Abstract: Described are methods and treatment schedules for treating cancer with intratumoral electroporation of an immunostimulatory cytokine combined with administration of an immune checkpoint inhibitor and a chemotherapeutic agent.

Abstract: Described are compositions comprising nucleic acids encoding CD3-half-BiTE, CXCL9, CTLA-4 scFv, and IL-12for use in treating cancer. Methods of analyzing CXCR3 expression in a tumor to identify subjects likely to respond to the compositions are also described.

Abstract: Provided herein are systems, methods, and apparatus for electroporation, which may include an applicator; an endoscope, trocar or the like; a generator; and a drug delivery device. The applicator may include a control portion, an insertion tube connected to the control portion, an actuator engaged with the control portion, and a plurality of electrodes comprising a first electrode having a first tip and a second electrode having a second tip. The plurality electrodes may be configured to move between a retracted position and a deployed position in response to actuation by the actuator. A distance between the first tip of the first electrode and the second tip of the second electrode may be greater in the deployed position than in the retracted position. Various treatment methods are also provided.
