Experimental: Treatment (palbociclib, dexamethasone)
INDUCTION: Participants receive palbociclib PO daily and dexamethasone PO daily for 28 days in the absence of disease progression or unacceptable toxicity. Participants with disease response (M0, M1, or M2) continue to Maintenance. Patients without a disease response discontinue treatment.
MAINTENANCE: Participants receive dexamethasone with a taper PO daily on days 1-7. Participants also receive palbociclib daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Incidence of dose limiting toxicities (DLT) of the combination of palbociclib and dexamethasone [ Time Frame: Up to 28 days after discontinuation of palbociclib and dexamethasone ]Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 should be used for grading.
- Maximum tolerated dose (MTD) of the combination of palbociclib and dexamethasone defined as the highest dose level where a DLT occurs in at most one out of six patients treated [ Time Frame: Up to 28 days after discontinuation of palbociclib and dexamethasone ]CTCAE version 4.03 should be used for grading.
- Clinically relevant responses to therapy determined by bone marrow biopsy [ Time Frame: Up to 1 year ]Response rate defined as the proportion of patients who achieve an M, M1, or M2 response will be estimated along with a 95% confidence interval.
