Grace Therapeutics LLC

Name Change Reflects Extensive Scientific and Corporate Brand Equity Previously Established under Grace Therapeutics Grace Therapeutics will begin trading on Nasdaq under the trading symbol "GRCE" effective October 28, 2024 Virtual Key Opinion Leader Event to be held on November 20th PRINCETON, N.J., Oct. 25, 2024 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (Nasdaq: ACST) (Acasti or the Company), a late-stage, biopharma company advancing GTx-104, its novel injectable formulation of nimodipine that addresses high unmet medical needs for a rare disease, aneurysmal subarachnoid hemorrhage (aSAH), today announced that it is changing its name to Grace Therapeutics, Inc. (Grace Therapeutics). Grace Therapeutics was the name of the company developing GTx-104 prior to its merger with Acasti in 2021. Grace Therapeutics will begin trading on Nasdaq under the trading symbol “GRCE” at the open of the market on October 28, 2024 and all company branding including corporate website will be updated accordingly. “The Grace Therapeutics brand reconnects us to our roots that are steeped in scientific innovation and highlights our transformative journey,” said Prashant Kohli, CEO of Acasti. “The breakthrough formulation of GTx-104 is the result of a decade of research by our exceptional scientific team while Grace Therapeutics was located in the pharma industry research corridor of New Jersey. We have continued to make significant progress in the clinical development plan of GTx-104, including full enrollment of the STRIVE-ON trial and anticipate a data readout in early calendar 2025 with an expected submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the first half of calendar 2025. “In addition to advancing GTx-104 over the past 18 months, we successfully restructured to an agile biopharma model, rebuilt the management team, prioritized the pipeline, divested legacy assets, strengthened the balance sheet, and re-domiciled to the United States as a Delaware corporation. We believe these steps offer several potential benefits, including a U.S. corporate structure that should increase the company’s attractiveness and marketability to potential strategic partners and global institutional investors. We are proud of the progress made within a relatively short timeframe and look forward to fully realizing the Company’s value under the Grace Therapeutics brand.” The Company will host a Key Opinion Leader (KOL) event titled Virtual KOL Event on GTx-104 in aneurysmal Subarachnoid Hemorrhage, on November 20, 2024 at 2pm Eastern Time.

About the Acasti Asset Portfolio GTx-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for intravenous (IV) infusion in aSAH patients to address significant unmet medical needs. The unique nanoparticle technology of GTx-104 facilitates aqueous formulation of insoluble nimodipine for a standard peripheral IV infusion. GTx-104 provides a convenient IV delivery of nimodipine in the Intensive Care Unit potentially eliminating the need for nasogastric tube administration in unconscious or dysphagic patients. Intravenous delivery of GTx-104 also has the potential to lower food effects, drug-to-drug interactions, and eliminate potential dosing errors. Further, GTx-104 has the potential to better manage hypotension in aSAH patients. GTx-104 has been administered in over 150 healthy volunteers and was well tolerated with significantly lower inter- and intra-subject pharmacokinetic variability compared to oral nimodipine. The addressable market in the United States for GTx-104 is estimated to be about $300 million, based on market research. GTx-102 is a novel, concentrated oral-mucosal spray of betamethasone intended to improve neurological symptoms of Ataxia-Telangiectasia (A-T), for which there are currently no FDA-approved therapies. GTX-102 is a stable, concentrated oral spray formulation comprised of the gluco-corticosteroid betamethasone that, together with other excipients can be sprayed conveniently over the tongue of the A-T patient and is rapidly absorbed. The further development of GTx-102 has been deprioritized in favor of our focus on development of GTx-104. It is also possible that we may license or sell our GTx-102 drug candidate. GTx-101 is a non-narcotic, topical bio-adhesive film-forming bupivacaine spray designed to ease the symptoms of patients suffering with postherpetic neuralgia (PHN). GTx-101 is administered via a metered-dose of bupivacaine spray and forms a thin bio-adhesive topical film on the surface of the patient’s skin, which enables a touch-free, non-greasy application. It also comes in convenient, portable 30 ml plastic bottles. Unlike oral gabapentin and lidocaine patches, we believe that the biphasic delivery mechanism of GTx-101 has the potential for rapid onset of action and continuous pain relief for up to eight hours. No skin sensitivity was reported in a Phase 1 trial. The further development of GTx-101 has been deprioritized in favor of our focus on development of GTx-104. It is also possible that we may license or sell our GTx-101 drug candidate. About Acasti Acasti is a late-stage biopharma company with drug candidates addressing rare and orphan diseases. Acasti’s novel drug delivery technologies have the potential to improve the performance of currently marketed drugs by achieving faster onset of action, enhanced efficacy, reduced side effects, and more convenient drug delivery. Acasti’s lead clinical assets have each been granted Orphan Drug Designation by the FDA, which provides seven years of marketing exclusivity post-launch in the United States, and additional intellectual property protection with over 40 granted and pending patents. Acasti’s lead clinical asset, GTx-104, is an intravenous infusion targeting aneurysmal Subarachnoid Hemorrhage (aSAH), a rare and life-threatening medical emergency in which bleeding occurs over the surface of the brain in the subarachnoid space between the brain and skull.

