Huntington’s disease

UniQure plans to submit AMT-130 to the U.K.’s Medicines and Healthcare products Regulatory Agency in the third quarter of 2026 based on Phase 1/2 data showing a 75% slowing of disease—the same data the FDA has deemed unacceptable for a biologics license application.
Phase 2 data from PTC Therapeutics showed that the Novartis-partnered Huntington’s disease asset slowed progression by more than 50%. Analysts say the decision to initiate a last-stage trial reflects a lack of confidence in an accelerated FDA nod.
UniQure does not have to drill placebo burr holes in the skulls of patients with Huntington’s disease, an unnamed FDA senior official said on Thursday. Instead, the company would anesthetize them and put “one to three nicks” in their scalp.
While the FDA appears to be adamant that uniQure conduct a sham surgery–controlled Phase 3 trial before AMT-130 can be considered for approval, experts believe there is an alternate path forward for the therapy, perhaps even based on precedent from the recent drama surrounding Moderna’s mRNA flu vaccine.
Recent breakthroughs and three decades of progress in treating Huntington’s disease
In the midst of regulatory and political upheaval, biopharma’s R&D engine kept running, churning out highs and lows in equal parts. Here are some of this year’s most glorious clinical trial victories.
Investor optimism has waned as final minutes from uniQure’s pre-BLA meeting with the FDA convey that data from the company’s Phase I/II studies of AMT-130 are “unlikely” to provide the primary evidence to support a biologics license application.
A month after sparking optimism for patients with Huntington’s disease with highly positive data for AMT-130, uniQure revealed Monday that the FDA may be changing its tune on the evidence required for an approval application, a change of direction Stifel called “very challenging” for uniQure.
Last month, “historic positive results” from uniQure’s gene therapy snapped the Huntington’s community out of years of failure. As the biotech prepares to submit for FDA approval, BioSpace looks at four more candidates on the near horizon.
Pivotal results from uniQure’s gene therapy for Huntington’s disease have brought new light to patients who have known only disappointment in recent years—but one expert worries that communication of the results is creating “false expectations.”
