Pridopidine in early-stage manifest Huntington's disease: a phase 3 trial.

Huntington's disease (HD) is a rare, neurodegenerative disorder for which only symptomatic treatments are available. The PROOF-HD study was a randomized, double-blind, placebo-controlled phase 3 trial evaluating the efficacy and safety of pridopidine, a selective Sigma-1 receptor agonist, in HD. The primary and key secondary endpoints, change in total functional capacity (TFC) and composite Unified Huntington's Disease Rating Scale (cUHDRS) score at week 65, were not met in the overall population.

Antidopaminergic Medications and Clinical Changes in Measures of Huntington's Disease: A Causal Analysis.

Background: Antidopaminergic medications (ADM) are often used for symptom management of Huntington's disease (HD). Evidence from past research suggests that ADMs are associated with worse clinical outcomes in HD, but their impact on various domains remains underexplored.

Objective: We used causal inference analysis to understand the impact of ADM use on measures of clinical progression in HD across multiple domains over 2 years.

The Safety Profile of Pridopidine, a Novel Sigma-1 Receptor Agonist for the Treatment of Huntington's Disease.

Background: Huntington's disease (HD) is a rare, fatal, chronic progressive neurodegenerative disorder with a significant unmet medical need for effective treatments. Pridopidine is a novel, first-in-class, highly selective and potent sigma-1 receptor (S1R) agonist in development for HD. Pridopidine has been extensively studied in adult HD across the full spectrum of disease severity and age ranges, and its safety profile has been characterized in approximately 1600 participants across multiple studies and a broad range of doses.

Antidopaminergic medications in Huntington's disease.

Huntington's disease (HD) is a progressive neurodegenerative disorder marked by motor, cognitive, and behavioral impairments. Antidopaminergic medications (ADMs), such as VMAT2 inhibitors and antipsychotics, are commonly used to manage HD motor disturbances and behavioral disorders. For patients and caregivers, ADMs are an important tool for managing symptoms that negatively affect daily life.
