Obeticholic acid (OCA) received accelerated approval for treating patients with primary biliary cholangitis in whom ursodeoxycholic acid failed, based on a surrogate endpoint of reduction in ALP. Analysis of the long-term safety extension with 2 external control groups demonstrated a significant increase in event-free survival in OCA-treated 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.

Article Synopsis
  • Obeticholic acid (OCA) was evaluated in the COBALT trial for its effectiveness in treating primary biliary cholangitis (PBC), showing mixed results in the randomized controlled trial (RCT) compared to external controls.
  • In the RCT, similar rates of severe outcomes occurred between OCA and placebo groups, but issues like unblinding influenced the results; however, analysis adjustments gave OCA an advantage.
  • The external control group indicated that OCA significantly lowered the risk of negative outcomes, highlighting its potential benefits for patients with PBC and endorsing the use of real-world data in clinical research.
