PPHM SAB’er Dr. Rolf Brekken (UTSW) is speaking at a CRI “Cancer Immunotherapy” webinar on 5-28-14 (2-2:45pmET). His speech is titled, “Reactivating Your Immune System to Fight Cancer.” This is 2 days before ASCO begins this year (May30-June3 2014). Dr. Brekken’s is the first webinar in a series of 5, kicking off June as “Cancer Imunotherapy Month”. The link to this is on Peregrine’s homepage: http://www.peregrineinc.com

FULL ABSTRACT:
BACKGROUND: Escape from immune surveillance is a frequent mechanism of tumor initiation, proliferation, and resistance to treatment. Bavituximab is a chimeric monoclonal antibody with immune modulating properties. Bavituximab targets exposed phosphatidylserine (PS) on tumor vascular endothelium, tumor cells and tumor derived exosomes. Exposed PS in the tumor microenvironment suppresses immune and inflammatory responses by binding to PS receptors on myeloid derived suppressor cells (MDSC) and M2 macrophages, which leads to production of anti-inflammatory cytokines such as TGF-B and IL-10 which inhibits the development of an adaptive immune response. In preclinical models, PS-targeting antibodies counter these effects, resulting in production of pro-inflammatory cytokines such as TNF-a and IL-1B, maturation of dendritic cells and induction of tumor specific cytotoxic T lymphocyte immunity. Administration of docetaxel increases PS exposure within the tumor microenvironment and also suppresses MDSCs, thereby enhancing bavituximab's effects. In a double-blind Phase II clinical trial, bavituximab 3 mg/kg plus docetaxel was well-tolerated and demonstrated 60% improvement (11.7 vs 7.3 month) in median overall survival (OS) compared to control.
METHODS: In this randomized, double-blind, global Phase III clinical trial, approximately 600 pts with 2nd-line stage IIIb/IV non-squamous NSCLC will be randomized 1:1 to receive up to six 21-day cycles of docetaxel 75 mg/m2 with placebo or bavituximab 3 mg/kg weekly until disease progression or unacceptable toxicity. Patients must have one progression on platinum doublet therapy for advanced disease. Prior maintenance or targeted therapy is allowed if only 1 progression occurred. Within each geographic region, patients will be stratified by disease stage and prior maintenance/targeted therapy. The primary endpoint is overall survival and secondary endpoints include overall response rate (modified RECIST 1.1), progression free survival (PFS) and safety.
