The primary purpose of this study is to measure the response rate in participants with the myeloproliferative neoplasms (MPNs), polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF) when treated with LY2784544, including those who have demonstrated an intolerance to, failure of primary response to, or have demonstrated disease progression while on ruxolitinib.

Inclusion Criteria: - Have a diagnosis of polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF) as defined by the World Health Organization (WHO) diagnostic criteria for myeloproliferative neoplasms (Swerdlow et al. 2008) and meet the following additional subtype specific criteria: - PV: have failed or is intolerant of standard therapies or refuses to take standard medications - ET: have failed or is intolerant of standard therapies or refuses to take standard medications - MF (participants with MF must meet at least 1 of the following): have intermediate 1, intermediate 2, or high-risk MF according to the Dynamic International Prognostic Scoring System (DIPPS Plus) for Primary Myelofibrosis (Gangat et al. 2011); or have symptomatic MF with spleen greater than 10 centimeter (cm) below left costal margin; or have post-polycythemic MF; or have post-ET MF - All PV, ET, and MF participants must meet the following criteria: o Have a quantifiable level of janus kinase 2 with a valine to phenylalanine substitution at amino acid 617 (JAK2 V617F) mutation. --- V617F ---
This inclusion criterion will not apply to the subset of participants in Cohorts 10 and 11 that must be negative for the JAK2 V617F mutation - Are ≥ 18 years of age - Have given written informed consent prior to any study-specific procedures - Have adequate organ function, including: Hepatic: Direct bilirubin ≤1.5 times upper limits of normal (ULN), alanine transaminase (ALT), and aspartate transaminase (AST) ≤2.5 times ULN; Renal: Serum creatinine ≤1.5 times ULN; Bone Marrow Reserve: Absolute neutrophil count (ANC) ≥1000/microliter (mcL), platelets ≥50,000/mcL for participants with ET or PV and ≥25,000/mcL for participants with MF - Have a performance status of 0, 1, or 2 on the Eastern Cooperative Oncology Group (ECOG) scale - Have discontinued all previous approved therapies for Myeloproliferative Neoplasms (MPNs), including any chemotherapy, immunomodulating therapy (for example, thalidomide, interferon-alpha), immunosuppressive therapy (for example, corticosteroids >10 mg/day prednisone or equivalent), radiotherapy, and erythropoietin, thrombopoietin, or granulocyte colony stimulating factor for at least 14 days and recovered from the acute effects of therapy. --- V617F ---
An exception to this criterion will be allowed for participants with a prior history of Budd-Chiari Syndrome who are being treated with warfarin or one of its derivatives - Have received a hematopoietic stem cell transplant - Have a second primary malignancy that in the judgment of the Investigator and Sponsor may affect the interpretation of results - Have an active fungal, bacterial, and/or known viral infection including human immunodeficiency virus (HIV) or viral (A, B, or C) hepatitis (screening is not required) - Have a history of congestive heart failure with New York Heart Association (NYHA) Class >2 (NYHA Class 1 and 2 are eligible), unstable angina, recent myocardial infarction (within 6 months prior to administration of study drug), or documented history of ventricular arrhythmia Inclusion Criteria: - Have a diagnosis of polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF) as defined by the World Health Organization (WHO) diagnostic criteria for myeloproliferative neoplasms (Swerdlow et al. 2008) and meet the following additional subtype specific criteria: - PV: have failed or is intolerant of standard therapies or refuses to take standard medications - ET: have failed or is intolerant of standard therapies or refuses to take standard medications - MF (participants with MF must meet at least 1 of the following): have intermediate 1, intermediate 2, or high-risk MF according to the Dynamic International Prognostic Scoring System (DIPPS Plus) for Primary Myelofibrosis (Gangat et al. 2011); or have symptomatic MF with spleen greater than 10 centimeter (cm) below left costal margin; or have post-polycythemic MF; or have post-ET MF - All PV, ET, and MF participants must meet the following criteria: o Have a quantifiable level of janus kinase 2 with a valine to phenylalanine substitution at amino acid 617 (JAK2 V617F) mutation. --- V617F ---
