NCT ID: NCT05845554 Recruiting - Clinical trials for Biliary Tract Carcinoma

Application of Chromosomal Instability in Early Diagnosis of Biliary Tract Carcinoma

Start date: March 30, 2023
Phase:
Study type: Observational

Chromosomal instability (CIN) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CIN is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CIN of the DNA extracted from cast-off cells in bile samples seems a promising method for diagnosing, monitoring, and predicting the prognosis of biliary tract carcinoma patients. CIN can be assessed using experimental techniques such as bulk DNA sequencing, fluorescence in situ hybridization (FISH), or conventional karyotyping. However, these techniques are either time-consuming or non-specific. The investigators here intend to study whether a new method named Bile Ultrasensitive Chromosomal Aneuploidy Detection (BileCAD), which is based on low-coverage whole-genome sequencing, can be used to analyze CIN and microbial infection analysis thus help diagnosing and treating biliary tract carcinoma patients.

NCT ID: NCT05845372 Not yet recruiting - Clinical trials for Acute Ischemic Stroke

Association of Prophylactic Use of Stress Ulcer Drugs and Clinical Outcomes in Patients With Acute Anterior Circulation Thrombectomy

Start date: May 1, 2023
Phase:
Study type: Observational

Ischemic stroke accounts for a relatively high proportion of strokes. In recent years, intravenous thrombolysis and endovascular therapy have significantly improved the revascularization rate in patients with large vessel occlusive cerebral infarction, but 20-50% of patients still experience ineffective revascularization. Therefore, postoperative monitoring and treatment of patients with large vessel occlusions is crucial for early recognition, management and prevention of complications. Stress ulcer bleeding is a serious complication after acute ischemic stroke, with a prevalence of 1%-5%, and a previously proven incidence of stress ulcer bleeding after ischemic stroke. Stress ulcer bleeding after ischemic stroke has been shown to be closely associated with unfavorable outcomes, such as mortality. Current national and international guidelines or consensus on the prevention of stress ulcers after acute ischemic stroke do not advocate the routine use of histamine receptor antagonists or proton pump inhibitors for the prevention of stress ulcers, but rather should be considered in the context of the patient's risk factors for stress ulcers and discontinued after the patient initiates enteral nutrition. However, there is no evidence-based medical evidence to support the risk-benefit relationship of stress ulcer drug prophylaxis in patients with mechanical thrombectomy for acute anterior circulation large vessel occlusion.

NCT ID: NCT05845294 Completed - Colorectal Cancer Clinical Trials

A Study of the Effect of Short-term Structured Psychological Care in Patients

Start date: August 1, 2019
Phase: N/A
Study type: Interventional

The study explored the effects of short-term structured psychological care on the level of postoperative psychological resilience, stigma, anxiety and depression in patients with colorectal cancer colostomy.

NCT ID: NCT05845268 Recruiting - Clinical trials for Locally Advanced Rectal Cancer

Total Neoadjuvant Therapy Combined With Tislelizumab for Local Advanced of Middle and Low Rectal Cancer

Start date: October 1, 2022
Phase: Phase 2
Study type: Interventional

This study is a prospective, randomized, open, controlled, multi-center phase II clinical trial, which included patients with locally advanced low rectal cancer as the research object, and evaluated the application of long-term concurrent chemoradiotherapy combined with tislelizumab versus long-term synchronous Efficacy and safety of chemotherapy and radiotherapy as neoadjuvant therapy for patients with locally advanced rectal cancer. The main endpoints of the study were clinical complete response (cCR) (including imaging and endoscopic complete response) and pathological complete response (pathological complete response, pCR). Secondary study endpoints are primary pathological response rate (MPR), objective response rate (ORR), disease-free survival (DFS), overall survival (OS), organ preservation rate (OPR), rectal cancer neoadjuvant therapy score (NAR ), quality of life score (QoL), safety and tolerability. They will be randomly divided into an experimental group (tislelizumab combined with long-term concurrent chemoradiotherapy) and a control group (long-term concurrent chemoradiotherapy) at a ratio of 2:1. Random stratification factors: 1. TNM stage (II/III); 2. Distance from the tumor to the anal verge (≥5cm, <5cm).

