LEXINGTON, Mass. and AMSTERDAM, Nov. 02, 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 third quarter of 2022 and highlighted recent progress across its business.

"We are pleased that following a comprehensive review of all available safety, biomarker and imaging data, the Data Safety Monitoring Board (DSMB) has recommended that we resume patient enrollment at the higher dose in the ongoing Phase Ib/II study evaluating AMT-130 in Huntington’s disease,” stated Matt Kapusta, chief executive officer of uniQure. "Patient safety will always be our utmost priority, and we are grateful for the close collaboration between our clinical team, study investigators and most importantly, the patients, all of whom were instrumental in completing our comprehensive investigations. We believe that AMT-130 has the potential to provide a positive impact for patients with this devastating disease for which there is no currently approved treatment. We look forward to finishing patient enrollment in the higher-dose cohort of the European study in the first half of 2023 and remain on track to announce data from the U.S. Phase I/II study in the second quarter of 2023.”

"In the third quarter, the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) completed site inspections of our Lexington, Massachusetts gene therapy manufacturing facility, and we have since received good manufacturing practice (GMP) certification from the European authorities. This is an important milestone as we seek to establish industry-leading commercial gene therapy manufacturing capabilities. Our partner, CSL Behring, continues to interact with U.S. and European health authorities as they complete their review of the marketing applications for etranacogene dezaparvovec and, assuming approval, we look forward to partnering with our colleagues at CSL Behring to bring this potentially transformational treatment option to people living with hemophilia B.”

Recent Updates

• Advancing etranacogene dezaparvovec for the treatment of hemophilia B
  
  • In May 2022, the Company’s global commercialization partner, CSL Behring, announced that the biologic license application (BLA) for etranacogene dezaparvovec (AMT-061) was accepted by the FDA for priority review. This followed the EMA validation of the marketing application authorization (MAA) in March 2022. In accordance with the Company’s commercialization and license agreement, CSL Behring is solely responsible for all regulatory activities, including any filings and agency interactions associated with etranacogene dezaparvovec and the companion diagnostic test for neutralizing antibodies to AAV5.
    
  • In the United States, the BLA remains under Priority Review with etranacogene dezaparvovec having Breakthrough Therapy Designation. 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 switch to a standard review procedure.
    
  • In July and August 2022, respectively, the EMA and the FDA conducted comprehensive, multi-day, pre-approval inspections of the Company’s Lexington manufacturing site. Following the inspection, EMA issued a GMP certificate related to the production of commercial supply of etranacogene dezaparvovec.
• Advancing AMT-130 for the treatment of Huntington’s disease
  
  • In October 2022, the DSMB reviewed all available safety, biomarker and imaging data from the ongoing Phase I/II clinical trials of AMT-130 and recommended resuming treatment at the higher dose. As previously announced in August 2022, patient enrollment at the higher dose had been voluntarily paused following the reporting of suspected unexpected significant adverse reactions (SUSARs) in three patients shortly after they received the higher dose of AMT-130. The SUSAR events in all three patients have since fully resolved.
    
    • The DSMB recommended implementing additional risk mitigation procedures during the first two weeks after the surgical administration of AMT-130, including a seven-day, in-person post-surgical visit. The DSMB also made no change to the treatment protocol regarding the use of immunosuppression that will continue to be at the discretion of the treating physician.
      
    • The Company plans to resume patient dosing in the open-label European clinical study as soon as possible and complete enrollment in the first half of 2023. To date, 10 patients have been treated in the European study, including all six patients in the lower-dose cohort and four of nine patients in the higher-dose cohort.
  • The Company still plans to announce one to two-years of follow up data from the U.S. Phase I/II clinical study in the second quarter of 2023.
    
    • All 26 patients have been enrolled in the first two cohorts of the randomized, controlled and double-blinded U.S. Phase I/II study of AMT-130, including 10 patients in the lower-dose cohort (6 treated patients and 4 control patients) and 16 patients in the higher-dose cohort (10 treated patients and 6 control patients). One control patient from the higher-dose cohort was successfully crossed over to treatment in the third quarter of 2022 and received the lower dose of AMT-130.
  • In June 2022, the Company announced 12-month follow-up data from the lower-dose cohort of the U.S. Phase I/II study of AMT-130.
    
    • 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 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.
• Progress towards 2023 Investigational New Drug (IND) Applications
  
  • 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 – In August 2022, the Company initiated a GLP toxicology study of AMT-191 in non-human primates which is expected to support an IND submission in 2023.
    
  • The Company plans to host a virtual investor event on Tuesday, November 29, 2022 to highlight the unmet medical need of patients with refractory temporal lobe epilepsy and its gene therapy candidate AMT-260, as well as advancements in platform technology and AAV manufacturing capabilities.
• Strong cash position to advance the Company’s programs
  
  • As of September 30, 2022, the Company had cash and cash equivalents of $440.3 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.
