Clinical Trial Summary

This international, multicentre, pragmatic, double-blind, placebo-controlled, randomised trial of TxA versus placebo will enrol 3,300 patients throughout Australia and internationally. This is an effectiveness trial - some elements of the trial are deliberately left to the perioperative clinicians' discretion in order to reflect usual practice and maximise generalisability.

Description:

Study Aims: To conduct a large, multicentre clinical trial of tranexamic acid (TxA), an antifibrinolytic drug routinely used to reduce bleeding in cardiac and some orthopaedic surgery, in 3,300 patients undergoing major gastrointestinal (GI) surgery. Our specific aims are to investigate whether TxA:

Aim 1: Reduces surgical site infection ("wound infection"), and other healthcare-associated infections (pneumonia and sepsis).

Aim 2: Reduces red cell transfusion in GI surgery. Aim 3: Reduces a pooled composite of any serious postoperative complications, and so increases "days alive and at home up to 30 days after surgery" (DAH30).

Aim 4: To evaluate the temporal effect of TxA on perioperative immune and inflammatory responses.

Study Hypothesis Prophylactic TxA administration in patients undergoing major GI surgery reduces the incidence of surgical site infection (SSI) after surgery when compared with placebo.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of Surgical Site Infection	defined by the US Centers for Disease Control (CDC)	from surgical incision to 30 days post surgical incision
Secondary	Red cell transfusion	Total units given	from surgical incision to hospital discharge (from index surgery) or 30 days.
Secondary	Other healthcare-associated infections	sepsis, pneumonia, blood stream infection, UTI, etc; all using CDC-guided definitions	from surgical incision to 30 days
Secondary	C-reactive protein	peak	Postoperative Day 3 (three days after surgical incision)
Secondary	Days at home up to 30 days after surgery (DAH30).	Time that patient spends at home in the 30 days following surgery	From surgical incision to 30 days
