Good morning. With me on this morning's call are Michele Greco, CFO, CAO, Michael Purvis, Executive Vice President, General Counsel, and Corporate Strategy, and Samuel Fisch, Executive Director of Investor Relations and Corporate Communications. Thank you for joining our call. Veru is dedicated to the development of novel medicines for the management of two of the most prevalent cancers, breast cancer and prostate cancer. One of our anticancer drugs, sabizabulin, has dual antiviral and anti-inflammatory effects, so it is also being developed for the potential treatment of hospitalized COVID-19 patients at high risk for acute respiratory distress syndrome, which remains a global dire unmet medical need.
The company has a commercial sexual health division called Urev, which includes two FDA-approved products, ENTADFI, a new treatment of, for BPH, which is benign prostatic hyperplasia, and the FC2 female condom, internal condom for the dual protection against unplanned pregnancy and the transmission of sexually transmitted infections. The revenue from the sexual health division is being used to largely fund the clinical development of our late-stage drug candidate assets, which aim to address multi-billion dollar premium market opportunities. This morning, we will discuss Veru's business strategy, the clinical development of our drug pipeline, and the commercialization of our products. We will also provide financial highlights for our first quarter of fiscal year 2022. COVID-19 global cases, hospitalizations, and deaths are at the highest level since the start of the pandemic. Some of the antibody drugs are not effective against the Omicron variant.
It is clear that an effective and safe oral therapeutic that prevents deaths in hospitalized patients with moderate to severe COVID-19 infection who are at high risk for acute respiratory distress syndrome is desperately needed. We strongly believe that sabizabulin, with its antiviral and anti-inflammatory properties and a favorable safety profile, can be that greatly needed oral therapy for hospitalized patients with COVID-19. Sabizabulin disrupts the intracellular transport of the coronaviruses by microtubules. This is a process that's required by all variants of COVID-19, including Omicron, to cause infection. While there have been recent developments evaluating the Merck drug, molnupiravir, and the Pfizer drug, PAXLOVID, for the treatment of unhospitalized patients with mild to moderate COVID-19 who had relatively low risk of dying, sabizabulin, in contrast, is being developed for hospitalized patients with moderate to severe COVID-19 who are at high risk of death.
Our positive phase II clinical study in hospitalized COVID-19 patients at high risk for acute respiratory distress syndrome showed that sabizabulin treatment resulted in an 82% relative reduction in deaths compared to placebo. If our phase II clinical results were replicated to any significant degree in our global phase III clinical study, we believe sabizabulin will fill a significant unmet medical need for hospitalized patients. We are conducting a phase III COVID-19 clinical study, which is a double-blind, multicenter, multinational randomized 2:1 placebo-controlled study evaluating daily oral 9-mg dose of sabizabulin for up to 21 days versus placebo in 300 hospitalized COVID-19 patients with high risk for acute respiratory distress syndrome. The primary efficacy endpoint will be the proportion of patients who die on study up to day 60.
Secondary endpoints will include the proportion of patients without respiratory failure, days in the ICU, WHO ordinal scale for clinical improvement change from baseline, days on mechanical ventilation, days in the hospital, and viral load. The study is being conducted in the U.S., Brazil, Argentina, Mexico, Colombia, and Bulgaria. In January 2022, the FDA granted Fast Track designation to the phase III COVID-19 registration program, a distinction that underscores the urgent need for new, novel, and effective therapies to be used along with vaccinations to combat this COVID-19 pandemic. The company has sufficient clinical drug supply on hand to complete the phase III clinical study and to help fund the commercial drug to supply the needs of the U.S. population, assuming confirmatory positive clinical results and FDA approval.
We're seeking funding from BARDA and other agencies. Company anticipates having the results of the phase III COVID-19 clinical trial in the first half of calendar year 2022. As for our breast cancer drug portfolio, we have an expansive metastatic breast cancer program with two of our drug candidates, enobosarm and sabizabulin. Enobosarm is an oral selective androgen receptor targeting agonist, which has shown efficacy in phase II clinical studies in a heavily pretreated hormone receptor-positive metastatic breast cancer patient population with an excellent safety profile without causing unwanted masculinizing adverse side effects. Enobosarm represents the first and novel endocrine therapeutic approach to breast cancer in decades. Our second drug candidate, sabizabulin, is an oral cytoskeleton disruptor that targets unique binding sites of cross-linked microtubules, a well-validated cancer target resulting in promising efficacy and a favorable safety profile without clinically relevant neurotoxicity, neutropenia, or alopecia.
Furthermore, chronic oral daily administration of sabizabulin is feasible. Our clinical development strategy allows us to potentially become an important treatment option for a variety of large market opportunities in hormone receptor-positive metastatic breast cancer. In the third-line treatment setting for hormone receptor-positive metastatic breast cancer, we have two clinical programs based on the patient's androgen receptor nuclear staining or expression levels in their breast cancer tissue. For patients with greater than or equal to 40% androgen receptor expression, we are actively enrolling a global phase III ARTEST registration clinical study to evaluate enobosarm monotherapy for the third-line treatment of AR-positive, ER-positive, HER2-negative metastatic breast cancer. Enobosarm targets the androgen receptor, which has tumor suppressor activity in AR-positive, ER-positive, HER2-negative metastatic breast cancer without causing the unwanted masculinizing side effects.
