About this study

Official title: A Randomized, Double-blind, Placebo-controlled Phase II Study to Evaluate the Efficacy and Safety of SR1375 in Hospitalized Adult Patients With Community-acquired Pneumonia

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SR1375 capsule 3mg+regular treatments, SR1375 capsule 1mg+regular treatments and SR1375 capsule 0.3mg+regular treatments in people with Community-acquired Pneumonia, run by Shanghai SIMR Biotechnology Co., Ltd. at 29 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 9 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 29 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wang, PhD ((086)021-68161783, fwang@simrbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

National Institute of Allergy and Infectious Diseases-Outcome Study (NIAID-OS) 8-point scale score (time frame: Up to Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2025; AzTrials last refreshed its copy on 8 Nov 2026.
