About this study
Contezolid is a novel oxazolidinone antibiotic developed by Shanghai Mengke Pharmaceutical Co., Ltd., which successfully went public in 2021. It inhibits bacterial growth by interfering with protein synthesis through its translational inhibitory effect on bacteria. Contezolid has demonstrated promising clinical results in patients with drug-resistant tuberculosis, making it a powerful tool in the fight against drug-resistant tuberculosis.
Currently, there is a lack of pharmacokinetic data on contezolid in patients with central nervous system tuberculosis. Some studies have reported the steady-state concentrations of contezolid in the serum and cerebrospinal fluid (CSF) of tuberculous meningitis patients receiving multidrug therapy, showing that the concentration of contezolid in the CSF exceeds the minimum inhibitory concentration against Mycobacterium tuberculosis, and the unbound fraction has a high penetration rate.
In summary, as a novel anti-tuberculosis drug, contezolid has significant potential value in the treatment of tuberculous meningitis. The implementation of this project will help further explore the application prospects of contezolid in the treatment of tuberculous meningitis and provide a safer and more effective treatment option for clinical use.

Contezolid has demonstrated promising clinical results in patients with drug-resistant tuberculosis, making it a powerful tool in the fight against drug-resistant tuberculosis.
Strong anti-tuberculosis activity: Contezolid exhibits comparable anti-tuberculosis activity to linezolid both in vitro and in vivo, and even superior intracellular bactericidal activity against Mycobacterium tuberculosis.
High safety: Contezolid significantly reduces the risks of bone marrow suppression toxicity, neurotoxicity, and lactic acidosis compared to linezolid, bringing new hope to patients who cannot continue traditional therapy due to adverse drug reactions.
Broad application prospects: With the further accumulation of clinical data and in-depth research, the application prospects of contezolid in anti-tuberculosis treatment will undoubtedly be broader. Especially for patients who experience severe adverse reactions and cannot continue using linezolid, contezolid provides a new treatment option.

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
After 7 days of oral treatment with contezolid/linezolid, the patients underwent lumbar puncture to obtain cerebrospinal fluid (CSF) samples, and concentration tests were conducted on both blood and CSF samples. (time frame: 7 days). 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 6 Feb 2025; AzTrials last refreshed its copy on 8 Nov 2026.
