Group Intervention Description Carrimycin Carrimycin Patients will receive oral dose of 400 mg carrimycin once-daily and SOC for 14 days. Placebo Placebo Patients will receive oral dose of Placebo once-daily and SOC for 14 days.
- Primary Outcome Measures
Name Time Method Time to patient not requiring supplemental oxygen up to 28 days after randomisation Up to Day 28 To evaluate the efficacy of carrimycin with SOC compared to placebo with SOC in patients hospitalized with severe SARS-CoV-2 pneumonia. Patients must have remained off of supplemental oxygen for at least 48 hours and remain off of oxygen until Day 28
- Secondary Outcome Measures
Name Time Method Changes from baseline in sequential organ failure assessment (SOFA) score From baseline (Day -4 to Day -1) Days 3, 7, 10, 14 and 28 after treatment To evaluate the improvement for specific clinical parameters including fever, respiratory rate, oxygen saturation, breathlessness, cough and sputum production. The SOFA score ranges from 0 to 4. Lower score predicts better organ functioning and higher score represents severe organ failure.
Percentage of patients who reach level 2 or lower at Day 28 on the 8 category ordinal scale From screening Day (Day -4 to Day -1) until Day 28 The 8-Category ordinal scale score ranges from 1 to 8. Score 1: Not hospitalized, no limitations on activities; 2: Not hospitalized, limitation on activities, home oxygen requirement or both; 3: Hospitalized, not requiring supplemental oxygen and no longer requiring ongoing medical care; 4: Hospitalized, not requiring supplemental oxygen but requiring ongoing medical care; 5: Hospitalized, requiring supplemental oxygen; 6: Hospitalized, requiring noninvasive ventilation or high flow oxygen devices; 7: Hospitalized, receiving invasive mechanical ventilation or extracorporeal membrane oxygenation and score 8: Death. Higher scores indicate worse outcome.
Mean changes in BCSS score during the study period From screening Day (Day -4 to Day -1) until Day 28 To evaluate the improvement for specific clinical parameters including breathlessness, cough and sputum production. The BCSS is a three-item questionnaire rating breathlessness, cough and sputum on a 5-point Likert scale from 0 (no symptoms) to 4 (severe symptoms). A reduction in the mean total BCSS score represents a substantial symptomatic improvement.
Change from baseline in respiratory rate From screening Day (Day -4 to Day -1) until Day 60 and at Early Withdrawal To evaluate the improvement for specific clinical parameters including respiratory rate.
Number of patients with adverse event (AEs) and Serious adverse events (SAEs) From screening Day (Day -4 to Day -1) until Day 28 and until Day 60 To evaluate the safety and tolerability of the carrimycin and to describe the safety profile of treatments as reflected by AEs and SAEs.
Change from baseline in temperature From screening Day (Day -4 to Day -1) until Day 60 and at Early Withdrawal To evaluate the improvement for specific clinical parameters including fever.
Time to recovery based on 8-category ordinal scale From screening Day (Day -4 to Day -1) until Day 28 To describe the difference in time to pre-defined symptom improvement compared to placebo, based on 8-category ordinal scale. Time to recovery is defined as time point when a patient reaches level 3 or lower on the 8-Category ordinal scale and does not return to a level \> 3 during the 28-day period. The 8-Category ordinal scale score ranges from 1 to 8. Score 1: Not hospitalized, no limitations on activities; 2: Not hospitalized, limitation on activities, home oxygen requirement or both; 3: Hospitalized, not requiring supplemental oxygen and no longer requiring ongoing medical care; 4: Hospitalized, not requiring supplemental oxygen but requiring ongoing medical care; 5: Hospitalized, requiring supplemental oxygen; 6: Hospitalized, requiring noninvasive ventilation or high flow oxygen devices; 7: Hospitalized, receiving invasive mechanical ventilation or extracorporeal membrane oxygenation and score 8: Death. Higher scores indicate worse outcome.
Time to recovery based on the Breathlessness, Cough and Sputum Scale (BCSS) From screening Day (Day -4 to Day -1) until Day 28 To describe the difference in time to pre-defined symptom improvement compared to placebo based on the BCSS. The BCSS is a three-item questionnaire rating breathlessness, cough and sputum on a 5-point Likert scale from 0 (no symptoms) to 4 (severe symptoms). A reduction in the mean total BCSS score represents a substantial symptomatic improvement.
Time to symptom improvement From screening Day (Day -4 to Day -1) until Day 28 To describe the difference in time to pre-defined symptom improvement compared to placebo, based on the BCSS. Time to symptom improvement can be considered when the score of a patient has a reduction of 1 with 2 consecutive ratings on the BCSS. The BCSS is a three-item questionnaire rating breathlessness, cough and sputum on a 5-point Likert scale from 0 (no symptoms) to 4 (severe symptoms). A reduction in the mean total BCSS score represents a substantial symptomatic improvement.
Length of hospital stay (in days) From Screening Day (Day -4 to Day -1) until Day 60 or Early Withdrawal To evaluate length of hospital stay between patients receiving carrimycin vs placebo.
Time to discharge (in days) From screening Day (Day -4 to Day -1) until Day 60 and at Early Withdrawal To evaluate time to discharge between patients receiving carrimycin vs placebo.
Number of patients with all cause mortality at Days 14 and 28 At Days 14 and 28 To evaluate mortality rates between patients receiving carrimycin vs placebo.
