James A. Schoeneck -- Interim Chief Executive Officer

Thank you, Mike, and thank you all for joining us today. During today's call, I will give you an overview of our third quarter results and recent accomplishments. Dr. Peony Yu will then give a review of the roxadustat data from the American Society of Nephrology meeting, which just wrapped up yesterday. Following that, Chris Chung will update you on our trying China efforts. Dr. Elias Kouchakji will give us pamrevlumab update and Pat Cotroneo will discuss our financials. Then I'll provide some closing comments and open the call to questions.

First, I want to take a moment to acknowledge with a great sense of loss, the recent and unexpected passing of FibroGen's Founder and long-term Chairman and CEO, Tom Neff. Tom was a man of vision, determination and leadership and was deeply committed to innovation. We at FibroGen are deeply indebted to him. Tom founded FibroGen in 1993 with the vision of creating fibrosis at a time when there was no hope for the disease category. He led the company for over 25 years and established a culture and a team driven to support his vision motivated by its commitment to improve the lives of those suffering from conditions with no satisfactory therapeutic options. In founding FibroGen, Tom assembled global scientific leaders in areas critical to the understanding of fibrosis and the fibrotic disease mechanism, ultimately, providing the basis for pamrevlumab and through the exploration of prolyl hydroxylase enzyme activity, the basis for roxadustat. Tom was intimately involved in the discovery and development of roxadustat and pamrevlumab and positioned the company for great success, given the breadth of the applications for both compounds. His contribution as a pioneer in the biotechnology industry will be measured by the lives that he has and will continue to touch, as FibroGen continues to develop medicines for unmet medical needs. The FibroGen Board and management team are committed to fulfill and build upon Tom's vision.

As you all saw, last month, the 2019 Nobel Prize in Physiology or Medicine was awarded to three physician scientists for their research in how cells sense oxygen and how they function in low oxygen conditions or hypoxia. The collective contributions of Dr. Bill Kaelin of the Dana-Farber Cancer Institute. Sir Peter Radcliffe, of the University of Oxford and Dr. Gregg Semenza of John Hopkins University School of Medicine identified the pathway by which cells detect oxygen respond to hypoxia. This seminal science has paved the way for promising new strategies to fight anemia, cancer and many other diseases.

FibroGen is fortunate to work closely with Bill Kaelin, our collaborator and member of the company's scientific advisory board for nearly two decades. Today, roxadustat is the first medication in the world which applies this groundbreaking science. As Dr. Bob Provenzano stated at the American Society of Nephrology last week, this is a great example of cutting edge science moving from bench to bedside. roxadustat is already approved in China for the treatment of anemia associated with chronic kidney disease and in Japan for CKD patients on dialysis. We are also currently preparing regulatory submissions for the U.S. and Europe.

Last week, during the American Society of Nephrology Kidney Week 2019, FibroGen and our partners Astellas and AstraZeneca presented roxadustat data from our Phase III program as well as pool cardiovascular safety and efficacy results. The pooled data kicked off ASN's high impact clinical trial session with a packed room of almost 2000 people. [Indecipherable] called it the largest crowd from anemia presentation in well over a decade.

This set of global studies covered the spectrum of chronic kidney disease, anemia and is believed to be the largest and most comprehensive study population ever reported with over 8,000 patients. Details of the data presented can be found on our website and in our press release from last Friday. Our studies assessed cardiovascular safety in dialysis and non-dialysis dependent patients gives the endpoints of major adverse cardiovascular events, known as MACE and MACE+, which adds hospitalization due to unstable angina in congestive heart failure.

The pooled results show that roxadustat's cardiovascular safety was comparable to placebo in non-dialysis dependent patients and in dialysis dependent patients roxadustat did not increase the risk of MACE and reduced the risk of MACE+ compared to epoetin alfa, the leading product currently used to treat this population. Finally, in the subgroup of dialysis patients who recently started dialysis, referred to as incident dialysis patients, roxadustat reduced MACE by 30% and MACE+ by 34% compared to epoetin alfa. roxadustat achieved the primary hemoglobin efficacy endpoints in all of these groups.

Of note, roxadustat was shown to raise hemoglobin levels regardless of iron status at baseline in patients who required no supplementary IV iron and in patients with inflammation, the group that is difficult to treat with current therapies. Having an oral product with this safety and efficacy profile can offer patients with anemia of chronic kidney disease and their doctors, a treatment unlike anything currently on the market in the U.S. or Europe.

Let me briefly mention a few other highlights from the quarter. We initiated our Phase III pamrevlumab program, enrolling the first patients in our idiopathic pulmonary fibrosis or IPF trial as well as our study in locally advanced pancreatic cancer. Our Phase II IPF trial was published in the Lancet Respiratory Medicine Journal and in the accompanying editorial Professor Athol Wells at the World Royal Brompton Hospital stated. In conclusion, it's difficult to imagine more encouraging Phase II results of a novel drug for IPF. In China, we booked our first roxadustat product revenue anywhere in the world and we continue to prepare for the full market launch with our 50-50 partner, AstraZeneca. In September, FibroGen and roxadustat won the 2019 Dushu Lake Prize for innovative drug with the highest clinical value in China. I think you'll agree with me. It's been a very, very accomplished quarter.

