Recruitment in the EU is expected to commence this month, joining currently recruiting sites in the US and UK, with Canada to follow.Designed to evaluate the efficacy and safety of pridopidine (administered as an oral capsule twice a day), and to generate data for regulatory evaluation, the global, approximately 400-participant, randomized, double-blind, placebo-controlled PRECISE-HD study will assess the clinical effect of the investigational treatment on disease progression, functional capacity, motor function, cognition, speech and quality of life.This advertisement has not loaded yet, but your article continues below.“The initiation of PRECISE-HD in Europe marks a milestone for the Huntington’s disease research community. This confirmatory Phase 3 study has been designed to build on learnings from previous research and to rigorously evaluate the efficacy and safety of pridopidine in people living with HD. As investigators, we look forward to working with participating centers and the HD community to generate robust evidence that can help us better understand the potential role of the study treatment in HD,” said Dr. Ralf Reilmann, Principal Investigator and member of the PRECISE-HD Steering Committee.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

We welcome the involvement of European centers in PRECISE-HD and the continued focus on outcomes that reflect the realities and priorities of people living with HD and their families,” said Astri Arnesen, President of the European Huntington Association.“At Ferrer, putting our purpose into practice also means taking on complex scientific challenges, while recognizing the uncertainty inherent in research. The authorization to initiate PRECISE-HD in participating EU Member States is a further step in our work with Prilenia. We approach that work with a clear sense of responsibility: to conduct research with integrity and let the evidence lead the way,” said Oscar Pérez, Chief Scientific Officer at Ferrer.Huntington’s disease (HD) is a rare, inherited, autosomal dominant, neurodegenerative disease that results in functional, motor, cognitive and behavioral symptoms, and ultimately leads to death. HD is caused by a mutation in the huntingtin (HTT) geneii, and each child of a parent with HD has a 50 percent chance of developing the diseaseiii.Across the world an estimated 100,000 people have HDiv, with an additional 300,000 people at risk of developing HDv,vi. It is usually diagnosed between the ages of 35 and 55viiviii, although HD can occur at any age, including in children and young adults (known as juvenile onset HD or JHD). The disease progresses slowly over 10 to 30ix years, with patients slowly losing their ability to work, communicate, manage day-to-day life and take care of themselves. This increasing disability leads to full reliance on a caregiver and, ultimately, death.This advertisement has not loaded yet, but your article continues below.The only currently available treatments for HD focus on symptomatic relief and palliative care, with no approved therapies shown to impact measures of overall disease progression.Pridopidine is an investigational highly selective, oral sigma-1 receptor (S1R) agonist. S1R has been shown to play a role in stimulating multiple neuroprotective pathways impaired in neurodegenerative diseases, such as Huntington’s disease (HD) and amyotrophic lateral sclerosis (ALS)x.In clinical studies to date, pridopidine (taken as an oral capsule twice a day) has shown a generally favorable safety and tolerability profile, with data from more than 1,600 people (mostly from HD studies), some of whom have received active treatment for up to seven yearsxi.Pridopidine is currently in late-stage clinical development for HD and ALS. It has Orphan Drug Designation in HD and ALS in the US and EU, and FDA Fast Track designation in the US for the treatment of HD. These designations do not imply that pridopidine has been approved or that safety and efficacy have been established.About the PRECISE-HD StudyPRECISE-HD (Pridopidine Phase 3 Study to Establish Clinical Impact and Safety in Huntington’s Disease) is a confirmatory, global, 400-participant, randomized, double-blind, placebo-controlled study designed to further evaluate the efficacy and safety of pridopidine, an investigational medicinal product, in people living with Huntington’s disease (HD), from early to mid-stage disease (TFC 7-13).Focused on generating data to further support regulatory evaluation, the study will assess the clinical effect of pridopidine on disease progression, functional capacity, motor function, cognition, speech and quality of life. It incorporates learnings from prior research, advice and input from the HD patient and research community, and regulatory authorities.PRECISE-HD comprises two consecutive stages: a 52-week placebo-controlled stage, with participants randomized to receive either pridopidine or placebo on a 1:1 basis, followed by a 104-week open-label extension stage in which all eligible participants will receive pridopidine. The primary endpoint is the change from baseline to Week 52 in the combined Unified Huntington’s Disease Rating Scale (cUHDRS) score.PRECISE-HD will be undertaken at up to 75 sites globally, including sites in the United States, European Union, United Kingdom and Canada.
