A Phase 3, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Pridopidine in Participants With Huntington's Disease (HD)

The goal of this clinical trial is to learn if pridopidine can slow the clinical decline of Huntington's Disease (HD) in adult participants. It will also inform about the safety of pridopidine.
The main questions the study aims to answer are:
Does pridopidine slow the overall worsening of HD over 1 year? Does pridopidine slow the worsening of specific aspects of HD over 1 year, namely the clinical progression, the ability to perform daily life activities (functional capacity), the mind's ability to process information (cognition), working of the muscles (motor function), and quality of life?
Researchers will compare the drug pridopidine to a placebo (a look-alike substance that contains no drug) to see if pridopidine works better than placebo to treat HD. During the first year of the study, participants will have the same chance to receive either pridopidine or placebo.
Participants will:
Take 1 pridopidine or placebo capsule twice daily for 12 months. Visit the clinic 6 times within 1 year for checkups and tests.
All participants who complete this 1-year placebo-controlled study period will roll over into an additional 2-year study period during which all participants will receive pridopidine treatment, including participants who had received placebo during the first year. During this additional 2-year treatment period participants will visit the clinic a total of 6 times for checkups and tests.

Beyond motor symptoms: efficacy of pharmacotherapies on motor, functional, and cognitive domains in Huntington's disease - a systematic review

Review

Author: Teixeira, Amanda Gomes ; Wiprich, Melissa Talita ; Colonetti, Tamy ; Endler, Ana Thereza ; Bonan, Carla Denise ; Pereira, Wuesllen Dondossola ; Rosa, Maria Inês da ; Rico, Eduardo Pacheco ; Lodetti, Guilherme ; Pacagnan, Lucas de Oliveira ; Redivo, Henrique

INTRODUCTION:

Huntington's disease (HD) is a progressive neurodegenerative disorder characterized by motor, neuropsychiatric, cognitive, and peripheral alterations impairing functional capacity and quality of life (QoL). Pharmacotherapies, including dopaminergic and glutamatergic drugs, primarily target motor symptoms, while cholinergic modulators address cognitive decline. However, the literature lacks comprehensive reviews evaluating the combination of these three drug classes across a broad spectrum of clinical outcomes, extending beyond the total motor score (TMS).

OBJECTIVE:

This systematic review aimed to assess the efficacy of dopaminergic, glutamatergic, and cholinergic drugs on motor, functional, cognitive decline, and QoL in HD patients.

METHODOLOGY:

Following PRISMA guidelines, searches were performed in MEDLINE, Embase, Scopus, Web of Science, and the Cochrane Library until October 2025. Randomized clinical trials evaluating these three classes of drugs in adults with genetically confirmed HD were included. Primary outcomes were Unified Huntington's Disease Rating Scale (UHDRS) Total Motor Score (TMS), Total Functional Capacity (TFC), and cognitive performance. Secondary outcomes included the Independence Scale (IS) and QoL. Risk of bias was assessed using the Cochrane RoB 2 tool. Due to substantial heterogeneity, results were synthesized descriptively.

RESULTS:

From 32,746 studies, 15 were included in the final analysis. Findings showed that UHDRS TMS was improved with dopaminergics (tetrabenazine, deutetrabenazine, and pridopidine) and glutamatergic (riluzole) drugs. Only pridopidine treatment exhibited efficacy on UHDRS TFC, subsequently improving UHDRS IS. For QoL, deutetrabenazine treatment proved effective. In the UHDRS cognitive domain, tetrabenazine improved performance in the Stroop Color and Word test, while rivastigmine (cholinergic) improved verbal fluency.

CONCLUSION:

Dopaminergic, glutamatergic, and cholinergic drugs exhibit distinct efficacy profiles across various motor and non-motor UHDRS components. This positions them as therapeutic options for attenuating both the motor and non-motor symptoms in HD.

Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Pridopidine, a selective sigma-1 receptor agonist, was evaluated in Regimen D of the HEALEY ALS Platform Trial. Although the primary endpoint (ALS Functional Rating Scale-Revised (ALSFRS-R) total score accounting for survival at 24 weeks) was not met, a predefined subgroup analysis suggested slowed disease progression in ALS patients with definite and early disease (<18 months from onset). This report presents an exploratory analysis that further investigates pridopidine in rapidly progressing participants with definite/probable ALS and early-disease, where treatment effects may be more pronounced. Methods: The randomized, double-blind, placebo-controlled phase 2 trial assigned participants to pridopidine 45 mg bid or placebo, and placebo patients were shared across four trial regimens. The primary outcome was ALSFRS-R total score, with secondary outcomes assessing respiratory, bulbar, and speech functions. Results: Of 163 participants randomized to Regimen D, 72 met subgroup criteria (pridopidine: n = 37; shared placebo: n = 35). At week 24, pridopidine slowed ALSFRS-R total score decline (32%; Δ2.90, p = 0.03) and slowed decline of ALSFRS-R respiratory function (62%; Δ1.20, p = 0.03) and dyspnea (88%; Δ0.85, p = 0.005). ALSFRS-R-Bulbar function stabilized, with articulation and speaking rate declines reduced by 93% (Δ0.43, p = 0.0007) and 70% (Δ0.43, p = 0.002), respectively. Pridopidine was well-tolerated, with a safety profile comparable to placebo. All p values are nominal. Conclusion: Post hoc subgroup analysis suggests therapeutic benefits of pridopidine in patients that had definite/probable ALS and with early-disease progression, supporting further evaluation in a Phase 3 trial.

Emerging neurobiological targets in psychiatric treatment

Review

Author: Berk, Michael ; Govinnage, Janani ; Giorlando, Frank ; De Zoysa, Agampodi Ishan ; Narayanaswamy, J C ; Dodd, Seetal

Despite significant advancements in psychopharmacology, there are inadequate treatment options for many psychiatric disorders, including major depressive disorder, bipolar disorder, schizophrenia, and anxiety disorders. This review explores emerging neurobiological targets beyond conventional monoaminergic approaches, focusing on sodium channels, Neuropeptide Y (NPY), Neurokinin 1 (NK1) receptors, P2 × 7 purinergic receptors, Sigma-1 receptors, and Orexin. Recent evidence suggests that sodium channel modulators, such as evenamide, may offer therapeutic benefits for treatment-resistant schizophrenia by stabilizing glutamatergic neurotransmission. NPY-based therapies have potential in stress-related disorders, foreshadowing rapid anxiolytic and antidepressant effects through modulation of the stress response. NK1 receptor antagonists, although inconsistent in mood disorders, show promise in addiction treatment by reducing substance cravings. The P2 × 7 receptor, a key regulator of neuroinflammation, has been implicated in mood disorders, and its pharmacological inhibition may provide neuroprotective benefits. Additionally, Sigma-1 receptor agonists, including Blarcamesine and Pridopidine, have shown neuroprotective and cognitive-enhancing properties, making them attractive candidates for psychiatric and neurodegenerative disorders. Orexin receptor antagonists, such as suvorexant and seltorexant, have potential in mood disorders and substance dependence, highlighting the broader therapeutic applications of targeting the orexinergic system. While these emerging therapeutic targets hold promise, challenges remain in translating preclinical findings into effective clinical applications. Large-scale, placebo-controlled trials are necessary to establish their efficacy and safety. The identification of biomarkers for patient stratification will be critical in the hitherto elusive goal of developing precision medicine approaches. Targeted pharmacological interventions offer a path toward more effective, well-tolerated, and potentially individualized treatment options for patients with severe mental illness.

About Huntington’s Disease 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 genei, and each child of a parent with HD has a 50 percent chance of developing the diseaseii. Across the world an estimated 100,000 people have HDiii,iv, with an additional 300,000 people at risk of developing HDv,vi. It is usually diagnosed between the ages of 30 and 50, 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 15 to 20 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. The only currently available treatments for HD focus on symptomatic relief and palliative care, with nothing impacting measures of overall progression. A potential registrational Phase 3 study of pridopidine in early to mid-stage HD is planned to commence in the second quarter of 2026. About Prilenia Prilenia is a private biopharmaceutical company driven by an unwavering commitment to scientific excellence and accelerating progress for people affected by Huntington’s disease (HD), amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders. Our mission is simple but urgent: to develop and provide sustainable access to transformative medicines for people affected by devastating neurodegenerative diseases.

