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.
Despite major advances in the field of psychopharmacology in recent years, the majority of treated schizophrenia patients retain disabling symptoms, most commonly a variety of negative symptoms. Currently, clinical treatment of schizophrenia remains dominated by pharmacological control. The current use of antipsychotic medications is effective in controlling the positive symptoms of schizophrenia, but has little effect on the negative symptoms. Neuroimaging and neurophysiological studies have shown that negative symptoms are associated with abnormal brain activity in the combined right and left dorsolateral prefrontal and temporoparietal joint regions, and that physical therapy techniques can modulate cortical activity. Therefore, this study aims to investigate the efficacy of transcranial direct current stimulation(tDCS) combined with repetitive transcranial magnetic stimulation(rTMS) on negative symptoms in patients with schizophrenia and to explore possible mechanisms. The double-blind randomized placebo-controlled study comparing active tDCS stimulation combined with active rTMS stimulation, active rTMS stimulation combined with sham tDCS stimulation, and active tDCS stimulation combined with sham rTMS stimulation to sham tDCS stimulation combined with sham rTMS stimulation at 4 weeks of treatment and 2 weeks of follow-up in patients with predominantly negative symptoms with schizophrenia was studied for efficacy. In addition to the primary observation of changes in the Negative Symptom Assessment Scale (SANS), secondary outcomes include changes in Positive and Negative symptom scale (PANSS) total and negative total scores, changes in the MATRICS Consensus Cognitive Battery (MCCB), changes in local brain activity (functional magnetic resonance imaging, fMRI), white matter integrity (diffusion tensor imaging, DTI), changes in laboratory examination indices changes and changes in psycho-behavioral and EEG index. This is the first clinical trial combining tDCS with rTMS for the treatment of schizophrenia patients with predominantly negative symptoms. This study will provide solid evidence for the combination of tDCS with rTMS for the treatment of negative symptoms in schizophrenia. This study will also help to further explore the mechanisms of tDCS combined with rTMS for the treatment of negative symptoms in schizophrenia in terms of imaging and behavior.
Optical Coherence Tomography （OCT）is a novel, non-invasive, high resolution special optical imaging techniques. In airway, Measure airway area and airway wall thickness is the most usage of Endobronchial Optical Coherence Tomography (EB-OCT）. Recently, the new protocol of EB-OCT is used to measure airway compliance, We will establish a new methodology of EB-OCT for measuring airway compliance, which will provide a new means to study respiratory diseases.
A Multicenter, Prospective, Observational Clinical Protocol for Chidamide in Combination With Rituximab and Lenalidomide (cR2) in Real-world Practice in Patients With Relapsed/Refractory Diffuse Large B-cell Lymphoma
Elevated aldosterone causes moderate to severe increase in blood pressure, and leads to various target organ damage including cardiovascular ones. Aldosterone has been considered one of the important risk factors for cardiovascular and cerebrovascular diseases. Currently, the use of mineralocorticoid receptor antagonists(MRA) has been proven to reduce blood pressure levels, but long-term prognostic data are lacking in hypertensive patients. Therefore, the purpose of this clinical trial is to assess the effect of MRA on cardiovascular disease in patients with Hypertension and Hyperaldosteronemia.
This study is a single arm, open, multi center phase II exploratory study. To evaluate the efficacy and safety of AK105 combined with androtinib hydrochloride capsule in patients with relapsed/refractory classical Hodgkin's lymphoma (relapse or progression after autologous stem cell transplantation, or relapse progression after autologous stem cell transplantation but ≥ 1 line systemic multi drug combination chemotherapy). After screening, the subjects met the inclusion criteria and did not meet the exclusion criteria, and then entered the treatment period. They received AK105 injection (once every three weeks, 200mg/time, intravenous infusion) combined with androtinib hydrochloride capsule (once a day, 10mg each time, and stopped for one week for two consecutive weeks). Every 21 days was a treatment cycle until disease progression/intolerance occurred or the sponsor terminated the study. Patients with complete remission (CR) continue to receive 4 cycles of treatment, and then further consolidate treatment every 9 weeks within 1 year of continuous CR, and can stop treatment after 1 year of continuous CR. At the end of the trial, the subjects who can still benefit from the study treatment as judged by the investigator will continue to be provided with the trial drug. The longest administration time of AK105 combined with androtinib hydrochloride capsules shall not exceed 2 years.
The research focuses on establishing a system for validating the effectiveness of key technologies for targeted combined non-invasive interventions in awakening consciousness.
This study is an open label, multicenter study. Subjects are randomized at a 1:1 ratio to receive either (arm A) azacitidine administered IH at day 1-5 and chidamide admistered twice a week for two weeks in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or (arm B) CHOP administered every 3 weeks for 6 cycles in patients with previously untreated peripheral T-cell lymphoma.
This trial uses prospective, retrospective, observational, non-blinded, multi-center, single-arm, post-marketing hospital data collection and research methods. The goal of this study is to assess the safety of BIOTRONIK Orsiro Sirolimus-Eluting Coronary Stent System in the Chinese patient population after marketing in China.
The purpose of the study was to evaluate the safety and efficacy of a branched type intraoperative stent system for the treatment of Stanford type A aortic dissection
Cytomegalovirus (CMV) remains a significant cause of morbidity and mortality after hematopoietic stem cell transplantation (HSCT). The course and outcome of CMV infection are different clinically, and the mechanism of CMV infection after transplantation has not been clarified. Reconstitution of cellular immunity after HSCT is a critical determinant of the control of CMV infection. Investigators will dynamically monitor the CMV-specific cellular immune reconstitution after HSCT，and analyze the clinical factors and therapy strategies affecting recovery of CMV-specific immunity during 1 year after HSCT.
