A narrative review of phase III and IV clinical trials for the pharmacological treatment of Huntington’s disease in adults

Review

作者: Alharthi, Mohammed S.

Huntington disease (HD) is a hereditary neurodegenerative condition characterized by progression of motor, cognitive, and psychiatric abnormalities. Despite the lack of definitive medications, current research efforts are actively assessing novel pharmaceutical interventions through phase III and IV clinical trials to mitigate the limited effectiveness of existing therapeutic approaches. The primary objective of these trials is to enhance symptom management and improve the overall quality of life for individuals diagnosed with HD. These trials show potential for development of further efficacious therapeutic interventions in future. To identify and provide details about medications tested in completed phase III and IV clinical trials for managing HD in adults. Publicly available and relevant phase III and IV trials registered at ClinicalTrials.gov analyzed. Usage of the trialed medications for HD reviewed. As of November 10, 2023, there were 242 phase III and IV clinical trials related to HD. Eight clinical trials from these met the inclusion criteria for the current study. The medications used in phase III and IV trials are minocycline, valbenazine, deutetrabenazine, tominersen, pridopidine (phase III), and memantine (phase IV). Evaluating phase III and IV clinical studies on HD highlights the importance of tailored approaches for each patient’s unique disease presentation. Current medications aim to manage HD symptoms, potentially improving outcomes and reducing disease progression risks. The growing emphasis on specific approaches reflects a better understanding of HD’s diverse symptoms, presenting opportunities for more effective and personalized treatment strategies.

Huntington's disease (HD) is an autosomal dominant disease caused by the expansion of cytosine-adenine-guanine (CAG) repeats in one copy of the HTT gene (mutant HTT, mHTT). The unaffected HTT gene encodes wild-type HTT (wtHTT) protein, which supports processes important for the health and function of the central nervous system. Selective lowering of mHTT for the treatment of HD may provide a benefit over nonselective HTT-lowering approaches, as it aims to preserve the beneficial activities of wtHTT. Targeting a heterozygous single-nucleotide polymorphism (SNP) where the targeted variant is on the mHTT gene is one strategy for achieving allele-selective activity. Herein, we investigated whether stereopure phosphorothioate (PS)- and phosphoryl guanidine (PN)-containing oligonucleotides can direct allele-selective mHTT lowering by targeting rs362273 (SNP3). We demonstrate that our SNP3-targeting molecules are potent, durable, and selective for mHTT in vitro and in vivo in mouse models. Through comparisons with a surrogate for the nonselective investigational compound tominersen, we also demonstrate that allele-selective molecules display equivalent potency toward mHTT with improved durability while sparing wtHTT. Our preclinical findings support the advancement of WVE-003, an investigational allele-selective compound currently in clinical testing (NCT05032196) for the treatment of patients with HD.

