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
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.
