same period last year.

The increase was primarily due to amortization of the $300 million upfront received in February from our Genentech partnership, partially offset by a decrease in regulatory milestones recognized in the third quarter of 2019, as compared to the third quarter of 2018.

Cumulatively, we have recognized approximately $26 million from the upfront payment in 2019, while approximately $274 million of the original $300 million upfront is still categorized as deferred revenue.As previously mentioned, we received a $2 million milestone payment from a biopharma partner with whom we had collaborated with on the use of clonoSEQ to expand their drug label.

We are excited to have been part of helping our partner achieve this milestone, and as of quarter end under our customer contracts, Adaptive may receive up to $129 million in MRD-related milestones over time as certain regulatory approvals are obtained.

It is important to note though that the timing, extent and certainty of achieving MRD-related milestones is hard to predict and not within our control.

However, these milestones do signify the growing importance in the use of NGS, MRD technology and specifically clonoSEQ in the monitoring of patients in clinical trials, and the importance of determining the efficacy of drugs in the regulatory approval process.Shifting now from our revenue to our operating costs.

Total operating expenses for the third quarter of 2019 were $44.1 million, representing a 68% increase from $26.3 million in the same quarter last year. Working down our operating expenses, cost of revenue was $5.6 million during the third quarter 2019, compared to $5.4 billion for the third quarter last year, representing a 4% increase.

Research and development expenses for the third quarter of 2019 were $20.5 million compared to $9.8 million in the third quarter of 2018, representing an increase of approximately 110%.

The increase was primarily attributable to additional cost of materials and allocated production laboratory expenses relating to supporting our TCR drug discovery efforts, TCR antigen map development and clonoSEQ efforts, as well as an increase in personnel costs.

Sales and marketing expenses for the third quarter of 2019 were $9.1 million compared to $6 million in the third quarter of 2018, representing an increase of approximately 51%.

The increase was primarily due to additional personnel cost to support our expanding business.General and administrative expenses for the third quarter of 2019 were $8.5 million as compared to $4.7 million in the third quarter of 2018, representing an increase of approximately 79%.

The increase was primarily driven by increase in headcount and costs associated with being a public company. Both net loss and net loss attributable to common shareholders for the period was $14 million or $0.11 per basic and diluted share, compared to $8.3 million or $0.66 per basic and diluted share in the third quarter of 2018.

Our earnings per share are based on approximately $124.3 million and $12.6 million weighted average shares outstanding for the third quarter of 2019 and 2018 respectively. Adjusted EBITDA for the third quarter of 2019 was a loss of $12.7 million compared to a loss of $5.1 million in the same period of the prior year.

We ended the third quarter of 2019 with approximately $709 million in cash, cash equivalents and marketable securities, and we had no debt.Moving on to our outlook for 2019.

We are raising our 2019 revenue outlook and now expect full-year revenue to be in the range of $82 million to $83 million, representing growth of 48% at the midpoint of the range over 2018. This compares to our previous expectation of $78 million to $81 million for the full year 2019.

The increase in our guidance range contemplates the receipt of the $2 million milestone payment that was not included in our prior revenue expectations, as well as an acceleration of development activities related to our Genentech partnership to the third quarter and the temporary decrease in our academic business expected for the fourth quarter as many investigators are choosing to wait for the new version of our assay to come online around year-end.

As we turn the corner to 2020, we are incredibly excited about the future, and we look forward to providing our outlook for 2020 when we report financial results for the fourth quarter of 2019.With that, I will turn it back to the operator to open it up for questions..

Thank you. [Operator Instructions] Your first question comes from the line of Tycho Peterson of JPMorgan. Your line is open..

Thanks. Another good quarter, especially on the development services side. Is this the new baseline going forward? And is that really just the work progressing faster than expected..

Thanks, Tycho, for the question. Just reiterating the comments that we just made, there was a big push to deliver a number of data packages in the third quarter. So that resulted in a uptick of the resources consumed as part of that partnership.

