Response to Emerging Antimicrobial Resistance With Containment Microbiota Therapy (REACT)

Recruiting now · Phase 2

Conditions studied: Multi-Drug Resistant Organism Colonization

In brief

REACT is a phase two, open-label, randomized, controlled trial of microbiota therapy (MT) to reduce colonization with multi-drug resistant organisms (MDRO). REACT is designed to assess the safety and efficacy of MT administered to subjects colonized with a MDRO. The overarching hypothesis is that MT can reduce MDRO colonization with safety that is comparable to observation.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Be able (or have available a Legal Authorized Representative who is able) to understand and sign a written informed consent document.
• Be at least 18 years old at the time of consent.
• Be able to comply with all study protocol requirements, including able to receive MT as retention enema or via enteral feeding tube and be available for the duration of the study follow up.
• Be colonized with a target MDRO (CRE, VRE, ESBL, MDR Pseudomonas) as detected by bacterial culture of stool or peri-rectal swab (collected in companion APPS facility prevalence sampling protocol).
• Be able to discontinue or complete planned courses of antibiotics, probiotics, and other microbiota restoration therapies by Day -1 and not resume until after Day 28.
• The effects of the MT on the developing human fetus are unknown. For this reason, persons of child-bearing potential (POCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
• Agree to refrain from receptive anal intercourse until the last biological specimen (stool sample or peri-rectal swab) is collected (Day 28).

You may not qualify if…

• Are pregnant, breastfeeding, lactating, or planning a pregnancy during study duration (through 4 weeks after the last dose of investigational product, or MT), if POCBP.
• Have known uncontrolled intercurrent illness(es):
• Symptomatic congestive heart failure
• Acute coronary syndrome
• Cardiac arrhythmia
• Untreated in-situ colorectal cancer
• Toxic megacolon
• Ileus
• Positive stool studies without completion of treatment course (including ova and parasites, Salmonella spp, Shigella, Campylobacter, and other enteropathogens).
• other acute illness that in the opinion of the investigator could affect the safety of the participant or make study data uninterpretable.
• Are on systemic antibiotics for any reason other than treatment of recent MDRO infection or clear anticipated need for antibiotics during the follow up period that cannot be rescheduled (e.g. fluoroquinolone prophylaxis for percutaneous nephrostomy tube exchange, prolonged antibiotic course for endocarditis). Participants must complete the planned antibiotic course by study Day -1.
• Have a compromised immune system, defined as:
• AIDS with CD4+ T-cell count <200 and detectable HIV viral load on most recent assay.
• Absolute neutrophil count (ANC) <1,000 neutrophils / mL on day of enrollment.
• Active malignancy requiring intensive induction chemotherapy, radiotherapy, or biologic treatment within 2 months prior to enrollment.
• History of hematopoietic cell transplantation, either allogeneic or autologous in the last 1 year.
• Have a history of significant food allergy that led to anaphylaxis or hospitalization.
• Have a life expectancy of 24 weeks or less
• Have any condition that, in the opinion of the investigator, might interfere with study objectives or limit compliance with study requirements, including but not limited to:
• Known active intravenous drug or alcohol abuse
• Uncontrolled psychiatric illness
• Social situations (e.g. incarceration)
• Received an interventional agent (drug, device, or procedure) within 28 days prior to enrollment.
