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.
