| E.1.2 | Version | 20.0 |
| E.1.2 | Level | PT |
| E.1.2 | Classification code | 10053476 |
| E.1.2 | Term | Traumatic haemorrhage |

| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| In an emergency situation, tranexamic acid is commonly administered intravenously, but this route might not always be feasible. If tranexamic acid injected intramuscularly is absorbed quickly, this route of administration of tranexamic acid might be an alternative to the intravenous route. We will determine how fast tranexamic acid is absorbed after intramuscular administration in bleeding trauma patients. |
|
| E.2.2 | Secondary objectives of the trial |
| The secondary objectives will be to assess the safety of the intramuscular injection of tranexamic acid. The sites on the patients’ bodies where the intramuscular injections where given will be observed once a day for 7 days to check for possible reactions (i.e. redness of the skin, nodules under the skin, bruising). |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
- Adult (appear to be at least 16 years old) trauma patients - Received 1 gram of intravenous tranexamic acid for the management of haemorrhage - A second dose of tranexamic acid is clinically indicated |
|
| E.4 | Principal exclusion criteria |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| Serum concentrations of tranexamic acid over time. |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
Eligible patients would have received 1 gram of tranexamic acid (TXA) as an IV injection. Timepoints of blood sample collection will be: T-3 = TXA IV injection T-2 = T-3 + 10 (± 5 min) if the clinical situation allows* T-1 = immediately before IM injection T0 = TXA IM injection (minimum 1h 30 min after IV injection) T1 = T0 + 15 min (± 10 min) T2 = T0 + 45 min (± 15 min) T3 = T0 + 1h 30 min (± 15 min) T4 = T0 + 3h (± 1h) T5 = T0 + 6h (± 1h) T6 = T0 + 10h (±1h) |
|
| E.5.2 | Secondary end point(s) |
Local reactions at injection site Adverse events
|
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
| The timepoints will be the same as T1 to T6 mentioned in Q23-1 plus once a day from day 2 to day 7. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
| The end of trial will be day 7 of the last participant enrolled. We need to follow patients up to day 7 because reactions at sites of injections and adverse events are endpoints of the study. |
