What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how safe and effective the antibiotic lefamulin is for treating community-acquired pneumonia (CAP) in Chinese patients. CAP is a lung infection caught outside of hospitals, and many common antibiotics are becoming less effective due to drug resistance. Lefamulin works differently from other antibiotics and may be effective against resistant bacteria. Researchers will track side effects and how well patients recover in real-world medical settings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
lefamulin
What this could lead to
If successful, lefamulin could offer a new, effective antibiotic option for pneumonia, especially against drug-resistant bacteria.
What could go wrong
This is a real-world observational study, not a controlled trial, so results may be less definitive. Antibiotic resistance could still develop over time.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: 1. Signed informed consent form 2. Clinical diagnosis of community-acquired pneumonia (CAP) by treating physicians 3. Currently receiving lefamulin treatment or prescribed and agreed to initiate lefamulin therapy as determined by the treating physician Exclusion Criteria: 1. Patients with contraindications to lefamulin according to the approved prescribing information (e.g., known hypersensitivity to lefamulin or pleuromutilin class antibiotics) 2. Pulmonary infiltrates caused by non-infectious factors (e.g., pulmonary embolism, aspiration chemical pneumonitis, hypersensitivity pneumonitis, congestive heart failure, bronchial obstruction, lung cancer, cystic fibrosis) 3. Confirmed or suspected empyema via chest X-ray or CT examination 4. Participation in any other ongoing interventional clinical trial
