Study Endpoints

Primary Endpoints

Intra-subject Change From Baseline of CFTR-mediated Total Chloride Transport as Measured by Nasal Potential Difference (NPD).
Baseline, at 2 and 4 weeks, and at 3 weeks post-treatment.

The primary endpoint was the within-subject change from baseline in total chloride transport as measured by NPD, after the Chloride-free+isoproterenol solution (Cl-free+iso), and was based on the average measurements of both nostrils. To provide baseline stability, baseline was defined as the average of the two most recent pre-dose values, where each pre-dose value was the average of two nostrils. A negative change from baseline of Cl-free+iso shows an improvement.

Incidence of Subjects Experiencing Treatment Emergent Adverse Events From Baseline Through End of Study
8 Days for Single-dose cohorts; 8 weeks for Multiple-dose cohorts

Number of subjects experiencing at least one treatment emergent adverse events (TEAEs)

Severity of Treatment Emergent Adverse Events From Baseline Through End of Study
8 Days for Single-dose cohorts; 8 weeks for Multiple-dose cohorts

Assessment of severity of treatment emergent adverse events (TEAEs). Severity is graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events Modified for CF (CTCAE v4.03). For events not present in this listing the following grading was applied: Mild: Asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated; Moderate: Minimal, local, or noninvasive intervention indicated; discomfort sufficient to reduce or interfere with daily activities; Severe: Medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization may be indicated; disabling; limits self-care with significant interference with daily activities; incapacitating with inability to perform self care activities of daily living; Life-threatening: Urgent intervention indicated; immediate risk of death.

Incidence of Subjects Experiencing Dose-Limiting Toxicities (DLT) in Each Dose Cohort From Baseline Through End of Study Visit.
8 Days for Single-dose cohorts; 8 weeks for Multiple-dose cohorts

DLT's were defined as an allergic reaction, acute bronchospasm or acute AEs of interest requiring (immediate) medical intervention.

Secondary Endpoints

Number of Subjects With a -6.6 mV or More Negative Change in CFTR-mediated Total Chloride Transport, and After Different Treatment Durations From Baseline Through End of Study.
2 and 4 weeks, and at 3 weeks post-treatment.
Number of Subjects With a -4 mV or More Negative Change in CFTR-mediated Total Chloride Transport, and After Different Treatment Durations From Baseline Through End of Study.
2 and 4 weeks, and at 3 weeks post-treatment.
Intra-subject Change of Sodium Transport as Measured by Nasal Potential Difference (NPD) From Baseline Through End of Study.

Frequently asked questions about QR-010

What is QR-010 used for?

QR-010 is an investigational small molecule being developed for the treatment of cystic fibrosis, specifically in patients with the ΔF508 CFTR mutation. It is designed to address the underlying genetic defect that causes the disease. QR-010 is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

Who makes QR-010?

QR-010 is being developed by ProQR Therapeutics N.V., a biopharmaceutical company traded on the NASDAQ under the ticker symbol PRQR. The company is conducting clinical trials to evaluate the safety and efficacy of QR-010 in patients with cystic fibrosis.

What phase is QR-010 in?

QR-010 is in Phase 1 clinical development. Two Phase 1 trials have been completed, with a total of 88 participants enrolled. The drug is investigational and has not received regulatory approval. ProQR Therapeutics is continuing to evaluate QR-010 for the treatment of cystic fibrosis.

What clinical trials is QR-010 in?

QR-010 has been studied in two completed Phase 1 clinical trials. The first, NCT02532764, was a dose escalation study in homozygous ΔF508 cystic fibrosis patients with 70 participants. The second, NCT02564354, was an exploratory study in subjects with the ΔF508 CFTR mutation, enrolling 18 participants.

Is QR-010 the same as other cystic fibrosis treatments?

QR-010 is a distinct investigational small molecule developed by ProQR Therapeutics for cystic fibrosis. It is designed to target the underlying cause of the disease in patients with the ΔF508 CFTR mutation. It is not the same as other approved cystic fibrosis therapies, as it is still in clinical development.
