uniQure stock crashes as Huntington’s gene therapy data weaken
uniQure's stock fell 41% after its Huntington’s disease gene therapy, AMT-130, showed a 44% slowing of disease progression at 48 months, missing statistical significance. Despite this, analysts and the company remain optimistic due to a strong secondary endpoint and questions about the primary endpoint's comparator data. The FDA's response to the new data remains uncertain.
