Abstract: Described are expression cassettes encoding CD3-half-BiTE, CXCL9 and CTLA-4 scFv. The described expression cassettes can be used to treat cancer in a subject. Methods of delivering the expression cassettes to a tumor by direct intratumoral injection and electroporation are also described.

Abstract: This invention concerns treating apparently normal tissue surrounding sites of cancerous tumors so as to reduce both the probability of a recurrence of cancer at and near the site of a cancerous tissue, and to reduce the amount of apparently healthy tissue that is usually excised along with the tumor, thereby providing a substantial benefit to the cancer patient by eliminating or delaying tumor recurrence and sparing normal tissue for its functionality and for avoiding unnecessary disfigurement.
Abstract: Example systems, apparatuses, methods, and computer program products are disclosed for electroporating cells in a tissue using a set of voltage pulses generated by capacitor charge circuitry based on a voltage supply. An example method includes continuously monitoring a set of characteristics of the voltage supply and the set of voltage pulses; generating a first set of monitor signals based on the set of characteristics; detecting a first fault condition based on the first set of monitor signals; and generating a first crowbar trigger activation signal. The example computer method further includes: detecting a second fault condition based on a second set of monitor signals generated based on the first set of monitor signals; and generating a second crowbar trigger activation signal. Subsequently, the example computer method includes electrically disconnecting the capacitor charge circuitry from electroporation electrode circuitry based on either the first or second crowbar trigger activation signal.
