E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Intrahepatic cholestasis of pregnancy (ICP), or obstetric cholestasis (OC) is a liver condition of pregnancy. Pregnant women diagnosed with ICP are more at risk of suffering from in utero fetal death, stillbirth, perinatal death (under 7 days), preterm delivery (less than 37 weeks' gestation) and neonatal unit admission. The principal research question asks: does treatment with ursodeoxycholic acid (UDCA) in ICP women, increase the chance of having a healthy baby, by reducing the problems listed above? |
|
E.2.2 | Secondary objectives of the trial |
The secondary research objectives of the study are to investigate the effect of UDCA treated ICP on other short term outcomes for both the mother and baby; and to assess the impact of UDCA treated ICP on health resource use: in terms of the total number of nights for mother and neonate, including intensive care and mode of delivery. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
ICP (pruritus with a raised serum bile acid above the upper limit of normal for the local laboratory)
20+0 to 40+6 weeks' gestation on day of randomisation (see note below on gestational age)
No known lethal fetal anomaly
Singleton or twin pregnancy
Aged 18 years or over
Able to give written informed consent
Determination of gestational age: for all calculations relating to gestational age (eligibility for enrolment, gestational age at delivery), gestational age will be calculated based on the following hierarchical model, as set out in the NICE guidelines for antenatal care:
From crown-rump length measurement on early ultrasound scan between 10+0 weeks and 13+6 weeks
From head circumference on ultrasound scan if crown–rump length is above 84 mm |
|
E.4 | Principal exclusion criteria |
Decision has already made for delivery within the next 48 hours
Allergy to any component of the UDCA or placebo tablets
Triplet or higher-order multiple pregnancy |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary short term perinatal outcome is a composite of perinatal death (as defined by in utero fetal death from 20+0 and 23+6 weeks’ gestation or stillbirth before delivery > 24+0 weeks’ gestation or neonatal death up to 7 days but
not death due to congenital anomaly) or preterm delivery (less than 37 weeks’ gestation) or NNU admissions (from infant delivery until hospital discharge to home). Each infant will only be counted once within this composite. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The time points of evaluation of this outcome measure are:
For deaths: between randomisation and 7 days post infant delivery
For preterm delivery: between randomisation and upto 37 weeks gestation
For infant neonatal unit admission: between randomisation and infant discharge (from hospital to home) |
|
E.5.2 | Secondary end point(s) |
The secondary short term maternal outcomes are:
• Peak maternal serum concentration (between randomisation and delivery) of following biochemical indices of
disease:
o Bile acids
o Alanine transaminase
o Bilirubin (total)
o Gamma glutamyl transferase
• Worst episode of itch over past 24 hours (mm on visual analogue scale) between randomisation and delivery
(assessed at clinic visits)
• Maximum dose of trial medication required
• Need for additional therapy
• Gestational diabetes mellitus
• Gestational Hypertension/Preeclampsia
• Assessment of myometrial contractions by CTG approximately one week (314
days) post randomisation
• Mode of onset of labour
• Mode of delivery classified as spontaneous vaginal, instrumental vaginal or caesarean
• Reason for induction or prelabour
caesarean section
• Estimated blood loss after delivery
The secondary short term perinatal outcomes are:
• In utero fetal death 20+0 to 23+6 weeks’ gestation
• Stillbirth (death before delivery > 24+0 weeks’ gestation)
• Preterm delivery (less than 37 weeks’ gestation)
• Neonatal death up to 7 days (excluding death due to congenital anomaly)
• Neonatal death up to 28 days (excluding death due to congenital anomaly)
• NNU admissions until infant hospital discharge to home
• Number of nights in each category of care (intensive, high dependency, special, transitional and normal)
• Total number of nights in hospital
• Birth weight (g)
• Customised/population birth weight centile (GROW)
• Gestational age at delivery
• Presence of meconium
• APGAR score at 5 minutes
• Umbilical arterial and venous pH (and base excess) at birth
• Need for supplementary oxygen prior to discharge
• Number of days when supplemental oxygen is required
• Need for ventilation support (CPAP/high flow/endotracheal ventilation)
• Pneumothorax (confirmed on chest Xray)
• Need for phototherapy
• Abnormal cerebral ultrasound scan
• Confirmed sepsis (positive blood or cerebrospinal fluid cultures)
• Necrotising Enterocolitis (Bell’s stage 2 and 3)
• Seizures (confirmed by EEG or requiring anticonvulsant therapy)
• Encephalopathy grade (worst at any time: mild, moderate, severe)
• Hypoglycaemia (blood glucose <2.6 mmol/l on two or more occasions)
• Other indications and main diagnoses resulting in neonatal unit admission
• Exclusively receiving breast milk at discharge from the neonatal unit.

E.5.2.1 | Timepoint(s) of evaluation of this end point |
