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.
Liquid biopsy based on next-generation sequencing (NGS) method has become an increasingly powerful detection tool for clinical research and practice. As a companion diagnostic panel, circulating tumor DNA (ctDNA) assay has the considerable potential to detect the blood tumor mutation burden (bTMB), and bTMB calculated by ctDNA assay is regarded as a novel and promising biomarker for immunotherapy nowadays. Though immune checkpoint inhibitors (ICIs) in immunotherapy are highly effective but can induce severe immune-related adverse events (irAEs), which cannot be better predicted in advance. Meanwhile adoptive transfer of T cells transgenic for tumor-reactive T-cell receptors (TCR) is an attractive immunotherapeutic approach. However, clinical translation is so far limited due to challenges in the identification of suitable target antigens as well as TCRs that are concurrent safe and efficient. Definition of key characteristics relevant for effective and specific tumor rejection is essential to improve current TCR-based immunotherapy. This research is to characterize in-depth TCRs derived from HLA-mismatched allogeneic repertoire targeting different myeloperoxidase (MPO)-derived peptides presented by the same HLA-restriction element. Overall the purpose of this trial is to investigate the combined predictive biomarkers (including bTMB and HLA) related to the immunotherapy effects and the biomarker (TCR) associated with adverse reactions during immunotherapy and hold a predictive role, thus further benefit patients receiving immunotherapy, especially in the advanced stage lung cancer patients where tissue samples are unavailable.
This prospective, single-arm study is conducted to investigate the safety and efficacy of Sintilimab combined with hypofractionated radiotherapy in patients with microsatellite instability-high (MSI-H)/ DNA mismatch repair-deficient (dMMR) non-metastatic rectal cancer.
Recurrent or advanced cervical neuroendocrine carcinoma (NEC) is refractory to multimodal treatment, even to extensive therapy. Chemotherapy, consisting of platinum and etoposide, remains the main therapy for recurrent or advanced cervical NEC. In addition, bevacizumab has shown progression-free benefits in recurrent or advanced cervical cancer. Case report suggested anti-PD-1 antibody may have antitumor activities in NEC. Based on these evidences, a phase 2, single arm trial is conducted to explore the objective response rate (ORR) of platinum/etoposide/bevacizumab/anti-PD-1 antibody (camrelizumab) for the treatment of recurrent or advanced cervical NEC. This trial is to enroll 20 patients, who would accept 6 courses of platinum/etoposide/bevacizumab/camrelizumab. If the patient achieved complete or partial remission, a total period of 12 months bevacizumab/camrelizumab will be given as maintain therapy. The primary endpoint is ORR. The second endpoints are severe adverse events according to criteria of Common Terminology Criteria for Adverse Events (CTCAE) and iRECIST Guideline, and critical changes of laboratory testing.
Mid to low-lying rectal cancer patient with enlarged lateral lymph node befor treatment and receiving lateral lymph node dissection would be enrolled. Radiomics parameters of lateral lymph nodes would be extracted by expert software. Then a part of the nodes would be used as the training set to build the prediction model, and the another part nodes would be used as the validation set.
The purpose of this study is to evaluate the efficacy and safety of talquetamab in participants with relapsed or refractory multiple myeloma at the recommended Phase 2 dose(s) (RP2Ds) (Part 3).
The study aims to evaluate the efficacy and safety of PD-L1 antibody combined with the CTLA-4 antibody in patients with advanced ICC who progressed after standard treatment.
Portal hypertension is characterised by an increased portal pressure gradient (PPG), that is the difference in pressure between the portal vein and the inferior vena cava (IVC). Portal hypertension is a consequence of cirrhosis resulting from chronic hepatitis. Patients with portal hypertension are at risk of developing complications including oesophageal or gastric varices, variceal bleeding, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy and mortality. Albeit its clinical significance, direct measurement of portal venous pressure to document portal hypertension has traditionally been difficult. The portal vein pressure can be measured by transhepatic or transvenous methods but the procedure carries a risk of intra-peritoneal bleeding. Furthermore, the IVC pressure measurement requires further transjugular catheterisation. Hence, the technique is rarely used. Currently, the gold standard in measurement of portal hypertension is via measurement hepatic venous pressure gradient (HVPG). The HVPG has been shown to correlate with risk of clinical decompensation, development of varices, hepatocellular carcinoma, variceal bleeding, spontaneous bacterial peritonitis and mortality. Nevertheless, the technique has a low acceptance rate amongst patients and it may not be available even in tertiary medical centres. Recently, the use of EUS-guided approach for measurement of portal pressure gradient (PPGM) has been shown to be feasible. The technical success rate was 100% and no adverse events were reported. Measurements obtained with the EUS approach was shown to correlate excellently with clinical parameters of portal hypertension including presence of varices, portal hypertensive gastropathy and thrombocytopenia. Furthermore, the procedure could be performed at the same time of screening oesophagogastroduodenoscopy (OGD), that is frequently required for variceal screening in this group of patients. Hence, the aim of the current study is to investigate the feasibility of EUS-PPGM and correlate the risk of developing complications with the PPGM in patients that are suffering from chronic hepatitis.
This is a multi-centre, randomised, double blind, placebo-controlled study on female participants with diagnosis of high-risk human papillomavirus (HR-HPV) infection to evaluate the clearance capacity of AHCC®.
The objective of this study is to compare the safety and efficacy of 0.25% HBM9036 (HL036) Ophthalmic Solution to placebo for the treatment of the Chinese subjects with moderate and severe dry eye.
This is an open label Phase 1/2 study, the purpose of the trial is to assess the safety, tolerability, pharmacokinetics, and antitumor activity of ASKB589 in patients suffering from advanced or metastatic solid tumors. Patients with gastric cancer/gastroesophageal junction adenocarcinoma and pancreatic cancer are preferred.
