Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A syringe containing 5ml of TauroLock™ solution (Taurolidine 1%-citrate 4%) or placebo (0.9% sodium chloride) will be used as test drug/placebo in this study. Patients will be randomised to receive either test drug or placebo first. 2.5ml of solution will be instilled into the indwelling pleural catheter within 7 days of insertion (immediately following pleural drainage) and repeated 4 weeks later (with the taurolidine-citrate/placebo, whichever they did not receive). TauroLock/placebo will be instilled twice to each patient ie. each patient will receive both TauroLock and placebo 4 weeks apart.

This will be performed by clinical research fellow and documented in medication chart at the time of intervention.

Statistical methods / analysis
Intention to treat and per protocol basis.
Univariate comparison of patient baseline characteristics between study groups will consist of paired t-tests or Mann-Whitney U tests based on normally distributed and non-parametric data respectively, Chi-squared tests or Fisher exact tests for categorical data.
The effects of intervention on the pain score and longitudinal data of VAS scales between two groups will be assessed using Generalised Linear Mixed Models (GLMM) with appropriate model links and adjusting for confounders and other relevant patient characteristics, with results summarised as marginal means and 95% confidence intervals (CI’s).
which might include methods for multiple imputation for missing VAS scores.
The proportion of death and hospitalization and also frequencies of SAE’s and PERSAE’s will be compared using chi square tests or Fisher exact test. Time to death, hospitalization as a result of SAE will be analysed using log rank tests and Co proportional hazards, with hazard ratios and 95 % CI represented.
