LEXINGTON, Mass. and AMSTERDAM, Aug. 08, 2022 (GLOBE NEWSWIRE) -- uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today reported its financial results for the second quarter of 2022 and highlighted recent progress across its business.

“We continued to make strong progress across all of our programs highlighted by encouraging data from the lower-dose cohort in our Phase I/II study of AMT-130 and the advancement of the U.S. and European regulatory reviews for the marketing applications for etranacogene dezaparvovec in hemophilia B,” stated Matt Kapusta, chief executive officer at uniQure.  “Our manufacturing, CMC and Quality teams are working tirelessly to produce commercial launch supplies and also to ensure successful pre-approval site inspections, which are expected to be completed in the third quarter of this year. We also are very pleased to have recently received notification that GMP certification will be provided to our Lexington manufacturing facility by the European authorities.”

“In July, we reported to the health authorities suspected unexpected severe adverse reactions in three of the 14 patients treated with the higher dose of AMT-130,” he continued. “While these patients have fully or substantially recovered, and no clear root cause has yet been identified, we believe it’s prudent to temporarily delay additional higher-dose procedures until we put additional monitoring and treatment plans in place and complete our safety review early in the fourth quarter of 2022. The delay is not expected to impact any future lower-dose procedures, as no serious adverse events related to AMT-130 have been reported in any of the additional 12 patients treated at the lower dose, and no impact is expected on the timing of previously guided data read-outs in 2023, including the presentation of one to two-year follow-up on both low and high-dose cohorts in the second quarter of 2023.”

Recent Updates

• AMT-061 for the treatment of hemophilia B
  
  
  • In May 2022, the Company’s global commercialization partner, CSL Behring, announced that the BLA for etranacogene dezaparvovec was accepted by the Food and Drug Administration (FDA) for priority review. This follows the MAA submission by CSL Behring which was validated by the EMA in March 2022.
    
    
  • In July 2022, CSL Behring was notified by the Committee for Advanced Therapies (CAT) in Europe that they will be unable to complete their review in accordance with the accelerated assessment timetable and will now switch to a standard review procedure. In the United States, the BLA remains under Priority Review at this time. In accordance with the Company’s commercialization and license agreement, CSL Behring is solely responsible for all regulatory activities, including filings and agency interactions associated with etranacogene dezaparvovec.
    
    
  • In July 2022, following a comprehensive multi-day facility inspection, the European Medicines Agency notified the Company that Good Manufacturing Practice (GMP) certification can be issued for the Company’s Lexington manufacturing site to produce commercial supply of etranacogene dezaparvovec.  
    
    
• AMT-130 for the treatment of Huntington’s disease
  
  
  • In June 2022, initial 12-month observations were announced on the lower-dose cohort of the double-blinded and randomized U.S. Phase I/II study of AMT-130 for the treatment of early-stage Huntington’s disease.
    
    
    • At 12 months of follow-up on these patients, the lower-dose was generally well-tolerated with no serious adverse events related to treatment. In the four treated patients with evaluable data from this cohort, mean levels of mutant Huntingtin protein (mHTT) in the cerebral spinal fluid (CSF) declined at all timepoints compared to baseline and decreased by 53.8% at 12 months of follow-up. In the three control patients with evaluable data, mean levels of mHTT showed an increase compared to baseline at one, three, six and nine months of follow-up, and decreased by 16.8% at 12 months of follow-up.
      
    • In the six treated patients in the lower-dose cohort, measurements of neurofilament light chain (NfL) in the CSF, a biomarker of neuronal damage, initially increased as expected following the AMT-130 surgical procedure and declined thereafter, nearing baseline at 12 months of follow-up. At 12 months, mean NfL showed an 8% increase compared to baseline. Two of the six treated patients were at or below baseline at 12 months of follow-up, with an additional patient below baseline at 15 and 18 months of follow-up.

• In mid-July, the Company reported to the appropriate regulatory agencies suspected unexpected severe adverse reactions (SUSARs) in two patients that were treated with the higher-dose of AMT-130 at a single clinical site in the European Phase Ib/II study. Both patients presented with localized inflammatory responses and other related symptoms approximately one to two weeks after their procedures. A third patient, who had previously been treated with the higher-dose of AMT-130 in the U.S. during March 2022, experienced severe headache and other related symptoms soon after AMT-130 administration that was initially deemed by the investigator as not related to AMT-130 but related to the procedure. Upon further review and discussion with the clinical trial’s independent Data Safety Monitoring Board (DSMB) following the events observed in the European study, the Company has reclassified and reported the patient reaction in the U.S. trial as a SUSAR. All three patients have fully or substantially recovered after treatment and have been released from the hospital.
  
  
  • At this time, the DSMB does not view these findings as a dose-limiting toxicity. The DSMB has recommended temporarily delaying higher-dose enrollment pending a safety review, which is expected to take place early in the fourth quarter of 2022. The DSMB is permitting continued enrollment at the lower-dose of AMT-130, and the Company expects to begin crossing over control patients from the U.S. study at this dose in the third quarter of 2022.
    
  • No impact is expected on the timing of previously guided data read-outs in 2023. In the U.S. Phase I/II study, all 26 patients in the first two dose cohorts have been enrolled, and the Company continues to expect to present one to two-year follow up data in the second quarter of 2023. In the European Phase Ib/II study, the six-patient lower-dose cohort is fully enrolled and the Company continues to expect to present one-year follow-up data in 2023. Four of nine patients in the European study have been enrolled in the higher-dose cohort. To date, a total of 36 patients have been enrolled across the two clinical trials including 10 control patients and 26 patients treated with AMT-130, of which 14 patients received the higher-dose and 12 patients received the lower-dose.
    

• Progress towards 2023 INDs
  
  
  • AMT-260 for the treatment of refractory temporal lobe epilepsy (rTLE) – In July 2022, the Company initiated an IND-enabling GLP toxicology study in non-human primates to support an IND submission expected in 2023.
    
    
  • AMT-191 for the treatment of Fabry disease – The Company expects to initiate a GLP toxicology study of AMT-191 in non-human primates in the second half of 2022, which is expected to support an IND submission in 2023.
    
    
• Strong cash position to advance the Company’s programs
  
  
  • As of June 30, 2022, the Company had cash and cash equivalents of $500.5 million. The Company expects that its cash and cash equivalents will fund operations into the first half of 2025 assuming the achievement of the first commercial sales milestones under the CSL Behring Agreement.
