About this study
Official title: Efficacy and Safety of Washed Microbiota Transplantation for the Treatment of Oncotherapy-Related Intestinal Complications
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.

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.

Questions about this trial
What is this clinical trial studying?
A study testing Washed Microbiota Transplantation (WMT) in people with Intestinal Complications and Cancer, run by The Second Hospital of Nanjing Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 6 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Faming Zhang, MD,PHD (086-25-58509883, fzhang@njmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Scores of gastrointestinal symptoms (time frame: 8 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04721041, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2025.
