Filter by:The goal of this study is to assess the safety, tolerability, anti-tumor activity (efficacy), pharmacokinetics (PK), and pharmacodynamics (PD) of the agent RVU120 when administered to adult patients with relapsed or refractory acute myeloid leukemia (AML) or relapsed or progressing high-risk myelodysplastic syndrome (HR-MDS) and who have no alternative therapies available. The study consists of two parts. Part 1 will assess the safety and tolerability of the dosages given and the level of anti-tumor activity or clinical response. Based on the results from part 1 the study will continue to enrol patient into Part 2 which will continue to evaluate safety and tolerability and anti-tumor activity in a larger number of patients.
In an effort to reduce graft versus host disease (GVHD) and enhance graft versus leukemia (GVL) effect post allogenic hematopoietic stem cell transplantation (AHSCT), recent research has focused on host immune cell depletion. Frame shifting anti-thymocyte globulin (ATG) backwards to earlier days before days 0 can result in deeper host and less graft T-cell depletion, leading to better immune reconstitution. Preliminary data where 80% of the ATG dose is given on days -6,-5,-4 and 20% given on day -1, showed effective prevention of severe acute GVHD, chronic GVHD and favorable early immune reconstitution. We hypothesize that our 2 step ATG dosing platform when combined with standard tacrolimus and mini methotrexate can prevent grade III-IV acute GVHD and chronic GVHD, resulting in improvement of GVHD/relapse free survival at one year post transplant.
To assess the safety and efficacy of FLU-BU-MEL as a conditioning regimen for allogeneic hematopoietic stem cell transplantation in patients with untreated MDS-EB or IPSS-R that is intermediate-risk (>3.5 points), high-risk, or very high-risk. The investigators conducted this clinical trial.There will be three phases to this trial: screening, therapy, and follow-up. A) Screening phase: Qualified patients are screened for trial participation by a medical history, physical examination, laboratory testing, and disease evaluation after providing their informed consent. B) Treatment duration: patients receive allogeneic hematopoietic stem cell transplantation prepped with Flu-Bu-Mel in accordance with the protocol. C) Follow-up period: patients were checked on at the scheduled time to assess safety and efficacy. HSCT conditioning regiment: Flu 30 mg/m2/d d-6 days to d-2 9 (intravenously over two hours), : MEL 50 mg/m2/d intravenously, d-3 to d-2; BU 0.8 mg/kg/q6h d-6 to d-5 (intravenously, over 2 hours per drip). Fludarabine and melphalan do not require a dose adjustment based on body weight; however, if body mass index BMI> 25, ideal body weight (IBW) should be calculated (as BMI=25), and then determine Busulfan dosage based on corrected body weight (AIBW25). AIBW25=IBW+25% x (actual body weight - IBW)
This phase I trial tests the safety, side effects, and best dose of imetelstat in combination with fludarabine and cytarabine in treating patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) or juvenile myelomonocytic leukemia (JMML) that has not responded to previous treatment (refractory) or that has come back after a period of improvement (recurrent). Imetelstat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as fludarabine and cytarabine, 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 imetelstat in combination with fludarabine and cytarabine may work better in treating patients with refractory or recurrent AML, MDS, and JMML.
The aim of our study is to assess clinical & laboratory parameters of adult Egyptian myelodysplastic syndrome patients in upper Egypt, its correlation with disease-free survival, overall survival (OS) and acute leukemia transformation.
This study will evaluate orally administered RVU120, a novel small molecule Cyclin-dependent Kinase (CDK) 8/19 inhibitor, in terms of erythroid hematologic improvement (HI-E) and safety in participants with lower-risk myelodysplastic syndrome (MDS). Responding patients are eligible to continue treatment until loss of response/disease progression.
Three recent prospective "transplant/no transplant" studies concluded to an advantage of OS with transplantation in patients with high or intermediate-2 IPSS risk (not significant in Kröger's study). No prospective randomized trial has assessed the pre-transplant therapy in MDS patients yet but some information can be extracted from these 3 recent studies. In the French study (n=162), 72% patients with a donor received HSCT, previously treated by hypomethylating agent (HMA) in 71% of them. There was a trend to a better survival in patients achieving a complete remission with pre-graft therapy (HR: 0.55, p=0.088) and higher risk of death in unresponsiveness patients transformed into AML (HR: 2.36, p=0.008). In Nakamura's study (n=384), 83% of patients with a donor were transplanted, previously treated by HMA in 68%2. The multivariable Cox model for Overall Survival (OS) and Leukemia-free survival showed an excess risk in patients treated by HMA. Moreover, responders still have a higher risk of mortality as compared to patients who did not receive any pre-graft therapy (HR: 2.417, p=0.0054). In the German study, the aim was to initiate azacytidine at inclusion and to transplant patients after 4 cycles if a donor was identified1. Among 170 registered patients, 162 initiated 5-aza but 36% of them were "lost during this pre-graft therapy" before allocation to "donor" or "no-donor" arm, for different reasons including death (n=12). After 4 cycles of 5-aza, 79/81 patients "donor arm" were transplanted. The multivariable analysis showed remission status did not influence OS. Those 3 previous clinical trials thus suggest that a substantial number of patients planned for transplantation are not transplanted nowadays while no evidence of HMA benefit before HSCT has been clearly identified. This phase 2 study aim to assess the feasibility of upfront HSCT in patients with high risk MDS in order to increase the probability to be transplanted and to achieve a subsequent remission and better survival.
The purpose of this clinical trial is to evaluate the safety of TQB3454 tablets in patients with acute myeloid leukemia and myelodysplastic syndrome, and determine the phase II recommended dose.
The purpose of this single- arm, open-label, dose escalation and dose expansion phase I/II study is to evaluate the safety, tolerability, pharmacokinetic and preliminary efficacy of TGRX-814 in patients with hematological malignancies including non-Hodgkin lymphoma, acute myeloid leukemia, aute lymphoblastic leukemia and myelodysplastic syndromes.
The purpose of this study is to investigate the safety, tolerability, and preliminary efficacy of the combination treatment of hydroxyurea capsules and valproic acid capsules, or the combination treatment of 6-mercaptopurine tablets and valproic acid capsules in male and female patients aged 18 years or older with acute myeloid leukemia or high- risk myelodysplastic syndrome. The population to be studied is newly diagnosed AML patients who are considered unfit for standard induction chemotherapy, HR-MDS unfit/ineligible for standard treatment, and relapsed/refractory AML/HR-MDS patients who are considered unfit for standard therapy ,or are, for some reason, ineligible for another type of therapy. Clinically, hydroxyurea, valproic acid and 6-mercaptopurine are historically very well-known therapeutic agents with low toxicity profiles. The rationale for this study is that the combination of these drugs with low toxicity will be well tolerated in elderly AML patients with comorbidities, or lower performance status. This combination could have a beneficial therapeutic effect on overall survival and contribute to a better quality of life.
