Abstract: There is a method of treating or preventing pulmonary arterial hypertension or associated pulmonary arterial hypertension in a patient. The method has the step of systemically administering to the patient a therapeutically effective amount of one or more compounds: (S)-ethyl 8-(2-amino-6-((R)-1-(5-chloro-[1,1?-biphenyl]-2-yl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylate or a pharmaceutically acceptable salt thereof, or (S)-8-(2-amino-6-((R)-1-(5-chloro-[1,1?-biphenyl]-2-yl)-2,2,2-trifluoroeth-oxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid or a pharmaceutically acceptable salt thereof, or a combination of the foregoing. There is also a method of treating or preventing pulmonary arterial hypertension or associated pulmonary arterial hypertension in a patient by systemically administering a therapeutically effective amount of a THP1 inhibitor from about 1 mg/kg/day to about 50 mg/kg/day.

Abstract: There is a method of treating or preventing interstitial lung disease in a patient. The method includes the step of administering to the patient a therapeutically effective amount of the compound of the following formula: or a pharmaceutically acceptable salt thereof.

Abstract: Methods and compositions for treating inflammatory disorders of the lower airways are disclosed herein. In one aspect, a method for treating an inflammatory disorder of lower airways in a human subject in need thereof is disclosed, including administering directly to the lower airways in the human subject an effective amount of anakinra, where the effective amount of anakinra is 0.01 mg to 100 mg per day.

Abstract: The present disclosure is directed to intermediates and salts thereof useful for the preparation of spirocyclic compounds which are inhibitors of tryptophan hydroxylase (TPH), particularly isoform 1 (TPH1). Processes of preparing the intermediates, salts, and TPH inhibitors are also provided.