Enobosarm has extensive non-clinical and clinical experience, having been evaluated in 25 separate clinical studies in approximately 1,450 patients dosed, including three phase II clinical studies in advanced breast cancer involving more than 250 patients. This means we have a very good understanding of the favorable safety profile of Enobosarm. As for efficacy, there were two phase II clinical studies conducted in women with AR-positive, ER-positive, HER2-negative metastatic breast cancer, where Enobosarm demonstrated significant antitumor efficacy in a heavily pretreated cohort that developed tumor progression after receiving estrogen blocking agents, chemotherapy, and/or CDK4/6 inhibitors. Again, in this population, enobosarm was well tolerated with a favorable safety profile.
We are conducting a phase III multicenter international open label randomized one-to-one ARTEST registration clinical trial to evaluate the efficacy and safety of enobosarm monotherapy versus an active comparator of either exemestane plus or minus everolimus or a selective estrogen receptor modulator for the treatment of AR-positive, ER-positive, HER2-negative metastatic breast cancer in approximately 210 patients with greater than or equal to AR expression in their breast cancer tissue who have previously received a nonsteroidal aromatase inhibitor, fulvestrant, and a CDK4/6 inhibitor. In January of 2022, FDA granted Fast Track designation to our phase III ARTEST registration program. Fast Track designation aims to expedite the development and review of new drugs that are intended to treat serious or life-threatening conditions and demonstrate the potential to fill unmet medical needs.
Filling an unmet medical need is defined as providing a therapy where none exists or providing a therapy which may be potentially better than available therapy. In patients who are found to have less than 40% AR expression in their breast cancer tissue, we have a planned sister study, which is an open label multicenter randomized 1:1 phase II-B study evaluating the efficacy and safety of sabizabulin 32 mg monotherapy versus the active comparator of either exemestane plus or minus everolimus or SERM for the treatment of ER-positive metastatic breast cancer in approximately 200 patients who have previously received a nonsteroidal aromatase inhibitor, fulvestrant, and a CDK4/6 inhibitor. For clarity, this means we have a sister study to randomize patients that did not qualify for the phase III ARTEST study because their AR expression in the breast cancer tissue was too low.
We received the Safe to Proceed letter from FDA, and this phase II-B study is expected to commence in calendar Q1 2022. We're also moving enobosarm therapy earlier in the treatment sequence into the second-line treatment setting for AR-positive, ER-positive, HER2-negative metastatic breast cancer by targeting patients with AR-positive breast cancer expression of greater than or equal to 40% in a phase III ENABLAR-2 clinical study. A CDK4/6 inhibitor and an estrogen blocking agent combination has become the first-line therapy for patients with ER-positive, HER2-negative advanced breast cancer. Unfortunately, almost all patients will develop drug resistance and will eventually develop breast cancer progression.
Based on positive phase II clinical data and the preclinical data supporting the use of enobosarm in combination with a CDK4/6 inhibitor in patients who are CDK4/6 inhibitor and estrogen blocking agent resistant, we plan to conduct a phase III multicenter open-label randomized 1:1 active control registration clinical study named ENABLAR-2 to evaluate the efficacy and safety of enobosarm and abemaciclib combination therapy versus an alternative estrogen blocking agent in subjects with AR-positive, ER-positive HER2 metastatic breast cancer who have failed first-line therapy with palbociclib, which is a CDK4/6 inhibitor, plus an estrogen blocking agent, and who have ≥40% AR expression in the breast cancer tissue. Plans to enroll approximately 186 patients in this phase III clinical study.
We recently announced that we have entered into a clinical trial collaboration and supply agreement with Lilly for the ENABLAR-2 phase III clinical study. The terms of the non-exclusive clinical trial collaboration supply agreement. Veru is responsible for conducting the clinical trial while Lilly will supply abemaciclib for the study. Veru maintains full exclusive global rights to enobosarm. We're looking forward to our collaboration with Lilly on the ENABLAR-2 phase III clinical trial, which is expected to commence in calendar Q1 2022. We're partnered with Roche Ventana, a major global diagnostics company, to develop a companion diagnostic androgen receptor test. In the phase II ETA-1 study, we determined that the presence and the amount of the androgen receptor expression in breast cancer tissue are important for enobosarm's targeted anti-tumor activity.
In fact, we identified that patients who have greater than or equal to 40% androgen receptor staining by immunohistochemistry, which is a measure of androgen receptor expression in the breast cancer tissue, are the patients that are most likely to have an anti-cancer response to enobosarm. Based on this observation, the FDA recommended that we develop a companion diagnostic test to determine the patient's AR expression status. Consequently, we have partnered with Roche Tissue Diagnostics, world leader in oncology companion diagnostic tests, who are developing and have approved plans to commercialize the companion diagnostic androgen receptor test. The companion diagnostic test is being developed in parallel with the phase III ARTEST clinical study.
