Prolonged Release Pirfenidone for Advanced Residual Liver Fibrosis (MINERVA).

Evaluation of Prolonged-release Pirfenidone in Patients With Viral C Hepatitis, With Sustained Viral Response and Advanced Residual Liver Fibrosis. Potential Role of Epigenetics to Understand Therapeutic Changes (MINERVA).

Prolonged-Release Pirfenidone (PR-PFD) is an anti-fibrogenic and anti-inflammatory molecule used for the treatment of idiopathic pulmonary fibrosis (approved by FDA) and liver fibrosis (approved in Mexico by COFEPRIS). PFD effects are mediated in part through inhibition of TGFβ, TNFα, IL-1 and IL-6, along with NFκB activation down-regulation causing reduced TNFα and IFNγ levels.

The aim of this protocol is to know if the epigenetic factors induced by PR-PFD have a regulatory role to understand the progression variants in liver fibrosis in a group of patients with viral hepatitis C, with a history of sustained viral response and advanced residual liver fibrosis. To assess the safety and efficacy of two daily doses of pirfenidone (KitosCell® LP), in patients with compensated liver cirrhosis.

Study Overview

• Status: Recruiting
• Conditions: Liver Cirrhosis; Hepatitis C, Chronic; Epigenetic Disorder
• Intervention / Treatment: Drug: Prolonged-Release Pirfenidone

Detailed Description

Design: Observational clinical study, in an open population, of 12 months duration. Sixty patients with chronic Viral C hepatitis, who have been treated with direct-acting antivirals, with a sustained viral response and who still have advanced fibrosis (F3-F4).

Aim: to know if the epigenetic factors induced by PR-PFD have a regulatory role to understand the progression variants in liver fibrosis in a group of patients with viral hepatitis C, with a history of sustained viral response and advanced residual liver fibrosis. To assess the safety and efficacy of two daily doses of pirfenidone (KitosCell® LP), in patients with compensated liver cirrhosis.

Dosage: 1200 mg / day of Pirfenidone (KitosCell® LP) Variables to Analyze: Reduction of fibrosis and evaluation of epigenetic changes in the expression of various genes: PPARγ, PPARδ, PPARα, TGFβ1, Col1A1 and PDGFα. Additionally, changes in the expression levels of miR-122, miR192, miR-200a / b, miR-34a, miR-16, miR-21 and miR-181b will be evaluated, as well as changes in the transcriptome in ccfRNA.

Ethical considerations: The study will be conducted in accordance with the Declaration of Helsinki and the E6 Good Clinical Practice Standards International Conference on Harmonization (ICH).

Statistical Data Analysis: Descriptive statistics will be used and according to analytical statistical requirements that include parametric or non-parametric tests. The value of p <0.05 will be considered as significant.

2. History of treatment with direct acting antivirals (AAD).
3. Demonstration of negative viral load at least 6 months after completing treatment with AAD, considered as sustained viral response (SVR).
4. Fibrotest and / or Liver Elastography test with advanced liver fibrosis scores (F3-F4).
5. Verification of advanced liver fibrosis in a liver biopsy.
6. Patients with Child Pugh functional class A or B and in stable clinical conditions (without active variceal hemorrhage, ascites or refractory encephalopathy) with consumption of drugs at stable doses in at least 30 days.

7. Laboratory tests that confirm her condition and functional class, with results that, in the opinion of the main researcher, do not put the patient at risk:

   • Complete blood count, with hemoglobin values ≥ 10 g / dL, leukocytes ≥ 3,000 mL, platelets ≥ 50,000 mL

7. Concomitant systemic infection including viral hepatitis B, HIV, as well as respiratory infections, urinary, digestive, cellulite, etc.
8. Serious concomitant conditions such as Heart Failure, Respiratory Failure and Chronic Kidney Failure.
9. Malignant neoplasms including hepatocellular carcinoma. Patients with basal cell carcinoma or those with malignancies with more than 5 years of inactivity may be considered for the study.
10. Decompensated diabetes mellitus (defined as that with fasting blood glucose values greater than 175 mg / dL and / or glycated hemoglobin greater than 8%).
