Hepatic real-world outcomes with obeticholic acid in primary biliary cholangitis (HEROES): A trial emulation study design.

Background And Aims: Primary biliary cholangitis (PBC) is a rare, progressive liver disease. Obeticholic acid (OCA) received accelerated approval for treating patients with PBC in whom ursodeoxycholic acid (UDCA) failed, based on a surrogate endpoint of reduction in alkaline phosphatase. Analysis of the long-term safety extension with 2 external control groups demonstrated a significant increase in event-free survival in OCA-treated patients.

Common Variants in the Gene with Unclear Pathogenicity as the Cause of Oculocutaneous Albinism in a Cohort of Russian Patients.

oculocutaneous albinism (OCA) is a hereditary impairment of skin, hair, and eye pigmentation. The most common form of albinism is autosomal recessive albinism, caused by mutations in the gene, accounting for approximately 40-50% of all cases of the disease in European populations. Common hypomorphic variants in the gene could lead to a mild form of albinism in a compound heterozygous state with a pathogenic variant.

COBALT: A Confirmatory Trial of Obeticholic Acid in Primary Biliary Cholangitis With Placebo and External Controls.

Introduction: Obeticholic acid (OCA) treatment for primary biliary cholangitis (PBC) was conditionally approved in the phase 3 POISE trial. The COBALT confirmatory trial assessed whether clinical outcomes in patients with PBC improve with OCA therapy.

Methods: Patients randomized to OCA (5-10 mg) were compared with placebo (randomized controlled trial [RCT]) or external control (EC).

[Possibilities of effective interaction in the system pharmacovigilance at registration of medicinal undesirable reactions at patients of the senior age groups.].

In recent years, complications of drug therapy are an important medical problem. Data on adverse drug reactions (ADR) in patients of older age groups were analyzed. The object of the study was notification cards for unwanted reactions received from medical organizations of the Irkutsk region for period 2009-2020 years.
