  • Patent number: 11760807
    Abstract: A method is provided for determining the efficacy of GPC3-targeting drug therapy for cancer in a patient before the start of GPC3-targeting drug therapy or for determining the continuation of GPC3-targeting drug therapy for a patient treated with GPC3-targeting therapy. The method includes determining the number of an immunocyte or an expression level of a molecule expressed on the immunocyte in a biological sample isolated from the patient before the start of GPC3-targeting drug therapy and/or the patient treated with the GPC3-targeting drug therapy, wherein when the number of the immunocyte or the expression level of the molecule expressed on the immunocyte is a predetermined value, the efficacy of the GPC3-targeting drug therapy is determined or the continuation of the GPC3-targeting drug therapy is determined. GPC3-targeting drugs and drug preparations for use according to the disclosed methods are also provided.

  • Publication number: 20230197278
    Abstract: Techniques are provided for predicting a risk of a subject experiencing a cytokine release syndrome of at least a threshold grade subsequent to receiving a treatment. The risk may be predicted based on (for example) a set of baseline characteristics, a risk-score generation model, an on-treatment cytokine level, and/or a treatment dosage. The risk may be used to generate an output corresponding to a recommendation as to whether to monitor the subject via in-patient monitoring.

  • Publication number: 20220282337
    Abstract: The present invention relates to means and methods for determining whether a patient is in need of a PD-L1 inhibitor cotherapy. A patient is determined to be in need of the PD-L1 inhibitor cotherapy if a low or absent ER expression level and an expression level of programmed death ligand 1 (PD-L1) that is increased in comparison to a control is measured in vitro in a sample from the patient. The patient is undergoing therapy comprising a modulator of the HER2/neu (ErbB2) signaling pathway (like Trastuzumab) and a chemotherapeutic agent (like dodetaxel) or such a therapy is contemplated for the patient. Also provided herein are means and methods for treating a cancer in a cancer patient for whom therapy comprising a modulator of the HER2/neu (ErbB2) signaling pathway (like Trastuzumab) and a chemotherapeutic agent (like dodetaxel) is contemplated, wherein the patient is to receive PD-L1 inhibitor cotherapy.
