  • Patent number: 12152243
    Abstract: The invention provides non-opioid pain therapeutic compositions that include an antisense oligonucleotide (ASO) complementary to an identified target on a NaV channel mRNA. The ASO hybridizes to its target RNA and forms a duplex that recruits RNase H to degrade the RNA, thereby downregulating NaV channel synthesis, which inhibits the neuron's ability to contribute to the perception of pain. The ASO targets one of the specific identified targets, and may be provided as a gapmer that includes a central DNA segment flanked by modified RNA wings. When the composition is delivered to dorsal root ganglion (DRG) neurons in vitro, the DRG neurons exhibit a dose-dependent knockdown of NaV1.7, NaV1.8, or NaV1.9.

  • Publication number: 20230212567
    Abstract: The invention relates to therapeutic compositions for disorders associated with haploinsufficiency. The invention provides antisense oligonucleotides useful for treating early-onset epileptic encephalopathy by promoting expression of Syntaxin-binding protein 1 (STXBP1). The invention provides compositions that include synthetic antisense oligonucleotides (ASOs) that prevent certain miRNAs from interfering with production of the STXBP1 protein or bind to the 5?-UTR of the STXBP1 transcript and augment translation of the STXBP1 protein. When the composition is delivered to a patient with STXBP1 haploinsufficiency, the ASOs prevent miRNA from downregulating synthesis of STXBP1 protein.

  • Publication number: 20220403389
    Abstract: The invention provides systems and methods for discovering candidate therapies for genetic conditions and also for screening those therapies in vitro for evidence of neurotoxicity. Where a medical condition is a consequence of a genetic target such as a mutated gene, the disclosure provides in silico methods to generate lists of candidate sequences for antisense oligonucleotides (ASOs) that will potentially bind to the gene or transcripts from the gene in vivo and treat the associated condition by restoring a healthy phenotype of gene expression. The invention provides in vitro methods for screening candidate ASO sequences for symptoms of neurotoxicity in vivo. For example, candidate sequences that are output by the in silico analytical pipeline can be synthesized and assayed against live cells in vitro.

  • Publication number: 20220333105
    Abstract: Disclosed herein are antisense oligonucleotide sequences, and methods of use for treating neurological diseases. Described herein are oligonucleotide inhibitors. In various embodiments, the oligonucleotide targets a transcript for the treatment of neurological diseases, including motor neuron diseases, and/or neuropathies. For example, inhibitors of the transcript can be used to treat PD, ALS, FTD, and ALS with FTD.

  • Publication number: 20220259601
    Abstract: The invention provides compositions useful to knock down overexpression of UBE3A and treat conditions associated with Dup15q syndrome. The compositions include antisense oligonucleotides, preferably short oligonucleotides that are complementary to, and hybridize to, UBE3A transcripts in vivo. The ASOs prevent or inhibit successful translation of UBE3A mRNA into protein. Specifically, preferred embodiments include anti-UBE3A gapmersā€”oligos that include a central DNA portion flanked by RNA wings. When the gapmer hybridizes to UBE3A pre-mRNA or mRNA, the duplex hybrid recruits RNaseH, which cleaves, or digests, the UBE3A pre-mRNA or mRNA, preventing expression of the UBE3A protein. Because the ASOs prevent expression of the UBE3A protein, treatment with a composition including ASOs of the disclosure may be effective to knock down overexpression of UBE3A.
