Good afternoon.
My name is Emily, and I will be your conference operator today.
At this time, I would like to welcome everyone to the Exact Sciences Corp.
First Quarter 2019 Earnings Call.
(Operator Instructions) Thank you.
Megan Jones, Manager, Investor Relations, please go ahead.
Megan Jones - Associate Manager of IR
Thank you, Emily, and thanks to all of you for joining us for Exact Sciences' First Quarter 2019 Conference Call.
On the call today are Kevin Conroy, the company's Chairman and CEO; Jeff Elliott, our Chief Financial Officer; and Mark Stenhouse, President of Cologuard.
Exact Sciences issued a news release earlier this afternoon detailing our first quarter financial results.
This news release and today's presentation are available on our website at exactsciences.com.
During today's call, we will make forward-looking statements based on current expectations.
Our actual results may differ materially from such statements.
Descriptions of the risks and uncertainties associated with Exact Sciences are included in our SEC filings, which can be accessed through our website.
It is now my pleasure to introduce the company's Chairman and CEO, Kevin Conroy.
Kevin T. Conroy - Chairman of the Board, President & CEO
Thank you for joining us this afternoon.
The first quarter was a strong start to 2019 for Exact Sciences.
Cologuard's momentum gives us confidence we'll reach our long-term goal of at least 40% share of the U.S. colon cancer screening market.
During the first quarter, the Exact Sciences team screened the 2 millionth person with Cologuard, delivered $162 million in revenue and continued to build the foundation for future growth.
We are well positioned for success in 2019 and the long term.
Today, we will review our first quarter financial performance, full year guidance and discuss progress on our 2019 priorities.
Our Chief Financial Officer, Jeff Elliott, will now review our financial results.
Jeffrey T. Elliott - CFO
Thanks, Kevin, and good afternoon, everyone.
When discussing financial results, I'll refer to changes compared to the first quarter of 2018, unless otherwise stated.
First quarter revenue increased 79% to $162 million, and Cologuard test volume grew 79% to 334,000 completed tests.
First quarter Cologuard revenue per test declined $2 to $483 primarily due to mix shift towards commercially insured customers.
On a time line basis, our average Cologuard revenue per test was $480, an increase of $28.
First quarter Cologuard cost of sales was $128 per completed test, an increase of $4 through new capacity expenses partially offset by lab operating efficiencies.
We expect second quarter Cologuard cost per test to be in the low $130 range.
Bringing our new lab on in the third quarter will add about $5 to $10 of costs per test that we will work to offset with volume leverage and operating efficiencies.
First quarter gross margin was 73%, a decline of 130 basis points mainly due to capacity expansion costs.
First quarter operating expense totaled $187 million, slightly above our guidance due to higher revenue and the corresponding Pfizer service fee.
Selling and marketing included the Pfizer service fee of $19 million, which was about $4 million more than we had assumed in our guidance.
G&A included additional personnel and IT investments to support the Epic project and other IT initiatives.
R&D increased primarily due to our pipeline initiatives, including expanding Cologuard's label and Cologuard 2.0.
We expect operating expense to increase by $6 million to $8 million in the second quarter driven primarily by IT investments and general hiring to support growth.
We're investing to support our long-term market share goal of at least 40% of the growing colon cancer screening market.
We estimate there are 87 million average risk Americans between the ages of 15 and 85.
In 2030, that number is expected to grow to 97 million.
In 2030, there will also be 20 million average risk people between 45 and 49 years old, for a total available market of 117 million people assuming Cologuard's label expanded.
That equates to a $20 billion U.S. opportunity, and our goal is to capture at least 40%.
In order to support this goal, we're investing in our people, infrastructure and lab capacity.
Total first quarter CapEx was $52 million.
For the full year, we continue to expect CapEx of $175 million to $200 million.
First quarter cash use totaled $77 million.
We expect the majority of our cash use in 2019 to be CapEx-related, similar to last year.
We ended the quarter with cash and securities of $1.3 billion, including $236 million net raised in relation to the refinancing of outstanding convertible notes.
Turning to our guidance.
Based on our first quarter performance and our updated expectations for the rest of 2019, we're raising our full year revenue outlook to $725 million to $740 million from our prior range of $710 million to $730 million.
This assumes 1.52 million to 1.54 million completed Cologuard tests.
For the second quarter, we expect revenue of $178 million to $183 million and Cologuard volume of 372,000 to 382,000 completed tests.
I will now turn the call back to Kevin.
Kevin T. Conroy - Chairman of the Board, President & CEO
Thanks, Jeff.
The Exact Sciences team is focused on 3 priorities in 2019: powering our partnership with Pfizer, enhancing Cologuard and advancing our pipeline of blood-based cancer diagnostic tests.
Our sales and marketing teams are executing at a high level.
During the past year, they successfully implemented new selling strategies and techniques to continue to grow Cologuard.
Demand from new health care providers also remained strong with nearly 14,000 ordering their initial Cologuard test during the first quarter.
