Thanks, David, and good afternoon, everyone. Thank you for joining us. We had an exciting second quarter. You have heard me speak about individual patients at the beginning of these calls. Now less than nine months into the AlloSure launch, CareDx supports approximately 1% of all the U.S. living kidney transplant patients. Our strategy to bring high value diagnostic solutions to transplant patients is now in commercial execution mode and show strong financial performance in the quarter. This afternoon, I will provide an update on the recent achievement across our two key business drivers, transplant testing services and transplant lap products. Mike will then provide additional financial details on our second quarter performance and discuss our 2018 guidance. It's great to see the acceleration of our top line with total revenues growing 48% year-over-year to $17.8 million driven by a 66% year-over-year percent increase in testing services revenue to $14 million. Our second quarter adjusted EBITDA was a loss of $0.8 million and improvement from a loss of $3.2 million in the prior quarter. We are clearly seeing momentum in our business and remain on track to deliver positive adjusted EBITDA in the back half of 2018. AlloSure remains the biggest contributor to our robust growth with Medicare reimbursement in place and multiple peer reviewed publications supporting clinical and analytical validity, AlloSure is positioned for continued exceptional growth in the quarters and years ahead. Our laser sharp focus on better kidney transplant surveillance is being embraced by both patients and transplant centers. At the end of the second quarter, 76 centers had provided AlloSure results to their transplant patient since launch, which is higher than our initial internal projections. These 76 centers represent roughly half of the kidney transplant volume in the U.S. CareDx provided 2,300 patients results in the…

Thank you, Peter. Turning first the income statement, our second quarter 2018 testing revenue increased 66% year-over-year to 14.0 million. Our 2018 second quarter testing revenue includes our show volume of 2,300 tests, a 7% AlloMap volume increased to 4,132 tests and the January 1st increase in the AlloMap Medicare reimbursement rate from 2,840 and 3,240. We continue to be very pleased with the revenue and the momentum of AlloSure following the launch with test trajectory ahead of our initial expectations. Our second quarter product revenue increased 5% year-over-year to 3.6 million, and as such total revenue in the second quarter of 2018 with 17.8 million representing the 48% increase compared to the prior year 12 million. For second quarter of 2018, net loss was 14.1 million, compared to a net loss of 4.0 million in the same period of 2017. Our net loss per share was $0.40 for the quarter compared to $0.19 in the second quarter of 2017. The second quarter 2018, our non- GAAP net loss was 1.3 million, compared to a non-GAAP net loss of 3.6 million in the same period of 2017. Our non-GAAP net loss per share in the second quarter of 2018 was $0.04 compared to $0.17 in the same period of 2017. Starting this quarter, we are disclosing our adjusted EBITDA. We define adjusted EBITDA as non-GAAP net loss before interest, tax, depreciation, amortization, other expense and net loss attributable to non-controlling interest. For the second quarter of 2018, adjusted EBITDA was a loss of $0.8 million, compared to a loss of $2.1 million in the second quarter of 2017. Net cash used in operating activities in the second quarter 2018 was $1.9 million which was in line with our expectations and our cash and cash equivalents at June 30, 2018 was $16.2 million. Turning to guidance, we are increasing our 2018 revenue expectations to reflect the growth of AlloSure and now anticipate $68 million to $70 million for the year. We remain focused on driving the Company towards profitability and giving our expectations for a ramp in AlloSure contribution 2018 progresses. The positive Medicare price increase for AlloMap and the growth of our product revenues from Olerup QTYPE and our Illumina partnership, we continue to anticipate reaching adjusted EBITDA profitability during the second half of 2018. With that I'll open the call for questions

Thank you. We will now be conducting a question-and-answer session. [Operator Instructions] Our first question today is coming from Bill Quirk from Piper Jaffray. Your line is now live.

So couple of questions for me, and I guess the first one here you alluded to in your prepared comments. Can you give us a little additional breakdown for AlloSure test between those who have received a kidney transplant this year versus previous years? I think we've been pleasantly surprised at the interest kind of beyond year one but just curious about some additional color here specifically for 2Q?

Absolutely, Bill, and we continue to see a number of patients actually entering our AlloSure protocol beyond the one year. So with K-OAR coming on stream, and I have reported that there are 237 patients probably coming through the K-OAR standing order process, there's actually a substantial amount of patience in the outer years. We'll probably see that in the coming quarters a little bit skewed to the earlier transplant patients because of the K-OAR study. But right now, we continue to see very strong demand also in patients that are in year 2, 3 or even year 4 out in, after transplantation.

Okay great. And then on AlloMap, really nice to see that bounce back, certainly ahead of our expectations, Peter, you alluded to HeartCare being launched and can you speak a little bit to what sort of impact that may have had for the AlloMap volumes? Or do you think it's simply too early, any sort of impact is on the come here and that this is simply AlloMap volumes bouncing back from the inclement weather in the first quarter?

I think Bill, thanks for the question. I think we continue to see mid single-digit volume growth on AlloMap that we have been portraying. I think it's too early to really see a lot of impact on HeartCare. It is really only launched as a concept. There are not many HeartCare without provided yet. We'll believe that we'll provide HeartCare primarily through our sure registry that we will be launching in the second half of this year. So it's a little bit too early to say that think of it as a continued penetration mid-single digit volume growth as what we're aiming here.

