Brief Summary:
A study to evaluate the effectiveness of oral doses of Blautix in adult subjects with irritable bowel syndrome (IBS)

Condition or disease Intervention/treatment Phase
Irritable Bowel Syndrome Biological: MRx1234 [Blautia Hydrogenotrophica] Other: Placebo Phase 2

Detailed Description:

500 subjects will be enrolled with a diagnosis of IBS as defined by Rome IV criteria will be classified into cohorts according to the Rome IV classification of IBS subtypes.

Each cohort (Cohort C & Cohort D) will recruit 250 subjects who will randomly receive either Blautix or matching placebo in a 1:1 ratio overall of treated to control subjects.

Subjects will undergo five visits in total across approximately 13 weeks. During the study treatment phase subjects will be asked to complete a variety of Quality of Life questionnaires at certain time points. These will consist of Abdominal Pain Intensity Score, IBS-SSS, IBS-QoL, HADS, Stool frequency, Stool consistency & FFQ.

Subjects will be required to produce relevant blood, urine and faecal samples at pre-determined timepoints from screening through to End of Treatment & follow up visits.

Primary Outcome Measures :
  1. The number of patients who demonstrate more or equal to 50% improvement in their cohort specific symptoms as measured by responses to Abdominal Pain Intensity Scale, Stool Frequency and Stool Consistency questionnaires [ Time Frame: Baseline to EOT up to a maximum of 8 weeks, two treatment cycles (one cycle = 28 days) ]
    Patients will be assessed as overall responders, if they have reported an improvement in their weekly (cohort specific) symptoms for > or equal to 50% of the treatment period. The abdominal pain intensity scale is measured on an11-point Numeric Rating Scale ranging from 0 (none) to 10 (worst possible pain)


Secondary Outcome Measures :
  1. The number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: Baseline to EOT up to a maximum of 8 weeks, two treatment cycles (one cycle = 28 days) ]
    To review incidence, nature, severity, relatedness, expectedness and outcome of adverse events. Haematology and blood chemistry assessments and vital signs


Other Outcome Measures:
  1. Review how the study drug affects and interacts with the body [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    To look at the faecal microbiota profiles and urine and faecal metabolite profiles to see if either show any correlation to the amelioration of IBS-symptoms during treatment with Blautix

  2. How effective is daily doses of Blautix by review of completed QoL and PRO questionnaires [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    review of completed responses to Subject Global Assessment of relief compared from Baseline to FUp as measured on a 5-point Likert scale with the following options Completely relieved, considerably relieved, somewhat relieved; unchanged; worse. Patients will be specifying their level of agreement or disagreement on a symmetric agree-disagree scale for a series of questions

  3. How effective is daily doses of Blautix by review of completed QoL and PRO questionnaires [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    Review of responses to the Stool Consistency and frequency measured on the Bristol Stool Chart for stool types

  4. How effective is daily doses of Blautix by review of completed QoL and PRO questionnaires [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    review of responses to the Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) from Baseline to FUp. The IBS-SSS is measured on a Visual Analog Scale (VAS scale) in combination with reported numeric values which equates to an overall score. Q1-4 are severity scoring and Q5-7clinical assessment. Reponses are totalled for Q1-4 (pts indicate on the vas scale from 0-100 ow much they agree with the statements asked o produce an overall score which is then used to categorize patients as no symptoms, mild, moderate or severe. The category thresholds are as follows '0 = no symptoms, 75-175 = mild symptoms, 176-300 moderate symptoms and more than 300 is severe symptoms

  5. How effective is daily doses of Blautix by review of completed QoL and PRO questionnaires [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    review of responses to the Irritable Bowel Symptom Quality of Life (IBS-QOL) questionnaire from baseline to FUp. This is measured across 34 questions with a 5 point response. Each of the 34 questions will contain 5 possible responses 1:not at all, 2: slightly 3:moderately, 4:quite a bit & 5:extremely. Depending on the response to each of these five question , theses are calculated togather for an overall score. Depending on the question the scale of questions

  6. How effective is daily doses of Blautix by review of completed QoL and PRO questionnaires [ Time Frame: Baseline to Follow Up visit up to a maximum of 16 weeks, two treatment cycles (one cycle = 28 days) ]
    review of responses to the Health Anxiety and Depression Scale from baseline to FUP. Each item is scored from 0-3. A subject can score 0 to 21 for either anxiety or depression depression"
