About this study

Official title: Clinical Trial of Limonene on Regulating Metabolism-related Fatty Liver Disease (MAFLD) and Analysis of TCM Constitution

The prevention and treatment of metabolic-related fatty liver disease (MAFLD) involves many fields in preventive medicine and clinical medicine. So far, western medicine has not yet completed the elucidation of the mechanism of this type of disease, and there is a lack of effective therapeutic drugs.The purpose of this study was to evaluate the effectiveness and safety of limonene capsules (marketed product in China) in the treatment of metabolic-related fatty liver disease and related lipid-lowering mechanisms.

Read the detailed description

In April 2020, in the famous journal "Journal of Hepatology" in the field of liver disease, an internationally renowned liver disease expert group jointly proposed to replace non-alcoholic fatty liver disease (NAFLD) with metabolic associated fatty liver disease (MAFLD) . The concept of non-alcoholic fatty liver disease (NAFLD) was first proposed by Ludwig in 1980. It specifically refers to the excessive deposition of liver fat without excessive drinking. It is a type of liver that is closely related to insulin resistance and genetic susceptibility. Non-alcoholic fatty liver disease (NAFLD) is China country's largest chronic liver disease and the primary cause of abnormal liver enzymes in health examinations. It can lead to liver disability and death. It is also closely related to a variety of metabolic diseases and the high incidence of colorectal tumors. Western medicine has not yet fully elucidated its mechanism, and no drugs have been officially approved for the clinical treatment of NAFLD.

The new MAFLD nomenclature highlights the central role of metabolic factors in causing liver fat deposition in this type of liver disease. Traditional Chinese medicine believes that the abnormal accumulation of fat in the liver of such fatty liver patients is a pathological product of the microscopic loss of water and valley essence. It belongs to phlegm stasis, which blocks the liver collaterals. It coincides with the core of the metabolic etiology of recent liver disease experts.

Limonene is widely found in the essential oils of traditional Chinese medicine tangerine peel, green peel and other plants. Its taste is sour, sweet and pungent.It is returned to the liver and gallbladder meridian. It has an aromatic odor effect.

A large number of animal and cell experiments in the early stage have shown that limonene can inhibit the differentiation of adipocytes (pre-adipocytes) and promote the apoptosis of mature adipocytes, which is related to the inhibition of fatty acid synthesis. Toxicity load experiments show that limonene has very low toxicity. The accumulation of lipids in the liver of mice has a regulatory effect with significantly reducing the content of liver cholesterol and triglycerides, and also has a certain effect on lipid metabolism disorders, hyperglycemia and other metabolic syndromes. It can alleviate the effects of high-fat diet and N- Efficacy of nitro-L-arginine methyl ester-induced resistance to non-alcoholic fatty liver in rats. The main indication of limonene capsules (marketed product in China) is liver and gallbladder diseases. Traditional Chinese medicine believes that liver and gallbladder are related to each other. This comprehensively shows that limonene capsules are promising to be developed as a pure Chinese medicine product for the safe and effective treatment of MAFLD.

However, there has been no clinical evaluation of the clinical efficacy of limonene in the treatment of metabolic-related fatty liver disease. As a typical aromatic Chinese medicine, the mechanism of limonene in the treatment of fatty liver urgently needs to be revealed by modern medicine and molecular biology techniques.

This study intends to use a randomized, double-blind, placebo-controlled method to evaluate the effect of limonene on improving the degree of fat infiltration in patients with metabolic-related fatty liver disease (MAFLD), and to evaluate its body mass index BMI, waist circumference, waist-to-hip ratio, subcutaneous fat thickness, fat percentage, changes in metabolic components, safety,etc. The study also intends to use metabonomics, genomics, and molecular biology techniques to study the clinical relationship between metabolites and physiological and pathological changes in patients with liver fat infiltration, and to detect changes in key proteins and lipid components after drug intervention, which is to reveal mechanism on treatment of metabolic-related fatty liver disease by limonene. It is aimed to study the difference in the efficacy of limonene for people with different constitutions of traditional Chinese medicine (TCM) combined with the analysis of the constitution of TCM, and to clarify the modern scientific attributes of TCM therapy. Finally the study will develop a safe and efficient drug treatment technology to control liver fat infiltration , and to promote the development of clinical disciplines in the treatment of metabolic-related fatty liver disease.

What participants receive

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

  • Limonene capsuleDrug

    Also called DAN LENING capsule

    All the recruiters will be given treatment under the guidance of basic diet. Basic dietary guidelines include high-quality protein and fresh green leafy vegetables. It need to controlled sugar, various sweets and high-calorie foods, frying and other foods with high oil content and foods with high cholesterol content. Limonene capsules group and placebo group were used for treatment. The random number is generated by the central randomization system. All the recruiters were divided into placebo control group and limonene capsule administration group. The numbers will be assigned according to random numbers. In this study, qualified subjects were randomly assigned to the treatment group and the placebo control group at a ratio of 1:1. The drug was administered for 12 weeks, 3 times a day, 5 capsules each time.

The record says: finished, as of the sponsor's last update on 2 Nov 2021. 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 China. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 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?

Difference of controlled attenuation parameter (CAP) in liver fat (time frame: at baseline and twelve weeks after administration). The study lists 2 primary outcomes in all. 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 NCT04853082, which also lists 1 linked publication.

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 2 Nov 2021.
