UniQure reported a regulatory update on November 3, 2025, that sent shares plummeting in premarket trading. The biotech company disclosed that the Food and Drug Administration has changed its position on data supporting the company’s Huntington’s disease therapy.

The FDA no longer agrees that Phase I/II study data for AMT-130 is adequate to support a Biologics License Application. This represents a reversal from the agency’s previous stance.

AMT-130 is an investigational gene therapy designed to treat Huntington’s disease. The FDA granted the therapy Breakthrough Therapy designation earlier this year.

The regulatory update came following a pre-BLA meeting between UniQure and the FDA. The company had been comparing its Phase I/II data against an external control group.
