(Operator Instructions) As a reminder, this conference is being recorded. It is now my pleasure to introduce our first speaker, Dolly Vance, who is Rigel's Executive Vice President of Corporate Affairs and General Counsel. Thank you. Ms. Vance, you may begin. -------------------------------------------------------------------------------- Dolly A. Vance, Rigel Pharmaceuticals, Inc. - Executive VP of Corporate Affairs, General Counsel & Corporate Secretary [2] -------------------------------------------------------------------------------- Welcome to our first quarter 2020 financial results and business update conference call. The financial press release for the first quarter was issued a short while ago and can be viewed, along with the accompanying slides for this presentation, in the News & Events section of our Investor Relations page on our website, www.rigel.com. As a reminder, as a reminder, during today's call, we may make forward-looking statements regarding our financial outlook and our plans and timing for regulatory and product development. These statements are subject to risks and uncertainties that may cause actual results to differ from those forecasted. A description of these risks can be found in our annual report on Form 10-K for the year ended December 31, 2019, and subsequent filings with the SEC, including our Q1 quarterly report on Form 10-Q. Any forward-looking statements are made only as of today's date, and we undertake no obligation to update these forward-looking statements to reflect subsequent events or circumstances. At this time, I would like to turn the call over to our CEO, Raul Rodriguez. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [3] -------------------------------------------------------------------------------- Thank you, Dolly, and thank you for joining us on our first quarter 2020 financial and business update call. Also joining me on the call is Tarek Sallam, our Vice President of Marketing; our Chief Medical Officer, Wolfgang Dummer; and Dean Schorno, our CFO. I'd like to begin on Slide 5. First, I'd like to say that during these extraordinary times, the entire team at Rigel hopes you and your families remain safe and healthy. Importantly, we would like to thank all of the health care workers for their selfless efforts, which are absolutely vital. From a company perspective, our primary goal at this time is to ensure the safety and health of our employees and patients. Rigel is taking actions across all of our business areas in order to continue executing on our strategy amid these challenging times. We are monitoring the impact this will have on our business going forward, and we'll continue to adapt to the environment and provide updates as necessary. Now on to Slide 6. Rigel has 4 key value drivers: growing TAVALISSE in the U.S. ITP market, capturing value in the global ITP market via collaborations, creating and capitalizing on warm autoimmune hemolytic anemia opportunity and expanding our pipeline of programs. Q1 of 2020 was certainly not what we imagine it would be, to say the least. Nonetheless, we adapted to our environment, transitioned to virtual platforms and made important progress. In the recent quarter, we continued to grow sales on a year-over-year basis, reporting a 57% increase compared to the first quarter of 2019. We are very pleased with this given everything that is going on externally. This is a testament to the high-quality commercial organization we have in place as well as the highly differentiated and effective products we provide. In the global market, we're excited to have received approval for fostamatinib in Europe this past January. It will be marketed under the brand name TAVLESSE by our partner, Grifols. The label we received is very attractive and exactly what we were looking for. It's broad and allows us to compete effectively in Europe. With this approval, we recognized $43.1 million of revenue during the quarter, which included a $20 million milestone that we received in February. We look forward to Grifols making our product available to patients, which we expect them to do this quarter. Our next potential commercial opportunity is in warm autoimmune hemolytic anemia, which we believe is an even larger opportunity for Rigel. AIHA is another autoimmune disease like ITP where the body produces antibodies against a hematologic cell type, in this case, red blood cells. There's a real unmet need for these patients given that there's no approved product for this indication. And based on the progress we've made to date, we are in a position to potentially be the first product on the market. We have generated encouraging data from our Phase II trial of TAVALISSE in warm autoimmune hemolytic anemia, giving us the confidence that we have to move forward in our Phase III trial. We have opened up over 80 sites across 22 countries for this Phase III trial to date. We have randomized 41 patients, and we're making very good progress prior to the impact of recent events. Wolfgang will provide an update and also review our ongoing interactions with the FDA in just a few minutes. Lastly, we are very excited about further development that is taking place in all our programs. In addition to AIHA, we are exploring other potential opportunities for TAVALISSE, one of which is in the treatment of COVID-19 pneumonia and related conditions. Wolfgang will discuss this rationale in his section. Our RIP1 and our IRAK1/4 inhibitors are in Phase I trials, and we are very excited for the potential of both of these assets. IRAK and RIP are 2 of the most attractive immune targets in biopharmaceuticals today. And based on our early data, our molecules have demonstrated characteristics. It gives us a lot of optimism for their potential. We continue to make progress in our discussions to secure a codevelopment and copromotion agreement for one or both of these assets, and we believe we'll be able to do so by year-end. Firstly important at this time is that we have a solid financial position, and we have continued to strengthen by adding $30 million in cash from a combination of milestone payment from our partner Grifols and the use of our debt facility from MidCap. Dean will discuss this a bit later in the presentation. Moving on to Slide 7. We are excited about these key value drivers because they address areas of important medical need and our major market opportunities. We are well positioned to capitalize this across these areas, even in this environment. ITP is a $1.1 billion market and growing in the U.S. outside the U.S., ITP market is about $900 million. We think that warm autoimmune hemolytic anemia has potential to be a $1 billion market in the U.S. similar to the current size of the ITP market. And our pipeline continues to offer Rigel tremendous opportunities for business development activities and clinical trials in the near future -- near term and in the future. With that, I'll turn the call over to Tarek. Tarek? -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [4] -------------------------------------------------------------------------------- Thank you, Raul. Our current commercial efforts are centered around our first marketed product, TAVALISSE, which, as you see on Slide 9, is a kinase inhibitor indicated for the treatment of thrombocytopenia in adult patients with chronic ITP who have had an insufficient response to a previous treatment. Let's move to Slide 10. I'd like to further elaborate on our first quarter performance that Raul highlighted earlier. We generated net product sales of $12.7 million, which was an increase of 57% compared to $8.1 million in the first quarter of last year. There were 1,398 bottles shipped to patients and clinics during the quarter, which excludes any change in bottles remaining in distribution channels, which Dean will review in his update. This was encouraging given the typical headwinds pharmaceutical companies face in the first quarter, particularly for oral specialty products, which are created by insurance reauthorizations, patients starting new plans and Medicare resets. What