  • Publication number: 20250382368
    Abstract: This disclosure provides a method for treating a subject afflicted with tumor, which method comprises administering to the subject an antibody or an antigen-binding portion thereof that specifically binds to a Programmed Death-1 (PD-1) receptor and inhibits PD-1 activity. In some embodiments, the tumor is derived from a non-small cell lung cancer (NSCLC). In some embodiments, the tumor expresses Programmed Death Ligand 1 (PD-L1), Serine/Threonine Kinase 11 (STK11), or both PD-L1 and STK11.

  • Patent number: 12466888
    Abstract: The disclosure provides a method for treating a subject afflicted with a tumor derived from a small cell lung cancer (SCLC) having a high tumor mutational burden (TMB) status comprising administering to the subject a monotherapy comprising an anti-PD-1 antibody or a combination therapy comprising an anti-PD-1 antibody and an anti-CTLA-4 antibody. The present disclosure also provides a method for identifying a subject suitable for treatment with an anti-PD-1 antibody or a combination therapy comprising an anti-PD-1 antibody and an anti-CTLA-4 antibody comprising measuring a TMB status of a biological sample of the subject. A high TMB status identifies the patient as suitable for treatment with an anti-PD-1 antibody or antigen-binding portion thereof. The TMB status can be determined by sequencing nucleic acids in the tumor and identifying a genomic alteration, e.g., a somatic nonsynonymous mutation, in the sequenced nucleic acids.

  • Publication number: 20250340645
    Abstract: The disclosure provides a method for treating a subject afflicted with a tumor comprising administering to the subject a therapeutically effective amount of an anti-PD-1 antibody or antigen-binding portion thereof or an anti-PD-L1 antibody or anti-gen-binding portion thereof, wherein the subject is identified as having a high inflammatory gene signature score. In some embodiments, the high inflammatory gene signature score is determined by measuring the expression of a panel of inflammatory genes in a tumor sample obtained from the subject, wherein the inflammatory gene panel comprises CD274 (PD-LI), CD8A, LAG3, and STAT1.
