Abstract

Introduction: Huntington's Disease (HD) is a progressive fatal neurodegenerative disease with an unmet need for disease-modifying therapies. Neuroinflammation, particularly astrogliosis, plays a crucial role in the pathogenesis of HD and modulation of this damaging activity and its downstream effects presents a promising therapeutic avenue. Pepinemab, a semaphorin 4D (SEMA4D) blocking antibody, has the potential to serve this purpose.

Areas covered: We review the proposed mechanisms of action of pepinemab, published safety and efficacy results from the 'SIGNAL' Phase 2 trial in HD and supporting data from a Phase 1 trial in multiple sclerosis (MS).

Expert opinion: Pepinemab's potential to reduce reactive gliosis and inflammation is a novel mechanism of action (MOA) that may be effective as a standalone therapy as well as one that may complement other strategies to reduce toxic disease associated processes. Pepinemab has demonstrated a favorable safety profile and treatment benefits in fluid biomarkers, imaging endpoints, and measures of cognitive function that encourage continued development in HD and other neurodegenerative diseases.

期刊介绍： Expert Opinion on Investigational Drugs (ISSN 1354-3784 [print], 1744-7658 [electronic]) is a MEDLINE-indexed, peer-reviewed, international journal publishing review articles and original papers on drugs in preclinical and early stage clinical development, providing expert opinion on the scope for future development. The Editors welcome: Reviews covering preclinical through to Phase II data on drugs or drug classes for specific indications, and their potential impact on future treatment strategies Drug Evaluations reviewing the clinical and pharmacological data on a particular drug Original Research papers reporting the results of clinical investigations on agents that are in Phase I and II clinical trials The audience consists of scientists, managers and decision-makers in the pharmaceutical industry, and others closely involved in R&D.
