Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This parent-to-child NMT study will test the effect of an anterior nares, or nasal, microbiota transplant (NMT) on seeding, engraftment, and diversity of the neonatal microbiome following nasal decolonization for S. aureus. Infants admitted to the Johns Hopkins Neonatal Intensive Care Unit (NICU) will be screened and parents will be approached for enrollment in the study. After consent and baseline screening of parents and infants, eligible infants will undergo an NMT.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

Yes

Child:

Inclusion criteria

  1. Child has had a prior nasal surveillance culture grow S. aurues
  2. Child is <18 years of age
  3. Child completed treatment with intranasal mupirocin for S. aureus nasal colonization as part of routine clinical care two or more days before the planned transplant
  4. Child has anticipated hospital length of stay >3 days after completing intranasal mupirocin treatment
  5. Infant >25 weeks gestation unless >2 months chronological age

Exclusion criteria

  1. Child is a ward of the State
  2. Child with a diagnosis of immunodeficiency or antenatal suspicion for immunodeficiency (e.g., sibling with known immunodeficiency, genetic syndrome with known associated immunodeficiency)

Donor:

Inclusion criteria

  1. Donor is able to provide informed consent
  2. Donor has a relationship with the child outside of the hospital setting (i.e., not an ICU caregiver)

  4. Donor tests positive on baseline screening test for S. aureus nasal colonization.
  5. Donor tests positive on baseline screening test for a respiratory pathogen.
  6. Donor is not able to provide written informed consent
  7. Donor is not able to be present at the bedside at the time of intervention.
  8. Donor has history of chronic sinusitis, cystic fibrosis, or an infection with a multi-drug resistant organism.
  9. Inability or unwillingness to complete the Donor questionnaire or a positive response to any question on the Donor questionnaire.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