Company to Host Conference Call Today at 1:00pm ET LAVAL, Québec, Feb. 14, 2023 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST), a late-stage, specialty pharma company advancing three clinical stage drug candidates addressing rare and orphan diseases, today announced financial and operational results for the third quarter ended December 31, 2022 Recent Highlights The Company anticipates receiving clarifying guidance from the Food and Drug Administration (FDA) on its proposed phase 3 study design for GTX-104 through a written Type C meeting in the first calendar quarter of 2023. The Company expects that favorable FDA guidance would allow Acasti to initiate the Phase 3 safety study and begin recruiting clinical sites and enrolling patients. The Company expects the study to take about 18 months to complete once the first patient is enrolled, and if the trial is successful, the Company expects that it will be the final clinical step required to seek FDA approval under the 505(b)(2) regulatory pathway.Preliminary topline results of the pharmacokinetic (PK) bridging study for GTX-102 announced in December 2022 met all primary outcome measures. The objectives of the study were to evaluate the bioavailability, pharmacokinetics, and safety of GTX-102, a novel, concentrated oral-mucosal metered spray of betamethasone in healthy volunteers, and to compare the PK profile to an intramuscular injection of betamethasone, the reference drug, which is approved in the U.S. Acasti’s new and patented formulation of betamethasone is intended to improve the neurological symptoms of Ataxia Telangiectasia (A-T) in a pediatric population for which there are currently no FDA-approved therapies. The Company expects that the next step in the proposed 505(b)(2) regulatory pathway for GTX-102 will be a Phase 3 safety and efficacy study in children with A-T, which could be initiated following a Type B meeting with the FDA.Preliminary topline results announced in December 2022 for the Company’s single-dose PK study to evaluate the relative bioavailability of GTX-101 compared to the reference listed drug in the U.S., bupivacaine subcutaneous injectable, met all primary outcome measures for the study. The Company anticipates receiving the final clinical study report in the first half of calendar 2023. This PK study was the next step in the Company’s proposed 505(b)(2) regulatory pathway for GTX-101 and it provided important information on the dose and dosing frequency in humans for future clinical studies.The Company finished the second fiscal quarter ended December 31, 2022, with $31.3 million in cash, cash equivalents and short-term investments. Management continues to believe that based on current projections, the Company has sufficient capital to fund operations into calendar Q2 of 2024 allowing for the advancement of GTX-104 well into Phase 3 and advancing GTX-102 and GTX-101 to additional important milestones. Management Discussion Jan D’Alvise, Chief Executive Officer of Acasti, said “Significant progress was made over the past few months on all three of our clinical programs. We ended calendar 2022 in a very strong fashion with the completion of two successful clinical trials, and we announced important pharmacokinetic study results for both GTX-101 and GTX-102 in late December. In both cases, the preliminary topline results met all outcome measures. These positive results allow us to advance both programs to the next stage of clinical development in 2023. We expect 2023 to be very exciting for Acasti with two of our drug candidates ready to enter Phase 3. We look forward to receiving clarifying guidance from the FDA in calendar Q1 2023 on the Phase 3 study design for our lead program, GTX-104, a novel formulation of nimodipine for continuous IV infusion in patients suffering from subarachnoid hemorrhage. We are hopeful that this FDA feedback will confirm our 505(b)(2) regulatory strategy and allow us to finalize the study protocol, paving the way for the initiation of our Phase 3 safety study later this year.” Program Updates GTX-104: GTX-104 is a clinical stage, novel formulation of nimodipine to be administered via continuous IV infusion for treating aSAH patients. Subarachnoid hemorrhage (SAH) is bleeding over the surface of the brain in the subarachnoid space between the brain and the skull, which contains blood vessels that supply the brain. A primary cause of such bleeding is rupture of an aneurysm (aSAH). The Company anticipates receiving clarifying guidance from the FDA on its proposed phase 3 study design for GTX-104 in the form of a written Type C meeting in the first calendar quarter of 2023. The Company expects that favorable FDA guidance would allow the Company to initiate the Phase 3 safety study and begin recruiting clinical sites and enrolling patients. Once the first patient is enrolled, the Company expects the study to take about 18 months to complete, and if the trial is successful, the Company expects that it will be the final clinical step required to seek FDA approval under the 505(b)(2) regulatory pathway. GTX-102: GTX-102 is a