What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of Erythrocyte Volume Fraction(Percentage of Erythrocyte Volume in Total Volume of Blood)

    Erythrocyte volume fraction means under certain conditions, after centrifugation pressing, the percentage of erythrocyte volume in the total volume of blood

    Measured: baseline to TOC(test of cure), for up to 4 weeks

  2. Change in Creatinine Clearance

    Measured: baseline to TOC(test of cure), for up to 4 weeks

  3. Change in Serum Total Creatine Phosphokinase (CPK)

    Measured: baseline to TOC(test of cure), for up to 4 weeks

  4. Change in Urine pH

    Measured: baseline to TOC(test of cure), for up to 4 weeks

  5. Shift in ECG

    percentage of patients who were primarily tested as normal ECG at baseline and changed into abnormal ECG at TOC visit in all the patients with normal ECG at baseline

    Measured: baseline to TOC(test of cure), for up to 4 weeks

Secondary outcomes (7)
  1. Blinded Investigator's Assessement of Clinical Response at TOC(Test of Cure)

    The percentage of patients who were cured or clinically improved in the clinical evaluable (CE) population of each arm at TOC visit was analyzed. CE population includes all the patients with no significant deviation from study protocol in full analysis set population, and meetting the following specific criteria: 1.receiving randomly dispensed study treatment at appropriate time(with a compliance of at least 80% or 4 days [3 days for patients evaluated as treatment failure]). 2.without the administration of potentially confounding non-investigational antibiotics (using one potentially effective non-investigational antibiotic for the treatment of primary infection due to other reasons than lack of efficacy from Day 1 to TOC [for systemicadministration of non-glycopeptides, >1 calendar day]). 3.meeting the study inclusion/exclusion criteria 4.necessary clinical evaluation performed (evaluation for effectiveness at TOC visit, except for the condition confirmed as clinically ineffective)

    Measured: baseline and TOC, for up to 4 weeks

  2. Blinded Investigator's Assessement of Clinical Response at EOT(End of Therapy)

    The percentage of patients who were cured or clinically improved in the clinical evaluable (CE) population at EOT visit was analyzed. CE population includes all the patients with no significant deviation from study protocol in full analysis set population, and meetting the following specific criteria: 1.receiving randomly dispensed study treatment at appropriate time(with a compliance of at least 80% or 4 days [3 days for patients evaluated as treatment failure]). 2.without the administration of potentially confounding non-investigational antibiotics (using one potentially effective non-investigational antibiotic for the treatment of primary infection due to other reasons than lack of efficacy from Day 1 to TOC [for systemicadministration of non-glycopeptides, >1 calendar day]). 3.meeting the study inclusion/exclusion criteria 4.necessary clinical evaluation performed (evaluation for effectiveness at TOC visit, except for the condition confirmed as clinically ineffective)

    Measured: baseline and EOT(end of therapy), for up to 2 weeks

  3. Microbiological Response at TOC(Test of Cure)

    The microbiological response rate (removal or presumed removal) in ME(microbiological evaluable) population of daptomycin group and comparator group at TOC visit was analyzed. ME population includes all the patients with Gram-positive pathogenic bacteria isolated at baseline in CE population. Microbiological response rate means the percentage of strains which were removed or presumably removed at TOC visit in all the strains isolated from ME population at baseline.

    Measured: baseline and TOC, for up to 4 weeks

  4. Microbiological Response at EOT(End of Therapy)

    The microbiological response rate (removal or presumed removal) in ME(microbiological evaluable) population of daptomycin group and comparator group at EOT visit was analyzed. ME population includes all the patients with Gram-positive pathogenic bacteria isolated at baseline in CE population. Microbiological response rate means the percentage of strains which were removed or presumably removed at EOT visit in all the strains isolated from ME population at baseline.

    Measured: baseline and EOT, for up to 2 weeks

  5. Per-pathogen(Methicillin Resistant Staphylococcus Aureus) Clinical Response at TOC(Test of Cure)

    This is the comparison of clinical efficacy by methicillin resistant staphylococcus aureus(MRSA) between the two groups. As the analysis was performed by specific pathogen in ME population and clinical efficacy was compared meanwhile, the clinical evaluation was based on the number of cases under the category of specific pathogen rather than the number of strains. Percentage of patients who were cured or improved at TOC visit in the patients who were identified with MRSA infection at baseline of both groups.

    Measured: baseline and TOC, for up to 4 weeks

  6. Per-pathogen(Methicillin Sensitive Staphylococcus Aureus) Clinical Response at TOC

    This is the comparison of clinical efficacy by methicillin sensitive staphylococcus aureus(MSSA) between the two groups. As the analysis was performed by specific pathogen in ME population and clinical efficacy was compared meanwhile, the clinical evaluation was based on the number of cases under the category of specific pathogen rather than the number of strains. Percentage of patients who were cured or improved at TOC visit in the patients who were identified with MSSA infection at baseline of both groups.

    Measured: baseline and TOC(test of cure), for up to 4 weeks

  7. Per-pathogen(Staphylococcus Aureus) Microbiological Response at TOC

    This is the comparison of clinical efficacy by staphylococcus aureus between the two groups. As the analysis was performed by specific pathogen in ME population and clinical efficacy was compared meanwhile, the clinical evaluation was based on the number of cases under the category of specific pathogen rather than the number of strains. Percentage of patients who were cured or improved at TOC visit in the patients who were identified with staphylococcus aureus infection at baseline of both groups.

    Measured: baseline and TOC(test of cure), for up to 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Daptomycin and Vancomycin in people with Skin Diseases and Infectious, run by AstraZeneca at 13 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Mar 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change of Erythrocyte Volume Fraction(Percentage of Erythrocyte Volume in Total Volume of Blood) (time frame: baseline to TOC(test of cure), for up to 4 weeks). The study lists 5 primary outcomes in all. 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 9 Mar 2015.
