“The Leukemia & Lymphoma Society (LLS) is partnered with the MPN Research Foundation (MPNRF) to support a grant program whose objective is to change the trajectory and ultimate prognosis for patients with myeloproliferative neoplasms, particularly myelofibrosis, polycythemia vera and essential thrombocythemia. The MPN Challenge program represents an important partnership between LLS and MPNRF, who share a mission to advance the scientific understanding of MPNs and bring new treatments and the hope for a cure to patients with these rare diseases. We anticipate opening the next MPN Challenge grant program in early 2016,” state the LLS.