NCT ID: NCT05845151 Recruiting - Lupus Nephritis Clinical Trials

Fibroblast Activating Protein Inhibitor PET Imaging in Lupus Nephritis

Start date: May 1, 2021
Phase: N/A
Study type: Interventional

Abnormal high expression of fibroblast activating protein (FAP) has been found in inflammatory reactions and benign fibrosis tissue. Autoimmune nephropathy such as lupus nephritis (LN) can lead to tubular atrophy and excessive deposition of extracellular matrix, which may be accompanied by abnormally increased expression of activated FAP in kidney tissue, and lead to renal fibrosis and long-term renal failure. This makes 68Ga-labeled FAP inhibitor (FAPI) positron emission tomography (PET) imaging the potential to early assess disease severity, predict disease progress and aid treatment planning in patients with LN. Compared to renal pathological puncture, 68Ga-FAPI PET is a new tool for non-invasive, repeatable assessment of renal fibrotic activation.

NCT ID: NCT05845138 Recruiting - Breast Cancer Clinical Trials

A Study of SHR-A1811 Combined With Capecitabine in Treatment of Unresectable or Metastatic Breast Cancer With Low HER2 Expression.

Start date: July 25, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

The study is being conducted to evaluate the safety, tolerability, preliminary efficacy, pharmacokinetics, and immunogenicity of SHR-A1811 combined with capecitabine in treatment of unresectable or metastatic breast cancer with low HER2 expression.

NCT ID: NCT05845034 Active, not recruiting - Atrial Fibrillation Clinical Trials

A New Theory of Electrophysiological Mechanism of Atrial Fibrillation

ANTEMAF
Start date: April 1, 2023
Phase: N/A
Study type: Interventional

The electrophysiological mechanisms of atrial fibrillation remain disagreements. The goal of this clinical trail is to propose a new electrophysiological mechanism hypothesis of atrial fibrillation(AF),meanwhile, the investigators sought to test the hypothesis that the superposition electrograms (SPEs) recorded during atrial fibrillation could be used as target sites for catheter ablation of atrial fibrillation.

NCT ID: NCT05844956 Recruiting - Clinical trials for Lymphoma, Non-Hodgkin

A Study of DZD8586 in Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma

Start date: June 1, 2022
Phase: Phase 1/Phase 2
Study type: Interventional

This study is designed to evaluate the safety, tolerability, pharmacokinetic profile, and antitumor efficacy of DZD8586 in participants with relapsed or refractory B-NHL.

NCT ID: NCT05844813 Enrolling by invitation - Clinical trials for Retroperitoneal Sarcoma

Neoadjuvant Chemotherapy Combined With Targeted Treatment in High-risk Retroperitoneal Sarcoma

NATARS
Start date: November 1, 2022
Phase: Phase 4
Study type: Interventional

The goal of this clinical trial is to explore the potential survival benefits of neoadjuvant chemotherapy combined with target treatments followed by radical surgery in patients with primary high-risk/grade retroperitoneal sarcoma. The main questions it aims to answer are: - Whether the 1,3-year progression-free survival time(PFS) is prolonged in the neoadjuvant therapy group, compared with the surgery-only group. - The Overall survival time in the two groups. - The safety and tolerance in the neoadjuvant therapy group. Participants will be allocated into two groups once they meet the inclusion criteria. - Surgery-only Group: Patients will directly undergo surgeries after the confirmation of diagnosis through pre-operative biopsy. - Neoadjuvant therapy group: Patients will receive the neoadjuvant chemotherapy combined with target treatment for three circles before the following sarcoma resectional surgeries.
