Taking gene therapy to the next level

Genome editing-based therapies become more ambitious and real with a promising statement to a large spectrum of genetic diseases.

Since the first report in the early 90’s of a 4 years old child receiving a substitute gene coding for the adenosine deaminase (ADA) to treat his severe immune system deficiency [1], gene therapy rapidly evolved over the last decades with multiple treatments approved by the U.S Food and Drug Administration.

A new era for genome editing and biotechnologies

 

Indeed, the 2020 Nobel Prize technology CRISPR-Cas9 is a revolution for genome editing and opened news paths for gene therapy.

This methodology generated an incredible upheaval for developing new treatment approaches as well as a very useful tool for innovative therapeutic preparations such as CAR-T cells [2-4] and the U.S Food and Drug Administration approved successful clinical trials with the CRISPR genome editing technique especially for rare blood diseases.

Nevertheless, even if CRISPR brings a lot of hope and a new manner of treating genetic diseases, the large-scale use of this technology is still hampered by technical issues such as efficiency, specificity [5] and it is restrained by the size of the DNA recombination to perform [6].

Life is and will ever remain an equation incapable of solution, but it contains certain known factors.

Our technology is not based on existing genetic tools

 

The GREAT technology from QUIDDITAS Therapeutics was created to fill this gap and bring gene therapy to the next level.

GREAT is able to cut any single or double stranded nucleic acid sequences (RNA or DNA) and paste any length of nucleic acids anywhere in the genome in a fully controlled manner.

Thus, this tool can permit to replace a full gene or exon by cutting out a selected sequence and adding another full double stranded sequence.

Our technology is not only multifunction, but also permits to bypass actual technical limitations, thus permitting an absolute gene recombination.