uniQure’s Regulatory Progress Sparks Optimism for ‘Desperate’ Huntington’s Space

iStock, wildpixel Analysts reacted positively to the news that uniQure is in alignment with the FDA on an accelerated approval pathway and on target for a Q1 2026 submission for its one-time gene therapy for Huntington’s disease—but patients have been here before. When uniQure CEO Matt Kapusta speaks to patients with Huntington’s disease, he hears a sense of “deep desperation.” Currently, people with Huntington’s—who number around 30,000 in the U.S.—are only offered drugs that can manage symptoms, which include movement abnormalities and cognitive impairment, “and those drugs really don’t work very well,” Kapusta told BioSpace . “There’s no disease-modifying treatments for them.” uniQure is hoping to change that. Last fall, the Massachusetts-based biotech announced alignment with the FDA on “key elements” of an accelerated approval pathway for AMT-130, a one-time gene therapy for Huntington’s. These elements include the use of natural history external controls as a comparator and change in the composite Unified Huntington’s Disease Rating Scale (cUHDRS) as an intermediate clinical endpoint. The cUHDRS measures the cognitive, motorial, psychiatric and behavioral symptoms of Huntington’s disease, Kapusta explained. For AMT-130, which is currently in Phase I/II studies, this would negate the need for another trial before uniQue can approval, and Stifel analysts at the time called the alignment “a best case scenario” for the company. On Monday, uniQure shared another regulatory update , communicating that it has “reached alignment with the FDA on several key components of the statistical analysis plan and chemistry, manufacturing and controls [CMC] information that will support” a biologics license application (BLA) in the first quarter of 2026. If successful, uniQure plans to launch the product before the end of next year. AMT 130 represents “the first potentially disease modifying treatment that could be available for [patients],” Kapusta said. Much of this, however, could hinge on three-year topline data which Kapusta expects to read out in September. At 24-months, a higher dose of AMT 130 slowed disease progression by 80% versus external controls, uniQure reported last July. The BLA will be based on this higher dose cohort, and the company will also analyze changes in neurofilament light—an accepted neurodegenerative biomarker—as supporting evidence. In September, Kapusta said the company will be seeking “consistency” with the two-year data. “If we’re able to demonstrate in treated patients at three years after a one-time administration of AMT 130 that there’s meaningful slowing of disease progression compared to this very closely matched external control cohort, I think that would be immensely powerful, and I think potentially supportive of a conditional approval,” he said. Typically, Kapusta said, early manifest patients—like those enrolled in uniQure’s study—lose around half a point on the cUHDRS scale per year. At two years, external controls in uniQure’s Phase I/II study had lost around one point, while patients treated with AMT 130 lost only 0.2 points. “If you extrapolate these things, what you’re really doing is you’re giving back to patients potentially years of their life, years of career development, years of weddings with their children, or birth of grandchildren, bar mitzvahs, sweet sixteens,” he said, “That’s what we’re hoping we can demonstrate in the third quarter.” uniQure’s news generated some buzz on Wall Street, with H.C. Wainwright assigning AMT-130 a 75% probability of success, “with anticipated approval in 2026E.” William Blair, meanwhile, called the regulatory update “favorable” both for uniQure and the broader gene therapy space, “as it demonstrates the FDA’s continued flexibility regarding registrational pathways for transformative therapies for rare diseases with a high unmet need.” Kapusta echoed this sentiment, saying that uniQure has not noticed a difference in terms of the company’s FDA interactions occurring before and after the administration turnover this year. “There’s still senior people that are attending our meetings from [CBER’s] office of therapeutic products . . . and we continue to see significant engagement and productive, constructive interactions with the FDA,” he added. While Kapusta said there has been a “knee jerk” reaction to past comments made by new Center for Biologics Evaluation and Research director Vinay Prasad regarding accelerated approvals, “It definitely seems that in comments he’s made to his own FDA staff, and comments that he’s made in other interactions, that he appears to be making it clear that he supports regulatory flexibility as it relates to innovative medicines in very high needs in rare diseases.” Indeed, on Tuesday, Prasad said the FDA plans to “rapidly make available” rare disease drugs, making use of surrogate endpoints to get promising medicines to patients before they clear the traditional efficacy bar for authorization. He made these remarks during a keynote speech organized by the National Organization for Rare Disorders. Prasad’s comments largely echo those of his boss. In April, during an interview with former Fox News journalist Megyn Kelly, FDA Commissioner Marty Makary introduced plans for a “conditional pathway” that would potentially allow for the approval of rare disease drugs based on a “plausible mechanism.” A Precedent of Disappointment As uniQure and analysts express optimism—albeit gaurded—the Huntington’s space has been here before, with myriad late-stage assets nearing the regulatory finish line only to falter. Five years ago, the community pinned its hopes on Roche’s antisense oligonucleotide tominersen . The ASO was designed to lower levels of the huntingtin ( HTT ) gene, particularly mutant HTT, which plays a crucial role in the development of the disease. Tominersen had shown great promise in Phase II, but in March 2021, Roche discontinued a Phase III trial of the drug after it ultimately failed to elicit higher efficacy than placebo, and actually led to worse outcomes when given more frequently. 2021 was a particularly bad year for the Huntington’s space, as Wave Life Sciences likewise shelved its two lead ASOs after they failed to elicit a therapeutic effect. But Huntington’s-focused companies aren’t giving up. Wave is back with a next-gen ASO, WVE-003, that targets a single-nucleotide polymorphism found on mutant HTT mRNA. Like uniQure, Wave is targeting accelerated approval for its candidate, having “initiated engagement” with regulators regarding a clinical development path, CEO Paul Bolno told BioSpace in November 2024. And at least on a global scale, uniQure has some competition to bring the first disease-modifying drug for Huntington’s to the market. In September 2024, Prilenia Therapeutics announced that the European Medicines Agency had accepted its marketing authorization application for pridopidine, a “highly selective and potent” agonist of the sigma-1 receptor, which is highly expressed in the brain and spinal cord and regulates several key processes that are commonly impaired in neurodegenerative diseases. Prilenia expects an opinion from the European regulator in the second half of this year, a company spokesperson told BioSpace in November 2024. A breakthrough can’t come soon enough for patients. Huntington’s is a dominantly transmitted neurodegenerative disorder and children of HD gene carriers have a 50% chance of inheriting the disease. Kapusta described a situation in which an individual has watched the degeneration of their parent—and possibly even acted as a caregiver. “If this is a patient that has been genetically confirmed, they know it’s 100% penetrative; they’re going to develop the disease, and they’re going to have to relive that movie as the main actor,” he said. “So right now, anything for them would give them hope.”

Roche is stopping patients on the low dose of its experimental Huntington’s drug tominersen, and will be transitioning them to the high dose following recommendations by an independent data monitoring committee. The Swiss pharma is studying tominersen, an antisense oligonucleotide, in a Phase 2 study of Huntington’s disease patients in the initial stages of the disease. The study is fully enrolled, and patients were receiving a 60 mg dose, 100 mg dose or placebo. Roche said the independent data monitoring committee did not raise concerns around safety or signs of symptom worsening with either dose in the Phase 2 study. That’s notable, because Roche stopped a previous Phase 3 study when tominersen appeared to make patients with later-stage disease worse off compared to those who got placebo. “The 100mg dose was found to be more likely than the 60mg dose to result in clinical benefit. Therefore for the remainder of the study only the 100mg dose will be tested against placebo, and the 60mg dose will be discontinued,” Roche’s neuroscience patient partnership leader Mai-Lise Nguyen wrote in a letter to patient advocates Thursday. The letter was shared publicly by Huntington’s Disease Youth Organization. Roche will switch patients assigned the 60 mg dose to the 100 mg dose, according to the letter. Patients receive one dose of tominersen every four months via spinal injection. The Phase 2 study was designed as a dose-finding study. However, this change does not mean Roche is bringing the high dose into next stages of development. The study remains blinded and is expected to complete in early 2026. Known as GENERATION HD2, the study includes patients before or at early-stage disease. The study was designed with a narrower patient population compared to the stopped Phase 3 study after Roche conducted a post-hoc analysis and identified a possible efficacy signal in the earlier population. Ionis Pharmaceuticals discovered tominersen, then partnered with Roche on the drug. Tominersen is meant to destroy the mRNA encoding the instructions for the huntingtin protein, in hopes of lowering levels of the mutant protein. In people with Huntington’s disease, the gene for that protein is mutated.