The team is collaborating effectively with Pfizer and embracing a shared commitment to grow Cologuard and screen more people.
We're seeing a positive impact from Pfizer's January launch of Cologuard through its women's health field force.
The number of OB/GYN providers ordering their initial Cologuard doubled in the first quarter.
More than 5,000 in total have ordered since launch.
There are more than 30,000 OB/GYNs in the U.S. and approximately 25% of their patients are 50 years and older, making them an important market segment to help screen more people with Cologuard.
The marketing team introduced new television ads in the first quarter to maintain the effectiveness of our national advertising campaign.
We continue to work closely with Pfizer's team to enhance creative messaging, optimize the mix of advertisements and effectively invest to raise Cologuard awareness.
Gastroenterologists are key influencers in colon cancer screening, and partnering with them will play an important role in achieving our long-term goal of capturing at least 40% of the colon cancer screening market.
We're hiring a GI sales team so we can reach them more frequently and expect them to be in the field in the third quarter.
We're also implementing a robust peer-to-peer program to educate primary care providers about the value of Cologuard.
This program will provide a new format for providers to learn about Cologuard's benefits from their peers.
As our sales and marketing efforts grow Cologuard demand, we're investing in our infrastructure to ensure we can efficiently support that growth.
Our lab expansion projects remain on schedule and within budget.
Necessary approvals are progressing to support a significant increase in total lab capacity by the end of this year.
We also expect to have Epic's electronic health record system implemented this year.
This will reinforce our IT infrastructure, help us scale cost effectively and enhance the Cologuard user experience for our employees and our customers.
Our second priority is enhancing Cologuard, to expand access to Cologuard and its total market potential to nearly 18 billion.
We recently submitted our application to the FDA for a label expansion to age 45.
Expanding Cologuard's FDA label to the nearly 19 million average risk Americans between ages 45 and 49 is an important opportunity.
More than 10% of the total years of life lost to colorectal cancer are due to a diagnosis between ages 45 and 49.
This exceeds the impact in every 5-year age group above age 70.
Since 1994, the incidence of colorectal cancer increased more than 50% in people younger than 55.
We believe Cologuard could help solve this problem.
Since the American Cancer Society updated its guidelines last May, several large insurance providers have lowered their coverage screening age to 45, including Anthem for federal employees, Aetna and CareFirst.
We're excited about this early progress and look forward to working with the agency to insure more Americans have access to an easy to use, noninvasive, accurate screening option.
We are pleased with initial data from new markers we're evaluating for Cologuard 2.0 in terms of both sensitivity and specificity.
These markers have the potential to increase Cologuard performance and further improve the overall health economic case for Cologuard.
We will provide updates as we validate these markers and work with the FDA on an approval pathway.
Our third priority is advancing our blood-based cancer diagnostics program.
The strong foundation we built for Cologuard and its commercial momentum position Cologuard to lead this field.
Through our long-term collaboration with Mayo Clinic, we have discovered biomarkers associated with 15 of the deadliest cancers.
We have identified markers for most of those cancers through our rigorous research and development process.
Once we have identified markers for a cancer in tissue, our team performs multiple studies to validate the best markers for that cancer.
Next month, we'll share several pieces of new early data at Digestive Disease Week.
This data are evidence of the strength of our partnership with Mayo Clinic and the power of our platform for early cancer detection.
In addition to our pipeline work, we will present real-world evidence supporting continued Cologuard use for providers and guideline groups at DDW.
One of the liquid biopsy tests we're working on in collaboration with Mayo Clinic is for liver cancer, a disease that kills 30,000 Americans and 600,000 people worldwide each year.
There are more than 3 million people who should be tested regularly in the U.S., and our goal is to provide a better option than the current standard of care, ultrasound, either with or without the alpha-fetoprotein test.
Early-stage cancer sensitivity for ultrasound alone is estimated to be 45% and combined with AFP, it is still less than 65% sensitive.
Patients fail to comply with recommended testing more than 2/3 of the time.
A more accurate and convenient test may unlock a large market opportunity, encourage more people to get tested.
We're enrolling a large case-control study to further validate and finalize development of our liver cancer test.
We've also begun evaluating potential sites to open a new lab for our future pipeline products.
We look forward to providing updates as we continue this work and refine the go-to-market strategy.
We're now happy to take your questions.
Operator
(Operator Instructions) And our first question comes from the line of Patrick Donnelly from Goldman Sachs.
Patrick B. Donnelly - Equity Analyst
Maybe one for Kevin or even Mark just on the Pfizer reps.
Now that we're a few months into this, can you just help us think about how those guys are ramping relative to the exact reps historically, whether it's on the utilization side or the new doc adds?
Obviously, the new doc adds of 14,000 this quarter was an impressive number.
So maybe just to help us think about how those guys are ramping against historic -- versus historical Exact guys?
Mark Stenhouse - President of Cologuard
Our guidance for Pfizer would be consistent to how we've guided the Exact Science representatives.
