Analyst · JP Morgan. Your line is now open
Thank you, Kristen. Good morning everyone. We believe we have a great story to share with you this morning. Throughout the first half of this year, we continue to make good progress against our strategic initiatives. And the headline continues to be solid execution. The commercial teams delivered $29 million in Auryxia revenue in the second quarter. The highest quarter since launch, 21% year-over-year growth and 26% growth versus the first quarter of 2019. We reached the settlement with ANDA filer for Auryxia that reinforces the strength of our Auryxia IP. And with respect to vadadustat, the clinical team continue to knock it out of the park with the first regulatory submission for marketing approval of vadadustat, which was filed by our collaboration Mitsubishi Tanabe or MTPC in Japan. This JNDA submission is a significant milestone for both companies. We believe this is just the beginning of an exciting lineup of announcements expected in 2020 and beyond. While there is still much work ahead of us. I believe we have tremendous opportunities to advance our mission to better the lives of people living with kidney disease, and deliver significant value to all our stakeholders. We have been very purposeful in developing our strategy to achieve this mission and it is great to see the benefits of our work coming to light as the team continues to systematically execute on our priorities. I will start with progress in our Phase III clinical program for vadadustat. Vadadustat is our investigational oral HIF-PHI that is designed to stimulate endogenous production to a more physiologic level for adult patients with anemia due to chronic kidney disease or CKD. Our JNDA filings particularly impressive, not only because it is the first regulatory submission for marketing approval of vadadustat, but also because we believe is may establish vadadustat as the first oral HIF-PHI to file for approval for the treatment of anemia due to CKD in both dialysis dependant and non-dialysis dependent patient populations in a major market. Importantly, this submission was supported by positive top-line data from two Phase III active-control pivotal studies in Japan that we announced together with MTPC in the first quarter. Turning to our global Phase III preclinical program. In April we completed enrollment in INNOVATE our global clinical studies designed to enable regulatory filings for vadadustat for the treatment of anemia due to CKD in dialysis dependent patients. We enrolled a total of nearly 4000 across the two INNOVATE studies and we continue to expect top-line data readouts in Q2 of next year subject to the approval of MACE. With respect to PROTECT our global clinical studies designed to enable regulatory filings vadadustat for the treatment of anemia due to CKD in patients not on dialysis. Patient enrollment has continued to be strong and I’m pleased to announce that as we expect to complete enrollment shortly we are no longer accepting new patients at the screening. We continue to expect top-line data readouts in mid-2020 subject to the approval of MACE. We have a tremendous amount of confidence in the program that we have design for vadadustat and believe we are well-positioned for clinical, regulatory and commercial success. For example, both INNOVATE and PROTECT are designed to assess non inferiority for efficacy and cardiovascular safety for vadadustat using an active-control darbepoetin alfa an injectable ESA which is the current standard of care. We believe this structure will enable a straightforward collection and analysis of MACE across the relevant studies and ultimately a clear data readout. Importantly our program includes multiple secondary efficacy and safety endpoints to assess other clinically and hence commercially important areas of differentiation TSA, including the incidence of thromboembolic events, hospitalization for heart failure and effect on blood pressure. And in non-dialysis dependent CKD subject the progression of kidney disease. If successful at these studies, we expect that vadadustat to be the first HIF-PHI in the U.S. and EU markets where data directly comparing its outcomes to the current standard of care in both dialysis and non-dialysis patients. We believe this data will be extremely relevant for physicians, patients and payers as they make important decisions about patient care. I think it is important to note here that because of our non-dialysis study was designed with an active-control, patients in this population that progress to dialysis during this study will be able to stay on study drug. As a result, we expect to be able to compare how these new-to-dialysis patients on either of the control drug or vadadustat do as they transitions to dialysis and move forward. We will have data across that continuum of care for a large number of patients. We believe that this will be very valuable data from a regulatory and commercial standpoint, especially when paired with our incident patient study in INNOVATE as the new-to-dialysis patient population is a particular interest, because the event rate in the first year of dialysis is generally much higher. It also makes our MACE analysis much more straightforward. We believe another key