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

It is scientifically recognised that some probiotic effects can be obtained from inactivated bacteria or isolated bacterial components (e.g. bacterial DNA) or factors produced during fermentation (short-chain fatty acids, bacterial proteins, etc.) (7). This category also includes the ingredient which forms the focus of this trial: fermented rice flour, prepared from rice flour fermented by a probiotic (Lactobacillus paracasei CBA L74) which was heat-inactivated at the end of the fermentation process. The finished product, therefore, does not contain live bacteria.

The bacterium used - owned by the sponsor and filed with the BCCM/LMG bacteria collection - belongs to the species Lactobacillus paracasei, and is included in the Qualified Presumption of Safety (QPS) list of microorganisms compiled by the European Food Safety Authority's Panel on Biological Hazards (8). The bacterium has been tested for its sensitivity to antibiotics on the basis of the relevant criteria drawn up by the EFSA (9) and its genomic sequence is known. Pre-clinical studies have shown anti-inflammatory effects of food matrices fermented with Lactobacillus paracasei CBA L74 (stimulating the production of IL-10 and the reduction of IL-12), and in response to stimulation with Salmonella typhimurium (10). Recently, the clinical effects of the consumption of rice flour fermented with Lactobacillus paracasei CBA L74 for 12 weeks were tested in a pilot study conducted on children with moderate/severe AD (defined using the SCORAD index) (11). In this study, all the children reported an improvement in the severity of the AD and reduced topical steroid application frequency.

Considering the rationale for the use of live or inactivated probiotics or isolated bacterial components for the treatment of AD as well as the clinical studies in the paediatric population that have shown encouraging results (11), this randomised, double-blind, placebo-controlled trial aims to evaluate the efficacy of rice flour fermented with Lactobacillus paracasei CBA L74 in subjects with AD; in particular, this trial will evaluate the clinical response in terms of the severity of the AD during and at the end of a 12-week treatment period and four weeks after the suspension of the treatment.

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.

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.
Outcome Measure
Measure Description
Time Frame

Time Frame: 16 weeks

Standardised questionnaire for calculating the SCORAD score:

Evaluate the efficacy of the administration of fermented rice flour (7 g/day) on the clinical course of patients with moderate or severe Atopic Dermatitis, in terms of a reduction in the SCORAD score, during the study period and four weeks after the suspension of the treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