was, of course, atypical for the quarter was the rapid outbreak of COVID-19. Leading up to the month of March, we were excited to get out in front of our customers with our recent clinical data in second-line patients, which I'll discuss in a few minutes, and deliver on our strategic priorities for the year despite these typical first quarter headwinds. But then, as we all know, the current pandemic quickly changed the dynamic of how we all work and interact with one another. However, we did see an uptick in March that has persisted through April driven by a combination of both refills and new patient starts. Additionally, our persistency rate remained in the 54% range for the quarter. All of these are important indicators of future growth. All said, we are pleased with the progress and foundation we have in place. While we certainly could not have anticipated COVID-19 occurring when it did, let me share with you what we are doing in this new environment to support our health care providers, their ITP patients and the TAVALISSE business and how we believe that we exit this period of challenge well positioned. Moving on to Slide 11. I'd like to take a few moments to provide you with an assessment of the health care environment our customers are facing during this pandemic. A majority of our physician customers and clinics have restricted access or a fully shut down their drug company sales teams. In fact, many clinics and institutions are only seeing critically ill patients. They have even begun to triage their malignant disease patients that do not have imminent health risk or an acute need and are asking them to remain at home and wait to schedule follow-up appointments. This is obviously an incredibly challenging environment for our providers, their patients and, of course, for us to attempt to conduct business as usual. Fortunately, we're in an age in which virtual technology is accessible and easy to utilize. Virtual engagements are a necessity for any measure of success in sales for the foreseeable future, and we are seeing offices increasing their telemedicine capabilities. As a relatively small and nimble organization, we were able to quickly adjust by making many of our in-person activities virtual, including one-on-one physician conversations, in-services to support new prescribers and their staff as well as providing existing customers with ongoing support remotely. These engagements have been well received, and we will continue to optimize their effectiveness. Some additional feedback from our customers is that given the current shelter-in-place orders throughout the country, having an oral option is certainly perceived as a potential benefit. Recently, we launched a physician product sampling program. The objectives of the program are to encourage physician trial of TAVALISSE and assist in patient identification. And we're seeing an increased utilization of our sampling program, which we have been able to facilitate remotely. We're extremely excited to have a program in place to help physicians and patients access TAVALISSE while limiting the risk of exposure to COVID-19 with fewer office visits. Turning to Slide 12. I'd like to share why we believe that we're poised for success once the current environmental situation normalizes. As a reminder, one of our key priorities for 2020 is increasing the utilization of TAVALISSE in earlier lines of therapy and accessing larger patient pools, represented by the chart on the left side of the slide. We feel that the second-line data analysis, summarized on the right side of the slide, is critical in our ability to execute on that strategy. As a reminder, this is a retrospective analysis of patients in our Phase III clinical trials that received TAVALISSE as a second-line therapy. And of these patients, 78% achieved a response. This is a similar response seen by other agents in this setting. This data was presented at the American Society of Hematology Conference in December of 2019. We then trained our teams and launched new materials in mid- to late February, so awareness of the second-line data is quite low. Well, our field teams now have these materials and are sharing them virtually. As you can imagine, they're excited to get out in front of their customers more broadly with this new messaging. And once they're fully deployed, this truly represents an opportunity to share with health care providers a new perspective on TAVALISSE's clinical utility and further supports our story in the earlier-line treatment setting as the environmental situation normalizes. So with that, I'd like to turn the call over to Wolfgang. Wolfgang? -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [5] -------------------------------------------------------------------------------- Thank you, Tarek. Good afternoon, everybody. I'll begin on Slide 14. As you know, fostamatinib is currently in an ongoing Phase III pivotal trial in warm autoimmune hemolytic anemia. Here's an update on our progress and how we are adapting in this current environment. Currently, we have 41 patients randomized into the study, which is nearly half of our target enrollment number. We had very good recruiting momentum until early March when the COVID-19 pandemic spread widely, and clinical trial sites began to temporarily postpone screening. While this is effectively delaying enrollment for now, I'd like to emphasize the importance of the established operational foundation of our trial. We have over 80 trial sites in 22 countries that remain active. Hence, as soon as the COVID-19 situation normalizes, we should regain momentum rather quickly and efficiently. And since some countries are likely to normalize quicker than others, we can restart enrollment on a country-by-country basis, which will provide a competitive enrollment advantage. During the quarter, we also had productive conversations with the FDA about the program. As a reminder, the trial is placebo-controlled with a 1:1 randomization to fostamatinib or placebo. Originally, the sample size was planned to be 80 patients. We have increased the trial size slightly to 90 patients, which adds incremental powering to the study and could help mitigate any potential missing data caused by COVID-19. We are still working with the FDA on finalizing the most appropriate durability measure. Since there is no drug approved for AIHA and we have the only AIHA trial in our pivotal Phase III, we are setting the standard and work with the FDA to establishing this durability criteria. Turning to Slide 15. Like others in the industry, Rigel has been forced to rapidly adapt our Phase III clinical trial conduct due to the current COVID-19 pandemic. The FDA recently provided guidance for the conduct of trials during COVID-19, which provides some flexibility that we are utilizing. For example, patients can get blood draws locally from their primary care physicians and have them analyzed at their local lab, or some site visits can be replaced by virtual visits to collect basic safety information so that patients' risk of exposure to the virus can be kept as small as possible. We also maintain a laser-sharp focus on collecting all obtainable data in order to maintain a complete and robust set for the patients that are already in the study. Regarding enrollment completion, right now, there is a COVID-19-related delay. At this time, we cannot give clear guidance on what the delay will be exactly. We will provide updates as the global COVID-19 impact becomes more certain. But as I have alluded to earlier, this enrollment pause should not impact our goal to have the first treatment to market for AIHA with all its first-mover advantages. If anything, we could potentially extend our enrollment leads given the large numbers and the geographical range of our sites that remain active. Slide 16. Moving to additional pipeline options beyond AIHA, you see COVID-19 on this slide, and I will speak to the scientific rationale for fostamatinib in potential activities in COVID-19 in a little while. Given the broad potential for fostamatinib in our SYK inhibition