Subjects who have had other malignancies are eligible provided that the subject is in remission and curative therapy was completed at least 5 years prior to the date informed consent, and assent when applicable, was obtained.~* A helminth parasitic infection diagnosed within 24 weeks prior to the date informed consent is obtained that has not been treated with, or has failed to respond to standard of care therapy.~* Pregnant or nursing~* If female and of child-bearing potential, positive pregnancy test or failure to adhere to acceptable method of contraception (with \<1% failure rate) during the study and for four months after the study.~* Receipt of any investigational non biologic within 30 days or 5 half-lives prior to visit 0, whichever is longer.~* A history of known immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test.~* Any other medical illness that precludes study involvement~* Positive hepatitis B surface antigen, or hepatitis C virus antibody serology, or a positive medical history for hepatitis B or C. Subjects with a history of hepatitis B vaccination without history of hepatitis B are allowed to be enrolled.~* Patients who are currently receiving or have previously received benralizumab or any other type of anti-interleukin therapy (i.e. mepolizumab, reslizumab, lebrikizumab etc.) within the last 4 months or 5 half-lives whichever is longer.~* History of anaphylaxis to any biologic therapy or vaccine.~* Receipt of immunoglobulin or blood products within 30 days prior to the date informed consent is obtained.~* Receipt of live attenuated vaccines within 30 days of starting the study drug.
