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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Interventional
Description of intervention(s) / exposure
This is a two- stage study.
Stage 1: Patients will receive STC3141 60 mg/hr as an initial infusion rate which was based on phase Ia study in health volunteer and 60mg/hr is the dosage in long term infusion in phase Ia without aPTT increase, followed by a dose increase of 10 mg/hr every 6 hours until the max infusion rate is 100 mg/hr or the aPTT reaches 1.5 x ULN which ever comes first, then the infusion rate will be fixed in the rest of time. The infusion will continue at this rate for 72 hr.
Stage 2: Arm 1 will receive STC3141 with the initial infusion rate decided from Stage 1 by DSMB, the dosage will be adjusted every 6 hours according to subjects’ aPTT as same as stage 1. The target aPTT and Maximum dosage will be based on DSMB recommendation based on data from stage 1. The infusion last up to 120 hours, unless the patients is well enough to be discharged from ICU, or pass away or experienced intolerable adverse event etc.

Summary
Brief summary
The pathophysiology of ARDS and sepsis involves a dysregulated response of the immune system to infection. NET-associated proteins, particularly histones play very important role and cause significant tissue damage, which correlate highly with death as an outcome.
Our hypothesis is to use STC3141 to neutralize the extracellular histone/NETs.
Continuous infusion STC3141 up to 5 days while the patients are on ventilators in ICU compare to standard care.
