Our technology is based on error-free genome editing for eradication of life-threatening persistent virus infection.
PROVIREX employs site-specific recombinase-based genome surgery technology to precisely excise chromosomally integrated viral genomes (proviruses). The major advantage of site-specific recombinases is that they function independently of host DNA repair. Therefore, in contrast to other gene editing technologies, they act with nucleotide precision producing completely error-free recombinants.
The engineered recombinase Brec1 excises HIV-1 proviruses with high specificity from the genome of infected host cells. Brec1 activity has unparalleled and lasting antiviral effects in vitro and in vivo. Consequently, plasma viral load declines to levels below the detection limits of the most sensitive assay systems. No viral rebound has been observed.
