Operator
Ladies and gentlemen, thank you for standing by and welcome to the Urovant Sciences Fiscal 2019 Second Quarter Financial Results Conference Call. At this time, all participants are in a listen-only mode. [Operator Instructions] As a reminder, today's conference is being recorded.
I like to turn the conference over to Ryan Kubota, Executive Director of Investor Relations. Please go ahead, Mr. Kubota.
Ryan Kubota -- Head of Investor Relations
Thank you, operator. Good afternoon and thank you all for joining Urovant's Fiscal 2019 second quarter financial results conference call. With me today are four members of our leadership team; Keith Katkin, Chief Executive Officer; Christine Ocampo, Chief Accounting Officer; Dr. Cornelia Haag-Molkenteller, Chief Medical Officer; and Ajay Bansal, our new Chief Financial Officer and Senior Vice President of Business Development.
Today after market close, we issued a press release containing detailed information on our quarterly results. You may access the release on our company website, urovant.com.
During our call, we will be making forward-looking statements, including statements regarding our plans, strategies for the clinical development of vibegron and other treatments for urologic diseases. Listeners are cautioned that all of our forward-looking statements are based on our current expectations and assumptions, which are subject to numerous risk factors that could cause our actual results to differ materially. Accordingly, we advise listeners to review the forward-looking statements disclosure in today's press release and the Risk Factors section of our Form 10-K as well as our Form 10-Q which we filed later this week.
With that said, I will now turn the call over to our CEO, Keith Katkin. Keith?
Keith Katkin -- Chief Executive Officer
Thank you, Ryan, and my thanks to all of you for joining us today. First, I would like to welcome Ryan Kubota, our new Head of Investor Relations. Ryan joins us from Molina Healthcare and he looks forward to speaking with all of you in the upcoming weeks.
This has been an exciting quarter for Urovant. We achieved key clinical milestones for our OAB development program for vibegron and now with the substantial financial commitment and enhanced commercial support from Sumitomo Dainippon Pharma, we are in an optimal position for developing Urovant into a leading specialty urology company.
Last week Roivant Pharma and Sumitomo entered into a definitive agreement for the creation of a broad Sumitomo Roivant strategic alliance, which upon close will result in Sumitomo becoming the new majority shareholder of Urovant Sciences. In conjunction with the definitive agreement with Roivant, Urovant also entered into an agreement with Sumitomo, whereby Sumitomo has committed to provide Urovant with the following things. First, a $200 million low interest, interest only five-year term loan facility. Second, certain minority shareholder protections. Third, access to enhance commercial support from the Sumitomo U.S. franchise Sunovion. And finally, expected financial support through profitability.
As you know, BSP is a well-known top 10 Japanese listed multinational pharmaceutical company with an extensive history of innovation in drug development and commercialization. The company generated over $4 billion in revenue last year through the commercialization of several large pharmaceutical drugs in the United States, including the blockbuster drug Latuda. We look forward to this promising new alliance with Sumitomo as we prepare for the commercial launch of vibegron. Our new drug application or NDA filing and launch preparations for vibegron are well under way and we're excited to have the strategic support and proven commercial resources of Sumitomo. This partnership should greatly optimize Urovant Sciences' commercial approach to the U.S. market with enhanced resources for drug distribution, operations and managed care support.
Now regarding this quarter results, we achieved another pivotal milestone with the completion of a long-term extension of the Phase III EMPOWUR study of vibegron for patients with overactive bladder. The study achieved its primary objective confirming vibegron safety -- favorable safety and tolerability profile and demonstrating further improved treatment benefit on the key overactive bladder symptoms over the 40-week extension period. In addition, we completed our pharmacokinetic study of vibegron as a crushed tablet. These results are expected to support labeling for administration of vibegron as a crushed tablet in in soft food, a potentially significant advantage for elderly OAB patients who have trouble swallowing. With these key studies complete, final preparations for our NDA for vibegron for patients with OAB are progressing quickly for filing an early 2020 if not sooner.
Other important business highlights include initiation of part 2 of the Phase III COURAGE trial, which will assess both efficacy and safety of vibegron in men with OAB and BPH, a patient population for which no product is currently approved. Continued enrollment of female patients into IBS-associated abdominal pain trial with top line results expected in 2020, and finalization of the Phase 2A protocol for URO-902, a novel injectable gene therapy product, which is planned to commence patient enrollment by the end of the fourth quarter of 2019.