program, we consider the large pool of indications, and we have narrowed the search down to the most attractive opportunities, which we plan to pursue. Executing on an additional label indication for fostamatinib will enable us to take full advantage of the exclusivity for this molecule, which is expected to be into 2032. In addition to fostamatinib, our IRAK1 inhibitor, the only inhibitor molecule of both IRAK1 and IRAK4 pathways, continues to progress in the program and remains in good position. In preclinical studies, it has shown to block inflammatory cytokine production in response to TLR and IL-1 receptor family signaling, and a Phase I human healthy volunteer study achieved its proof of mechanism and demonstrated favorable PK characteristics. Finally, we recently completed the multiple ascending dose stage of our Phase I study with our systemic RIP1 inhibitor. Importantly, we have identified a dose range that is safe and is well within expected clinical efficacy. We confirmed the 14-hour half-life for these doses, which is quite significant as it should allow for once-a-day dosing. And as mentioned previously, we also plan to identify RIP inhibitor CNS molecule in the near future to move into the clinic as well. Now let me shift gears and briefly share our considerations for the use of fostamatinib in the treatment of COVID-19 patients. We truly believe there is a compelling scientific rationale for the drug to have benefit in treating COVID-19 pneumonia as well as associated acute respiratory distress syndrome. Let me take you through that. Slide 17. As you may know, pneumonia is one of the most severe complications associated with COVID-19. Severe cases can progress to ARDS, which requires invasive ventilation due to low blood oxygen saturation, and frequently leads to death. Interestingly, this rapid progression often happens when the immune system has already begun to make antibodies against SARS-CoV-2, and the viral load actually decreases. That means that, really, the immune system causes the severe pathology, not just the virus. The SYK pathway is involved in multiple mechanisms, as illustrated on this somewhat simplified slide. So look at the image on the right, please, and I'll walk you through this. So if you look at the virus particle, in the early stages of infection, the replicating virus causes lung epithelial cell destruction and release of so-called damage-associated molecular patterns, or DAMPs; and pathogen-associated molecular patterns, PAMPs, which binds to C lectin receptors, so-called CLRs. Signaling through CLRs can lead to excessive inflammatory cytokine release in coagulopathy from vascular endothelial cells and to massive neutrophil activation and cytotoxicity by a process called NETosis. All these events can damage the lung and also other organs, such as the kidneys and the heart. SYK inhibition with fostamatinib can reduce this highly inflammatory process. Now if you look towards the left side of the image, you can see the second main mechanism for a hyperreactive immune system. As a response to viral infection, our immune systems begin to make anti-SARS-CoV-2 antibodies, and these antibodies find the virus, inform immune complexes with the virus, which then binds to Fc gamma receptor-expressing cells such as macrophages, dendritic cells and monocytes. And that can, in some patients, induce excessive release of inflammatory cytokines such as IL-1 beta, IL-6 and IL-8. So here, too, SYK inhibition with fostamatinib can ameliorate this resulting cytokine storm and prevent organ damage. Fostamatinib is the only approved SYK inhibitor that may interfere with the pathology of COVID-19 at multiple points through multiple cell types and could, therefore, work in COVID-19-related organ damage, pneumonia and ARDS of viral or also other etiologies. Now this is not an entirely new concept as we do have preclinical data from a model of ARDS. On Slide 18, you see an executive summary of those mouse experiments. Here, R406 is the active metabolite of fosta used in this model and essentially the same as fosta. On the left, you see the histology of lung tissue and the 4 different circumstances. Upper left, you see healthy lung tissue with clear alveoli where transport of oxygen into the blood happens. On the top right, you see the same thing when only fostamatinib is administered with no negative impact on the lung. But looking at the lower left, you see acute respiratory distress syndrome induced by LPS, which led to massive inflammation, lots of fluid and debris in the alveoli, making oxygenation of the blood different or insufficient. On the lower right, you can see that fostamatinib had a clear beneficial effect on this pathology. And not surprisingly, as depicted on the panel on the right, this led to survival of the mice with ARDS that were treated with fostamatinib. So what are we going to do with all of this? We are currently seriously contemplating to get the drug into the clinic in one form or another. That could mean providing fostamatinib to some hospitals to support one or more investigator-sponsored trials to generate initial data. It could mean all the way to potentially a Rigel-sponsored clinical trial. We will keep you posted. With that, I'll hand over to Dean for a review of the financials. Dean? -------------------------------------------------------------------------------- Dean L. Schorno, Rigel Pharmaceuticals, Inc. - Executive VP & CFO [6] -------------------------------------------------------------------------------- Thank you, Wolfgang. I'm on Slide 20. For the first quarter of 2020, we shipped 1,393 bottles to our specialty distributors. We shipped 1,398 bottles to patients and clinics, which is comparable to the fourth quarter where we shipped 1,422 bottles to patients and clinics. As in the prior year, we did see typical first quarter reimbursement issues, such as the resetting of copays and the Medicare doughnut hole. Incrementally, we did start to see the effects of COVID-19 in the latter part of the quarter. Also during the quarter, and for the first time, we saw 5 bottle reduction in bottles that remained in our distribution channels, resulting in a total of 591 bottles at the end of the quarter. We reported net product sales from TAVALISSE of $12.7 million, a 57% increase compared to the first quarter of 2019. Our net product sales from TAVALISSE were recorded net of estimated discounts, charge-backs, rebates, returns, copay assistance and other allowances of $2.7 million. Our gross-to-net adjustment, which is approximately 17.5% of gross product sales, we currently expect our gross-to-net adjustment to remain in the 18% to 19% range throughout 2020. In the first quarter, we did see a sequential reduction in net product sales, resulting primarily from the changes in the bottles remaining in our distribution channels and, to a lesser extent, the impact of COVID-19 in the latter part of the quarter. Specifically, in the fourth quarter of 2019, we saw a 96-bottle increase in bottles remaining in our distribution channels compared to a 5-bottle reduction in the first quarter of 2020. The effect of this change in bottles remaining in our distribution channels was approximately $1 million when comparing the change in the fourth quarter of 2019 to the first quarter of 2020. Before we move on from net product sales, let me comment briefly on our expectations for the second quarter of 2020. While we would have expected to move past the seasonality of the first quarter caused by the reimbursement issues that we discussed and would have anticipated accelerated sequential growth like we saw in Q2 of 2019, the impact of COVID-19 in our business that started in the latter part of the first quarter continues and remains uncertain. As Tarek highlighted, we've made great strides in optimizing our ability to access our physician community remotely and to provide the many patients suffering from chronic ITP in the U.S. with access to TAVALISSE. Once the significant impact and restrictions caused by COVID-19 are behind us and the future begins to