Overview

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.

Detailed description

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.

Interventions

Drug Contezolid
Contezolid 800mg once daily (QD) for 7 days;
Drug Linezolid (LZD)
Linezolid 600mg once daily (QD) for 7 days.

Primary outcome measures

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]

Eligibility criteria

Inclusion criteria

(1) Inpatients who have been diagnosed with or clinically diagnosed with tuberculous meningitis within the past 3 months prior to screening; (2) Voluntarily participate in this study and sign the informed consent form; (3) Male and female participants must use effective contraception during the study and for 1 month after the study ends.

Exclusion criteria

(1) Patients who have been on long-term corticosteroid therapy or taking immunosuppressants within 90 days prior to screening; (2) Pregnant women, patients in the puerperium, and lactating women; (3) Patients with a history of allergy or known hypersensitivity to contezolid or linezolid, or a history of severe adverse reactions; (4) Patients with evidence of resistance to contezolid or linezolid; (5) Patients deemed unsuitable for participation in this study by the investigator's assessment; (6) Patients whom the investigator believes participation in this study would harm their health, or who are deemed unable to comply with the scheduled visits and assessments as outlined in the protocol, and therefore unsuitable for participation in this study.
