Phase II Clinical Study of Contezolid for the Treatment of Tuberculous Meningitis

Phase 1

• Conditions: Tuberculosis; Meningitis
• Interventions: Drug: Contezolid; Drug: Linezolid (LZD)

• Registration Number: NCT06811025
• Lead Sponsor: Beijing Chest Hospital

Brief Summary

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

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.

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.
