  • Publication number: 20260061057
    Abstract: The present invention relates to a method comprising the steps of provision of a sample derived from a blood sample of a subject that has received a checkpoint-inhibitor therapy and is suspected of developing or has developed symptoms of immune-related adverse events (irAE), adding a photosensitizing agent to the sample, and subjecting the sample to irradiation, which preferably generates immunoregulatory NK cells in said sample. In embodiments, the photosensitizing agent is 8-methoxypsoralen and/or the irradiation is UVA irradiation. In another aspect, the invention relates to immunoregulatory NK cells obtained from a method comprising the steps of provision of a sample derived from an isolated blood sample of a subject, adding a photosensitizing agent to the sample, and subjecting the sample to irradiation. Furthermore, the invention encompasses immunoregulatory NK cells for use in the treatment and/or prevention of irAE in a subject that has received a checkpoint-inhibitor therapy.

  • Patent number: 12234480
    Abstract: In one aspect, a method of treating a subject having or at risk of having graft-versus-host disease (GvHD) generally includes administering to the subject a plurality of myeloid-derived suppressor cells (MDSCs) effective to ameliorate at least one symptom or clinical sign of graft-versus-host disease compared to a suitable control subject. In another aspect, a method of treating a tumor in a subject generally includes administering to the subject an anti-tumor therapy and co-administering to the subject an inflammasome inciting agent in an amount effective to increase inflammasome activation of MDSCs sufficiently to reduce suppressor function of the MDSCs.

  • Publication number: 20240307497
    Abstract: The disclosure relates to a substance adiponectin and/or adiponectin receptor agonist (ARA) for use in the treatment of immune checkpoint blockade (ICB)-induced immune related adverse events (irAEs) in a subject, wherein the subject is preferably receiving checkpoint blockade therapy as a cancer therapy. As well as to a combination medication comprising adiponectin and/or adiponectin receptor agonist (ARA) and a photosensitizing agent for combined use in the treatment of immune checkpoint blockade (ICB)-induced immune related adverse events (irAEs) in a subject, wherein the treatment further comprises the extracorporeal irradiation of a blood sample of the subject with ultraviolet A (UVA), preferably extracorporeal photopheresis (ECP) therapy.

  • Publication number: 20230338374
    Abstract: The invention relates to a mouse double minute 2 (MDM2) inhibitor for use in the treatment and/or prevention of a hematologic neoplasm relapse after hematopoietic cell transplantation (HCT) in a patient. In embodiments, the hematologic neoplasm is a leukaemia, preferably acute myeloid leukaemia (AML). Preferably, the patient received an allogeneic T cell transplantation, either together with the HCT and/or after HCT, such as at the time point of MDM2 administration.

  • Publication number: 20230165961
    Abstract: The present invention relates to a method comprising the steps of provision of a sample derived from a blood sample of a subject that has received a checkpoint-inhibitor therapy and is suspected of developing or has developed symptoms of an immune-related adverse event (irAE), adding 8-methoxypsoralen to the sample, and subjecting the sample to UVA irradiation. In another aspect, the invention comprises administering a treatment procedure on consecutive days, during the checkpoint-inhibitor therapy or after discontinuation of the checkpoint-inhibitor therapy.
