LEIDEN, the Netherlands, Feb. 28, 2017 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq:PRQR) today announced results for the fourth quarter and full year 2016 and provided business updates.

“2017 is going to be an important year for ProQR and the 3 products under development. Our investigational product for cystic fibrosis (CF), QR-010, is scheduled to complete a phase 1b trial, and is expected to advance into a phase 2 study next year. After the recent success in our NPD biomarker study, showing clinically meaningful drug activity in homozygous F508del CF patients, we look forward to developing this product candidate with the aim of getting it to patients as quickly as possible,” said Daniel A. de Boer, Chief Executive Officer of ProQR. “QR-110, our second development program targeting Leber’s congenital amaurosis Type 10 (LCA 10), is scheduled to start a Phase 1b/2 trial in patients this year. QR-313 for dystrophic epidermolysis bullosa (DEB) is going through IND enabling work to initiate a clinical trial next year. I am excited to see that we are making good progress on our mission of bringing life changing therapies to patients in need.”

Business update and upcoming corporate milestones

  • ProQR provides an update on enrollment in the Phase 1b study of QR-010. Cohort 6 was successfully completed and cohort 7 is currently being conducted with only cohort 8 remaining to complete the study. The company plans to advance the program into a phase 2 trial in 2018. At the time of ECFS (June 7-10 2017) the company will provide a next update on enrollment in the study. The study is expected to have topline data in mid-2017.
    The Phase 1b study is designed to enroll a total of 64 homozygous adult F508del patients that have a relatively good lung function (ppFEV1 >70%). Patients receive either a single dose of QR-010 through inhalation, or 12 doses over the course of 4 weeks. 4 different dose groups are studied in this placebo controlled trial. Although exploratory efficacy outcomes are measured, the Phase 1b study is designed to evaluate safety and tolerability and identify an appropriate dose for subsequent Phase 2 and 3 studies, it is not powered to demonstrate efficacy in a statistical significant manner. Meanwhile ProQR is preparing for the start of a phase 2 program in 2018.
  • ProQR expects to start the Phase 1b/2 clinical trial with QR-110 in LCA 10 patients in H1 2017. In this trial QR-110 will be administered repeatedly through intravitreal injections. Over a year 4 doses will be given in 3 different dose groups. The trial is designed to enroll a total of 6 adult and 6 pediatric patients.

Corporate highlights 2016

  • QR-010 for F508del cystic fibrosis
    -  QR-010, ProQR’s lead molecule, demonstrated proof-of-concept activity in patients. Positive results from key biomarker clinical study were presented during the North American Cystic Fibrosis conference (NACFC) October 26 – 29, 2016 the company presented positive results from PQ-010-002, a proof-of-concept study demonstrating that QR-010 restores CFTR function in patients homozygous for F508del. CFTR is the protein channel that is defective in patients with CF, and presence or absence of function of CFTR can be measured by an important biomarker called the nasal potential difference (NPD) assay. Following 4 weeks of topical therapy, QR-010 improved the CFTR-mediated total chloride response, a direct measure of CFTR function. This was confirmed by the restoration of other indicators of CFTR function, such as the sodium channel activity. In subjects that were compound heterozygous for the F508del mutation, no meaningful difference was measured. QR-010 was observed to be safe and well-tolerated in all subjects.
    -  QR-010 demonstrated safety in single ascending dose cohorts of the Phase 1b study: During NACFC the company also announced that clinical study PQ-010-001 completed all four single-dose cohorts and blinded safety data from all cohorts was shared. PQ-010-001 is a placebo-controlled trial in subjects with CF homozygous for F508del enrolling 64 patients in a total of 8 cohorts (four single-ascending doses and four multiple-ascending doses), where QR-010 is administered through the PARI eFlow nebulizer. QR-010 was observed to be safe and well-tolerated in all single dose cohorts. The multiple dose cohorts in this study are ongoing and we are currently enrolling cohort 7. Topline safety, tolerability, pharmacokinetics and exploratory efficacy data from this study are expected in mid-2017.
    -  QR-010 granted Fast Track designation: In July 2016, QR-010 received a Fast Track designation by the US Food and Drug Administration (FDA). Drugs that are under development for serious conditions and have the potential to fulfill an unmet medical need can receive this designation. It was established with the intention to bring promising drugs to patients sooner by facilitating the development with more frequent FDA interactions and expediting the review process.
    -  QR-010 diffuses through and is stable in CF mucus: During the 12th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS) September 25 – 28, 2016 the company presented a poster that summarized some of the exciting pre-clinical work showing repeated nebulization of QR-010 did not change the diffusion speed of QR-010 in in vitro models of CF-like mucus and that QR-010 was stable in the presence of clinically relevant levels of several CF standard-of-care therapies. This is an important step towards establishing the potential delivery of QR-010 through CF mucus.
  • QR-110 for inherited blindness Leber’s congenital amaurosis Type 10
    -  QR-110, ProQR’s molecule for a rare form of congenital blindness, demonstrates important pre-clinical activity. At the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) the company presented pre-clinical data for QR-110 for LCA 10. QR-110 is a single-stranded, chemically modified RNA oligonucleotide designed to suppress the cryptic splice site created by the p.Cys998X mutation resulting in mRNA that codes for a wild-type CEP290 protein. Following intravitreal injection in vivo, QR-110 was observed to reach the outer nuclear layer of the retina, the target tissue. QR-110 was also observed to increase wild-type mRNA in cells with the p.Cys998X mutation. During the 12th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS), the company also presented a poster that showed data demonstrating that QR-110 can restore CEP290 mRNA and protein levels in primary LCA 10 compound heterozygous patient cells and homozygous optic cups in a dose dependent manner. Based on this data, and other extensive pre-clinical work, the company plans to start a first-in-human study in adult and pediatric subjects in the first half of 2017.
    -  QR-110 granted Orphan drug designation from FDA and EMA: QR-110, a first-in-class oligonucleotide therapy in development for patients with LCA 10 due to the p.Cys998X mutation received orphan drug designation (ODD) from both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). ODD in the U.S. and the European Union confers a special status for investigational drugs that are being developed for rare diseases.
  • QR-313 for dystrophic epidermolysis bullosa due to an exon 73 mutation
    -  QR-313, ProQR’s molecule for a rare disease, dystrophic epidermolysis bullosa, advances to pre-clinical development: In the second half of the year, the company advanced its product candidate for the third program, QR-313 (previously named QRX-313) into pre-clinical development for the treatment of DEB. QR-313 is an RNA oligonucleotide designed to induce the exclusion of a part of the RNA (exon skipping) that contains a disease causing mutation with the aim to restore functional C7 protein and with that the anchoring fibrils that bind the layers of skin together. QR-313 is the second program to be added to the pipeline behind the CF and LCA 10 programs from ProQR’s internal innovation (discovery) unit. The clinical program for QR-313 is expected to start in 2018.
  • ProQR’s inaugural R&D day provides key updates on drug pipeline: On March 14th the company presented at an inaugural R&D Day in New York where ProQR executives as well as external key opinion leaders presented more information on ProQR’s pipeline products including programs for CF, LCA 10, Usher syndrome, Fuchs endothelial corneal dystrophy, DEB and Alzheimer’s disease.
  • James Shannon, former CMO at GSK joins ProQR: ProQR strengthened its Supervisory Board with the appointment of James Shannon, MD in June 2016. James was the former Chief Medical Officer at GlaxoSmithKline and Global Head of Pharma Development at Novartis. James currently serves on a number of boards that include Mannkind Corp., myTomorrows and Immodulo. We believe that James’ broad knowledge and expertise in drug development and pharma will be of significant value to and further strengthens the Supervisory Board that includes several experienced biopharma executives like Dinko Valerio, founding CEO at Crucell and Henri Termeer, former CEO at Genzyme.

