Treatment of diseases associated with hepatic stellate cell activation using ammonia-lowering therapies
View Patent ↗Disclosed herein are methods of preventing, treating, and delaying the onset or progression of diseases associated with hepatic stellate cells (HSCs), such as non-alcoholic fatty liver disease (NAFLD), fibrosis, and liver cancer, using ammonia-lowering therapies.
1. A method of treating or delaying the onset or progression of a disease associated with hepatic stellate cell (HSC) activation, comprising administering an ammonia-lowering agent to a subject in need thereof, wherein the disease associated with HSC activation is non-alcoholic fatty liver disease (NAFLD), liver cancer, or fibrotic condition.
2. The method of claim 1 , wherein the disease associated with HSC activation is non-alcoholic fatty liver disease (NAFLD).
3. The method of claim 2 , wherein the NAFLD is non-alcoholic steatohepatitis (NASH).
4. The method of claim 2 , wherein the NAFLD is steatosis.
5. The method of claim 1 , wherein the disease associated with HSC activation is liver cancer.
6. The method of claim 1 , wherein the disease associated with HSC activation is a fibrotic condition.
7. The method of claim 6 , wherein the fibrotic condition is liver fibrosis.
8. The method of claim 1 , wherein the ammonia-lowering agent comprises a magnesium phosphate product (MGP), glycerol phenylbutyrate (GPB), sodium phenylacetate, sodium phenylbutyrate (NaPBA), glutamine, sodium benzoate, L-arabinose, a laxative, an antibiotic, ornithine in combination with at least one of phenylacetate and phenylbutyrate, or any combination thereof.
9. The method of claim 8 , wherein the ammonia-lowering agent comprises ornithine in combination with at least one of phenylacetate and phenylbutyrate.
10. The method of claim 9 , wherein separate pharmaceutically acceptable salts of the ornithine and at least one of phenylacetate and phenylbutyrate are administered to the subject.
11. The method of claim 10 , wherein at least one of phenylacetate and phenylbutyrate is administered as a sodium phenylacetate or sodium phenylbutyrate.
12. The method of claim 9 , wherein the ornithine is administered as a free monomeric amino acid or physiologically acceptable salt thereof.
13. The method of claim 9 , wherein the ornithine and phenylacetate is administered as ornithine phenylacetate.
14. The method of claim 1 , wherein the administration is oral, intravenous, intraperitoneal, intragastric, or intravascular administration.
15. The method of claim 14 , wherein the administration is intravenous administration.
16. The method of claim 14 , wherein the administration is oral administration.
