Experimental: Treatment (guadecitabine, atezolizumab)
Patients receive guadecitabine SC on days 1-5 and atezolizumab IV over 30-60 minutes on days 8 and 22. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
Other Names:Drug: Guadecitabine
- Incidence of dose-limiting toxicities evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (Phase I) [ Time Frame: Up to 56 days ]Descriptive summaries and analyses of CTCAE 4.0 toxicities that occur will be produced, both by patient and by cycle.
- Overall response (complete response [CR] + partial response + marrow CR + hematological improvement) (Phase II) [ Time Frame: Up to 168 days ]
- Incidence of grade 3 or higher adverse events and grade 2 toxicities that do not resolve after 3 weeks assessed by CTCAE 4.0 [ Time Frame: Up to 8 weeks ]Descriptive summaries of toxicities that occur will be produced, both by patient and by course.
- Overall response rate (Phase II) [ Time Frame: Up to 4 years ]
- Overall survival [ Time Frame: From start of treatment to death from any cause, assessed up to 4 years ]Will be analyzed using survival analysis methods.
- Percentage of patients who were transfusion-dependent on study entry who become transfusion-independent [ Time Frame: Up to 4 years ]
- Progression free survival [ Time Frame: From start of treatment to the first disease progression or recurrence, assessed up to 4 years ]Will be analyzed using survival analysis methods.
- Time to best response [ Time Frame: Up to 4 years ]Will be analyzed using survival analysis methods.
- Degree of PD-L1 expression assessed in bone marrow, T cells, and malignant cells by immunohistochemistry or flow cytometry [ Time Frame: Up to 4 years ]
- PD-1 expression by T cells and malignant cells [ Time Frame: Up to 4 years ]Relationship of PD-1/PD-L1 expression to efficacy endpoints will be explored.
- Percentage of T cells expressing PD-1/methylation levels [ Time Frame: Up to 4 years ]
- T-cell antigen recognition in MDS blood and bone marrow [ Time Frame: Up to 4 years ]Relationship of T-cell antigen recognition to efficacy endpoints will be explored.
- T-cell subset combinations in MDS blood and bone marrow [ Time Frame: Up to 4 years ]Relationship of T-cell subset combination to efficacy endpoints will be explored.
- Tumor antigen expression on MDS blasts [ Time Frame: Up to 4 years ]Relationship of tumor expression to efficacy endpoints will be explored.