Although the company has been planning to commence a single-arm sabizabulin plus enobosarm combination for metastatic triple-negative breast cancer patients in a phase II clinical study that was supposed to start early in this calendar year, we have now decided to focus our finite resources on more advanced pipeline opportunities and suspend work on this trial. Nevertheless, the company remains committed to advancing triple-negative breast cancer study in the future. As you can see, we have developed an important and deep breast cancer program dedicated to developing late clinical stage studies addressing three separate indications. The first indication is evaluating sabizabulin, the third-line treatment of metastatic castration-resistant prostate cancer in the phase III VERACITY study. Several novel androgen receptor-targeted enzalutamide and apalutamide.
Unfortunately, most men with metastatic castration-resistant prostate cancer will develop tumor progression while receiving an androgen receptor-targeted agent, with 60%-70% of patients progressing by 12-18 months, and 30%-40% of men having no benefit at all. New, effective, and well-tolerated treatment alternatives that do not target the androgen receptor axis and that have an easy mode of administration are greatly needed. Sabizabulin is a member of a novel class of drugs that disrupts the cytoskeleton by targeting unique binding sites on microtubules, which results in an improved safety profile. In preclinical models, there was no evidence of significant liver toxicity, neurotoxicity, and neutropenia with sabizabulin treatment. This more tolerable safety profile has also been confirmed in a first-in-man phase I-B/II study in metastatic castration-resistant prostate cancer patients.
We will be presenting updated clinical data from the positive phase I-B/II study of sabizabulin in 80 men with metastatic castration-resistant prostate cancer who have progressed on at least one novel androgen receptor targeting agent at the ASCO Genitourinary Cancers Symposium being held February 17-19 in San Francisco, California. We are conducting an open-label 2:1 multicenter phase III VERACITY clinical study evaluating sabizabulin 32 milligrams versus an alternative androgen receptor-targeted agent for the treatment of chemotherapy-naive men with metastatic castration-resistant prostate cancer who had tumor progression after previously receiving at least one androgen receptor-targeted agent. Primary endpoint is radiographic progression-free survival. Enrollment for the phase III VERACITY clinical study is on track, and we expect to enroll approximately 245 patients from 45 clinical centers in the U.S.
Clinical study is evaluating VERU-100, a GnRH antagonist, a three-month depot formulation in a phase II dose-finding clinical study for the treatment of hormone-sensitive advanced prostate cancer. Deprivation therapy remains the mainstay primary therapy for advanced prostate cancer. The current androgen deprivation therapy drug products have several important clinical shortfalls. LHRH agonist initial administration leads to a testosterone surge that can last up to 21 days. Firmagon, a GnRH antagonist, is a large volume subcutaneous injection formulation designed for only a single-month release. Relugolix is an oral GnRH antagonist that has the potential for poor patient compliance. In contrast, VERU-100 has a target product profile that addresses a number of these important clinical shortfalls of the currently commercially available androgen deprivation therapy products. VERU-100 is a long-acting GnRH antagonist designed to be administered as a small volume subcutaneous three-month depot injection.
VERU-100 drug product is expected to immediately suppress testosterone with no testosterone surge. VERU-100 as a long-acting injected depot would ensure patient compliance while on treatment. Furthermore, as a class, GnRH antagonists have been shown to have fewer cardiovascular adverse events than LHRH agonists. We're conducting a phase II dose-finding clinical study of VERU-100 androgen deprivation therapy in 35 men with hormone-sensitive advanced prostate cancer. Although this study is ongoing, the preliminary clinical data are promising. The phase III registration clinical study design has already been agreed upon with FDA. It will be a single-arm study which will enroll approximately 100 men. Maintenance of castrate blood concentrations of testosterone is the primary endpoint. After the phase II dose-finding study is completed, we will initiate the phase III clinical study, which is anticipated to begin in calendar second half of 2022.
In our third late-stage clinical study, we plan to advance zuclomiphene for the treatment of hot flashes caused by androgen deprivation therapy in a planned phase II-B clinical study later in the calendar year 2022. In summary, we'll have three late-stage clinical studies for the management of advanced prostate cancer in calendar year 2022. Now, Veru has a commercial sexual health division called Urev, which includes two FDA-approved products, FC2 for the dual protection against pregnancy and STIs across the U.S. As a result, FC2 is now available through multiple sales channels. In particular, we have partnered with fast-growing, highly reputable telemedicine platform companies to bring our FC2 product to patients in a cost-effective and highly convenient manner. Sales is not only to seek additional telemedicine and internet pharmacy service partners, but also to create our own dedicated.
Has been shown to be more effective for the treatment of benign prostatic hyperplasia than finasteride alone without causing impotence. ENTADFI was approved by FDA in December 2021, and commercialization plans are now underway. The plan is to officially launch ENTADFI next quarter. ENTADFI is expected to be marketed and distributed also by our own direct-to-patient telemedicine and internet pharmacy services platform. We have also partnered with GoodRx, a U.S.-based digital resource for healthcare, to reach their almost 20 million monthly visitors, which include both consumer and healthcare providers, to build awareness to send patients to our telemedicine platform and to convert existing men on BPH treatments, those treatments that cause sexual side effects, to ENTADFI. There are over 45 million prescriptions filled annually for drugs to treat BPH.
