Fig. 2From: Improved disease markers suggest dual response in a patient with metastatic castration resistant prostate cancer and chronic lymphocytic leukemia following active cellular immunotherapyPattern of IgG and IgM antibody titers following APC8015 treatment. Initial APC8015-2 (investigational form of sipuleucel-T produced using 2 μg/mL of PA2024) in December 2010 and with commercial sipuleucel-T (10 μg/mL PA2024) in December 2012. Rechallenge with commercial sipuleucel-T led to more robust IgG and IgM antibody titers.
