  • Publication number: 20250059610
    Abstract: The disclosure provides a method for treating a subject afflicted with a tumor, e.g., lung cancer, having a high tumor mutation burden (TMB) status comprising administering to the subject an immunotherapy, e.g., an anti-PD-I antibody or antigen-binding portion thereof. The present disclosure also provides a method for identifying a subject suitable for an immunotherapy, e.g., a treatment with an anti-PD-I antibody or antigen-binding portion thereof, 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-I 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: 20250050082
    Abstract: A delivery assembly for an ingestible device for delivering a fluid preparation into a GI lumen wall or surrounding tissue of a subject includes a housing, a piston-needle assembly, a membrane, and a valve member. The housing defines a chamber. The piston-needle assembly is movably disposed in the chamber and includes an inlet and a channel. The membrane is coupled to the housing such that the membrane and the housing cooperatively define a reservoir for containing the fluid preparation. The housing further defines an opening extending between the chamber and the reservoir. In response to sufficient movement of the piston-needle assembly relative to the housing, the valve member opens to allow the fluid preparation to flow from the reservoir through the opening into the chamber where the fluid preparation is directed to the inlet and the channel for delivery into the GI lumen wall or surrounding tissue thereof.