We don't expect that level of investment to be at the same area in the fourth quarter, and therefore, it likely will pick up again in 2020. But in the fourth quarter, it'll be -- development revenues associated with partnership will likely level off..

And then thinking a little bit about pipeline, I guess starting with the label expansion for CLL for clonoSEQ and blood by year-end, can you just talk to how you think about that process? How much risk there is? And then as we think about expanding multiple myeloma and ALL from bone marrow blood, how do we think about the timeline for those as well? I know you've talked about in the future, but wondering if you can....

Sure. Thanks, Tycho. For CLL, we are confident in our data and we're confident that we'll be submitting by the end of this year. So obviously, there is always risk when you submit to the FDA in terms of the timeframe as to which we receive approval.

Technically they have a six-month timeframe in which to grant us marketing approval for the CLL label expansion, but we are confident in our data. As for ALL, you talked about ALL in the blood. We are also progressing nicely.

We haven't yet talked about our timeframe for submission on that yet, but we are progressing very nicely on the data and we expect to have a filing in 2020..

And then on the Microsoft antigen map, you mentioned early discussions with regulators. Can you just talk to the nature and tenure of those discussions and how far behind are the other signals like celiac and ovarian? You mentioned you're still working on them, so....

Hi, Tycho. Yes so we're actually progressing fairly nicely on celiac and we're feeling quite good about the results. It's a little bit behind where we are with the line where we got the confirmation in two independent studies, which allowed us to feel confident in announcing it.

As far as other signals go, we're moving on a lot of different fronts, which we'll be bringing up in the future. And then in terms of FDA, we've had multiple meetings now with the FDA.

And we're -- this is going to be a bit of a process because this is new to them and new to us, and they are showing significant interest in working with us and have been -- and I think are going to be a great partner for us going forward..

Okay.

And the last one, any impact from the New York approval back to clonoSEQ here that you've got in August in terms of volumes this quarter, or will take a little while for that to ramp up?.

That will take a while to a little while to ramp up, but we should see that start to ramp in 2020.

Matter of fact, I was just in New York last week visiting the New York institutions, and a lot of them are in that kind of first stages of account setup and workflow and then the next phase will be HCB training, but we should see the volume start to ramp up from the New York institutions in 2020, but it hasn't yet been reflected in this quarter..

Okay. Thanks..

Thank you. Your next question comes from the line of Derik De Bruin of Bank of America. Your line is open..

Hi, good afternoon..

Hey, Derik..

Hey.

Can you confirm specific what the MRD clonoSEQ revenues were for the quarter?.

So, Derik, we haven't provided any discrete numbers in terms of our ClonoSEQ revenues, but we're consistent with what we said in the prior quarter. Those revenues represent just under 10% of our total revenues..

Got it.

And I guess can you talk a little bit about how you're sort of thinking about the ramp in that product? And I mean I realize you're doing the onboarding and bringing on people now, but could you sort of talk about some of the work you're doing in terms of sales and marketing? How long you think before you'll start to see the acceleration in that product?.

Sure, Derik. Really, we're expected to be nine months into our commercialization efforts with having a 14-person field team in place.

As we mentioned, we've been to date largely focused on account-contracting, workflow integration and HCP training, and we're just starting to turn our attention to demand generation for the first two indications in ALL and multi myeloma. And we do expect to see some acceleration in growth, even as early as the Q4 of this year.

Additionally, so we're doubling our sales force. We're expanding our medical team in response to the accelerated coverage we got with 165 million lives, and I think together with the expansion of CLL into the blood, we're poised for 2020.

But as we talked about coming out in the IPO, we expected this to be an 18-month timeframe and the real inflection to be hitting in 2021, where we see clonoSEQ taking a meaningful portion of our of our total revenue trajectory.

But we are significantly, in addition to the sales force, ramping up our efforts not only in medical, but also in marketing to the patient population as well in terms of knowing their MRD status. And the final point is, I mean it's really a two-part component.

