Compositions and method for treating primary sclerosing cholangitis and related disorders
The present disclosure is in the field of pharmaceutical compositions suitable for the treatment of diseases in mammals. The disclosure provides novel compositions comprising non-pathogenic fecal microbes for treating primary sclerosing cholangitis and related diseases. The disclosure also provides methods for treating a subject with the compositions disclosed herein.
1. A method for treating primary sclerosing cholangitis (PSC) in a human subject in need thereof, the method comprising orally administering to the human subject a pharmaceutically active therapeutic composition comprising a non-selected fecal microbiota derived from a stool of a healthy human donor, wherein the human subject is pretreated with an antibiotic, and wherein a level of serum alkaline phosphatase (SAP) in the subject is reduced by at least 4-fold compared to a level of SAP in the human subject prior to the antibiotic pretreatment.
2. The method of claim 1 , wherein the composition is administered at least once per day for at least two days in a week.
3. The method of claim 1 , wherein the composition is administered at least once per day for at least five days in a week.
4. The method of claim 1 , wherein the composition is administered at least once per day for at least two consecutive days.
5. The method of claim 1 , wherein the composition is administered at least once per day for at least five consecutive days.
6. The method of claim 1 , wherein the PSC is selected from the group consisting of: stage 1, stage 2, stage 3, and stage 4 PSC.
7. The method of claim 1 , wherein the composition comprises a cryoprotectant.
8. The method of claim 7 , wherein the cryoprotectant is selected from the group consisting of polyethylene glycol, skim milk, erythritol, arabitol, sorbitol, glucose, fructose, alanine, glycine, proline, sucrose, lactose, ribose, trehalose, dimethyl sulfoxide (DMSO), glycerol, and a combination thereof.
9. The method of claim 8 , wherein the cryoprotectant is trehalose.
10. The method of claim 1 , wherein the composition is in a liquid, frozen, freeze-dried, spray-dried, foam-dried, or powder form.
11. The method of claim 1 , wherein the composition is formulated as a delayed or gradual enteric release form.
12. The method of claim 1 , wherein the composition is formulated as an enteric-coated capsule or an acid-resistant capsule.
13. The method of claim 1 , wherein the method eliminates or reduces one or more symptoms selected from the group consisting of: fatigue, itchiness, jaundice, inflammation of the bile ducts, fever, upper abdominal pain, impairment of bile secretion, easy bruising, greasy and foul-smelling stools, gallstones, bile duct stones, anemia, osteoporosis, cirrhosis of the liver, portal hypertension, ascites, liver failure, and cholangiocarcinoma.
14. The method of claim 1 , wherein the method reduces the level of disease indicators selected from the group consisting of: serum bilirubin, serum aminotransferase, alkaline phosphatase, gamma-glutamyltransferase (GGT), gamma globulin, IgM, serum alkaline phosphatase, and a combination thereof after at least 8 weeks of treatment.
15. The method of claim 1 , wherein the composition is administered at least once daily for at least two weeks.
16. The method of claim 1 , wherein the composition is administered at least twice weekly for at least two weeks.
17. The method of claim 1 , wherein the composition is administered at least twice weekly for at least four weeks.
18. The method of claim 1 , wherein the composition is administered at least twice weekly for at least eight weeks.
19. The method of claim 1 , wherein the antibiotic is selected from the group consisting of rifabutin, clarithromycin, clofazimine, vancomycin, metronidazole, rifampicin, nitroimidazole, chloramphenicol, rifaximin, a rifamycin derivative, rifapentine, rifalazil, bicozamycin, aminoglycoside, gentamycin, neomycin, streptomycin, paromomycin, verdamicin, mutamicin, sisomicin, netilmicin, retymicin, kanamycin, aztreonam, aztreonam macrolide, dirithromycin, roxithromycin, telithromycin, azithromycin, bismuth subsalicylate, fidaxomicin, amikacin, arbekacin, rhodostreptomycin, tobramycin, apramycin, and a combination thereof.
20. The method of claim 19 , wherein the antibiotic is a combination of vancomycin and metronidazole.