novel, concentrated oral-mucosal spray of betamethasone intended to improve the neurological symptoms of A-T, for which there are currently no FDA-approved therapies. GTX-102 is comprised of a proprietary formulation of the gluco-corticosteroid betamethasone that can be sprayed conveniently over the tongue of the A-T patient. The Company initiated its PK bridging study as planned in fiscal Q2 2022 to evaluate the comparative bioavailability, pharmacokinetics, and safety of GTX-102, compared to an intramuscular injection (IM) of betamethasone and to an oral solution of betamethasone, in 48 healthy subjects. On December 28, 2022, the Company reported that the topline results of this study met all primary outcome measures. Results showed that GTX-102 betamethasone blood concentrations were highly predictable and consistent based on AUC and Cmax, indicating good linearity and dose-proportionality. GTX-102 betamethasone blood concentrations were within the same range of exposure as IM betamethasone, based on AUC. Acasti is proposing that this IM formulation will serve as a bridge for GTX-102 for the 505(b)(2) regulatory pathway. GTX-102 betamethasone blood concentrations were also within the same range of exposure as the oral solution (OS), based on AUC. This OS formulation is not available in the US and was used in a published clinical trial conducted in Europe (Zannolli, et.al.), and may serve as a comparator for further clinical development. Furthermore, statistically there was no significant difference (p>0.05) between GTX-102 administered at a fast rate (each spray immediately following the preceding one) vs. a slow rate (1 spray/minute), as indicated by Cmax and AUC. The Company believes this finding is important because being able to use the fast or the slow rate of administration may provide greater flexibility for patients and caregivers. The Cmax of GTX-102 was within the same range of exposure as the OS, but the Cmax for the IM formulation was lower than both GTX-102 and the OS, as well as what has been reported previously for the IM in the literature. It is important to note that achieving bioequivalence with the IM was not an objective of this study, nor was it expected. Finally, no serious adverse events (AE) were reported, and the most frequent drug-related AE was mild headache (4 cases). Based on this data, Acasti will work with its clinical experts and the FDA to determine the optimal final dosing regimen for GTX-102 to incorporate into its Phase 3 study design. Based on previous discussions with the FDA, the Company plans to conduct a confirmatory Phase 3 safety and efficacy trial in A-T patients, and plan to seek clarifying guidance from the FDA on the study design at a Type B meeting. The Company expects the Phase 3 study to be initiated following the Type B meeting. If both studies meet their primary endpoints, a Pre-NDA meeting with the FDA and an NDA filing under Section 505(b)(2) would follow. GTX-101: GTX-101 is a non-narcotic, topical bio-adhesive film-forming bupivacaine spray designed to treat postherpetic neuralgia (PHN), the severe and often debilitating nerve pain that can persist following a shingles infection. The data from a single dose Phase 1 clinical trial for GTX-101 along with regulatory guidance from the FDA’s Division of Anesthesiology has informed the design of additional preclinical toxicology studies and a proposed clinical and regulatory pathway to approval. On July 26, 2022, the Company initiated its single dose PK study to evaluate the relative bioavailability of GTX-101 compared to the reference listed drug, bupivacaine, in 48 healthy subjects. Topline results from this study were reported on December 23, 2022, and the results met all primary outcome measures. The median Tmax of bupivacaine in plasma following GTX-101 single-dose topical applications ranged between 18 to 24 hours depending on dose, while the median Tmax following the subcutaneous injection of 10 mg of bupivacaine was only 23 minutes. This result suggests that bupivacaine delivered by GTX-101 remains in the skin for a long period of time, potentially inducing a prolonged analgesic effect in the sprayed area. The exposure to bupivacaine based on Cmax and AUC following GTX-101 topical application as a single-dose increased with increasing dose. The systemic exposure to bupivacaine following a 200mg dose of GTX-101 was approximately 29-fold less than a single subcutaneous dose of 10mg of bupivacaine based on Cmax and approximately 6-fold less than a single subcutaneous dose of 10mg of bupivacaine based on AUC. The Company expects these results will correspond to an increased safety margin for GTX-101 with regards to toxicity risk. Mean half-life (T half) following GTX-101 single-dose topical applications ranged between 24 to 37 hours depending on dose, suggesting a slow elimination and potentially long duration of effect, while mean Tmax following the subcutaneous injection of 10 mg of bupivacaine was only 8 hours. There were only two AEs determined to be related to the study drug by the investigator for each of GTX-101 and the bupivacaine