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.
Study D0817R00081 is a retrospective study using NCID database to assess the safety of Olaparib in Chinese patients with ovarian cancer by examining the incidence, seriousness, and severity of all AEs, including but not limiting to AESIs and SAEs, AEs related to Olaparib, and AEs leading to dose reduction, interruption or discontinuation of Olaparib. The first Olaparib prescription date will be set as the index date. The baseline period is from the patient's first ovarian cancer diagnosis recorded in the database to the patient's first treatment with Olaparib (as early as the database start date of January 1, 2013) to the index date for derivation of lines of therapy or one year pre-index date for other baseline variables. Patients will be followed until the patient's last medical record in the database, 30 days after the last dose of Olaparib, death, or June 30, 2023, whichever comes first. All patients who meet the inclusion/exclusion criteria will be enrolled.
The investigators will conduct randomized and controlled clinical studies in order to preliminarily explore the efficacy and safety of low-dose cyclophosphamide and lenalidomide in maintenance therapy for MM that is not suitable for transplantation in the standard-risk group.
Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related death worldwide. Colonoscopy is considered the preferred method of screening for colorectal cancer, and resection of colorectal lesions can significantly reduce the incidence and mortality of colorectal cancer. In order to improve the qualitative and quantitative diagnosis of colorectal lesions, many endoscopic techniques, such as image-enhanced endoscopy (IEE), including narrowband imaging (NBI), magnifying endoscopy, pigment endoscopy, confocal laser endoscopy, and endocytoscopy (EC) are applied clinically. The application of EC is intended to achieve the purpose of real-time histopathological endoscopic diagnosis without biopsy. Several studies have shown that EC is effective in identifying the nature of colorectal lesions and judging the depth of invasion in CRC. Based on the endoscopic diagnosis, the endoscopist can determine the treatment plan for the colorectal lesions. The latest EC is an integrated endoscope with a contact light microscopy system with a maximum magnification of 520 x. EC may demonstrate the atypical of gland structure and cells after staining (EC staining mode, along with the use of the EC-NBI mode. The endoscopic diagnosis of the EC staining mode is based on the EC classification (EC-C), used to predict the histopathological diagnosis of colorectal lesions. A prospective randomized trial showed that the diagnostic accuracy was 94.1% by EC-C. However, the diagnostic value of EC-C depends on the operator and may be influenced by the quality of the staining. Meanwhile, the high-quality staining process is time-consuming and tedious. Therefore, EC-NBI seems to be the first choice for EC diagnosis with the advantages of convenient operation and efficient diagnosis. EC-NBI can display the super-amplified surface microvessels of the lesion and provide pathological prediction according to the vessel classification (EC-V). EC-V achieved 99% diagnostic accuracy for hyperplastic polyps and 88.6% for invasive carcinoma. In EC examination, the investigators usually use EC-NBI and EC staining successively to diagnose colorectal lesions, which is believed to improve the diagnostic performance. However, the diagnostic value of increasing EC-staining after EC-NBI examination for predicting the pathological nature of colorectal lesions is still unclear. Therefore, this retrospective study aimed to evaluate the diagnostic value of two different modalities of cell endoscopy for colorectal lesions and to clarify whether additional EC staining after EC-NBI could improve the diagnostic performance of predicting the pathological diagnosis of colorectal lesions. In the study, the investigators collect clinical information of colorectal lesions which were diagnosed by endoscopic diagnosis (including EC-NBI and EC-staining) and pathological diagnosis. Then, the investigators calculate the accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and high confidence diagnosis rate of EC-C and EC-V classification, respectively. Inter-and intra-observer agreement in the diagnosis of EC-C and EC-V will be calculated.
Previous clinical practice and exploratory studies suggest that some patients who have not achieved functional cure in the first round of interferon therapy can achieve HBsAg clearance by interferon retreatment (intermittent therapy), which can reduce the occurrence of complications such as liver fibrosis, liver cirrhosis and liver cancer, and its clinical benefit is expected to be higher than that of NAs monotherapy. This study is aimed to conduct a large-scale, multicenter, prospective study to confirm the benefit of peginterferon-based therapies in these populations. It expected to enroll about 2000 patients with chronic hepatitis B who have received prior interferon therapy and achieved a good response but without function cure, patients receive either interferon-based therapy or NAs monotherapy, according to their wishes and doctors' professional recommendations, with a ratio of 2:1 between the two groups, and all patients treated for 48 weeks. The HBsAg clearance rate before and after treatment, safety, etc. will be analyzed.
The safety and efficacy of the chimeric antigen receptor (CAR)-T, a CD19-targeting, TRAC and Power3 double genes deleted allogeneic CAR-T cell product, are undergoing rigorous evaluation in non-Hodgkin's lymphoma (NHL) subjects from our ATHENA trial (NCT06014073). Unexpectedly, expansion of the initial residual CD3-positive CAR T from products were measured in patients' peripheral blood (PB) without exception. Accompanying with host immune reconstitution and appearance of the detectable B cells, the CD3-positive allogenic CAR T cells exhibited a compelling amplification advantage over CD3-negative CAR T cells. The amplification of CD3-positive CAR T cell population dynamically suppressed host B cell recovery, and presumably surveilled the recurrence or progression of tumors, but did not induce typical Graft-versus-host-disease (GvHD). Additionally, a series of in vitro experiments illustrated that the HLA-mismatched fratricide between host T cells and TCR-reserved Power3-deleted allogenic CAR T cells was markedly slashed, which in combination with our observed clinical safety date supported the notion that only genomic deletion of Power3 gene in allo-CAR T cells is sufficient to overcome GvHD and host T cell-mediated rejection response. In the ATHENA-2 study, our design is to preserve the expression of the TCR on T cells from healthy donors while selectively disabling the Power3 gene to prepare ATHENA-2 CAR T cells. This approach harnesses the tonic signaling of CAR T cells, resulting in enhanced persistence and improved response to treatment. The purpose of this study is to evaluate the safety and efficacy of ATHENA-2 in B-cell NHL.
Atezolizumab + Bevacizumab was superior to sorafenib in overall survival in advanced hepatocellular carcinoma. The programmed cell death protein-1 (PD1) and PDL1 inhibitor, was effective and tolerable in patients with advanced hepatocellular carcinoma. We aimed to describe the efficacy and safety of locoregional therapy combined with Bevacizumab and PD1/L1 inhibitor in patients with advanced hepatocellular carcinoma who can not receive radical therapy.

This study is conducted in critically ill children with sepsis with a five years follow-up. We aim to investigate the impact of sepsis on long-term outcomes including growth, neurodevelopment, survival rate, quality of life.
This study will look at how much CagriSema helps participants with type 2 diabetes lower their blood sugar and body weight. CagriSema is a new investigational medicine. Doctors may not yet prescribe CagriSema. CagriSema will be compared to a "dummy" medicine (also called "placebo") that has no effect on the body. Participants will get either CagriSema or "dummy" medicine. Which treatment participants get is decided by chance. For each participant, the study will last for about one year.