With that, I'll turn the call over to our Chief Medical Officer, Dr. Cornelia Haag-Molkenteller, who'll provide more detail to our clinical programs.
Cornelia Haag-Molkenteller -- Chief Medical Officer
Thank you, Keith. As mentioned, we have achieved key milestones for OAB program for vibegron and continue to make excellent progress across our other clinical development programs. We are pleased to be report positive long-term data from the 40-week extension of the Phase III EMPOWUR study of vibegron in patients with overactive bladder. This was a double-blind 40-week extension of the 12-week placebo controlled EMPOWUR Phase III study. 505 patients from the EMPOWUR study received blinded study medication of either vibegron 75 milligram or tolterodine 4 milligram extended release. Those already on vibegron or tolterodine from the EMPOWUR study remained on their respective treatment for a total of 52 weeks of exposure and the placebo patients from the EMPOWUR study were randomized to either vibegron or tolterodine for 40-week treatment period. Of the 505 patients in the long-term extension, 85% finished the trial at very high completion rate for 40-weeks study. The primary objective of the long-term study was safety and tolerability and the secondary objective was sustained efficacy of vibegron for reduction in micturitions, urge urinary incontinence and urgency episodes.
We are pleased to report that in addition to demonstrating favorable safety and tolerability profile. The study showed further improved treatment benefit on key overactive bladder symptoms and the improvement from 12-week onwards was sustained over the entire 40-week extension study. Among the 52-week EMPOWUR vibegron treatment group, the reduction micturitions at week 52 was minus 2.5 episodes per day from a baseline of 11.3 episodes and the reduction in urgency episodes was minus 3.4 episodes per day from a baseline of 8 episodes. In addition, vibegron demonstrated sustained efficacy for urge urinary incontinence, the most bothersome and embarrassing symptom of OAB. The reduction urge incontinence was minus 2.2 episodes at week 52 from a baseline of 3.2 per day. Overall, a total of 61% of vibegron patients achieved a 75% reduction of their baseline urge, incontinence episodes after 52 weeks of treatment and 41% of vibegron patients were totally dry meaning without incontinence episodes after 52 weeks.
We are also particularly pleased to see that vibegron achieved numerically better efficacy than tolterodine to active control at every time point measured. The adverse event profile of vibegron from the extension study was consistent with the 12-week EMPOWUR Phase III study and first event rates were below 10% and the adverse event rate for hypertension was in the range as for tolterodine alternative to active control. These data reinforce our belief that vibegron has the potential to become the best-in-class all OAB treatment.
Plans for publication and presentation of both the EMPOWUR Phase III study and the long-term extension results are well under way. Recently a detailed view of the EMPOWUR results was presented globally at the International Continence Society meeting in Gothenburg, Sweden in September 2019. Presentations of the long-term data are planned for future scientific meetings in 2020. In addition to the completion of the long-term extension of the EMPOWUR Phase III study this quarter, we also completed the Phase I study on food effect with the final vibegron 75-milligram tablet and testing of pharmacokinetic parameters, if the tablet is crushed and administered applesauce. The study results will be used to support the proposed labeling for administration of vibegron without or with food and as a crushed tablet in soft food, which is an important potential benefit as many elderly patients have difficulty swallowing.
Regarding a supplemental development program from vibegron in men with OAB and benign prostatic hyperplasia or BPH. The Phase III COURAGE program, the independent Data Safety Monitoring Board reviewed the safety data from the 82 patients enrolled in part one of this trial and agreed that the study can now move to part 2 of the trial, which -- in which over 1,000 patients will be enrolled. Part 2 of the Phase III trial will assess both efficacy and safety of vibegron in the OAB and BPH population. A pivotal milestone as there currently is no FDA approved product specifically indicated for overactive bladder in men with BPH. The co-primary endpoints are reduction micturition frequency and urgency episodes for 24 hours, key secondary endpoints are reduction in nocturia episode, the awakening at night to avoid prostate symptom scores and safety. In addition to the initiation of the part 2 of the Phase III COURAGE study, patients from part 1 have enrolled into the long-term extension study, which will follow patients for a total exposure of 52 weeks.
