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.
This clinical trial aims to evaluate the safety and effectiveness of umbilical cord mesenchymal stem cell (UCMSC)-derived extracellular vesicle nebulization inhalation therapy for the treatment of chronic cough after COVID-19 infection. The main objective is to assess whether UCMSC-derived exosome nebulization inhalation therapy alleviates chronic cough after COVID-19. Participants will be asked to complete a questionnaire to help researchers evaluate their cough severity and to record their scores before nebulization inhalation of UCMSC-derived exosomes. Participants will receive either continuous nebulized inhalation of UCMSC-derived exosomes for 5 days, twice daily, or no treatment. Researchers will compare the experimental and control groups to evaluate the safety and efficacy of UCMSC-derived exosomes for the treatment of chronic cough after COVID-19 infection.
The study is being conducted to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HRS-5635 in healthy adults and chronic hepatitis B. To explore the reasonable dosage of HRS-5635.
In endoscopic spinal nerve root decompression surgery, the intraoperative nerve exploration is time-consuming and critical. According to statistics, the incidence of nerve root injury under spinal endoscope is 1.8-2.5%. Damage to nerve roots may lead to postoperative sensory retardation and motor weakness, thereby impairing the physical function of patients. A real-time auxiliary intraoperative nerve identification technology is necessary. In this prospective, open-label, randomized, parallel controlled trial, 40 patients who undergo endoscopic spinal surgery are included. Subjects are randomly divided into control group and low, medium and high Indocyanine green(ICG) preoperative administration experimental group. Standard endoscopic spinal surgery is performed in the control group. Patients in the experimental group received an intravenous injection of ICG before surgery, and a standard endoscopic spinal surgery is performed with the use of a fluoroscopic endoscopic surgical imaging system to assist the surgeon in identifying and protecting the nerve roots. The main objectives of this experiment are (i) to explore the safety and feasibility of ICG fluorescence imaging to assist in nerve root identification during endoscopic spinal surgery and (ii) the effectiveness of this technique for endoscopic search for nerve roots. The secondary objective is to explore the optimal ICG dosing regimen.
To evaluate the efficacy and safety of umbilical cord blood mononuclear cells in the treatment of chronic atrophic gastritis.
Prospective phase II clinical study aim to explore the clinical outcome of patients with unresectable locally recurrent rectal cancer (LRRC) treated with re-irradiation by carbon ion radiotherapy (CIRT)
A multicenter, single-arm, open study to evaluate the safety and efficacy of Serplulimab in combination with bevacizumab and first-line chemotherapy in driver negative non-squamous NSCLC patients with brain metastases
The goal of this single-arm phase II study is to test in patients with non-remission myeloid malignancies undergoing allogeneic hemopoietic stem-cell transplantation (allo-HSCT). The main question it aims to answer are: - The safety and efficacy of fractionated busulfan Combined With Chidamide/Fludarabine/Cytarabine(ChiFAB) conditioning regimen in increasing the overall survival rate in patients with non-remission myeloid malignancies after allo-HSCT. - The efficacy of fractionated busulfan conditioning regimen in reducing the recurrence rate in patients with non-remission myeloid malignancies after allo-HSCT. Participants will receive fractionated busulfan-based ChiFAB conditioning regimen (busulfan 3.2mg/kg d-13, -12, 1.6mg/kg d-6~-3, fludarabine 35mg/m2 d-6~-2, cytarabine 1g/m2,d-6~-2, chidamide 30mg d-13,-10,-6,-3) before allo-HSCT.
Prediction for pCR After Neoadjuvant Immunotherapy Combined With Chemotherapy Using Single-Cell RNA Sequencing in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma
This study aims to assess the therapeutic efficacy and safety of venetoclax in combination with azacitidine and CAG as induction regimen in Patients with Refreactory/Relapse Acute Myeloid Leukemia.
The objective of this clinical trial was to compare the effects of different interventions on the recovery of stroke patients. The main question it aims to answer are: whether the intervention mode of integrated Chinese and western medicine is more valuable to implement. Researchers randomly assigned 90 patients to either group A or Group B, 45 in each group. Group A adopted the conventional three-level rehabilitation model; Group B adopted the three-level network rehabilitation model under the medical alliance for rehabilitation treatment with combination of Chinese and Western medicine. Fugl-Meyer motor score was used to assess the patient's motor ability, Berg balance scale was used to assess the patient's balance ability, National Institute of Health stroke scale was used to assess the patient's neurological function, and modified Barthel index was used to assess the patient's ability of daily living.
