About this study

Official title: A Randomized Phase II Study of the Effect of a Low Calorie Diet on Patients Undergoing Liver Resection

The purpose of this study is to measure the effect of a short-term low calorie diet on patients with a Body Mass Index (BMI) over 25 who are undergoing liver surgery.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Optifast 800Dietary supplement

    Five units of Optifast 800 plus an unlimited volume of calorie-free fluids per day for one week prior to hepatic resection.

What is being measured

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

  1. The effect of a low calorie diet on intra-operative blood loss, technical ease of hepatic transection, complication rates (including infectious complications), length of stay and mortality in patients undergoing liver surgery.

    Intra-operative blood loss will be strictly quantified. Units of autologous or donor blood transfused will be recorded. The surgeon will assess the ease of liver mobilization and parenchymal transection using a 1-5 scale where 1 is easy and 5 is hard. Post-operative complications, length of stay and mortality will be recorded.

    Measured: 30 days post-operatively

Secondary outcomes (2)
  1. The effect of a low calorie diet on steatosis and steatohepatitis.

    Using tissue from hepatic parenchyma adjacent to resected neoplasms steatosis and steatohepatitis will be evaluated by a pathologist blinded to dietary intervention. Steatosis will be defined as mild, moderate or severe if 5-33%, 34-66%, or >66% of hepatocytes contain fat inclusions. Steatohepatitis will be defined using NAFLD (Non-Alcoholic Fatty Liver Disease) Activity Score (NAS) as an NAS 4 or greater, with <4 defined as no steatohepatitis.

    Measured: 30 days post-operatively

  2. The mechanism of decreased steatosis in patients undergoing a low-calorie pre-op diet by measuring levels of expression of molecules involved in the de novo synthesis, hepatic uptake and degradation of lipids.

    Levels of expression of molecules involved in the de novo synthesis, hepatic uptake and degradation of lipids will be measured to evaluate the mechanism of decreased steatosis.

    Measured: 30 days post-operatively

Questions about this trial

What is this clinical trial studying?

A study testing Optifast 800 in people with Nonalcoholic Fatty Liver Disease and Hepatic Steatosis, run by Dartmouth-Hitchcock Medical Center at 3 sites in United States.

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 4 inclusion and 3 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: finished, as of the sponsor's last update on 8 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 3 sites in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 effect of a low calorie diet on intra-operative blood loss, technical ease of hepatic transection, complication rates (including infectious complications), length of stay and mortality in patients undergoing liver surgery. (time frame: 30 days post-operatively). 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 8 Feb 2017.
