SGI-110 in Combination With an Allogeneic Colon Cancer Cell Vaccine (GVAX) and Cyclophosphamide (CY) in Metastatic Colorectal Cancer (mCRC)

Phase 1
Completed
Conditions
Metastatic Colorectal Cancer
Interventions
Biological: GVAX
Registration Number
NCT01966289
Lead Sponsor
Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins
Brief Summary

This study will be looking at whether CY/GVAX in combination with SGI-110 is effective (recruits CD45RO+ T cells to the tumor which may be a marker of anti-tumor activity) and safe in patients with metastatic colon or rectum cancers.

Cohort 1:CY/GVAX concurrently with SGI-110CYDuring each of the four cycles, Cyclophosphamide (CY) is administered on Day 1 at 200 mg/m2, the colon cancer tumor vaccine (GVAX) is administered on Day 2 at 5E8 colon cancer cells + 5E7 Granulocyte macrophage-colony stimulating factor (GM-CSF) secreting cells, and SGI-110 is administered on Days 1-5 at 60 mg/m2. Each cycle is 28 days. Enrollment will begin first in Cohort 1 and 2. If a response to the treatment is seen in Cohorts 1 and 2, enrollment in Cohort 3 and 4 will begin.