normalize, we expect to see continued strength and growth in our business. Currently, our long-term view of the opportunity for TAVALISSE remains unchanged. On to the next slide. In addition to net product sales, Rigel's contract revenues from collaborations was $43.1 million for the 3 months ended March 31, 2020. As a reminder, during the quarter, we announced that we received European Committee approval of our MAA for fostamatinib for the treatment of chronic ITP in Europe. With this approval, the company received a $20 million nonrefundable payment from Grifols, which is composed of a $17.5 million milestone payment and a $2.5 million creditable advance royalty payment. In addition, $25 million of the $30 million upfront payment that we received from Grifols in Q1 of 2019, which had been previously deferred, will no longer be repayable by us to Grifols. Given this information as well as the performance of certain research and development services, we recognized approximately $43.1 million as collaboration revenues in the first quarter of 2020. The remaining deferral amount of $2.2 million will be recognized as revenue as we complete certain research and development activities, mainly related to the conduct of our autoimmune hemolytic anemia Phase III clinical trials. Moving on to cost and expenses. Our cost of product sales was approximately $155,000 for the first quarter of 2020. Total cost and expenses were $34.7 million in the first quarter of 2020 versus $31 million in the first quarter of 2019. The increase in total costs and expenses was primarily due to third-party costs related to Rigel's ongoing pivotal Phase III study in warm autoimmune hemolytic anemia, research and development costs related to other clinical programs and personnel-related costs, partially offset by stock-based compensation expense. As we look towards 2020, we continue to expect our total cost and expenses to increase by approximately 15% to 20% as compared to 2019 as we continue our commercial expansion and further our research and development pipeline. We ended the quarter with cash and short-term investments of approximately $95.9 million. Incrementally, we access the second $10 million tranche from our $60 million term loan facility with MidCap Financial, which we received on May 1. The facility provides the company with access to an additional $40 million, which is subject to the achievement of certain conditions. Rigel currently has sufficient supply of TAVALISSE tablets and drug substance to meet the needs of our U.S. ITP commercial business as well as our collaborative partners and clinical trials worldwide. Finally, I'd like to say that we will continue to undertake efforts to prevent or minimize disruptions to our business and operations while monitoring for new developments related to the evolving COVID-19 pandemic. At this time, we don't yet know the full impact of such disruptions on our business, operations or financial condition. With that, I'd like to turn the call back over to Raul. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [7] -------------------------------------------------------------------------------- Thank you, Dean. As you can see that the COVID-19 pandemic has had an impact varying degrees on all areas of the business, but what we are trying to achieve has not changed. They will be unavoidable and have unavoidable impact on our business in the short term. But fundamentally, we remain on track. This is driven by the resilience and focus of our employees and their commitment to our patients. We will continue to grow TAVALISSE in the U.S. ITP market using virtual engagements to communicate across all the vehicles we use. We are excited about the use of TAVALISSE in earlier lines of therapy and the data that we have to support this positioning. Similarly, we look forward to European patients that suffer from ITP also having access to TAVLESSE and will support our excellent partner, Grifols, in their efforts. We will work to complete the enrollment of our AIHA Phase III study. The patient need in warm autoimmune hemolytic anemia is no less real, no less pressing or no less important today than it was earlier this year. We will give them a much needed treatment option. We will explore how TAVALISSE could potentially provide patients with COVID-19-related pneumonia a much needed new therapy. We will continue to advance our RIP1 and IRAK1/4 programs and put in place a partnership for one or both of these important assets. We will work harder, smarter and more thoughtful to accomplish what we set out to do. With that, I'd like to open the call up to your questions. ================================================================================ Questions and Answers -------------------------------------------------------------------------------- Operator [1] -------------------------------------------------------------------------------- (Operator Instructions) Our first question comes from the line of Yigal Nochomovitz with Citigroup. -------------------------------------------------------------------------------- Yigal Dov Nochomovitz, Citigroup Inc, Research Division - Director [2] -------------------------------------------------------------------------------- First question is related to the prescribing patterns for TAVALISSE in light of COVID. So I understand you've shifted to telehealth primarily. But what happens for new patients? Is it possible for a hematologist to prescribe TAVALISSE to a new patient just via telehealth? Or do they actually need to see the patient? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [3] -------------------------------------------------------------------------------- Thank you, Yigal. I hope you're doing well. I'll ask Tarek to answer that. -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [4] -------------------------------------------------------------------------------- Sure. And thanks for the question, Yigal, and absolutely an appropriate one given these unique times. So when I was referring to the telehealth capabilities that we're seeing out there with our providers and our subsequent ability to interact with them virtually, in fact, a lot of our activities that have taken place in March as well as continuing into April, as I had articulated, are supporting new prescribers. So not only are we ensuring ongoing support of existing prescribers but, to answer your question simply, yes, we've absolutely been able to support new hematologists, new HemOnc clinics with virtual in-services, onboarding, even so far as sending via snail mail materials or even digitally so that their nurses and their staff are able to educate patients, whether they're educating patients in situ, live in person in the clinic or they themselves are doing it through telehealth mediums. So I'll be honest, I've been very impressed by both our internal team as well as our external customers' ability to adapt to meet the needs of new patient identification. Hopefully, that answers your question. -------------------------------------------------------------------------------- Yigal Dov Nochomovitz, Citigroup Inc, Research Division - Director [5] -------------------------------------------------------------------------------- Yes. No, that's very helpful. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [6] -------------------------------------------------------------------------------- Go ahead. Yigal, you had a follow-up, I think, as well. -------------------------------------------------------------------------------- Yigal Dov Nochomovitz, Citigroup Inc, Research Division - Director [7] -------------------------------------------------------------------------------- Yes. Yes. I was -- I did. I just wanted to make sure I understand -- understood Dean's comments a little better with respect to the sequential decline for 1Q '20 versus Q4 '19, which I understand was driven by COVID in the latter part of the quarter as well as the typical headwinds. But with respect to 2Q '20, to the extent that you can comment, are you saying or are you preparing the market to expect another sequential decline given the COVID headwinds? Or is that reading into it too much? