Patents Assigned to ProQR Therapeutics II B.V.
  • Patent number: 10941402
    Abstract: The invention relates to antisense oligonucleotides that are capable of bringing about specific editing of a target nucleotide (adenosine) in a target RNA sequence in a eukaryotic cell, wherein said oligonucleotide does not, in itself, form an intramolecular hairpin or stem-loop structure, and wherein said oligonucleotide comprises a non-complementary nucleotide in a position opposite to the nucleotide to be edited in the target RNA sequence.

  • Patent number: 10889817
    Abstract: Antisense oligonucleotides target the mutation in intron 26 of the CEP290 gene and reduce inclusion of the aberrant exon into the CEP290 mRNA. The oligonucleotides include no more than 3 consecutive guanosines, have no more than 60% guanosine nucleobases, include at most one CpG sequence, and/or do not have the potential to form a hairpin comprising 3 or more consecutive complementary base pairs.

  • Patent number: 10760076
    Abstract: The invention relates to antisense oligonucleotides (AONs) comprising repetitive trinucleotide units for use in the treatment or prevention of genetic eye diseases, preferably eye dystrophy disorders caused by RNA toxicity such as Fuch's Endothelial Corneal Dystrophy (FECD). The oligonucleotides of the present invention are used to target trinucleotide repeat (TNR) sequence expansions present in intron sequences, to prevent the disease-related sequestration of cellular proteins that interact with such TNR expansions.

  • Patent number: 10676737
    Abstract: RNA editing is achieved using oligonucleotide constructs comprising (i) a targeting portion specific for a target nucleic acid sequence to be edited and (ii) a recruiting portion capable of binding and recruiting a nucleic acid editing entity naturally present in the cell. The nucleic acid editing entity, such as ADAR, is redirected to a preselected target site by means of the targeting portion, thereby promoting editing of preselected nucleotide residues in a region of the target RNA which corresponds to the targeting portion.

  • Publication number: 20170327821
    Abstract: A method for making a change in an endogenous chromosomal DNA sequence of a mammalian cell, comprising steps of: (i) introducing into said cell an oligonucleotide having a sequence that is complementary to the chromosomal DNA sequence and that includes the change; (ii) allowing sufficient time for the cell to incorporate the change into the endogenous chromosomal DNA sequence through endogenous nucleic acid modifying pathways; and (iii) identifying the presence of the change in the chromosomal DNA sequence. The invention is particularly useful for correcting mutations in the CFTR gene.
