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.
This is an ongoing Phase 2, open-label, single-center, non-randomized study of sintilimab (one anti-PD-1 antibody same as nivolumab approved in China) plus bevacizumab administered in a low dosage schedule in adult (≥ 18 years) participants with a clinical relapse or circulating tumor DNA (ctDNA)-level relapse of Oligodendroglioma(WHO III). This study has three non-comparative study groups. Cohort 1 and Cohort 2 will receive the same study drug sintilimab 200mg and bevacizumab 3mg/kg every 3 weeks. Cohort 3 will take only standard treatment. A stringent three-step non-randomized process will be used to assign participants to one of the study groups. Neither participants nor doctors but the researcher can choose which group participants are in. No one knows if one study group is better or worse than the other. 80 total participants are expected to participate in this study (30 participants in Cohort 1 and Cohort 2). Grouping process: After enrollment, under the standard of care, participants will receive regular tumor in situ fluid (fluid within the surgical cavity, TISF) sampling for ctDNA analysis and recceive regular MRI. The researcher will study the TISF ctDNA and imaging dynamics to determine whether the tumor reaches to ctDNA-level (Cohort 1) or clinical relapse (Cohort 2). At the first step, all timely identified as ctDNA-level relapse tumors will be assigned into the Cohort 1 and receive the study drug immediately, those failed to be timely identified will be assigned into the Cohort 2 and receive the study drug after the clinical relapse. At the second step, once Cohort 1 or Cohort 2 reaches the target number, the new participants will be all assigned into the other Cohort. In the third step, if no CTDNA-level or clinical relapse was observed within 60 months after surgery, patients were assigned to Cohort 3 and further analyzed for prognostic biomarkers compared with Cohort 1 and Cohort 2.
To compare down sizing strategy versus annular sizing strategy technique (control group) in Type 0 bicuspid aortic stenosis (AS) patients undergoing transcatheter aortic valve replacement (TAVR) with self-expanding valves (SEVs): a randomized superiority trial
To evaluate the efficacy and safety of tislelizumab combined with concurrent chemoradiotherapy in first-line treatment of stage IIIC2 cervical cancer.
Surgeons are increasingly confronted by patients on long-term low-dose acetylsalicylic acid (ASA). However, the perioperative management of these patients undergo non-cardiac surgery has not yet been clear. This single- arm study was to evaluate the safety of continuous use of ASA in the perioperative period in routine minimally thoracic surgery.
The current study is to investigate the safety and efficacy of fruquintinib combined with HAIC in patients with advanced colorectal liver metastases who have failed second-line systemic standard treatment, in order to provide more survival opportunities for the second progression of advanced colorectal liver metastases.
Through a scientific and standardized multicenter, randomized, and controlled study method, the investigators evaluated the clinical efficacy and safety of acupuncture in the treatment of breast cancer-related insomnia, with a view to providing a reliable theoretical basis for the treatment of breast cancer-related insomnia with acupuncture.
Autologous hematopoietic stem cell transplantation is one of the effective means of lymphoma treatment, but patients who receive transplantation in the absence of sufficient stem cell numbers have a delay in stem cell engraftment and a markedly increased risk of infection and emergence. Plerixafor injection is a strong and specific antagonist of CXCR4. It can rapidly mobilize stem cells from bone marrow into peripheral blood circulation by blocking the combination of SDF1 and CXCR4. Studies have shown that the simultaneous use of plerixafor injection and G-CSF can collect more hematopoietic stem cells in a certain period of time than cancer patients who use G-CSF alone. This multicenter, open-label, single-arm study was designed to evaluate the efficacy and safety of plerixafor injection for hematopoietic stem cell mobilization in poorly mobilized lymphoma patients.
Objectives 2.1 Primary objectives 1) To observe and compare incidence and severity of aGVHD and cGVHD between the two arms within 2 years after transplantation. 2) To observe and compare the engraftment rate between the two arms. 3) To observe and compare the incidence of infections between the two arms. 2.2 Secondary objectives 1. To conduct pharmacogenomic assay in CD20 arm(treatment arm) before conditioning and monitor plasma concentration of CD20 dynamically（7d、14d、28d、56d、91d）. 2. To monitor levels of B cells in peripheral blood dynamically (+90d、+180d、+270d、+360d、+450d、+540d、+630d、+720d) in all patients. 3. To observe and compare the incidence of PTLD between the two arms. 4. To observe and compare immunoglobulin levels after transplantation in all patients. 5. To evaluate transplant-related mortality. 6. To evaluate the effect on hematopoietic reconstruction.
The purpose of this clinical trial is to evaluate the long-term efficacy and safety of low-dose oral corticosteroids combined with cyclophosphamide therapy and low-dose corticosteroids monotherapy, on a background of maximal RAS inhibitor therapy, for IgA nephropathy with stage 3 or 4 chronic kidney disease.
This study aimed to analyze the safety of 90-min intravenous rapid infusion of obinutuzumab in patients with B-cell non-Hodgkin's lymphoma and to provide evidence for the applicability of rapid infusion regimens in chemotherapy in China.
