PD-1 Inhibition in Advanced Myeloproliferative Neoplasms

Detailed Summary

The purpose of this study is to test the effectiveness of a drug called pembrolizumab in patients with Myeloproliferative Neoplasm (MPN); chronic phase (MF-CP), accelerated phase (MPN-AP), or blast phase (MF-BP). Myelofibrosis neoplasm (MPN) is a group of diseases of the bone marrow in which excessive cells are produced. Pembrolizumab also known as Keytruda is a drug that has recently been approved in the United Stated by the Food and Drug Administration (FDA) for the treatment of patients with unresectable or metastatic melanoma and disease progression. Pembrolizumab is experimental in the treatment of MPN. The researchers want to find out what effects, good and /or bad it has on participants and the disease. Participants qualify to take part in this research study if have been diagnosed with a MPN blood disorder called myelofibrosis (MF). Accelerated (10-19% blasts in the blood or bone marrow) and blast phase (\>20% blasts in the blood or bone marrow) MPN has been a difficult disease to treat. The term "blasts" refers to immature cells found in the bone marrow. They are not fully developed, and therefore, do not yet carry out any particular function within the body. Funds for conducting this research are provided by Merck and Company, the manufacturer of the study drug pembrolizumab.
