Patent number: 11051871Abstract: Nanosecond pulsed electric field (nsPEF) treatments of a tumor are adjusted based on a size and type of the tumor to stimulate an immune response against the tumor and other tumors in the subject. Calreticulin expression on tumor cells can be detected to confirm treatment. An immune response biomarker can be measured, and further nsPEF treatments can be performed if needed to stimulate or further stimulate the immune response. Cancers that have metastasized may be treated by directly treating a tumor that is most accessible. The treatment can be combined with CD47-blocking antibodies, doxorubicin, CTLA-4-blocking antibodies, and/or PD-1-blocking antibodies. Electrical characteristics of nsPEF treatments can be based on the size, type, and/or strength of tumors and/or a quantity of tumors in the subject.Type: GrantFiled: June 23, 2020Date of Patent: July 6, 2021Assignee: Pulse Biosciences, Inc.Inventors: Richard Lee Nuccitelli, Pamela S.

Patent number: 10137152Abstract: A subject is inoculated from a disease by exposing a biopsy of a tumor or other abnormal growth to a nanosecond pulsed electric field (nsPEF). A sufficient treatment can be confirmed by detecting calreticulin on the tumor cell membranes, which indicates apoptosis occurring in the tumor cells. Treated tumor cells from the biopsy are then reintroduced into the subject. The calreticulin-exhibiting tumor cells activate the subject's immune system against the tumor, and any other like tumors in the body, and effectively vaccinates the subject against the disease. The treatment can be combined with CD47-blocking antibodies, doxorubicin, CTLA-4-blocking antibodies, and/or PD-1-blocking antibodies. The immune response may be measured at a later time. Specific electrical characteristics of the nsPEF treatments can be based on the type and/or strength of the tumor.Type: GrantFiled: January 17, 2018Date of Patent: November 27, 2018Assignee: Pulse Biosciences, Inc.Inventors: Richard Lee Nuccitelli, Pamela S.
