The study also included 13 secondary outcomes...all of which failed to meet their goals....With the disappointing results in hand, Amgen has decided to discontinue the asset in the lung indication. The termination includes an open-label extension of the lung trial."

Pharmacokinetics of Fipaxalparant, a Small-Molecule Selective Negative Allosteric Modulator of Lysophosphatidic Acid Receptor 1, and the Effect of Food in Healthy Volunteers. (PubMed, Clin Pharmacol Drug Dev) - "At 450 mg, a high-fat meal increased the maximum observed concentration and area under the curve by approximately 1.9- and 2.1-fold, respectively. These results, combined with prior preclinical and phase 2a data, informed dose selection of fipaxalparant 300 mg once and twice daily with a meal for phase 2b studies."
