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.
Post-stroke cognitive impairment (PSCI) refers to a clinical syndrome characterized by cognitive impairment that occurs after a stroke event and persists for at least 24 weeks. Due to the early recovery of conditions such as delirium and transient cognitive impairment after stroke, the diagnosis of PSCI often requires cognitive assessment at 12 to 24 weeks post-stroke to determine the severity of cognitive impairment. It can be classified according to the severity of cognitive impairment as post-stroke cognitive impairment no dementia (PSCIND) and post-stroke dementia (PSD). Recent large international cohort studies have reported an incidence rate of PSCI ranging from 24% to 53.4%, and patients with PSCI have a significantly higher mortality rate compared to those without cognitive impairment. Guidelines such as American Heart Association/American Society of Anesthesiologists (AHA/ASA) and the Chinese "Expert Consensus on the Management of Post-Stroke Cognitive Impairment" propose integrating cognitive impairment and stroke intervention strategies. Early comprehensive intervention and treatment for high-risk individuals after stroke, aiming to delay or prevent the progression from PSCIND to PSD, are the primary goals in the current treatment of PSCI. However, there is currently a lack of large randomized controlled trials (RCTs) for PSCI, and research is still needed to determine whether cognitive-enhancing drugs can reduce the risk of PSCI occurrence and improve outcomes and prognosis for PSCI patients. A randomized, double-blind, multicenter clinical study involving 281 non-dementia vascular cognitive impairment (VCI) patients showed that the overall cognitive scores of patients treated with donepezil for 24 weeks significantly improved compared to the placebo group. The aim of this study is to evaluate the effectiveness of donepezil in the treatment of post-stroke cognitive impairment. It will be a multicenter, randomized, double-blind, placebo-controlled trial with a 48-week treatment duration. The study will observe the difference in PSCI incidence rate between the donepezil treatment group and the conventional stroke treatment group at 24 weeks and evaluate the improvement in post-stroke cognitive impairment after 6 months of donepezil treatment compared to conventional treatment. This study will be conducted in two stages: the first stage (0-24 weeks) aims to assess whether donepezil can reduce the risk of PSCI occurrence and will be a multicenter, randomized, double-blind, placebo-controlled study. The second stage (24-48 weeks) aims to evaluate whether donepezil can improve the prognosis of PSCI patients and will also be a multicenter, randomized, double-blind, placebo-controlled study.
To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.

This is a prospective, single-center, single-arm, phase 2 study. The aim of this study is to evaluate the efficacy and safety of Anti-lymphocyte globulin plus eltrombopag in combination with moderate-dose cyclophosphamide for severe aplastic anemia.
This study is a multicenter, single arm, open, non-randomized, dose-escalation/ expansion phase Ib/II clinical study. The dose-escalation part of phase Ib clinical trial was conducted according to the Bayesian Optimal Interval Design (BOIN), with a total of three dose groups: low, medium, and high. Dose level 1: Selinexor 40mg PO QW, Olaparib 150mg PO BID; Dose level 2: Selinexor 60mg PO QW, Olaparib 150mg PO BID; Dose level 3: Selinexor 80mg PO QW, Olaparib 150mg PO BID. The number of patients in each group is 3, with a maximum sample size of 9, to evaluate the safety and effectiveness of the medication, and to provide a basis for recommended phase II dose (RP2D). Eligible subjects received medication on the first day and then entered a 21 day observation period of dose-limiting toxicity (DLT). DLT is defined as the occurrence of level 3 non hematological toxicity or level 4 hematological toxicity. Evaluate the efficacy every 6 weeks. In this study, an independent Data Safety Monitoring Committee (DSMC) and an Independent Review Committee (IRC) were established to regularly review the safety and effectiveness data of each research center, with the aim of protecting subjects safety, ensuring the reliability of clinical trials and the objectivity of trial results.
The purpose of this study is to find out whether treatment with Serplulimab combined with Trastuzumab and Chemotherapy will improve the survival of gastric cancer patients with stage II-III after surgery.
To examine the effects of a 1-year cluster-randomized controlled intervention of MIND diet on cognitive function among 240 participants with mild cognitive function (MCI) aged 50 years and above from 4 communities.
This is an open, single-arm, multi-center clinical study designed to evaluate the efficacy and safety of TQB2618 injection combined with penpulimab injection and Anlotinib Hydrochloride Capsules in patients with advanced HCC.
Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSICH patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Study Design: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Objective: In this study, investigators will estimate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.
The goal of this Phase 2 trial is to evaluate a non-surgical bladder-preserving treatment mode which consists of induction chemotherapy plus anti-programmed cell death protein 1 (anti-PD-1) therapy followed by radiotherapy plus concurrent anti-PD-1 therapy. The main questions it aims to answer are: (i) whether the anti-PD-1 antibody, toripalimab, is effective in treating muscle-invasive bladder cancer (MIBC), when combined with chemoradiation; (ii) whether toripalimab is safe in combination with chemoradiation. Participants will receive 3 cycles of induction treatment containing chemotherapy with gemcitabine and cisplatin/carboplatin, plus toripalimab. Then the ones without progressive disease will receive radical radiotherapy plus 2 cycles of concurrent toripalimab.
