IMPROVED TREATMENT OF ATOPIC DERMATITIS WITH TRADIPITANT Russian patent published in 2024 - IPC A61K31/5377 A61P17/04 

FIELD: pharmaceutical industry.

SUBSTANCE: group of inventions relates to a method of administering tradipitant, and is intended for the treatment of a patient suffering from itching or atopic dermatitis. A method of administering tradipitant in an amount effective to treat a patient suffering from pruritus or atopic dermatitis includes selecting the patient for treatment based on determining that the patient's genotype includes a genotype associated with high IgE levels or a positive response to treatment with tradipitant, wherein the genotype associated with high IgE levels was selected from the group consisting of rs4575660 TT, rs276555 CC, rs74416548 ATAT, rs276556 GG, rs276560 CC, rs276561 TT, rs276562 GG, rs276563 CC, rs276564 GG, rs276571 GG, rs140796 TATTGTATTG, rs276573 TT, rs276574 GG, rs4895474 TT, rs4895475 GG, rs9483989 TT, rs9373178 CC, rs4896234 CC, rs2327798 GG, rs62420823 GG, rs17252967 CC, rs9494657 AA, rs94 02871 GG, rs9402872 CC, rs9399201 GG, rs4896235 AA, rs719640 AA, rs9373179 AA, rs9385784 TT, rs2146275 AA, rs6941440 TT, rs4896237 TT, rs6929580 GG, rs4896239 TT, rs4895479 CC, rs4895480 TT, rs4280975 GG, rs6911523 AA, rs6912319 GG, rs2280090 non-GG and rs57930837 non-AA; and the genotype associated with a positive response to tradipitant treatment is selected from the group consisting of rs 16847120 GG, rs249122 AA, rs6862796 CC, rs249137 TT, rs249138 TT, rs144713688 GAGAA, rs73258486 GG/GA, rs6480 251 CC/CT, rs6480252 TT/ TC, rs10822978 TT/TA, rs10997525 GG/GA, rs10997527 CC/CA, rs7074325 CC/CT, rs57930837 CC/CA, rs11453660 CACA/CAC, rs2199792 AA/AG, rs4963245 non-CC, rs129 90449 non-TT, rs727162 non- CC, rs58161637 non-GG, rs62622847 non-CC, rs3213755 non-AA, rs41521946 non-TT, rs28362678 non-AA, rs35624343 non-AA, rs28362677 non-TT, rs11207832 non-CC, rs1954436 non-CC, rs11207834 non-CC, rs370530530 non-CTCT, rs11207838 non-TT, rs150980554 non-AA, rs7551886 non-CC, rs6664979 non-CC, rs12043665 non-AA, rs12030784 non-TT, rs79037385 non-GG, rs74568 317 non-CC, rs3790575 non- CC and rs77939406 non-GG. A method of administering an amount of tradipitant effective to treat a patient suffering from pruritus or atopic dermatitis involves selecting the patient for such treatment based on determining that the patient's IgE level is greater than or equal to 50 kU/L.

EFFECT: use of a group of inventions makes it possible to improve the method of treating itching or atopic dermatitis in an individual in need of such treatment, due to the possibility of selecting a patient for treatment based on determining that the patient's genotype includes a genotype associated with a high level of IgE or with a positive response to treatment with tradipitant.