It takes 6 to 12 months for a representative of Cologuard to become effective on their response curve with doctors.
What we're most excited about is the opportunity to grow this business through the partnership.
Both the qualitative relationship in terms of the engagement between the field representatives, the marketing organization, the health system teams, we believe, is going to enable us to grow this business from the 4 to 40 share that we were guiding.
But it is encouraging to see the new doc adds, and it's encouraging to see all of the organic growth in the business as a result of the partnership.
Patrick B. Donnelly - Equity Analyst
Okay.
That's helpful.
And then just maybe on the new doc adds, you did 15,000 last quarter, another 14,000 this quarter.
The historic run rate for the past couple of years was around 10,000.
So is this kind of the new normal?
And then on top of that, what's the real driver?
I mean is it Pfizer?
Is it the 100 reps you added midyear last year?
Maybe just help us think about that run rate there.
Jeffrey T. Elliott - CFO
Sure.
The drivers are broad-based there, Patrick.
When you think of historically, we had seen -- a number we've worked out, typically about 90% of the new providers that ordered Cologuard were marketing converted.
So we're continuing to see strength in our marketing programs and their ability to drive new providers to Cologuard.
Our sales force continues to add more providers, and now the addition of the Pfizer team has been a very nice contributor.
So the drivers are broad-based.
As far as where this can go forward, our focus is on driving long-term sustainable growth for the company.
For us to achieve that, we want to capture as many of those providers as possible.
Today, there's still over 60% of the primary care providers out there have not ordered Cologuard.
So we want to capture as many of them as possible.
Can we sustain this level of pacing?
Well, historically, that growth had been 10,000 a quarter before Pfizer.
I hope that we could sustain that level or better at least near term.
I don't expect us to reach the 15,000 level which we did in the fourth quarter.
I don't expect that to be sustainable near term.
Operator
Our next question comes from the line of Brandon Couillard from Jefferies.
Brandon Couillard - Equity Analyst
Jeff, I didn't hear you speak to the compliance rate number in the first quarter.
Could you share that with us and kind of your expectations for the next few periods relative to, I think, what was an expected uplift in that metric?
Jeffrey T. Elliott - CFO
In Q1, the compliance rate was 65%.
That did tick up from 64% in the fourth quarter, and what we continue to expect for Q2 is 67%.
So the teams are making some nice progress there.
Long term, nothing's changed.
We think we can get that rate over 70% long term.
Brandon Couillard - Equity Analyst
Super.
Then a question for Mark.
When we spoke in January, I think you mentioned moving to a new sales CRM system.
Can you give us an update on that progress and then more specifically what you're doing around digital marketing efforts and some of the closed-loop marketing and sort of follow-up communications that I think you kind of expected to roll out to the team in terms of functionalities this year?
Mark Stenhouse - President of Cologuard
Yes.
So we're going to go on to Veeva or Salesforce.com platform as a company late this year.
So we've not migrated to that new platform system.
It will enable all the benefits that you've outlined: closed-loop marketing, better management of the field execution.
All that will be driven off iPad platform for the reps to engage their physicians, and the selling message as well is to engage them in follow-up.
The journey to get there though is not just sticking with the status quo.
We've kind of tailored our messaging to specific physician segments as a way to grow our ordering base of providers as well as deepen their penetration of use of the brand.
So we're evolving kind of the selling strategy as well as the technology platform in parallel.
It just takes time with the way of the different tech -- IT transformations that we're having at Exact Sciences to include the move to Epic, way to sequence to Veeva on-boarding appropriately behind the Epic platform change.
Operator
Our next question comes from the line of Brian Weinstein from William Blair.
Brian David Weinstein - Partner & Healthcare Analyst
Mark, I've been obsessed with these performance response curves and just wanted to ask you, are those still holding?
Can you give us some metrics around that?
Are you seeing it matter if it's an Exact rep or a Pfizer rep or a joint call that sort of influences those performance response curves at this point?
Mark Stenhouse - President of Cologuard
Brian, the response curves are fascinating to look at.
We look at weekly performance metrics of call activity.
And as you've indicated, we see that data in the shared targets and the independent targets between Pfizer and Exact.
The curves themselves are holding true, and those curves signal the more rep effort applied to an ordering physician.
You see greater consumption of our product.
So that fundamental is still there.
You also see where we have a shared target between Pfizer and Exact Sciences, deeper penetration in that cohort of doctors.
So that holds up the pieces because where they're sharing targets, there's also more activity.
So I think the entire story is still what it is: I think driving a lot of the value that we're seeing quarter-over-quarter.
Brian David Weinstein - Partner & Healthcare Analyst
Is that concept of 6 and 9 still -- does that still hold the calling on 6 times and 9 times as many order?
Does that still hold?
Mark Stenhouse - President of Cologuard
Yes, roughly that's the model that we're looking at internally.
Brian David Weinstein - Partner & Healthcare Analyst
Great.
