ProQR Announces the Grant of two Key Patents, protecting QR-010 for Cystic Fibrosis in the US and EU

3 April 2017 at 7:01 AM EDT

Key Updates

  • ProQR received notice of grant for 2 key patents protecting QR-010 for CF in the US and EU until at least July 2033

  • QR-010 is currently being studied in 64 homozygous F508del patients in a Phase 1b safety, tolerability and exploratory efficacy trial. Top-line data to be reported in mid-2017

  • Top-line data from a previous clinical trial demonstrated that QR-010 restores CFTR function in homozygous F508del patients, which is an important and encouraging drug activity signal to support further development of QR-010.  A full study presentation is planned for the European Cystic Fibrosis Society Conference in June 2017. 

LEIDEN, the Netherlands, April 03, 2017 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq:PRQR) today announced the grant of two key patents protecting QR-010 in the US and EU. These patents provide the Company exclusive rights for QR-010 for the treatment of cystic fibrosis (CF) until at least July 2033.

“We are very pleased with the granting of these key pieces of intellectual property (IP) in our large and expanding IP estate, protecting QR-010 and the broader technology beyond that”, said Rene Beukema, General Counsel and Chief Corporate Development Officer of ProQR. “We pursue a very aggressive patent strategy as our 16 patent families, along with 6 in-licensed patent estates, provide multiple layers of protection for our novel products and technologies. This is an important element of our corporate strategy and we will continue to build our IP portfolio along with the development of our pipeline programs.”

US patent no. 9,605,255 is directed to methods of targeting RNA for the most common mutation in CF, called F508del, using oligonucleotides to restore the function of the CFTR protein. Last year, ProQR also received the grant of the equivalent European patent (EP 2 852 668 B1). Apart from these ProQR owned patents, ProQR has an exclusive license to US patent no. 9,617,535 from Massachusetts General Hospital covering QR-010.

About QR-010

QR-010 is a first-in-class RNA-based oligonucleotide designed to address the underlying cause of the disease by targeting the mRNA in CF patients that have the F508del mutation. The F508del mutation is a deletion of three of the coding base pairs, or nucleotides, in the CFTR gene, which results in the production of a misfolded CFTR protein that does not function normally. QR-010 is designed to bind to the defective CFTR mRNA and to restore CFTR function. QR-010 is designed to be self-administered via an optimized eFlow® Nebulizer (PARI Pharma GmbH). eFlow® is a small, handheld aerosol delivery device which nebulizes QR-010 into a mist inhaled directly into the lungs. QR-010 has been granted orphan drug designation in the United States and the European Union and fast-track status by the FDA. The QR-010 project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 633545.
