Title: A Pilot Study of SGI-110 in Combination With an Allogeneic Colon Cancer Cell Vaccine (GVAX) and Cyclophosphamide (CY) in Metastatic Colorectal Cancer (mCRC) as Maintenance Therapy1

Principal Investigators: Nilofer Azad, MD, The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins

Description: For this randomized, open-label, phase 1 trial, researchers are evaluating whether guadecitabine (SGI-110), a DNA methyltransferase inhibitor, is safe and effective in combination with cyclophosphamide and GVAX, a colon cancer tumor vaccine, among patients with metastatic colorectal cancer.

All patients will initially receive cyclophosphamide, GVAX, and guadecitabine; if a response is recorded, patients will be assigned to receive cyclophosphamide and GVAX or guadecitabine alone.

The primary outcome measures are the difference in CD45RO+ tumor infiltrating lymphocytes in biopsies taken before/after treatment and the number of adverse events. Secondary outcomes include overall and progression-free survival.