Now, I'll turn it over to Peony, who will give you a more in-depth discussion of roxadustat and the data from the ASN meeting.

Peony Yu -- Chief Medical Officer

Thank you, Jim. Last week FibroGen and our partners presented roxadustat Phase III results at the Annual American Society of Nephrology meeting, which included over 13,000 kidney professionals. As the nephrologists share our excitement of a potential gamechanger in anemia therapy based on strong scientific foundation. Today, I would like to review the highlights.

The pool analysis included the data from six Phase III trials including over 8,000 patients and encompass over 13,000 patient exposure years. Our studies evaluate the three patient populations; non-dialysis dependent, dialysis dependent and incident dialysis, which is a subgroup of patients recently started dialysis within four months of study's participation. We reported our result of the following safety endpoints. Major adverse cardiovascular events of MACE standpoint consist of death due to all causes, nonfatal myocardial infarction and nonfatal stroke. MACE+ consists of the three MACE events plus hospitalization due to heart failure or unstable angina. All-cause mortality is simply of that due to any cost.

To maintain objectivity and consistency, the events in these cardiovascular endpoints were adjudicated by independent adjudicators blinded to treatment assignment. The time-to-event analysis are conducted based on pooling strategy and analytical approaches agreed with the FDA and the time to MACE is the primary safety endpoint in the U.S. supported by results of MACE+, which is recognized as an important endpoint in the nephrology community.

In non-dialysis, where roxadustat was compared to placebo which is the gold standard in safety assessment, roxadustat was comparable to placebo in MACE and MACE+ risk using a commonly applied non-inferiority margin of 1.3. In dialysis patients, roxadustat reduced the risk of MACE+ by 14% compared to epoetin alfa and had no increased risk of MACE compared to epoetin using a commonly applied NI margin of 1.3. In incident dialysis, roxadustat had a 30% lower risk of MACE and a 34% lower risk of MACE+ than epo.

Let's discuss the rest of the efficacy and safety results starting with non-dialysis. 4270 plus CKD patients were enrolled into the three Phase III non-dialysis studies compelling roxadustat to placebo, ESA studies will include a CKD Stage 3, 4 and 5 patients. Of whom 42%, were CKD Stage 5. Their anemia tends to be more severe with a more advanced chronic kidney disease and they have been generally excluded from prior large CKD anemia studies of ESAs.

Similarly, we include a patient with a range of iron spores, with 40% of study patients non-iron replete at baseline and thus they were ineligible for ESA treatments based on the current ESA label. roxadustat met the primary efficacy endpoint of new change from baseline to average hemoglobin over weeks 28 to 52 in which, I'm sorry, in each of the three individual Phase III studies and in the pool analysis in which roxadustat was superior to placebo, regardless of CKD severity, regardless of severity of anemia at baseline and regardless of iron-repletion status. roxadustat's efficacy is accompanied by an 81% risk reduction in use of rescue treatment which includes IV iron, ESA and transfusion and a 74% reduction in the risk of red blood cell transfusion with p-value of 0.001 -- p-value less than. Importantly, in comparison to placebo, roxadustat patients also show a slower decline in EGFR, which is a measure of kidney function in patients with baseline EGFR of 15 or higher during the first year of treatment. The one-year decline in EGFR in Rockford patients was 2.8 which is significantly less than the decline in placebo patient of 4.4 with the treatment difference of 1.6 and p-value has been zero in it. This represents a 38% reduction in EGFR decline relative to placebo.

Turning to cardiovascular safety. In the CKD non-dialysis pool based on ITT analysis, roxadustat was comparable to placebo. For reference, here are the hazard ratios, MACE hazard ratio of 1.08 with 95% confidence interval 0.94 and 1.24, MACE+ hazard ratio of 1.04 with confidence interval of 0.91 and 1.18, all-cause mortality hazard ratio of 1.06 with confidence interval of 0.91 and 1.23. We have received questions on the individual components of cardiovascular composite endpoint in non-dialysis with the most interest in stroke. Well, this is most likely because of the treat study on Darbepoetin that resulted in the ESA labor restriction and its use in non-dialysis and dialysis patients.

I want to be clear from the outset. We believe the data from the individual components of MACE and MACE+ in the roxadustat program are consistent with the results in the overall analysis. Stated another way, we believe the results in the individual components are comparable to placebo in non-dialysis. This is also true for the dialysis pool. Before we delve into the details, I want to remind you that the roxadustat non-dialysis program was power for assessing the MACE composite endpoint and not the individual components. To give a sense of magnitude, in the roxadustat program, stroke represents only 10% of the MACE events in the non-dialysis pool and the incidence of rate in roxadustat is comparable to placebo, which is 1.2 per 100 patient years in roxadustat versus 1.1 in placebo arm, hazard ratio of 1.22 with 95% confidence interval of 0.80 and 1.86.

As a reminder, in the treat study, the incidence rate of stroke in Darbepoetin was twice that of placebo with hazard ratio of 1.92 and 95% confidence interval of 1.38 and 2.18. The rest of the MACE+ components in our non-dialysis pool is as follows; all-cause mortality hazard ratio of 1.06 confidence interval of 0.91 and 1.23 which we stated earlier. MI hazard ratio of 1.28 confidence interval of 0.9 and 1.84 and stable angina requiring hospitalization with hazard ratio of 0.49 and confidence interval of 0.19 and 1.27.

