AV-101 is being developed to address cellular hyperproliferation and resistance to apoptosis in the pulmonary vasculature, which are key features of the pathophysiology of PAH
PAH is an area of high unmet need, and currently approved therapies are limited by acting primarily through vasodilation
These Phase 1 results show that AV-101 delivered by dry powder inhalation was generally well tolerated and significantly reduced systemic exposure compared with oral imatinib in healthy adult participants
WALTHAM, Mass., May 16, 2022 (GLOBE NEWSWIRE) -- Aerovate Therapeutics, Inc. AVTE, a clinical-stage biopharmaceutical company focused on developing drugs that meaningfully improve the lives of patients with rare cardiopulmonary disease, today presents Phase 1 results at the American Thoracic Society (ATS) International Conference in San Francisco. Aerovate's data show that AV-101, a novel inhaled dry powder formulation of imatinib, was generally well-tolerated by healthy adult volunteers with no serious adverse events reported.
"We are pleased these Phase 1 data showed that AV-101 was generally well-tolerated in this trial of healthy adult volunteers across a dose range we believe may overlap or exceed lung exposures from 400 mg of oral imatinib, the dose used in the Novartis global Phase 3 IMPRES trial, while simultaneously reducing systemic exposure," said Timothy Noyes, Chief Executive Officer at Aerovate. "These findings represent an important step forward in our clinical development of AV-101, and support the selection of doses being evaluated in our ongoing Phase 2b/Phase 3 IMPAHCT trial."
Imatinib previously demonstrated a statistically significant and clinically meaningful benefit in PAH patients in the global Phase 3 IMPRES trial, conducted by Novartis, when administered orally as a tablet but was poorly tolerated due to adverse events. The development of oral imatinib for PAH was discontinued. Aerovate designed AV-101, a dry powder inhaled formulation of imatinib, to target imatinib's anti-proliferative activity in the pulmonary vasculature by direct delivery to the lungs while potentially avoiding the treatment-limiting systemic toxicities seen with oral imatinib.
Aerovate's Phase 1 trial evaluated single and multiple ascending doses of AV-101 administered by inhalation for safety, tolerability, and pharmacokinetics in healthy adult volunteers. The single ascending dose (SAD) portion of Aerovate's trial included 5 cohorts of 8 subjects each (6 randomized to AV-101, 2 placebo), who were administered a planned progression of 1 mg, 3 mg, 10 mg, 30 mg, and 90 mg single doses of inhaled AV-101 or placebo, compared to an additional cohort of 8 participants receiving 400 mg oral imatinib, the dose used in the IMPRES trial. The multiple ascending dose (MAD) portion consisted of 3 cohorts of up to 12 subjects each (9 randomized to AV-101, 3 placebo) who received AV-101 or placebo at either 10 mg, 30 mg, or 90 mg twice daily for 7 days. Only the morning dose was delivered on Day 7 so pharmacokinetics could be followed. Due to its known tolerability profile, the predicted steady-state exposure data for multiple doses of oral imatinib were obtained using a population pharmacokinetics model and data for oral imatinib 400 mg from the SAD study. At all doses, AV-101 demonstrated lower systemic exposure than oral imatinib. No serious treatment-emergent adverse events (TEAEs) were reported in either the SAD or the MAD cohorts. In the SAD portion of the trial, the most common TEAEs were dizziness and headache, whereas in the MAD portion of the trial, the most common TEAEs were short periods of cough and headache, primarily in the 90 mg cohort.
"Formulated as a dry powder for inhalation, AV-101 is designed to deliver high concentrations of imatinib throughout the airways and straight to diseased blood vessels," said Hunter Gillies, M.B.Ch.B., Chief Medical Officer at Aerovate. "By limiting systemic exposure and directly targeting the disease process of hyperproliferation in the pulmonary vasculature, AV-101 has the potential to make a meaningful difference for the PAH community."

AV-101 is an investigational, proprietary dry powder inhaled formulation of the anti-proliferative drug imatinib developed specifically for pulmonary arterial hypertension (PAH). 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. 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.
Pulmonary arterial hypertension (PAH) is a rare, progressive disease characterized by cellular hyperproliferation of the pulmonary vasculature that affects approximately 70,000 people in the United States and Europe. The disease process involves remodeling, constriction and occlusion of the small pulmonary arteries resulting in elevated blood pressure in the pulmonary circulation. PAH can cause strain on the heart, leading to limitation of physical activity, heart failure and reduced life expectancy. Existing vasodilator drugs fail to treat the underlying cellular proliferation causing the disease.
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 compared to placebo to identify an optimal dose based on the primary endpoint, change in pulmonary vascular resistance (PVR) over 24 weeks versus placebo, and safety, tolerability, and other clinical measures. The Phase 3 portion of the trial will compare patients taking the optimal dose selected in Phase 2b of AV-101 with 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.
