  • Measurements of total and mutant HTT protein in the cerebral spinal fluid of the four patients were highly variable and inconclusive.
  • A clinical update on the low-dose cohort of ten patients, primarily focused on safety, is expected in Q2 of 2022.
  • Full safety and efficacy data from the first two cohorts are expected in 1H of 2023 after all patients in the higher-dose cohort have achieved one year of follow-up.
  • The U.S. Phase 1/2 trial of AMT-130 in a planned 26 patients with early manifest Huntington's disease, split into a ten patient, low-dose cohort followed by a 16 patient, higher-dose cohort. 
  • The multi-center trial consists of a blinded 12-month core study period followed by unblinded long-term follow-up for five years. 
  • UniQure also plans to initiate a third cohort in 2H of 2022 to explore alternative stereotactic navigation systems to simplify the placement of catheters for infusions of AMT-130. 
  • Price Action: QURE shares are down 29.30% at $20.34 during the market session on the last check Thursday.
