There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
About 33% of patients with myeloid or lymphoid malignancies experience relapse with HLA loss after haplo-HSCT. Due to the specificity of HLA-loss relapse, the 2019 European Society for Blood and Marrow Transplantation (EBMT) pointed out that for diagnosed HLA-loss patients, it is recommended to use different HLA-haploidentical donors, and lymphocyte infusions from the original donor cannot improve the prognosis. Clinical studies have found that second transplantation can achieve prolonged disease-free survival than chemotherapy for patients with HLA loss, and it may be an effective treatment strategy for these patients. However, due to the high standard of second hematopoietic stem cell transplantation (HSCT), not all patients can find suitable donors. Since the first successful application of umbilical cord blood transplantation (UCBT) by Gluckman et al. in France in 1988 for the treatment of Fanconi anemia, umbilical cord blood (UCB) has been widely used as a reliable source for HSCT in the treatment of hematological diseases. In 1998, Professor Yongping Song led the first successful UCBT in the treatment of leukemia, opening up the path of it in China. Compared with peripheral blood stem cell transplantation (PBST), UCBT has a higher engraftment rate. UCB contains more primitive and purer stem cells than bone marrow hematopoietic stem cells. UCBT can be performed with only 4 HLA matches, and the degree of rejection, the risk of disease relapse, and the incidence of chronic graft-versus-host disease (cGVHD) are all relatively low, greatly improving the survival of patients. Although UCBT has been a potential treatment for second transplantation, the effective conditioning regimen is still under discussion. Improving the incidence of engraftment , the tolerance of conditioning, and reducing transplant-related mortality (TRM) are issues of great concern in second transplantation. A standard RIC regimen composed of fludarabine (200mg/m2) combined with cyclophosphamide (50mg/kg) and 2Gy or 3Gy total body irradiation (TBI) is the most common conditioning regimen used in UCBT. Although the tolerance of this RIC is acceptable, the relapse rate after transplantation is relatively high, and the implantation failure rate is also high in high-risk populations. The inclusion of thiotepa (10mg/kg) combined with fludarabine, cyclophosphamide, and 4Gy TBI in an intensified version of the RIC regimen has improved the engraftment rate without increasing TRM. In addition, studies have also confirmed that increasing the dose of TBI can improve engraftment in transplant recipients at high risk of UCBT failure. The fludarabine/busulfan/melphalan (Flu/Bu/Mel) conditioning regimen was first used for salvaging UCBT in unresponsive hematological malignancies in 2016 and achieved good clinical outcomes. Subsequently, several transplant centers in Japan adopted the Flu/Bu/Mel conditioning regimen for UCBT and confirmed that, compared with the Flu/Bu4 regimen, it not only improved overall survival (OS) but also reduced disease relapse rate without increasing TRM. A recent multicenter retrospective study of UCBT in patients with acute myeloid leukemia in remission found that compared with the TBI/Cy conditioning regimen, the Flu/Bu/Mel conditioning regimen improved the engraftment rate and exerted the GVL effect, reducing NRM and improving OS. Based on the above, TBI/Flu/Bu/Mel as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT is safe and feasible, and is expected to improve the prognosis of these patients. Therefore, based on existing clinical experience with research evidence, our center plans to conduct a clinical study of low-dose TBI and FBM as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT, observing the improvement in the cumulative incidence of engraftment, disease relapse, GVHD, and survival rate in patients who received this regimen.
The main objective is to evaluate the effectiveness of telitacicept in pediatric patients with frequently relapsing or steroid dependent nephrotic syndrome within the 52-week follow-up.
The goal of this clinical trial is to evaluate the efficacy and safety of Sufenidone (SC1011) in patients with IPF, and to provide a new safe and effective treatment option for patients with IPF. Participants will complete the study including screening period, treating period, and follow-up period. Investigators will compare the annual rate of decline in FVC to see if it is an optional new drug. The participants have lung function tests at study visits. The results of the lung function tests are compared between the SC1011 groups and the placebo group. The doctors also regularly check the general health of the participants.
Conduct a retrospective and prospective study to confirm the association between blood cells counts and the efficacy and safety in immunochemotherapy in patients with advanced esophageal cancer.
The goal of this observational study is to explore the value of Humanin for early diagnosis and short-term prognosis of AKI patients after heart transplantation. The main question it aims to answer are:whether Humanin can be a novel marker for predicting AKI after heart transplantation Researchers will compare the Humanin concentration in patients with AKI did not occur after heart transplantation to see if Humanin can be a novel marker for predicting AKI after heart transplantation
This study is designed to observe the treatment options in real-world clinical practice as well as the safety and efficacy of different treatment strategies.
This study is based on the risk factors of previous studies to formulate a bundle treatment plan to prevent ventilator dependence in children, in order to reduce the proportion of ventilator dependence in children and provide a theoretical basis for reasonable intervention of children with mechanical ventilation. Participants will receive intensive rehabilitation, nutrition, and tracheotomy at different time periods. Researchers will compare the control group to see whether it can reduce the incidence of ventilator dependence
