Generation of antibodies to tumor antigens and generation of tumor specific complement dependent cytotoxicity by administration of oncolytic vaccinia virus
First Claim
1. A pharmaceutical composition comprising a therapeutically effective amount of polyclonal complement dependent cytotoxic (CDC)-response producing antibodies specific to multiple tumor cell antigens in an animal and a pharmaceutically acceptable carrier and/or diluent, wherein said composition is produced by a method comprising (a) administering to an animal having a tumor an amount of a composition comprising a replication competent oncolytic vaccinia virus effective to induce polyclonal antibodies in said animal that mediate a CDC response specific to said tumor cell antigens and thereafter (b) obtaining a blood or serum sample from the animal containing said CDC-response producing antibodies and/or B cells producing said antibodies (c) confirming the presence of said antibodies and/or B cells producing said antibodies in said blood or serum sample and (d) isolating CDC-response producing antibodies from said blood or serum, expanding said CDC-response producing antibodies ex vivo or producing CDC-response producing antibodies from said B cells and formulating into a composition, wherein the composition comprises polyclonal antibodies that recognize multiple tumor cell antigens selected from the group consisting of RecQ protein-like (DNA helicase Q1-like) (RECQL);
- leptin receptor (LEPR);
ERBB receptor feedback inhibitor 1 (ERRFI1);
lysosomal protein transmembrane 4 alpha (LAPTM4A); and
RAB1B, RAS oncogene family (RAB1B).

Abstract
The present invention relates to methods and compositions for use in inducing tumor-specific antibody mediated complement-dependent cytotoxic response in an animal having a tumor comprising administering to said animal a composition comprising a replication competent oncolytic virus wherein administration of the composition induces in the animal production of antibodies that mediate a CDC response specific to said tumor.