And then, Jeff, I think you mentioned, or I don't know if it's Kevin that mentioned, the GI sales force.
Can you just tell us how big that is?
And is -- corollary to that, how does that influence your operating expense spend for the year?
And what do you expect the expense to be to total OpEx for the year?
Mark Stenhouse - President of Cologuard
Brian, why don't I take sizing and I'll give it back to Jeff for operating expense?
So the sizing of the sales force is 60 representatives plus management.
Over half that group has already been hired, all of the management and half the reps.
But the half that's been hired was an internal promotion for the very best of our frontline PMR representatives, the field sales force in primary care.
The other half will be externally hired with significant GI experience, and they'll be in the field in the third quarter.
Jeffrey T. Elliott - CFO
So for the second quarter, I guided to a sequential OpEx increase of $6 million to $8 million.
That assumes selling and marketing relatively flat sequentially with about 2/3 of the sequential growth from G&A and the rest from R&D.
If you look at selling and marketing for the year in total and compare it to the fourth quarter of last year, about 2/3 of the growth that we expect this year in selling and marketing is related to the Pfizer service fee.
About 1/3 is related to internal investments, primarily the GI sales force.
That will more likely hit the back half of the year as those reps come online.
Brian David Weinstein - Partner & Healthcare Analyst
Last question for me on data.
Kevin, I think you said that you have something at DDW.
Is there other -- are there other data sets from products that we should be expecting later this year?
Or is DDW sort of the main place that we'd see something on any of your products in the pipeline this year?
Kevin T. Conroy - Chairman of the Board, President & CEO
Well, we do have data on Cologuard 2.0 that is internal data presently, and we are looking for the right conference to present that data showing the performance of -- what the new markers, what Cologuard 2.0 looks like relative to Cologuard and we can talk about that more later.
Operator
Our next question comes from the line of Derik De Bruin from Bank of America Merrill Lynch.
Unidentified Analyst
This is [Ivy Wong] for Derik today.
We've heard a lot of noise at AACR in the past month on regional mixed market development from a lot of the smaller players.
We know that's part of the Cologuard 1.0, but just we'll appreciate any additional color around that.
And then any color on the Cologuard 2.0 biomarker that we just talked about?
Kevin T. Conroy - Chairman of the Board, President & CEO
Why don't we start with Cologuard 2.0?
We have seen data that's quite promising internally, and our goal with Cologuard 2.0 is to maintain the same level of sensitivity for detecting cancer, 92% and 98% Stage I. So when you're in a screening setting, you don't want to miss cancers, especially your early-stage cancers.
And then our primary goal thereafter is to improve the specificity and therefore lower the false positive rate.
We saw that with the Cologuard 2.0 markers in stool, and we had a head-to-head comparison in those samples with the current Cologuard tests.
So we're really pleased with the sufficient number of samples that gives us confidence to continue moving forward with the program and to sit down with the FDA, which we'll do yet this year, and then thereafter begin a prospective -- most likely, a prospective study.
In terms of any data from blood-based test, we don't comment on what others may do in terms of presenting data.
The thing that is important to us and to key opinion leaders, most importantly to key opinion leaders, is the ability to detect early-stage cancers with confidence at a high specificity.
If you're going to have a blood-based test, and most blood-based test that we've looked at don't have the ability to detect precancerous polyps, so by definition you have a test that detects cancer, remember that almost half of cancers in a screening population are found Stage I.
And so it is -- at a minimum, you really want to be pretty close to where the FIT test is, is at detecting 2 out of 3 cancers.
We haven't seen data like that in a prospective study from anybody, and that fit the data that you want to see.
Even then, that indicates that there's probably a biological barrier to detecting early-stage cancers.
And we think such a blood-based test would have to be priced appropriately, and it is not likely to displace the 2 leading tests, Cologuard and colonoscopy, as the preferred high-sensitivity ways to detect Stage I colon cancer.
Unidentified Analyst
Just a couple timing updates.
Congrats on submitting the FDA application for Cologuard 45.
Just wanted to see if we have any updates on the timing for approval.
And once approved, how long should we expect to get any traction on that?
Mark Stenhouse - President of Cologuard
So there's no change in guidance for the FDA approval because -- that we've given previously, which is first half of next year.
We don't want to speculate in terms of how the agency may come back to us with questions.
But obviously, we have confidence in our submission based on the strength of the evidence that was submitted and our conversations with the agency themselves.
You had a second question on the timing of review by the agency?
Unidentified Analyst
Yes, just how long we could get -- we should expect to -- for that to get traction?
And then...
Mark Stenhouse - President of Cologuard
Yes, okay.
So I think the traction question is really a by-product of coverage and reimbursement, and I think there's a couple things that we can signal here.
One is that the ACS mandate for coverage of the screening population, which is grounded in the underlying science, the epidemiology and incidence rise in this population, really inspired the submission and our charge to really screen this important age cohort and it is central to the idea of detecting cancer early.
