LEXINGTON, Mass. and AMSTERDAM, May 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 first quarter of 2022 and highlighted recent progress across its business.

“uniQure is off to a strong start in 2022, with important advancements across our key programs and earlier-stage research activities, as well as the strengthening of our executive leadership team,” stated Matt Kapusta, chief executive officer at uniQure. “In the first quarter of the year, our partner CSL Behring made important progress with global regulatory submissions for etranacogene dezaparvovec, including the granting of accelerated assessment by the EMA in Europe.”

“We also made significant advancements enrolling patients in our Phase I/II studies for AMT-130 in Huntington’s disease,” he added. “To date, we have completed 32 patient procedures across both studies and look forward to presenting in the second quarter of 2022 one-year safety and biomarker data from the 10-patient lower dose cohort of the U.S. randomized, controlled Phase I/II trial. We continue to advance our pipeline of earlier-stage gene therapy candidates and are pleased to have recently initiated a dose-ranging IND-enabling study for AMT-260 in refractory temporal lobe epilepsy. I am very proud of the uniQure team’s unwavering commitment to progressing our ambitious goals and achieving our mission of delivering the promise of gene therapies to patients.”

Recent Key Accomplishments

• Advancing the late-stage development of etranacogene dezaparvovec (AMT-061) for the treatment of hemophilia B
  • In March 2022, the Company’s global commercialization partner, CSL Behring, announced that the MAA for etranacogene dezaparvovec was validated by EMA and granted accelerated assessment. 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 either etranacogene dezaparvovec or any required AAV5 neutralizing antibody companion diagnostic.
  • In March and April 2022, the Company received $55 million in milestone payments related to CSL Behring’s submissions of marketing and license applications for etranacogene dezaparvovec.
  • In December 2021, the Company and CSL Behring announced the achievement of primary and secondary endpoints from the HOPE-B pivotal trial of etranacogene dezaparvovec in severe and moderately severe hemophilia B patients. The primary endpoint of non-inferiority in annualized bleeding rate (ABR) 18-months following administration compared to baseline Factor IX (FIX) prophylactic therapy was achieved, as was a secondary superiority endpoint on ABR.
• Advancing the clinical development of AMT-130 for the treatment of Huntington’s disease
  • In March 2022, the Company announced the completion of enrollment of all 26 patients in the first two cohorts of its randomized, double-blinded, Phase I/II clinical trial of AMT-130 for the treatment of early-stage Huntington’s disease. The ongoing Phase I/II clinical trial of AMT-130 is a randomized, sham controlled, double-blinded study to explore the safety, tolerability, and proof of concept of AMT-130 in patients with early manifest Huntington’s disease. A third cohort exploring the use of an alternative stereotactic navigation system to simplify placement of infusion catheters in up to 18 additional randomized patients is expected to commence enrollment in the second half of 2022.
  • Also in March 2022, the Company completed enrollment of the lower-dose cohort of six patients in the European Phase Ib/II study of AMT-130. The open-label study will enroll 15 patients with early manifest Huntington’s disease across the same doses being explored in the U.S study. Together with the ongoing U.S. study, the European study is intended to establish safety, proof of concept, and the optimal dose of AMT-130 to take forward into Phase III development, or into an adaptive confirmatory study should an accelerated registration pathway be feasible. In total, 59 patients are expected to be enrolled in the U.S. and European Phase I/II trials of AMT-130.

• In December 2021, initial observations were announced on the first four patients in the low-dose cohort of the double-blinded and randomized U.S. Phase I/II study of AMT-130. The investigational gene therapy was generally well tolerated with no serious adverse events related to treatment. NfL increased as expected immediately following the AMT-130 surgical procedure and returned to baseline in the two treated patients. NfL remained relatively constant in the two untreated control patients. Structural magnetic resonance imaging did not reveal any clinically meaningful safety findings in either treated or control patients at one year of follow-up.
  • During the second quarter of 2022, the Company expects to provide a clinical update on all 10 patients followed for twelve months in the lower dose cohort, including safety, mHTT and NfL biomarker data. Volumetric MRI and functional data is expected to be available during the first half of 2023, after all patients in the two dose cohorts are unblinded.

• Advancing our research pipeline into the clinic and the Company’s proprietary technologies
  • Progress towards 2023 INDs:
    • Refractory Temporal Lobe Epilepsy (rTLE) – In March 2022, the Company initiated an IND-enabling dose-ranging study of AMT-260 and plans to initiate a GLP toxicity study in non-human primates in the second half of 2022 to support an IND submission in 2023.
    • 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.
  • The Company today announced its significant scientific presence at the upcoming American Society of Gene and Cell Therapy (ASGCT) Hybrid Congress, to be held May 16-19, 2022 in Washington, DC. In total, six data presentations will be delivered by the Company’s researchers and scientists, including five posters, and one oral presentation. These presentations will highlight the Company’s research and technology capabilities and feature some new preclinical findings on the company’s gene therapy candidates for Huntington’s disease, refractory temporal lobe epilepsy, Fabry disease, Parkinson’s disease, Amyotrophic lateral sclerosis (ALS) and Alzheimer’s disease.
• Enhancements to the Leadership Team
  • In March 2022, Richard Porter was appointed Chief Business Officer, responsible for global business development, corporate strategic planning, market access and commercial planning. Dr. Porter joined the Company following the acquisition of Corlieve Therapeutics in July 2021. Dr. Porter brings over 25 years of R&D experience to the Company, having previously served as the COO of Therachon, until its acquisition by Pfizer.