Finally, congestive heart failure requiring hospitalization which is important in CKD patients has hazard ratio of 0.89, confidence interval of 0.72 and 1.12. Based on the composite endpoints of time to MACE, MACE+, all-cause mortality and the individual components. The overall cardiovascular safety of roxadustat is comparable to placebo.

The dialysis dependent patient pool consists of 3,880 patients who were randomized one to one to receive roxadustat epoetin alfa in three dialysis Phase III studies. The primary efficacy endpoint of mean change in hemoglobin from baseline to week 28 to 52 was met in each individual study and each individual study and in the pool analysis. roxadustat achieved higher hemoglobin level than active comparator of epoetin alfa. This result was seen in patients with or without inflammation as measured by CRP with similar roxadustat both requirement regardless of inflammation status. What roxadustat treated patients receiving less IV iron than epo patients, while transparent saturation or TSAT, a measure of iron store in the body were comparable between the two treatment arms. In addition, when compared with epo, roxadustat treated patients had a lower ReproCELL transfusion risk than epo treated patient, hazard ratio of 0.82 p-value up 0.46. A combination of findings above reflects the benefits of coordinated erythropoiesis with roxadustat as treatment, we saw that more efficient iron utilization, lower transfusion requirement and can potentially overcome ESA hyporesponsiveness.

Turning to cardiovascular endpoint analysis after dialysis pool. In MACE and in all-cause mortality, roxadustat had no increased risk relative to epo. In MACE+, roxadustat had a 14% reduction iron risk compared to epo. I would like to point out the incidence rate of each of the individual MACE+ components. In dialysis are numerically lower in roxadustat than epo.

Finally, let's talk about the exciting patient population. Incident dialysis, which is a prespecified subgroup of the dialysis dependent pool. Here we study 1,526 new dialysis patients who commence treatment within four months before study participation and were treated up to three years with an average treatment duration of 1.5 year. In the Incident dialysis pool, in comparison to epoetin alfa, roxadustat treatment resulted in a 30% reduction in the risk of MACE and a 34% reduction in the risk of MACE+ with the trend for lower risk of death. These results suggests potential long-term safety benefits in selecting roxadustat when initiating anemia therapy in dialysis patients.

To evaluate the merits of roxadustat, it is important to put together an overall picture taking into account efficacy and safety and ask if this drug has the potential to improve anemia treatment in CKD patients. Our answer is yes. In non-dialysis, our Phase III program show roxadustat treatment corrected anemia effectively regardless of iron repletion and reduced need of rescue use of blood transfusion, while [Indecipherable] slowing down the decline in kidney function in patients with EGFR greater than [Indecipherable] while MACE, MACE+ and all-cause mortality risk were comparable to placebo, the gold standard. Because of the safety related treatment restriction of ESA coupled with the iron repletion requirement and the inconvenience or parenteral administration requirement currently there is little use of ESA in non-dialysis patients as U.S. RDS reported that only 15% of patients entering dialysis had received prior ESA treatment.

If approved, roxadustat could deliver the therapeutic benefits with the convenience of a pill unlike, ESA which requires frequent injections at the doctor's office. In addition to the favorable efficacy and safety characteristics, the convenient dosing of oral medication and removal of the financial and time burden from physicians need to stock and inject the medicine, we believe roxadustat has the potential to improve treatment access and patient compliance. Therefore, we believe we have an unprecedented opportunity to expand anemia therapy to the millions of non-dialysis patients whose anemia go and addressed.

In dialysis, currently the decision on the choice of anemia agent is generally made at the early periods of dialysis treatment. With a 30% reduction in MACE risk and a 34% reduction in MACE+ risk compared with epoetin alfa in incident dialysis patients, we believe roxadustat could be viewed as a safer option for patients initiating chronic dialysis, while benefiting from the robust efficacy in patients with or without inflammation with less IV iron use and lower transfusion rate compared to epo in the dialysis patients.

We are privileged to have an opportunity to potentially introduce a new standard for anemia therapy for CKD patients with roxadustat. A first-in-class agent based on Nobel winning Science. We believe these compelling efficacy results with demonstration of clinical benefit, a company by the above safety results could serve a strong basis for marketing approval in both the U.S., Europe and other countries in the world.

Working with our partner, AstraZeneca, we have made a substantial progress in preparing NDA for CKD anemia in patients on dialysis and in patients not on dialysis. We plan to submit the NDA for both indications before year-end. We are working closely with Astellas. Our European partner and expect to file the MAA for both indications in the first quarter of 2020.

Encouraged by the safety and efficacy results in CKD, we continue to expand treatment of anemia of other etiologies. In MDS, we have two ongoing clinical studies, a Phase III U.S. global study in transfusion dependent MDS patients and a Phase II/III study in non-transfusion dependent MDS patients in China. From Phase III global study results of the open-label leading portion, demonstrating roxadustat efficacy in MDS patients will be presented in an oral session of the upcoming American Society of Hematology meeting in Orlando next month.

We have also started a Phase II U.S. study of roxadustat for treating chemotherapy induced anemia, which we believe to have much opportunity to address the unmet need of a large unmet need of a large patient population. Our founding CEO led pioneering HIF PHI for anemia therapy. We are committed to carry on Tom Neff legacy to develop innovative medicines to improve patient care.

