The goal of this study is to evaluate nemtabrutinib compared with investigator's choice of ibrutinib or acalabrutinib in participants with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who have not received any prior therapy. The primary hypotheses are that (1) nemtabrutinib is non-inferior to ibrutinib or acalabrutinib with respect to objective response rate (ORR) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 by blinded independent central review (BICR) and (2) nemtabrutinib is superior to ibrutinib or acalabrutinib with respect to progression free survival (PFS) per iwCLL Criteria 2018 by BICR.
This study was divided into four stages: screening period, main trial period, extension period and follow-up period. In the main trial, both groups received FRSW107 prophylactic therapy. The recommended initial dose of prophylactic administration was 50 IU/kg, the dose range was 25 to 50 IU/kg, and the recommended frequency of administration was once every three days (Q3D). The dose range could be adjusted according to the patient's response. The main trial period was prophylaxis up to ≥50 exposure days (EDs) and ≥6 months. The investigator may adjust the dose according to the clinical efficacy of the subjects (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ valley according to the following principles. If necessary, the investigator may adjust the dosing interval according to the clinical efficacy of the subject (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ. Investigators are advised to inform sponsors or their research partners when adjusting doses and dosing intervals during prophylaxis. After participants completed prophylaxis until ≥50EDs and ≥6 months, participants' willingness and investigator evaluation were used to decide whether to enter the extended trial. All subjects entering the extended phase continued with the original prophylactic regimen until 100EDs was dosed. During the main trial period and the extended preventive treatment period, if the subjects have breakthrough bleeding events requiring treatment, hemostatic treatment of breakthrough bleeding with investigational drugs can be performed. The researchers can refer to the treatment guidance for different degrees of bleeding in Table 6-1. Taking into account the subject's prophylactic dose, severity of bleeding, site and extent of bleeding, clinical status, and previous PK results (if any), the investigator determines the appropriate dose to administer (recommended dose range: 25 to 50 IU/kg) and dosing times until the investigator assessed significant control of bleeding episodes (e.g. reduction of pain and swelling) or return to pre-bleeding activity. If the bleeding episode stops, the subject will continue with the same dose and frequency of prophylactic medication as before the bleeding episode.
Trial Title: Prospective, multicenter, single-arm target value clinical trial to evaluate the safety and efficacy of a transcatheter aortic valve system in the treatment of patients with severe aortic stenosis Test device: Transcatheter aortic valve system. Pilot Phase: Clinical Validation of Class III Medical Devices. Study design: prospective, multicenter, single-group target value. Sample size: 120 cases. Intended Use: The Transcatheter Aortic Valve System is indicated for patients with a diagnosis of severe aortic stenosis by the Comprehensive Heart Team. Objective: This clinical trial is a prospective, multicenter, single-arm study to evaluate the safety and efficacy of the transcatheter aortic valve system in the treatment of patients with severe aortic stenosis. Primary endpoint: 12-month postoperative all-cause mortality All-cause deaths include cardiac death and non-cardiac death. Secondary Endpoints: 1. Device success rate 2. Procedural success rate 3. Delivery system performance 4. Retrieval system performance (e.g. using a recycling system) 5. Exchange system performance 6. Valvular function at Immediately postoperative, 7 days/at discharge, 30 days, 6 months, 12 months, 2-5 years follow-up: valve stenosis, regurgitation, valve function (e.g., opening area, pressure gradient), paravalvular leakage 7. Improvement in quality of life at 30 days, 6 months, 12 months postoperatively 8. Improvement in cardiac function at 7 days/at discharge, 30 days, 6 months, 12 months, 2-5 years postoperatively Experimental design: This trial is a prospective, multicenter, single-group clinical study with a target value to evaluate the Transcatheter Aortic Valve system Safety and efficacy in the treatment of patients with severe aortic stenosis with 12 months of All-cause mortality after transcatheter aortic valve implantation. The mortality rate was the primary study endpoint, and after statistical assumptions and sample size calculations, 120 patients were planned to be enrolled. Patients were clinically followed immediately after valve implantation, 7 days postoperatively/at discharge, 30 days, 6 months, 12 months, and 2-5 years postoperatively. In this trial, all relevant clinical data were collected, sorted out and statistically analyzed by an independent data management and statistics center and a clinical monitoring institution. All enrolled subjects underwent outpatient follow-up at 30 days, 6 months, and 12 months after surgery, and performed relevant imaging examinations (ultrasound, etc.) and laboratory tests and safety evaluations, and continuous follow-up and cardiac ultrasound examinations were performed annually at 2-5 years to observe the occurrence of adverse events to evaluate the long-term safety of the transcatheter aortic valve system. The safety and efficacy of the transcatheter aortic valve system were evaluated with the subject's 12-month postoperative all-cause mortality as the primary endpoint, and the immediate postoperative device success rate, procedural success, retrieval system performance, valve function, cardiac function improvement, quality of life improvement, all-cause mortality in different follow-up periods, major adverse cardiovascular and cerebrovascular events, myocardial infarction, stroke, hemorrhage, acute kidney injury, permanent pacemaker implantation, serious vascular complications, and other TAVR-related complications were taken as the secondary endpoints to assist in evaluating the safety and efficacy of the test product, and to provide a basis for the final official listing and domestic marketing.
To evaluate the tolerability and safety of SENL101 in patients with relapsed or refractory T-LBL/ALL.
The purpose of this study is to evaluate the efficacy and safety of Zanubrutinib given in combination with bendamustine and rituximab in (elderly or TP53 alterations or chemotherapy intolerance) patients with newly diagnosed mantle cell lymphoma.
This is a multi-center, single arm, open-label, phase I study to determine the safety and effectiveness of EBV-TCR-T cell immunotherapy in treating EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) or EBV infection
CHina Registry for the chAracteristics and Management strategieS of patiEnts With Pulmonary Hypertension Using Targeted Therapy (CHASE Study)
The aim of this study was to evaluate the safety, tolerability, and pharmacokinetic characteristics of TNP-2092 Capsules in liver cirrhosis patients with hyperammonemia; and to preliminarily observe the effects of the study drug on blood ammonia and hepatic encephalopathy related clinical symptoms and signs, neuropsychological indicators, and quality of life in liver cirrhosis patients with hyperammonemia.
The goal of this observational study is to learn about the the pattern of metastasis of the No.253 lymph node in colorectal cancer. The main questions it aims to answer are: 1. What are the risk factors for metastasis to the No.253 lymph node? 2.What is the prognosis for patients with metastasis to the No.253 lymph node? Patients with descending colon cancer, sigmoid colon cancer, and rectal cancer who undergo curative surgery with dissection of the No.253 lymph node are included in this study
In this study, patients will receive bupivacaine liposome serratus anterior plane block or ropivacaine paraspinal block to manage postoperative pain. Follow-up visits will be conducted to investigate the patient's postoperative pain and recovery quality. The investigators hypothesize that the simple and safe serratus anterior plane block with a novel long-acting local anesthetic (bupivacaine liposome) has analgesic efficacy and recovery quality that is not inferior to the currently commonly used bupivacaine paraspinal block.