We plan to augment our marketing and sales efforts by seeking additional partners in the U.S. and ex-U.S. I will now turn the call over to Michele Greco, the CFO and COO, to discuss the financial highlights. Michele.
Thank you, Dr. Steiner. As Dr. Steiner indicated, the company has a number of significant clinical trials and processes. Let's review the first quarter results. Net revenues were $14.1 million compared to $14.6 million in the prior year quarter. The prior year quarter included net revenues of $863,000 related to PREBOOST, which the company sold on December 8, 2020. The company reported FC2 sales growth in its U.S. prescription business, with net revenues up 27% to $11.6 million from $9.1 million in the prior year quarter. Net revenues for the public sector business were $2.6 million compared to $4.7 million in the prior year quarter. The prior year quarter included revenues related to the Brazil and South African tenders.
Overall, gross profit was $11.8 million or 84% of net revenues compared to $10.8 million or 74% of net revenues in the prior year quarter. The increase in gross profit and gross margin is driven primarily by increased sales in our U.S. FC2 prescription business. This quarter's 84% gross margin is the highest in the company's history. Operating expenses for the quarter increased to $16.8 million compared to the prior year quarter of $10.1 million.
The increase is primarily driven by research and development costs, which increased to $10.1 million from $5.7 million in the prior year quarter, and increases in personnel and related costs to prepare to commercialize ENTADFI. During the prior year quarter, the company sold PREBOOST for $20 million, $15 million in cash, and $5 million in notes receivable due in two installments over an 18-month period. The sale of PREBOOST resulted in an $18.4 million pre-tax gain. The operating loss for the quarter was $5 million compared to operating income of $19.2 million in the prior year quarter. This change is primarily due to the gain on sale of PREBOOST of $18.4 million, plus the increase in research and development costs of $4.4 million.
Non-operating expenses were $1.3 million compared to $1.9 million in the prior year quarter, and primarily consisted of interest expense and change in the fair value of the derivative liabilities related to the synthetic royalty financing. We entered the synthetic royalty financing during March of 2018. For the quarter, we recorded a tax expense of $115,000 compared to $78,000 in the prior year quarter. The bottom line results for the quarter was a net loss of $6.4 million or $0.08 per diluted common share, compared to net income of $17.2 million or $0.23 per diluted common share in the prior year quarter.
The company has net operating loss carryforwards for U.S. federal tax purposes of $38.6 million, with $29.5 million expiring in years through 2040 and $9.1 million, which can be carried forward indefinitely. Our U.K. subsidiary has net operating loss carryforwards of $63.5 million, which do not expire. Now looking at the balance sheet. As of December 31st, 2021, our cash balance was $116.1 million. Our accounts receivable balance was $8.1 million, and our notes receivable related to the sale of PREBOOST were $2.5 million. Our net working capital was $131.8 million at December 31, 2020, compared to $136 million at September 30, 2021.
Overall, we're delighted to see the growth in the U.S. FC2 prescription business and look forward to increasing sales in the global public sector business. This revenue source, together with our strong balance sheet, continues to be the source of funds we use to invest in our promising pharmaceutical clinical development programs as we continue to transform our company into a premium oncology biopharmaceutical company seeking large market opportunities in breast and prostate cancers, as well as being opportunistic by joining the global efforts to find effective treatments for COVID-19. Now I'd like to turn the call back to Dr. Steiner.
Thank you, Michele. In summary, we've had a highly productive financial first quarter, which has allowed us to significantly advance our clinical oncology programs. We've organized our FDA-approved products into a sexual health division called Urev. We're now entering our sixth year of growth in our FC2 U.S. prescription business. We're executing on a solid plan to expand partnerships and to launch our own direct-to-patient telemedicine and internet pharmacy services portal. We plan to commercially launch ENTADFI, also via our own direct-to-patient telemedicine and international services portal, and we have partnered with GoodRx to drive awareness and prescription conversion. Both programs should allow us to continue the robust growth of revenue from the Urev sexual health division. Having these resources in place will allow us to continue to advance our deep late clinical stage breast cancer and prostate cancer programs, as well as a phase III COVID-19 clinical study.
We are quite pleased to have recently received Fast Track designations from FDA on two of the company's major drug development programs this past month. We anticipate a steady flow of important positive news for Veru over the next few months to one year. We're committed to driving shareholder value by developing and commercializing novel medicines, addressing significant unmet medical needs for the management of breast cancer and prostate cancer, and being opportunistic by developing sabizabulin for hospitalized COVID-19 patients and high risk for acute respiratory distress syndrome and death. With that, I'll now open the call to questions. Operator?
Thank you. Ladies and gentlemen, at this time, we will begin the question and answer session. To ask a question, you may press star then one on your telephone keypad. If you're using a speakerphone, we ask that you please pick up your handset before pressing the keys to ensure that the best sound quality. To withdraw your question, please press star then two. Please limit yourself to one question and one follow-up. If you have further questions, you may reenter the question queue. Once again, that is star then one to join the question queue. The first question today comes from Brandon Folkes with Cantor Fitzgerald. Please go ahead.
