Brief Summary:
This is a pilot study aimed at comparing the effect of metformin versus ursodeoxycholic acid in women with intrahepatic cholestasis in pregnancy. The study will be conducted in three NHS hospital sites, over an 18 month period.

Condition or disease Intervention/treatment Phase
Intrahepatic Cholestases Pregnancy Complications Drug: Metformin Drug: Ursodeoxycholic Acid Phase 2 Phase 3

Detailed Description:

Intrahepatic cholestasis is a condition that affects pregnant women. It is characterised by itching, usually in the third trimester of pregnancy and is associated with an increase in the liver enzymes and bile salts. This can be associated with maternal and neonatal morbidity, and rarely perinatal mortality.

The investigators propose to assess and compare the effect of Metformin versus Ursodeoxycholic acid on lowering liver enzymes and bile salts, improving maternal morbidity and improving neonatal outcomes.

This study is a pilot study that will be conducted at 3 NHS hospital sites where patients will randomly assigned to receive either Metformin or Ursodeoxycholic acid. There will be 20 patient in each arm. Recruitment will commence in February 2017 and will run for an 18 month period.

Metformin Hydrochloride (HCl) Tablets, is an oral antihyperglycemic drug used in the management of type 2 diabetes
Other Name: Glucophage




Primary Outcome Measures :
  1. Normalisation of maternal serum concentration of bile salts and liver enzymes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]
    Normalisation of Bile acids and liver enzymes - both parameters are the cornerstone for a diagnosis of intrahepatic cholestasis. They have been separated into two outcomes due to to the different laboratory indices of measurement. Results will be aggregated together to report number of patients with abnormal results

  2. Normalisation of maternal serum concentration of liver enzymes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]
    Normalisation of liver enzymes Alanine transaminase Aspartate transaminase Bilirubin (total) Gamma glutamyl transferase Results will be aggregated together to report the number of patients with abnormal liver enzymes


Secondary Outcome Measures :
  1. Fetal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]
    Perinatal death

  2. Fetal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]

  4. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    Birth weight (g)

  5. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    Birth weight percentile

  6. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    Gestational age at delivery


Other Outcome Measures:
  1. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    Presence of meconium

  2. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    APGAR score at 5 minutes

  3. Fetal outcomes [ Time Frame: Immediately upon delivery date ]
    Umbilical arterial pH at birth

  4. Maternal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]

  6. Maternal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 20 weeks ]
    Gestational diabetes

  7. Maternal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]
    Postpartum haemorrhage

  8. Maternal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 20 weeks ]
    Mode of delivery

  9. Maternal outcomes [ Time Frame: From date of randomisation to date of delivery assessed up to 26 weeks ]