And I would also say what we're saying is not only did the ACS decision influenced payers like Aetna and CareFirst and the Anthem FEP business that Kevin mentioned earlier, but even in our early discussions with our partners and our payer partners, we're seeing many that we believe will likely move in the direction similar to Aetna and others that will wait for USPSTF guidance.
So my view is that we will have a variable access market at the label's indication approval and that we'll see how that matures over time.
Operator
Our next question comes from the line of Doug Schenkel from Cowen.
Doug Schenkel - MD & Senior Research Analyst
Q1 test volume of 334,000 tests was 19,000 better than the midpoint of your guidance.
I'd be curious how much of this was new doctor additions versus order rates in terms of how those tracked versus your internal plan.
I guess really what I'm trying to get at is exactly that last point, I guess, which is what are the key drivers to the volume upside?
And what is really going much better than you expected when you issued guidance earlier this year?
Jeffrey T. Elliott - CFO
So this is Jeff.
I can start then maybe Mark could chime in at some of the broader drivers.
As far as the first quarter upside, most of the growth in the business comes from the increase in order rate from physicians.
So if you think back to historically, we had been adding about 10,000 new providers per quarter.
Q1 was a bit better at 14,000.
Now remember that's just in order.
Not all those orders result in a completed test during the quarter.
So by far, the biggest contributor in the quarter is an increase in order rate from physicians, and there the drivers are extremely broad base.
So maybe Mark could chime on some of those.
Mark Stenhouse - President of Cologuard
Yes, I think the things we've guided to historically, Doug, are still in play here.
There's the 100 rep adds that we put in the business in August of last year.
Obviously, the strength of the reach and frequency of the Pfizer sales force, the overlapping performance in the shared target in terms of the responder growth, the value of the TV, the value of broad market access and reimbursement, the value of health systems, all of those are maturing drivers of growth that really, I think, contributed to this quarter and last quarter's momentum.
Doug Schenkel - MD & Senior Research Analyst
Okay.
So that's a perfect setup for my second question, which is if we look back over the past 6 quarters, the number of completed orders per physician has increased or per practice has increased by an average of 0.6 sequentially, meaning, quarter-to-quarter.
This quarter it increased by 0.9 -- yes, 0.9.
And then I guess looking forward, as the Pfizer reps increase their physician detailing, as the new Exact reps you hired last year continue to gain efficiencies and as the practice prioritization tools put in place last year continue to improve and gain steam, would you think it's fair to expect that if all tracks to your internal plan, that the slope of improvement in orders per practice will continue to ramp over the next several quarters?
Jeffrey T. Elliott - CFO
Obviously, Doug, our goal is to keep driving that rate higher.
If you look today, we are only between 5% and 10% penetrated into the average providers office.
So there's a long ways to go.
The internal data we have on provider stickiness and provider adoption is incredibly attractive, so we're very optimistic about the long term.
We are making investments today to get to our long-term market share goal of at least 40%.
So we do expect that orders per provider number to continue to raise.
It won't always be a straight line though.
When you look at the guidance for the year, it does reflect our confidence in the business.
It also reflects some soberness when you think of the uncertainties for the remainder of the year.
For example, Mark talked about the new GI reps.
Well, we have to factor in a range of outcomes for the productivity of those GI reps.
In addition, we are making some significant IT upgrades this year.
So we have to allow for a range of outcomes and a range of impacts from those changes in the business.
Doug Schenkel - MD & Senior Research Analyst
So -- okay.
Another good setup for my last question.
Your Q2 guidance for volume and revenue suggests that you expect at least partial continuation of Q4 and Q1 trends when it comes to completed order growth sequentially and ostensibly by extension, the number of new ordering providers and the number of completed orders per practice.
That said, when I take your new full year guidance and back out Q1 results and your Q2 guidance, it seems to imply that you are expecting a moderation in the pace of new practice additions and/or growth in orders per practice.
And that's different from being cautious on the impact of the OB/GYN detailing.
It -- I didn't hear anything on the call that suggests a second half moderation in the pace of momentum is likely to occur.
Again, new advertising and the efficiencies associated with the Pfizer agreement would seemingly yield more gains and practice additions over time, and Pfizer should help with practice detailing frequency and by extension, order rates.
Am I missing something here, or you're just trying to be prudent early in the year?
Jeffrey T. Elliott - CFO
Well, you're correct, Doug.
It is early in the year.
We raised the full year guidance by more than the first quarter upside.
For the second quarter, what we baked in the guidance there is the highest reorder rates that we've ever seen and the second largest sequential step up in growth off of a very good first quarter.
So we're extremely confident in the business.
We do expect continued growth both near term and long term.
Again, 40% plus is what we're targeting long term.
In the second half of the year, what we've implied for the sequential growth is a pacing that's above the rate that we've historically seen pre the Pfizer relationship.
So we do expect continued strong growth.
It is early in the year.
Operator
And our next question comes from the line of Catherine Schulte from Baird.
