SNIPR001 for E. coli Infections in Transplant Patients

This study is testing SNIPR001, a treatment made of genetically modified bacteriophages (viruses that infect bacteria), for people with blood cancers who are having an allogeneic hematopoietic stem cell transplant (a type of bone marrow transplant). You would be eligible if you are 18 or older, have a blood cancer, are planning to have this type of transplant, and will be taking levofloxacin (an antibiotic) to prevent infection. The main goals are to see how safe SNIPR001 is and how well your body tolerates it, as well as to look at early signs of how effective it might be. The study is currently unclear on its recruitment status.

Study design
This is a Phase 1b/2a study, meaning it's an early-stage trial. About 24 participants will be randomly assigned to receive either SNIPR001 or a placebo (an inactive substance) along with their standard antibiotic.
What's involved
Participants will be screened for a specific type of E. coli bacteria before the transplant. They will receive oral doses of SNIPR001 or placebo and will be followed for up to 100 days after their transplant.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 100 days after their allogeneic hematopoietic stem cell transplant.

    1. Incidence and severity of adverse events (AEs), treatment-emergent adverse events (TEAEs), and serious adverse events (SAEs), based on National Cancer Institute Common Terminology Criteria for Adverse Events Version 5 (NCI CTCAE v5.0). AEs involving graft versus host disease (GvHD) will be graded according to the International Bone Marrow Registry Severity Index. 2. Time to neutrophil recovery (defined as the 1st day of ANC ≥0.5x109/L for 3 consecutive days) 3. Incidence of non-relapse mortality (NRM) 4. Incidence of all-cause mortality 5. Incidence of primary graft failure and secondary graft failure 6. Incidence of acute graft versus host disease (aGvHD) 7. Incidence of Clostridioides difficile (C. difficile) diarrhea 8.