advantage of our program is it was designed with a basic philosophy that not every patients needs are the same. As a result, we designed our clinical program with the potential for dosing flexibility with once-daily dosing for non-dialysis dependent CKD patients, and daily oral three times a week dosing for dialysis dependent CKD patients. Lastly, we designed these studies after extensive dialogue with the FDA and European regulators. We have prospectively defined and agreed to non-inferiority margins with the FDA and EMA. And we also agreed with the FDA on the key components of our statistical analysis plan. Turning to our commercial products Auryxia , the only oral iron tablet approved in the U.S. to treat both dialysis dependent CKD patients for hyperphosphatemia and non-dialysis dependent CKD patients for iron deficiency anemia IDA. For Q2, Auryxia a ratio revenue increased 21% to $29 million and total Auryxia prescriptions increased 22% to $49,200. The team is doing a great job executing on our near-term growth initiatives. We continue to see solid demand for Auryxia within our hyperphosphatemia indication, which we believe represents most of our product revenue. In fact, the prescription demand we have seen in the first four weeks of the third quarter is the highest of any quarter since Auryxia was launched, affirming our confidence that Auryxia is on a growth trajectory. We believe continued execution on our growth initiatives, and underlying market demand will drive increased revenue for Auryxia across the second half of the year. A favorable outcome from our continuing work with CMS to restore coverage for Auryxia IDA indication would represent the opportunity for upside. We look forward to providing more specific revenue guidance for Auryxia early next year, after we get a few more quarters of solid excellent under our belt. In looking further ahead, what I'm most excited about with respect to Auryxia is how we are continuing to advance its long-term growth story and impact the lives of people living with CKD. We have always believed that Auryxia to have a valuable role in treating patients beyond our current indications. We are encouraged with recent data published in the Journal of the American Society of Nephrology that we believe supports this potential. We have mentioned this study previously, it was an investigator initiated study, funded by Keryx prior to the merger and conducted by Colorado care with Dr. Jeff Block as the principal investigator and lead author of the publication. In a single site, 203 pages and trial that comparative six dose of ferric citrate or Auryxia to standard of care in patients with advanced CKD. The authors concluded that ferric citrate effectively managed multiple biochemical parameters and was associated with significant improvements in hemoglobin, TSAT and ferritin and significant decreases in serum phosphorus, and FGF 23 compared to the standard of care. The encouraging finding was that in this small study, the investigator was able to show a statistically significantly lower incidence of progression to dialysis, transplant or death, fewer hospitals admissions and fewer days in the hospital in those patients who received ferric citrate. No related serious adverse events occurred and the most common related adverse event in ferric citrate to the patients for gastrointestinal. These findings are very encouraging and with we really authors conclusion that this pilot study warrants further investigation, which we are now exploring with a number of KOL advisors, who are also excited about the data and about Auryxia's potential. It is great to see the new policy initiatives like the advance American kidney health initiatives, aligning with this vision and placing a priority on these outcomes while at the same time seeking to reduce more than $100 billion expense annually in the U.S. treat chronic and end stage renal disease. Although its early, we believe this environment creates opportunities not only to improve patient care, but also enhance the value of Auryxia with both prescribers and payers. As you know we have been intensely focused on protecting the value of Auryxia. We believe the ANDA settlement we announced earlier this week, reinforces the strength of our Auryxia intellectual property and does not allow par to have a generic entry until March 20, 2025.This was another great example of solid execution in the quarter that is well worth noting and we are very pleased with the outcome. Lastly, we are also pleased with the collaboration partner Japan Tobacco and its subsidiary Torii who market for ferric citrate in Japan under the trade name Riona, investing with the goal of adding a second approved indication for Riona. Earlier in July we announced and they reported positive top-line results from a pivotal Phase III comparative study evaluating Riona for the treatment of IVA in adult patients in Japan. They also stated that they expect to file for this additional indication upon successful completion of their Phase III program. Wrapping up we feel good about the opportunities we have today, and the team is thrilled with the prospect of continuing to advance vadadustat and enhancing Auryxia’s potential. And with that, I will turn the call over to Jason.
