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.
This is a multicenter II study to compare KN026 and KN046 versus Oxaliplatin, Capecitabine combined KN026 and KN046 in patients with HER2-positive locally advanced resectable gastric cancer or gastroesophageal junction adenocarcinoma.
The goal of this clinical trial is to compare the clinical outcomes using different cetrorelix acetate in the context of a GnRH antagonist protocol for ovarian stimulation in women undergoing IVF or intracytoplasmic sperm injection(ICSI) treatment.The main question it aims to answer is whether the generic cetrorelix acetate is non-inferior to the reference product in the GnRH antagonist based protocol for women undergoing IVF. Ovarian stimulation was achieved by several types of follicle-stimulating hormone(FSH) or by FSH combined with luteinizing hormone activity. Daily dose of generic cetrorelix acetate (0.25 mg SC) or original cetrorelix acetate (0.25 mg SC) will be administered when the lead follicle was 14 mm. When more than two follicles reached 17 mm, oocyte maturation was triggered with 250 mcg of recombinant human chorionic gonadotropin.
To assess the efficacy and safety of tezepelumab in pediatric participants with severe uncontrolled asthma on medium to high-dose inhaled corticosteroids (ICS) and at least one additional asthma controller medication with or without oral corticosteroids.
Infertile women attending for PGT at the Centre of Assisted Reproduction and Embryology, Queen Mary Hospital and Kwong Wah Hospital will be recruited during ovarian stimulation for IVF. Subsequently, they will be randomly assigned on the day of oocyte retrieval by a laboratory staff into one of the following two groups in a 1:1 ratio : (1) the microfluidic chip group and (2) the density gradient centrifugation group for sperm preparation and subsequent use in fertilization. Other IVF procedures will be the same as the standard practice of the Centre. Both women and clinicians will be blinded from the group allocation i.e. a double blind study.
Massive blood loss occurs in metastatic spinal tumor resection and may cause severe complications. The objective of this study is to investigate whether the use of tranexamic acid will reduce perioperative and postoperative bleeding when compared to those without use of tranexamic acid.
This multi-modal deep radiomics model, using PET/CT, clinical and histopathological data, was able to identify patients with bevacizumab-sensitive unresectable colorectal cancer liver metastases, providing a favorable approach for precise patient treatment.
This is a real world study to determine the short-term efficacy and safety of Elaboration transcatheter arterial chemoembolization (E-TACE) for hepatocellular carcinoma (HCC)
The study aims to describe the clinical characteristics and clarify the predictors of the short- and long-term outcomes of RHF patients, further assist the diagnosis, risk stratification and treatment of RHF.
Early-onset gastric cancer (EOGC) is a lethal malignancy with a poor prognosis. It differs from late-onset gastric cancer (LOGC) in clinical and molecular characteristics. The current strategies for EOGC detection have certain limitations in diagnostic performance due to the rising trend in EOGC. Hence, identifying novel EOGC bioindicators is crucial.
Orthokeratology(OK) is currently one of the effective methods for treating myopia, reshaping the corneal epithelium to change refractive power. Due to its contact with the ocular surface, long-term wearing could lead to symptoms and signs of dry eye disease(DED) , as well as changes in tear film stability. This prospective study randomly divided 300 children and adolescents with myopia into OK group and spectacles group, with a follow-up of 12 months. At baseline, 1, 3, 6, and 12 months, non-invasive tear breakup time (NIBUT), ocular surface disease index (OSDI) and visual analogue score (VAS) score, tear meniscus height (TMH), conjunctival hyperemia (RS score) and meibomian gland (MG) scores, tear MMP-9 concentration, and point-of-care Lymphotoxin alpha (LTA) test.