I now like to turn the call over to Chris Chung.

Chris Chung -- Senior Vice President of China Operations and Managing Director

Thanks, Peony. It has been an eventful quarter for us in China, publication of data from the two China only Phase III studies in the New England Journal of Medicine was a landmark event which was celebrated in China with much enthusiasm. The Chinese Nephrology Community envisioned itself as leading the way internationally in the adoption of a transformative new paradigm for the treatment of anemia in CKD. With the expansion of the China label to include non-dialysis, our partnership with AstraZeneca is serving us well. We are able to leverage the significant commercialization capability and launch experience of what is now the largest multinational pharma in China with coverage at over 6,000 hospitals that represent the vast majority of the potential market for roxadustat.

FibroGen in China has responsibility for medical affairs and we too have expanded our key opinion leader coverage and evidence generation activities over last few years from the original 30 Phase III clinical trial sites to now over 300 leading hospitals and counting. As a joint team, we continue to advance our efforts in market development, distribution, reimbursement and gaining listings in hospitals. China as the first launch market for roxadustat has given us some very encouraging early signals about prescriber and patient receptivity indicators, which are helping us calibrate the scale and scope of our ambitions for the market.

Looking at the different segments of the potential patient universe. In dialysis the installed base of over 600,000 patients is now the single -- the largest single country dialysis population of the world exceeding that of the United States. This is a substitution market for roxadustat. Treatment of anemia is well established, but only one-fifth of patients are treated to the target hemoglobin of 11. There continues to be double-digit growth in dialysis. After accounting for death, nearly 100,000 new patients come on to dialysis each year. They represent new candidates for roxadustat and many have no prior ESA experience.

Within dialysis, it's approximately 100,000 patients or 14% who are treated on peritoneal dialysis PD instead of hemodialysis HD. We believe the segment is particularly well suited for an oral therapeutic like roxadustat because patients receive PD treatment at home.

Finally, the non-dialysis segment is even bigger in patient count, but ESA use is much less established. We believe, as an oral therapy, roxadustat has the opportunity to greatly expand the addressable market.

We expect to know by the end of 2019 of roxadustat will be included in the updated National reimbursement drug list or NRDL. Inclusion would be an important inflection point for the business as it would greatly increase patient affordability, accelerate hospital listings and expand overall market adoption. This remains a stretch goal as historically the NRDL deal cycles were further part in time and drugs on the market for few years before inclusion. In the event roxadustat is not admitted in this round, reimbursement would be a top priority for us in 2020. We look forward to keeping you updated on the excited market opportunity in front of us in China.

With this, I will turn it over to Elias to describe these developments in pamrevlumab.

Elias Kouchakji -- Senior Vice President, Clinical Development, Drug Safety, and Pharmacovigilance

Thank you, Chris, and good afternoon. I'd like to start with some introduction of pamrevlumab. It is the first in class fully human monoclonal antibody that inhibit the activity of connective tissue growth factors, also known as CTGF. It's a critical mediators' of the progression of fibrosis and fibro prerogative diseases.

pamrevlumab is currently in Phase III clinical development for the treatment of both idiopathic pulmonary fibrosis, IPF and unresectable locally advanced pancreatic cancer also known as LAPC. pamrevlumab it's in the Phase II for the treatment of Duchenne Muscular Dystrophy and non-ambulatory patients. These diseases share a commonality of fibrosis involvement and each represent an area of significance end medical need in which these patients face a dia-prognosis.

I would like to start with an update on IPF. In July, we dosed the first patient in the Zephyrus Phase III clinical study of pamrevlumab in patient with IPF. We continue to activate additional site in this study and engage with our investigators to enroll patients. We are redoubling our efforts in improving our processes to bring sites online and expect an acceleration over the next few months. Our focus now is to activate sites with the expectation that the enrollment will accelerate in the year of 2020. In September, as Jim mentioned, we announced the Lancet Respiratory Medicine publication of positive result from the company's Phase II clinical study in IPF, showing both significant improvement in the primary efficacy endpoint of RBC change from baseline and reduction in disease progression in quantitative lung fibrosis as measured by HRCT also known High Resolution CT Scan.

This paper was well received by the medical community at the 2019 European Respiratory Society International Congress. We are very appreciative and encouraged by this reception. In this publication, the authors reported that pamrevlumab demonstrated the potential for stabilization of disease and, for the first time in human studies, the potential of reversal of lung fibrosis in some patients. I'd like to remind everyone that pamrevlumab has received orphan drug and fast-track designation from the FDA for the treatment of IPF.

Moving to LAPC, our Phase II results showed encouraging clinical evidence of potential of pamrevlumab plus chemotherapy to transform unresectable LAPC patient into patients who are eligible for surgical resection. We recently announced that the first patient was dosed in LAPC, our pivotal Phase III randomized double-blind placebo-controlled study, evaluating pamrevlumab as a neoadjuvant therapy for unresectable LAPC patients. This study will enroll 260 patient approximately to receive chemotherapy of gemcitabine and nab-paclitaxel who will be randomized to either pamrevlumab or placebo.

