TRIAL DESCRIPTION
Public title World Maternal Antifibrinolytic Trial-2
Official scientific title Tranexamic acid for the prevention of postpartum bleeding in women with anaemia: an international, randomised, double-blind, placebo controlled trial
Brief summary describing the background and objectives of the trial BACKGROUND: Postpartum haemorrhage (PPH) is responsible for about 100,000 maternal deaths every year, most of which occur in low and middle income countries. Tranexamic acid (TXA) reduces bleeding by inhibiting the enzymatic breakdown of fibrin blood clots. TXA decreases blood loss in surgery and reduces death due to bleeding after trauma. When given within three hours of birth, TXA reduces deaths due to bleeding in women with PPH. However, for many women, treatment of PPH is too late to prevent death. Over one-third of pregnant women in the world are anaemic and many are severely anaemic. These women have an increased risk of PPH and suffer more severe outcomes if PPH occurs. There is an urgent need to identify a safe and effective way to reduce postpartum bleeding in anaemic women. AIM: To determine the effect of TXA on postpartum bleeding in women with moderate or severe anaemia. PRIMARY OUTCOME: Proportion of women with a clinical diagnosis of primary PPH. The cause of PPH will be described. SECONDARY OUTCOMES: Maternal health and wellbeing (fatigue, headache, dizziness, palpitations, breathlessness, exercise tolerance, ability to care for her baby, health related quality of life, breastfeeding). Maternal blood loss and its consequences (estimated blood loss, haemoglobin, haemodynamic instability, blood transfusion, signs of shock, use of interventions to control bleeding). Other health outcomes (death by cause, vascular occlusive events, organ dysfunction, sepsis, side effects, time spent in higher level facility, length of hospital stay, and status of baby/ies). We will also conduct a pre-planned cohort analysis of data from the WOMAN-2 trial to assess the effect of pain control and episiotomy on the risk of post-partum haemorrhage. We hypothesize that painful procedures such as episiotomy will significantly increase the risk of postpartum haemorrhage and that pain control will reduce the risk of PPH.

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group Tranexamic Acid Total dose 1 gram (10mL) 1 gram (10mL) will be administered as a slow intravenous injection at rate of about 1 mL/minute using standard local intravenous administration procedure. A single dose of 1 gram of TXA by intravenous injection will be given immediately after the umbilical cord is cut or clamped, and no more than 15 minutes later. Ampoules and packaging for both Tranexamic acid and Placebo will be identical in appearance. 5000
Control Group Sodium Chloride 0.9 percent Total dose 1 gram (10mL) 1 gram (10mL) will be administered as a slow intravenous injection at rate of about 1 mL/minute using standard local intravenous administration procedure. A single dose of 1 gram of Sodium Chloride 0.9 percent by intravenous injection will be given immediately after the umbilical cord is cut or clamped, and no more than 15 minutes later. Ampoules and packaging for both Tranexamic acid and Placebo will be identical in appearance. 5000 Placebo

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome Postpartum Haemorrhage (cause will be described) - Clinical assessment: This may be an estimated blood loss of more than 500 mL or any blood loss sufficient to compromise haemodynamic stability within 24 hours of delivery. Haemodynamic instability is based on clinical judgement and assessed using clinical signs (low systolic blood pressure, tachycardia, reduced urine output). 24 hours after administration of the trial medication or at discharge from hospital, whichever is earlier
Secondary Outcome Postpartum blood loss - Clinical assessment 24 hours after administration of the trial medication or at discharge from hospital, whichever is earlier
