UniQure Shares Crash 52% After FDA Signals Gene Therapy Risk
UniQure N.V. ($QURE) suffered one of its steepest falls on record, plunging from $10.14 to $4.82 on November 5 amid enormous volume of over 28 million shares—nearly 15 times its 3-month daily average, according to Nasdaq data. The catalyst: UniQure’s SEC filing late Monday warning that the FDA could issue a Complete Response Letter (CRL) for its hemophilia B gene therapy, etranacogene dezaparvovec. The company cited “substantial unresolved questions” in ongoing regulatory correspondence as the primary risk factor. Since the start of 2025, UniQure had already lost 38% of its market cap, but Tuesday’s single-day plunge erased over $400 million in value (Bloomberg, Nasdaq, company 8-K filing, 2025-11-04).
Gene Therapy Sector Faces Renewed Volatility After UniQure Rout
The UniQure stock collapse rippled through the biotech sector, with the Nasdaq Biotechnology Index dropping 1.6% by midday. Competing gene therapy developers like Sarepta Therapeutics ($SRPT) fell 4.9%, and bluebird bio ($BLUE) slumped 6.7%, illustrating renewed skepticism toward regulatory pathways for gene-editing and gene-replacement treatments (FactSet, 2025-11-05). Historically, high-profile gene therapy setbacks—such as Bluebird’s Zynteglo issues in 2022—have triggered multi-week volatility across the life sciences sector. The latest FDA scrutiny also comes as regulators toughen oversight on clinical efficacy and long-term safety, challenging near-term recovery in the gene therapy investment theme (stock market analysis; Reuters, 2025-11-05).
Investor Strategies: Managing Portfolio Risk After UniQure Downturn
With UniQure’s swift collapse and persistent regulatory overhang, investors holding gene therapy and biotech positions face a sharper risk landscape. Short-term traders may see heightened volatility opportunity across sector peers, but long-term holders should reassess weightings in small-cap therapeutics given unpredictable FDA timelines. Diversification into profitable large-cap biopharma—such as Amgen ($AMGN) and Gilead Sciences ($GILD)—can buffer portfolio shocks. Close monitoring of upcoming FDA decisions and trial milestones in gene therapy is advisable, as further negative verdicts could weigh on valuations across the sector.
