Thank you, Robert. Thank you everyone for joining the call today. We're really excited to update you on the significant progress made during the Second Fiscal Quarter to advance our three clinical programs. We remain on track to initiate and enroll the first patient in our phase III safety study for GTX-104 in the H1 of calendar 2023. This is a key milestone for the company and what is expected to be the final clinical step required to seek regulatory approval. As a reminder, GTX-104 is our most advanced clinical program focused on developing and commercializing a novel aqueous formulation of Nimodipine for continuous IV infusion to treat patients suffering from subarachnoid hemorrhage or SAH. I'll go into more details in a moment on upcoming timelines and the overall business opportunity for this program.
Also, during the Second Fiscal Quarter, we initiated two PK bridging studies, one for GTX-102, our novel concentrated oral mucosal spray of betamethasone intended to improve the neurodegenerative symptoms of Ataxia-telangiectasia, or AT, in pediatric patients. One for GTX-101, our non-narcotic topical bioadhesive film-forming bupivacaine spray designed to treat postherpetic neuralgia or PHN, the severe and often debilitating nerve pain that can persist following a shingles infection caused by the varicella-zoster virus, the same virus that causes chickenpox. The GTX-102 PK study is expected to be completed with top-line results reported before year-end. With positive results from this study, we expect to initiate our phase III program in children with AT in the H2 of calendar 2023.
The GTX-101 single dose PK study is also expected to be completed by the end of calendar 2022 and is expected to provide important information on the dosing strength and frequency ahead of the initiation of additional clinical studies of GTX-101 in humans planned next year. I'll dive deeper into planned activities and the overall opportunities for both GTX-102 and GTX-101 in a moment. Perhaps most important in today's environment is that we finished the second fiscal quarter ending September 30th, 2022, with about $35 million in cash equivalents, and short-term investments. Based on current projections, we believe this is sufficient capital to continue to fund operations through at least March of 2024, and will fund the advancement of GTX-104 well into phase III and allow us to advance GTX-102 and GTX-101 to additional key inflection points.
Taking a step back, as a reminder, our strategy is to leverage the company's drug delivery technologies and capabilities to reformulate and repurpose marketed drugs for new orphan indications where a significant unmet medical need exists. The well-understood efficacy and safety profiles of these marketed compounds provide the opportunity for us to utilize the FDA's Section 505(b)(2) regulatory pathway for the development of our reformulated drug candidates, and therefore may potentially provide a shorter, less risky, and less costly path to regulatory approval. For those not familiar, under Section 505(b)(2), if sufficient support of a product's safety and efficacy can be established, either through previous FDA experience or sufficiently within the scientific literature, it may eliminate the need to conduct some of the preclinical and clinical studies that new drug candidates might otherwise require under the 505(b)(1) pathway.
I've mentioned before, all three of our drug candidates have already received Orphan Drug Designation from the FDA and have the potential to be considered for Fast Track and approval. Orphan Drug Designation provides for seven years of marketing exclusivity in the United States post-launch, provided certain conditions are met, and 10 years in Europe. These rare diseases also typically involve clinical trials with fewer patients and provide market opportunities that often require a much smaller, more targeted commercial infrastructure. It's important to point out that the orphan diseases that Acasti has targeted for drug development are well understood, although these patient populations may remain poorly served by any available therapies. For example, in the case of our GTX-102 for children with AT, approved drug therapies do not yet exist.
Our aim is to effectively treat the debilitating symptoms that result from these underlying diseases, with the ultimate goal of improving quality of life and outcomes for these patients and their families. We believe that leveraging the Section 505(b)(2) regulatory pathway for the development of our reformulated versions of these drugs provides us with highly attractive opportunities in orphan disease indications with little or no current competition. Okay, let me now circle back to GTX-104, and I'll update you on the upcoming timelines, milestones, and what we see as the overall commercial opportunity. As I mentioned, GTX-104 is a novel formulation of Nimodipine for IV infusion designed specifically for patients with subarachnoid hemorrhage or SAH, which is a condition caused by bleeding on the brain due to a ruptured aneurysm.
