NCT ID: NCT06371573 Completed - Clinical trials for Primary Myelofibrosis

Ultrasound Examination for Spleen Volume Evaluation in Myeloproliferative Neoplasms

Start date: April 20, 2017
Phase:
Study type: Observational

Adult patients (>18 years) with newly diagnosis of Ph negative myeloproliferative neoplasms (MPNs) according to WHO 2016 criteria, will be recruited to this study. This study is the result of the collaboration the Hematology Division of Federico II University Medical School of Naples (Italy), that performed the US investigation and the IRCCS SYNLAB SDN where the patients carried out MR. The study is conducted in accordance with the Declaration of Helsinki. All subjects gave informed consent to receive both US and MR scans of the spleen. All spleen US scans were performed by the same operator (with>10 years of experience in abdominal US), who used an EPIQ 5 Philips instrument with a 1-5 MHz broadband curvilinear probe. The spleen was scanned in patients who were fasting, in the longitudinal and transverse planes by using an intercostal approach, a subcostal approach, or both. The patient was placed in a supine or right-sided position until complete organ visualization was achieved. Perimeter, longitudinal diameter (LD), and area, defined as the maximum measurements with splenic borders and angles clearly defined, were measured, and SV (in milliliters) was calculated automatically. For each subject, the mean value of 3 measurements repeated on the same imaging session was calculated and recorded for final analysis. Within two weeks from the US, each patient underwent an MRI of the upper abdomen to evaluate the splenic volume. MRI examinations were performed using a 3T Biograph mMR scanner (Siemens Healthcare, Erlangen, Germany) with 4-channel flex phased-array body coil. Routine clinical abdominal MRI acquisition includes coronal T2W Half-Fourier Acquisition Single-shot Turbo spin Echo imaging (HASTE), axial T1 Dual-echo FSE, axial T2 TSE Fat Sat, and an axial diffusion-weighted imaging (DWI). The DWI includes an apparent diffusion coefficient (ADC) map that was automatically generated at the time of acquisition. At last, an isotropic 2mm3 axial Volumetric Interpolated Breath-hold Examination (VIBE) sequence for SV evaluation was acquired. For the latter, attention was paid to optimize the field of view to the spleen, in order to reduce patient's apnea and possible respiratory artifacts. A radiologist with mote than 10 years of experience in abdominal MRI reporting performed measurement of the three orthogonal diameters of the spleen for each patient. Subsequently, SV was calculated using ITK-SNAP software and semi-automatic 3D segmentation approach, firstly based on a signal threshold.

PREVALENCE STUDY OF PNH CLONES IN PATIENTS WITH NEOPLASIES

Start date: November 1, 2017
Phase:
Study type: Observational

Multicenter prevalence study of the PNH clone (paroxysmal hemoglobinuria nocturnal) in SMP Ph-. This multicenter, prospective study aims to evaluate the presence of an PNH clone in patients with a confirmed diagnosis of myeloproliferative neoplasia Phcon or without mutations in the 3 main genes involved in this disease (JAK2, MPL, and Cal-R),but showing signs of ongoing hemolysis or particular clinical conditions. To this end, a multicolor flow cytometric test will be used to evaluate the presence of deficient GPI molecules in granulocytic, monocytic and other cells erythrocyte (flow cytometric test, based on the use of the FLAER reagent in peripheral blood samples). The study will be conducted at clinical hematology centers in the wider area of the Romagna and at other Italian hematology clinical centers, where and analyzed the peripheral blood samples and clinical data to be included in the study. The participating centers will carry out the flow cytometric diagnostic test at i own reference laboratories, while the biological material for subsequent studies genetic-molecular type (next generation sequencing) will be analyzed centrally at the Biosciences laboratory of the IRST IRCCS only for cases testing positive for the presence of the PNH clone. Clinical information will be collected for each patient enrolled in the study necessary for the classification of the case and all the laboratory data necessary for achievement of the objectives of the study. The main objective of the study is to evaluate the prevalence of PNH clones in patients with a confirmed diagnosis of myeloproliferative neoplasm Ph- with or without mutations affecting the 3 main genes involved in this disease (JAK2, MPL, e Cal-R), but showing signs of ongoing hemolysis or particular clinical conditions. Secondary objectives of the study are: - correlate the characteristics of the PNH clone with the clinical characteristics and laboratory of myeloproliferative neoplasms Ph- (the presence of phenomena thrombotics, the disease state, the DIPSS prognostic score index, and the state mutational). · characterize the genomic architecture of the cases using NGS technology positive results

NCT ID: NCT04942730 Completed - Clinical trials for Myelodysplastic Syndromes

Benadamustine, Fludarabine and Busulfan Conditioning in Recipients of Haploidentical Stem Cell Transplantation (FluBuBe)

FluBuBe
Start date: January 21, 2021
Phase: Phase 2
Study type: Interventional

Haploidentical hematopoietic stem cell transplantation irrespective of the conditioning and graft-versus-host disease prophylaxis is associated with high frequency of primary and secondary graft failure. Different technologies of with replete or depleted graft are associated with 10-20% of graft failures. Fludarabine and busulfan conditioning is the most commonly used approach for a variety of disease. Furthermore combination of fludarabine and bendamustine was sufficient to facilitate engraftment in patients with chronic lymphocytic leukemia and lymphomas. The aim of the study is to evaluate whether addition of bendamustine to fladarabine and busulfan conditioning reduces the risk of primary graft failure after haploidentical allograft.

