ProQR was born from the dream to beat cystic fibrosis in just one child. Now ProQR has one goal. Use groundbreaking science to develop medicines that will transform the lives of patients with severe genetic disorders and their loved ones.

We are ProQR

We are ProQR, a company on a mission to create new medicines for patients in need. We focus on a group of diseases called rare diseases, with a very high need for new medicines. Out of the approximately 7,000 rare diseases, less than 400 have a treatment, and we intend to change that. To treat these diseases we use RNA therapies, a technology that allows us to address inherited diseases that are caused by a genetic defect. Our focus is on diseases that are very severe or life threatening, and have limited treatment options. Amongst others we work on the development of new medicines for several forms of inherited blindness such as Leber’s congenital amaurosis and Usher syndrome, a lung disease called cystic fibrosis, and a debilitating skin disease named dystrophic epidermolysis bullosa.

Leber’s Congenital Amaurosis



Leber's congenital amaurosis Type 10 (LCA 10) is a genetic eye disorder and the leading genetic cause of childhood blindness. We are developing a potentially life changing therapy for patients that suffer from LCA 10 due to the p.Cys998X mutation in the CEP290 gene.

Cystic Fibrosis



Cystic fibrosis is a progressive disease affecting the lung and other vital organs, leading to a limited life expectancy. We are developing drugs to help patients that suffer from different forms of cystic fibrosis. Our first candidate medicine, called QR-010, for the F508del mutations showed very encouraging results in the first two clinical trials. For other forms of CF we have initiated discovery projects to find new medicine candidates.

Dystrophic Epidermolysis Bullosa



Dystrophic epidermolysis bullosa (DEB) is a severe genetic skin disease. Children with DEB are often called 'Butterfly children' as their skin is as fragile as the wings of a butterfly. We are developing several programs for different mutations causing DEB including QR-313 for approximately 2,000 patients that have DEB due to mutations in exon 73 of the COL7A1 gene.

Usher syndrome type 2



Usher syndrome is the leading cause of combined deafness and blindness. We are developing two drug candidates for different mutations causing Usher syndrome type 2 including lead program QR-421a for approximately 12,000 patients with a mutation in exon 13 of the USH2A gene and QR-411 for approximately 1,000 patients with a the c.7595-2144A>G mutation in the USH2A gene.

Axiomer® RNA editing technology



At the ProQR labs a novel technology called Axiomer® was invented that has the potential to treat a large number of diseases that are currently untreatable. Axiomer® is a novel way to correct RNA in the cells in patients and target mutations that cannot be treated with other technologies. Our scientists are working hard to make the promise of this technology for patients come true.

Spin out: Amylon Therapeutics



In September 2017 ProQR created a new company that is focused on the development of drugs for genetic brain diseases. Amylon Therapeutics is building a team of experts in brain diseases and has raised a financing round with private and institutional shareholders. ProQR retains a majority ownership stake in Amylon.