One is to get an IG sample for every patient, and then two this land and expand strategy where we find a time point for each patient that a use case for each patient and then --each clinician to then monitor more and more for each patient once they once they find kind of their initial time point..

Great, that's really helpful. And then just one final question. So, appreciate the update on the Lyme disease just some size of the market there. And also just curious how many signals or what do you deem is enough signal to move forward.

I mean I think there is sort of a question of at what point do you sort of think you're saturating the number of antigens that are out there.

So it's really a question of like when do you think you've got enough signal and sort of a question is like, are there going to be antigens, are there going to be false negatives out there that you're going to miss because you're not screening enough T-cells?.

Great, thanks. I'll answer first the question about commercialization and then I'll pass to Harlan who can answer some questions about --sort of size of the signal that we feel we need to have. So, as you know, we just received our first signal.

And I think right now we're most excited that that this significantly derisks the science, that's triggered our motion now to put our commercial team in place for this immunoSEQ Dx product. I would say we're currently assessing the commercial landscape for Lyme as well as other diseases, including those that we've discussed in the past.

And so as more signals get confirmed over the coming months we will solidify our commercial path forward..

Hi, so the signal that's needed for us to move forward is really driven by the present diagnostic and whether or not we can, we can improve clinical care by having a superiority in some dimension and that we're, and of course that we're confident that our signal is truly what we think it --that we've confirmed in multiple datasets and feel confident that it is what it is.

However, and the total number of T-cell receptors in the whole population that are specific for any given disease specific set of antigens is in the well into the millions, 10s of millions, some very, very large number.

And the number that we've found to date in any given disease that have generated our diagnostic is or is in the hundreds, thousand.So the point is, we're only seeing a small fraction of immune response and that's already sufficient to be considerably better than standard of care and certainly in Lyme disease.

And so the point is, is that with our partners, Microsoft, we have a machine learning algorithms that we're also discussing with the FDA, so that we are able to have a self-learning diagnostics. So we can discover more and more of those T-cell receptors that we go and continually improve our diagnostics..

Great, thanks for the clarity..

Thank you. Next question comes from the line of Doug Schenkel with Cowen and Company. Your line is open..

Hi, this is Sean [ph] on for Doug. Thanks for taking my questions. You mentioned ClonoSEQ because is at 165 million covered lives, which I believe is consistent with last quarter.

Could you provide an update on what percent of payer contracts have been implemented at this point? And I think on the last quarter's call, you said it would take one or two quarters probably to have all those payer contracts implemented. Is that still the thinking or put differently. Has this been going as planned. Thanks..

So, yes, it's been going as planned and we are in negotiations to convert those medical policies into contracts now. We expect to, first, some of the first to hit towards the first half of 2020 but discussions are progressing as planned..

Okay, great. And maybe a question for Julie on the Lyme disease.

I may have missed it, but did you reveal the details of the planned clinical validation study in terms of its size or how long it will take in order hit the planned launch in 2021?.

Sure. We are discussing that in our conversations with the FDA to determine the actual protocol. But we do believe it can be enrolled and fully completed in 2020..

Okay, great. And then maybe one last one for me is how does your sensitivity and picking up MRD and blood for the CLL indication compared to competitors, which I believe are only indicated bone marrow..

Yes. So we have --it's highly disease dependent, the tentative date of our assay is really related to the denominator, which is how many total sales we're looking at. So, realistically, the sensitivity our assay is identical in bone marrow and blood but the actual disease burden is slightly different in bone marrow and blood.

For CLL, they are actually fairly similar, so our sensitivity in blood is better than a less sensitive technology is in bone marrow, which is really which is why we think we'll be able to ship the whole field to blood. So that's, by the way, 100 million cells is what -- FDA approved..

Thank you. Your next question comes from the line of Brian Weinstein of William Blair. Your line is open..

Hey guys, thanks for taking the question. Recognizing that you guys are making a lot of investments in sales force and expansion of menu on ClonoSEQ.