As you may know, this is very sick patient with limited options. But the primary endpoint of overall survival at the end of the treatment period. We will be evaluating the rate of resection as a surrogate endpoint for a potential accelerated approval. Similar to IPF, pamrevlumab have received both orphan drug and fast-track designation from the FDA for the treatment of this disease.

Turning to Duchenne Muscular Dystrophy, we will meet with the FDA this quarter to discuss the design of our pivotal Phase III program in DMD. We look forward to updating you in the future as this program advances. Also, we plan in the near future to publish additional data from patients who have completed one year of treatment in our Phase II study. pamrevlumab has received orphan drug designation from the FDA for this treatment of DMD. In clinical study, in multiple indications, pamrevlumab has consistently shown positive efficacy results as the [Indecipherable] good safety and tolerability profile. We are pleased to be progressing with the Phase III studies. To fulfill the vision of our late CEO, Tom Neff whose goal in funding FibroGen was to treat fibrotic diseases. We look forward to updating you on the progress of the pamrevlumab program in the future.

I will turn now the call to our CFO, Pat Cotroneo for the financial update. Pat?

Pat Cotroneo -- Chief Financial Officer

Thank you, Elias. As announced today, total revenue for the quarter ended September 30, 2019 was $33.2 million as compared to $29 million for the third quarter of 2018. For the same period, operating costs and expenses were $86 million and net loss was $49.4 million or $0.57 per basic and diluted share as compared to operating costs and expenses of $71.8 million and the net loss of $42.6 million or $0.50 per basic and diluted share for the third quarter last year. Included in revenue for the quarter ended September 30, 2019, our first commercial sales of roxadustat drug product in China, the related net product revenue was $600,000 for the quarter.

Also included in operating costs and expenses for the quarter ended September 30, 2019 was an aggregate non-cash portion totaling $19.6 million of which $14.8 million was a result of stock-based compensation expense as compared to an aggregate noncash portion of $16 million, of which $14.3 million was a result of stock-based compensation expense for the same period in the prior year.

As stated in Q2, 2019, in accordance with the U.S. GAAP, we have included our revenue recognition methodology a total of $180 million comprised of $50 million for an anticipated milestone from AstraZeneca relating to the filing of the U.S. NDA and $130 million in anticipated milestones from Astellas in connection with the EU MAA filings. When such milestone achievements became probable, included in our third quarter revenue recognition methodology is a $12.5 million milestone associated with the approval for CKD in dialysis patients in Japan.

The timing of when the payments related to these milestones will be remitted to FibroGen depends when the milestones are actually achieved. As noted earlier on this call, our NDA submission is targeted for Q4 this year and we expect the Astellas MAA submission to occur in the second half of the Astellas 2019 fiscal year, which ends March 31, 2020. Based on our latest forecast, we estimate our 2019 ending cash to be in the range of $650 million to $660 million and this range includes the $50 million U.S. NDA milestone.

At September 30, 2019, FibroGen had $666.5 million in cash, restricted time deposits, cash equivalents, investments and receivables.

Thank you. And I would now like to turn the call back over to Jim.

James A. Schoeneck -- Interim Chief Executive Officer

As you've heard, we've made significant progress over the past few months. Looking forward, we will continue to drive our products, programs and organization. Here are some of our areas of focus: First, FibroGen's Board and our search committee has initiated a search to find a truly exceptional leader to be FibroGen's permanent CEO. We'll update you as we have more news of our selection.

For pamrevlumab, we're enrolling our Phase III studies for both IPF and locally advanced pancreatic cancer and will focus on opening additional study sites at increasing patient enrollment. We also look forward to discussions with the FDA to determine the next steps in our Duchenne Muscular Dystrophy program. In China, our focus is on securing reimbursement and the upcoming roxadustat launch. We look forward to updating you on that progress in the coming months as well. For roxadustat, we are completing our NDA submission in conjunction with AstraZeneca and took -- plan to file by the end of this quarter, followed by the European MAA submission through our partner Astellas by March of 2020.

As Pat mentioned, FibroGen is eligible to receive $180 million in filing milestones from our partners and we are also eligible to receive similar scope approval milestones. Finally, we plan to submit the data just presented at the ASN for publication and we'll continue to seek out new indications for roxadustat with our programs in MDS and CIA.

At this point, I like to open up the call for questions.

Questions and Answers:

Operator

[Operator Instructions] And your first question comes from Michael Yee. Michael, your line is open.

Michael Yee -- Jefferies -- Analyst

Thanks very much. I appreciate the questions and congrats on the progress. I know, Tom, would have been proud how do you been there and congrats on the progress. Two questions, one is for Peony, I would just like to understand since there seems to be some investor concern about FDA agreements and FDA sign off on statistical plans. How your general impression was of your meeting with the FDA and why you feel confident about surgical protocols and their signing off of what you had from statistics and why you feel good about that? And my second question is for Jim, in your seat although I appreciate you are the Interim CEO, perhaps you could talk about what your priorities are and what the Board's priorities are at this point, given where the stock is at, where things are and I guess what you're thinking about in terms of priorities from here? Appreciate it. Thanks.

