Symprove (Probiotic) as an add-on to COVID-19 Management

May 6, 2021 updated by: King's College Hospital NHS Trust

The Effect of Symprove, a Multi-strain Probiotic, as an Adjuvant in the Management of COVID-19 in Hospitalized Patients

The major impact of COVID-19 has been that the severity of respiratory symptoms require intensive hospital treatment. There is significant mortality and many of the survivors have a delayed recovery requiring intensive prolonged rehabilitation.

COVID-19 is a multi-systemic disease in which different mechanisms within the body are affected; including the 'Gut microbiome'. 'Gut microbiome' refers to the bacteria living in intestines. While some bacteria is harmful, many are extremely beneficial and necessary for a healthy body. Many patients have gastrointestinal symptoms and there is a major change in the gut micro flora (microbiome), which may have an adverse effect on the respiratory symptoms. The probiotic, Sivomix, was given to hospitalized COVID-19 patients was associated with a more rapid recovery in gastrointestinal symptoms on day 3 and 7, and an eight fold reduction in the requirement for mechanical ventilation in an open trial.

This is a randomized clinical trial, with a recruitment target of 60 patients admitted with COVID-19 symptoms to the general medical wards. Patients will be randomized to receive the probiotic, Symprove, or placebo in addition to their standard of care treatment. Patients will need take either probiotic/placebo daily for 3 months. All follow-up will be whilst they are an inpatient or as a telephone follow-up; they will not need to attend at the hospital to participate.

There is a biological sub-study incorporated into the protocol, but participation is optional. If patients consent to this, they will also need to provide blood, faecal and saliva samples at baseline, Day 7 and final visit (3 months after randomisation). Patients who consent to providing biological samples will need to visit the hospital at Day 7 and final visit.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Enrollment (Anticipated)

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.
60

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Symptomatic patients who are hospitalised with respiratory COVID-19
  • Ability to give informed consent
  • Aged 20-85

Exclusion Criteria:

  • Patients not meeting the inclusion criteria that have COVID-19
  • Inability to consent
  • Pregnancy
  • Severe pre-existing mental health disorders or addictions

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Symprove

Other: Symprove (probiotic)
Symprove's unique water-based formula is packed full of live, active bacteria. It is a probiotic, not a drug.
Placebo Comparator: Placebo
Matched placebo provided by Symprove. Identical in appearance to Symprove probiotic.
Other: Placebo
Matched placebo to Symprove probiotic

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
Length of hospital stay
Time Frame: 12 months
To assess if taking the probiotic Symprove reduces the length of hospital stay of patients with symptomatic respiratory COVID-19 infection
12 months

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
Clinical symptoms
Time Frame: 7 days
Whether administration of Symprove is associated with significantly greater improvements in clinical symptoms as opposed to placebo on day 3 and 7.
7 days
Intestinal inflammation
Time Frame: 3 months
Whether Symprove reduced intestinal inflammation as compared with that seen in placebo are improved (at day 7 and 3 months).
