Aerami Therapeutics Announces Presentation of Phase 1 Clinical Trial Data for Lead Program AER-901 at the 2023 European Respiratory Society (ERS) International Congress

DURHAM, N.C., Sept. 12, 2023 (GLOBE NEWSWIRE) -- Aerami Therapeutics (“Aerami”), a clinical stage biopharmaceutical company dedicated to breathing life into the treatment of serious and rare cardiopulmonary diseases, today announced the presentation of results from the randomized double-blind, placebo-controlled Phase 1 clinical trial (NCT04903730) of AER-901 at the 2023 European Respiratory Society (ERS) International Congress. The ERS International Congress is being held September 9-13, 2023, at the MiCo convention center in Milan, Italy. The oral presentation and e-poster are available through the conference portal and will be posted to the Aerami website following the meeting.

AER-901, a proprietary liquid formulation of imatinib for inhalation delivered by a breath activated, high-performance, handheld, smart nebulizer, is in development to address the unmet medical need for people with serious and rare forms of pulmonary hypertension, including the lead indication, pulmonary hypertension associated with interstitial lung disease (PH-ILD), as well as pulmonary arterial hypertension (PAH). In animal models of pulmonary hypertension, imatinib reversed the proliferative, fibrotic, and inflammatory pulmonary vascular remodeling process that is believed to drive symptom severity, disease progression, and outcomes in many forms of the disease. In a Phase 3 clinical trial sponsored by Novartis, oral imatinib demonstrated substantial efficacy when added to 2 or 3 background standard-of-care medications for PAH. However, the efficacious oral doses were poorly tolerated with an unacceptable safety profile. By targeting administration of AER-901 directly to the lung, nonclinical data suggest that an approximate 10-fold dose reduction relative to oral imatinib is appropriate.

Clinical data presented at the 2023 ERS International Congress include safety, tolerability, and pharmacokinetic results from the AER-901 Phase 1 trial. The trial enrolled 84 healthy volunteers and included single ascending dose and multiple ascending dose studies, as well as a cross-over study that compared AER-901 with oral imatinib. Once- and twice-daily dosing with an additional formulation were also evaluated.

Highlights from the presentation include:

  • AER-901 was generally well tolerated with predominantly mild adverse events. Low rates of gastrointestinal and systemic adverse events were observed, likely due to low systemic exposures relative to oral imatinib.
  • AER-901 was absorbed rapidly, consistent with expectations of the liquid formulation of imatinib and Aerami’s nonclinical data.
  • AER-901 demonstrated a distinct absorption profile compared with oral imatinib, suggesting efficient lung deposition and little, if any inadvertent swallowing.

“The data from our Phase 1 clinical trial demonstrate that the AER-901 drug-device combination can efficiently deliver imatinib directly to the lung with a potentially improved systemic safety profile,” said Dr. Gary Burgess, Aerami’s Chief Medical Officer. “These data are consistent with our hypothesis that AER-901 has the potential to achieve efficacy with improved safety and tolerability relative to oral imatinib, and we believe that they strongly support the design of our planned platform Phase 2 trial, uniPHied, which will enroll people with either PH-ILD or PAH.”

About AER-901
AER-901 is a drug-device combination that is designed to efficiently deliver imatinib therapy deep into the diseased tissues of the lung. AER-901 is comprised of a proprietary, liquid formulation of imatinib for inhalation that is administered by a breath-activated, high-performance, handheld, smart nebulizer that controls flow rate and provides real-time feedback to help optimize lung deposition. AER-901 is currently in clinical development for people with PH-ILD and PAH, two rare and serious forms of pulmonary hypertension with high unmet medical need for improved treatment options.

About the uniPHied Trial
The uniPHied trial is a planned Phase 2, placebo-controlled, randomized, parallel group, proof-of-concept platform clinical trial that will evaluate AER-901 in addition to background standard of care therapy. The trial will enroll people with either PH-ILD or PAH into one of 2 cohorts. Participants will then be randomized to receive either AER-901 or placebo administered twice daily via the AER-901 inhalation device. The primary endpoint for each cohort will be the percentage reduction in pulmonary vascular resistance (PVR) following 24 weeks of treatment. Aerami plans to allow all participants who complete the 24-week treatment period to enter a long-term extension study.

About Pulmonary Hypertension Associated with Interstitial Lung Disease (PH-ILD) 
Interstitial lung disease (ILD) is an umbrella term for several conditions that cause inflammation and scarring (fibrosis) of the lung tissue. Pulmonary hypertension is a serious complication of ILD for more than 80,000 people in the United States, Europe, and Japan, and is characterized by high blood pressure in the arteries of the lungs that is believed to be associated with pulmonary vascular remodeling. Pulmonary vascular remodeling is a proliferative, fibrotic, and inflammatory process that leads to narrowing and obstruction of small pulmonary arteries. Over time, pulmonary vascular remodeling is believed to drive increased pulmonary arterial pressure, which causes the heart to work harder as it pumps blood through the lungs, eventually leading to right heart failure. There is only one FDA-approved treatment for PH-ILD, and estimated survival is less than 5 years.

About Pulmonary Arterial Hypertension (PAH) 
PAH is a rare and progressive form of pulmonary hypertension characterized by high blood pressure in the arteries of the lungs due to their narrowing or a blockage. PAH, which disproportionately impacts women and frequently during the middle part of their lives, affects approximately 70,000 people in the United States and Europe. As in PH-ILD, pulmonary vascular remodeling is believed to drive PAH symptoms, disease progression, and outcomes. Currently approved treatments primarily mediate vasodilation, and despite advances in therapy, median survival remains approximately 5-7 years.
