Study of the Efficacy and Safety of Nicotinamide in Patients With Liver Fibrosis (NICOFIB)

Официальное название

Randomized, Double-blind, Placebo-controlled Study of the Efficacy and Safety of Nicotinamide in Patients With and Liver Fibrosis (NICOFIB)

Обзор

The objective of this clinical trial, a pilot study, is to assess the impact of nicotinamide (NAM) on individuals with hepatic fibrosis. The main question it aims to answer is: \- To determine if the treatment with NAM is able to arrest, or even reduce, the hepatic fibrosis. In addition, we also want to study the effect of NAM on: * General parameters (weight, HOMA-IR, etc). * Adiposity distribution (liver and body). * Systemic inflammation. * Thermogenic capacity of adipose tissue. * Microbiota composition. Researchers will compare NAM to a placebo, to see if NAM can arrest or revert hepatic fibrosis and its associated effects. Participants will take either NAM or placebo. The dosage will be 1.2g/m2 NAM per day, for one year.

Подробное описание

Patients with a Fibroscan \> 8 kPa will be offered to participate in this study. Participants will receive either placebo or a NAM dose adjusted to body weight. The duration of the treatment is 12 months.

Participants will be subjected to a total of 5 follow-up and/or control visits:

Visit 1

* Physical examination(weight, height, BMI, waist circumference, neck circumference, blood pressure, and heart rate). * Assessment of muscle status and risk of sarcopenia: grip strength, chair test. * Basal electrocardiogram. * Blood analysis. * Bioelectrical impedance analysis. * Nuclear magnetic resonance. * Thermographic image. * Food questionnaire (PREDIMED). * International Physical Activity Questionnaire (IPAQ). * Collection of blood, urine, and feces samples for storage in the biobank.

Visit 2. Control visit (time month 1)

* Monitoring of adverse events (AE) and adverse reactions (AR). * Electrocardiogram. * Control blood analysis: sodium, potassium, liver biochemistry (AST, ALT, bilirubin, GGT, FA), renal function (urea, creatinine, estimated glomerular filtration), and coagulation tests. * Physical examination and measurement of vital signs.

Visit 3. Follow-up visit (time month 3)

* Monitoring of AE and AR. * Drug adherence questionnaire. * Electrocardiogram. * Blood analysis. * Physical examination (weight, BMI, waist circumference, neck circumference, blood pressure, and heart rate). * Collection of blood, urine, and feces samples for biobank. * Collection of concomitant medication. * Adherence to study treatment and dietary recommendations.

Visit 4. Follow-up visit (time month 6)

* Monitoring of AE and AR. * Drug adherence questionnaire. * Electrocardiogram. * Blood analysis. * Physical examination (weight, BMI, waist circumference, neck circumference, blood pressure, and heart rate). * Collection of blood, urine, and feces samples for biobank. * Collection of concomitant medication. * Adherence to study treatment and dietary recommendations.

Visit 5. Control visit (time month 9).

* Monitoring of AE and AR. * Drug adherence questionnaire. * Electrocardiogram. * Control blood analysis. * Physical examination. * Collection of concomitant medication.

Visit 6. Final exploration (time month 12)

* Monitoring of AE and AR. * Drug adherence questionnaire. * Food questionnaire (PREDIMED). * Physical Activity Questionnaire (IPAQ). * Physical examination and measurement of vital signs (weight, BMI, waist circumference, neck circumference, blood pressure, and heart rate). * Assessment of muscle status and risk of sarcopenia: FPM, chair test. * Electrocardiogram. * Blood analysis. * Measurement of NAM and derived metabolites in serum and urine. * Nuclear magnetic resonance. * Bioimpedance. * Thermographic image. * Fibroscan® with CAP. * Collection of blood, urine, and feces samples for biobank

The safety of the participants will be assessed using a record of the AEs and ARs that could arise and their annotation in the EDC, as well as a regular evaluation of liver, kidney, and heart function at baseline, 1, 3, 6, 9 and 12 months