SAH presents a life-threatening emergency for the patient, and our new proprietary IV drug formulation addresses a vital need in the critical care market that has seen little innovation in over 30 years. The condition of SAH patients is so critical that 10%-15% of them die before they ever reach the hospital, and only about 1/3 ultimately survive. Another third of these patients require dependent care for the rest of their lives. To help address this very severe condition, we completed a phase I PK bridging study in May of 2022, which successfully met all of its endpoints. The primary objective of the study was to evaluate the relative bioavailability of our IV GTX-104 compared to oral Nimodipine capsules in healthy adult male and female subjects, while the secondary objective was to assess its safety and tolerability.
Importantly, the inter- and intra-subject variability was much lower for GTX-104 as compared with oral Nimodipine. We believe that because of its better absorption profile and more consistent blood levels, GTX-104 may provide physicians with a more reliable and effective treatment for patients with SAH. This could be a key advantage as GTX-104 could help to reduce the incidence of hypotensive events and vasospasm, which require immediate and costly intervention, such as balloon angioplasty or the use of intra-arterial vasopressors, which can lead to a worse outcome for the patient. We've submitted a letter to the FDA to request a Type C meeting to review and discuss the results of the PK bridging study and our proposed design for the phase III safety study, as we believe it's important to obtain the FDA's feedback and guidance before initiating the phase III safety study next year.
We expect to meet with the FDA by early January 2023, which should allow us to initiate the phase III safety study and enroll the first patient according to plan in the H1 of 2023. As mentioned, the phase III safety study is expected to be the final step required to seek regulatory approval before submitting a New Drug Application to the FDA for GTX-104 for the treatment of SAH patients. We're extremely excited about the opportunity to bring a new treatment option to patients that suffer from SAH with an estimated 50,000 patients per year in the United States alone. Based on our market research, we believe that GTX-104 represents a total available market in the U.S. of more than $300 million.
The current standard of care is an orally administered drug called Nimodipine, which was approved by the FDA way back in 1988. Nimodipine is a potent calcium channel blocker that relaxes the blood vessels in the brain and lowers blood pressure to allow more oxygenated blood into the brain to enhance healing. It's typically given throughout the entire period that the patient remains in the hospital, which can be up to three-four weeks or sometimes even longer, depending on the severity of the patient's condition. Nimodipine is available in the U.S. as an orally administered capsule or liquid, which is problematic as many of these SAH patients are not conscious, or if they're awake, they have a hard time swallowing oral drugs.
Consequently, Nimodipine often must be delivered via a nasogastric tube, and the drug can stick to the inside of the tube, which can result in significant variability in dosing. Oral Nimodipine is also poorly absorbed, adding to the difficulty in controlling the blood pressure of the patient. For these reasons, physicians sometimes must reduce the dose or discontinue Nimodipine altogether, meaning the patient will not get the full benefit of the drug. We believe that GTX-104 delivered intravenously could be a game-changer as a more convenient, efficient, and precise way to deliver Nimodipine directly into the patient's bloodstream. Okay, let's transition now to GTX-102, and I'll start with a brief program overview. GTX-102 is a novel, concentrated oral mucosal spray of Betamethasone intended to improve the neurological symptoms of Ataxia Telangiectasia or AT, for which there are currently no FDA-approved therapies.
AT is a progressive genetic neurodegenerative disorder that primarily affects young children, causing severe disability, impairment of the immune system, and an increasing susceptibility to infections and cancers. Patients typically die in their mid-twenties from complications of lung effects and affects approximately 4,300 patients per year in the United States and based on the number of treatable patients, has a potential addressable market of about $150 million. GTX-102 is comprised of a proprietary concentrated formulation of the glucocorticosteroid Betamethasone that can be sprayed conveniently over the tongue of the AT patient, who often has difficulty swallowing.
As I mentioned a moment ago, we initiated a phase I PK bridging study in the third calendar quarter of 2022 to evaluate the comparative bioavailability, pharmacokinetics, and safety of our oral Betamethasone spray, GTX-102, compared to an intramuscular injection of Betamethasone, the reference drug, and to an oral solution of Betamethasone in 48 healthy subjects. The first subject, first dose was administered on September 13th, 2022. This PK study is the next step in the clinical development pathway for GTX-102 and is expected to be completed with top-line results reported before calendar year-end. I look forward to sharing more with everyone in the coming weeks on this, important study.