Regarding our clinical program for IBS-associated abdominal pain, study continues to enroll female patients with IBS-associated pain, who are then randomized to either 75-milligram of vibegron or placebo. The primary endpoint is a 30% reduction in abdominal pain intensity on a 11 point rating scale at week 12 for IBS-D, which is IBS with Diarrhea. The responder is defined as a subject with at least 30% decrease in the worst abdominal pain compared to the weekly baseline average. Secondary endpoints include the global rating scale and safety in particular, the lack of negative effects of stool frequency or consistency. We expect to report top line data from this study in 2020. Finally, regarding our novel injectable gene therapy for OAB, URO-902, a Phase 2a protocol preparations are proceeding per plan for the start of the study in the U.S. and we expect to start patient enrollment by the end of fourth quarter 2019.
Now, I'll pass on to Christine for a financial update.
Christine Ocampo -- Chief Accounting Officer
Thank you, Cornelia. In addition to the financial results summarized in the press release, you can find additional information at our upcoming Form 10-Q, which will be filed later this week. Research and development expenses were $17.8 million for the second quarter of 2019 compared with $20.7 million for the same period in the prior year. In the second quarter of 2019, research and development expenses were comprised of cost related to clinical development specifically, the open-label phase of our Phase III OAB trial as well as our ongoing studies in OAB BPH and abdominal pain associated with IBS. When comparing the two quarters, the decrease in R&D expenses is primarily due to a decrease in costs associated with the Phase III OAB trial, as both the double-blind an open-label phases of this trial were completed in 2019.
General and administrative expenses were $7.4 million for the second quarter of 2019 compared with $3.6 million for the same period in the prior year. The increase in G&A expenses is primarily attributed to personnel costs, including share-based compensation professional fees such as legal and accounting, commercial readiness costs and general operating expenses. Total operating expenses were $25.2 million for the second quarter of 2019 compared to $24.3 million for the same period in the prior year. Cash used in operations was $24.5 million for the quarter ended September 30, 2019, an increase of $2 million as compared to the immediate prior quarter ended June 30, 2019. Net loss was $25.7 million or $0.85 per share for the second quarter of 2019 compared with a net loss of $24.6 million or $1.23 per share for the same period in the prior year. At September 30, 2019, the balance of total cash and cash equivalents was $67.8 million.
Now looking ahead to the remainder of fiscal 2019, we expect our cash used in operations to be approximately $26 million to $28 million per quarter, excluding milestone payments of $12.5 million, which will become due on filing of our NDA. For the third quarter of 2019, we expect our total operating expenses, excluding milestone payments, to be in the range of $30 million to $32 million, as we plan to recognize expense for prepaid expenses that are associated with the Phase III OAB trial. With the additional $200 million loan facility from Sumitomo, we expect to be funded well into 2021. In addition, we expect Sumitomo will continue to fund Urovant Sciences operating needs through profitability which will provide financial stability as we move forward with the vibegron launch and our additional development program. And finally, now that we have passed the one-year anniversary of our initial public offering, we believe it is prudent financial planning to have an active shelf and an aftermarket facility or ATM in place. As such in the near term, we expect to file a $200 million Form S-3 registration statement, which will include a $50 million ATM.
And with that financial update, I will turn the call back over to Keith.
Keith Katkin -- Chief Executive Officer
Thanks, Christine. Before I move to my closing remarks, I would like to introduce you to Ajay Bansal, our new Chief Financial Officer and Senior Vice President of Business Development. Ajay brings over 16 years of finance, business development, accounting and mergers and acquisitions experience in start-up and larger biotech environments, as a Chief Financial Officer. He has led the growth and strategic capabilities for several leading and innovative biotechnology companies. Ajay also brings a very unique set of experiences to Urovant, which I believe will enhance and strengthen our strategic, business development and financing capabilities.
Ajay, would you like to say a few words?
Ajay Bansal -- Senior Vice President, Business Development and Chief Financial Officer
Thank you, Keith. Firstly, I'm just delighted to be here at Urovant. I believe it's a terrific time for me to be joining Urovant with vibegron NDA filing coming up soon, followed by launch preparations and now with enhanced financial resources at our disposal, the next two years, three years are going to be very exciting and critical in the evolution of Urovant into a leading specialty urology company. I'm impressed with vibegron's clinical data to-date and I believe that it has the potential to become a best-in-class therapy for OAB patients. I'm delighted to be a part of this journey and look forward to interacting and meeting with several of you over the coming weeks.
