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.
Researchers are looking for a better way to prevent an ischemic stroke which occurs when a blood clot travelled to the brain in people who within the last 72 hours had: - an acute stroke due to a blood clot that formed outside the heart (acute non-cardioembolic ischemic stroke), or - TIA/mini-stroke with a high risk of turning into a stroke (high-risk transient ischemic attack), and who are planned to receive standard of care therapy. Acute ischemic strokes or TIA/mini-stroke result from a blocked or reduced blood flow to a part of the brain. They are caused by blood clots that travel to the brain and block the vessels that supply it. If these blood clots form elsewhere than in the heart, the stroke is called non-cardioembolic. People who already had a non-cardioembolic stroke are more likely to have another stroke. This is why they are treated preventively with an antiplatelet therapy, the current standard of care. Antiplatelet medicines prevent platelets, components of blood clotting, from clumping together. Anticoagulants are another type of medicine that prevents blood clots from forming by interfering with a process known as coagulation (or blood clotting). The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care without increasing the risk of bleeding. The main purpose of this study is to learn whether asundexian works better than placebo at reducing ischemic strokes in participants who recently had a non-cardioembolic ischemic stroke or TIA/mini-stroke when given in addition to standard antiplatelet therapy. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Another aim is to compare the occurrence of major bleeding events during the study between the asundexian and the placebo group. Major bleedings have a serious or even life-threatening impact on a person's health. Dependent on the treatment group, the participants will either take asundexian or placebo once a day for at least 3 months up to 31 months. Approximately every 3 months during the treatment period, either a phone call or a visit to the study site is scheduled on an alternating basis. In addition, one visit before and up to two visits after the treatment period are planned. During the study, the study team will: - Check vital signs such as blood pressure and heart rate - Examine the participants' heart health using an electrocardiogram (ECG) - Take blood samples - Ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, the participants will be asked to complete a questionnaire on quality of life at certain time points during the study.
This study aims to observe the impact of COVID-19 infection on the reproductive function and assisted pregnancy outcome of infertile couples undergoing assisted reproductive technology and to determine which factors are related to the clinical pregnancy rate. A multicenter, prospective, observational cohort study was adopted. Infertile couples who met the selection criteria were included in this study, the SAS anxiety self-rating scale was filled out, the basic situation was observed, and blood samples and related tissues were collected for testing. Relevant reproductive function, laboratory, clinical, and psychological indicators were collected, and the correlation between the above indicators and the outcome of the ART-related pregnancy were analyzed.
This multi-center, retrospective cohort study aimed to determine which factors are associated with ongoing pregnancy rates in infertile patients received ART treatments during the current outbreak of COVID-19 infection.Couples who underwent IVF-ET/ICSI-ET/FET due to infertility in the department of Reproductive Medicine from 2022-11-23 to 2023-01-07 were included. Patients who were infected with Coronavirus were observation groups; the infection status and clinical outcome were tracked. Patients who were not infected with Coronavirus were control groups.
The goal of this observational study is to determine 30-day mortality and post endoscopic surgery complications in patients with COVID-19 infection who undergo endoscopic surgery.This results will inform future risk stratification, decision making and improve patient's clinical care.This study is an investigator-led, non-commercial, non-interventional study is extremely low risk, or even zero risk.
The First Affiliated Hospital of China Medical University initiated a multi-center study to evaluate the changes of maternal fetal heart structure and function in pregnancies with cardiovascular disease by echocardiography, to explore the impact of cardiovascular disease on maternal fetal heart, so as to provide an important reference for obstetric pregnancy risk stratification and management.
This is an open-label study. This study includes 2 parts, in which part 1 is a relative BA study, Part 2 is a DDI study. Part 1 and Part 2 could be performed in parallel.
We intend to establish an efficient method for plasma cfDNA extraction and Bisulfite transformation to facilitate the detection of DNA methylation status using multiplex fluorescence PCR. Meanwhile, we expect to identify several plasma methylation markers that can be highly sensitive for multi-cancer detection. Finally, we will provide a pan-cancer blood test that is easy to operate, low cost, accurate and easy to promote.
The purpose of this clinical trial is to learn about the safety of the study medicine (ponsegromab) and how it undergoes change and elimination in healthy Chinese adults. This study is seeking male and female Chinese participants who are very healthy as confirmed after some medical tests. All participants in this study will receive Ponsegromab only once: - for half of the participants, ponsegromab will be given as a shot in the front of the thigh, abdomen, or outer area of the upper arm at the study clinic. - for another half of the participants, ponsegromab will be given as four shots in the front of the thigh, abdomen, or outer area of the upper arm at the study clinic. We will measure the amount of the study medicine in the blood of the participants after giving the shots. Later we will examine experiences of people receiving the study medicine. This will help us understand how the medicine is changed and eliminated from your body and to decide if the study medicine is safe. Participants will take part in this study for 22 weeks. During this time, they will stay at the study clinic for the first 8 days and will visit the study clinic about 8 times.
This study is looking at how Mim8 works in people with haemophilia A, who either have inhibitors or do not have inhibitors. Mim8 is a new medicine that will be used to avoid bleeding episodes. Mim8 works by replacing the function of the missing clotting factor VIII (FVIII). When and how often the participants will receive Mim8 in this study depends on the treatment participant receives in the current Mim8 study participant is taking part in. The study will last for up to 5.5 years. The duration of the study depends on when the participant enrolled in this study. The study will end if Mim8 is approved and marketed in participant's country during the study, or the study will end in 2028, whichever comes first. Mim8 will be injected under the skin with a thin needle either once a week, once every two weeks or once a month. Participants will get up to 262 injections; the number of injections depends on how often participants will get injections. While taking part in this study, there are some restrictions about what medicine participants can use. The study doctor will tell the participants more about this. In case the participants experience bleeds, these can be treated with additional haemostatic medicine as agreed with the study doctor. Female participants cannot take part if they are pregnant, breast-feeding or plan to get pregnant during the study period.
This is a randomized, double-blinded, placebo-controlled clinical trial to determine the efficacy and safety of a Chinese herbal medicine (Shenlingcao oral liquid) for treating long COVID associated fatigue.
