Admilparant is an investigational new drug being developed by Bristol-Myers Squibb for the treatment of idiopathic pulmonary fibrosis (IPF) and progressive pulmonary fibrosis (PPF). It is a first-in-class lysophosphatidic acid receptor 1 (LPA1) antagonist.^[1][2]

As of 2024, admilparant is in Phase III clinical trials for both IPF and PPF.^[2][3]
