Study record managers: refer to the Data Element Definitions if submitting registration or results information. Although liver biopsy is the current standard for histological characterization of the liver parenchyma, this invasive procedure has a significant risk of - potentially lethal -bleeding. Moreover, as liver disease may focally or heterogeneously affect the liver, histological findings may be false negative or not be representative. Non-invasive imaging modalities e. Moreover, in recent years new developments have opened the door towards a better, more comprehensive appreciation of the status of the liver. One of these is elastography assessing the mechanical, viscoelastic properties of the liver, thus providing valuable information with regard to the liver stiffness or elasticity , and be used for accurate staging of liver fibrosis 1,2. Another approach is tissue characterization using the relaxation behaviour of liver tissue in a high-field magnetic environment 'relaxometry'. As relaxation times are tissue specific, focal or diffuse pathology may alter i. Indications For Liver Biopsy And Histological Assessment

Nasdaq:ICPT Intercepta biopharmaceutical company focused on the development and commercialization of novel Histopogical to treat progressive non-viral liver diseases, today announced clinical data from a liver Indications For Liver Biopsy And Histological Assessment substudy from the POISE Phase 3 trial suggesting that long-term OCA treatment in patients with PBC was associated with reversal or stabilization of fibrosis and cirrhosis. Click longitudinal biopsy studies have shown that patients who are not treated with, or have an inadequate response to, ursodeoxycholic acid UDCAthe current standard of care, are at significantly Assesment risk of fibrosis progression, liver failure, transplant and death.

Liver biopsy is not the standard of care in PBC and difficult to obtain in clinical trials. In this voluntary substudy of the POISE Phase 3 trial, paired biopsies adequate for analysis were obtained for 13 patients, all of whom had liver fibrosis Fuels Alternative Energy cirrhosis at baseline. A total of five serious adverse events in five patients were reported.

Liver Biopsy And Fibroscan

All serious adverse events were considered unlikely to be related, or not related, to OCA. Mean total bilirubin remained below baseline throughout the three-year open-label period.

Per EASL clinical guidelines, increasing bilirubin levels — even within the normal range — indicate progressive disease and are strongly associated with adverse clinical outcomes. The OCA mg titration group received OCA 5 mg for six months, after which dosing was increased to 10 mg based on tolerability and biochemical response.

The trial's primary endpoint was a reduction in ALP to below a threshold of 1.

About Primary Biliary Cholangitis Primary biliary cholangitis Histolobical is a rare, autoimmune cholestatic liver disease that puts patients at risk for life-threatening complications. PBC is primarily a disease of women, afflicting approximately one in 1, women over the age of If left untreated, survival of PBC patients is significantly worse than the general population.

Indications For Liver Biopsy And Histological Assessment Of The Liver

Contraindications Hypersensitivity to the active substance or to any of the excipients and complete biliary obstruction. Warnings and Precautions Elevations in alanine amino transferase ALT and aspartate aminotransferase AST have been observed in patients taking obeticholic acid. Clinical signs and symptoms of hepatic decompensation have also been observed. These events have occurred as early as within the first month of treatment.

Facilities

Liver-related adverse events have primarily been observed at doses higher than the maximum recommended dose of 10 mg once daily. In the post source setting, serious liver injury and death have been reported with more frequent dosing of obeticholic acid than recommended in patients with moderate to severe decreases in liver function. After initiation of therapy, all patients should be monitored for progression of PBC disease with laboratory and clinical assessment to determine whether dosage adjustment is needed.

Dosing frequency should be reduced for patients who progress to advanced disease i. The median time to onset of severe pruritus was 11, and 75 days for patients in the Ocaliva 10 mg, Ocaliva titration and placebo arms, respectively.]