Catherine Walden Ramsey Schulte - Senior Research Analyst
First, any thoughts on Medicare's recently announced Primary Care First program including colorectal cancer screening as one of its measures?
How much of a tailwind could this be for you guys?
Do you typically see higher order rates from providers that are in value-based models?
Mark Stenhouse - President of Cologuard
We're still evaluating the impact.
It's early.
So I think we'll be able to give you more guidance after we've had a little more time.
Catherine Walden Ramsey Schulte - Senior Research Analyst
Okay.
And then how does the class of reps hired last summer ramped relative to your expectations?
And then we'd love to get any go-to-market strategy color for the GI sales force and how that might differ from your traditional primary care reps.
Mark Stenhouse - President of Cologuard
So every new cohort of rep we add into the population continues to outperform its precedent, and even the original cohort continues to grow over time.
So yes, it's a good news story.
There's growth everywhere.
I think the condition's obviously that latter cohorts are better in terms of coverage and reimbursement, which allows for kind of incremental growth, and we're getting better at training and knowing better ways to activate our reps once they get in to the market.
Specific to GI, here's -- the fundamentals are clear.
We have 8,000 ordering doctors, but they've ordered very thinly in the GI community, but yet we know they influence their primary care network.
So the idea here is really twofold.
One is we have a pipeline that Kevin's acknowledged that has an opportunity for our GI sales force to gain efficiencies on those pipeline of assets when they come to market.
But for Cologuard specifically, the idea in go-to-market is to make sure that they cannot only educate the doctor clinically on the value of our product, but then use their partnership to then unlock their community of referring physicians.
Clearly, GIs are bias to colonoscopy, but they also recognize the value of a noninvasive test and they recognize the value of Cologuard as the best noninvasive test available.
And now that it has universal coverage, we see that there's a real partnership opportunity here that will enable us to grow this brand at 40% market share over time.
Catherine Walden Ramsey Schulte - Senior Research Analyst
Great.
And last one for me.
Now that you have Pfizer helping out on the health systems side, any potential for care gap programs, be it with those health systems or payers?
Mark Stenhouse - President of Cologuard
Yes, I think we just left a very productive collaboration meeting with Pfizer across our health systems team and theirs to continue to evolve our strategy.
The thing that I was most excited about is less about care gaps, but really about focusing on the fundamental strategy of putting in a quota for cancer screening pathway within the health system and then making sure that Cologuard sits appropriately within that care pathway.
And we're already seeing evidence of this partnership and the focus on these 2 core fundamentals to include electronic ordering, to include physician access, which are things that we've guided to historically.
Those 4 things, pathway, Cologuard's appropriate placement, electronic ordering and access to physicians, really unlocks value.
And that's one of the things we're seeing embedded in the revenue guide, and I think that will only mature over time.
The sales cycle is still long because you've got to move across a large matrix organization, but we definitely see that we focused on the right fundamentals.
Operator
Our next question comes from the line of Dan Brennan from UBS.
Daniel Gregory Brennan - Senior Equity Research Analyst of Healthcare Life Sciences
So the first one is on the test utilization, back to Doug's question.
I'm just wondering, maybe Mark or Jeff or Kevin for that matter, what are the reasons you hear why doctors amongst, let's say, 160,000 or so ordered at least once, why they might order once or twice and don't reorder?
And kind of what are the methods in place to overcome that pushback?
I mean we just finished the second survey that showed nearly 40% of docs still cite lack of insurance coverage or out-of-pocket expense as the hurdles.
So obviously you had that messaging last year, but now that time has lapsed, I'm just wondering why that's still such a hurdle.
Mark Stenhouse - President of Cologuard
I think there's 2 answers.
One is the one your survey acknowledged, which is once you have broad access and you have 300,000 potential ordering physicians, getting the message to that universe of doctors takes time.
And it takes repetitive effort to really stick the message in their mind space before it converts to actual ordering behavior.
I think the other real issue is you've got a market that's been anchored to colonoscopy for years, right?
And you will find some physicians that believe that any noninvasive test is an alternative test versus offering patients the choice at the offer -- at the age of 50 when they convert.
So I think it's really converting doctors to believe that Cologuard is a frontline screening option for all patients, and doctors get to that adoption cycle at different points in time.
If you look underneath that, what motivates them to move faster is more frequent rep contact.
The more rep contact we have between Pfizer and Exact Sciences does drive that behavior over time.
So it does signal where we need to place our reps, the frequency by which we need to place them in doctors, which should give you some sense of how we think about sizing of the sales force and how we then also applied the media TV effort that mirrors it.
Daniel Gregory Brennan - Senior Equity Research Analyst of Healthcare Life Sciences
Okay.
And then maybe on the retest opportunity, Jeff, maybe could you just talk through, and if you don't want to give us an exact number, but by our math, nearly 240,000 patients are eligible.