All right. Thanks for taking my questions, and congratulations on all the progress. Maybe just first on the COVID program, just given that's a near-term catalyst, how do you view the bar having shifted or not on the COVID endpoints, especially around mortality? Along those lines, do you think that the secondary endpoints alone could support an approval here?
Just say the first part about mortality again. What about the primary endpoint?
Do you think that agencies have shifted their view on endpoints, right? If we're not successful on mortality, do you think these secondary endpoints alone could still support an approval from the regulatory agencies?
Yeah. Got you. The answer is, I don't think they're switching at all on the primary endpoint. I think that if you've seen some recent activity and some people reporting results and they're reporting results now on their primary endpoint. At the beginning of any clinical trial, you state your primary endpoint. I'm not saying this to you, but I'm just saying this for the people listening on the phone. You have to, you know, hit your primary endpoint. I mean, that's what defines success in a trial. Mortality, you know, death, I mean, that's about the hardest endpoint you can get. You can't fake a death. Death is what we're trying to deal with in something as horrible as the pandemic.
With that said, no, I do not think agencies are shifting on their desire to see an impact in mortality. I think we're good there. However, having said that, let me just make one more comment. The other comment is. Well, no, let me make this next comment, then I'll make the one I was about to make. To answer your question, there are key secondary endpoints that, if you miss on mortality, and you hit these other ones, there could, you know, there could be a discussion with FDA that these could stand on their own, but that's a discussion with FDA.
Now, one thing that gives us comfort is, as you know, the space has gotten so crowded in pre-hospitalized patients, so patients that are not in the hospital, it's no longer an unmet medical need. You've got the Pfizer drug, the Merck drug, and others. In the hospitalized setting, what we're learning now is the drug. In fact, the FDA has even said that, with the Omicron variant, that some of these antibody drugs that are currently out there for people in a hospitalized setting should not be used. The fact that we got Fast Track designation by FDA for hospitalized patients means it's still an unmet medical need.
In the event that you have an unmet medical need and you have a secondary endpoint that's successful, and you don't hit on mortality, that's a little different than the other options out there. In that setting, I think we have a lot of room to talk to FDA with the key secondary endpoints, if that's what you hit in a setting of an unmet medical need. Again, the unmet medical need is not what we're saying. It's the fact that we just got FDA Fast Track designation means that they also. Because remember, they see drugs in development, and they see drugs that are approved. You know, that gives us some comfort. We continue to work in a very important area of unmet medical need.
Great. Thank you very much.
Thank you.
The next question comes from Leland Gershell with Oppenheimer. Please go ahead.
Hey, good morning. Thank you for taking my questions. Wanted to ask Mitch with respect to your development in breast cancer, being that the androgen receptor is, you know, appears to be a tumor suppressor in breast cancer, wanted to know, you know, as you divide between those with AR expression above 40% and below 40%, you know, how that breaks down with respect to the size of the fractions of the population with breast cancer with those levels of AR expression. Would the thinking be correct that more advanced ER-positive HER2-negative breast cancer would be more enriched in the AR, given that those tumors are likely more resistant to therapy, given their expression of AR?
I also want to ask with respect to Urev, to the extent your market research may indicate, what potential peak revenue might we expect for that product? Given that you're selling that through the telemedicine channels, you know, your own that you're setting up and others, kind of give us a sense of what your margins may be on that product. Thank you.
The first question basically is trying to understand the patient population of AR positivity. The way to look at it is that, and I had made this comment before, that, you know, men and women are born with the same machinery to make breast tissue. Why is it that, women develop breast tissue and men do not? The answer is the same machinery means there's an estrogen receptor and there is an androgen receptor. In women, estrogen and no androgens develops breasts. In men, androgens and no estrogen, you don't get breasts. It's a tremendous tumor suppressor. It's a tremendous suppressor of growth. It's not surprising that up to 90% of breast cancer tissue will have an androgen receptor expression.
Now the question becomes, and the question you're asking is the enrichment part. In other words, greater than 40%, less than 40%. When you look at the numbers, and this is based on our phase II, so about 85% of breast cancers are gonna be ER-positive. Of those 85% that are ER-positive, about half of those will be AR-positive, greater than 40%. That's, so it's still a huge market and pretty prevalent target that we can have an opportunity to hit. 50% would be AR less than 40%, and roughly 50% would be AR-positive greater than 40%.
That's the reason why we have the sabizabulin trial and the Sister trial, because we know when we go out there and start looking for patients with metastatic AR-positive breast cancer, that half of them, roughly half of them, are gonna be candidates for enobosarm. We've got another active agent in breast cancer, so why not, why not, allow that patient to have the choice of door number one or door number two. Door number one, if your androgen receptor is greater than 40% expression, you get to go on enobosarm. If you're less than 40%, you get to go on sabizabulin. We get a, you know, two bites of the apple there. Both of them are huge markets, so demographics are in our favor.