Boehringer appoints pharma veteran for corporate affairs post; BlueRock CSO heads for the exit

→ Boehringer Ingelheim has brought in Christie Bloomquist as SVP, corporate affairs, US human pharma, and she’ll be president of the Boehringer Cares Foundation. Peer Review informed you about her move to Astellas in 2023, and she had been VP, US strategy and government affairs at the Japanese drugmaker since January 2025. She was also in charge of US corporate and government affairs at AstraZeneca . “What drew me in was how both comfortable and challenged I felt with everyone I met during the interview process,” Bloomquist wrote in a LinkedIn post . “These are people I genuinely want to work with, in a place where I know I can contribute.” → In another LinkedIn discovery, Stefan Irion is stepping down as CSO of Bayer ’s BlueRock Therapeutics . Irion was promoted to this position in 2023 and started working at BlueRock “in its earliest days, when the idea was audacious and the roadmap mostly lived on whiteboards and in late‑night conversations,” he wrote . BlueRock has moved into Phase 3 with bemdaneprocel , a cell therapy to treat Parkinson’s disease. → Not only did Incyte get a pair of Phase 3 wins in nonsegmental vitiligo this week, its search for a CFO is over . Suky Upadhyay replaced Dan Florin as CFO of Zimmer Biomet in 2019 and would tack on the role of EVP, global operations. Upadhyay is currently on the board of directors at Vertex and led global financial operations at Bristol Myers Squibb from 2016-19. You may recall that Christiana Stamoulis left Incyte in September to become CFO at Mallinckrodt , which is now known as Keenova after the merger with Endo . Zimmer Biomet said that Paul Stellato will fill in as interim finance chief. → Shortly before landing on the Nasdaq in a $255 million IPO this week, Seaport Therapeutics snagged neuroscience veteran Sharon Mates for its board. The mid-stage neuroscience biotech now has the former chair and CEO of Intra-Cellular Therapies to help guide it toward commercialization. Mates led Intra-Cellular all the way from the ground up, put it on a commercial footing, and took it to a $14.6 billion exit to Johnson & Johnson . → Jennifer Smoter said in a LinkedIn post that she’s “thrilled to return to the biopharmaceutical industry” as chief communications & governance officer at Takeda . Smoter led the communications team during her four and a half years with UnitedHealth Group , and she was chief external affairs & communications officer at Intellia Therapeutics . As part of its multiyear restructuring , Takeda recently ended its partnership with Denali Therapeutics . The Japanese pharma reports its FY2025 earnings on May 13. → A spokesperson tells Peer Review that AI-focused startup Basecamp Research has tapped Richard Pearce as CBO after raising the curtain on its Trillion Gene Atlas project last month. Basecamp plucked him from Biogen , where he was head of business development, strategy and portfolio management in the back half of his 11-year career with the company. Earlier, Pearce served as business and operations director of the Biodevelopment Centre at Merck KGaA . “By training foundation models on the largest evolutionary dataset ever assembled, Basecamp is building something fundamentally new for biology,” Basecamp CEO Glen Gowers said in a statement. “Richard brings a rare combination of deep pharma experience and first-principles thinking — exactly what’s needed to translate this technology into real-world impact.” → Boston-based mRNA startup Strand Therapeutics has hired its first-ever CFO. Kunal Bhatia started his career at Credit Suisse and Jefferies , and has been a managing director in the healthcare investment banking groups at Oppenheimer and TD Cowen . Kinnevik , Regeneron Ventures , Amgen Ventures and Eli Lilly participated in Strand’s $153 million Series B last summer. → Coy Stout is retiring after 30 years in industry, with the last year and a half as executive director of US patient support at AstraZeneca. He’s had stops along