NCT03851250

Brief Summary

This is a multicentre, phase I/II, double-blind, placebo-controlled study of MRx-4DP0004 in participants taking long-term medication for asthma. Participants will take two capsules of MRx-4DP0004 twice daily in addition to their existing asthma medication for 12 weeks. Safety and tolerability and immune modulatory effects of MRx-4DP0004 will be assessed throughout the study.

Outcome Measures

Primary Outcomes (4)

  • Number of participants in each treatment arm experiencing adverse events

    Adverse events will be considered alongside other primary outcome measures for assessment of safety and tolerability.

    Baseline to Day 127

  • Number of clinically relevant adverse changes in clinical laboratory tests in each treatment arm

    Clinically relevant adverse changes clinical laboratory tests will be considered alongside other primary outcome measures for assessment of safety and tolerability. Clinical laboratory tests will include clinical chemistry, haematology and urinalysis.

    Baseline to Day 127

  • Number of clinically relevant adverse changes in vital signs in each treatment arm

    Clinically relevant adverse changes in vital signs will be considered alongside other primary outcome measures for assessment of safety and tolerability. Vital signs assessments will include measurement of systolic blood pressure, diastolic blood pressure, oral body temperature and pulse rate.

    Baseline to Day 127

  • Number of clinically relevant adverse changes in 12-lead ECGs in each treatment arm

    The number of participants experiencing clinically relevant adverse changes in Clinically relevant adverse changes in vital signs will be considered alongside other primary outcome measures for assessment of safety and tolerability. ECG assessments will include measurement of PR, QRS, QT and QTcF.

    Baseline to Day 127

Secondary Outcomes (11)

  • Difference in the mean change in the Asthma Control Questionnaire (ACQ-6) between treatment arms

    Baseline to Day 99

  • Difference in the number of subjects achieving good asthma control (as defined by an ACQ-6 score <1.0) between treatment arms.

    Baseline to Day 99

  • Difference in the number of asthma exacerbations between treatment arms

    Baseline to Day 99

  • Difference in the number of hospitalisations due to asthma exacerbation between treatment arms

    Baseline to Day 99

  • Difference in the change from baseline in Forced Expiratory Volume in 1 second (FEV1) between treatment arms

    Baseline to Day 99

  • +6 more secondary outcomes

Other Outcomes (13)

  • Difference in the change from baseline in faecal microbiota profile between treatment arms

    Baseline to Day 99

  • Difference in the change from baseline in Fraction exhaled nitric oxide (FeNO) between treatment arms

    Baseline to Day 99

  • Difference in the change from baseline in Immunoglobulin E (IgE) between treatment arms

    Baseline to Day 99

  • +10 more other outcomes

Study Arms (2)

MRx-4DP0004

EXPERIMENTAL

MRx-4DP0004 is a Live Biotherapeutic Product containing 10\^9 to 10\^10 Colony Forming Units. Participants randomised to this arm will take 2 capsules twice daily at approximately 12 hour intervals for 12 weeks.

Drug: MRx-4DP0004

Placebo

PLACEBO COMPARATOR

Participants randomised to this arm will take 2 capsules of placebo twice daily at approximately 12 hour intervals for 12 weeks. All participants will receive placebo in a single blind manner for two weeks in addition to the 12 weeks of double blind treatment.

Drug: Placebo

Interventions

Participants randomised to receive MRx-4DP0004 will take it in addition to their regular asthma medication.