Interestingly, we did see an independent presentation at the San Antonio Breast Cancer Symposium this past December that showed, and maybe this explains why the combination of a CDK4/6 inhibitor with enobosarm could be interesting, because it turns out that this is not static, it's pretty dynamic. Meaning the androgen receptor expression can change, and it can change with the actual treatment that you're getting. What the San Antonio study showed is that one, maybe one of the reasons why the combination of a CDK4/6 inhibitor and enobosarm makes sense is it turns out that the CDK4/6 inhibitor actually induces the upregulation or the expression of androgen receptor on breast cancer tissue.
Another way of saying it is, if enobosarm is trying to look for the androgen receptor and the CDK4/6 inhibitor makes more androgen receptor, that may explain the potential synergy between the two. It's not just what's there, 50/50, but it could be that there's a bigger population to go after because a CDK4/6 inhibitor will take somebody out of the 40% range and put them higher. That's for another day. As it relates to ENTADFI, we have not given guidance except to say that one. I mean, we think we're on some incredibly sure footing for a couple of reasons, okay? One, there really hasn't been a new BPH drug in many, many years. You know, we would be the first new BPH drug.
As you know, all the BPH products have some sort of sexual side effect. Finasteride in particular, which is very, very popular, which shrinks the prostate, it one of the number one side effects it has, and one of the number one sexual side effects it has, is impotence. By combining finasteride with tadalafil, ENTADFI now becomes. It's not just a new BPH medicine, it is a, they call it new chemical entity in the sense that it's not substitutable. You can't substitute it. It stands on its own, which means it's branded. We have a branded product that could have a branded price, will be viewed as branded through the, by insurance companies, including Medicare.
Our pricing will be comparable to a branded product in the BPH space. The fact that we don't have those sexual side effects of impotence in the combination compared to finasteride alone really gives us an opportunity to convert, you know, established patients who are having problems. That's a low-hanging fruit to us. Now to put this in perspective, the sales, I mean, the most recent IQVIA data that I've seen, you know, this is still about a billion-dollar market with 45 million prescriptions. If you can convert, you know, 1% or 2% of those patients into a branded price, you're already starting to hit numbers that are well above $200 million.
That's with 1%-2% of the total market being converted to a branded product. We think, you know, there's real upside here, but we have not given any guidance. We just believe it's a big market, that we have a differentiated product, that it's a branded price, and we're gonna be taking advantage of telemedicine. Not only telemedicine, but we're gonna take advantage of GoodRx incredible breadth of being able to go out there and, I mean, GoodRx spends about $300-$400 million a year bringing people to their website. It's not just consumers, it's also healthcare providers.
To be able to drive awareness and to focus primarily digital, I lack of a better term, digital advertising to those patients that are most in need so you're efficient with your resources gives a real option. Can we hit 1% or 2%? Can we hit 3%? Can we hit 4%? It feels doable. This could be a very important product to help us continue to drive the robust revenue that we're seeing from Urev. By putting ENTADFI in with FC2, the two FDA-approved products just ensures that we can continue to maintain and largely pay for the clinical development of our products.
Do that particularly in an environment where, you know, you know, biotech looks like it's having a rough spell, but if you can look at our numbers and look at what we have in the bank, it looks like this model's working. We can, if we can adjust how we, what revenues come in, which is significant with our development program, it puts us on sure footing that our shareholders will see, you know, these multi-billion dollar opportunity products, without seeing, you know, big dilution that typically happens in biotech companies that are constantly raising money every six months to 12 months.
Great. Thank you.
The next question comes from Chris Howerton with Jefferies. Please go ahead.
Hi, good morning, and thanks for taking the questions. Really appreciate all the progress in the call this morning, Mitch. Maybe just two questions from me. One would be, could we get a little more color around the strategic decision to no longer pursue triple-negative breast cancer? Was just competition in terms of like TRODELVY and other options make that less commercially viable at this point? I guess, you know, what is some of the other thinking around pausing that program? The second one would be abemaciclib, you know, could you just give us some thoughts around the market share and why that's the right partner for enobosarm and what that might mean for the commercial opportunity in let's say second-line HER2-positive. So, thanks.
Yeah. Two very, very good questions. Okay, let's start with the first one. The first one is purely a prioritization decision. We still believe that triple-negative breast cancer is a major market. If you look at TRODELVY, and you know they developed a compound for patients with metastatic triple-negative breast cancer that had failed two systemic chemotherapies, and that drug got bought by Gilead for $24 billion. There's a market there, and you know we have two oral therapies, enobosarm and sabizabulin, and we don't see, you know, the neutropenia and all the other stuff and the black box stuff that you see with TRODELVY. We think there's a real opportunity. We had to make a financial decision.
The financial decision was that, as I mentioned in the previous question answer, is I don't know what's happening out there in the biotech space. I think a lot of companies are gonna be in trouble if they think the markets are wide open for them to raise money. Our thinking is we've got money in the bank, so that is the real reason why we need to be prudent with our resources and prioritize our resources because it, you know, it's one thing to have no money in the bank and prioritize, and another thing to have money in the bank and prioritize. If you look at our burn rate, quote, the cash we use, it's small, okay? Why is it small? Because we've offset it with revenue coming from our sexual health business.