Okay fair point. And then just two more for me one if I longer one quick one. Given the competitive announcement that came about six weeks ago. Can you just talk about I guess some of the response from your current users? Certainly that doesn't to have you had any impact on center growth or let's to be fair it came at the end of 2Q?

Yes I know same Bill here. It's very very early. I think we haven't heard actually a lot in the marketplace. I'm doing my tours and we have obviously the ear on the ground with a very vast presence in all these investments. And we don't hear anything in off the spent and success then apart here from the local UCSF center in -- 10 centers across the country. I think it's really early in this process. So no, nothing we hear from the field.

Okay. Got it. And then Mike just real quick one for you given the approaching profitability, just remind us what the additional diluted share count add is?

Yes Bill, what I'll standing -- is $36 million fully diluted including options and warrants it's $43 million.

Thank you. [Operator Instructions] Our next question is coming from Per Ostlund from Craig-Hallum Capital. Your line is now live.

Thanks. Good afternoon guys and I will echo Bill's congratulations as well, very solid quarter. Would like to get a literally this is early, but would love to get some early feedback on the protocol inherence of the standing order patients. I know that as we're thinking about modeling it certainly nice to have that standing order patient count continuing to rise like it is and give us that visibility. Are those patients that hearing to the protocol as well as you would hope and related to that, what sorts of programs are being put in place, whether it's by CareDx itself or by the clinicians to help drive that adherence?

Excellent question, Per. And I gave you the number to that we use our internal yardstick at 75% adherence. We do see adherence to the protocol in that range on our KOR study. And that gives us an indication that probably KOR will be even stronger on adherence than the regulation population. So probably adherence in the regulation population will be somewhere between 50% and 75% I would guess. What always the case in these protocols that initially adherence is actually higher in the first year for example than adherence in the second and the third year. So you're absolutely right that asking about what is our expectation on adherence, knowing that we have put in place patient care managers. We have a group now which is a sophisticated call center that actually makes sure that these patients to show up for that second and the third and the fourth and the subsequent AlloSure blood draw. And we think that this is a very important given that these patients are on an AlloSure protocol for three years, we need to have a model in place in order to bring them back and make sure that they get their AlloSure on time and have the test results that delivered right back to the center. So, adherence is going to be a core theme for us going forward to establish our flywheel concept.

Maybe just to follow-up on that. Are their learnings and admittedly AlloSure is the newer test on the block for you but are there learnings from driving that early adherence of the standing order patients that you can turn around and actually apply on the AlloMap side?

Yes, absolutely. And I think, we talked numerous times that actually on the heart program. We see that every heart program in the United States is using AlloMap slightly differently based on that biopsy protocol. So with AlloSure, we really turned the corner and said, let’s establish a basic AlloSure routine testing schedule, the arts protocol and make it the mainstay. And I think we’ve been very successful in making that the mainstay, especially to our to K-OAR registry study that you can only enroll patients when you follow this ARTS schedule. So this is a sea change that we bring to the field of transplantation, where we now have a standard protocol for probably 35, minimum 35 centers in the country that follow the K-OAR study.

The AlloSure volume number in the quarter, frankly kind of blew me away. I’m curious, were you -- would you say you were tracking to that kind of a quarter all along? Or did you get inflection, a positive inflection out of the Transplant Congress? And I guess just kind of on that point, I’d love to hear the feedback that you’ve gotten in the days and weeks subsequent to the Transplant Congress and how that met your expectations, because obviously was a very high profile event for CareDx?

Per, thank you very much. And I was a little bit concerned when you started the call with a solid quarter. And now I think you put that value into perspective. No, I think the ATC, the ATC symposium. We always knew that this is the highlight of the year and I think the team has nailed it. So this was at the end of the quarter, and we have seen tremendous interest and so in terms of your earlier questions, are we tracking to our expectations, I think you see that we have increased guidance we feel comfortable with our new guidance. So yes, we’re continuously executing extremely well and the ATC symposium has really been highlight and we executed very well on that.

Excellent. One last question and if you address this in your prepare remarks Peter, I apologize. But granted again it’s still early. But do you have anything you can share from a reimbursement experience standpoint today on AlloSure? Is it patient mix standpoint? How many came through Medicare? Or is it being reimbursement the level you expected?

Well, I think that’s a good question for Mike to answer.

Yes, the reimbursement is going as we expected. We have, we’re getting paid efficiently by Medicare. We’ve always said that the Medicare reimbursement would be covered 70% to 80% of the volume. Actually what we’re seeing is something like 75% reimbursement on our show, which is driving the revenue for the quarter.

Thank you. We have reached the end of our question-and-answer session. I’d like to turn the floor back over to management for any further or closing comments.

Well, thank you very much for joining the call. We look forward to updating everyone as you continue to commercialize AlloSure, grow AlloMap, and our transplant product business and progress towards profitability. Thank you very much for joining us today. Thank you

Thank you. That does conclude today's teleconference. You may disconnect your line at this time and have a wonderful day. We thank you for your participation today.
