Myeloproliferative Neoplasm
Conditions
Brief summary
The purpose of this research study is to look at how safe and useful a drug called azacitidine in combination with a drug called venetoclax, is in people with accelerated or blast phase BRC-ABL negative myeloproliferative neoplasms.
Detailed description
All participants in this study will receive azacitidine and venetoclax. This study will be done in multiple stages: Safety Run-In Period - 7 participants will receive the study drugs to ensure that the combination is safe and tolerable. Stage 1 - About 15 participants will receive the study drugs and will be evaluated to see whether they respond to the study drugs. Stage 2 - If enough participants in Stage 1 respond to the study drugs, then Stage 2 will begin. During this stage, an additional 25 participants will take part in the study to further see if participants respond to the study drugs.
Interventions
Azacitidine is a hypomethylating agent that works by activating certain genes in the body to help cells mature and to kill abnormal bone marrow cells.
Venetoclax is a drug that blocks a protein called B-cell lymphoma (BCL2) protein from working. BCL2 is a protein that helps control whether a cell lives or dies and is thought to help cancer cells to live. Blocking BCL2 is believed to help kill cancer cells.
