Patents by Inventor Daniel BRAAS

Daniel BRAAS has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12630826
    Abstract: The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents, able to inhibit xanthine dehydrogenase (XDH) gene expression. Also disclosed are pharmaceutical compositions that include XDH RNAi agents and methods of use thereof. The XDH RNAi agents disclosed herein may be conjugated to targeting ligands to facilitate the delivery to cells, including to hepatocytes. Delivery of the XDH RNAi agents in vivo provides for inhibition of XDH gene expression. The RNAi agents can be used in methods of treatment of diseases, disorders, or symptoms mediated in part by XDH gene expression, such as gout and hyperuricemia.

  • Publication number: 20260009037
    Abstract: The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents, able to inhibit mitochondrial amidoxime reducing component 1 (MARC1) gene expression. Also disclosed are pharmaceutical compositions that include MARC1 RNAi agents and methods of use thereof. The MARC1 RNAi agents disclosed herein may be conjugated to targeting ligands, including ligands that comprise N-acetyl-galactosamine, to facilitate the delivery to hepatocyte cells. Delivery of the MARC1 RNAi agents in vivo provides for inhibition of MARC1 gene expression. The RNAi agents can be used in methods of treatment of diseases, disorders, or symptoms mediated in part by MARC1 gene expression, including nonalcoholic steatohepatitis (NASH), nonalcoholic fatty liver disease (NAFLD), alcoholic fatty liver disease, autoimmune hepatitis, hepatic fibrosis, cirrhosis, elevated blood cholesterol levels, hypertriglyceridemia, liver disease, and/or other MARC1-related disease.

  • Patent number: 12503696
    Abstract: The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents such as siRNAs, able to Inhibin Subunit Beta E (INHBE) gene expression. Also disclosed are pharmaceutical compositions that include INHBE RNAi agents and methods of use thereof. The INHBE RNAi agents disclosed herein may be conjugated to targeting ligands to facilitate the delivery to cells, including to hepatocytes. Delivery of the INHBE RNAi agents in vivo provides for inhibition of INHBE gene expression. The RNAi agents can be used in methods of treatment of diseases, disorders, or symptoms mediated in part by INHBE gene expression, such as obesity, diabetes, liver inflammation, dyslipidemia, or metabolic disease.

  • Publication number: 20240210423
    Abstract: The invention provides methods of diagnosing autism spectrum disorders (ASD) by identification of altered metabolic pathways in such subjects. By measuring concentrations of metabolites in a sample, such as a blood or plasma sample, from a subject, changes in the activity of specific metabolic pathways can be identified. In turn, ASD subjects can be classified based on metabolic defects. Thus, the methods allow healthcare professionals to provide patient-specific guidance on a course of treatment for individuals who have or are at risk of developing ASD.
