Primary objective 1) To assess whether oncologic and hematologic patients develop a protective immunological response after pandemic Influenza A (H1N1) vaccine Secondary objectives 1. To compare the levels of antibody response against A (H1N1) influenza virus between oncologic and hematologic patients relative to a cohort of healthy volunteers 2. To assess the incidence of A (H1N1) infection in vaccinated oncologic and hematologic patients in comparison with a cohort of vaccinated healthy volunteers. To assess the clinical symptoms attributable to influenza infection in vaccinated oncologic and hematological patients and healthy volunteers. 3. To compare the levels of antibody response against A (H1N1) influenza virus between the following subgroups: patients with ongoing chemotherapy; patients who have completed the chemotherapy treatment; patients treated with autologous or allogeneic peripheral blood hematopoietic stem cell transplant (PBSCT) Study procedures: Onco-hematological patients will perform a blood sample collection before the vaccination, on day +21 after vaccination , on day +50 and on day +90. At the end of the collection, the investigators will perform immunological test to evaluate the antibody titer and the cellular response. The titer of antibodies against the vaccine strain will be measured in all samples by hemagglutination-inhibition (HI) assays with the use of turkey erythrocytes and according to EMEA guidelines. Response criteria will be the achievement of a protective title of HI test > 1:40. In addition, the investigators will evaluate: geometric mean titers and a fourfold titer increase compared with prevaccination titers. Cellular-mediated response will be analysed by flow-cytometry. A control cohort of healthy volunteers who received A(H1N1) vaccine will perform the same blood sample collection. Evaluation of clinical response: Oncologic and hematologic patients will be followed as outpatients or inpatients according to routine controls for their disease. In case that symptoms of the upper airways or influenza-like symptoms develop, the symptoms will be recorded in the clinical database, nasal and pharyngeal swaps will be performed according to the doctor who is taking care of the patient. In order to evaluate the clinical efficacy of the vaccination, the swaps will be tested for A (H1N1) influenza virus infection. No further studies will be performed after 3 months from the vaccination.
For patients with leukemia who have not responded to or have progressed after an initial response to standard therapy, therapeutic options are limited. Although responses to standard regimens do occur, durable remissions are achieved infrequently and current regimens are not curative in the majority of patients. Identification of active agents in patients with relapsed Acute Myeloid Leukemia (AML) ultimately affords the potential for use upfront as a component of induction regimens that may translate to improved outcome. Therefore, development of new agents is of critical importance. This study will look at a new, investigational agent, ON 01910.Na, to determine if it has the potential to help Patients with AML and Acute Lymphocytic Leukemia (ALL) and transformed Myeloproliferative Neoplasms.
Researchers will use abnormal blood and/or bone marrow cells, or materials derived from these abnormal cells, like DNA, RNA, protein or plasma, in laboratory studies. Toenail clippings will provide normal material like DNA for comparison with the abnormal material derived from the blood and/or bone marrow. The results of these studies will be correlated with subjects' disease symptoms and response to their experimental treatment. The MPD-RC researchers are interested in studying molecules from the blood and bone marrow, the exact molecules changing over time with the investigators choosing only the most promising for investigation. The investigators are attempting to better understand the causes of MPD and to develop improved methods for the diagnosis and treatment of these diseases. These syndromes carry a high risk of developing leukemia. It is important to continue to learn more about these blood cancers and to learn more about the effectiveness and potential side effects of various treatments. It is believed that further basic knowledge about these cancer cells as well as the effects of treatment will lead to the improvement of current therapies and the development of entirely new treatments for these diseases. The MPD-RC is hoping to determine if a number of laboratory tests (biomarkers) will allow for the prediction of response in future patients to the treatment they would receive.
