Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Colorectal cancer is the second most common cancer in Canada. Colonoscopy and removal of precancerous polyps (polypectomy) reduces the incidence and mortality associated with colorectal cancer. However, polypectomy is associated with adverse events. Post-polypectomy bleeding has a significant impact on the life of the patient as it can require hospitalization, transfusions, repeat colonoscopy and rarely death. It is also a substantial cost to the health care system. There currently is no standard of care to prevent bleeding after polypectomy.

Tranexamic acid reduces fibrinolysis by slowing down the conversion of plasminogen to plasmin which may prevent bleeding. Although this medication is used extensively for other purposes, it has not been studied before to prevent post-polypectomy bleeding.

This pilot study will examine factors involved in the feasibility of conducting a large-scale randomized controlled trial (RCT). This pilot study will include 25 consecutive patients who are treated with tranexamic acid after endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCP's) to prevent PPDB.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Colorectal cancer is the second most common cancer in Canada. Colonoscopy and removal of precancerous polyps (polypectomy) reduces the incidence and mortality associated with colorectal cancer. However, polypectomy is associated with adverse events. Post-polypectomy bleeding has a significant impact on the life of the patient as it can require hospitalization, transfusions, repeat colonoscopy and rarely death. It is also a substantial cost to the health care system. Post-polypectomy delayed bleeding (PPDB) can occur up to a month following the procedure but is typically seen within the first week. Risk factors include the size of the polyp, antithrombotic or anticoagulation use, age, major comorbidities and proximal colon polyps. The incidence of bleeding after removal of large polyps is estimated to be around 2.6%-9.7%. There currently is no standard of care to prevent bleeding after polypectomy. Tranexamic acid reduces fibrinolysis by slowing down the conversion of plasminogen to plasmin which may prevent bleeding.

This pilot study will examine factors involved in the feasibility of conducting a large-scale RCT. This pilot study will include 25 consecutive patients who are treated with tranexamic acid after endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCP's) to prevent PPDB.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Tranexamic Acid

Intra-procedural tranexamic acid (TXA) - 1 gram, IV

Post-procedural tranexamic acid (TXA) - 1 gram, oral, three times per day for 5 days

Group Type EXPERIMENTAL

Tranexamic Acid Injection [Cyklokapron]

Intervention Type DRUG

Intra-procedurally, participants will receive 1 gram of intravenous tranexamic acid immediately following the polypectomy. Participants will also take oral tranexamic acid tablets (three times per day) at home for the five days following the procedure.