With that, let me turn the call back to Keith for closing remarks.
Keith Katkin -- Chief Executive Officer
Thanks, Ajay. I would like to reiterate our segments for the new alliance with Sumitomo, which should provide a long-term financial stability for Urovant, while also providing access to a global platform of enhanced commercialization resources and other significant advantages as we prepare for the launch of vibegron.
In closing, the second fiscal quarter of 2019 were key milestones across all aspects of our business, and we look forward to several upcoming milestones that will continue to drive us toward the goal of developing Urovant into a leading specialty urology company. These -- some upcoming milestones include filing our NDA for vibegron in overactive bladder by the first quarter of 2020 with the possibility of accelerating the file in the late fourth quarter 2019. Initiation of part 2 of the Phase III COURAGE trial, which will assess both the efficacy and safety of vibegron in men with OAB and BPH. Continued enrollment in our Phase II IBS associated abdominal pain study with top line data readout expected in 2020 and the start of patient enrollment into the Phase IIa of our novel injectable gene therapy for OAB, URO-902 by the end of the fourth quarter of 2019.
With that, I'd now like to open up the call for questions, operator?
Questions and Answers:
Operator
[Operator Instructions] Our first question is from Ritu Baral from Cowen. Your line is open.
Unidentified Participant
Hey, guys this is Dishant [Phonetic] on for Ritu Baral. Two questions from our end. The first is, any expectations for a differentiation in terms of the labeling for vibegron versus Myrbetriq? So just like a better safety language. And the second question is, given that the patent is set to expire on Myrbetriq in 2023, how do you see that affecting uptake in the next five years and if generics of insert hit the market and possibly insurance coverage? Thanks for the question.
Keith Katkin -- Chief Executive Officer
Sure, appreciate that. And let me try and take those off one at a time. I think first as it relates to the differentiation, we actually think that our package insert will likely be differentiated from mirabegron in a number of different ways. First, let me touch on the efficacy parameters, I think first and potentially most importantly, we believe that the charts in our label will demonstrate a two-week onset of action as our Phase III study demonstrated vibegron's efficacy at two weeks, and this compares very favorable -- favorably to mirabegron's starting dose of 25-milligrams which the package insert clearly states that it takes up to eight weeks to work. So in our market research that has resonated very strongly with both doctors and patients.
Additionally, I think as we've discussed before, based on our discussions with the FDA, we believe that we may be able to have some additional efficacy endpoints that no other OAB drug has had in their package insert. This would include the outcome of urgency, given our strong performance in the Phase III on the urgency endpoint and also responder analyzes that many of the things that Cornelia was talking about. For example, the percent of patients that experience a 75% reduction in the urge urinary incontinence episodes, things of that nature. So we think we'll be well differentiated from an efficacy perspective. From a safety perspective, there are two, we think there'll be a number of points of differentiation. First and foremost, our lack of drug-drug interactions particularly on 2D6. If you look at the mirabegron label, they certainly do inhibit 2D6 and from our market research, almost 40% of patients that are taking their vibegron are on drugs that are metabolized to be on that pathway and therefore giving those patients a new option where they don't have to worry about drug-drug interactions, we believe we'll be very meaningful for them as well. In addition, we have demonstrated that vibegron has no impact on QTc, whereas mirabegron we know as supra therapeutic doses does have that impact on QTc.
And then finally just to wrap up, our single convenient dose will certainly be an advantage versus vibegron's dose titration and our ability to be crushed, particularly for the elderly patients that have problems swallowing, whereas mirabegron can't be crushed because it's an extended-release formulation. So we think there's a whole host of reasons why physicians and patients will prefer vibegron over mirabegron and we very much look forward to getting that NDA and getting FDA approval.
