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.
The purpose of this study is to establish the large PH cohort and biological database in China, aiming for precision medicine to optimize diagnosis and treatment choices.
Untreated patients with Nodal T-follicular Helper (TFH) Cell Lymphoma will be treated with chidamide combined with azacitidine for four cycles. For patients with interim evaluation of CR, consolidation therapy with ASCT or another eight cycles with chidamide combined with azacitidine can be obtained. For patients with interim evaluation of PR, another two cycles of chidamide combined with azacitidine will be continued, followed by the second efficacy evaluation, and those who achieve CR receive consolidation therapy with ASCT or another six cycles of chidamide combined with azacitidine. Subsequently, chidamide was given as maintenance therapy for 12 months. Patients with SD or PD withdrew from this study.
Based on the biological-psychology-sociological medicine pattern, this study aims to construction an early warning model of the New Psychoactive Substances (NPS) using for adolescents aged 14-35 years old. This study intends to obtain the data related to the behavioral expression of addiction susceptibility genes, adverse childhood experience, cognition, resistance and the use of NPS in adolescents by questionnaire survey (sample size: 200), and then use logistic regression and machine learning to construct an early warning model.
Males with non-obstructive azoospermia (NOA) have an opportunity to obtain sperm by treatment with microdissection testicular sperm extraction (mTESE), gold-standard surgical technique for them. The overall sperm retrieval rate (SRR) of mTESE in NOA patients is about 50%, but the predictive factors of SRR remain were understudied, especially the effect of age. The purpose of this study was to explore the factors influencing the SRR of mTESE in NOA patients with different etiologies. Methods: This observational study recruit NOA patients treated with their first mTESE. The stratified research was used to investigate SRR by dividing patients into seven groups based on etiology. The primary outcome was SRR. Multivariable logistic regression was used to analyze the factors influencing SRR.
1. Preliminarily explore the correlation factors of differences in the efficacy of levamlodipine besylate in the treatment of hypertension. 2. Quantitatively analyze the influence of covariates such as patient demographic factors, personal history, combined medications, and biochemical indicators on the efficacy of levamlodipine besylate, and establish a population pharmacokinetic model of levamlodipine besylate, to achieve clinical Individualized treatment and rational drug use.
Exploring the efficacy and safety of oral minocycline combined with antiepileptic drugs in the treatment of drug-resistant epilepsy in NORSE patients, obtaining preliminary research data, and providing evidence and data support for the next large-scale randomized controlled clinical study.
The goal of this observational study is to establish an evaluation system for accurate identification of prostate cancer and prostatic hyperplasia in patients in the PSA gray zone. The main questions it aims to answer are: proportion of men who could have avoided biopsy with positive PSMA-PET and no clinically significant cancer detected on biopsy; develop a nomogram of biomarkers (PSA) + imaging (PSMA) to predict the likelihood of clinically significant prostate cancer in men pre-biopsy. Participants will: 1. undergo PSMA PET/CT and multiparameter MRI; 2. undergo biopsy; and 3. undergo radical prostatectomy for biopsy-proven clinically significant prostate cancer. Researchers will compare the PSMA PET/CT-based features between prostate cancer and benign prostatic hyperplasia to see if there are differences in semiquantitative parameters.
This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks). Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue. The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy. Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.
In spinal cord tumors requiring surgical intervention, the resection difficulty is determined by two significant factors: tumor stiffness and adhesion to surrounding tissue. The stiffness of the tumor dictates the complexity of removal, while strong adhesion presents additional challenges during the surgical procedure. This clinical trial aims to assess the clinical utility of magnetic resonance elastography (MRE), in evaluating the stiffness and adhesion of spinal cord tumors and guiding surgical planning to selecting the most appropriate surgical approach for patients with spinal cord tumors.