Finally, let's discuss the progress that our team has made on GTX-101, our novel non-narcotic, thin film bioadhesive topical Bupivacaine spray designed to treat PHN, the severe and often debilitating nerve pain that can persist following a shingles infection. It's important to point out that market studies suggest a significant unmet need exists for treating these patients with PHN. Approximately 40% of patients who are prescribed the standard of care, which includes oral Gabapentin and Lidocaine patches, experience insufficient pain relief, and Gabapentin has unpleasant side effects. Consequently, many of these patients end up being prescribed more potent drugs such as opioids, which can be addictive. The potential benefits of GTX-101 could include faster onset of action, which is inherent in our active ingredient Bupivacaine versus Lidocaine, as well as a longer duration of pain relief.
GTX-101 can be conveniently sprayed on the skin wherever the pain is located and based on the PK, on the PK schedule will need to be confirmed in our clinical trials. We believe GTX-101 has the potential to be a disruptive therapy as a non-opioid analgesic for PHN patients who suffer from this debilitating pain. On July 26, 2022, we initiated the PK bridging study to evaluate the relative bioavailability of GTX-101 compared to the reference-listed drug Bupivacaine in 48 healthy subjects. The PK study is the next step in our clinical development pathway for GTX-101. The PK study is expected to be completed by the end of calendar 2022 as planned and is expected to provide important information on the dose and dosing frequency for additional clinical studies of GTX-101 in humans in 2023.
I look forward to sharing more with everyone in the coming weeks on this study. Let me recap quickly before I turn it over to Brian for a quick review of our Q2 numbers. First, we expect to receive guidance from the FDA on our proposed phase III safety study design for GTX-104 in the form of a Type C meeting no later than early in the first calendar quarter of 2023. This should allow us to initiate the phase III safety study and begin enrolling the first patient as planned in the H1 of 2023. The study is expected to take about 18 months to complete and is expected to be the final clinical step required to seek approval under the 505(b)(2) regulatory pathway.
The PK bridging study of GTX-102 was initiated on September 13, 2022, and we expect to report out top line results on schedule next month before the end of calendar 2022. Assuming the PK bridging study meets its primary endpoint, we expect that the final development step is to conduct a phase III safety and efficacy trial in AT patients. We plan to request a Type B meeting with the FDA following the completion of the PK study to confirm the phase III study design, and the phase III study is expected to be initiated in the H2 of 2023. If both studies meet their primary endpoints an NDA filing for GTX-102 under Section 505(b)(2) would follow.
The single dose study of GTX-101 was initiated on July 26, 2022 in healthy human volunteers. This PK study is the next step in our proposed 505(b)(2) regulatory pathway for GTX-101, and the PK study is expected to be completed by the end of calendar 2022 as planned and should provide important information on the dose and dosing frequency for additional clinical studies of GTX-101 in humans in 2023. Finally, it's important to note that we finished the second fiscal quarter ending September 30, 2022, with about $35 million in cash equivalents, and short-term investments.
We continue to believe that this is sufficient capital to fund operations through at least March of 2024, allowing for the advancement of GTX-104 well into phase III and advancing GTX-102 and GTX-101 to key value inflection points. We're very excited about the prospects ahead for the company, and we look forward to keeping you apprised of our progress towards our many milestones this new fiscal year. I'd like to now turn the call over to Brian Ford, our CFO, to review our financial results. At the conclusion of Brian's remarks, we'll open the call for your questions. Brian?
Thanks, Jan. Please note that unless otherwise indicated, all financial numbers that we discuss are denominated in US dollars and the financials are reported conforming to US GAAP guidelines. We should also note that we are a clinical stage company, thus we do not yet generate revenues or have any cost of goods expenses. Research and Development expenses net of government assistance for the three months ending September 30th, 2022 totaled $3.3 million compared to $0.6 million for the three months ending September 30th, 2021. Our Research and Development during the quarter ended September 30th, 2022, focused primarily on advancing our clinical development programs for our GTX-104, GTX-102, and GTX-101 drug candidates.
