OUTLINE: This is a phase I, dose-escalation study of guadecitabine followed by a phase IIb study. Patients are randomized to 1 of 3 cohorts.
COHORT I: Patients receive atezolizumab intravenously (IV) over 30-60 minutes on days 1 and 15. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.
COHORT II: Patients receive guadecitabine subcutaneously (SC) on days 1-5. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients also receive atezolizumab IV over 30-60 minutes on days 8 and 22. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.
COHORT III: Patients receive guadecitabine and atezolizumab as in Cohort II. Patients also receive CDX-1401 vaccine IV on day 15 and poly ICLC SC on days 15-16. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 2 months for up to 1 year.
