Study information

Scientific title

A pilot study to evaluate the safety, tolerability and efficacy of obeticholic acid (INT-747) for the treatment of portal hypertension

Acronym

PESTO

Study hypothesis

1. Obeticholic acid (OCA) is safe and tolerated in patients with cirrhosis and portal hypertension
2. Obeticholic acid (OCA) will reduce the Hepatic Venous Pressure Gradient (HVPG) in patients with portal hypertension

Ethics approval

National Research Ethics Service (NRES) North London REC 3 Committee approval granted on:
10 Dec 2010 (Final Protocol)
01 Mar 2011 (Amendment 1)
05 April 2011 (Amendment 2)
02 December 2011 (Amendment 3)

Condition

Portal hypertension in patients with alcoholic cirrhosis of the liver

Intervention

1. Physical Examination
2. Vital signs
3. 12 Lead electrocardiogram (ECG)
4. Blood sampling and analysis – peripheral and hepatic blood samples
5. Urine collection and analysis
6. Hepatic vein catheterisation to measure HVPG and other hepatic haemodynamic measures (efficacy cohort only)

Intervention type

Drug

Phase

Not Applicable

Drug names

Obeticholic acid (OCA)

Primary outcome measures

1. Safety and tolerability as measured and assessed throughout the study by monitoring adverse experiences, clinical laboratory values in blood and measures of blood pressure and heart rate, all at baseline, Day 4, Day 7 and at follow up after 2-4 weeks and ECG at baseline and Day 7
2. Portal hypertension measured at baseline and Day 7 by HPVG. Outcome measure of a reduction of ≥15% at Day 7 compared to baseline or a reduction to <12 mmHg

Secondary outcome measures

1. Hepatic haemodynamics including hepatic blood flow (measured from the concentration of indocynanine green in the hepatic venous blood vs peripheral venous blood using the Fick Principle) and intrahepatic resistance (fluoroscopic examination after catheterisation of the right hepatic vein following injection of contrast medium)
2. Liver function: measured by gamma glutamyl transpeptidase (GGT), alanine transaminase (ALT), alkaline phosphatase (ALP), albumin, prothrombin time and bilirubin (total and unconjugated)
3. Pharmacokinetics: measured by plasma drug and metabolite concentrations
4. Inflammation: measured by C-reactive protein

Eligibility

Participant inclusion criteria

1. Male or female age 18-70 years
2. History of alcoholic cirrhosis with clinical or radiological and biochemical evidence of cirrhosis
3. Evidence of early decompensated cirrhosis (Child-Pugh score ≥7 to ≤12)
4. Patients recruited into the cohort evaluation of efficacy must have significant portal hypertension defined as an HVPG ≥ 12 mmHg
5. Patients with large or grade 3 oesophageal varices as identified by endoscopy within 6 months of screening should be in an endoscopic band ligation program at the time of study entry
6. Female patients must be postmenopausal, surgically sterile, or if premenopausal, must be prepared to use at least one effective (≤1% failure rate) method of contraception during the course of the study and for 14 days after the end of dosing. Male patients with female partners of child bearing potential must be prepared to use at least one effective method of contraception with all sexual partners unless they have had a prior vasectomy. Effective methods of contraception are considered to be:
6.1. Condom (male or female)
6.2. Diaphragm, with spermicide
6.3. Hormonal (e.g. contraceptive pill, patch, intramuscular implant or injection)
6.4. Intrauterine device (IUD)
6.5. Vasectomy (partner)
7. Must be willing and able to give written informed consent and agree to comply with the study protocol
