Also known as: Huntington's, Huntington’s
Huntington's disease is an autosomal dominant neurodegenerative disorder characterized by progressive motor dysfunction, cognitive decline, and psychiatric symptoms. It is caused by CAG repeat expansion in the HTT gene and typically manifests in mid-adulthood. Disease progression leads to severe disability over time.
The FDA has reversed its earlier rejection of UniQure's Huntington's disease therapy AMT-130, accepting existing trial data for accelerated review. The company plans to submit a marketing application in Q3 2026, ending a dispute over sham surgery requirements.
The FDA agreed uniQure's existing trial data could support an accelerated approval filing for Huntington's therapy AMT-130, a reversal from earlier positions. Meanwhile, UK-based Harness Therapeutics selected HRN001 as its lead experimental candidate, targeting the FAN1 protein to address somatic expansion of Huntington's-causing genetic repeats.
Novartis introduced new long-term social impact and sustainability targets covering access, global health, emissions, waste and water. The plan includes a 2030 access goal and net-zero across the value chain by 2040.
The FDA said uniQure’s Phase I/II data for Huntington’s disease gene therapy AMT-130 are not adequate for a marketing application. The agency recommended a new randomised, double-blind, sham surgery-controlled study.
UniQure shares fell sharply after FDA comments appeared to raise concerns about the invasive delivery method for Huntington's disease therapy AMT-130. The company had planned a 2026 BLA filing after Phase I/II data showed a 75% slowing of disease progression at 36 months.
A phase 3 clinical trial has launched for pridopidine as a potential ALS treatment, while AI research identified 18 FDA-approved drugs that may extend survival. Separate studies found a promising three-drug combination for sporadic ALS using new cell models.
Huntington's disease provides neuroscience with a uniquely clear genetic model for studying brain disorders, featuring a single identifiable mutation and predictable disease progression. The condition serves as a testing ground for cutting-edge therapies and raises fundamental questions about brain regeneration. Its scientific clarity combined with a united patient and research community makes it an invaluable resource for advancing neurological understanding.
Sarepta Therapeutics received FDA feedback supporting supplemental applications for AMONDYS 45 and VYONDYS 53, while New Zealand approved a Phase 1 trial for Huntington's Disease candidate SRP-1005. The company faces significant share price declines despite these developments, with analysts showing wide disagreement on valuation targets ranging from $5 to $80.
uniQure disclosed the FDA will not accept Phase I/II data alone for AMT-130 approval, causing shares to drop 49%. The company held regulatory meetings and reported $622.5 million in cash while investors face an April 13 class action deadline.
The FDA has denied or discouraged at least eight drug applications in the past year, including treatments for rare diseases, raising concerns about regulatory consistency and the future of experimental therapies.
