ProQR Therapeutics is a biotechnology company listed on NASDAQ with offices in Leiden, the Netherlands and Cambridge, Massachusetts, USA. ProQR is focused on the development of life changing RNA therapies to meet the unmet need of individuals and families with common and rare diseases. A team of 150+ enthusiastic ProQRians from all walks of life and more than 30 different nationalities is up to this challenge. We have the passion and commitment to make a difference in the lives of the communities we serve. Our proprietary Axiomer® RNA editing technology platform enables the editing of specific single nucleotides in RNA using the cells own editing machinery. Axiomer® RNA editing technology harnesses ADAR (Adenosine Deaminase Acting on RNA), which is machinery present in all human cells to repair G-to-A mutations, modulate protein, and enable protective mutation functions. Axiomer could potentially yield a new class of innovative medicines and treat currently untreatable diseases.
