9L-13-1: Correlative Biomarker Study for MPD-RC Treatment Studies in the Philadelphia Chromosome Negative Myeloproliferative Neoplasms (MPN)


The Philadelphia chromosome negative myeloproliferative neoplasms (MPN) polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) are clonal hematopoietic malignancies originating at the level of the pluripotent hematopoietic stem cell. MPNs have the potential to undergo clonal evolution and a stepwise progression that terminates in bone marrow failure due to myelofibrosis, ineffective hematopoiesis, or in transformation to acute leukemia. Recently it has been learned that a point mutation in the tyrosine kinase, Jak2, accounts for the characteristic growth factor hypersensitivity observed in MPNs, however, the molecular mechanisms that result in the etiology and progression of these neoplasms have not been fully characterized. Because of the long evolution of these neoplasms, identifying biomarkers of disease progression and the development of molecularly targeted translational therapies has been difficult.The principal objective of this study is to collect and store tissue samples from patients with myeloproliferative neoplasms (PV, PMF, and ET). Tissue samples will be used to perform a variety of biomarker studies to monitor the effects of a particular therapeutic intervention. The specimens will be obtained from study participants either at the time of diagnosis, remission, or at relapse, or other specific time points as specified by the individual treatment/research protocols.Study participants qualify to take part in this research study because they have agreed to participate in an MPD-RC treatment study for which this biomarker study is a mandatory component. Participants will be asked to participate in this study that allows for the storage of a small portion of the participants blood and bone marrow and toenail clippings for research. This study is being conducted by the Myeloproliferative Disorders Research Consortium (MPD-RC) through a grant provided by the National Cancer Institute (NCI). These samples will be frozen and securely stored at the MPD-RC Research Laboratory at the New York Blood Center in New York, New York. Participation in this study is expected to last from 2 to 4 years.
