FDA Feedback on uniQure's Gene Therapy: The FDA has expressed concerns regarding uniQure N.V.'s investigational gene therapy for Huntington's disease, AMT-130, indicating that the data from Phase 1/2 studies may not be sufficient for a Biologics License Application (BLA) submission.
Impact of FDA Leadership Changes: The absence of key FDA officials during the recent meeting, particularly Nicole Verdun, who was placed on administrative leave, has raised questions about the regulatory pathway for AMT-130 and contributed to a downgrade of uniQure's stock rating.
Regulatory Scrutiny on Gene Therapies: The FDA's comments suggest a tightening of regulations for gene and cell therapy programs, which could negatively affect other companies in the sector that have relied on similar trial designs.
Market Reaction: Following the FDA's feedback, uniQure's stock price fell by nearly 11%, reflecting investor concerns over the uncertainty surrounding the timing of the BLA submission and the overall regulatory environment for gene therapies.

Kyverna's miv-cel Shows Significant Improvement in Stiff Person Syndrome
- Clinical Trial Results: Kyverna Therapeutics' miv-cel demonstrated significant clinical improvements in the KYSA-8 registrational trial for Stiff Person Syndrome (SPS), with a 46% improvement in T25FW at 16 weeks and 81% of patients achieving clinically meaningful functional gains, marking a fundamental shift in treatment paradigms.
- New Immunotherapy Option: All 26 patients discontinued chronic immunotherapies after a single dose of miv-cel, showcasing the therapy's potential to enhance patient quality of life and possibly become the first approved treatment for SPS.
- Good Safety Profile: Miv-cel exhibited a favorable safety profile with no high-grade cytokine release syndrome or neurotoxicity observed, and most adverse events were manageable, indicating its suitability for outpatient administration and enhancing its market prospects.
- Future Outlook: Kyverna plans to submit a Biologics License Application (BLA) and is confident in miv-cel's potential for other neurological autoimmune diseases, suggesting that this therapy may play a significant role in broader indications.