Peony Yu -- Chief Medical Officer

Mike, thank you for the good question. First of all, I wanted to share that we have been in dialog with the FDA in the past six years, and there has been very good understanding about what the Phase III require study would look like and including the size of the study, how to power it and what the primary endpoint and we agree on time to MACE as the primary endpoint and that's how we power for the non-dialysis and the dialysis. And we've also had a very productive dialog with the FDA on the analysis of cardiovascular safety as well as what the efficacy requirement needs to be for this submission. And the most recent conversation with the FDA was at the end of July and we had send it to the FDA a fairly comprehensive briefing package and had a very productive meeting and walking out of it, we felt that we had all the guidance from the FDA we needed to put together a winning submission. And that was about to be out the door this quarter.

Michael Yee -- Jefferies -- Analyst

So you feel no issue, no real concern about the hazard ratios and the upper bounds and all the things that people are talking about, you look at diabetes programs and things like that there is -- your well within that, so you don't feel any concern about that?

Peony Yu -- Chief Medical Officer

No, we have no concern about that. And Mike, as you know, that regulatory assessment is not based on one criterion, but instead, it is based on totality of evidence such as efficacy, safety, what is the medical need. And so based on all discussions and the historical precedents in this therapeutic area and the various conversations we've had with the agency, we are very comfortable with our data where it is now.

Michael Yee -- Jefferies -- Analyst

Okay, thanks. And Jim, just that one question for you.

James A. Schoeneck -- Interim Chief Executive Officer

And Mike, I think our focus is very clear as I mentioned through my closing remarks. I mean, first and foremost, it's filing of the NDA. Second, it's filing through Astellas, the MAA in Europe, behind that is our China and they're securing reimbursement along with the support and our participation in the China launch and with pamrevlumab it's around accelerating, both the number of sites and the enrollment in our two Phase III studies and getting agreement with the FDA on where we're taking the DMD program next. I think beyond that, working with the rest of the Board, it's finding a very capable person to step in and lead the company longer-term.

Michael Yee -- Jefferies -- Analyst

Okay. Thank you.

Operator

And your next question comes from Geoffrey Porges. Your line is open.

Geoffrey Porges -- Silicon Valley Bank Leerink -- Analyst

Thank you very much and thanks everybody for participating in the call. I just wanted to also share my sadness and sympathy about Tom and particularly Poeny, given all the recognition and progress that you've made with roxadustat and pamrevlumab. So one question for Peony if I may, and one question for Chris. Peony, could you share the number of patients in the non-dialysis cohorts that progressed dialysis and the difference in timing in the progression of dialysis and perhaps comment about whether the patient's post progression to dialysis presumably were treated with epo and behaves in the same way the incident dialysis patients. And so was there a benefit from the comparison between roxadustat and epo in the patients who progressed? And then, Chris, could you talk a little bit more about that NRDL listing specifically, have you applied for both dialysis the non-dialysis and what is the size of the non-dialysis patient population who are anemic enough to justify treatment with innovative drugs such as roxadustat? Thanks.

Peony Yu -- Chief Medical Officer

Geoff, you asked a lot of -- that the question is more than one. So I think that you -- it is correct to expect that when 40% of the -- all of the non-dialysis patient pool were indeed already had -- already reach end stage kidney disease meaning eGFR being below 15 and you do expect some patients to required dialysis treatment in this long-term outcome program. And so we the -- now the analysis of these patients is important because transition that will -- represents a transition to dialysis. And we have not had a chance as you see, we have presented a lot of data at the ASN. We have not had a chance to write this one up yet and we agree with you, this is important that we should present in future medical conferences and publications. It's a little bit complicated to report that as a Q&A over here.

Geoffrey Porges -- Silicon Valley Bank Leerink -- Analyst

Was there a benefit--

Peony Yu -- Chief Medical Officer

I'm sorry.

Geoffrey Porges -- Silicon Valley Bank Leerink -- Analyst

Was there a benefit at least in time. Was there a significant difference in the time to progression to dialysis between the two cohorts?

Peony Yu -- Chief Medical Officer

Based on the results from the eGFR change, we believe there should be, but the data needs to further analysis as mainly because the time on treatment between roxadustat and placebo differ.

Geoffrey Porges -- Silicon Valley Bank Leerink -- Analyst

Okay. Thanks, Chris. I'd love to hear from you about NRDL.

Chris Chung -- Senior Vice President of China Operations and Managing Director

Hi, Geoff. So your first question, I believe is whether roxadustat was invited by the Chinese government NRDL negotiations. So first, you're absolutely right, a sponsor is invited, you don't proactively apply. So I think consistent with what AstraZeneca partners have said the two companies are collectively putting a lot of effort in getting into NRDL. At this point in time, we're not discussing if there is an invitation primarily because all invitations either to roxadustat or to other companies are considered confidential and the Chinese government has not published a list of companies invited to negotiate. So I would prefer to wait until the end of the year when the outcomes NRDL is disclosed. I hope you understand.

With regards to the second question, I believe, the question was what is the size -- potential market size of non-dialysis. So I had mentioned just now in my section of the script that there are over 600,000 dialysis patients in China. 90% to 95% of them are anemic. In non-dialysis, if you look at the CKD population, it's actually a 120 million of course mostly they are early stage and they're not necessarily anemic, if you look at Stage 3b,it's about 50% anemic, Stage 4 about 70%, Stage 5 non-dialysis, it's about 90%. If you add those numbers up based on the real world evidence data that we have measurement hemoglobin 10 and below, we believe the addressable market in China for non-dialysis anemia patients below hemoglobin 8 is close to 2 million patients. It's a substandard population, and Geoff, we're very excited because we have an oral therapeutic with the safety profile that we think would greatly expand the addressable market.

