Filter by:Romiplostim has been used in clinical trials for the treatment of severe and very severe aplastic anemia (SAA/vSAA) in Asian participants who are either previously untreated with immunosuppressive therapy (IST) or refractory to IST. This study will evaluate the efficacy of romiplostim in the treatment of participants with SAA/vSAA. The primary objectives of this study are to: Arm 1: Evaluate the efficacy of romiplostim and IST in adult SAA/vSAA participants who are previously untreated with IST (1L) Arm 2: Evaluate the efficacy of romiplostim treatment in adult SAA/vSAA participants who are refractory to IST (2L+)
Allogeneic haematopoietic stem cell transplantation (aHSCT) is the only curative treatment for many paediatric and young adult haematological pathologies (acute leukaemia, myelodysplastic syndromes haemoglobinopathies, bone narrow aplasia, severe combined immunodeficiency). Despite the major therapeutic progress made over the last 50 years, particularly in terms of supportive care, post-transplant morbidity and mortality remain high. Infectious complications, whose incidence varies between 30 and 60%, are the first cause of mortality in the immediate post-transplant period. In order to protect the patient from the occurence of severe infectious episodes, aHSCT must be performed in a highly protected environment (positive pressure chambers). This has consequences for the experience and impact of hospitalization on the patient and family. This is particularly true in pediatrics, with children, adolescents or young adults, where it is not only the patient's quality of life that is at stake, but also his emotional and psychomotor development. In this specific population, prolonged hospitalization (at least 6 weeks) in a sterile room will be responsible for physical deconditioning accompanied by a decrease in muscle mass. Patients often experience an deteriorated quality of life. Today, the benefits of physical activity (PA) during and after cancer treatment have been widely demonstrated. The objective of the study is to assess the feasibility of an adapted physical activity program during the isolation phase for achieving aHSCT in children, adolescents and young adults. This is a prospective, interventional, monocentric cohort study conducted at the institute of Paediatric Haematology and Oncology in Lyon. The intervention will take place during the isolation phase and will be based on an adapted physical activity (APA) program defined at inclusion, integrating supervised sessions with an APA teacher, as well as autonomous sessions performed by means of a connected bike in the sterile room. The program will be individualized according to age, aerobic capacities, and PA preferences. Sessions will also be tailored to the biological, psychological, and social parameters of patients. The total duration of the intervention is 3 months. To date, no PA studies have been performed in patients under 21 years old requiring aHSCT during the sterile isolation phase. EVAADE will therefore be the first study in this population to offer an innovative procedure with a connected device.
Patients with medical conditions requiring allogeneic hematopoietic cell transplantation (allo-HCT) are at risk of developing a condition called graft versus host disease (GvHD) which carries a high morbidity and mortality. This is a phase I/II study that will test the safety and efficacy of hematopoietic cell transplantation (HCT) with ex-vivo T cell receptor Alpha/Beta+ and CD19 depletion to treat patients' underlying condition. This process is expected to substantially decrease the risk of GvHD thus allowing for the elimination of immunosuppressive therapy post-transplant. The study will use blood stem/progenitor cells collected from the peripheral blood of parent or other half-matched (haploidentical) family member donor. The procedure will be performed using CliniMACS® TCRα/β-Biotin System which is considered investigational.
This will be a randomized, placebo-controlled trial with a 2x2 factorial design testing the effects of an NAD+ precursor (NR) and exercise on skeletal muscle quality and VO2max in AYA HCT survivors. The primary outcome is the change in muscle strength (isometric knee extension) from baseline to 16 weeks. Key secondary outcomes are the change in muscle strength (ankle plantarflexion) from baseline to 16 weeks, the change in grip strength from baseline to 16 weeks, the change in lower extremity muscle mass from baseline to 16 weeks, the change in muscle OXPHOS capacity from baseline to 16 weeks, and the change in aerobic capacity (VO2 max) from baseline to 16 weeks.
Outcomes for patients with severe aplastic anemia (SAA) who are refractory to first-line immunosuppressive therapy (IST) and who lack a matched unrelated donor (MUD) remain poor. Recently, the use of eltrombopag (ELT) has shown blood count improvements in 40% of these patients. However, most refractory patients do not respond to ELT or other second-line treatment and are therefore exposed to life-threatening infections, and bleeding. During the past 2 decades, there has been a significant decrease in infection-related mortality in patients with SAA unresponsive to initial IST but clonal evolution including paroxysmal nocturnal hemoglobinuria (PNH), myelodysplastic syndrome (MDS), and acute myeloid leukemia (AML) still occur in the long-term with a grim prognosis. Overall, the overall survival of such patients with acquired refractory SAA to ELT is about 60-70% at 2 years. Hematopoietic stem cell transplantation (HSCT) using alternative donor sources (i.e., mismatched unrelated donors, cord blood (CBT), and haplo-identical family donors) may be curative in patients with refractory SAA, despite carrying much higher rates of complications than in transplantations from matched related or unrelated donors. Recently, our group showed that CBT is a valuable curative option for young adults with refractory SAA. However, not all patients have available CB and CBT treatment related mortality is high in adult patients. Haploidentical (haplo) related donor Stem Cell Transplantation (haplo-SCT) have improved dramatically outcomes using T-cell replete grafts with administration of post-transplantation cyclophosphamide (PTCy). Preliminary results in a little number of patients with refractory SAA at Kings college (London, UK) and John Hopkins (Baltimore, USA) seem promising. The investigators retrospectively analyzed data from 36 patients (median age 42 years) transplanted between 2010 and 2017 in Europe on behalf of the SAA working party of the European Blood and Marrow Transplantation group. The 1-year overall survival was about 80% suggesting that this approach might be a valid option in this particular poor clinical situation. The main objective of this study is to demonstrate a benefit in term of the 2-year overall survival rate from 60% (historical rates in patients with acquired refractory idiopathic aplastic anemia) up to 80% using haplo-SCT with PTCy.
This study consists of two parts. Part 1 is a pilot BE study, and Part 2 is a pivotal study to demonstrate the bioequivalence of test and reference formulation, both of which adopt a single-center, randomized, open-label, three-period crossover design.
This is a single-dose, open-label, phase I clinical study evaluating the PK of hetrombopag in subjects with mild hepatic impairment (Child-Pugh Class A), subjects with moderate hepatic impairment (Child-Pugh Class B), as well as age-, weight-, and gender-matched subjects with normal hepatic function.
This is a single-center, single-arm, open-label, self-controlled, phase I clinical study. A total of 26 male or female healthy subjects are intended to be enrolled to evaluate the PK drug-drug interaction between ciclosporin and hetrombopag.
After exiting the RACE trial (NCT02099747) patients will be invited to participate in this long term follow-up study
This phase II clinical trial evaluates whether a modified modality of conditioning reduces treatment-related mortality (TRM) in patients who undergo a hematopoietic stem cell transplant (HSCT) for a hematological malignancy. HSCT is a curative therapy for many hematopoietic malignancies, however this regimen results in higher rates of TRM than other forms of treatment. In recent years, less intense conditioning regimens with radiation and chemotherapy prior to HSCT have been developed. Radiation therapy uses high energy sources to kill cancer cells and shrink tumors while chemotherapy drugs like fludarabine and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This study evaluates whether a two-step approach with lower-intensity regimens of these treatments prior to HSCT reduces the rate of TRM.
