Methods for treating ulcerative colitis
The present disclosure provides methods and treatment regimens for treating ulcerative colitis in a subject in need thereof. In particular, the methods described herein comprise treating a subject in need thereof with a treatment regimen comprising the administration of a pharmaceutical composition comprising live non-pathogenic fecal bacteria for at least 8 weeks and at least three times per week. In an aspect, the subject in need thereof exhibits a Mayo endoscopy score of 3 or lower. In some aspects, the subject in need thereof has no concomitant corticosteroid use during said method and has no corticosteroid use immediately prior to commencing said method.
1. A pharmaceutical composition of non-pathogenic bacteria comprising a preparation of viable bacteria, wherein the preparation of viable bacteria comprises (i) a nonselective mixture of non-pathogenic fecal bacteria extracted from a stool of a first human donor having no history or current symptoms of gastrointestinal disease, and (ii) one or more cultured, non-pathogenic bacterial isolates isolated from one or more stools of one or more human donors other than the first human donor, wherein administration of the composition for at least one week and at least twice per week to a patient having colitis is effective at treating the colitis.
2. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member selected from the group consisting of: Clostridium cluster IV, Dorea, Blautia, Ruminococcus, Barnesiella, Parabacteroides , and Clostridium cluster XVIII.
3. The pharmaceutical composition of non-pathogenic bacteria of claim 2 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member of Clostridium cluster IV.
4. The pharmaceutical composition of non-pathogenic bacteria of claim 3 , wherein the member of Clostridium cluster IV is Faecalibacterium prausnitzii.
5. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member of a genus selected from the group consisting of Clostridium, Odoribacter, Alisnpes, Akkermansia, Bacteroides , and Eubacterium.
6. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the preparation of viable bacteria does not include one or more of Fusobacterium and Sutterella.
7. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the preparation of viable bacteria includes neither Fusobacterium nor Sutterella.
8. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the one or more cultured, non-pathogenic bacterial isolates are isolated from stools of multiple human donors.
9. The pharmaceutical composition of non-pathogenic bacteria of claim 1 , wherein the nonselective mixture of non-pathogenic fecal bacteria comprises a substantially complete fecal microbiota from the stool of the human donor.
10. A pharmaceutical composition of non-pathogenic bacteria comprising a preparation of viable fecal bacteria, wherein the preparation of viable fecal bacteria comprises a nonselective mixture of non-pathogenic fecal bacteria extracted from a stool of a first human donor having no history or current symptoms of gastrointestinal disease supplemented with one or more cultured, non-pathogenic bacterial isolates isolated from a stool of a donor other than the first human donor.
11. The pharmaceutical composition of non-pathogenic bacteria of claim 10 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member selected from the group consisting of Clostridium cluster IV, Dorea, Blautia, Ruminococcus, Barnesiella, Parabacteroides , and Clostridium cluster XVIII.
12. The pharmaceutical composition of non-pathogenic bacteria of claim 11 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member of Clostridium cluster IV.
13. The pharmaceutical composition of non-pathogenic bacteria of claim 12 , wherein the member of Clostridium cluster IV is Faecalibacterium prausnitzii.
14. The pharmaceutical composition of non-pathogenic bacteria of claim 10 , wherein the one or more cultured, non-pathogenic bacterial isolates comprise a member of a genus selected from the group consisting of Clostridium, Odoribacter, Alistipes, Akkermansia, Bacteroides , and Eubacterium.
15. The pharmaceutical composition of non-pathogenic bacteria of claim 10 , wherein the preparation of viable bacteria does not include one or more of Fusobacterium and Sutterella.
16. The pharmaceutical composition of non-pathogenic bacteria of claim 10 , wherein the preparation of viable bacteria includes neither Fusobacterium nor Sutterella.
