Trial summary

Chronic liver diseases are often characterized by portal hypertension, a major complication involving haemodynamic changes due to increased intrahepatic vascular resistance. It has become well established that nitric oxide (NO) plays a crucial role in the haemodynamic abnormalities that develop in chronic portal… Read more about this study

About this study

Official title: Preliminary Efficacy And Tolerability Of Oral NCX-1000 After Repeated Administrations In Patients With Portal Hypertension: A Double-Blind Dose Escalating Study

Chronic liver diseases are often characterized by portal hypertension, a major complication involving haemodynamic changes due to increased intrahepatic vascular resistance. It has become well established that nitric oxide (NO) plays a crucial role in the haemodynamic abnormalities that develop in chronic portal hypertension.

NCX-1000 is a NO-releasing derivative of ursodeoxycholic acid that would compensate for the defective liver NO production in cirrhosis.

This study intends to demonstrate the desired therapeutic activity (reduction in portal pressure) in a small number of target patients, to assess the safety and tolerability after repeated oral administrations of NCX-1000, and to get preliminary pharmacokinetic data in this population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Hepatic Venous Pressure Gradient (HVPG) will be evaluated at entry (Day 1) and after the Maximal Tolerated Dose (MTD) on Day 16, in fasting and post-prandial (after a standardized liquid breakfast) states.

    The portal pressure, as determined by HVPG, was obtained by subtracting the free hepatic venous pressure from the wedged hepatic venous pressure and rounded to the nearest 0.5 or integer value.The pressures were recorded 3 times for each evaluation and the HVPG value was the mean of the 3 Recordings

    Measured: Day1 and Day 16

Secondary outcomes (2)
  1. Safety parameters: systolic and diastolic blood pressures, heart rate, physical examination, laboratory tests and Adverse Events (AEs)

    Usual safety parameters. Blood pressures were assessed every 30 minutes for 4 hours after drug intake. Other parameters were assessed or reported at Study visits

    Measured: At various times

  2. Plasma levels of NCX-1000 and its main metabolites will be evaluated to get preliminary pharmacokinetic data.

    Usual pharmacokinetic (PK) evaluation

    Measured: 0, 1, 2, 3, and 4 hours after the first 3 doses anf after the last dose

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NCX-1000 in people with Portal Hypertension, run by Forest Laboratories at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 9 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Preliminary analysis of 11 patients did not demonstrate the efficacy required.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Hepatic Venous Pressure Gradient (HVPG) will be evaluated at entry (Day 1) and after the Maximal Tolerated Dose (MTD) on Day 16, in fasting and post-prandial (after a standardized liquid breakfast) states. (time frame: Day1 and Day 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Feb 2017.
