Clinical Trial Summary

The objectives of this study is to exploratory whether vancomycin + delpazolid is more effective to the standard of treatment (vancomycin)/ for hospitalised adults with MRSA bacteraemia.


Description:

The mortality from S aureus bacteremia is higher for MRSA than for methicillin-susceptible S aureus (MSSA), typically at 20% to 25%. The current standard therapy for MRSA bacteremia is vancomycin. Vancomycin has many shortcomings, including poor tissue penetration and slow killing time. Vancomycin has reduced efficacy against MRSA and tended to increase the MIC level (called MIC creep). Addition of Delpazolid to Vancomycin could improve the known drawbacks of Vancomycin alone.

Outcome

Type Measure Description Time frame Safety issue
Other Vancomycin minimum inhibitory concentration (MIC) levels Vancomycin MIC level up to 6 weeks
Other Delpazolid MIC levels Delpazolid MIC level by BMD up to 6 weeks
Other Pharmacokinetics (PK) parameters: Cmax Peak Plasma Concentration (Cmax) up to 6 weeks
Other Pharmacokinetics (PK) parameters: AUC(0-last) the area under the concentration-time curve from dosing (time 0) to the time of the last measured concentration up to 6 weeks
Other Pharmacokinetics (PK) parameters: Half-life Half-life up to 6 weeks
Other Pharmacokinetics (PK) parameters: Tmax time to reach Cmax up to 6 weeks
Other Pharmacokinetics (PK) parameters: Cl Clearance up to 6 weeks
Primary Overall cure rate by Day 14 (composite response rate: clinical improvement plus clearance of bacteremia) 'Overall cure' means that there are no symptoms of infection that existed when enrolled in the clinical trial, there are no new metastatic infection due to MRSA and no new infection (clinical improvement), and MRSA negative is confirmed twice in a row as a result of blood culture tests ( clearance of bacteremia).
a. If negative in the blood culture test is confirmed for the first time, additional test will be performed the next day, and if it results negative for a total of two times in a row, it is judged as 'clearance of bacteremia'.
by Day 14
Secondary Overall cure rate by End of Treatment (EOT) composite response rate: clinical improvement plus clearance of bacteremia by EOT visit (up to 6 weeks)
Secondary Mortality due to MRSA bacteremia Proportion of subjects who died due to MRSA bacteremia by Test of Cure (TOC) (=4 weeks after EOT (up to 6 weeks))
Secondary Microbiological relapse rate Defined as a positive blood culture to MRSA when previous ones were negative by TOC (=4 weeks after EOT)
Secondary Clearance of MRSA bacteremia rate Proportion of subjects who confirmed MRSA negative two consecutive set in the blood culture test Day 3, Day 5, Day 7, Day 14, EOT (up to 6 weeks)
Secondary Persistent MRSA bacteremia rate Proportion of subjects who have positive results on blood culture tests Day 3, Day 5, Day 7, Day 14
Secondary Time to clearance of MRSA bacteremia If negative in the blood culture test is confirmed for the first time, additional test will be performed the next day, and if it results negative for a total of two times in a row, it is judged as clearance of bacteremia. The period until the clearance of bacteremia is defined as the period (day) from the date of the first blood culture test within 72 hours prior to randomization with MRSA positive (index blood culture) to the date of the blood culture test with the first negative result confirmed. by EOT (up to 6 weeks)
