- In the same multiple dose groups a supportive trend of improved lung function was observed up to 4.0% mean absolute change in ppFEV1compared to placebo. In a pre-defined subgroup of subjects with a lower lung function at baseline a mean absolute change in ppFEV1 was observed up to 10.9% compared to placebo.
- After inhaled administration in some dose groups, QR-010 was detected in the blood.
- ProQR and the Cystic Fibrosis Foundation Therapeutics intend to expand their partnership to explore the inhaled oligonucleotide platform to target stop-codon mutations in CF.
- Management will discuss the top-line results during a conference call today at 5 pm ET.
LEIDEN, the Netherlands, Sept. 25, 2017 (GLOBE NEWSWIRE) -- ProQR Therapeutics N.V. (Nasdaq:PRQR) today announced positive preliminary top-line results from a Phase 1b safety and tolerability clinical trial (Study PQ-010-001; NCT02532764) of QR-010, a novel investigational RNA therapeutic in subjects with cystic fibrosis (CF). Full data from the trial will be presented at the North American CF Conference (NACFC) on November 2-4, 2017.
Study PQ-010-001 was a Phase 1b, randomized, double-blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability and pharmacokinetics of QR-010 in adult subjects with CF homozygous for the F508del mutation. This trial studied 4 dose levels of QR-010 administered via inhalation in 4 single-dose and 4 multiple-dose groups. A number of exploratory efficacy endpoints were assessed in the multiple dose groups: respiratory symptoms (as measured by a validated patient-reported outcome tool, the Cystic Fibrosis Questionnaire-Revised Respiratory Symptom Score, or CFQ-R RSS), lung function (as measured by mean absolute change in percent predicted forced expiratory volume in 1 second, or ppFEV1), sweat chloride test and weight change. This study included subjects with, on average, a normal lung function at baseline (mean ppFEV1 86%, range 69-116%). As therapeutic trials typically study subjects with normal-to-severe lung function at baseline (ppFEV1 <90%), a subgroup was pre-defined to analyze the exploratory efficacy endpoints in this population. The trial recruited 70 participants and was conducted at 23 sites in 10 countries in Europe and North America.
J. Stuart Elborn, the principal investigator of the study, Clinical Chair in Respiratory Medicine at Imperial College, Consultant at Royal Brompton Hospital, and immediate past-president of the European Cystic Fibrosis Society, added, "QR-010 exceeded expectations in this study as an innovative investigational therapy for the treatment of cystic fibrosis for which the need remains high. The improvements demonstrated in reduction of respiratory symptoms are very encouraging and intriguing and of course of enormous importance to people with CF. The results of this study together with the previous proof of concept study are strongly supportive of the further development of QR-010."
In this trial QR-010 was observed to be safe and well-tolerated across all doses, with an overall safety profile similar to placebo. There were no serious adverse events related to treatment. After inhaled administration in some dose groups, QR-010 was detected in the blood. Subjects who received QR-010 in the 6.25, 12.5 and 25 mg multiple dose groups reported fewer respiratory symptoms after 4 weeks of treatment as measured by the increased CFQ-R RSS, with mean improvements of 13.0, 19.2 and 14.3 points, respectively, compared to placebo. The effect was more pronounced in the pre-defined subgroup of subjects with a lower lung function at the start of the study (baseline ppFEV1 70-90%) with a mean increase of up to 27.5 points compared to placebo. These improvements exceeded the minimal clinically important difference (MCID) of 4.0 points. A supportive trend of improved lung function was observed in the same multiple dose groups, as measured by mean absolute change in ppFEV1 compared to placebo. The trend was stronger in the subgroup of subjects with a lower lung function at baseline. The table below summarizes the data per multiple dose group. As expected, no effect was observed on sweat chloride and weight.

The Phase 1b study achieved its goals for evaluation of QR-010 including demonstrating safety and tolerability across a range of doses, identified a dosing window, exhibited uptake of the RNA oligonucleotide into circulation following inhalation, and demonstrated early signals of clinical efficacy.
