Health condition
Health condition(s) or problem(s) studied:
Bioequivalence study conducted in healthy volunteers comparing two formulations of tranexamic acid with no health condition or problem studied.

Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, tranexamic acid is a haemostatic agent used to prevent excessive bleeding in patients with hereditary angioedema. It is also indicated for the short-term treatment of traumatic hyphaema, patients with coagulopathies undergoing minor surgery and menorrhagia. Administration by IV is used for reduction of peri/ postoperative blood loss, need for blood transfusion in cardiac surgery (adults, paediatric), total knee and hip arthroplasty (adults). 296145 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover over study design whereby each participant receives the test formulation of tranexamic acic (1 x 500 mg) on one occasion and the innovator formulation of tranexamic acic (1 x 500 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of tranexamic acid.

Each dose (1 x 500 mg) will be taken orally with 240 ml of water at ambient temperature. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).
Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance can be monitored and for 13 hours after dosing.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing.

Screening laboratory tests (including HIV, Hepatitis and drugs of abuse testing), and post study laboratory tests will be completed to assess the health of participants.

Comparator / control treatment
Single dose, crossover over study design whereby each participant receives the test formulation of tranexamic acid (1 x 500 mg) on one occasion and the innovator formulation of tranexamic acid (1 x 500 mg) on one occasion with each dose seperated by a one week washout period. The comparator/control for this trial is the innovator formulation of tranexamic acid.

Outcomes
Primary outcome [1] 296050 0
To compare the bioavailability of tranexamic acid (as summarised by Cmax and AUC) for the two formulations. All plasma samples will be assayed for tranexamic acid using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs. Randomisation will be performed using a randomisation table created by computer software (i.e. computerised sequence generator).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be identified by a 3 digit screening number and a 2 digit subject number. the screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number (randomisation number) after acceptance into the study
Masking / blinding