Financial highlights

At December 31, 2016, ProQR held cash and cash equivalents of €59.2 million, compared to €94.9 million at December 31, 2015. The decrease in cash was driven by operating expenses, partially offset by receipt of grants, change in working capital and foreign currency gains. Net cash used in operating activities during the three month period and full year ended December 31, 2016 was €7.3 million and €34.2 million respectively, compared to €6.8 million and €24.2 million for the same period last year.

Research and development costs increased to €8.1 million for the quarter ended December 31, 2016 from €6.5 million for the same period in 2015. Research and development costs for the year ended December 31, 2016 were €31.9 million, compared to €23.4 million for the same period in 2015. The increase was primarily driven by the advancement of our pipeline, which included clinical development of QR-010 for CF, preparations for the start of the first clinical trial of QR-110 for LCA 10, and pre-clinical development activities of QR-313 for DEB.

General and administrative costs increased to €2.3 million for the quarter ended December 31, 2016 from €2 million for the same period in 2015. General and administrative costs for the year ended December 31, 2016 were €9.5 million, compared to €6.8 million for the same period in 2015, which were primarily driven due to increased investments in our facilities and our support organization.

Net result for the three month period ended December 31, 2016 was a €8.8 million loss or €0.38 per share, compared to a €6.1 million loss or €0.26 per share for the same period in 2015. Net loss for the year ended December 31, 2016 was €39.1 million or €1.68 per share, compared to €20.8 million, or €0.89 per share for the same period ended December 31, 2015.

*Since 2012*

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.

About QR-110

QR-110 is a first-in-class RNA-based oligonucleotide designed to address the underlying cause of Leber’s congenital amaurosis Type 10 due to the p.Cys998X mutation in the CEP290 gene. The p.Cys998X mutation is a substitution of one nucleotide in the pre-mRNA that leads to aberrant splicing of the mRNA and non-functional CEP290 protein. QR-110 is designed to restore wild-type CEP290 mRNA leading to the production of wild-type CEP290 protein by binding to the mutated location in the pre-mRNA causing normal splicing of the pre-mRNA. QR-110 is intended to be administered through intravitreal injections in the eye and has been granted orphan drug designation in the United States and the European Union.

About QR-313

QR-313 is a first-in-class RNA-based oligonucleotide designed to address the underlying cause of dystrophic epidermolysis bullosa (DEB) due to mutations in exon 73 of the COL7A1 gene. Mutations in this exon can cause loss of functional collagen type VII (C7) protein. Absence of C7 results in the loss of anchoring fibrils that normally link the dermal and epidermal layers of the skin together. QR-313 is designed to exclude exon 73 from the mRNA (exon skipping) and produce truncated but functional C7 protein and thereby restores functionality of the anchoring fibrils.
