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

The aim of the study is to investigate the efficacy and safety of fecal capsules in the treatment of recurrent Clostridioides difficile infection in a double-blind RCT. The study will also investigate whether stool antigen testing or accurate clinical information on risk factors can identify patients who would benefit most from fecal transplantation. The study will include 76 patients who have had recurrent Clostridioides difficile infection.

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.

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.
76

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Age over 18 years
  • Remission of symptoms during antibiotic course (metronidazole, vancomycin or fidaxomicin)
  • No other antibiotic courses

  • Able to sign the consent form or accept it electronically via Suomi.fi identification

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
Number of patients with recurrence of Clostridioides difficile infection (rCDI), defined as positive fecal Clostridioides difficile nucleinic acid measurement and diarrhea after Fecal Microbiota transplantation (FMT) within 12 weeks after FMT.
Time Frame: The investigators evaluate the number of patietns who get rCDI within 12 weeks after FMT (Placebo or active FMT).
The investigators compare the number of patients with rCDI in different groups (placebo vs active FMT group) evaluated by Clostridioides difficile nucleinic acid measurement.
The investigators evaluate the number of patietns who get rCDI within 12 weeks after FMT (Placebo or active FMT).

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.
Outcome Measure
Measure Description
Time Frame
Number of patients with side effects after FMT capsules.
Time Frame: One, four and twelve weeks after FMT (placebo or active FMT).
Number of patients with side effects after FMT capsules. Number of Safety of FMT capsules is recorded by contacting the patient by phone call after 1 week and by answering the questionnaire after 1, 4 and 12 weeks after FMT (placebo or active FMT). Questionnaire includes information about any symptoms or signs possible related to recurrecy of CDI, such as fever (defined the temperature over 38 degrees), and diarrhea (defindes as more tahn three loose stool per day). Rate of side effects will be expressed by percentage of the patients.
One, four and twelve weeks after FMT (placebo or active FMT).