As it relates to your question about the generic entry of for mirabegron. Right now, we're uncertain whether that will happen at the end of 2023 or sometime in 2024, but irrespective, it will give us about three years of marketing with them before the generic is introduced and we think that's plenty of time to establish vibegron as a best-in-class OAB product. Additionally, as we've had discussions with payers -- even as recently as last week, the payers do not view this as a highly managed category, they have communicated to us, they would not expect to have a step through of mirabegron to use vibegron, whatsoever. It's just not cost effective for them to have to do that within their plans. So all in all, we are extremely excited at the problem and how its emerged from vibegron in the studies and how it'll be able to effectively position ourselves versus mirabegron. Appreciate the question.
Unidentified Participant
Great. Thanks a lot.
Operator
Our next question is from Eric Joseph from JPMorgan. Eric, your line is open.
Turner Kufe -- JPMorgan -- Analyst
Hey, good evening. This is Turner on for Eric. I'm just hoping you could elaborate a bit on the commercial support you were able to receive from Sumitomo and if there are any specific aspects of distribution and/or sales force that you are able to leverage and does this change your plan to 150-person sales force and initial efforts to target primarily urologists in long-term care centers? And then one other quick one on just, it's been a while since we've heard anything, I'm just curious if there's an update for the IBS pain study? Thank you.
Keith Katkin -- Chief Executive Officer
Sure. Appreciate the questions, Turner. So we are still exploring and having discussions with Sumitomo U.S. business here, which is Sunovion, they have a quite a large infrastructure and obviously they've demonstrated a tremendous amount of success with the sales of LATUDA exceeding $2 billion. We've talked to them so far about a host of different areas where we may be able to collaborate with them. Certainly, on drug distribution it's an important focal point for us. You probably are well aware that smaller companies, wholesalers -- with very high wholesaler service fees. We think now that we can -- that will be under the Sumitomo umbrella, we can have access to a much lower wholesale service fees which would actually save us a fair bit on gross margin.
Additionally, they've got a very large managed care footprint with a number of account managers and account executives, so we're discussing with them on how we can potentially tap into all of those relationships and also having the leverage of the full Sunovion franchise in the U.S. and we're having discussions with payers. And then they also have a number of back office commercial support capabilities as well, which we're exploring with them. And so all in all, I think to the extent the people had concerns about our ability to launch as a small company. I think the ability to tap into the Sunovion and Sumitomo infrastructure should greatly alleviate any concerns that people have about a "small company" being able to effectively commercialize as well.
In regards to your question about salesforce and salesforce expectations, we continue to expect that we'll have 100-person urology field sales force. We've already brought on a national sales director for that team. He's got tremendous experience in urology and we look forward to being able to ramp up that field sales team as we get near approval. Additionally, we'll have a 50-person long-term care sales force which we'll be able to focus in, call it, on all of the key accounts and key homes within that area. And we are having some discussions with Sunovion about, is there a potential for a co-promote. I think it's too early knowing that whether or not that's something that we could reasonably expect on anything that we would do with them, we would treat it at an arm's length transaction and it'd have to make sense for Urovant and Urovant shareholders for us to potentially to do something like that.
But then, I think your second question was in regards to the IBS pain program, that program continues to move forward with top line data expected in 2020. And so we're very much looking forward to provide continued updates on that program as we continue enrollment there.
Turner Kufe -- JPMorgan -- Analyst
Thank you.
Keith Katkin -- Chief Executive Officer
Thank you.

We have now the line of Raghuram Selvaraju from H.C. Wainwright. Your line is open.
Unidentified Participant
Good afternoon, everyone. This is Ed [Indecipherable] on for Ram. I appreciate you taking the questions. Just to go back to the Sumitomo arrangement, really on the earlier half after you've just gone through the commercialization. Just wondering if you lay out more of the spending plan for that initial $200 million and then specifically just a few points and just wondering about that $100 million Hercules Capital loan whether you'll pay that down with the $200 million, whether more funds will be devoted toward the launch or some of the clinical aspects that are still ongoing. And then wondering also if there's a roof on how much capital Sumitomo is going to commit before you guys reach profitability?
Keith Katkin -- Chief Executive Officer
I appreciate all the questions. So I think, in general, our spending plan is unchanged and as Christine said, with the $200 million loan facility, I'll expect that we'll be funded well into 2021. We are, as you'd expect, certainly evaluating whether or not we should pay down the Hercules loan, what we expect that the Sumitomo loan will be at a lower interest level, and so, it may make really good prudent sense to retire that but we will need to go through that with our Board and looking all the economics associated with that deal.