Geoffrey Porges -- Silicon Valley Bank Leerink -- Analyst

Great. Thank you very much for that, Chris.

And your next question comes from Adam Walsh. Your line is open.

Edwin Zhang -- Stifel -- Analyst

Hi. This is Edwin on for Adam. Thanks for the question. First question maybe for Peony, for the individual MACE components in the NDD. I guess the events for myocardial infarction and stroke and other datasets has more and FDA will focus on the MACE composite. Can you please further clarify on this NDD MACE dataset?

Peony Yu -- Chief Medical Officer

Yes. So I wanted to reiterate that in our conversation with the FDA. The primary safety endpoint was the composite MACE and there was never any requirement stated for us to on the individual component itself, and I also again remind ourselves that these numbers are fairly -- the number of events are fairly small. And that -- another thing to point out is that the lower bound of the 95% confidence interval on each of these individual components are below 1.0, which is very different than the stroke in treat. And we are looking at the overall picture and the overall safety profile of the drug looking at efficacy, safety as well as what -- how little is on the market for treating the non-dialysis patients.

Edwin Zhang -- Stifel -- Analyst

Okay. My second question is when are you going to talk to [Technical Issues] I mean the statistical analysis plan including the non-inferiority margin. Is there an increase [Indecipherable] meetings in the coming weeks?

Peony Yu -- Chief Medical Officer

I am sorry about questions. Are you asking when we will publish these results, we do plan to write it up as soon as we can and put it in scientific journal.

James A. Schoeneck -- Interim Chief Executive Officer

I think -- Adam, I think the question is when will we talk to the FDA about the statistics and the analytical plan is the question right, when do we plan to talk to them in the coming weeks.

Peony Yu -- Chief Medical Officer

Okay. So the answer to that question is that we had already talked with the FDA about analytical plan and we had made the agreement on the analysis plan. The results that we have presented in the high impact clinical session at the ASN and the numbers I have just presented were based on the agreed analysis plan that we have made with the FDA.

Edwin Zhang -- Stifel -- Analyst

So the non-inferiority margin of 1.3 is already in agreement or not?

Peony Yu -- Chief Medical Officer

So we are talking about the analysis plan, meaning, how do you pool what's the pooling strategy and the analysis plan, how to analyze the data. When you talk about NI margins, you are talking about the standard assessment, right. And as I mentioned earlier that, we expect that all regulators will access the data based on various other -- on the entire application of the NDA. And based on our dialog with the FDA over the past six years and the data as we have shown, we are confident that we do have what it takes for this drug to be favorably evaluated.

Edwin Zhang -- Stifel -- Analyst

All right. Maybe another question for Chris regarding the China market. Can you help us understand more of self-pay market there and the how do you and AstraZeneca book revenue and costs, right now. Is it still 50-50? Thank you.

Chris Chung -- Senior Vice President of China Operations and Managing Director

So, Edwin. With regard to the first question about the self-pay market. So the self-pay market is not large and this is why getting into NRDL, it's an important inflection point for the business. The self-pay market is basically people not getting reimbursement and choosing to pay a 100% out of pocket at a price and it's visible to the market for a roxadustat drug that is higher than the standard of care. We have sales at this point in time. So there is a self-pay market, but we do not expect it to be substantial because of the differential in pricing.

With regard to revenue recognition, FibroGen is the marketing authorization holder of roxadustat in China and under the two invoices role, it is the manufacturing -- it's the marketing authorization holder the books revenues. We have a 50-50 profit share with AstraZeneca. So that is how the 50-50 works. It's not a 50-50 split of the top line. It's a 50-50 split of the profits.

Edwin Zhang -- Stifel -- Analyst

That's very helpful. Thank you.

Chris Chung -- Senior Vice President of China Operations and Managing Director

Welcome.

And your next question comes from Danielle Brill. Your line is open.

Nirav Shelat -- Piper Jaffray -- Analyst

Hi. Thanks for taking my question and congratulations on the data. I just had a couple of questions. This is Nirav on for Danielle, by the way. I was just wondering, would you maybe able to talk a little about whether you're expecting priority review or a normal review with the NDA and if you'd be willing to use a priority review voucher?

Peony Yu -- Chief Medical Officer

This is a very good question. And we believe that the basis for priority review could be because we have a new innovative drug that is potentially better than what is available for treating diseases in patients with serious condition. However, the decision whether to grant as priority review is that one of the FDAs.

James A. Schoeneck -- Interim Chief Executive Officer

So Nirav, the second part of your question, I would not see us using a priority review voucher. But we will indeed request priority review.

Nirav Shelat -- Piper Jaffray -- Analyst

Okay. I see. Thank you. That's helpful. And I guess my second question would be -- would you be able to give us just some color on the MDS study just how it's going -- how the enrollment is going and when we should expect data and along with other agents that are currently in the pipeline for the indication as well? How do you see roxadustat sort of fitting in from a strategic standpoint?

