Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Efficacy
Statistical methods / analysis
Statistical analysis will be performed using computerised software (Stata MP/16.0, StataCorp, College Station, Texas, USA). Baseline characteristics will be reported as frequencies and percentages, means with standard deviation, or medians and interquartile ranges. Summary statistics to compare baseline characteristics will include t-test, chi square test, and Wilcoxon rank sum test, as dictated by data type. The primary outcome will be reported using multivariable mixed effects linear regression models. Secondary outcomes will be explored using multivariable linear regression models for continuous outcomes and logistic regression models for binary outcomes. No imputation will be performed for missing data. A two-sided p-value <0.05 will be considered significant.

Summary
Brief summary
Current pharmacotherapy options of haemodynamic support in critically ill patients with vasodilatory hypotension are limited. Centhaquine is a novel agent that has a dual action on the sympathetic system and may helped in the management of hypotensive states. We hypothesise that, compared to placebo, centhaquine will be associated with higher stroke volume, higher central venous pressure, higher mean arterial pressure, and lower vasopressor agent use over six hours after initiation of the study infusion. We plan to enrol 18 adult patients.
