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.
Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disorder characterized by the destruction of red blood cells through warm or cold antibodies. Glucocorticoid (combined with rituximab) is the first-line treatment. However, the recurrence rate is very high and some patients may not respond to steroids. Second-line therapies include cyclosporine A (CsA), cyclophosphamide, rituximab, azathioprine, and even splenectomy. Our previous study of sirolimus in refractory/relapsed AIHA and ES found an effective rate of 80%. Therefore, the investigators plan to explore the efficacy and safety of sirolimus in the treatment of refractory/relapsed wAIHA.
This is a prospective, single-arm, phase Ib/II trial . The objective of this study is to evaluate the efficacy and safety of adebrelimab, camrelizumab plus apatinib as first-line therapy in patients with advanced hepatocellular carcinoma
Oral and maxillofacial region is an important anatomical part of human body, responsible for chewing, swallowing, language, expression, breathing and other physiological functions. The tissue defects in this area not only seriously affect the physiological function, but also lead to facial deformity and aesthetic damage, affecting the quality of life of patients. The anterolateral thigh flap has become one of the main methods for defect repair due to its large tissue volume and high survival rate, and one of the key steps to ensure a high survival rate is the location of the perforator. How to find the perforator more accurately by improving the detection scheme or locating the perforator according to the anatomical structure, and guide the preparation and cutting of the flap, is the main direction of current research. This study intends to conduct a prospective diagnostic phase II clinical study on perforator localization of flap perforator, and explore its effectiveness and accuracy through sensitivity and specificity. In this study, a total of 76 patients with maxillofacial defects caused by tumors, trauma and other reasons requiring anterolateral femoral flap repair were included, and the perforator branch of femoral anterolateral flap was positioned preoperatively by means of perforator positioning device and color Doppler ultrasound. After the anterolateral thigh flap was prepared, the incision was closed in the donor area of the leg, and the flap was transplanted free to the maxillofacial defect area for repair. The sensitivity, specificity, positive predictive value, negative predictive value, distance difference and odds ratio of the two methods were calculated respectively, and the differences of each evaluation index between the two groups were compared, mainly to evaluate the sensitivity and specificity between the two groups.
This phase II study is designed to investigate the efficacy and safety of BL-B01D1 monotherapy, SI-B003 monotherapy, and BL-B01D1+SI-B003 combination therapy in patients with extensive-stage small cell lung cancer.
Ia: To observe the safety and tolerability of BL-M11D1 in patients with relapsed/refractory acute myeloid leukemia to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of BL-M11D1. Ib: Further observe the safety and tolerability of BL-M11D1 at the recommended dose in phase Ia to determine the recommended dose in phase II clinical study (RP2D).
The primary objective:To evaluate the efficacy of different administration protocols of human dental pulp mesenchymal stem cells for the treatment of chronic periodontitis patients. The secondary objective:To evaluate the safety of different administration protocols of human dental pulp mesenchymal stem cells for the treatment of chronic periodontitis patients. The exploratory objective:To investigate the effects of human dental pulp mesenchymal stem cells on biomarkers in gingival crevicular fluid in chronic periodontitis patients.
1. On the basis of previous studies, standardized randomized controlled clinical trials were conducted to observe the efficacy and safety of acupuncture in the treatment of mild cognitive impairment after stroke using the international rating scale, and the clinical experience was transformed into evidence. 2. According to the clinical outcomes reported by patients, the differences between Chinese and western scales in evaluating mild cognitive impairment after stroke were compared. On the basis of "disease differentiation, syndrome differentiation and meridian differentiation", the syndrome differentiation and treatment system of mild cognitive impairment after stroke was preliminarily constructed, and the TCM syndrome prediction model was improved.
This is a single-center, open-label, phase 2 study to evaluate the efficacy and safety of target therapy for patients with relapsed/metastastic salivary gland carcinoma based on molecular typing.
The goal of this clinical trial is to test the cooling effect of cooling blanket in patients with heat stroke. The main questions it aims to answer are: - the cooling rate of cooling blanket in patients with heat stroke - the relationship between cooling blanket and outcomes in patients with heat stroke Participants will accept the cooling blanket or non-cooling blanket according to the randomization group. Researchers will compare cooling rate and outcomes to see if the cooling blanket can accelerate the cooling speed and improve the prognosis of patients in heat stroke.
This is a randomized double-blind controlled exploratory clinical study to evaluate the efficacy and safety of FB1006 in the treatment of amyotrophic lateral sclerosis (ALS) patients.