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [8] -------------------------------------------------------------------------------- Dean, go ahead. -------------------------------------------------------------------------------- Dean L. Schorno, Rigel Pharmaceuticals, Inc. - Executive VP & CFO [9] -------------------------------------------------------------------------------- Yes. So a couple of things, Yigal. The description of the reduction, the sequential from Q4 to Q2, we had a 96-bottle increase in inventory in Q4, a 5-bottle decrease in Q1, so 101 bottles at a bit more than $9,000 per bottle on an average net sales price across our business. That's almost $1 million. So as you look at the graphic that we showed that, it showed the reduction in Q1 of 2020. That was our purpose there. With respect to our view going forward, what we've said at this point is, and just kind of to reiterate what Tarek said, is that -- our view is that -- we haven't given guidance to date. We did see a sequential -- we saw an uptick in our business in March that persisted into April, but we just don't know the full effect and the access that will become available to us. And we just haven't provided more information beyond those comments. But let me pause there and ask Tarek or Raul to add any incremental color. -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [10] -------------------------------------------------------------------------------- Yes. Yes. Thanks, Dean. This is Tarek. So Yigal, the other thing, too, just to reinforce this, as Dean articulated, while we're not providing guidance and certainly, like many organizations, COVID-19 is adding an unknown variable, I spoke a little bit about the opportunity as well. And so while as an organization, as a commercial organization, we would have loved to have had our field face-to-face, in front of our customers, talking about the second-line data, particularly as we had launched it towards the mid- to late February time frame. That still represents opportunity for us. And so using the vehicles that we have in place, we are consistently delivering that message, whether to new prescribers or existing prescribers as they're thinking about the appropriate patients for TAVALISSE. So just consider that as part of the balance of really how we're actually executing out there and delivering messages. Clearly, we can't wait to get in front of them, in person, when things abate, but we are certainly delivering those messages virtually right now. -------------------------------------------------------------------------------- Yigal Dov Nochomovitz, Citigroup Inc, Research Division - Director [11] -------------------------------------------------------------------------------- Okay. Great. That's helpful. And this one might be best suited for Wolfgang. With respect to the new initiatives you've announced regarding COVID-19 trials in the SYK pathway, I just want to get a sense, was this something that originated from internally within your -- among your scientists? Or were you approached by academic groups that saw the potential for this drug to potentially treat COVID-19 patients? I'm just trying to get a sense as to how it originated and the extent of the investment that you would make in this sort of program. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [12] -------------------------------------------------------------------------------- I can answer the latter part of that, Wolfgang. -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [13] -------------------------------------------------------------------------------- Yes, the answer to your question is both. We have been approached by renowned institutions who are interested in using this drug. At the same time, of course, internally and based on the data that I've shown you, we have thought that might be there for this compound. And so this came at the right time. How much money would we spend, Raul, do you want to take that? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [14] -------------------------------------------------------------------------------- I do. A couple of comments, we were interested in acute lung injury, ARDS. Prior to the COVID epidemic, the experiments that Wolfgang had showed on Slide 18 was published, something we've been very interested in exploring ourselves because ARDS is a substantial opportunity correlated to many other diseases, not just COVID-19. So when this came about, we knew that this was a good opportunity for us to consider. And what we did is continue having discussions about it. And we were subsequently approached, as Wolfgang said, by institutions that are already working in this area, doing trials, testing molecules. And so this is an opportunity for us to explore the use of our product in this important new area. And obviously, we'll take advantage of it as fast as we can to put it into human testing. So how much money it will take, I think I can't say just yet because we don't have that done yet. And so right now, we're exploring this investigator-sponsored trial just because they are the fastest way to begin testing the molecule in this setting. -------------------------------------------------------------------------------- Operator [15] -------------------------------------------------------------------------------- Our next question comes from Chris Raymond with Piper Sandler. -------------------------------------------------------------------------------- Allison Marie Bratzel, Piper Sandler & Co., Research Division - Research Analyst [16] -------------------------------------------------------------------------------- This is Ally Bratzel on for Chris this afternoon. So I think, first, just on the FDA interactions regarding the AIHA trial, could you clarify what the driver was there for increasing the sample size to 90 patients? Was that purely in response to potential COVID-19 interruptions? Or was that upsizing always a possibility as part of a preplanned interaction with FDA? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [17] -------------------------------------------------------------------------------- Yes. I'll ask Wolfgang to answer it, then I'll add some color. -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [18] -------------------------------------------------------------------------------- Yes, sure. So there was some overlap. We wanted to meet with the FDA and we rearranged for a date and, at the same time, COVID-19 began. Our original driver was to increase the sample size slightly because it gives us a little bit more incremental power. And actually, to be a specific, 90 would allow for 1 additional placebo responder to get a response and, with a 25% delta, still hit statistically significant. So there was sort of a precaution. And since enrollment went well, we thought this is a very good idea. Now in the times of COVID-19, it does also mitigate against the potential risk that a handful of patients are not getting enough data to be fully evaluated. Right now, that situation looks pretty good. We are looking very carefully into the amount of missing data and help patients come to the site and get their blood draws, and it looks actually pretty good. The sites are doing a very good job. But this is -- the increase of sample system to 90 is a little bit of an added risk mitigation against that. