Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Thank you, Robert, and 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 3 clinical programs. We remain on track to initiate and enroll the first patient in our Phase III safety study for GTX-104 in the first half 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 2 PK bridging studies, one for GTX-102, our novel concentrated oral mucosal spray, a betamethasone intended to improve the neurodegenerative symptoms of ataxia-telangiectasia, or AT, in pediatric patients. And 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 Vericel zoster virus, the same virus that causes chickenpox.Â
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 second half 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 GTX101 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 30, 2022, with about $35 million in cash, 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 we'll fund the advancement of GTX-104 well into Phase III and allow us to advance GTX-102 and 101 to additional key inflection points. Taking a step back, and 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 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.Â
And as I've mentioned before, all 3 of our drug candidates have already received orphan drug designation from the FDA and have the potential to be considered for fast-track review and approval. Orphan drug designation provides for 7 years of marketing exclusivity in the United States post-launch, provided certain conditions are met in 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 available therapies. Or 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 the 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. So 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 neumotapine 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.Â
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% to 15% of them die before they ever reach the hospital, and only about 1/3 ultimately survive. Another 1/3 of these patients require dependent care for the rest of their lives. So 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-GTX104 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 had helped 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.Â
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 first half 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 SH 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 is 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 3 to 4 weeks or sometimes even longer, depending on the severity of the patient's condition.Â
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 a 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-20s from complications of lung effects which affect 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 AT patients who often have 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 beta medicine 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's first dose was administered on September 13, 2022.Â
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. And 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 PH, 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, experienced insufficient pain relief and gabapentin has unpleasant side effects.Â
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 the 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 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.Â
So 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 first half 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 second half of 2023. If both studies meet their primary endpoints and 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 GTX101 in humans in 2023. And finally, it's important to note that we finished the second fiscal quarter ending September 30, 2022, with about $35 million in cash, cash equivalents, and short-term investments.
We continue to believe that this is sufficient capital to fund operations through at least March of 2024, aligned for the advancement of 104 well into Phase III and advancing GTX-102 and 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 toward 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. And at the conclusion of Brian's remarks, we'll open the call for your questions. Brian?
Brian D. Ford - CFO
Thanks, Jan. Please note that unless otherwise indicated, all financial numbers that we discuss are denominated in U.S. dollars, and the financials are reported conforming to U.S. 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 3 months ended September 30, 2022, totaled $3.3 million compared to $0.6 million for the 3 months ended September 30, 2021. Our research and development during the quarter ended September 30, 2022, focused primarily on advancing our clinical development programs for our GTX-104,102 and 101 drug candidates. General and administrative expenses for the quarter ended September 30, 2022, were $1.6 million compared to $2.9 million for the quarter ended September 30, 2021. This decrease was the result of decreased legal, tax, accounting, and other professional fees that we incurred in connection with the gross margin. 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.Â
Loss from operating activities for the quarter ended September 30, 2022, was $5.1 million compared to a $3.6 million loss in the quarter ended September 30, 2021. A Net loss and total comprehensive loss for the quarter ended September 30, 2022, was $4.9 million or $0.11 loss per share compared to net income of $1 million or $0.03 per share income of $0.03 per share for the quarter ended in 2021. Cash equivalents and short-term investments totaled $34.9 million as of September 30, compared to $43.7 million in cash, cash equivalents, and short-term investments as at 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 would include the ability to fund our lead assets G-10 well into Phase III at EDS-102 and 105 to additional milestones. With that, I'll now turn the call back over to Jan.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
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 Bloom, 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?
Operator
Yes. We will now begin the question-and-answer session. (Operator Instructions) Our first question comes from Leland Gershell from Oppenheimer.
Leland James Gershell - MD & Senior Analyst
Just a question on 104. I know it's some time away, but just as you think about approaching the commercial market 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.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Yes. Thank you, Leiland, and thanks for being on the call today. Yes, the really nice thing about this market is that it's highly concentrated. These patients present typically to a major health care center with usually an ICU stroke unit. And there's about 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. So we really believe that we can commercialize GTX-104 ourselves. And we think we can do this initially with just roughly 15 to 20 reps and then grow organically as sales grow. So we obviously would be targeting some of the larger centers around the country. And I should mention, by the way, that we already have relationships with many of these centers.
