Title: Determination of the Optimal Prophylactic Platelet Dose Strategy to Prevent Bleeding in Thrombocytopenic Patients (A TMH CTN Study)
Brief Summary: The primary objective of this study is to compare the three study arms of lower, medium, and higher dose platelet therapy with respect to the percentage of patients experiencing at least one episode of Grade 2 or higher bleeding as determined by the Platelet Dose Trial Bleeding Scale (Grade 2 bleeding corresponds to bleeding that is moderate, but not severe enough to warrant red blood cell transfusion).

There are a number of secondary endpoints related to platelet transfusions, hemostasis, and other concerns. The four most important secondary endpoints will compare the three study arms with respect to the following outcomes: 1) platelet utilization rates (total number of platelets transfused x 10 \^11); 2) number of platelet transfusion events (frequency of transfusions); a transfusion event would be defined as each separate platelet transfusion issued by the study site's transfusion service; 3) highest category of bleeding during time of study (Platelet Dose Trial Bleeding Scale Grades less than or equal to 1, 2, 3, or 4 by arm); and 4) bleeding severity based on number of days with bleeding (total days of bleeding and bleeding/thrombocytopenic day), intensity of bleeding, and number of sites with bleeding (if such a severity score has been validated and published by the time the study is completed).


Options:
A: Inclusion Criteria:

* Adult subjects (18 years of age or older) with advanced MDS, sAML/MDS, or de novo AML with \>=10% and \<=50% blasts in bone marrow. Peripheral blood blast change over time should not be suggestive of highly proliferative disease (as judged by the investigator).
* Subjects must be dependent on regular platelet transfusions or have a platelet count taken within the 4 weeks prior to randomization that is \<30 Gi/L.
* Subjects must be relapsed, refractory or ineligible to receive standard treatment options of azacitidine and decitabine and must be relapsed, refractory or ineligible to receive intensive chemotherapy or autologous/allogeneic stem cell transplantation. A subject may be considered relapsed/refractory to a standard treatment if it is discontinued due to lack of efficacy. For subjects ineligible for standard treatments, it is permissible to start one of these standard treatments while on study medication if the Investigator considers that the subject becomes eligible during the course of the study.
* Prior therapy with demethylating agents (azacitidine or decitabine), lenalidomide or IL-11(oprelvekin) must have been completed at least 4 weeks before Day 1; antithymocyte/antilymphocyte globulin, intensive chemotherapy, or autologous/allogeneic stem cell transplantation must have been completed at least 2 months before Day 1. If a subject must discontinue a course of therapy due to lack of efficacy, the washout periods listed above do not apply (and the patient may be screened and randomized immediately if other eligibility criteria are met).
* Subjects must have platelet count and platelet transfusion data available over a period of 4 weeks prior to randomization.
* Subjects with advanced MDS, sAML/MDS, or de novo AML must have stable disease indicated by a doubling time of peripheral blast counts \>7 days during screening.
* During the 4 weeks prior to randomization, subjects must have a baseline bone marrow examination including the following:
* cytomorphology to confirm bone marrow blasts between 10-50%,
* cytogenetics (provide only most prevalent abnormal clone),

The results of the above tests are required prior to subject randomization.

* Supportive/palliative therapies such as cytokines (except for IL-11; oprelvekin), valproic acid, all-trans retinoic acid or mild chemotherapy are allowed if part of the local SOC, provided those therapies have been at a stable dose for 4 weeks. If the subject chooses to discontinue these therapies prior to study entry, they must be completed 4 weeks prior to enrollment into this study, unless the therapy is discontinued due to lack of efficacy. Erythropoiesis-stimulating agents (ESAs) in anemic subjects or granulocyte colony-stimulating factor (G-CSF) in subjects with severe neutropenia and recurrent infections are allowed during the study as per accepted standards. Subjects who enter the study on ESAs or G-CSF should continue at the same dose schedule until the optimal dose of study medication has been established.
* ECOG Status 0-3.
* Subject is able to understand and comply with protocol requirements and instructions.
* Subject has signed and dated informed consent.
* Prothrombin time (PT/INR) and activated partial thromboplastin time (aPTT) must be within 80 to 120% of the normal range at baseline.
* Adequate baseline organ function defined by the criteria below:
* total bilirubin (except for Gilbert's Syndrome) \<= 1.5xULN
* ALT and AST \<= 3xULN
* creatinine \<= 2xULN
* albumin must not be below the lower limit of normal (LLN) by more than 20%.
* Subject is practicing an acceptable method of contraception (documented in chart).