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [19] -------------------------------------------------------------------------------- So the answer is both, Ally. And I think we were, prior to this COVID thing, enrolling 8 to 9 patients a month in a pretty good clip, and we're seeing good trajectory. I think we'll get back to that once these sites begin screening patients again. So it's worth that extra little other securities for both reasons. -------------------------------------------------------------------------------- Allison Marie Bratzel, Piper Sandler & Co., Research Division - Research Analyst [20] -------------------------------------------------------------------------------- Okay. Makes sense. And then maybe shifting to ITP, a question on the 4 months' refill rate. That's gone really nicely since, I think, Q4, you first started describing that at around 45%. And now it's up in the mid-50s. But I think we saw it quarter-on-quarter at around 54%. So could you just talk about kind of the drivers that are impacting that? Was there some Q1 seasonality impact that maybe would allow that to be flat in Q4 and Q1? And then maybe just talk about how we should think about that refill rate growing or maybe beyond the mid-50s staying steady in the mid-50s through 2020. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [21] -------------------------------------------------------------------------------- Tarek, you want to take that? -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [22] -------------------------------------------------------------------------------- Sure. And Raul, feel free to layer on. So a great question in regards to our persistency rate. As I shared, we're seeing approximately a persistency rate at 4 months for the quarter at 54% and, as you articulated, some good progress since launch -- actually, a significant progress since launch. I think as we think about -- to your question, about what are the drivers, what are the behaviors and how do we potentially foresee that looking forward, well, certainly, we don't have a crystal ball. I think what we've articulated in the past is that as clinicians and their staff become more familiar with the products, understand how to manage the disease with this specific product, understand how to educate their patients about AEs and onboarding of it as well as, frankly, we talk about the specific patient type that they're using it in, we believe that all these factors are going to impact and then correspondingly improve the persistency rate. One of the key we think to the persistency rate and its potential growth in the future is really the line of therapy because, obviously, later-line patients have poor prognosis and potentially cycle on and off therapies more frequently. And so we believe, particularly that the second-line data and as we move TAVALISSE into regular usage in the second- and third-line setting, that, that is going to also correspondingly impact the persistency rate. So hopefully, that answers your question. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [23] -------------------------------------------------------------------------------- Ally, we've just started this in terms of moving into earlier lines of therapy with this new data from the ASH meeting, as Tarek pointed out in his presentation. So really, our presence in that segment, those earlier segments, is really very small, and that provides tremendous opportunity to grow. And the opportunity would manifest itself in more patients but also more patients staying on drug longer, higher persistency. And it's not just month 4 but really across the entire curve that we expect to increase with as we get into those earlier lines of patients who have just a better response to products generally and ours specifically, with 78%. So I think that's pretty exciting. You should expect to see that continue to increase. And you're right, we were 45%, now we're at 54%, and it should continue to move upward. -------------------------------------------------------------------------------- Operator [24] -------------------------------------------------------------------------------- Our next question comes from Do Kim with BMO Capital Markets. -------------------------------------------------------------------------------- Guyn Kim, BMO Capital Markets Equity Research - Analyst [25] -------------------------------------------------------------------------------- I was hoping if you could talk more specifically about the dynamics of how COVID impacted TAVALISSE sales in the first quarter. Other biopharma companies have been reporting that oral therapies have been seeing early refills and increase in 90-day scripts, causing a temporary pull-forward in sales. Is that something you also saw? Or is it just difficulty in getting new patients and some slippage in existing patients? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [26] -------------------------------------------------------------------------------- Let me take the first stab at that, and Tarek, I'll ask you to comment as well. Thank you, Do. I hope you're doing well. So really, Q1 is typically a challenging quarter. It was -- remember, last year, we had a quarter that was about flat. And this quarter, we were thinking it was going to be about flat. And then in March, we usually see an uptick. We saw an uptick. It was not as pronounced as maybe we were expecting it to see, and that's what caused this moderation of growth that we came in largely flat, maybe slightly below where we were last quarter. And really, it had impact in many ways, doctors and patients not seeing their doctor on a regular basis. So some of that is insurance resets. Some of that is they just didn't want to go see a doctor under COVID conditions. It's hard to separate the 2 out, frankly, and say it was due to this and that other than, in Q1, you see the impact of both those effects, insurance resets as well as the COVID keeping patients from moving forward. And so we saw that, and that's what depressed our growth. So as you saw in March, we did see an uptick. It was not as pronounced, and that continued into April. Tarek, any other observations? -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [27] -------------------------------------------------------------------------------- No. I mean it's a great question, Do. And I think to Raul's point, it's hard to pinpoint the specificity in terms of acceleration due to long-range, like 90-day, refills and things like that. We haven't necessarily seen that level of granularity impacting our business. Ultimately, with the headwinds we've seen from a reimbursement and insurance perspective, as Raul articulated, we really have seen momentum build in March and April. And obviously, the timing of this and our inability to be face-to-face with our customers is an area that we would have rather, obviously, been out there in person. And so to articulate whether it's A or B is a little difficult for us. But needless to say, we're really encouraged by just the level of engagement. I can tell you, just based on sheer interest alone, physicians are amenable to meeting with our both commercial and medical field forces. They're excited to hear about the new data. So just using that as a little bit of a litmus test to indicate that there's a willingness and a need for this information, I will say, I'm actually pretty encouraged by that. -------------------------------------------------------------------------------- Guyn Kim, BMO Capital Markets Equity Research - Analyst [28] -------------------------------------------------------------------------------- Okay. Great. That's very helpful. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [29] -------------------------------------------------------------------------------- Do, if I could just add one quick comment there, what's interesting, maybe a little surprising to me, is that in the quarter, Q1, we saw a decline in inventories at our distribution channel -- or in the distribution channel. Usually, we see a bottle increase. As Dean said, in Q4, we saw almost 100-bottle increase in inventories. And this quarter, Q1, we saw a 5-bottle decrease, no increase in inventory, which created that unfavorable comparison. Actually, that was a surprise to me. I would have expected some increase in inventories just because of all that's happening. That didn't occur in Q1. -------------------------------------------------------------------------------- Guyn Kim, BMO Capital Markets Equity Research - Analyst [30] -------------------------------------------------------------------------------- Right. No, that makes sense. And for Grifols launch in Europe, in your communications with them, has there been any discussions in a potential delay in that, considering how hard Europe has been hit by the pandemic? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [31] -------------------------------------------------------------------------------- Well, what they've told us, and actually, they put out in their press release last week, is that the product will be available to patients in Europe this quarter. And so that's good. Doctors can actually write the script and have it filled. In terms of their active promotion of the launch, it's just very difficult to execute on that right now. No doubt they'll delay some of that activity. But the product will be available this quarter, which is good to see. And when things clear up a bit, they'll move forward. Interesting, different countries in Europe are suffering through this pandemic very differently, Italy and Spain, maybe one extreme. But it seems that some other countries, Germany is frankly handling it quite well, as well as we expected, not a lot of disruption. The Scandinavian countries, Norway, for example, are doing well. And so it's highly varied in Europe. It's not -- maybe not too dissimilar to the U.S. in terms of different regions. But in some places, I expect them to move forward more quickly than in other places. -------------------------------------------------------------------------------- Guyn Kim, BMO Capital Markets Equity Research - Analyst [32] -------------------------------------------------------------------------------- Okay. And last question, probably for Wolfgang, in the clinical study for TAVALISSE to treat COVID pneumonia and ARDS, are you thinking about a particular severity of the disease where TAVALISSE will be most effective? And as you have all these other therapies, antivirals, looking for the more moderate of patients, will -- would you think that TAVALISSE would be effective in the most severe of patients? -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [33] -------------------------------------------------------------------------------- Yes. So if you -- look, TAVALISSE is not an antiviral, it's an immune modulator, right? So I see the greatest opportunity, certainly, in particular, initially, in the cases that have advanced to pneumonia, and that could start as early as just verified pneumonia but no invasive ventilation required. But I could also see potential in the patients who are already on a ventilator. And as you know, they have like very high mortality rates. Given what I have shown you and how SYK inhibition might work, I think, definitely, that will be the place to start. Once you get to a point where you have established safety and efficacy at that stage, you could move yourself forward and, say, well, shall we use this as soon as you have any type of respiratory symptoms, but that will be probably the second step. -------------------------------------------------------------------------------- Operator [34] -------------------------------------------------------------------------------- Our next question comes from the line of Tessa Romero with JPMorgan. -------------------------------------------------------------------------------- Tessa Thomas Romero, JP Morgan Chase & Co, Research Division - Associate [35] -------------------------------------------------------------------------------- I hope you were all doing well. First one from me on wAIHA, if I could. So you have widespread sites geographically, which I think could be favorable in rebuilding momentum when the COVID pandemic normalizes. Sort of what are the key push-pull levers to consider on the enrollment side and, potentially, still meeting the prior mid-2021 data timing? I think you have a 24-week or a 6-month primary end point for the study. And then I have a follow-up. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [36] -------------------------------------------------------------------------------- Sure. I'll ask Wolfgang to add, but I will just preface it by saying we think that this is a very attractive opportunity, and the product will be a very important product for patients suffering from warm autoimmune hemolytic anemia. So our view of the opportunity really hasn't changed at all. And the reason we believe so strongly in this is that we opened up 80 centers across the world in order to execute on this trial as fast as we can. And that does give us a lot of geographic diversity that lays the impact of COVID being very different in different European countries. And so it will help us a good deal, and I think we'll get back to enrolling patients at a clip of 8 or 9 patients a month once the sites are back focused on this. But that will be different, and they'll come back at different speeds, and it's hard to predict right now what that speed differential might be, which is why it's harder for us to say this is when we think it will be completed. Wolfgang, do you want to add any other thoughts on that? -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [37] -------------------------------------------------------------------------------- Yes, you covered most of the answer for the question. I guess we have -- so basically, what we discussed is you need to be comfortable and your patient needs to be comfortable to participate in the study, and that means you want to come to your study visits, so that we can draw your blood and all these type of things. And in the -- obviously, in the height of the pandemic, the comfort level wasn't very high. I would say now that things are more and more reopening and beginning to normalize, we can start thinking about this again. But again, it -- things change very quickly these days. But once we feel it is safe for the patients to come back to the site and participate in the study, then reopening of enrollment could be considered. -------------------------------------------------------------------------------- Tessa Thomas Romero, JP Morgan Chase & Co, Research Division - Associate [38] -------------------------------------------------------------------------------- Okay. That's helpful. And I may have missed it in some earlier comments, but just a quick one from me. What -- sort of in the height of the pandemic, what were you seeing on NRxs versus TRxs versus kind of what you're seeing sort of in late March? I think you said there was an uptick into April. I'm just kind of trying to get at -- can you give any more kind of color on if it was new patients that were kind of declining or if it was some of your existing patients? Yes, any additional color you can provide on that point would be helpful. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [39] -------------------------------------------------------------------------------- Sure. I'll take a stab at doing that. And Tarek, if you could follow on that. We saw continuing activity in both new patients and continuing patients and pretty good reaction in terms of that. We are very positive on the start of the year in terms of what we are expecting to see, especially given the earlier-line data that we had presented at the ASH meeting. And so we were seeing good, and as expected, performance in the business across new and established patients. And then surprising, this COVID hit at the month where you see an uptick. We saw a bit of an uptick but not maybe as profound as you would have expected. Tarek? -------------------------------------------------------------------------------- Tarek Sallam, Rigel Pharmaceuticals, Inc. - VP of Marketing [40] -------------------------------------------------------------------------------- Yes, Raul. Tessa, to your question, I think that last point, Raul, is probably the only point I would have just layered on specifically, is that, as you can imagine, Tessa, these are chronic disease patients. And for a lot of oral therapies like TAVALISSE, not just ourselves, kind of they tend to kind of work their way through these reimbursement hurdles in the first couple of months. And so with that dynamic that we've seen, we have seen a more robust uptick in the past to March. So I think that last point that Raul articulated is just kind of the key points. -------------------------------------------------------------------------------- Operator [41] -------------------------------------------------------------------------------- (Operator Instructions) Our next question comes from the line of Kristen Kluska with Cantor Fitzgerald. -------------------------------------------------------------------------------- Kristen Brianne Kluska, Cantor Fitzgerald & Co., Research Division - Analyst [42] -------------------------------------------------------------------------------- I hope everyone on your team remains well. So my first question is, as it relates to the warm AIHA trial, I noticed on clinicaltrials.gov that you made some modifications and added new centers during April. Were these centers part of the plan? Or have you made any changes as it relates to -- a result of the pandemic? And also, are you looking to potentially explore any backup centers in specific geographies as you continue to monitor the situation? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [43] -------------------------------------------------------------------------------- Thanks, Kristen. I hope you're well as well. I'll ask Wolfgang to answer that. -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [44] -------------------------------------------------------------------------------- Yes. No, so we opened sites according to our plan -- to our originally existing plan. There was no change. To your other point, I think with our 22 different countries, we are geographically pretty well prepared for a reopening. And as I said in my script, this could be a site by -- a country-by-country approach, right? So if we see that countries like Germany come back to normal a little bit quicker, we can certainly open enrollment there faster than in something very hard hit like Italy, for example. So I think we are extremely well prepared, as prepared as we can be for the time of reopening and resuming of randomization. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [45] -------------------------------------------------------------------------------- Kristen, look -- thank you, Wolfgang. Kristen, if I could add on that. April -- clinical trial.gov had additional sites opening in April, that's -- I don't think that's correct. I think it may have been just a delay in updating the site because I don't think we've added any sites in April. But one thing that's useful to think about is, as we went forward with this and had the sites open, our thought was having a patient enroll, and then not having to make -- able to make any of their visits, would have not been a useful advance in the program. We really prefer to have the patients where we're confident that they'll be able to make their visits because, otherwise, they're not going to be useful patients to study and enroll. -------------------------------------------------------------------------------- Kristen Brianne Kluska, Cantor Fitzgerald & Co., Research Division - Analyst [46] -------------------------------------------------------------------------------- Okay. So while a majority of centers are postponing enrollment, is there anything that your team or investigators can do during this time to try to find patients that could be eligible once things start to open up again? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [47] -------------------------------------------------------------------------------- Well, the patients are still there, and we know that the patients need a new product such as this. So that hasn't changed. Their willingness to come to a clinical trial site on a regular basis during stay-at-home orders is limited because of that. And also some of the centers, especially centers that are part of major health care facilities in some of these cities, are also reluctant to undertake additional obligations like monitoring patients and so forth when they're focused on other things. So for both of those reasons, it's quite understandable. But as the pandemic is not a substantial an impact in some countries of, say, Germany, for example, they'll be back to focusing and patients will be back to visit the clinic, looking for potential therapies and, as part of that, we'll consider enrolling in our trial. But we're following that very carefully. All the centers are places where there are patients. We know they have patients that are potential patients for our clinical trial. Wolfgang, anything to -- anything further than that? -------------------------------------------------------------------------------- Wolfgang Dummer, Rigel Pharmaceuticals, Inc. - Executive VP & Chief Medical Officer [48] -------------------------------------------------------------------------------- Yes. Maybe just to add, it is such that all of these sites have an open eye on who might qualify for that study before they even screen the patient, meaning they have a list of names that they know they have AIHA. Some of them might qualify now. Some of them, they observe for a while until the hemoglobin goes down. So that list of names exists for most of the sites. And once things normalize and we say, well, let's continue enrolling, you can reach out to these patients and then put them in a real screening and see if they qualify for enrollment and randomization. So there is activity ongoing. -------------------------------------------------------------------------------- Kristen Brianne Kluska, Cantor Fitzgerald & Co., Research Division - Analyst [49] -------------------------------------------------------------------------------- Okay. And my last question here is, last quarter, you listed some potential indications you might look at for fostamatinib beyond chronic ITP and warm AIHA. Have your thoughts changed here at all? Or is the same potential list of indications what you're considering at this time? -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [50] -------------------------------------------------------------------------------- I think it's a similar list with the addition of ARDS, and COVID ARDS specifically, or COVID pneumonia more broadly. That obviously was not something that, a quarter ago, we were thinking about. And now it's risen quite quickly, as you have surmised, in terms of our level of interest, and we're looking at that very carefully. -------------------------------------------------------------------------------- Operator [51] -------------------------------------------------------------------------------- There are no further questions at this time. I would like to turn the floor back over to Mr. Raul Rodriguez for any additional closing comments. -------------------------------------------------------------------------------- Raul R. Rodriguez, Rigel Pharmaceuticals, Inc. - President, CEO & Director [52] -------------------------------------------------------------------------------- Well, thank you for your interest. These are times that I think are extraordinary. Never have we gone through such a period of time. And -- but I have to say I'm incredibly impressed and delighted to be part of an organization that works so diligently to continue their work, whether it's at home, whether it's out in the field and on virtual calls. It's been very impressive how quickly and thoughtfully our staff has made that transition, and I think a tribute to the dedication to the goals that we have to provide the product to our patients, to provide them additional product opportunities to treat their illnesses, AIHA, COVID ARDS. We will continue that effort and make sure that we continue to make progress every single week, whether it's in our living rooms, our bedrooms, our homes or back in the office, I hope soon, or in the labs. So thank you for your support and look forward to providing further updates. Take care. -------------------------------------------------------------------------------- Operator [53] -------------------------------------------------------------------------------- This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
