E.4 | Principal exclusion criteria |
[13] Are currently enrolled in, or discontinued within the last 14 days from a clinical trial involving an investigational product or non-approved use of a drug or device, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study. [14] Have a corrected QT (QTc) interval >470 msec using Bazett's formula. [15] Have serious preexisting medical conditions that, in the opinion of the investigator would preclude participation in the study (for example a gastrointestinal disorder causing clinically significant symptoms such as nausea, vomiting, and diarrhea, or malabsorption syndrome). [16] Are currently being treated with agents that are metabolized by CYP3A4 with a narrow therapeutic margin (for example, alfentanil, cyclosporine, diergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, and tacrolimus) or CYP2B6 (for example, cyclophosphamide, ifosfamide, tamoxifen, efavirenz, propofol, methadone, and bupropion). [17] Are currently being treated with warfarin or 1 of its derivatives which is known to alter levels of protein C or protein S. An exception to this criterion will be allowed for patients with a prior history of Budd-Chiari Syndrome who are being treated with warfarin or 1 of its derivatives. [18] Have received a hematopoietic stem cell transplant. [19] Have a second primary malignancy that in the judgment of the Investigator and Sponsor may affect the interpretation of results. [20] 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). [21] Have a history of congestive heart failure with New York Heart Association 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.

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. The primary efficacy measure is objective response as defined by the European LeukemiaNet Response Criteria for ET and PV and the International Working Group Consensus Criteria for Treatment Response in MF. A responder in patients with ET or PV is defined as any patient who exhibits a complete response or partial response for molecular, clinicohematologic, or histologic assessments. A treatment response in patients with MF is defined as any patient who exhibits a complete remission, partial remission, or clinical improvement according to the IWG criteria. Molecular and histologic responses for patients with MF will be assessed in the same way as defined for patients with ET and PV. Best response is determined from the sequence of responses assessed. The Sponsor or designee will collect and store all bone marrow biopsies and spleen images on all enrolled patients throughout the study. A central review of bone marrow histology including fibrosis grading and reticulin staining will be performed by a blinded, independent panel of pathologists. An independent review of spleen images may be performed if a response to LY2784544 is observed.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
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. |
|
E.5.2 | Secondary end point(s) |
Secondary Efficacy Measures Molecular response rate: JAK2 V617F mutant clone burden will be used to determine molecular response. Also called mutant allele burden. Hematological improvement rate: To determine clinicohematologic response based on complete blood count in conjunction with spleen size and disease related symptoms (preexisting conditions and adverse events). Decrease in spleen size: To determine change in spleen size based on physical exam and imaging. Measurements will be used conjunction with blood counts and disease related symptoms for clinicohematologic response. Bone marrow biopsy histology: To determine histological response. Bone marrow fibrosis grade will be recorded and standard bone marrow histology will be evaluated. Number of thrombotic or hemorrhagic events: To determine if the number of these events is decreased as compared to an individual’s historical records. Coagulation factor status: Measured by the following analytes: prothrombin time/international normalized ratio, activated partial thromboplastin time, free protein S, total protein S, Factor II and V functional assay, C4b binding protein. Frequency of phlebotomies and transfusions: To determine if the need for and frequency of these procedures is decreased as compared to an individual’s historical records and to determine the effect on the rate of dependence on these procedures. Duration of response: (Relapse-free survival for patients who achieve CR). From the time response was achieved to disease progression or death. Time to best response: Time from study enrollment to best response (including partial response). Health outcome measurements: To assess ability of study treatment to modify health outcome measures using the 6-item physician assessment and patient-reported data from the MPN-SAF, ADL/IADL, and EQ-5D questionnaires. IPSS, DIPSS, and DIPSS Plus: To determine the effect of study treatment on DIPSS, DIPSS Plus, and disease risk modification. Time to treatment failure: Time from study enrollment to the first observation of objective progression or death from any reason or early , discontinuation of study therapy. Time to disease progression: Time from the date of study enrollment to the date of first observation of objective progression. Progression-free survival: Time from the date of study enrollment to the date of first observation of objective progression or death from any cause. Abbreviations: CR = complete response/remission; DIPSS = Dynamic International Prognostic Scoring System; EQ-5D = EuroQol – 5 dimensions; IPSS = International Prognosis Scoring System; MPN SAF = Myeloproliferative Neoplasm Symptom Assessment Form