In terms of more dollars on clinical programs or commercial. We were, as always had a pretty full plan, as it related to commercial spending and clinical spending. So I don't really foresee any increase in spending on that front. But rather as Christine said, with the guidance for the remainder of this year, staying on track with that guidance.
And then finally in terms of capital on relative spends, that obviously we're still very early in the relationship with Sumitomo. So we are very appreciative that they expect to fund the company through profitability and we'll have to discuss with them as we move forward and execute on our plan exactly what that full capital commitment would look like. We obviously do want to continue with our business development efforts, we want to bring in more products and continue to grow the pipeline at Urovant. So that will be a big focus for us as well as we think of our relationship with Sumitomo.
Unidentified Participant
Thanks. And I appreciate all those details. Just a little bit on Sumitomo's strategy. What's their commitment and interest level for indications beyond OAB for vibegron? And then I've one more follow.
Keith Katkin -- Chief Executive Officer
Yeah. Certainly. So I think if you put yourselves in their shoes. They're looking at $2 billion patent cliff in 2023 when LATUDA goes generic. And so I think they've taken a very intelligent approach with a number of different shots on goal so to say with products that can fill that pipeline gap. And I think vibegron is one of the more important products that they have that could potentially fill that pipeline gap for them. So I believe that they are open to maximizing the full potential of vibegron in all possible indications. Obviously, we're all very excited about OAB. We're very excited to potentially be the first product ever approved for men that have OAB and BPH, and certainly to the extent, we saw a nice robust treatment effect in IBS pain. I think there would certainly be capital available to support that very large indication with the number of patients out there suffering from IBS-related abdominal pain.
Unidentified Participant
It makes lot of sense. And then final question, just on the long-term 52-week data, it does compare very favorably to the long-term data from mirabegron. I'm just wondering when that full data will be released and whether it's going to be in a presentation or publication form? And then when you're talking to prescribers about this long-term data, what is the degree to which they are indicating they find this long-term superiority to tolterodine more clinically meaningful?
Keith Katkin -- Chief Executive Officer
Cornelia, do you want to comment in terms of the publication plan and timing?
Cornelia Haag-Molkenteller -- Chief Medical Officer
Yeah, OK. Well, hi, this is Cornelia. So we plan to present the long-term data first at the Scientific Congress, most likely in the early second quarter of 2020 and that will be followed by a full paper publication. So there'll first be presentations, you can expect it to be in the second quarter of 2020 and then publications. And that will be the first one, Keith, do you want to take the prescriber question?
Keith Katkin -- Chief Executive Officer
Yeah. Certainly. And so, certainly, as you'd expect the healthcare providers that we've shared the long-term data with are very excited of that data. And I think as you astutely pointed out the numeric benefit of vibegron versus still tolterodine is not lost on many of them, especially when you consider the fact that with mirabegron in there one study which included tolterodine, mirabegron actually performed worse than tolterodine on a number of those endpoints throughout the 52-week period. So we think it really supports the best-in-class and potentially best-in-area efficacy profile vibegron and as I look forward to moving mirabegron through the approval process with the FDA.
Unidentified Participant
Thank you. I appreciate all the details. And I'll jump back into queue now.

Next we have Joon Lee from SunTrust. Joon Lee, your line is open.
Joon Lee -- SunTrust Robinson Humphrey -- Analyst
Hi, thanks for the question and congrats on becoming part of the Sumitomo family. As you mentioned the starting dose for mirabegron is 25-milligrams. What's the typical steady state those for mirabegron? Does that eventually end up being 50 or 75-milligrams? And how does the efficacy at a higher dose compare with 75-milligrams of vibegron? And I have a follow up. Thank you.
Keith Katkin -- Chief Executive Officer
Yeah. So if you take a look at IQVIA data in terms of what the mix of the mirabegron business is, it's about 40% to 45% of 25-milligram and the remainder being 50-milligrams. So almost half of the market there is on the lower dose and doesn't windup to addressing the higher dose or is potentially or it's potentially just swallowing off therapy because they are starting on that smaller dose and not getting the relief that they want.