In order to make sure, until I see the things open up, then, you know, we've got a lot going on. We've got three or four phase IIIs, and we've got a phase II-B, and you've got the other ones that soon can be a phase III. We said, "You know what? Let's pause on the triple-negative breast cancer program," and that will put our spend on clinical development pretty much matching what we think will be coming in with our revenue from the Urev business, so that we can wake up with significant resources in the bank at the end of the year.
If it looks like, you know, it looks like we have more revenue coming in because of the TASB, then we can make, you know, further decisions to move another trial forward. We're blessed in that we have, you know, new chemical entities that we own as a company that can and will have promise. I think no one will get mad at us for seeing through some of these phase III programs, 'cause it'll put us in a different market cap and also different financial setting, so then we can move still other programs. It's purely a prioritization play. It has nothing to do with the market.
I think the market is huge opportunity, but we're dealing with a lot of huge opportunities, and we just had to prioritize. As it relates to your second question on abemaciclib, here's a very interesting point and why we thought Lilly made sense as a partner. It turns out that. When we first got involved with breast cancer, people kept saying, "Oh, the field is crowded. You're not gonna be able to differentiate yourself." Of course, that's not true because the androgen receptors were completely unexploited. We thought by coming in with the androgen receptors with enobosarm, the first druggable, real, druggable selective androgen receptor targeting antagonist, that we had something that was new. What changed the landscape was the CDK4/6 inhibitor.
People on the call, CDK4/6 inhibitor changed the landscape because it became the standard of care in first-line breast cancer treatment if you are ER-positive, HER2-negative. That's the largest population of breast cancer patients. The company that owns that space right now is actually Pfizer because abemaciclib, excuse me, palbociclib in combination with an estrogen-blocking agent is being used 80% of the time. 80% of the time, which means the other 20% is being fought over by Novartis' ribociclib and Lilly's abemaciclib, okay? Unfortunately, as a matter of fact, the fortunate part is women will see between 24 and 31 months of progression-free survival, which is unbelievable, but they overall unfortunately progress.
When they progress, there's really nothing approved and nothing in the NCCN guidelines that follows the CDK4/6 inhibitor. This space is wide open. It makes sense to go into second line with an agent that has shown in preclinical models that the combination of enobosarm plus a CDK4/6 inhibitor has synergy. That synergy is probably related to the fact that the CDK4/6 inhibitor is increasing the androgen receptor, making enobosarm work better. It's not just adding two drugs together to see an additive effect, but it could really be a significant synergistic effect. If that's the case, you need a CDK4/6 inhibitor. What's a better situation to get a CDK4/6 inhibitor that is not being used in that 80% of patients in first line?
That means if 80% of patients in first line are using palbociclib, they need a new one. That new one could be abemaciclib. We're really positioning enobosarm. I hope to grab that 80% of patients that fail palbociclib plus an estrogen blocking agent by now. Now they're gonna be looking for something else, and maybe that something else will be abemaciclib and enobosarm. It was very strategic to partner with Lilly on this one because their agent, which is a very good agent, and they came later to the game, could be, you know, could be in combination with enobosarm, the go-to combination after patients have failed first line.
That makes a lot of sense, and I really appreciate it. Thank you, Mitch.
Thank you.
The next question comes from Yi Chen with H.C. Wainwright. Please go ahead.
Thank you for taking my questions. My first question is, could you tell us whether the enrollment speed for the ARTEST study and the VERACITY study is meeting your expectation?
Yes. To answer your first question, the ARTEST and the VERACITY studies, both of them, are enrolling on track.
Got it. Thanks. Could you tell us what's your current expectation for revenue from ENTADFI for this fiscal year?
Yeah. Thank you for the question. I answered. Somebody else, I think Leland, also asked that same question. We have not given guidance as to what we think the revenue will be. What we have said is a couple things. We've said that there are 45 million prescriptions filled each year with BPH. We know that almost all BPH products are gonna cause some sort of sexual dysfunction. We know that the finasteride products have impotence. We know the combination of finasteride and tadalafil, which is ENTADFI, does not. We do not see the impotence. We think there's a real opportunity to convert these patients to the combination therapy ENTADFI.
We also said that the BPH market looks like it's about $1 billion and about 2%-3% of that's branded products, which make up about, you know, $300 million-$400 million of that $1 billion. If we were able to convert 1%-2% of that market towards ENTADFI, it could be big.
Okay. Regarding the triple negative breast cancer program, do you think there's a chance you might reactivate the program in the future? How soon may that happen?
Yeah. As it relates to commitment and reactivating it, the answer is absolutely we're committed to reactivating it. It's purely a timing and prioritization of resources under the current, you know, market conditions and the fact that we have so many phase IIIs going on, with particularly COVID-19, that we felt that, you know, for an organization our size, that we probably should pause on that, not spend that money, and keep our money spent, very close to our revenue, or not just revenue, the cash coming off the sexual health business so that we can, you know, go another year with, you know, with impressive money in the bank. That was the thinking. You know, things can change.
