About this study

Official title: A Randomized Controlled Study on the Effects of Roux-en-Y Gastric Bypass Versus Sleeve Gastrectomy or Intensive Lifestyle Modifications on Non Alcoholic Steato-Hepatitis

Bariatric-metabolic surgery is effective in treating the cluster of conditions forming the metabolic syndrome, strictly associated with NAFLD and NASH. Recently, we and other authors have shown also in the long term (up 5 years) with randomized-controlled trials (RCTs) that bariatric-metabolic surgery allows remission of type 2 diabetes and obesity reduction, which are the two major pathogenetic factors of NASH development, with maintenance of weight loss.

Few small and mainly retrospective studies have shown that bariatric surgery is effective in improving NASH histologic picture in obese subjects.

The aim of our proposal is to conduct a 3 arm single centre, superiority, RCT comparing Roux-en-Y Gastric Bypass (RYGB) with Sleeve Gastrectomy (SG) and with Intensive Lifestyle Modifications (ILM) for the treatment of Non-Alcoholic Steato-Hepatitis.

Read the detailed description

This is a Randomized Controlled multicentre Trial involving the Catholic University (Professor Geltrude Mingrone as PI and Professor Marco Raffaelli as co-PI)

The research question in PICOT format (P) - Population: Adults 25 to 70 years of age and BMI ≥ 30 and ≤55 kg/m2 with histological diagnosis of NASH.

(I) - Intervention: Roux-en-Y Gastric Bypass or Sleeve Gastrectomy, both plus lifestyle counseling.

(C) - Comparison: Intensive Lifestyle Modifications. (O) - Outcome: the histological resolution of NASH without worsening of fibrosis at 1 year after the interventions.

(T) - Time: One year after the intervention started.

1.3.3.2 Research Goals

  • The primary aim of our study is to assess the effects of bariatric-metabolic surgery or ILM on NASH at 1 year after the interventions.
  • Secondary aims are to assess the safety of bariatric surgery and the improvement of at least 1 stage of liver fibrosis without worsening of NASH, insulin sensitivity , T2DM, and lipoprotein profile changes.

The liver biopsy will be performed at baseline and at 1 year follow-up. Another liver biopsy will be performed at 3 and 5 years follow-up.

What participants receive

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

  • RYGBProcedure or surgery

    Roux-\&-Y Gastric Bypass (RYGB) involves the use of a surgical stapler to create a small and vertically oriented gastric pouch with a volume of 30 ml. The upper pouch is completely divided by the gastric remnant and is anastomosed to the jejunum, 75 cm distally to the Treitz's ligament , through a narrow gastrojejunal anastomosis in a Roux-en-Y fashion. Bowel continuity is restored by an entero-entero anastomosis, between the excluded biliary limb and the alimentary limb, performed at 100 cm from the gastrojejunostomy. Lifestyle modification counselling is provided to each patient.

  • SGProcedure or surgery

    The SG is created using a linear stapler with two sequential 4.8/60-mm green load firings for the antrum, followed by two or three sequential 3.5/60-mm blue loads for the remaining gastric corpus and fundus. The stapler is applied alongside a 48-Fr calibrating bougie. The resection line is performed avoiding the ''critical area'' by resecting the fundus 1.5 cm from the angle of His. Staple lines are buttressed with bovine pericardial strips. The resected stomach is grasped at the antral tip by a laparoscopic grasper and retrieved through one of the trocar sites. A methylene blue dye test by a nasogastric tube is routinely performed at the end of the procedure. The residual gastric remnant capacity is 60-80 ml. Drains are not routinely placed, and the nasogastric tube is removed at the end of the procedure. Upper gastrointestinal contrast (Gastrografin) study is performed on the first postoperative day. Lifestyle modification counselling is provided to each patient.

  • Intensive Lifestyle ModificationOther

    Resting calorie requirements will be calculated via the Harris Benedict equation (24) and an activity factor, and subjects will be instructed not to change their activity level other than that suggested by physicians during the study. The diet will contain 1/3 kcal less than the calculated energy expenditure and 30% fat of which 10% saturated, 55% lower glycemic index carbohydrates and 15% proteins.

    The participants will be encouraged to gradually increase their walking to achieve 10,000 steps per day. A moderate intensity physical activity program of 1 hour of aerobic exercise 2-3 hours per week will be recommended to all subjects. Their physical activity will be assessed by IPAQ-SF.

What is being measured

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

  1. histological resolution of NASH without worsening of fibrosis at 1 year after the interventions

    Histological diagnosis of NASH is established according to widely accepted criteria, using the NAFLD activity score (NAS) algorithm proposed by the NASH Clinical Research Network (CRN). These criteria include presence of steatosis in >5% of hepatocytes, hepatocellular ballooning and lobular inflammatory infiltrates. The presence and stages of fibrosis will be also assessed using the NASH-CRN system: stage 0 =no fibrosis; stage 1 =centrilobular pericellular fibrosis; stage 2 =centrilobular and periportal fibrosis; stage 3 =bridging fibrosis; and stage 4 =cirrhosis.

    Measured: 1 year

Secondary outcomes (7)
  1. Adverse health events including the need for re-operation

    adverse events include early operation complications

    Measured: 1 year

  2. Improvement of at least 1 point of histological liver fibrosis without worsening of NASH

    liver fibrosis will be examined in liver biopsies

    Measured: 1 year

  3. Changes in glycemic control (only in diabetic patients)

    diabetes remission or improvement of glycemic control (glycated hemoglobin HbA1c)

    Measured: 1 year

  4. Changes in insulin sensitivity

    HOMA IR or oral glucose minimal model

    Measured: 1 year

  5. Changes in food intake

    food intake diary

    Measured: 1 year

  6. Changes in physical activity

    Physical activity questionnaire

    Measured: 1 year

  7. Changes in body composition: Fat-Free Mass (FFM), Fat Mass (FM).

    FFM and FM will be assessed by DEXA

    Measured: 1 year

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 2 inclusion and 1 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 21 Feb 2023. 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 Italy. 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.

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?

histological resolution of NASH without worsening of fibrosis at 1 year after the interventions (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03524365, which also lists 3 linked publications.

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 21 Feb 2023.
