Filter by: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.
To evaluate the pharmacokinetic Characteristics of two formulations of Jaktinib Hydrochloride Tablets in Healthy Adult Volunteers
The prospective multicenter observational cohort study will be offered consecutively to any patient with primary or secondary myelofibrosis or with Polycythemia Vera who has initiated therapy with ruxolitinib, prescribed as part of the normal course of care and completely independent of study participation. The main purpose is to assess adherence to ruxolitinib using the ARMS questionnaire. Each individual patient will be administered the questionnaire at the first convenient opportunity, regardless of when ruxolitinib is started, and again after 4, 8, 12, 24, and 48 weeks, in conjunction with drug procurement.
TQ05105 is a class 1 new drug with a new chemical structure developed by Chia Tai Tianqing Pharmaceutical Group Co., Ltd. It is a Janus Kinase 2 （JAK2）inhibitor and can be used to treat JAK2 target-related diseases. This study is a randomized, open-label, single-center, two-cycle, two-crossover Phase I clinical trial evaluating the effect of food on the pharmacokinetics of TQ05105 tablets in healthy adult subjects. Pharmacokinetic effects and safety after oral administration of TQ05105 tablets.
Myelofibrosis (MF) is a rare blood cancer, characterized by extensive fibrosis (scarring) of the bone marrow. It is one of a group of cancers known as myeloproliferative neoplasms (MPNs) in which bone marrow cells that produce blood cells develop and function abnormally. This study will evaluate treatment patterns, treatment outcomes, healthcare resource utilization in adult participants with Myelofibrosis. Data from approximately 1000 participants will be collected. No participants will be enrolled in this study. Participants' charts will be reviewed. No drug will be administered as a part of this study. The duration of the observation period is up to 156 weeks. There is no additional burden for participants in this trial. All visits must be completed prior to data extraction and participants will be followed for up to 156 weeks.
Ruxolitinib is a Janus kinase (JAK) 1/2 inhibitor currently used in the treatment of Myelofibrosis (MF). Ruxolitinib confirmed improvements in splenomegaly, MF-related symptoms and survival benefit in COMFORT and JUMP studies. At present, the real-world data on the efficacy and safety of ruxolitinib in the treatment of MF in China is still insufficient. The aim of this study was to evaluate the efficacy and safety of ruxolitinib in patients with MF and to provide guidance for the usage of ruxolitinib in MF in China.This was a retrospective, multicenter study of MF patients who received ruxolitinib treatment in Shandong province from August 2012 to December 2021. Data were analyzed using SPSS. Overall survival (OS) and Event-free survival (EFS) were estimated using the Kaplan- Meier method.
This was a prospective, two-arm, non-interventional study of JAKAVI® (Ruxolitinib) in patients with myelofibrosis
This was an open-label, randomized, dose-finding study in patients with primary or secondary MF (Dynamic International Prognostic Scoring System [DIPSS] risk score of Intermediate-1 to High-Risk) who were previously treated with ruxolitinib. The study was designed to support a pacritinib dosage selection decision with evaluation of 3 dosages.
This was a phase 2, single-arm, open-label, non-randomised, multicentre, study to evaluate the efficacy and safety of Jaktinib in patients with myelofibrosis who were relapsed or refractory of ruxolitinib treatment.
This is a 2-part study. In Part 1, participants will be dosed at 2 different dose levels in order to select the RP2D for Part 2 of the study.