And if you'd kind of take out positives and assume some kind of move or a patient -- or excuse me, the outpatient's loss due to move or whatever else might be, it's still coming up, but probably north of a 150,000-patient opportunity.
So I'm just wondering kind of what you've assumed in your guidance for 2019, and any other color on how that retest opportunity is developing?
Jeffrey T. Elliott - CFO
We've assumed that we continue to make steady progress, which we have done.
We're not satisfied with the rate that we're at.
We've got a Tier 1 project team on this one.
And I'm confident that long term, we will do a better job at capturing more of these patients.
I think Mark could talk to some of the initiatives underway to capture them.
Mark Stenhouse - President of Cologuard
Yes, I mean, I think it's very clear that we've made some progress but not enough to address this.
So the way that you really anchor patients to reorder is to -- part of this is the early cohort had a variable experience.
We had modest coverage in terms of reimbursement.
We may have had a bill, right?
So getting that patient back to us requires different types of marketing initiatives, and we're really kind of testing.
And if it doesn't work, trashing and trying something different.
So there's a lot of test and control experimentation going on to try to find the right sequence of engagement with patients.
But I would say we still have a lot to learn here.
This is an area of opportunity for us, and I think we'll get better at this simply by going through that experimentation phase.
Daniel Gregory Brennan - Senior Equity Research Analyst of Healthcare Life Sciences
And maybe just one final one for Kevin.
Kevin, as you kind of look back at the way the Pfizer relationship has progressed, 2 quarters of live action under your belt, kind of can you just speak to anything that may have surprised you or anything that's either going better or maybe not as well as expected?
Kevin T. Conroy - Chairman of the Board, President & CEO
Dan, Pfizer is a tremendous partner with quality people who are committed to the same cause that we are.
So we're thrilled with the caliber of the team we're working with.
And it's early.
We still have a lot of work to do together, and so I think the best is yet to come there.

Our next question comes from the line of Puneet Souda from SVB Leerink.
Puneet Souda - MD of Life Science Tools, Diagnostics, and Senior Research Analyst
(technical difficulty)
these practices.
I was hoping to understand what's your sense of overlap now among the sales forces and sort of wanting to understand, are you still employing the same targeted strategy of select high-potential physicians?
Or has that broadened a bit?
Or what's the timing?
When do you think that can potentially broaden now that you have more reps?
Mark Stenhouse - President of Cologuard
So yes, the targeting strategy is biased based on previous ordering history, and Medicare affiliation is the kind of 2 by 2 grid that we use at Exact Sciences.
You have to remember that Pfizer has a portfolio of products.
Their targeting strategy is based on a range of products.
So there isn't exact overlap in the targeting methodologies nor will there be because Pfizer isn't selling Cologuard in a P2 or P3 position, again, against the portfolio.
So we have overlapping targets.
We have independent targets.
What we see is in the overlap targets, see greater traction and growth in the order rates.
I think we will evolve based on our understanding of responsiveness -- response curves that we've talked about over the past several calls.
We will use that data to inform our sales force sizing strategy at Exact and where we decide to take the size and scale of our frontline sales force going forward.
Puneet Souda - MD of Life Science Tools, Diagnostics, and Senior Research Analyst
Okay.
Great.
And this one is for Kevin maybe, if I could ask around DDW.
Is it safe to assume that the highlight there is going to be really around liver?
Or should we be actually looking for some of the markers, maybe not specifically around blood but maybe around Cologuard 2.0?
Kevin T. Conroy - Chairman of the Board, President & CEO
Two main things.
Number one, a number of abstracts are focused on Cologuard.
Wait until DDW to see what those abstracts are.
I think 5 or 6 altogether, and then also data around pancreatic cancer detection from blood, a sizable study in collaboration with the Mayo Clinic.
So those are the key things that you'll see Cologuard 2.0 will come at a later date.
Cologuard -- or colon cancer from blood, I'd like to restate what we've said in the past.
We think that we have a product that is best positioned to enter the market at some point.
It's still not a test that would displace Cologuard or cannibalize Cologuard in a meaningful way.
Eventually, we think that is something that we would want to bring to patients and physicians who refuse either colonoscopy or Cologuard.
And that data, we haven't decided the right time to present.
Operator
And our next question comes from the line of Mark Massaro from Canaccord Genuity.
Mark Anthony Massaro - Senior Analyst
Congrats on a good quarter.
My first question is not all Americans have a primary care physician.
And so there are some lab providers that do enable consumers to go online and request a physician to order a test.
Can you just speak to how -- or whether or not this is something that you're thinking about employing going forward?
Because theoretically, it could drive some additional utilization.
Mark Stenhouse - President of Cologuard
We agree that there is a disconnected patient-physician base that could be activated with consumer-initiated testing, being able to go online and activate with that ordering doctor a Cologuard.
This is something we are actively researching and exploring.
I mean I think you would likely see us pilot something within the back half of this year or early next year.
Mark Anthony Massaro - Senior Analyst
Okay.
Great.
