WALTHAM, Mass., March 25, 2024 (GLOBE NEWSWIRE) — Aerovate Therapeutics, Inc. (Nasdaq: AVTE), a clinical stage biopharmaceutical company focused on developing drugs that meaningfully improve the lives of patients with rare cardiopulmonary disease, today announced financial results for the year ended December 31, 2023, and recent business highlights.

“Aerovate reached important milestones in 2023 with the achievement of full enrollment of the Phase 2b portion and the first patient enrolled in the Phase 3 portion of our IMPAHCT trial evaluating AV-101 for patients with PAH,” said Tim Noyes, Chief Executive Officer of Aerovate. “In 2024, we look forward to presenting baseline characteristics of IMPAHCT at the ATS international conference in May, as well as announcing Phase 2b topline data in June with the full Phase 2b clinical trial results to be presented at an upcoming scientific meeting. We remain confident that delivering our proprietary formulation of imatinib directly to the pulmonary vasculature via inhalation has the potential to achieve robust efficacy with a low side effect burden in PAH patients on two or three background therapies. As such, we continue to believe that AV-101 has the potential to be an important part of the future standard of care for PAH patients.”

2023 Highlights

Enrollment Complete and Topline Data Expected in June 2024 from Phase 2b Portion of the IMPAHCT Global Phase 2b/Phase 3 Clinical Trial. IMPAHCT (Inhaled iMatinib Pulmonary Arterial Hypertension Clinical Trial) is a global Phase 2b/Phase 3 trial of AV-101, our self-administered, twice daily dry powder inhaled formulation of the antiproliferative drug imatinib for the treatment of PAH. PAH is a devastating disease impacting approximately 70,000 people in the United States and Europe. In November 2023, we announced completion of enrollment at 202 adult patients in the Phase 2b portion of the IMPAHCT trial, and we continue to expect to provide topline data in June 2024.

First Patient in Phase 3 Portion of IMPAHCT Enrolled in November 2023. Due to the seamless trial design, we were able to enroll our first patient in the Phase 3 portion of the IMPAHCT trial in the same month we completed enrollment in our Phase 2b portion of the IMPAHCT trial. Enrollment continues with over 120 clinical sites participating in the Phase 3 portion of the trial. The timing for topline Phase 3 data and the size of the Phase 3 portion of the trial will be determined based upon the results from the Phase 2b portion of the trial.

Trial Data Published and Presented at Scientific Conferences. We presented at the American Thoracic Society (ATS) 2023 International Conference results in nonclinical species that (i) direct delivery of imatinib to the lungs demonstrated increased lung exposure compared with oral or IV dosing and (ii) the type of formulation impacted lung exposure with dry powder demonstrating greater lung exposure than suspension or solution and greater lung exposure versus oral or intravenous delivery.

Expanded Intellectual Property Portfolio. We continued expanding our intellectual property portfolio in 2023 with the issuance of two additional patents bringing the total issued patents to six. In 2023, the United States Patent and Trademark Office issued Patents 11,806,349 and 11,813,263 to us, and we continue prosecuting multiple additional applications to cover our product globally.

Expanded Board of Directors with Experience in PAH. We appointed Habib Dable and Donald Santel to our Board of Directors. In March 2024, Mr. Dable was also appointed as Chair of our Board of Directors, as successor to Mark Iwicki, who remains a member of our Board. Mr. Dable is on three public biopharmaceutical company boards and was previously Chief Executive Officer of Acceleron Pharma Inc. at the time of its sale to Merck & Co., Inc. Mr. Santel serves on the board of directors of three biopharmaceutical companies and as chair of two of them. Mr. Santel previously served as Chief Executive Officer for CoTherix, Inc., a biopharmaceutical company focused on developing therapies for cardiopulmonary disease, including PAH.

2023 Financial Results

Cash, cash equivalents and short-term investments totaled $122.4 million as of December 31, 2023, compared to $135.2 million as of September 30, 2023. The decrease was primarily driven by operational costs for the three-month period ended December 31, 2023.

R&D expenses: Research and development (R&D) expenses for the year ended December 31, 2023 were $64.2 million as compared to $38.6 million for the year ended December 31, 2022. The increase in R&D expenses was due primarily to clinical trial costs, manufacturing costs, and increased headcount-related costs in 2023 as compared to 2022.

G&A expenses: General and administrative (G&A) expenses for the year ended December 31, 2023 were $17.2 million as compared to $14.6 million for the year ended December 31, 2022. The increase in G&A expenses was due primarily to increased headcount-related costs, travel and other miscellaneous costs in 2023 as compared to 2022.

Net loss: Net loss for the year ended December 31, 2023 was $75.5 million as compared to $51.5 million for the year ended December 31, 2022. Net loss included stock-based compensation expense of $11.9 million and $5.5 million for the years ended December 31, 2023 and December 31, 2022, respectively.

Financial guidance: We expect that our cash, cash equivalents and available-for-sale investments will be sufficient to fund our operations into 2026, based on our current operating plan.

About AV-101

AV-101 is an investigational, proprietary dry powder inhaled formulation of the antiproliferative drug imatinib. Developed specifically for pulmonary arterial hypertension (PAH), AV-101 targets cellular hyperproliferation and resistance to apoptosis, driven by improper signaling in cells of the distal pulmonary arteries. By targeting the proliferation and accumulation of cells in the arteries of the lungs, we believe AV-101 has the potential to provide meaningful improvements for patients beyond the capabilities of currently approved therapies. AV-101 is designed for delivery by an easy-to-use dry powder inhaler, directly into the lungs to maximize potential clinical benefit and limit systemic adverse effects. Phase 1 results published in ERJ Open Research showed that AV-101 delivered by dry powder inhalation was generally well-tolerated by healthy adult volunteers with no serious adverse events reported. Aerovate has completed enrollment in the Phase 2b portion of the IMPAHCT clinical trial and is currently enrolling patients in the Phase 3 portion to evaluate the safety and efficacy of AV-101 in adults with PAH.

About the IMPAHCT Trial

IMPAHCT (Inhaled iMatinib Pulmonary Arterial Hypertension Clinical Trial) is a multi-national, placebo-controlled Phase 2b/Phase 3 trial in adults with PAH that continuously enrolled patients as the study progresses from Phase 2b to Phase 3. The Phase 2b portion of the trial will evaluate three doses of AV-101 over 24 weeks, compared to placebo, to identify an optimal dose based on the primary endpoint, change in pulmonary vascular resistance (PVR), and safety, tolerability, and other clinical measures. The Phase 3 portion of the trial will compare patients taking the optimal dose of AV-101, selected from the Phase 2b data, to placebo. The primary endpoint of the Phase 3 portion of the trial will be change in six-minute walk distance (6MWD) over 24 weeks versus placebo. More information about this trial is available at https://clinicaltrials.gov/ct2/show/NCT05036135https://clinicaltrials.gov/ct2/show/NCT05036135.