the way at Lykos , Brii Biosciences and nearly two decades at Gilead . “While I expected this part of my journey as a market access leader to last a little bit longer,” Stout wrote on LinkedIn, “life has a way of making priorities clear. I’m stepping away from the industry to focus on work-life balance and on one of the most important roles of my life: being a spouse and caregiver to someone living with advancing Parkinson’s disease.” → Now under the direction of ex- bluebird bio boss Andrew Obenshain , Inventiva has welcomed three new execs, including former CureVac finance chief Axel-Sven Malkomes . He’ll be the first person besides Jean Volatier to step into the CFO slot in the company’s history, and Volatier will still have a presence at Inventiva as EVP of finance & corporate social responsibility. Meanwhile, Inventiva has recruited Susan Coles as chief legal officer and Pamela Herbster as chief people officer. Coles has already been general counsel at Inventiva twice, and Herbster was elevated to chief people & experience officer at Sage before Supernus bought the embattled drug developer for $561 million. → Newly public Avalyn Pharma has recruited Adam Golden as general counsel and head of business development, and Frank Salisbury as SVP of commercial. Golden comes to Avalyn from London-based law firm Freshfields , where he was a partner and global head of life sciences. Salisbury is a Sage and Genentech alum who spent the last four years with PureTech Health as head of commercial and product strategy. → Lis Leiderman has returned to Peer Review for her fourth CFO job this decade. Her LinkedIn page indicates that she succeeded Rob Lauzen at Dutch neuro biotech Prilenia Therapeutics in March. Leiderman worked for Decibel Therapeutics (2020-22), Atsena Therapeutics (2022-23) and Dewpoint Therapeutics (2024-25), and she sits on the board of directors at Autolus Therapeutics . Prilenia’s only candidate is an S1R agonist called pridopidine for ALS and Huntington’s disease. → Sanofi Genzyme vet Michael Panzara has replaced co-founder Andreas Muehler as CMO of Immunic . Panzara had been CMO of Blackstone ’s Neurvati Neurosciences and its subsidiary GRIN Therapeutics , which collected $50 million upfront from Angelini Pharma for the ex-North America rights to radiprodil . He also vaulted to CMO and head of therapeutics discovery & development during a six-year run at Wave Life Sciences . → Radiotherapy shop Convergent Therapeutics has selected Merck vet Andrew Davis as chief business and strategy officer. Davis concluded his stint as CBO of Dynavax after it was purchased by Sanofi for $2.2 billion, and he held that same role at Ironwood Pharmaceuticals . → Christian Schade has been named chairman of the board at German biotech CatalYm . Since selling Halda Therapeutics to J&J for north of $3 billion last fall, Schade joined Frazier Life Sciences as a senior advisor. After a stint as CEO of Aprea Therapeutics , he landed at Flagship Pioneering in early 2023 as a growth partner. → Marea Therapeutics CEO Josh Lehrer has locked up a spot on the board of directors at Fulcrum Therapeutics . With a series of roles over a six-year period at Global Blood Therapeutics , including CMO, his input on Fulcrum’s lead sickle cell asset pociredir should be beneficial. Lehrer ran Graphite Bio until it merged with Lenz Therapeutics . → Deborah Birx ’s bacteriophage biotech Armata Pharmaceuticals has appointed Daniel Gilmer to its board of directors. Gilmer was elevated to senior director, commercial quality US team lead at Pfizer last year. → In other boardrooms, Raymond Dwek will retire at United Therapeutics , but he’ll stay on the scientific advisory board; Boehringer Ingelheim’s Lykke Hinsch Gylvin is headed to ProQR ; Troy Cox and Alumis CEO Martin Babler are in line to replace Robert Malenka and Jim Trenkle at Maplight Therapeutics , according to an SEC filing ; Santhera has added ex- Idorsia CEO Srishti Gupta ; and InduPro Therapeutics CEO Prakash Raman has picked up a board seat at Olema Oncology .
