A phase 2, adaptive randomized, double-blind, placebo-controlled, multicenter, 52-week study of HM15211 in patients with biopsy-confirmed non-alcoholic steatohepatitis - Study design and rationale of HM-TRIA-201 study.

Non-alcoholic steatohepatitis (NASH) is a multifactorial disease with an increasing prevalence worldwide due to the obesity pandemic. HM15211 (efocipegtrutide), a novel, long-acting glucagon-like peptide-1/glucagon/glucose-dependent insulinotropic polypeptide triple incretin agonist has shown promising efficacy in in vitro, preclinical rodent models of NASH and phase 1 studies with manageable toxicity. Though liver biopsy is recommended for grading and staging of NASH, its invasive nature necessitates innovative approaches in clinical trials that decrease the burden of patients otherwise subjected to this invasive procedure.

Differential Associations of Circulating MicroRNAs With Pathogenic Factors in NAFLD.

Nonalcoholic fatty liver disease (NAFLD) is a heterogeneous disease driven by genetic and environmental factors. MicroRNAs (miRNAs) serve as pleiotropic post-transcriptional regulators of cellular pathways. Although several miRNAs have been associated with NAFLD and fibrosis, there are limited studies in humans examining their differential association with pathogenic factors or histological features of NAFLD.

Standardisation of diet and exercise in clinical trials of NAFLD-NASH: Recommendations from the Liver Forum.

Lifestyle modification is the foundation of treatment recommendations for non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). The design of clinical trials in NASH may be impeded by the lack of a systematic approach to identify and evaluate how lifestyle changes and/or modifications influence clinical trial outcomes and associated endpoints. Furthermore, there are additional uncertainties regarding the methods that can be utilised to better characterise and quantify lifestyle variables - which can influence disease activity and alter trial endpoints - to allow for comparisons of trial outcomes across different phases of research and/or within drug-classes.

Clinical endpoints and adaptive clinical trials in precirrhotic nonalcoholic steatohepatitis: Facilitating development approaches for an emerging epidemic.

Due to the increasing prevalence of nonalcoholic steatohepatitis (NASH) and its associated health burden, there is a high need to develop therapeutic strategies for patients with this disease. Unfortunately, its long and asymptomatic natural history, the uncertainties about disease progression, the fact that most patients are undiagnosed, and the requirement for sequential liver biopsies create substantial challenges for clinical development. Adaptive design methods are increasingly used in clinical research as they provide the flexibility and efficiency for identifying potential signals of clinical benefit of the test treatment under investigation and make prompt preplanned adaptations without undermining the validity or integrity of the trial.
