WALTHAM, Mass., March 29, 2023 (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, 2022, and recent business highlights.

“Aerovate had a productive year in 2022 as evidenced by the progress made with our lead pipeline candidate AV-101 and strategic additions to our management team,” said Tim Noyes, Chief Executive Officer of Aerovate. “We believe AV-101, if approved, has the potential to become part of a new standard of care for patients with PAH by directly delivering a novel antiproliferative therapy to the pulmonary vasculature in a way that may offer broad efficacy and a low side effect burden to complement current and future treatment options. With its convenient twice daily dosing and easy-to-use pocket-size inhaler, we are optimistic about the potential of AV-101 to help us deliver on our vision of providing patients with meaningful treatment solutions.”

2022 Highlights

Progress Continued on the IMPAHCT Global Phase 2b/Phase 3 Clinical Trial. IMPAHCT (Inhaled iMatinib Pulmonary Arterial Hypertension Clinical Trial) is a 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 pulmonary arterial hypertension (PAH), a devastating disease impacting approximately 70,000 people in the United States and Europe. During 2022, we had additional clinical site activations and additional patients enrolled. We expect to report topline data from the Phase 2b portion of the trial in the fourth quarter of 2023 or first quarter of 2024.

Trial Data Published and Presented at Scientific Conferences. The Phase 1 AV-101 results, published in ERJ Open Research and presented at the American Thoracic Society (ATS) International Conference in May, demonstrated AV-101 delivered by dry powder inhalation to healthy adult volunteers was generally well-tolerated at doses from 10mg twice daily to 90mg twice daily with significantly reduced systemic exposure compared with 400mg oral imatinib, the dose used in Novartis’ IMPRES trial in PAH, and no serious treatment-emergent adverse events reported. In October 2022, the IMPAHCT trial design was presented at the American College of Chest Physicians Annual Meeting (CHEST) in a poster session. The adaptive, operationally seamless trial design for our Phase 2b/Phase 3 trial allows for continuous enrollment across phases and a more efficient drug development timeline.

Expanded Intellectual Property Portfolio. We continued expanding our intellectual property portfolio in 2022 with the issuance of four patents. The United States Patent and Trademark Office issued Patents 11,229,650, 11,298,355, 11,413,289, and 11,464,776. to us and we continue prosecuting multiple additional applications to cover our product globally.

Strengthened Management Team. We added four key members to our management team this past year, including the additions of Marco Verwijs as SVP, CMC (Chemistry, Manufacturing and Controls), Susan Fischer as SVP, Development Operations, Stephen Yu as SVP, Quality, and Sanjeev Khindri as SVP, Clinical Development. All have decades of experience in the biopharmaceutical space.

Expanded Board of Directors. We appointed Donald Santel to our Board and our Nominating and Corporate Governance Committee. Mr. Santel is Chairperson of the Board of two biopharmaceutical companies and was Chief Executive Officer for CoTherix, Inc., a biopharmaceutical company focused on developing therapies for cardiopulmonary disease, including PAH.

2022 Financial Results

Cash, cash equivalents and short-term investments totaled $129.2 million as of December 31, 2022, compared to $142.6 million as of September 30, 2022. The decrease was primarily driven by operational costs for the three-month period ended December 31, 2022.

R&D expenses: Research and development (R&D) expenses for the year ended December 31, 2022 were $38.6 million as compared to $15.0 million for the year ended December 31, 2021. The increase in R&D expenses was due primarily to clinical trial costs, manufacturing costs, and increased headcount-related costs in 2022 as compared to 2021.

G&A expenses: General and administrative (G&A) expenses for the year ended December 31, 2022 were $14.6 million as compared to $8.0 million for the year ended December 31, 2021. The increase in G&A expenses was due primarily to operating as a public company inclusive of insurance costs, legal and accounting fees, and increased headcount-related costs in 2022 as compared to 2021.

Net loss: Net loss for the year ended December 31, 2022 was $51.5 million as compared to $23.0 million for the year ended December 31, 2021. Net loss included stock-based compensation expense of $5.5 million and $2.0 million for the years ended December 31, 2022 and December 31, 2021, respectively.

Financial guidance: We expect that our cash, cash equivalents and available-for-sale investments will be sufficient to fund our operations into the second half of 2025, 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 the abnormal smooth muscle cellular hyperproliferation in the distal pulmonary arteries, caused by an imbalance of activity between growth factors and apoptosis. 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 presented at the 2022 American Thoracic Society (ATS) annual meeting showed that AV-101 delivered by dry powder inhalation was generally well-tolerated by healthy adult volunteers with no serious adverse events reported. Aerovate is enrolling patients in the IMPAHCT Phase 2b/Phase 3 clinical trial to evaluate the safety and efficacy of different doses 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 will continuously enroll 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/NCT05036135.
