1. Innovative Combination Therapy with Dendritic Cell Vaccination and Fecal Microbial Transplant for Enhanced Cancer Treatment
H. LEE MOFFITT CANCER CENTER AND RESEARCH INSTITUTE, INC., 2023
Combination therapy for cancer that combines dendritic cell vaccination with fecal microbial transplant (FMT) from pathologic complete response (pCR) donors.

The inorganic material must have a positive charge to selectively support probiotic biofilm formation.
12. Enhancing Cancer Therapy Efficacy with Gut Bacteria Lysates
The Board of Regents of The University of Texas System, 2023
Using gut bacteria lysates to boost immune response to cancer therapy. The lysates are from specific species of Gram-positive and Gram-negative bacteria that have similar DNA features to gut bacteria. The lysates are combined with a carrier and administered as a pharmaceutical composition. The lysates can be used alone or in combination with other cancer treatments to improve efficacy of immunotherapy and radiation therapy. The lysates may contain bacterial components like CpG DNA and Lipid A that stimulate the immune system when injected into patients.
