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.
A Phase II Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Azvudine in Preventing SARS-Cov-2 Infection in Household Contacts of Individuals Infected with SARS-CoV-2 in China
The goal of this randomized, controlled, open-labeled interventional clinical trial is to test the efficacy and safety of umbilical cord mesenchymal stem cells (UC-MSCs) in the treatment of severe and critical COVID-19 patients. The main questions it aims to answer are: 1. The efficacy of UC-MSCs in the treatment of severe and critical COVID-19 patients. 2. The safety of UC-MSCs in the treatment of severe and critical COVID-19 patients. 3. The potential immune mechanisms of UC-MSCs in the treatment of severe and critical COVID-19 patients. Participants will receive standard therapy, Paxlovid treatment or the UC-MSCs treatment. For the standard treatment, it will be conducted according the 9th edition of Chinese guidelines for COVID-19 infection. For UC-MSCs treatment, participants will be given UC-MSCs instillation at the first and fourth day after assignment. Blood examples will be taken at indicated time for arterial blood gas analysis and other tests. And participants should also objectively report their symptoms change and other information related to the treatment as listed the research protocol.
This study is a prospective cohort study aimed to clarify the continuous immune state changes of patients with COVID-19. Investigators include the patients admitted to the hospital within one week after the onset of COVID-19. 10ml of patients' blood was collected day 1, day 7, day 14 , and day 20 after the patients admitted to the hospital. The blood inflammatory factors, immune related molecules, and immune cells were detected to determine the changes of patients' immune status. The impact of immune status changes on prognosis and quality of life in later follow-up period was evaluated by various questionnaires and evaluation scales.
Majority of the existing studies on the high intensity training of referees are heart rate-based prescription. It is probably the most commonly measured physiological marker used to control or measure exercise intensity in the field.Indeed, speed-based intensity training is more acute than heart rate-based training on the intensity of physical work performed above v/pVO2max. This study the setting of exercise intensity reference the ending velocity of the 30-15 intermittent fitness test.
In recent years, the prognosis of pediatric relapsed ALL patients has improved, but the 5-year OS of patients with first recurrence is still less than 50%. A number of in vitro studies have shown that arsenic trioxide (ATO) can selectively inhibit the growth and induce apoptosis in a variety of leukemia cell lines, suggesting that ATO as a synergist combined with other common chemotherapy drugs may provide a new target for the treatment of relapsed ALL. Realgar Indigo naturalis formula is a compound traditional Chinese medicine preparation developed in China. The main component of realgar is arsenic tetrasulfide (As4S4), which can produce similar pharmacological effects to ATO. Based on the R3 protocol, this study plans to perform a double-blind randomized controlled trial, and to randomly combine compound Huangdai tablets with compound Huangdai tablets in the treatment of intermediate and high risk ALL children, in order to improve the MRD negative rate after induction therapy in this group of children, which may provide a new method for the clinical treatment of relapsed ALL.
To study the molecular pathogenesis of cataract and explore possible treatments，anterior lens capsules were collected from cataract patients
Evaluate the Safety, Tolerability and Pharmacodynamics of Intravenous Administration of SHR-1707 In Patients with Mild Cognitive Impairment Due to Alzheimer's Disease or Mild Alzheimer's Disease.
A Phase II study that evaluating the efficacy and safety of pembrolizumab in combination with chemotherapy as neoadjuvant therapy for triple-negative breast cancer in the Chinese population
Chimeric antigen receptor modified T (CAR-T) cell therapy still has multiple difficulties in solid tumors, such as absence of tumor specific antigens, complex immunosuppressive tumor microenvironment, and tumor heterogeneity. In this study, investigators developed a novel hypoxia-stimulated CAR expression system (HypoSti.CAR) that could enable CAR-T cell effectively expand and survive in hypoxic tumor microenvironment. After accomplishment of animal model verification, investigators conduct this clinical trial in order to assess the in vivo safety, feasibility and efficacy of HypoSti.CAR-HER2 T cells in HER2 antigen positive advanced solid tumors.
ARGX-113-2010 is an open-label extension study with the aim to provide supporting evidence that efgartigimod PH20 SC is a safe and effective long-term treatment for bullous pemphigoid (BP), providing symptom control and eventually remission, while also reducing the cumulative exposure to oral corticosteroids (OCS). All participants who complete the end-of-treatment period (EoTP) visit at week 36 in ARGX-113-2009 will be invited to enroll. In ARGX-113-2009, participants received efgartigimod PH20 SC or placebo with concurrent OCS, or rescue therapy (without efgartigimod PH20 SC or placebo). Depending on their clinical status at the time of rollover into ARGX-113-2010, participants may stop, continue or initiate efgartigimod PH20 SC treatment. In ARGX-113-2010, participants will stop efgartigimod PH20 SC treatment when they achieve complete remission (CR) or partial remission (PR) while being off other concurrent BP therapy for at least 8 weeks. Participants not in CR or PR while off OCS for ≥8 weeks and not on rescue therapy will either start or continue efgartigimod PH20 SC treatment, while maintaining the treatment allocation of ARGX-113-2009 blinded. Participants may also be retreated with efgartigimod PH20 SC after a relapse. In this study, loading doses of 2000 mg (on day 1 and day 8 of a treatment course) and weekly maintenance doses of 1000 mg will be used.
