Brief Summary

This is a phase 2 study to evaluate the efficacy and safety of SR1375 in hospitalized adult patients with CAP. Patients will receive SR1375 or placebo for 8 weeks. The study duration for each patient is up to 10 weeks.

Detailed Description

This is a randomized, double-blind and placebo-controlled phase 2 study comparing SR1375 with placebo in adult patients with CAP. It consists of a screening period, a double-blind treatment period, and a post-treatment safety follow-up period. Baseline NIAID-OS 8-point scale score will be checked for eligibility. Around 240 eligible subjects will be recruited and randomized into four arms at 1:1:1:1 ratio to receive SR1375 0.3mg, SR1375 1mg, SR1375 3mg or placebo orally daily for 56 days. Subjects, investigators, all clinical study site staffs, and the Sponsor will remain blinded to treatment assignment during the study. Subjects will receive regular treatments as per his/her condition by investigator. After completion of double-blind treatment period, subjects will continue to complete the safety follow-up for 14 days.

Inclusion Criteria
  • Age ≥ 18 years, male or female
  • Diagnosis of CAP
  • Baseline NIAID-OS 8-point scale score of 5 points and transcutaneous oxygen saturation ≤ 93% without oxygen inhalation or 6 points. (5 points refer to hospitalization with oxygen therapy; 6 points refer to hospitalization with high flow oxygen therapy or non-invasive mechanical ventilation. High oxygen flow refers to ≥ 4 L/min.)
  • With ≥ 1 high risk factors including chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, type 2 diabetes, chronic kidney disease, coronary heart disease, age ≥ 65 years, moderate obesity (body mass index>32.5kg/m2), etc.
  • Participants of women of childbearing potential(WOCBP) and male participants with WOCBP partners must agree to use one or more effective contraceptive methods during the treatment period and until 90 days after the last administration.

Key

Exclusion Criteria
  • Have received or require invasive mechanical ventilation or ECMO within 24 hours.
  • With septic shock requiring vasoactive drugs.
  • Unable to swallow capsules due to consciousness disorders or other reasons.
  • With active tuberculosis, severe asthma, hyperglycemia, hyperosmolality, ketoacidosis or diabetes foot.
  • Have experienced unstable angina, acute myocardial infarction, or stroke within the past 3 months.

Primary Outcome Measures
NameTimeMethod
National Institute of Allergy and Infectious Diseases-Outcome Study (NIAID-OS) 8-point scale scoreUp to Day 28

Change from baseline to Day 28 in NIAID-OS 8 scale score. NIAID-OS 8 scale ranges from 1 point (no hospitalization, no activity restrictions) to 8 points (death). The higher score means the worse outcome.

Secondary Outcome Measures
NameTimeMethod
Proportion of subjects ≥ 2 points improvement in National Institute of Allergy and Infectious Diseases-Outcome Study (NIAID-OS) 8-point scale scoreUp to Day 28

Subject proportion of ≥ 2 points improvement in NIAID-OS 8-point scale at Day 14 and Day 28

National Institute of Allergy and Infectious Diseases-Outcome Study (NIAID-OS) 8-point scale scoreUp to Day 14

Change from baseline to Day 7 and Day 14 in NIAID-OS 8 scale score. NIAID-OS 8 scale ranges from 1 point (no hospitalization, no activity restrictions) to 8 points(death),the higher score means the worse outcome.
