Core B: Pharmaceutical Production

ABSTRACT - CORE B Core B is responsible for the production of clinical grade anti-human CD45 BC8 antibody (Projects 2 and 3). The antibody will be conjugated with a reagent (B10-NCS) for radiolabeling with astatine-211. All antibodies and clinical grade reagents will be produced, purified and vialed in the Biologics Production Facility of the Fred Hutchinson Cancer Research Center. Pre-clinical and clinical radiolabeling reactions will be conducted in appropriate radiochemistry laboratories at the University of Washington. Clinical grade BC8-B10 will be produced under current good manufacturing practice (cGMP) conditions and a Drug Master File will be developed and submitted to the Food and Drug Administration. In addition, Core B will be responsible for the establishment of an IND to support conduct of Phase I human clinical trials. Core B will also be responsible for radiolabeling anti-canine ICOS with 123I and 211At which are required for biodistribution and therapy studies respectively for Project 1. The anti-ICOS antibody itself will be produced using resources supplied to Project 1.
