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 immune mechanism of the nucleos(t)ide analogs (NAs) in inhibiting HBV replication effectively while having a low sustained virus control rate after drug withdrawal is unclear. B cell immunity and antibody response are the keys to prevent HBV reinfection and keep the virus under control. T-bet+ B, which can be regulated by IL-21, is a newly discovered major effector B cell in protection of pathogens and it is a main subtype of HBsAg-specific B cells. Thus, we suspect that T-bet+ B may play a role in ongoing controlling of the virus after withdraw of NAs in CHB patient. Based on our previous studies on CHB immunity, we use the RNAseq analyse, flow cytometry, and Elispot assay to analyze the frequency, function, and phenotype of B cells in CHB patients with different profiles after withdraw of NAs.
The aim of this study is to explore the advantages of robot-assisted thymectomy in long-term survival benefits and short-term clinical efficacy compared with video-assisted thoracoscopic thymectomy based on a multi-center, prospective, randomized controlled clinical trial.
The objective of this prospective, observational, controlled clinical study is to use magnetically-controlled capsule gastroscopy for postoperative assessment in elderly patients and patients with underlying diseases, to evaluate its clinical efficacy and safety.
This study is a single-arm, self-controlled clinical trial that explores and evaluates the efficacy of middle meningeal artery embolization with coil in improving migraine symptoms. The main objectives of the study are to evaluate the effectiveness and safety of the treatment.
The main objective of this study is to evaluate the anti-tumor activity of BGB-A445 plus investigational agents in participants with non-small cell lung cancer (NSCLC)
Scientific Rationale: High risk localized prostate cancer (PCa) is associated with higher rates of biochemical recurrence, clinical recurrence, metastasis and PCa-specific death. Novel hormone therapies(NHT) have shown a significant survival advantage with respect to classical ADT in later stages of PCa and have already been investigated in neoadjuvant setting. PURPOSE: To assess antitumor effect by measuring pathological tumor volume with pathological downstaging following radical prostatectomy + pelvic lymph-node dissection (RP + PLND) for high-risk localized prostate cancer patients.
The current study is going to investigate the music intervention on the table tennis stroke performance among table tennis stroke performance. The subjects will be instructed to listen to 3 minutes, which can facilitate the recovering process for scope of attention and thought-action repertoire. Thus, to see the improvement in stroke performance.
Whether toripalimab plus actinomycin-D as fist-line treatment can achieve a higher complete response rate than actinomycin-D alone. Whether an equally high cure rate can be achieved by multi-drug chemotherapy as second-line treatment in patients who have failed fist-line treatment with toripalimab plus actinomycin-D. Participants will be allocated into two groups. Those in experimental group will receive toripalimab plus actinomycin-D, while those in control group will receive actinomycin-D alone. Treatment will be continued until disease progression, unacceptable toxicity, or withdrawal of consent. Treatment will be completed after 3 consolidation cycles.
The goal of this clinical trial is to evaluate the efficacy and safety of albumin-bound paclitaxel-lenvatinib-pembrolizumab in advanced nonsquamous NSCLC patients after progression to first-line anti-PD-1/L1 inhibitor with platinum-doublet chemotherapy. All participants will be given with albumin-bound paclitaxel, lenvatinib and pembrolizumab.
We first collect tumor tissue and adjacent tissue to peform the WES sequencing, then collect blood after postoperative surgery 1, 3. 6, 9, 12, 18, 24 month to detect ctDNA.
