Vasisht TADIGOTLA 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: 11891664
    Abstract: The invention relates generally to the use of microvesicle biomarkers such as nucleic acids, including nucleic acid signatures, and/or proteins for assessing a kidney transplant rejection in a patient. The invention further relates to assessing, and/or to monitoring kidney transplant rejection in patients who have received a renal transplant.
    Type: Grant
    Filed: May 16, 2018
    Date of Patent: February 6, 2024
    Assignees: Exosome Diagnostics, Inc., The Brigham and Women's Hospital
    Inventors: James Hurley, Christine Coticchia, Robert Kitchen, Vasisht Tadigotla, Johan Karl Olov Skog, Jamil Azzi
  • Publication number: 20240021272
    Abstract: Systems and method for determining variants can receive mapped reads, and call variants. In embodiments, flow space information for the reads can be aligned to a flow space representation of a corresponding portion of the reference. Reads spanning a position with a potential variant can be grouped and a score can be calculated for the variant. Based on the scores, a list of probable variants can be provided. In various embodiments, low frequency variants can be identified where multiple potential variants are present at a position.

  • Patent number: 11427864
    Abstract: The present invention relates generally to methods and kits for detecting one or more biomarkers, such as an Epidermal Growth Factor Receptor (EGFR) mutation, e.g., T790M mutation, L858R mutation, one or more exon19 insertions and/or one or more exon19 deletions in the EGFR gene, in a biological sample to aid in diagnosis, prognosis, monitoring, or therapy selection for a disease such as, for example, cancer. The methods and kits are useful in aiding in diagnosis, prognosis, monitoring, or therapy selection for lung cancer, e.g., non-small cell lung cancer (NSCLC).

  • Patent number: 11396676
    Abstract: The invention provides a series of steps that prepare nucleic acids (RNA and/or DNA) isolated from extracellular vesicles for sequencing. This enables a wide diversity of RNAs and/or DNAs, to be efficiently detected. These can then be used to identify various attributes such as gene expression, alternative splicing, and the detection of both somatic and germline mutations including single nucleotide variants (SNV) and structural variations (insertions/deletions, fusions, inversions).

  • Patent number: 11345957
    Abstract: The present disclosure relates to methods for treating glioblastoma in a subject in need thereof using gene signatures in exosomal RNA derived from the subject. The gene signatures comprise: at least one of FAM229B, ZNF35, CTD-2647L4.4, CABP5, CYP20A1, CEP126, DTX2P1-UPK3BP1-PMS2P11, RP11-507K12.1, KRBA2, CALD1, LRFN1, RP2, SLC2A13, CDKL3, SLC8A3, ANTXR2, TIGD5, AC074289.1 RP11-932O9.7; at least one of tRNA-Lys-CTT-2-2, tRNA-Pro-AGG-2-7, LAMTOR2, RAD51AP1, DENND2A, A1BG, THSD1, CSF1, RP11-332M2.1, ZNF717, ZNF860, ORC6, Clorf50, PSPH, HIST1H4C, CYP2U1, THAP8, TMEM192, NAA20; or at least one of CREBBP, CXCR2 and S100A9. The treatment methods comprise measuring the expression level of at least one of the aforementioned genes in exosomal RNA from a subject and administering to the subject a glioblastoma treatment based on the expression level(s).