NCT ID: NCT04744974 Completed - Clinical trials for Myeloproliferative Neoplasm

Remotely Administered Diet Intervention to Impact Symptom Burden in Myeloproliferative Neoplasm

Start date: January 21, 2021
Phase: Phase 2
Study type: Interventional

Myeloproliferative Neoplasm (MPN) is a chronic blood cancer without cure. The major clinical issues in MPN are 1) an increased risk of blood clots 2) symptoms thought to be driven by chronic inflammation which in some cases can be debilitating and 3) progression to acute leukemia. The current management of MPN focuses on preventing blood clots and relieving symptoms. However, treatments that reduce symptoms such as JAK inhibitors are limited to late stage MPN patients and have significant side effects including immunosuppression, reduction in platelets, and increased risk of skin cancer. Therefore, low risk interventions are sorely needed for MPN patients that can reduce symptoms. Diet represents a low risk way to reduce inflammation, specifically a Mediterranean diet has been found to reduce inflammation in cardiovascular disease. There has been a recently completed clinical trial that demonstrated MPN patients can adopt a Mediterranean diet if given dietician counseling and curriculum. However, in order to reach a larger group of people a fully remotely administered study is necessary. This is a feasibility study to determine.

NCT ID: NCT04666025 Completed - Clinical trials for Acute Myeloid Leukemia

SARS-CoV-2 Donor-Recipient Immunity Transfer

Start date: September 23, 2020
Phase:
Study type: Observational

This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. This study may provide critical information for medical decision-making and possible immunotherapy interventions in immunocompromised transplant recipients, who are at high risk for COVID19 severe illness.

NCT ID: NCT04629430 Completed - Multiple Myeloma Clinical Trials

Effects of Prebiotics on Gut Microbiome in Patients Undergoing HSCT

HCTDiet
Start date: February 19, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to see whether hematopoietic stem cell transplant (HSCT) patients can consistently eat a diet rich in prebiotics. This type of diet may be helpful in maintaining diversity in the gastrointestinal (GI) system and therefore potentially decreasing risk of other GI problems.

NCT ID: NCT04605211 Completed - Clinical trials for Chronic Myeloid Leukemia

A Distress Reduction Intervention for Patients With BCR-ABL-Negative MPNs or CML on Tyrosine Kinase Inhibitors

Start date: September 18, 2020
Phase: N/A
Study type: Interventional

This trial looks at how well a distress reduction intervention, called "Being Present", works to improve the quality of life of patients with BCR-ABL-negative myeloproliferative neoplasms (MPNs) or chronic phase chronic myeloid leukemia (CP-CML) who are taking tyrosine kinase inhibitors (TKIs) and their caregivers. Mindfulness meditation is the practice of repeatedly bringing attention back to the immediate experience and may help people cope with various types of illness, stress, and worry. This may help patients and caregivers to gradually learn to disconnect from reacting to and dwelling on the past and future and instead fully experiencing the present moment.

NCT ID: NCT04416438 Completed - Clinical trials for Myeloproliferative Neoplasm

COVID-19 Epidemic and Patients With Myeloproliferative Neoplasias

COVIM
Start date: May 18, 2020
Phase:
Study type: Observational

The classic myeloproliferative neoplasias (MNP), including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) or secondary to PV or ET, are among the most frequent of malignant hemopathies, with overall prevalence estimated at around 10,000 patients followed in France. Due to the median age of patients around 65, the frequency of cardiovascular complications of these thrombogenic diseases and the impact of cytoreductive treatments on immune cells, these patients are considered to be at risk of developing forms severe of COVID-19. This study will assess the impact of MNPs on the risk of developing a severe form of COVID-19, identify new risk factors linked to the disease as well as the impact of treatments for MNPs according to their pharmacological class.

NCT ID: NCT04192916 Completed - Clinical trials for Myeloproliferative Neoplasm

Use of Direct Oral Anticoagulants (DOACs) in Patients With Ph-negative Myeloproliferative Neoplasms

MPN-DOACs
Start date: September 1, 2019
Phase:
Study type: Observational

Patients with myeloproliferative neoplasms (MPN) are predisposed to have an increased thrombotic and hemorrhagic risk and, in this context, the use of newly approved direct oral anticoagulants (DOACs) may have improved bleeding risk compared to warfarin use. However, the published experience is very limited and does not allow any conclusion. In the cohort of patients with MPN and venous thromboembolism (VTE) of European Leukemia-net, only 3.3% of patients had been treated with DOACs. Similarly, in a recent publication of a series of 760 patients with single-center MPN, only 25 (3.3%) were treated with a DOAC (13 for atrial fibrillation and 12 for thrombotic events). While it is known that the risk of thrombotic recurrence and haemorrhagic event during warfarin treatment is about 30% at 5 years from the first event, the actual risk of such events in MPN patients is not known. The aim of the present study is therefore to obtain information on patients with MPN treated with DOAC for atrial fibrillation (AF) and VTE. This is an international multi-center retrospective survey aimed at describing the efficacy / safety of DOAC in the prevention of: - cardioembolic stroke in patients with MPN with AF - recurrent thrombosis in patients with MPN with VTE - major bleeding in all patients with MPN. The results will allow to design future prospective studies that evaluate the benefit / risk profile of DOAC compared to warfarin in these pathologies characterized by high risk of thrombosis and, in some subgroups, of bleeding.