"The positive results in the first two clinical trials of QR-010 significantly increase the confidence that QR-010 has the potential to become an effective treatment of CF. The improvement in CFQ-R RSS with the supportive FEV1 data as shown in this Phase 1b trial is very exciting," said Noreen R. Henig, M.D, Chief Medical Officer at ProQR. "I want to thank the entire CF community including those living with CF, clinical investigators, scientists, the CF Foundation, the European CF Society and the US and European therapeutic development networks for their unwavering commitment."
Partnership with Cystic Fibrosis Foundation Therapeutics (CFFT)
ProQR and CFFT entered into a partnership in 2014 to develop QR-010 for people with CF due to the F508del mutation. The initial partnership included support for the Phase 1b trial as well as the NPD proof of concept study that reported positive results in 2016. Based on the results of the clinical trials of QR-010, ProQR and CFFT intend to expand the partnership to explore the inhaled oligonucleotide platform for stop-codon mutations (also called "Class I" mutations) in CFTR. Stop-codon mutations cannot be targeted with small molecule potentiator or corrector molecules, and therefore have a high unmet medical need. ProQR intends to target these mutations using its proprietary Axiomer® technology, which has shown compelling data in non-clinical studies, to repair the stop-codon mutations in the RNA, leading to removal of the premature stop-codon. Approximately 12,000 patients, accounting for 15% of CF patients in the western world, have a stop-codon mutation leading to a severe form of CF.
"The results of this Phase 1b trial support QR-010's potential to be a meaningful therapy for people with cystic fibrosis," said Daniel A. de Boer, Chief Executive Officer at ProQR. "With these results in hand we are designing a path forward for the development of QR-010, either independently or with a potential partner. Furthermore we are looking forward to expanding our partnership with the CFFT to explore the inhaled oligonucleotide platform also for people that have CF due to stop-codon mutations."
About the PQ-010-001 Trial
The Phase 1b study was a trial designed to assess safety, tolerability and pharmacokinetics of QR-010. A number of exploratory efficacy endpoints were assessed in the multiple dose groups. A total of 4 dose levels were studied: 6.25, 12.5, 25 and 50 mg of QR-010 in solution per dose administered via inhalation using the PARI eFlow® nebulizer. Subjects eligible to participate were males and females of 18 years and over with a ppFEV1 of greater than or equal to 70% at time of inclusion, homozygous for the F508del mutation, and not taking CFTR modulator drugs. The study design planned to enroll 8 cohorts of 8 subjects (6 receiving QR-010, 2 receiving placebo). In cohorts 1-4, a single dose of QR-010 was administered, and in cohorts 5-8 twelve doses of QR-010 were administered over a 4-week period.

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 technology was exclusively licensed from Massachusetts General Hospital. The F508del mutation results in the production of a misfolded CFTR protein that does not function normally. QR-010 is a single agent 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 received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 633545.
About Cystic Fibrosis
Cystic fibrosis (CF) is the most common fatal inherited disease in the Western world and affects over 75,000 patients worldwide. In people with CF, a defective CFTR gene causes a thick buildup of mucus in the lungs, pancreas and other organs. In the lungs, the mucus clogs the airways and traps bacteria leading to infections, extensive lung damage and eventually, respiratory failure. There is no cure for CF. Disease manifestations lead to a shortened life expectancy with a median age of death of 30 years. Although over 1,900 CF-causing gene mutations have been identified, approximately 85% of all CF patients are affected by the F508del mutation. Among all CF patients, approximately 50% are homozygous for the F508del mutation.
ProQR Therapeutics is dedicated to changing lives through the creation of transformative RNA medicines for the treatment of severe genetic rare diseases such as cystic fibrosis, Leber's congenital amaurosis 10 and dystrophic epidermolysis bullosa. Based on our unique proprietary RNA repair platform technologies we are growing our pipeline with patients and loved ones in mind.
