描述 | Idiopathic pulmonary fibrosis (IPF) causes irreversible loss of lung function. The lysophosphatidic acid receptor 1 (LPA1) pathway is implicated in IPF etiology. BMS-986020 is a high-affinity LPA1 antagonist under assessment in a phase 2 study in patients with IPF[2]. A BMS-986020 concentration-dependent displacement of [18F]BMT-083133 binding was observed in LPA1+ cells and lung sections. At 0.1 nM of BMS-986020, the percent displacement in healthy mice, bleomycin mice, and IPF lungs was 18%, 24%, and 31%, respectively; and at 10 nM, the percent displacement was 73%, 76%, and 64%, respectively[3]. Patients treated with BMS-986020 (600 mg for 26 weeks) experienced a significantly slower rate of decline in FVC vs placebo. Dose-related elevations in hepatic enzymes were observed in both BMS-986020 treatment groups[2]. |
