Scientists at ProQR have invented a new way to use RNA oligonucleotides to alter RNA. The Axiomer™ RNA editing technology enables the editing of specific single nucleotides in RNA using the cells own editing machinery. This technology has the potential to become a new class of medicine and treat currently untreatable diseases.

We aim to improve patients’ lives by applying our RNA editing platform technology that enables your own body to treat disease.

The first partner for the Axiomer™ technology is Eli Lilly and Company. The global licensing and research collaboration focuses on the discovery, development, and commercialization of potential new medicines for genetic disorders in the liver and nervous system. The companies will use our proprietary Axiomer™ RNA editing platform to progress up to five new drug targets toward clinical development and commercialization.

A new way to design therapies

A new way to design oligonucleotide therapies

Antisense oligonucleotides (AONs) have been used as therapeutics for the last few decades. ProQR has built an extensive pipeline of investigational RNA therapies based on the technologies already available. But our scientists have gone beyond that and invented an entirely new way of using oligonucleotides for the treatment of genetic diseases. These Editing Oligonucleotides (EONs) enable specific single nucleotide edits to RNA to reverse a mutation or change a protein to prevents or treat disease.

RNA editing with ADAR

RNA base editing with ADAR

The ADAR (Adenosine Deaminase Acting on RNA) machinery is present in all human cells where it edits A’s to I’s in RNA. This A-to-I RNA editing is a very frequently occurring natural process. Our Axiomer platform evolved from the mechanism nature has developed.

The Axiomer™ technology

The Axiomer technology

Our Axiomer EONs (Editing Oligonucleotides) can be designed to bind the mRNA at a specific site and mimics the double stranded structure that normally attracts ADAR. This way the EON can induce editing of a specific ‘A’ to an ‘I’ where it is needed for therapeutic purposes using the cell's own editing machinery. In short, the Axiomer technology enables your own body to treat disease.

Applicability & potential

Applicability & potential

The EONs are short single stranded RNA molecules that are chemically modified to provide them with ideal drug-like properties for efficacy and uptake into cells. There are over 20,000 disease-causing mutations that can be ‘reversed’ by A-to-I editing. The vast majority of these diseases are currently untreatable.

Goals and strategy

Goals and strategy

We will further develop this platform through product and business development and plan to establish clinical proof of concept as soon as possible. The platform is uniquely positioned to target a wide range of diseases in a highly specific manner.
