A Study for Efficacy and Safety of Live Biotherapeutic MRx4DP0004 to Treat COVID-19

Phase 2
Withdrawn
Conditions
COVID-19
Interventions
Drug: Placebo
Registration Number
NCT04363372
Lead Sponsor
4D pharma plc
Brief Summary

This is a randomised, double-blind, placebo controlled study to evaluate the efficacy and safety of MRx-4DP0004 in patients with COVID-19.

90 hospitalised patients will be enrolled and randomised (2:1) to receive MRx-4DP0004 or placebo for up to 14 days.

MRx-4DP0004 is an immunomodulating Live Biotherapeutic Product (LBP) which is expected to prevent or reduce the hyperinflammatory response to SARS-CoV-2 infection without impairing viral clearance.

PlaceboPlaceboPatients receiving standard of care will also take 2 placebo capsules, twice a day for 14 days.
MRx-4DP0004MRx-4DP0004Patients receiving standard of care will add MRx-4DP0004 to their treatment. MRx-4DP0004 is taken as 2 capsules, twice a day for 14 days. Daily dose is 4 x 10\^9 to 4 x10\^10 colony forming units.
Primary Outcome Measures
NameTimeMethod
Change in mean clinical status score in each treatment armBaseline to Day 42

Clinical status score will be measured using the WHO Ordinal Scale for Clinical Improvement where patients are scored on a scale of 0-8 with 0 being uninfected and 8 being dead

Secondary Outcome Measures
NameTimeMethod
Time to patients with at least 95% oxygen saturation on room air in each treatment armDay 1 to Day 14

Oxygen saturation will be recorded daily during hospitalisation to determine the mean time for each arm to reach at least 95% saturation

Number of adverse events in each treatment armBaseline to Day 42

Safety and tolerability will be determined according to clinically relevant reported adverse events

Number of patients with an improvement in clinical status score in each treatment armDay 1 to Day 42

Point changes in clinical status score will be measured using the WHO Ordinal Scale for Clinical Improvement

Number of patients with a deterioration in clinical status score in each treatment armDay 1 to Day 42

Point changes in clinical status score will be measured using the WHO Ordinal Scale for Clinical Improvement

Number of patients with at least 95% oxygen saturation on room air in each treatment armDay 1 to Day 14

Oxygen saturation will be measured as per local standard procedures

Number of patients with an improvement in the National Early Warning Score (NEWS) 2 in each treatment armDay 1 to Day 14

The NEWS 2 is based on aggregate scoring of physiological measurements including respiration rate, oxygen saturation, systolic blood pressure, pulse rate, level of consciousness and temperature

Number of patients with an deterioration in the National Early Warning Score (NEWS) 2 in each treatment armDay 1 to Day 14

The NEWS 2 is based on aggregate scoring of physiological measurements including respiration rate, oxygen saturation, systolic blood pressure, pulse rate, level of consciousness and temperature

Number of patients requiring Continuous Positive Airway Pressure in each treatment armDay 1 to Day 14

Details of required respiratory support will be recorded throughout hospitalisation

Number of patients requiring Intermittent Positive Pressure Ventilation in each treatment armDay 1 to Day 14

Details of required respiratory support will be recorded throughout the treatment period

Time to patients requiring Continuous Positive Airway Pressure in each treatment armDay 1 to Day 14

Details of required respiratory support will be recorded throughout the treatment period

Time to patients requiring Intermittent Positive Pressure Ventilation in each treatment armDay 1 to Day 14

Details of required respiratory support will be recorded throughout the treatment period

Time to discharge in each treatment armDay 1 to Day 42

Length of hospital stay will be compared

Number of deaths in each treatment armDay 1 to Day 42

All cause mortality will be compared