General and administrative expenses for the quarter ended September 30th, 2022 were $1.6 million compared to $2.9 million for the quarter ended September 30th, 2021. This decrease was the result of decreased legal, tax, accounting and other professional fees that we incurred in connection with the Grace merger last year. The decrease in professional fees was partially offset by an increase in salaries and benefits due to the renewed accrual for our employee incentive bonus program. Loss from operating activities for the quarter ended September 30th, 2022 was $5.1 million compared to a $3.6 million loss for the quarter ended September 30th, 2021.
Net loss and total comprehensive loss for the quarter ended September 30th, 2022 was $4.9 million or $0.11 loss per share compared to net income of $1 million or $0.03 per share for the quarter ended in 2021. Cash, cash equivalents and short-term investments totaled $34.9 million as of September 30, compared to $43.7 million in cash equivalents, and short-term investments as of March 31, 2022.
As Jan mentioned, we will continue to believe that we have sufficient capital to fund operations through at least March of 2024, which will include the ability to fund our lead asset, GTX-104, well into phase III and GTX-102 and GTX-105 to additional milestones. With that, I'll now turn the call back over to Jan.
Thanks, Brian. Before I turn it over to the operator for questions, I wanted to let everyone know we'll be participating in the Investor Summit conference tomorrow. If we don't already have a one-on-one meeting scheduled with you and you would like to arrange a meeting with us, please reach out to Robert Blum and he can coordinate getting a meeting scheduled. With that, I'd like to now turn the call over to the operator. Jason, can you open it up for questions?
Yes, thank you. We will now begin the Question and Answer session. To ask a question, you may press star then one on your touch-tone phone. If you're using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then two. At this time, we'll pause momentarily to assemble our roster. Our first question comes from Leland Gershell from Oppenheimer. Please go ahead.
Hey, good afternoon, and thanks for taking my questions. Just a question on 104. I know it's some time away, but just as you you know think about approaching the commercial market, you know, for the opportunity in SAH, to access those patients out there in hospitals and ICUs and so forth, what structure do you plan to deploy in terms of commercial organization and field reps, if you're able to speak to that? Thanks.
Yeah. Thank you, Leland. Thanks for being on the call today. Yeah. You know, the really nice thing about this market is that it's highly concentrated. You know, these patients present typically to a major, you know, healthcare center with usually a stroke ICU unit. There's about, you know, roughly 1,400 of those centers around the country. It's interesting because it's a typical 80-20 rule, or in this case, about 70% actually of the patients are treated in about 400 of those centers. We really believe that we can commercialize GTX-104 ourselves.
We think we can do this initially with just, you know, roughly 15-20 reps, and then grow organically as sales grow. We obviously would be targeting some of the larger centers around the country. I should mention, by the way, that we already have relationships with many of these centers. We expect, you know, a number of them to participate in our phase III safety study, and will be recruiting patients for us. You know, if we have a successful study and the drug gets approved, we would expect fairly rapid adoption. I should mention that we're, you know, we remain open to other, you know, potential partnering opportunities, not just in the U.S., but certainly outside of the U.S.
We think there's really a very attractive market, for example, in China. We have discussions just beginning, you know, in for potential partnership opportunities in Asia as well as potentially in Europe as well.
Thank you. Great. Just to confirm, we'll see the 102 sounds like sometime next month. We look forward to seeing that readout. Thanks very much for taking the questions.
Yeah. Sorry, I didn't catch the last part you cut out there. Were you asking about 102?
Yeah, just confirming that we'll see the top line by year-end.
Yes, absolutely. Yeah. We're planning to report out. That study should, we should have the top-line results before the end of December. So we will report that out as soon as we get the results.
Great. Look forward to it. Thanks so much.
Yeah. Thanks, Leland.
Again, if you have a question, please press star then one. Our next question comes from Sahil Kazmi from B. Riley Securities. Please go ahead.
Yeah, thank you. Good afternoon, Jan and team, and congratulations on another productive quarter, and thanks for taking our questions. Just have a couple here. Maybe if we can start with something that you were going over in the recap there. Could you just remind us when we can expect sort of potential filings for each of the programs and then sort of lay in your current balance sheet and capital requirements to that, you know, in the context of during the time of the GTX-104 filing? I know the runway's sufficient through there, but for the other programs as well.
