Fecal Microbiota Transplantation

The aim of this study is to assess the Fecal Microbiota Transplantation (FMT) efficacy in the prevention of allogeneic hematopoietic stem cell transplantation (allo-HSCT) complications and particularly Graft versus Host Disease (GvHD). The hypothesis of this study is that allogeneic FMT may improve outcomes of these patients.

This is an open-label, multicenter, randomized controlled Phase II trial. Patients with advanced hepatocellular carcinoma (HCC) who developed secondary resistance to first-line targeted-immunotherapy were randomly assigned to receive either the original first-line targeted-immunotherapy combined with FMT and PULSAR (experimental group), or second-line targeted-immunotherapy (control group). The first-line targeted-immunotherapy regimens consisted of tislelizumab combined with one of the first-line evidence-based tyrosine kinase inhibitors (TKIs), including lenvatinib, donafenib, apatinib, and sorafenib. Given that this study enrolled patients who progressed after an initial response to first-line targeted-immunotherapy, the second-line regimen in the control group continued tislelizumab immunotherapy while switching the TKI to regorafenib, an agent with second-line evidence.

To find out if adding treatment with fecal microbiota transplantation (FMT) is effective at treating gut-related side effects of antibiotic treatment in participants who are receiving standard therapy with anti-CD19 chimeric antigen receptor T-cell (CAR-T cell) therapy.

This trial studies how well fecal microbiota transplantation works in treating diarrhea or colitis (inflammation of the intestines) that is caused by certain types of medications (called immune-checkpoint inhibitors) in patients with genitourinary cancer. Fecal microbiota transplantation may effectively reduce the incidence of immune checkpoint inhibitor-induced diarrhea/colitis.

This trial studies the role of the gut microbiome and effectiveness of a fecal transplant on medication-induced gastrointestinal (GI) complications in patients with melanoma or genitourinary cancer. The gut microbiome (the bacteria and microorganisms that live in the digestive system) may affect whether or not someone develops colitis (inflammation of the intestines) during cancer treatment with immune-checkpoint inhibitor drugs. Studying samples of stool, blood, and tissue from patients with melanoma or genitourinary cancer may help doctors learn more about the effects of treatment on cells, and help doctors understand how well patients respond to treatment. Treatment with fecal transplantation may help to improve diarrhea and colitis symptoms.