Can you talk a little bit about how you expect to the typical timeline to play out from sort of introduction to an account to convincing the account to be thinking about MRD testing with ClonoSEQ to then having them be kind of fully up to speed, so is as we hear about more accounts coming up, what is that kind of general timeframe for them to just sort of ramp.

How are you thinking about that?.

Sure. Hi, Brian, thanks for the question. So this year it on average takes about 9 months to sign on an account and that includes all of the contracting, account activation and HCP training, we anticipate tightening that up now as we progress and as we brought in the field force as well.

And then within an account, the average time it takes for an ordering clinician to get to their fifth patient is somewhere between two to three months. So that gives you some sense of timing. We're learning a lot more as we penetrate further into the market and we expect those timelines to tighten as we, as we expand..

Great. And then can you talk a little bit about the institutions where you're getting the most traction academic large IDNs community.

Just where is this being received most favorably today and where do you need to do the most work ?.

Sure. So we've targeted a couple of hundred of the Tier 1 institutions. We did a quite a large and detailed landscape of all the institutions in the United States and that's really where our main focus has been and we're penetrating quite well in those Tier 1 mainly academic or larger institutions.

In 2020 we anticipate continuing to focus in those Tier 1 institutions, but also beginning to penetrate the Tier 2 as we move closer towards the community..

Great. And last one for me, I recognize you'll give formal guidance in the beginning part of next year. But just as we're thinking about 2020, are there certain considerations that we should be thinking about that, I hate to use the word puts and takes.

But are there certain things that we should be considering as we build out our models, a little bit more finally, for next year?.

Yes. So, we will give will give the formal guidance on the next quarter's call.

I would just say that 2020 will be still a pretty heavy investment year for us, as we think about the broader opportunity the applicability of [indiscernible] across many disease types as we continue to further our development relationship with Genentech and continue to press into the market with our ClonoSEQ clinical product which is likely going to involve significantly heavier lift from us, from a sales and marketing perspective..

Okay, thank you..

Thank you. Your next question comes from the line of David Westenberg of Guggenheim Securities. Your line is open..

Hi. thanks for taking the question. So [indiscernible] being able to send out much of an issue, kind of asked another way, do you anticipate the adoption of the IVD kit or the launch of the IVD kit to really increased traction in ClonoSEQ..

Hi David, I would say there are certain institutions that don't do send out tests. But I would also say that the many institutions that originally said, hey, we don't do send out tests, as MRD monitoring and in particular NGS MRD monitoring with ClonoSEQ becomes more and more known that is we're already seeing that start to change.

So as we, as we get more and more covered lives under medical policy and under contract, the kind of the barriers are being removed for clinicians to be able to send our tests. The other thing that we're working on is getting on test menu and working on kind of workflow and integration.

And as we have better and better examples and have an easier path to workflow and integration having done this now for the past nine months, we can go in with essentially kind of a menu of here. There are several ways that we can kind of work with you to send out a test and here's us working in different institutions..

So all right, thank you. And then just kind of continuation of Tycho's question about the conversations with the FDA in terms of, I mean of CTX are there. Have they brought up maybe any sort of like comparative Technologies or pathways.

For example, maybe diagnostic imaging with like maybe facial recognition software and it's not necessarily facial recognition, but that would kind of work at it iterative process that could go on, just any kind of help to maybe think about the way FDA has looked at other kinds of projects that have a similar kind of concept of, of learning as you go, kind of methodology?.

So the, the FDA wrote a really nice white paper that describes their policy position on this. It's not --I shouldn't say that really their policy position, but it's a, it's a white paper that was both looking for input and trying to establish their policy on this.

They have one, I think they have one approval to date that they're moving that they've already moved forward on. So but there the white papers should be quite informative. It's really well written and really lays out how they're thinking about how to use machine learning to have self-improving diagnostics..

Thanks. And if I could squeeze in just one last question for Chad on gross margins went up quite significantly. I mean basically sequencing revenue itself went up by about $3 million year-over-year yet. Cost of goods sold went up by about 300,000.