Sure. Yeah. We have, you know, disclosed that we would expect that the GTX-104 study will start as planned in the H1 of next year. Actually, in the second quarter, we would expect to see the first patient in. That study is expected to enroll about 100 patients. We'll have two arms. It'll, you know, 50 of those patients will be on the oral Nimodipine and 50, roughly 50 on our IV GTX-104. We expect it'll take about a year to enroll those patients, and with a short follow-up period, the whole study is expected to take about 18 months. You know, we would expect to you know, wrap up the study.
If we were able to start mid next year, would expect to wrap up the study towards the end of 2024, you know, and then file in early 2025. Again, we hope we'll get, you know, Fast Track on this. But assuming, you know, a 10-month review cycle, which would be the conservative, we would expect to have approval before the end of 2025. I'll turn it over to Brian with regards to your balance sheet question. Brian, do you wanna take that one?
Sure. I'm not exactly certain what you meant by the Balance Sheet or capital requirements. You're just looking for how much is gonna be required to complete these programs?
Yeah. More just understanding how we can think about the Burn going forward at this, you know, $5 million number that we're seeing this quarter as some of the studies get into these, you know, larger Safety Studies. Should we expect sort of along the same trajectory?
Yeah. Okay, my expectation and our expectation is that our long run Burn Rate is about $2 million a month. That's kind of, you can take that from looking at our $35 million. It'll last us for the next 18 months through March of 2024. Beyond that, as we start to commercialize, I would expect our Burn Rate to increase a little bit, just to cover the cost of commercialization and the build-out of our commercial infrastructure. You know, at the same time we'll be looking at other ways to monetize and raise funds to support that commercialization effort.
Excellent. Maybe one more for Jan or Prashant if he's on the call as well. Could you remind us of some of the market research that's been generated from the GTX-101 program?
Sure, yeah. Maybe I'll turn that over to Prashant. You wanna cover that one?
Yeah, happy to. Hi, Sahil. So, you know, earlier this year we refreshed our market assessment primary research for GTX-101. This is for postherpetic neuralgia. The results, the findings were astounding, you know, to put it mildly, I guess. You know, we interviewed over 250 primary care physicians and pain specialists, specifically socialized the Target Product Profile for GTX-101, and it was an overwhelming response, even in light of the Lidocaine patches, as you know, is mostly the standard of care with the Gabapentin. As Jan had mentioned, both of them have unmet needs out there, which came out very clearly in the survey findings of these physicians.
The perception was GTX-101 would meet a need out there in terms of faster analgesia, as well as a potential drug that would be more convenient to use and apply. It validated our hypothesis that there is an unmet need for PHN out there that GTX-101 would fulfill very nicely. The other aspect of our primary research was to look at reimbursement and what the impact of Shingrix vaccine is on the overall Lidocaine patch market. Just to remind everyone that Lidocaine patches have the only approved indication for Postherpetic Neuralgia. What we found was only a tenth of scripts are being written for the patches. Majority of the others are for back pain, osteoarthritis, Diabetic Peripheral Neuropathy.
In over half the instances, the major insurance companies are routinely approving those prescriptions for the Non-PHN pain indications. The market opportunity we think for GTX-101 is very attractive, you know, with PHN as well as beyond for extension opportunities. Shingrix during the period Shingrix was launched, we analyzed the uptick curve of the Lidocaine patches, and they have grown at a healthy CAGR of 7%. It's these Non-PHN indications as well that we believe is a robust driver for GTX-101. I'll just pause here, if you have any further questions or Jan, if you would like to add anything.
No, I thought that was a good summary, Prashant. Thank you. Sahil?
Yeah, no, that's fantastic, Prashant. Thank you so much for that additional color and for taking a lot of our questions. We look forward to seeing some of the data by the end of the year.
Yeah, thanks, Sahil. Really appreciate you being on the call today.
Absolutely. Thanks.
There are no more questions in the question queue. This concludes our question and answer session. I'd like to turn the conference back over to management for any closing remarks.
Okay. Thank you, Jason. Appreciate it. I wanna thank everyone for taking the time to be with us today on the call. We're really excited about the progress we're making to deliver innovative new treatments to thousands of patients who currently lack effective therapies. We really look forward to updating you on our progress towards several key milestones coming in the next few months. Thanks again, and I wish you all a great day. Take care.
Conference is now concluded. Thank you for attending today's presentation. You may now
