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 Phase II, open-label trial to evaluate the efficacy and safety of AK104 monotherapy or AK104 in combination with axitinib as a first-line treatment for advanced/metastatic renal cell carcinoma (RCC). There are two parts in this trial. In part 1 of this study, subjects with unresectable advanced clear cell or non-clear cell renal cell carcinoma (ccRCC or nccRCC) who had not received systemic therapy for advanced disease will be enrolled to randomly received three different dosage of AK104 monotherapy. In part 2 of this study, subjects with unresectable advanced clear cell renal cell carcinoma (ccRCC) who had not received systemic therapy for advanced disease will be enrolled to receive AK104 plus Axitinib. All subjects will receive treatment until disease progression, development of unacceptable toxicity, death, a decision by the physician or patient to withdraw from the trial. The primary endpoint is ORR per RECIST v1.1 as assessed by investigators.
The Westlake Longevity Cohort (We-Longevity) is a prospective cohort study among centenarians, nonagenarians, senior citizens and their family members up to three generations living in Lishui, China. The primary aim of this cohort is to characterize the multi-omics molecular characteristics of healthy longevity and their dynamic trajectories. Another aim of We-Longevity is to investigate the association of dietary and lifestyle with the multi-omics molecular characteristics of healthy longevity, and to facilitate the development of personalized nutritional/lifestyle recommendation for the public.
Epilepsy is one of the common chronic diseases of the central nervous system. 30% to 40% of patients with epilepsy have varying degrees of cognitive impairment, which affects their quality of life. At present, the treatment of cognitive impairment in patients with epilepsy is relatively scarce, and the therapeutic effect is still not ideal. Recent studies have shown that sleep disorder is also an important factor causing cognitive dysfunction, and improving sleep quality has a prospect to become a new way to treat cognitive impairment in patients with epilepsy. The purpose of this study is to observe the relationship between sleep and cognitive function in patients with epilepsy, and to improve the sleep quality of patients with epilepsy, so as to provide new ideas for improving cognitive impairment in patients with epilepsy.
This is a prospective/retrospective, observational follow-up study of effects of fatty liver on chronic hepatitis B. Patients will join this study who undergo transient elastography with liver stiffness (LS) and CAP measurements or Ultrasonic examination. All recruited subjects will undergo comprehensive clinical, anthropometric and laboratory assessments at the time when transient elastography or Ultrasonic examination is performed. We plan to compare the relationship between chronic hepatitis B and non-alcoholic fatty liver disease. Patients will be divided into several groups based on the demand.
According to the existing literature reports, the misdiagnosis rate of CT is as high as 22% - 68%. Thymic cyst and lymphoma are usually misdiagnosed as thymoma, resulting in many unnecessary operations; In addition, traditional imaging technologies can also cause a missed diagnosis rate of about 7%, which is common in the missed diagnosis of asymptomatic thymoma, which delays the opportunity of treatment. Therefore, in order to accurately treat thymic tumors, the existing diagnostic methods of thymic tumors need to be further optimized. Our previous retrospective study found that the level of IL-8 + initial T cells can well distinguish thymoma from other types of anterior mediastinal tumors, and the sensitivity and specificity are close to 95%.
The incidence and mortality of hematological malignancies remain high. Although 18F-FDG PET/CT imaging is the most common molecular imaging technique used in clinic, the non-specific uptake of 18F-FDG leads to the problems of false negative or positive in hematological malignancies, which makes it difficult to diagnose and evaluate the efficacy. CXCR4 (C-X-C Chemokine Receptor Type 4) is overexpressed in various hematological malignancies, and is associated with poor prognosis. CXCR4-targeted molecular imaging, such as 68Ga-pentixafor PET/CT imaging, has an important potential in hematological malignancies. Therefore, this study will evaluate the efficacy of CXCR4-targeted PET/CT imaging for diagnosis and staging of hematological malignancies, compared with 18F-FDG PET/CT imaging.
This project intends to evaluate the sensitivity of different Homologous Recombination Deficiency (HRD) score to Poly(ADP-ribose) polymerase inhibitor (PARPi) by retrospectively analyzing the tissue samples of patients with ovarian cancer using PARPi, and to determine the cut off value of the HRD score algorithm suitable for the Chinese population, so as to provide evidence for the role of PARPi in ovarian cancer. The screening of the beneficiaries of maintenance therapy provides precise guidance and can be used as a reference for other cancer types.
The IOL-capsular complex is formed after cataract surgery and intraocular lens (IOL) implantation. Early postoperative mechanical wrapping of the anterior and posterior capsules plays a significant role in preventing IOL decentration and tilt, as well as formation of the IOL-capsular complex which reduces the incidence of posterior cataract opacity. IOL decentration ≥ 0.4 mm or/and IOL tilt ≥7degree were considered clinically significant cause of poor post-surgery visual quality especially for optical sophisticated IOLs. This negative impact does not affect various types of IOLs equally. Several studies indicated that AL was an independent risk factor of IOL decentration and tilt for emmetropic or moderate myopic eyes. For patients with high myopia, they often have a longer axial length and a larger capsule diameter, which reduces the rotational stability of the IOL and may lead to tilt, decentration and displacement of IOL. Currently, there is no literature guidance to compare the results of cataract surgery combined various types of IOLs implantation in patients with high myopia. The novel anterior segment optical coherence tomography (AS-OCT) device, CASIA2 can evaluate the IOL capsule bending and the lens position after cataract surgery. Also, CASIA2 can be used to documented the dynamic changes of IOL-capsular complex after surgery.
This is a randomized, double-blind, placebo-controlled phase 3 clinical study evaluating the long-term efficacy and safety of AK102 in patients with primary hypercholesterolemia and mixed hyperlipidemia.
The aim of this phase Ⅱ study is to evaluate the efficacy and safety of Furmonertinib in EGFR-Mutant, PD-L1+ Patients With Locally Advanced or Metastatic NSCLC.
