Methods of inhibiting leukotriene A4 hydrolase
View Patent ↗The present invention is directed to methods of inhibiting LTA 4 -h in a human patient and method of treating a condition ameliorated by the inhibition of leukotriene A 4 hydrolase activity in a human patient comprising administering to said human patient the compound, 4-{5-[4-(4-Oxazol-2-yl-phenoxy)-benzyl]-2,5-diaza-bicyclo[2.2.1]hept-2-ylmethyl}-benzoic acid.
1. A method for the treatment of cystic fibrosis comprising inhibiting leukotriene A4 hydrolase activity in a human patient, wherein the method comprises administering to said human patient the compound, 4-{[(1S,4S)-5-({4-[4-oxazol-2-yl-phenoxy]phenyl}methyl)-2,5-diazabicyclo[2.2.1]heptan-2-yl]methyl}benzoic acid, at a dose of about 50 mg or less, wherein the compound is administered orally, wherein the dose achieves a blood plasma level that exceeds or achieves the IC 50 of the compound for at least 12 hours, and wherein the IC 50 is that for leukotriene A4 hydrolase activity inhibition; and wherein the compound is co-administered with at least one additional therapeutic agent and wherein the additional therapeutic agent is an antibiotic, a mucolytic, a pancreatic enzyme replacement drug, or a combination thereof.
2. The method of claim 1 , wherein the compound is administered at a dose between about 1 mg and about 50 mg.
3. The method of claim 2 , wherein the compound is administered at a dose between about 5 mg and about 25 mg.
4. The method of claim 3 , wherein the compound is administered at a dose of about 5 mg.
5. The method of claim 1 , wherein the human patient is a pediatric patient.
6. The method of claim 1 , wherein the dose achieves a blood plasma level that exceeds the IC 50 of the compound for at least 24 hours.
7. The method of claim 1 , wherein the dose is administered at intervals of about 12 to about 24 hours.
8. The method of claim 1 , wherein the compound is administered at a dose of about 10 mg.
