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.
Idiopathic macular hole (IMH) is a fundus disease without clear etiology, most often seen in healthy women over 50 years of age, and is often associated with ocular manifestations such as loss of central vision and visual distortion. It is often associated with loss of central vision, visual distortion, and other ocular manifestations. It is currently treated by vitrectomy combined with internal limiting membranes (ILM) peeling followed by gas filling. A strict prone position for a certain period of time after surgery has a positive effect on the healing of the macular fissure. The need for a strict prone position after IMH has been demonstrated in previous studies (especially when the IMH diameter is >400 μm). However, due to the anti-human mechanics of the face-down position, patient comfort, sleep quality and quality of life are greatly compromised. Therefore, this study designed a smart head position monitoring device to assist patients in maintaining the correct position and recording the effective position time. The study was conducted to determine the shortest prone position time based on macular fissure closure, to minimize the adverse effects of postoperative position, and to obtain the maximum recovery of visual acuity and visual field.
Study design: Prospective, single-arm, single-center phase II clinical study; Primary endpoint: Objective response rate via investigator, Safety; Secondary endpoints: disease control rate, disease-free survival, overall survival, and proportion of acceptable radical resection of primary lesions; Main characteristics of enrolled patients: Patients with initially unresectable gallbladder cancer; Interventions: Combination of Gemcitabine, Nab-paclitaxel, Sintilimab and Bevacizumab; Sample size: Using Simon's two-stage design, 15 patients in the first stage, and if more than 4pts response, enlarge the sample size to 45 patients in total; Treatment until: 1. successfully conversed to resectable disease 2. progressed disease 3. intolerable toxicity 4. patient requests withdrawal; Research process: In this study, patients who met the inclusion criteria were evaluated at the end of every 9 weeks of treatment, up to surgical treatment or disease progression; Safety evaluation: Evaluate adverse reactions according to CTCAE 5.0; Follow up: every 90 days (±7 days) until the subject died, lost follow-up or the end of the study.
This is a non-randomized, open label, single-site, single-dose, phase 1 study in up to 5 participants (between 5 and 35 years of age, inclusive) with Transfusion-dependent α-thalassemia. The study will evaluate the safety and efficacy of autologous hematopoietic stem cell transplantation (HSCT) using GMCN-508A Drug Product [autologous CD34+ hematopoietic stem cells transduced with GMCN-508A lentiviral vector encoding the human α-globin gene].
PM8002 is a bispecific antibody targeting PD-L1 and VEGF. This is a phase II/III study to evaluate the efficacy and safety of PM8002 in combination with pemetrexed and carboplatin in patients with EGFR-mutant locally advanced or metastatic non-squamous NSCLC who have failed to EGFR-TKI treatment.
To study the efficacy of myopi control with two methods: low lever red light and peripheral defocus spectacles with four groups and design with prospective, double-blind, randimized, and with control for 6 month.
The goal of this randomized, double-blind, cross-over inverventional study is to evaluate the efficacy of white kidney bean on OGTT (oral glucose tolerance test). About 34 eligible participants will be randomized in two groups of the same size to take the assigned interventions at one study site in Shanghai, two visits will be required. The first group of participants will take Wonderlab product first and then placebo product after 72 hours of washout period, while the other group of of participants will take placebo product first and then Wonderlab product after 72 hours of washout period. For each visit, the finger blood will be sampled and the relevent data such as blood glucose will be captured based on OGTT procedures, and recorded into clinical data management system for statistical analysis. Researchers will compare the two groups to see if there is significant change of blood glucose by using products containing ingredient of white kidney beans.
Local used high molecular weight Hyaluronan (HA) with high viscosity has a variety of receptors in the human body, including CD44, LYVE-1, RHAMM, HARE, Siglec-9, TLR2, CEMIP and TMEM2. Intra-articular local injection of HA has a certain degree of analgesic effect. Local injection of HA into the nerve trunk directed by ultrasound was used for the treatment of neuropathic pain. It was reported that the analgesic effect of HA is regulated by TRPV1 ion channels. This study hypothesizes that hyaluronidase cleaves HA to generate low molecular weight HA fragments HA35 with good tissue permeability, which may bind to a variety of HA receptors on the cell surface within the tissues and produce a broad-spectrum analgesic effect. In this study, 35kDa Hyaluronan fragment HA35 was prepared by mixing hyaluronidase PH20 injection and high molecular weight Hyaluronan (HA) injection at room temperature for 20 minutes. In this study, hyaluronidase injection and Hyaluronan injection were off-label used to conduct an investigator-initiated study (IIT or IIS) for the treatment of herpes zoster and shoulder, neck, back and temporal pain.
This is an open single-arm clinical study aimed at evaluating the safety and tolerance of allogeneic γ9δ2 T cell injection in the treatment of patients with recurrent hematologic tumors after allogeneic hematopoietic stem cell transplantation.
To evaluate the CR rate of B-NHL subjects who achieved PR at intermediate assessment after first-line chemotherapy treated with autologous stem cell transplantation + Anti-CD19 CAR T cells.
The goal of this observational study is to explore the efficacy and safety of Tenofovir Amibufenamide (TMF) in Entecavir (ETV) treated chronic hepatitis B patients with low-level viraemia. The main question it aims to answer is: - The efficacy and safety of TMF in chronic hepatitis B patients with low-level viraemia. - What is the appropriate treatment for ETV treated chronic hepatitis B patients with low-level viraemia. Participants will choose to maintain their original regimen (ETV) or switch to TMF After being fully informed of the benefits and risks of treatment. Researchers will compare ETV and TMF to see if there is a difference in the efficacy of the two drugs in chronic hepatitis B patients with low-level viraemia.