Peony Yu -- Chief Medical Officer

Good question. We do -- we have seen encouraging data from the open label patient of our Phase III study, which is that we will be presenting in the upcoming ASH. And since the other age -- so in terms of the competitive landscape as we believe that because MDS is such a -- MDS anemia is a condition that there is so much need and so difficult to treat, we believe that there is still opportunity for us to make a difference in these patients. And the enrollment is ongoing and we will come back with a -- in the future with timelines on when the study will be completed.

Nirav Shelat -- Piper Jaffray -- Analyst

Great. Thank you so much.

Peony Yu -- Chief Medical Officer

Thank you.

And your next question comes from Paul Choi. Your line is open.

Paul Choi -- Goldman, Sachs & Co. -- Analyst

Hi everyone. Great to see everyone at the ASN meeting and thanks for taking the question. My first question is for Peony and you did state earlier that that the non-dialysis population was not powered to individually assess the various components on MACE. But given the background of the patient population in terms of their EGFR level. Can you give us what is your understanding with regard to the FDA's position on the individual components with respect to when a trial is not powered to show a statistical difference on those individual points given the patients' background population? And then I had a second a commercial question on the NRDL.

Peony Yu -- Chief Medical Officer

So we can share our view on the individual components and what the discussion with the FDA in terms of the requirement for our primary safety endpoints. And as I stated earlier, there was never any explicit expectation on individual components. Now -- but we do believe that the evaluations of the data has to take into account the overall benefit risk at the drug for the patient. So I hope this answers the question.

Paul Choi -- Goldman, Sachs & Co. -- Analyst

Yes, thank you. And then on the NRDL, I know you stated you haven't -- you won't formally communicate whether roxadustat is under invitation to be considered. But assuming it is under consideration. I guess as you think about potential reference pricing and the competitive landscape given the wide availability of epo in China. Can you maybe give us what you think of reasonable range is potentially for pricing on the go forward given the availability and pricing of epo in the China market? Thank you very much.

Chris Chung -- Senior Vice President of China Operations and Managing Director

Absolutely, Paul. So the way we think about pricing in China is as follows: So first of all as value-based pricing, we evaluate the scope of unmet medical need and the pharmacoeconomic consequences of not treating or not treating optimally or not treating safely. We then compared the clinical efficacy benefits of roxadustat based on the China Phase III studies over ESAs and then we had looked at the safety advantages over ESAs and this is all about differentiation on a clinical basis. We also with AstraZeneca believe that roxadustat as a first in class drug and a patented first-in-class drug, of course, to state the obvious deserves an innovation premium because we are bringing a transformative new treatment paradigm to China that above and beyond the clinical benefit to the patient in a quantifiable unmet medical need also supports the country's policy direction of encouraging innovation. So we're hopeful that roxadustat could become an example of companies bringing innovation to China and expecting a return for that delivery. We do not see ourselves being benchmarked against locally manufactured ESA because we think we're highly differentiated product with clinical benefits and we believe we deserve an innovation premium.

Obviously Paul at the end of the day, it's about budgetary concerns and budgetary considerations of the Chinese government and affordability for the patient. So at the end of the day should there be an NRDL negotiations, pricing would not just be what we would like to assert, but what the country can actually afford. So we'd be eager to see what that balance is should there be an NRDL negotiation, but that is -- our pricing strategy in terms of what we believe is a fair pricing for roxadustat.

Paul Choi -- Goldman, Sachs & Co. -- Analyst

Thanks for taking our questions.

Okay. And our next question comes from Joel Beatty. Your line is open. Joel perhaps you're muted on your end.

Joel Beatty -- Citi -- Analyst

Sorry about that. Okay. Can you hear me now.

James A. Schoeneck -- Interim Chief Executive Officer

We can, Joel.

Joel Beatty -- Citi -- Analyst

All right. Okay, great. So the -- my first question is on quality of life benefit from the Phase III program. I believe that there were some initial data presented in the top line data, but then I didn't see anything on quality of life ASN? Should we still consider the quality of life effect to be in line with the top line press release and how important will quality of life data from the Phase III program be for marketing the drug?

Peony Yu -- Chief Medical Officer

Joel it is a quick questions. Yes. Our data is consistent with what we had reported in top line and we just have so much to put together for the ASN and we do look forward to present the results in future conferences and publications. As you know, one of the manifestations of anemia is for patients who is fatigue and enlarging quality of life. Thank you.

Joel Beatty -- Citi -- Analyst

Okay. And then maybe one other question. Can you talk about the indication you plan to pursue for roxadustat? Thanks.

Peony Yu -- Chief Medical Officer

Yes. So we and our partners believe that roxadustat has the potential to become the anemia drug. So various kinds of anemia beyond CKD, and as we have presented, we already have ongoing trial in MDS anemia and in chemotherapy induced anemia and there are additional anemia types that are in considerations such as anemia in multiple myeloma patients and anemia of inflammation. There has been extensive effort to evaluate all these types of anemia and more.

Joel Beatty -- Citi -- Analyst

Thank you.

Operator

Okay. And there are no questions at this time.

James A. Schoeneck -- Interim Chief Executive Officer

Well, in closing, I'd like to thank you for your attention and support. I also want to thank the senior management team and all the dedicated employees at FibroGen in the U.S. and in China, who are committed to bringing novel, innovative medicines to patients around the world, fulfilling the vision that Tom set for the company 25 years ago.