subcutaneous injection. Following GTX-101 topical application, headache (1 event = 3%) and numbness (1 event = 3%) at the sprayed area; following bupivacaine subcutaneous injection, dizziness (1 event = 8%) and nausea (1 event = 8%). The Company plans to follow this successful PK study with a multiple ascending dose study in 2023. Results from these non-clinical and clinical studies are required before the initiation of the Company’s Phase 2 program in PHN patients. Q3 2023 Financial Results The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and are presented in U.S. dollars. Research and development expenses, net of government assistance for the three months ended December 31, 2022, totaled $2.5 million compared to $2.2 million for the three months ended December 31, 2021. Our research and development during the quarter ended December 31, 2022, was focused primarily on our clinical development programs for our GTX-104, GTX-102, and GTX-101 drug candidates. General and administrative expenses for the three months ended December 31, 2022 were $1.6 million compared to $1.8 million for the three months ended December 31, 2021. This decrease was a result of decreased legal, tax, accounting and other professional fees that had been incurred in connection with our acquisition of Grace Therapeutics Inc. in August 2021. Loss from operating activities for the three months ended December 31, 2022 was $4.2 million compared to a loss of $4.5 million for the three months ended December 31, 2021. For the three months ended December 31, 2022 a financial gain of $0.8 million resulted mostly due to the decrease in the fair value of the derivative warrant liabilities. Net loss and total comprehensive loss for the three months ended December 31, 2022 was $(3.9) million, or $(0.09) loss per share, compared to a net loss of $(3.8) million, or $(0.09) income per share, for the three months ended December 31, 2021. Cash, cash equivalents and short-term investments totaled $31.3 million as of December 31, 2022, compared to $34.9 million in cash, cash equivalents and short-term investments as of September 30, 2022. Based on management’s current projections, current cash, cash equivalents and short-term investments are expected to continue to fund our lead asset GTX-104 well into Phase 3, and GTX-102 and GTX-101 to additional important milestones.

LAVAL, Québec, Sept. 30, 2022 (GLOBE NEWSWIRE) -- Acasti Pharma Inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST), a late-stage, specialty pharma company advancing three clinical stage drug candidates addressing rare and orphan diseases, announced today that a U.S. court has dismissed the remaining stockholder litigation filed in connection with the Company’s acquisition of Grace Therapeutics, Inc. (“Grace”) via merger in August 2021 (the “Merger”). As previously disclosed, four stockholder lawsuits were filed against Acasti and certain of its directors and officers in connection with the Merger, claiming that the Company’s public disclosures relating to the Merger misstated or omitted material information and violated Section 14(a) of the U.S. Securities Exchange Act of 1934. Two of the four cases were voluntarily dismissed. The remaining two cases were consolidated before Judge Katherine Polk Failla in the United States District Court for the Southern District of New York. Acasti and the individual defendants filed a motion to dismiss on February 25, 2022. In a 45-page opinion released earlier today, Judge Failla granted the motion to dismiss in its entirety, finding that the consolidated complaint failed to allege any facts showing that Acasti made a materially misleading statement or material omission in its Merger-related disclosures. Accordingly, subject to any appeal that may be taken in response to today’s ruling, all four stockholder suits filed in connection with the Merger have now been dismissed. About Acasti Acasti is a late-stage, specialty pharma company advancing three clinical stage drug candidates addressing rare and orphan diseases. Acasti’s novel drug delivery technologies have the potential to improve the performance of currently marketed drugs by achieving faster onset of action, enhanced efficacy, reduced side effects, and more convenient drug delivery—all which could help to increase treatment compliance and improve patient outcomes.

Acasti’s lead clinical assets target underserved orphan diseases: (i) GTX-104, an intravenous infusion targeting Subarachnoid Hemorrhage (SAH), a rare and life-threatening medical emergency in which bleeding occurs over the surface of the brain in the subarachnoid space between the brain and skull; (ii) GTX-102, an oral mucosal spray targeting Ataxia-telangiectasia (A-T), a progressive, neurodegenerative genetic disease that primarily affects children, causing severe disability, and for which no treatment currently exists; and (iii) GTX-101, a topical spray targeting Postherpetic Neuralgia (PHN), a persistent and often debilitating neuropathic pain caused by nerve damage from the varicella zoster virus (shingles), which may persist for months and even years.
