Foresee Pharmaceuticals Announces First Patient Dosed in the Phase 2 WINDWARD Study of the ALDH2 Activator Mirivadelgat for Patients with Pulmonary Hypertension-Associated Interstitial Lung Disease (PH-ILD)
  • The WINDWARD study is a multinational, double-blind, 3-arm Phase 2 study to evaluate the safety and efficacy of mirivadelgat in adult subjects with PH-ILD.

  • Mirivadelgat is a first-in-class oral small molecule with a novel mechanism of action, having the potential to provide a disease-modifying treatment for patients with PH-ILD, through its effect on both the cardiovascular and interstitial lung disease components of PH-ILD.

  • PH-ILD is an underserved severe disease. Approximately 30% of ILD patients develop PH, with up to 100,000 diagnosed PH-ILD patients in the U.S.1

TAIPEI, May 15, 2025 /PRNewswire/ -- Foresee Pharmaceuticals (TPEx: 6576), ("Foresee") today announced the dosing of the first patient in the Phase 2 pulmonary hypertension-associated interstitial lung disease (PH-ILD) study (WINDWARD study).

The WINDWARD study is a Phase 2, multinational, double-blind, 3-arm study to evaluate the safety and efficacy of mirivadelgat (FP-045), an oral aldehyde dehydrogenase 2 activator, in adult subjects (aged 18 to 85 years) with PH-ILD.

The WINDWARD Phase 2 study is designed for 16-weeks to evaluate the safety and efficacy of mirivadelgat administered orally compared to placebo in 99 patients (33 evaluable subjects in each cohort) with pulmonary hypertension associated with interstitial lung disease (PH-ILD). The primary endpoint will be the mean change from baseline to week-12 in the Pulmonary Vascular Resistance (PVR) assessed by right heart catheterization for mirivadelgat versus placebo in subjects with PH-ILD. Multiple secondary endpoints will be included, such as the mean change from baseline to week-12 of long-term prognostic risk factors, e.g., N-terminal pro-brain natriuretic peptide (NT-ProBNP) in subjects with PH-ILD and the mean change from baseline to week-12 of the 6-minute walk distance in subjects with PH-ILD.

"Dosing of the first patient in the WINDWARD study is a testament to the dedication of our team to finding a potential therapy for patients with PH-ILD. This trial builds on rigorous foundations and incorporates a robust design to evaluate mirivadelgat 's safety and efficacy across several clinical endpoints, including improvements in Peripheral Vascular Resistance (PVR) and functional capacities in PH-ILD patients. We are committed to executing this study efficiently, generating high-quality evidence, and ensuring patient safety to advance mirivadelgat as a transformative option for patients with Pulmonary Hypertension associated Interstitial Lung Disease (PH-ILD)."