Is there something that's contributing to the increase in COGS is that maybe essentially currency, as we go forward more payer adoption, should we expect maybe an increase in COGS?.

Some of that relates to just overall scaling that we're doing in the lab.

So over time, we'll continue to engineer our test to bring down those costs, but others are specific really to the quarter in which we saw a mix towards our less costly immunoSEQ tests as part of that sequencing component of our revenues in the current quarter, but hopefully the goal is to drive down those costs over time.

And I think that's what you're seeing, when you look at comparatively our sequencing the cost of our sequencing revenues year-over-year for the 3rd quarter..

Thank you very much..

Thank you. Your next question comes from the line of Amanda Murphy of BTIG. Your line is open..

Hi, thanks. Some follow-up questions, I guess first on the conversation just around shift to blood.

There has been some data, I think recently some of the some to abstract and now that have looked at use of ClonoSEQ in trials and I realize this is not sort of a real world setting per se but there is just kind of a give and take between sensitivity and sampling meaning getting enough cells in the sample to get [indiscernible] sensitivity.

So I just was curious how to think about that. Moving forward, especially as you get into more of a clinical setting and getting the consistency of kind of the blood sampling draw stringency if you will..

Yes. So good question. So we have been consistently improving our extraction capabilities so that we can optimize removing the DNA that we need -- the concentration that we need to be able to consistently get at the that deeper level, we're actually acquiring enough sample to get to in a million is pretty standard.

There is a standard bone marrow or a standard blood, should have enough cells to get there on a highly consistent basis. So we see this as a temporary. But I think if not completely solved we're almost completely solved at this point..

Got it. And then just two quick modeling ones. So you talked about some academic weakness, I think in Q4, and then also obviously, I think from a seasonality perspective, everything is clinically, you may have a stronger Q4 just with the kind of typical running through sort of deductibles.

So when I guess everything about modeling ClonoSEQ and mmunoSEQ and then ASP dynamics, so trying to figure out how to think about those trends into Q4 volume and ASP, I guess more ClonoSEQ and its really very academic split between multiple different products..

Yes. So it will be just sort of at a high level, we'll continue to see growth in clonoSEQ revenue going into the fourth quarter and corresponding volume growth. So those are our expectations.

Second is we'll continue to see growth in our biopharma sequencing revenue as well as specifically, we've seen historically over the past many years, a lot of seasonality -- peak seasonality in the fourth quarter as a biopharma partners and sort of spend through their allocated budgets as well. So that will come into play.

Again this year at least was our expectations, and so I think the academic softness related to just the wait and see approach in terms of adopting our new assays and new kits that should come online more in the first quarter and through the rest of 2020 and we're seeing just a slight pullback in the fourth quarter relative to that academic business.

And I think, I hope that answers your question..

Yes, okay. And just another quick one on the milestone side, you talked a little bit about some level of pull forward with Genentech, but I guess just in front of the IND. I'm not sure if you're willing or able to disclose, how this milestones might play out through the IND, so I'm assuming, they'll be IND-related milestones.

But is there anything else in front of that, that we should think about or any way to quantify what that might look like into the IND filing itself in 2020 before, thought there would be?.

As we said, we plan to file an IND by the end of 2020.

We can't disclose yet what targets the IND is for nor do we have, really this is under Genetics control in terms of the timeline going forward, but there is a series of commercial and regulatory and commercial milestones associated both with the shared product and the private cloud product, that are with the Genentech deal and those milestones will fall in accordance with those products, both on commercial and regulatory milestones and again we don't yet have timing on those..

But there might be spend I guess between now and the IND --.

Say, that again. I didn't hear you..

I'm sorry --so it's not like it's going to be sort of derivative payments between now and IND filing, you're still kind of --.

No..

Yes. Okay, thank you very much..

Thank you. I am showing no further questions at this time, I would like to turn it back to you, CEO, Chad Robins for any further comments..

Thank you everyone and have a great evening. Appreciate it..
