Filter by:Indication Treatment of pediatric subjects with newly diagnosed advanced myelodysplastic syndrome (MDS) or juvenile myelomonocytic leukemia (JMML) prior to hematopoietic stem cell transplantation (HSCT). Objectives Primary Objective The primary objective is to assess the treatment effect on response rate (MDS: either complete remission [CR], partial remission [PR], or marrow CR; JMML: either clinical complete remission [cCR] or clinical partial remission [cPR]); at Cycle 3 Day 28 (each cycle is 28 days) and to compare against standard therapy using a matched-pairs analysis of historical data. Secondary Objective The secondary objective is to further evaluate safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of azacitidine in this subject population. Study Design This is a prospective, open-label, Phase 2 study consisting of 2 parallel experimental arms, one for each disease group: MDS and JMML. Each arm is designed based on Simon's Optimal 2 stage study design. The sample size has been calculated to allow evaluation of the response rate at 28 day-Cycle 3 Day 28 in each of the 2 disease groups. Each of the experimental arms will also individually be compared against a historical control arm using data retrospectively collected from the European Working Group of MDS in childhood (EWOG-MDS) registry by means of a matched-pairs analysis; matched for predefined subject baseline characteristics defined before any results from this study are known post Stage 1. If matched pair is not viable then other methodologies will be explored to evaluate and compare response rates reported in literature and also in registry database Twenty subjects with MDS and 35 JMML subjects evaluable for the primary endpoint (ie, subjects that receive at least 1 dose of investigational product [IP]) will be enrolled at approximately 45 centers in Europe. Each experimental arm has 1 interim analysis planned (at the end of Stage 1). If, during Stage 1 evaluation, less than 2 subjects are observed with a CR, PR, or marrow CR after 3 months of azacitidine in the first 9 subjects with MDS, then enrollment will be stopped. Similarly, if less than 3 subjects are observed with a cPR or cCR after 3 months of azacitidine in the first 18 subjects with JMML, then enrollment will be stopped.
This is a phase 1/2, uncontrolled, open-label, multicenter study in patients with MDS for whom no effective therapies currently exist.
Chronic anemia is the symptom most frequently found at diagnosis in low risk myelodysplastic syndrome. It generates an increased rate of morbidity and mortality in this population of patients whose median age is high and the rate of co-mobidities important. The historical treatment is limited to transfusion support with a significant impact on quality of life and the incidence of secondary haemosiderosis, which contributes to the emergence of co-morbidities, especially cardiovascular. Treatment with rHuEPO allows for overall erythroid response in 40-60% of patients treated. In this trial, the investigators intend to study the interest of a treatment with epoetin beta in patients with anemia <10 g / dL in the context of a myelodysplastic syndrome with IPSS score <1. In addition to studying the erythroid response, the investigators will measure the impact on quality of life and functional performance. Patients will receive epoetin beta (60 000UI/week). Response will be assessed after 12 and 24 weeks of treatment.
This phase II trial studies the side effects and best dose of nivolumab and azacitidine with or without ipilimumab when given together and to see how well they work in treating patients with acute myeloid leukemia that has not responded to previous treatment or has returned after a period of improvement or is newly diagnosed. Monoclonal antibodies, such as nivolumab and ipilimumab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab, azacitidine and ipilimumab may kill more cancer cells.
The purpose of this observational study is to compare overall survival in older adults with myelodysplastic syndromes (MDS) who receive reduced intensity conditioning hematopoietic stem cell transplant (RIC HSCT) versus those who do not receive HSCT.
The goal of this research study is to test a quality-of-life questionnaire called QUALMS-1 in patients with MDS. This is an investigational study. Up to 240 participants will be enrolled in this multicenter study. Up to 175 will take part at MD Anderson.
This multi center open label Phase 1b study is designed to evaluate the safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of glasdegib (PF-04449913) when combined with azacitidine in patients with previously untreated Higher Risk Myelodysplastic Syndrome (MDS), Acute Myeloid Leukemia (AML), or Chronic Myelomonocytic Leukemia (CMML). This clinical study includes two components: (a) a safety lead in cohort (LIC) and (b) an expansion phase with an AML cohort and an MDS cohort.
The dose-confirming part of this study, comprising at least 10 patients is designed as a single center, prospective, single arm, open label in patients who have failed or are unresponsive to Azacitidine (AZA) or Decitabine (they may also have additionally failed an Erythropoiesis Stimulating Agent (ESA) followed by a dose expansion part with at least 44 patients; the objective of the whole study being to assess the safety, efficacy, pharmacokinetics and pharmacodynamics of intravenously infused multiple doses of OPN-305 in low and intermediate-1 risk myelodysplastic syndrome (second and third line Lower risk MDS).
The study is designed as a three arm randomized Phase III, multicenter trial comparing two calcineurin inhibitor (CNI)-free strategies for Graft-versus-Host Disease (GVHD) prophylaxis to standard tacrolimus and methotrexate (Tac/Mtx) in patients with hematologic malignancies undergoing myeloablative conditioning hematopoietic stem cell transplantation.
There are currently no licensed drugs in the EU to treat thrombocytopenia in MDS patients classified as IPSS low/int-1. Prior studies with romiplostim (a TPO receptor agonist) in MDS found that baseline concentration of TPO as well as transfusion history were predictive of subsequent response in a retrospective model. The current prospective study has the aim to explore whether both pretreatment variables (endogenous TPO, TPO-level, platelet transfusion history) can predict the response to subsequent short-term treatment with romiplostim.