And so, to the second part of your question, about comparing the mirabegron 50-milligram data with vibegron's 75-milligram data, there if you look at previous studies between mirabegron and -- we were cross study comparison to vibegron which certainly has certain limitations. You will see that the relief provided by vibegron on a numerical -- on a numeric base is actually higher than what we're seeing with vibegron -- than what we're seeing with mirabegron. And so I think that relates to the last question that was asked is looking at tolterodine as an active control and why we're so pleased that we were able to be numerically better than tolterodine at an all-time points in the 52-week [Indecipherable].
Joon Lee -- SunTrust Robinson Humphrey -- Analyst
So the patients who don't get relief from 25 or maybe 50-milligrams of mirabegron, do physicians typically explore higher dose as tolerated or -- and how many patients actually tolerate the higher dose if that is something that physicians are trying to do?
Keith Katkin -- Chief Executive Officer
Yeah, I think what our research suggest is that you would think that the communication between the patient and the physician is better than it is, but it's really not. So the patient gets the 25-milligram dose, they may end of the sample or prescription, they fill it, they wind up not getting the relief that they were hoping for either because the doctor didn't fully prepare them what to expect because they have higher hopes themselves. And then many of these patients wind up stopping mirabegron very early in the treatment cycle, and a large percentage come off within three months. And so we think that's a huge opportunity, one, to pick up those mirabegron failures and all those patients that are coming off within around three-month period, but also why start with a sub-therapeutic dose of another product that inhibits 2D6, has QT concerns and it doesn't work fast when you could have a product that works fast, doesn't have any DDi concerns and doesn't QT concerns. And so we think that the prescribing decisions going to be great easy ones, once we're -- once vibegron is out there and available for prescription.
Joon Lee -- SunTrust Robinson Humphrey -- Analyst
Great. And then I totally understand that it's just the good housekeeping to have a shelf in place, but what would be use for that $20 million in the shelf and $50 million in ATM, given that you have a low interest $20 million loan from Sumitomo? Thank you.
Keith Katkin -- Chief Executive Officer
Yeah at the current time, we just think and our audit committee believe that it's just good prudent financial planning. You never know what may happen and you may want to opportunistically take advantage of funds that are available or out there. And so last thing we would want to do is not be in a position where we could take advantage of capital markets that they were strong and our board thought that they were worth tapping into, but at current time, obviously, we're very happy with the $200 million that we've received from Sumitomo and that will just continue to monitor market conditions, stock price, things of that nature as we move forward.
Joon Lee -- SunTrust Robinson Humphrey -- Analyst
Great. Thank you and congrats.
Keith Katkin -- Chief Executive Officer

I can imagine. Yeah. And then just finally on a broader level in terms of the OAB market growth. It seems to be growing pretty strong and considering some of the details that you talked about with. If doses pan-cliff, they seem to be backing out of active promotion of Myrbetriq. So I'm wondering if you could talk about what's really driving this consistent OAB market growth. And what -- I'm sorry -- if patients are actually switching to beta 3 medications would the messaging for vibegron focus more on its differentiation versus mirabegron or there still be need to have a broader conversation around the benefits of beta 3 medications over stuff like the anticholinergics?
Keith Katkin -- Chief Executive Officer
Yeah, it's a really good question, and I think what's important to note is that as you look at the market still a large majority of the market are anticholinergics. And as we've talked about in the past, there is more and more emerging literature about the concerns of anticholinergics, their impact on cognition and certainly the increased risk of dementia from the use of those anticholinergics. So as we sit back and as we think about where the biggest market opportunity is, the biggest market opportunity is not going head-to-head with Astellas and trying to find for those patients that are going over to a beta 3. We think when they make that choice, obviously, we want to position vibegron as the best choice but we really think that the big opportunity is conversion of those patients that are on anticholinergics over to a beta 3. And so if you look at historical class situations where you've got an existing class like the anticholinergics and then a new class like the beta 3 is typically when you see a second-in-class product to come out, you see a large expansion in that class of products. So our hope is that the beta 3 class expands when we're on the market as well and that we are converting more patients from anticholinergics over to beta-3s than we are taking patients from mirabegron, and we think, quite frankly, that this represents a win-win for both us and Astellas and the [Indecipherable] patients because beta 3s are better and safer, in our opinion, than the anticholinergics for these patients suffering from OAB.
