Gene therapy has had its commercial struggles in the past year. The cost to patients is in the millions and fewer are stepping forward for treatment than companies would like. While development continues in this game-changing field, some have struggled with regulatory authorities during development while others have just stepped away altogether.
Uniqure NV is regrouping after a surprise switcheroo by the havoc-beset U.S. FDA regarding phase I/II studies with AMT-130 vs. external control in Huntington’s disease (HD) – news of which pushed down the Lexington, Mass.-based firm’s shares (NASDAQ:QURE) Nov. 3 by $33.40, a loss of 49%, at the closing price of $34.29.
Uniqure NV rang the bell with a best-case scenario in the pivotal phase I/II study with AMT-130 for the treatment of Huntington’s disease, and shares of the Amsterdam-based firm (NASDAQ:QURE) closed Sept. 24 at $47.50, up $33.84, or 248%. The study met its prespecified primary endpoint, with high-dose AMT-130 turning up a statistically significant slowing of disease progression as measured by the composite Unified Huntington’s Disease Rating Scale at 36 months compared to a propensity score-matched external control.
Neurona Therapeutics Inc. has completed an upsized, oversubscribed $102 million financing round, the third company to do so in a month that’s only four days old. The privately held company’s lead asset is NRTX-1001, a regenerative cell therapy derived from human pluripotent stem cells.
The U.S. FDA has greenlit the first steps of Uniqure NV’s accelerated approval pathway for gene therapy AMT-130 to treat Huntington’s disease. The agency said data from the ongoing phase I/II studies compared to natural history external control are muscular enough to get the process going without having to dive into additional studies.
Uniqure NV shares (NASDAQ:QURE) closed July 9 at $6.67, up $2.89, or 76%, after the firm made public updated interim data including up to 24 months of follow-up findings from 29 treated patients enrolled in the ongoing U.S. and European phase I/II trials of AMT-130 for Huntington’s disease (HD).
On-again, off-again investor enthusiasm for Uniqure NV’s Huntington’s disease (HD) gene therapy AMT-130 got another boost as the company followed this summer’s news from phase I/II trials with additional interim data.

Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy characterized by recurrent seizures originating in the hippocampus and with sprouting of mossy fiber axons that contribute to new recurrent synaptic excitability in the dentate gyrus (DG).
Uniqure NV has received FDA clearance of its IND application for AMT-260, the company’s gene therapy candidate that represents a potential one-time administered approach to treating refractory mesial temporal lobe epilepsy (MTLE).
