Trial Identification

Brief Title: Washed Microbiota Transplantation for The Treatment of Oncotherapy-Related Intestinal Complications

Official Title: Efficacy and Safety of Washed Microbiota Transplantation for The Treatment of Oncotherapy-Related Intestinal Complications

Study ID: NCT04721041

Study Description

Brief Summary: Gut microbiota, known as "unrecognized organs", is closely related to the occurrence and development of tumors. Cancer is thought to occur secondary to local chronic inflammation. And some bacteria, such as Helicobacter pylori, also have direct genotoxicity, changing intracellular signaling pathways and thus causing abnormal cell growth. Systemic intestinal dysbiosis may lead to cancer, and fecal microbiota transplantation (FMT) can be a new weapon in anti-cancer treatment.Washed microbiota transplantation (WMT), a new stage of FMT, is based on the automatic microfiltration machine (GenFMTer, Nanjing, China) and the following repeated centrifugation plus suspension with support from specific facilities. The investigators conducted a prospective, one-arm, open-label study on the efficacy and safety of WMT in the treatment of oncotherapy-related complications. This study aimed to exploring the therapeutic potential of WMT in the treatment of oncotherapy-related intestinal complications and improving the quality of life of patients.

Detailed Description: Gut microbiota, known as "unrecognized organs", is closely related to the occurrence and development of tumors. Cancer is thought to occur secondary to local chronic inflammation. And some bacteria, such as Helicobacter pylori, also have direct genotoxicity, changing intracellular signaling pathways and thus causing abnormal cell growth. Systemic intestinal dysbiosis may lead to cancer, and fecal microbiota transplantation (FMT) can be a new weapon in anti-cancer treatment. The reduction of intestinal flora diversity may lead to intestinal dysbiosis, thereby reducing the body immunity and promoting the formation and development of neoplasm. It has been reported that FMT can be used to treat melanoma, liver cancer and prostate cancer after immunotherapy failed. But the mechanism of gut microbiota on the tumor itself remains to be further explored. In 2019, an Italian study reports the efficacy of FMT for diarrhea induced by tyrosine kinase inhibitors in the treatment of renal cell carcinoma, suggesting the therapeutic potential of gut microbiota for tumor-related gastrointestinal complications \[1\]. Fecal Microbiota transplantation (FMT), the most classic way to treat diseases using gut microbiota \[2\], refers to the transplantation of functional microbiota in the feces of healthy people into the intestines of patients. It can reconstruct the overall gut microbiota of patients, thus treating gastrointestinal diseases and external gastrointestinal diseases of patients. In 2013, FMT was for the first time coined into the treatment guidelines on recurrent CDI, and now it plays an important role as a key treatment for clostridium difficile infection \[3\]. Washed microbiota transplantation (WMT), a new stage of FMT, is based on the automatic microfiltration machine (GenFMTer, Nanjing, China) and the following repeated centrifugation plus suspension with support from specific facilities. Compared with manual FMT, WMT can reduce the rate of adverse events (such as fever, diarrhea, abdominal pain, abdominal distension, nausea and vomiting, etc.) without affecting the efficacy. In addition, Zhang et al. have proved that WMT is better than the manual preparation of FMT in improving safety, enriching the precise amount of microbiota and quality controllable in practice \[4\]. In December 2019, A panel of 28 experts from 22 hospitals or institutes in 15 cities has contributed to the "Nanjing consensus on methodology of washed microbiota transplantation" according to the international standards, and the consensus is published in Chinese Medical Journal in July 2020 \[5\]. Therefore, the investigators conducted a prospective, one-arm, open-label study on the efficacy and safety of WMT in the treatment of oncotherapy-related intestinal complications. This study aimed to exploring the therapeutic potential of WMT in the treatment of oncotherapy-related intestinal complications and improving the quality of life of patients.
