Method for reducing the likelihood of developing bladder or colorectal cancer in an individual human being
View Patent ↗A method for treating an individual suffering from one of bladder cancer and colorectal cancer employs a CRISPR system to selectively kill or reduce the numbers of pathogenic bacteria within the individual and the individual is then administered an immune checkpoint inhibitor. In particular embodiments, the pathogenic bacteria is one of E. coli, Pseudomonas aeruginosa and Klebsiella bacteria, and the checkpoint inhibitor is selected from the group consisting of nivolumab, pembrolizumab, pidilizumab, AMP-224, AMP-514, STI-A1110, TSR-042, RG-7446, BMS-936559, MEDI-4736, MSB-0020718C, AUR-012 and STI-A1010. Further embodiments include enhancing the growth of a second bacteria in the individual, such bacteria including Akkermansia, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Fusobacterium, Lactobacillus, Propionibacterium, Ruminococcus, Veillonella, Prevotella, Escherichia and Streptococcus . Still other embodiments include increasing the levels of Roseburia and/or Faecalibacterium prausnitzii , in the individual's gut microbiome.

The method of claim 1 , further comprising enhancing the growth of a beneficial bacteria in the individual selected from the group consisting of Akkermansia, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Fusobacterium, Coprococcus, Lactobacillus, Propionibacterium, Ruminococcus, Veillonella, Prevotella , and Streptococcus bacteria.
3. The method as set forth in claim 1 , wherein a CRISPR-Cas or Cpf1 system is used to cut a gene expressed by the pathogenic bacteria.
4. A method for treating an individual suffering from one of bladder cancer and colorectal cancer, comprising, using a clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR associated protein (Cas) system or a CRISPR from Prevotella and Francisella 1 (Cpf1), selectively killing pathogenic bacteria within the individual, and administering to the individual an immune checkpoint inhibitor that specifically binds to an immune checkpoint protein selected from the group consisting of CTLA4, PD-1, PD-L1, PD-L2, A2AR, B7-H3, B7-H4, BTLA, KIR, LAG3, TIM-3 and VISTA.
5. The method as set forth in claim 4 , wherein the immune checkpoint inhibitor is selected from the group consisting of nivolumab, pembrolizumab, pidilizumab, AMP-224, AMP-514, STI-A1110, TSR-042, RG-7446, BMS-936559, MEDI-4736, MSB-0020718C, AUR-012 and STI-A1010.
6. The method as set forth in claim 4 , wherein a CRISPR-Cas or Cpf1 system is used to cut a gene expressed by the pathogenic bacteria.
7. The method as set forth in claim 4 , wherein the CRISPR-Cas or Cpf1 system is used to insert genes that have controllable elements such that the pathogenic bacteria cells are killed by triggering the expression of said inserted genes.
8. The method as set forth in claim 4 , wherein said pathogenic bacteria are selected from the group consisting of: Staphylococcus aureus; Pseudomonas aeruginosa; Klebsiella; Streptoccocus; Salmonella; Shigella; Mycobacterium tuberculosis; Enterococcus; E coli; Clostridium; Neisseria gonnorrhoea; Acinetobacter baumannii ; and Campylobacter.
9. The method as set forth in claim 4 , wherein CRISPR-Cas or Cpf1 is used to facilitate RNA-guided site-specific DNA cleavage to kill the pathogenic bacteria.
10. The method as set forth in claim 4 , wherein using CRISPR-Cas systems, said pathogenic bacteria are killed while sparing other commensal bacteria.
11. The method of claim 4 , further comprising enhancing the growth of a beneficial bacteria in the individual selected from the group consisting of Akkermansia, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Fusobacterium, Lactobacillus, Propionibacterium, Ruminococcus, Veillonella, Prevotella , and Streptococcus bacteria.
12. A method for treating an individual suffering from one of bladder cancer and colorectal cancer, comprising,
providing in the gut of an individual a population of beneficial bacteria selected from the group consisting of Lactobacillus species;
administering at least 6 grams per day of fiber to the individual to maintain a therapeutically effective amount of the beneficial bacteria in the gut of the individual human being;
increasing the levels of at least one of Faecalibacterium prausnitzii, Bifidobacterium, Lachnospira, Veillonella, Coprococcus, Akkermansia muciniphila and Rothia in the individual's gut microbiome,
administering to the individual an immune checkpoint inhibitor, and, using a clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR associated protein (Cas) system or a CRISPR from Prevotella and Francisella 1(Cpf1) system, reducing the population of a second bacteria in the individual, said second bacteria selected from the group consisting of Staphylococcus aureus; Pseudomonas aeruginosa ; Klebsiella; Streptoccocus; Salmonella; Shigella; Mycobacterium tuberculosis; Enterococcus; Escherichia coli; Clostridium; Neisseria gonnorrhoea; Acinetobacter baumannii ; and Campylobacter.
