NCT ID: NCT04243122 Completed - Clinical trials for Primary Myelofibrosis

Assessing Feasibility of Thromboprophylaxis With Apixaban in JAK2-positive Myeloproliferative Neoplasm Patients

AIRPORT-MPN
Start date: February 17, 2021
Phase: Phase 2
Study type: Interventional

Myeloproliferative neoplasms (MPNs) are blood disorders that occur when the body makes too many white or red blood cells, or platelets. This overproduction of blood cells in the bone marrow can create problems for blood flow and lead to various symptoms. One of the major problems is the formation of blood clots. These may form in the veins of a patient's legs or arms where they cause leg or arm pain, swelling or difficulty walking. These clots may travel to the lung and then cause chest pain, shortness of breath and sometimes death. Blood clots can also lead to poor or no blood flow to one's heart, brain, or other organs, causing damages that cannot be easily or ever repaired, such as stroke or heart attack. Patients diagnosed with certain types of MPN are associated with a higher risk of developing blood clots and related complications. For this reason, MPN patients are usually treated with low-dose aspirin, a common drug used for blood clot prevention, on long-term basis to prevent the formation of blood clots and other complications. However, recent studies also show that the risk of blood clots remains elevated in MPN patients treated with aspirin, and there may not be improvement or reduction in fatal or other events that are associated with blood clots. In addition, since this medical condition is rare, so there's a lack of studies done with high quality results to help physicians decide the best treatment plan for these patients. The study drug, apixaban, is a new type of orally-taken blood thinner that has been shown to be effective and safe for prevention and treatment of blood clots in various patient populations. The investigators will evaluate whether apixaban is safer and/or better at preventing blood clots and other complications in MPN patients compared to aspirin.

NCT ID: NCT04173494 Completed - Clinical trials for Primary Myelofibrosis

A Study of Momelotinib Versus Danazol in Symptomatic and Anemic Myelofibrosis Participants (MOMENTUM)

Start date: February 7, 2020
Phase: Phase 3
Study type: Interventional

MOMENTUM is a randomized, double-blind, active control Phase 3 trial intended to confirm the differentiated clinical benefits of the investigational drug momelotinib (MMB) versus danazol (DAN) in symptomatic and anemic participants who have previously received an approved Janus kinase inhibitor (JAKi) therapy for myelofibrosis (MF). The purpose of this clinical study is to compare the effectiveness and safety of MMB to DAN in treating and reducing: 1) disease related symptoms, 2) the need for blood transfusions and 3) splenomegaly, in adults with primary MF, post-polycythemia vera MF or post-essential thrombocythemia MF. The study is planned in countries including, but not limited to: Australia, Austria, Belgium, Bulgaria, Canada, Czech Republic, Denmark, France, Germany, Hungary, Israel, Italy, New Zealand, Poland, Romania, Singapore, South Korea, Spain, Sweden, Taiwan, United Kingdom (UK) and United States (US). Participants must be symptomatic with a Myelofibrosis Symptom Assessment Form (MFSAF) version (v) 4.0 Total Symptom Score of >= 10 at screening, and be anemic with hemoglobin (Hgb) < 10 gram/deciliter (g/dL). For participants with ongoing JAKi therapy at screening, JAKi therapy must be tapered over a period of at least 1 week, followed by a 2-week non-treatment washout interval prior to randomization. Participants will be randomized 2:1 to orally self-administer blinded treatment: MMB plus placebo or DAN plus placebo. Participants randomized to receive MMB who complete the randomized treatment period to the end of Week 24 may continue to receive MMB in the open-label extended treatment period to the end of Week 204 (a total period of treatment of approximately 4 years) if the participants tolerates and continues to benefit from MMB. Participants randomized to receive DAN may cross-over to MMB open-label treatment in the following circumstances: at the end of Week 24 if they complete the randomized treatment period; or at the end of Week 24 if they discontinue treatment with DAN but continue study assessments and do not receive prohibited medications including alternative active anti-MF therapy; or at any time during the randomized treatment period if they meet the protocol-defined criteria for radiographically confirmed symptomatic splenic progression. Participants randomized to receive DAN who are receiving clinical benefit at the end of Week 24 may choose to continue DAN therapy up to Week 48. The comparator treatment, DAN, is an approved medication in the US and in some other countries and is recommended by national guidelines as a treatment for anemia in MF.

NCT ID: NCT04051307 Completed - Polycythemia Vera Clinical Trials

Start date: July 10, 2019
Phase: Phase 1/Phase 2

NCT ID: NCT03907436 Completed - Myelofibrosis Clinical Trials

The NUTRIENT Trial (NUTRitional Intervention Among myEloproliferative Neoplasms): Feasibility Phase

NUTRIENT
Start date: October 1, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether MPN patient are able to adhere to a dietary intervention. Participants will be randomized to one of two healthy diets. Participants will receive in person dietician counseling and online curriculum. Adherence will be measured using online surveys and phone diet recalls. Changes in inflammatory markers in blood will also be measured at 5 time points during this 15 week study.

NCT ID: NCT03895112 Completed - Clinical trials for Primary Myelofibrosis

MPN-RC 118 AVID200 in Myelofibrosis

Start date: February 15, 2019
Phase: Phase 1
Study type: Interventional

Increased levels of TGF-β1 were detected in serum, plasma and BM and positively correlated with both grade of BMF and extent of leukemic cell infiltration in the marrow. TGF-β likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. AVID200 is a drug that targets TGF-β1 and TGF-β3. The study team hypothesizes that inhibiting the TGF-β signaling pathway in MF will decrease the fibrogenic stimuli leading to myelofibrosis and concomitantly interrupt myeloproliferation and restore normal hematopoiesis. This is a first in human, open-label, multicenter, Phase I/Ib trial of AVID200. Patients must have intermediate-2 or higher primary myelofibrosis (PMF), post-essential thrombocythemia or polycythemia-vera related MF (Post ET/PV MF). This study will enroll up to 24 patients. AVID200 is delivered by IV infusion on day 1 of each 3 week cycle.

NCT ID: NCT03745378 Completed - Myelofibrosis Clinical Trials

Secondary Cancers in Myeloproliferative Neoplasms (MPN-K Study)

MPN-K
Start date: May 15, 2018
Phase:
Study type: Observational

The incidence of secondary cancer (SC) in patients with myeloproliferative neoplasms (MPN) is high and comparable to that of thrombosis. However, the identification of patient subgroups that might be at increased susceptibility of developing SC has not been systematically addressed. This international case-control study (MPN-K) is aimed to elucidate the prognostic role of JAK2V617F mutation in predicting the occurrence of SC in patients with classical MPN, polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis (MF)

NCT ID: NCT03624335 Completed - Clinical trials for Hyperbilirubinemia, Neonatal

Influence of Umbilical Cord Clamping Time in the Newborn

Start date: March 23, 2015
Phase: N/A
Study type: Interventional

This study compares two umbilical cord clamping times; the early one, up to a minute (ECC) and the late or delayed one, when the cord stop beating (DCC). The additional blood volume delivered to the newborn from the placenta - placental transference - by delaying umbilical cord ligation, increases the contribution of neonatal iron with increased iron stores in the infant, without increasing neonatal morbidity.
