E.1.1.1 | Medical condition in easily understood language |
MPNs are a group of diseases of the bone marrow which result in the
production of excess cells. They are related to and may evolve into
leukemia. |
neoplasie mieloproliferative sono patologie del midollo osseo che determinano una produzione eccessiva di cellule nel sangue. Queste sono correlate a leucemie. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess the activity of LY2784544 therapy administered once daily, as measured by objective response rate, in patients with the myeloproliferative neoplasms (MPNs), polycythemia vera (PV), essential thrombocythemia (ET), or myelofibrosis (MF). |
l'obiettivo primario di questo studio è valutare l'attività della terapia con LY2784544 somministrata una volta al giorno, misurata tramite la percentuale di risposta obiettiva, nei pazienti con le seguenti neoplasie mieloproliferative (MPN): Policitemia Vera (PV), Trombocitemia Essenziale (TE) o Mielofibrosi (MF). |
|
E.2.2 | Secondary objectives of the trial |
to assess the individual components of response criteria including changes in spleen and liver measurement, changes in JAK2 V617F mutant allele burden, changes in blood counts, changes in bone marrow histology, and changes in transfusion or phlebotomy requirements by MPN subtype
•to document any change in patient-reported or physician assessment of symptom burden by MPN subtype
•to estimate the PK parameters of LY2784544 by dose and explore for potential relationship with response for each MPN subtype
•to document any change in frequency of thrombotic/hemorrhagic events after treatment with LY2784544 by MPN subtype
•to assess time-to-event measures, including time to best response and duration of response for each MPN subtype•to describe response to LY2784544 in patients with wild-type JAK2 |
Caratterizzare il profilo di sicurezza e tossicità di LY2784544 per sottotipo di MPN• Valutare i singoli componenti dei criteri di risposta compresi i cambiamenti delle dimensioni di milza e fegato, i cambiamenti nel carico di alleli mutati JAK2 V617F, le variazioni nella conta ematica, i cambiamenti nell'istologia del midollo osseo e i cambiamenti nella necessità di trasfusioni o flebotomia per sottotipo MPN• Documentare eventuali cambiamenti nella valutazione della sintomatologia riferita dal paziente o valutata dal medico per sottotipo di MPN• Stimare i parametri di farmacocinetica di LY2784544 per dose • Documentare eventuali variazioni nella frequenza di eventi trombotici/emorragici dopo il trattamento con LY2784544 per sottotipo di MPN• Valutare le misure time-to-event, per ogni sottotipo di MPN•Descrivere la risprisposta a LY2784544 nei pazienti con JAK2 wild-type |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients must have a diagnosis of PV, ET, or MF as defined by the World Health Organization diagnostic criteria for MPNs. Patients must have discontinued all previous approved therapies for MPNs. Patients must be greater than 18 years of age and both males and females can be enrolled. Patients must have adequate bone marrow reserve: absolute neutrophil count ≥1000/mcL, platelets ≥50,000/mcL for patients with ET or PV, and ≥25,000/mcL for patients with MF. |
i pazienti devono avere una diagnosi di PV, TE o MF come definite dai criteri diagnostici dell'Organizzazione Mondiale della Sanità per le MPN. I pazienti devono aver interrotto tutte le terapie precedenti approvate per la MPN. I pazienti devono avere un'età superiore ai 18 anni e possono essere arruolati sia i maschi sia le femmine. I pazienti devono avere un'adeguata riserva di midollo osseo: conta assoluta dei neutrofili ≥ 1000/mcl, piastrine ≥ 50.000/mcl per i pazienti con TE o PV, e ≥ 25.000/mcl per i pazienti con MF. |

E.4 | Principal exclusion criteria |
Patients will be excluded if they have a corrected QT (QTc) interval >470 msec, are currently being treated with agents that are metabolized by CYP3A4 or CYP2B6 with a narrow therapeutic margin, are currently being treated with warfarin, have received a hematopoietic stem cell transplant, or have a history of congestive heart failure with New York Heart Association Class >2, unstable angina, recent myocardial infarction or documented history of ventricular arrhythmia. |
I pazienti saranno esclusi se hanno un intervallo QT corretto (QTc) > 470 msec, sono attualmente in trattamento con farmaci metabolizzati da CYP3A4 o CYP2B6 con un margine terapeutico limitato, sono attualmente in trattamento con warfarina, hanno ricevuto trapianto di cellule staminali ematopoietiche, o hanno un’anamnesi di insufficienza cardiaca congestizia con Classe della New York Heart Association > 2, angina instabile, recente infarto del miocardio o aritmia ventricolare documentata. |

E.5 End points |
E.5.1 | Primary end point(s) |
This study is designed to assess evidence of efficacy of LY2784544 and
at least 1 out of 10 patients in each cohort must demonstrate objective
response in order for the regimen to be considered for further study. |
nello studio saranno arruolati circa 125 pazienti con MPN, suddivisi in coorti sulla base del sottotipo di MPN. Il disegno dello studio è volto a valutare l'evidenza dell'efficacia di LY2784544, e almeno un paziente su 10 in ogni coorte deve esibire una risposta obiettiva affinché il regime possa essere considerato per ulteriori studi. |

Bone Marrow Core Biopsy and Aspirate with karyotype evaluation, as
well as physician assessment of response will be done in Cycle 6 and
every 6th cycle thereafter (i.e., Cycle 12, 18, 24, etc) or if evidence of
molecular remission.
CT or MRI of Spleen and Liver (may include contrast), as well as
physician assessment of response will be collected only in Cycles 3, 6, 9,
12 and then every 6th cycle. |
La Biopsia del midollo osseo e L aspirato per la valutazione del cariotipo,così come valutazione mediche della risposta saranno effettuate al ciclo 6 ed ogni 6 cicli o in presenza di remissione cellulare. |
