Study summary

The purpose of the study is to evaluate whether the addition of Diamel, a nutritional supplement, to hypocaloric diet and exercise could improve the histological results (steatosis, necro-inflammatory activity and fibrosis), insulin resistance, aminotransferase levels and anthropometric measures in comparison with a placebo-controlled group with hypocaloric diet and exercise during 52 weeks of treatment in patients with nonalcoholic steatohepatitis.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Histological diagnosis of steatohepatitis (minimal histological criteria for steatohepatitis include steatosis involving at least 5% of hepatocytes, lobular inflammation, and/or fibrosis)
  • Age between 18 and 70 years
  • Ability to provide
  • Absence of significant alcohol ingestion (weekly ethanol consumption of less than 40 g)

Exclusion criteria

Exclusion Criteria:

  • Presence of other form of liver diseases (viral or hepatitis, drug-induced liver disease, metabolic and hereditary liver disease and α-1 antitrypsin deficiency)
  • Pregnancy or lactation
  • Decompensated cirrhosis
  • Presence of secondary cause of NAFL such as medications that induce steatosis (, estrogens, methotrexate, amiodarone, tamoxifen and calcium channel blockers) and gastrointestinal bypass surgery
  • Pharmacological treatment with some potential benefit on NAFL including ursodeoxycholic acid, vitamin E, betaine, pioglitazone, rosiglitazone, metformin, pentoxifylline or gemfibrozil
  • Fasting glucose levels greater than 250 mg per deciliter (13.3 mmolm per liter)
  • to liver
  • Refusal to participate in the study
  • Concomitant disease with reduced
  • Severe psychiatric conditions
  • Drug dependence
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 26, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