And I know since working with Pfizer, I think it's my understanding that you've been able to go and network at a lower rate, say, per commercial.
So I guess my question is, is there an opportunity at some point to find an optimal level of advertising that's effective that can drive enhanced utilization while perhaps shrinking the dollar amount of the spend?
Mark Stenhouse - President of Cologuard
So we definitely have response curves like we have in the sales force for TV media investment.
That level of responsiveness and where we are in the curve guides the overall level of investment we need to make.
The shifting patterns of consumer consumption of network TV versus video on demand versus cable and the expense of each of those cohorts of TV consumption or media consumption drives ultimately our media buying plan.
We gain the efficiencies of Pfizer.
But frankly, some of our demographic target is consuming media in more expensive channels.
So we actually have to figure out the right level of investment in aggregate, and then we have to figure out where to place that investment in terms of where our consumers are actively watching TV.
And that is how we're going to guide the investment.
Whether the overall investment goes up, down or stays neutral, we don't fully know at this point in time.
But I definitely think it's an evolving strategy.
Mark Anthony Massaro - Senior Analyst
Great.
And then my last question on the liver test, can you give us a sense for the size of this case-control study, when you expect to potentially initiate a clinical trial?
And then can you speak to any regulatory pursuits?
Kevin T. Conroy - Chairman of the Board, President & CEO
We have not disclosed whether we will launch a liver test as a lab-developed test or as a FDA-cleared or approved test.
We certainly will have conversations with the agency and work with them.
In terms of the size of the case-control study, it's in -- in terms of the number of cancers, it's several hundred, and in terms of the number of controls, it's approximately in the thousand range.
And we don't plan to run a, at the present time, a prospective study.
Three months ago, that was the plan.
We now based on further conversations with key opinion leaders, we plan to launch either as an FDA-approved test or a lab-developed test with a large, what will be a fourth or maybe even a fifth case-control study.
That gives us confidence in the sensitivity and specificity.
Operator
And we do have one more question from Bruce Jackson from Benchmark Company.
Bruce David Jackson - Senior Healthcare Research Analyst
I was wondering if I could get the Medicare percentage of the test mix for this quarter.
And then do you have a forecast for the -- where you think you might end up by the end of the year?
Jeffrey T. Elliott - CFO
So in Q1, the Medicare volume mix was 50%.
That's down from 52% in the fourth quarter.
As far as where that goes, I would expect it over the course of this year to continue shifting away from Medicare and towards commercial.
Long term, I think they're both somewhere in the mid-40% range, both commercial and Medicare.
Keep in mind that outside of commercial and Medicare, there's some smaller components of this market, such as Medicaid, that's collectively at up to 5 or 10 points.
Operator
And our last question comes from the line of Per Ostlund from Craig-Hallum.
Per Erik Ostlund - Senior Research Analyst
Wanted to follow up on one of Mark's answers to Mark Massaro's question related to the television campaign.
So you went on the network TV kind of full-bore for the first time in Q4.
Do you hold network to a different bogey or a bar than you held cable?
Do you measure the ROI any differently?
Do you -- can you really delineate it from the -- from each other all that well?
Or I guess at a point, does it even matter?
Is media just media?
Mark Stenhouse - President of Cologuard
I mean I think the idea with media is to try to drive viewership to your asset, and you're trying to chase your demographic target where they're actually consuming media.
So our move to network and sports, NFL, which you saw us in the fourth quarter and you'll see us likely play in sports going forward because there's broad viewership there, is really a mix of optimizing our mix.
The way I think of it is you should look at our -- what we're trying to do is gain efficiencies in 2 different places.
We're gaining efficiencies through the Pfizer buy because they buy at a better aggregate rate, and we're learning from Pfizer and our own team where our demographic target's consuming media then optimizing that mix of investment by channel.
And overall, that should drive a better return on that investment.
Jeffrey T. Elliott - CFO
I would add, the ROI on TV is already very, very strong.
What Mark talked about is looking for ways to always improve the ROI.
So even as it stands today, the ROI is great.
We've seen payback numbers when you look at the amount of ad spend it takes to drive new physicians.
We've seen payback numbers that it takes perhaps fewer than 4 Cologuard's worth of gross profit to cover the payback on each new provider that orders the test, and that assumes that all of the TV spending goes towards new provider adoption, which we know that it does help drive incremental orders from existing providers.
So it's an incredibly good ROI.
Operator
And I'll now turn the call back over to Kevin Conroy for closing remarks.
Kevin T. Conroy - Chairman of the Board, President & CEO
Thank you for joining us today to review our first quarter results and the progress we made towards our 2019 priorities.
Our strong start in this year, the execution of our sales and marketing teams, the foundation we've built for future growth gives us confidence that Exact Sciences is uniquely positioned to become the leader in early cancer detection.
Thank you to the entire team at Exact Sciences for your hard work and continued commitment to our mission.
Thank you.
Operator
And this does conclude today's conference call.
You may now disconnect.