We expect a number of them to be -- to participate in our Phase III safety study and we'll be recruiting patients for us. So we have a successful study, and the drug gets approved, we would expect fairly rapid adoption. I should mention that we're -- we remain open to other 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. So we have discussions just beginning for potential partnership opportunities in Asia as well as potentially in Europe as well.
Leland James Gershell - MD & Senior Analyst
And just to confirm, so we'll see the 10 sounds like sometime next month. So we look forward to seeing that readout.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Yes. Sorry, I didn't catch the last part you cut out there. Were you asking about 102?
Leland James Gershell - MD & Senior Analyst
Yes. Just confirming that we'll see the top line by year-end.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Yes, absolutely. Yes. We're planning to report out that study. 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.
Operator
(Operator Instructions)Â Our next question comes from Sahil Kazmi from B. Riley Securities.
Sahil Kazmi - Associate
Congratulations for another productive quarter. I 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 in the context of -- during the time of the 104 filings, I know the runway is sufficient through there, but for the other programs as well?
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Sure. Yes. So we have disclosed that we would expect the GTX-104 study will start as planned in the first half 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 2 arms. It will -- 50 of those patients will be on the oral nimodipine and 50 -- roughly 50 on our IV GTX-104. We expect it will 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. So we would expect to wrap up the study if we were able to start the mid-next year, would expect to wrap up the study towards the end of 2024, then file in early '25. And again, we hope we'll get fast track review on this. But assuming a 10-month review cycle, which would be conservative, we would expect to have approval before the end of 2025. And I'll turn it over to Brian with regard to your balance sheet question. Brian, do you want to take that one?
Brian D. Ford - CFO
Sure. I'm not exactly certain what you meant by the balance sheet or capital requirement is. You're just looking for how much is going to be required to complete these programs?
Sahil Kazmi - Associate
Yes. So more -- just understanding how we can think about the burn going forward at the $5 million number that we're seeing this quarter as some of the studies get into these larger safety studies. Should we expect sort of along the same trajectory?
Brian D. Ford - CFO
Yes. Okay. So my expectation, and our expectation is our long-run burn rate is about $2 million a month. So that's kind of -- you can take that from looking at our $35 million. It will last us for the next 18 months through March of '24. 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 as a build-out of our commercial infrastructure. But at the same time, we'll be looking at other ways to monetize and res funds to support that commercialization effort.
Sahil Kazmi - Associate
Excellent. And then maybe one more for Jan or if he's on the call as well. Could you remind us of some of the market research that's been generated from the 101 program?
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Sure. Yes. Maybe I'll turn that over to Prashant. Do you want to cover that one?
Prashant Kohli - Chief Commercial Officer
Yes. Happy to Sahil. So earlier this year, we refreshed our market assessment, primary research for GTX-101. This is for post herpaticneuralgia. And the results findings were astounding to put it mildly, I guess. 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. And 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. So 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. And just to remind everyone that lidocaine patches have the only approved indication is for post-hepatic neurology. And what we found was only 1/10 of scripts are being written for the patches. Majority of the others are for back pain, osteoarthritis, and diabetic trophon neuropathy -- and in over half the instances, the major insurance companies are routinely approving those prescriptions for the non-PHN pain indication. So the market opportunity, we think, for GTX-101 is very attractive with PHN as well as beyond for extension opportunities. Shingrix was -- during the PHN Rex was launched, we analyzed the uptick curve of the lidocaine patches, and they have grown at a healthy CAGR of 7%. So it's these non-PHN indications as well that we believe is a robust driver for GTX-101. So I'll just pause here if you have any further questions or Jan if you would like to add anything.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
No, I thought that was a good summary, for Sahil. Thank you.
Operator
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.
Janelle D'Alvise - President, CEO, Corporate Secretary & Director
Okay. Thank you, Jason. Appreciate it. I want to 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. And we really look forward to updating you on our progress toward several key milestones coming in the next few months. So thanks again, and I wish you all a great day. Take care.
Operator
The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