If COVID-19 hits and or if you know we find ourselves in a situation that Urev and FC2 continue to generate 30%-40% growth you know year after year, we're going into our sixth year and we see something like that, then it'll be pretty easy. I mean, the protocol is written. You know, it's ready to go. We have the drugs, it's ready to go. So we can pretty quickly get it back on track. This is purely a prioritization of resources to keep our spend within our cash coming off the revenue-based business as much as possible.
Got it. Lastly, are there any parties that are interested in purchasing the Urev sexual health division from Veru?
The answer is, are there any parties interested in purchasing it? The answer is yeah, there are parties interested in purchasing it. The real question for us is making sure that it's the right value for our shareholders and to make sure that we take advantage of you know. I mean, right now it's generating a lot of money for us, and it feels good to have that revenue base right now. We think there are things that we can do to make the sexual health division look even more attractive so that we can, you know, look even more valuable. That is by now going from a women's health company to a sexual health company. Instead of having a single product, now we have two products.
Instead of using other telemedicine partners, we're gonna become a telemedicine entity ourselves. All of those things will add more value to the base business. While we're enjoying the cash flow coming from the base business, at the same time we're also increasing the value of the base business so that when we're ready, we'll have, you know, some more opportunities, more options, to monetize.
Great. Thank you.
The next question comes from Kumar Raja with Brookline Capital Markets. Please go ahead.
For taking my questions, and also congratulations on all the progress. First, with regard to COVID-19 patients, what are you seeing there? Is it fair to estimate that you are close to completion of enrollment given that you're planning to release data in the first half?
Make sure the question. It's a COVID-19 study and the question is, say it one more. It's my phone breaking in and out, so I apologize.
In terms of hospitalization, what kind of trends are you seeing?
In terms of hospitalizations.
Given that you are planning data in the first half, is it fair to expect that you are close to completion of enrollment?
I hear what you're saying. Yeah. The good news is that we're on track, you know, to as I said in my formal comments, we're on track to have data, clinical trial results for the study, in the first half of this year. I will tell you that, you know, the hospitalizations have increased tremendously across the world, unfortunately, for the patients, 'cause we don't, you know, of course, we don't want to see that, but that's what's happening. As you know, hospitalizations and death lag behind new cases.
What's interesting is what we're seeing is that the cases that make it to the hospital and, you know, you know, those ICU-type patients, you know, once they're on that slippery slope, we're finding that it's the death rates in patients that are at risk, especially those at risk for acute respiratory distress syndrome, is similar to the other variants. It's just that the milder stuff, you know, you know, you see a lot of it, but the ones that finally make it to the hospital is a problem. If you know, there's about 140,000 new hospitalizations a week, and so I mean, it's the highest ever in the pandemic. It's higher than all the other three waves.
With that said, it's put us in solid footing to enroll and to get the data in the first half of the year. All I'm gonna tell you is that, you know, we believe that we will have clinical data in the first half of the year to in-patients who are hospitalized, which, as you know now, there's no medicine available. The Fast Track status from the FDA is further confirmation that it's an unmet medical need. If we can fill that unmet medical need with an oral agent that's not an infusion, that doesn't require cold storage, so that you can, you know, put it in backpacks and get it to remote areas of the world.
It's hospital-based as opposed to pharmacy-based so that you can quickly get it, you know, mobilized into hospitals as opposed to trying to get it to every pharmacy, you know, in the country. From a distribution standpoint, you know, it would be a lot easier. I think we're kind of in the right space, right time and we're on track to provide data in the first half of this year.
Okay. With regard to enobosarm and sabizabulin, what kind of interactions have you had with EMA? Can the ongoing trials be leveraged for approval in ?
As it relates to the EMA, you know, all our interactions have been with FDA. Our interactions with EMA for the international studies have been to make sure that we file the appropriate paperwork so that we can do the studies in Europe, which we have. But we have not gone to EMA to seek scientific advice or anything of that sort, mainly because, you know, our studies are pretty straightforward. But we will, as we get the enrollment going and yeah, we'll go back to EMA and go back to Japan.
At this point now, you know, our thinking is focus in the U.S., and when we partner the opportunity, the partner will have the wherewithal and the ability to do Japan and Europe at the same time. You know, we're successful in the U.S., which is the premium market, we'll be in good shape.
Okay. Finally, with regard to COVID-19 external funding, is the funding mostly for manufacturing?
Yes, as you know, we're essentially almost done with the clinical study. Where we're gonna need the most help is gonna be in procurement and distribution. Merck got I don't know, I can't remember the number, but it was a big number, a billion-something, and Pfizer got a billion-something for procurement. It's no risk to the government once you get an EUA, an emergency use authorization, then the issue becomes, the government needs to buy it and get it out there. If we're successful in our phase III and we have an EUA, we feel pretty strongly and we believe that we should be able to get external funding to help us with scale-up and distribution.
That's been our focus. Interestingly, after the wave of vaccines and antibody drugs, you know, BARDA has just gone silent in terms of funding of these opportunities. They're very, very active once you've shown efficacy and safety. We're gonna take advantage of that window.
Thanks so much.
Thank you.
