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 objective is to evaluate the safety, tolerability and pharmacokinetic profile of a single subcutaneous injection of HBM9378 (SKB378) at different doses in healthy Chinese subjects.
The aim of this study is to assess the effect of oral Helicobacter pylori infection on the efficacy of gastric Helicobacter pylori infection eradication. Patients diagnosed with gastric Helicobacter pylori infection are tested for oral Helicobacter pylori and given standard bismuth quadruple therapy, with a urea breath test, a rapid urease test, or a Helicobacter pylori stool antigen test to confirm gastric Helicobacter pylori eradication at week 6 follow-up, and an oral Helicobacter pylori test kit to confirm oral Helicobacter pylori eradication.
Statin treatment significantly reduces the incidence of cardiovascular events. However, cholesterol variability is associated with the risk of adverse events such as mortality, myocardial infarction, and stroke. The previous research found that the inflammatory activity of peripheral blood mononuclear cells in mice fed with intermittent high-fat diet was significantly increased, and the cholesterol variability had an impact on the trained immunity of peripheral blood mononuclear cells, thus aggravating the atherosclerosis in mice. We plan to compare the differences in serum LDL-C levels after intermittent atorvastatin treatment and continuous atorvastatin treatment, and investigate the impact of this difference on the trained immunity of peripheral blood mononuclear cells.

Septic arthritis (SA) is a rare but highly disabling disease. The ideal diagnosis criteria is not well established. There is an urgent need to establish golden standard for diagnosis.
This study is a phase II clinical study of Cadonilimab (AK104) combined with chemotherapy in the treatment of PD-1 inhibitor-resistant nasopharyngeal carcinoma.
Partial nephrectomy(PN) and tumor enucleation(TE) are the two main methods of Nephron-sparing surgery for early renal cell carcinoma. Because of its blunt separation, TE is often considered to be difficult to completely remove tumor tissue. In addition, compared with PN, TE is more difficult and has higher professional requirements for surgeons. Therefore most surgeons use PN. But Many studies have shown that TE has advantages over PN such as less trauma, faster recovery, and better protection of renal function without increasing the risk of tumor recurrence. The main renal artery should be clamped during PN to achieve a relatively bloodless operation environment to ensure the safety of tumor resection. However, too long warm ischemia time will inevitably affect the function of normal renal tissue. Studies have shown that shortening the time of renal ischemia is closely related to the recovery of renal function after the operation. So reducing the time of warm ischemia until zero ischemia has become the pursuit of surgeons. Based on renal cell carcinoma resection combined with zero ischemia technique, renal parenchyma, and renal function can be protected to the maximum extent on the premise of ensuring tumor safety. The purpose of this study is to explore the safety and efficacy of zero-ischemia TE by analyzing the data of early renal cell carcinoma patients who had undergone PN and zero-ischemia TE before.
The most commonly used barrier membrane material in guided tissue regeneration is absorbable collagen membrane. Although the collagen membrane has a good barrier effect, it lacks the growth factors needed for periodontal tissue regeneration, which affects the effect of collagen membrane on periodontal tissue regeneration. Extracellular Matrix Scaffold of Small Intestinal Submucosa (SIS) Membrane is a novel absorbable membrane that retains the extracellular matrix structure and is conducive to vascular ingrowth and tissue repair. The in vitro study showed that SIS membrane had excellent biocompatibility and certain antibacterial effect. Preclinical study also showed that SIS membrane significantly promoted the differentiation of bone marrow mesenchymal stem cells into osteoblasts, and promoted bone regeneration more effectively than collagen mechanism materials. SIS membrane can be used in soft tissue wound repair, guided bone regeneration, site preservation and other surgeries, and has achieved good therapeutic effects. However, whether the application of SIS membrane can achieve good therapeutic effect on periodontal guide tissue regeneration is still unclear. Therefore, in this study, the effects of guide tissue regeneration with collagen membrane and SIS membrane were compared through a randomized controlled clinical study.
In the 30 years fighting against CMV infection, the mortality rate of HSCT patients was significantly reduced. Now we should turn to how to better improve the prognosis of HSCT patients and prevent CMV infection. The emergence of letermovir gave this vision a shot in the arm11-13. Letermovir is the only drug with an indication approved for the prevention of CMV infection in HSCT patients, with a novel mechanism of action characterized by inhibition of the CMV DNA terminase complex. The efficacy and safety of letermovir were well demonstrated in key phase III studies, where letermovir prophylaxis significantly reduced CMV infection and all-cause mortality after HSCT without increased myelosuppression and increased nephrotoxicity (vs. placebo)13. A real-world study of letermovir prophylaxis showed a significant reduction in CMV infection rates (47.0% vs 10.7%), and a significant reduction in antiviral use after 180 days. After more than100 days of continuous use, in addition to a significant reduction in clinically significant CMV infections and patients' overall survival increased, significant efficacy was consistently maintained in patients with grade 2 or greater GVHD14-17. A systematic review and meta-analysis of real-world studies on primary prevention in letermovir was showed in EBMT 2022. A total of 48 real-world observational studies were included, and the results showed that the use of CMV primary prevention was effective in reducing the overall risk of CMV performance (including CMV reactivation, cs-CMV infection and CMV disease), all-cause mortality and non-relapse mortality at day 200 in adult HSCT recipients. At 100 days follow-up, CMV reactivation decreased by 87%, meanwhile clinically significant CMV infection by 91%, CMV disease decreased by 69%, CMV-related hospitalization decreased by 94%, and GVHD decreased by 48%18. Letermovir has achieved excellent therapeutic benefits globally but is still in its infancy in China. Letermovir obtained an implied license for a clinical trial in June 2020, and in November 2020, Letermovir submitted and accepted four new drug marketing applications in China, including injection and tablet formulations. On December 31, 2021, the China National Medical Products Administration (NMPA) approved letermovir for cytomegalovirus (CMV) seropositive adult recipients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) [R+] prevention of cytomegalovirus infection and cytomegalovirus disease. The commercial launch of letermovir is estimated to be in August 2022. Since the seropositive rate of CMV in the Chinese population is over 90%, it is not enough to judge whether CMV prevention is necessary depending on serology. In the past few years, with the increased number of only children in China, haploidentical stem cell transplantation (haplo-SCT) has been showing a steady expanding trend in China. Most hospitals' pretreatment methods use the Beijing protocol (including ATG) rather than post-transplant cyclophosphamide method to prevent GVHD, which also greatly increases the risk of CMV. To our knowledge, there is little published data focused on the efficacy of CMV prophylaxis for patients undergoing the haplo-SCT in China. A "real-life" evaluation of the new drug in terms of efficacy, emergence of resistance, tolerance related to CMV infection, is useful to propose recommendations on management strategies. Therefore, we would like to conduct a prospective observation study of CMV surveillance in haplo-SCT patients receiving letermovir prophylaxis in China, to evaluate the potential real-life effect of letermovir on efficacy, drug resistance emergence, tolerability, and CMV infection-related morbidity and mortality. This work contributes to recommendations regarding CMV management strategies, especially for patients at highest risk, i.e., CMV R+ haploidentical transplant recipients.
