This study evaluates the use of tranexamic acid (TXA) in addition to standard therapy in children receiving chemotherapy or blood and/or marrow transplantation to decrease the risk of bleeding. Half of participants will receive tranexamic acid and half of participants will receive placebo.

The purpose of this study is to conduct a prospective, randomized, blinded, placebo controlled trial to evaluate the safety and feasibility of the addition of antifibrinolytic therapy with tranexamic acid to the standard care in patients who are thrombocytopenic due to primary bone marrow disorders or chemotherapy, immunotherapy and/or radiation therapy in order to prevent bleeding. The results of this study will change practice by providing evidence as to whether or not TXA is effective and safe treatment when used as an adjunct to platelet transfusion therapy in the thrombocytopenic patient.

This trial is designed as a prospective, randomized, controlled, blinded (patient, caregiver, physician, assessor) trial with two parallel groups and a primary endpoint of feasibility and safety. Randomization will be performed as block randomization with a 1:1 allocation within blocks of size four.

The investigational pharmacy will be notified when patients enroll on trial. When participants meet criteria for randomization, this will be completed by the Investigational Pharmacy. The pharmacy will prepare and distribute to floor nursing staff all doses of tranexamic acid (available in IV form as a colorless liquid) or placebo (as an equal volume of normal saline). Labels will not carry identifiers of which study arm the enrolled patient is on.

A Pediatric Trial Using Tranexamic Acid in Thrombocytopenia

Anonymized public data set will be available after publication of primary results

Adverse Events and Serious Adverse Events (SAE) will be collected on subjects throughout their participation in the study and up to 30 days following discontinuation of the study drug, regardless of attribution. Adverse events and serious adverse events will be tabulated by type and grade according to the NCI CTCAE v 4.03.

The hypothesis is that tranexamic acid can be safely added to standard care regimens in patients with hematologic malignancies or solid tumors during periods of severe thrombocytopenia. Analysis limited to a descriptive assessment of the safety of tranexamic acid in patients with hematologic malignancies or solid tumors by reported adverse events, serious adverse events and death.

Number of participants eligible for study enrollment and recruited.

The hypothesis is that tranexamic acid can be safely added to standard care regimens in patients with hematologic malignancies or solid tumors during periods of severe thrombocytopenia. A descriptive assessment of feasibility of recruitment by monitoring number of patients screened, number of patients eligible for enrollment and rate of recruitment (both start-up and ongoing) during study period to be completed by collecting data on the number of patients screened, the number of patients eligible for study inclusion, the number of eligible patients who consent to study inclusion and the number of consented patients activated to the study drug, organized in visual form by CONSORT diagram.

Proportion of patients with bleeding of WHO grade 2 or above, after activation of study drug. Bleeding graded on a scale ranging from 1 (minor bleeding) through 4 (bleeding that is fatal or life-threatening).

Number of platelet and red blood cell transfusions per patient during the first 30 days post prescription activation of study drug

Number of days alive and without WHO grade 2 bleeding or greater during the first 30 days post activation of study drug. Bleeding graded on a scale ranging from 1 (minor bleeding) through 4 (bleeding that is fatal or life-threatening).

Any venous or arterial thrombosis on standard diagnostic imaging post-randomization

Proportion of patients with bleeding of any grade as assessed by WHO bleeding score, after activation of study drug

Highest grade of bleeding (as measured on WHO bleeding scale) during study period in each enrolled patient. Bleeding graded on a scale ranging from 1 (minor bleeding) through 4 (bleeding that is fatal or life-threatening).

The pre-specified analysis described in the study protocol stated the following: "For secondary endpoints, events of WHO Grade 2 or higher bleeding will be compared through the use of odds ratio or T-test statistic of means. The mean number of platelet transfusions will be analyzed using a T-test statistic of means." This analysis was not completed as it would be scientifically inappropriate due to insufficient enrollment. Instead a descriptive analysis was completed.
