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.
For patients with HER2-positive early-stage breast cancer, NCCN guidelines recommend chemotherapy plus targeted therapy as the standard adjuvant treatment for patients with tumors larger than 1 cm or lymph node-positive. The APT study enrolled patients with stage I HER2-positive breast cancer and has confirmed the efficacy and safety of intravenous chemotherapy combined with targeted therapy, but only 2.2% of the patients enrolled in microinvasion are enrolled, and there is a lack of large sample size data to provide a treatment reference for these patients. In order to further explore the optimal strategy for adjuvant therapy in this type of patient, we designed a new clinical trial to evaluate the efficacy and safety of oral capecitabine plus pyrotinib as adjuvant therapy in previous retrospective studies.
ustekinumab (UST) can effectively induce and maintain clinical remission and mucosal healing of Crohn's disease (CD), but some patients still have poor response. Dose optimization is an effective way to improve the response rate of UST, and re-intravenous induction is a common way of optimization. For patients with secondary loss of response, about half of the patients can re-respond after dose optimization. We plan to use CDST-UST to stratify the response level of patients before treatment, select patients with poor response, and initially give multiple intravenous therapy as an intensive induction therapy strategy, so as to improve the response rate of these patients and achieve individualized treatment.
The purpose of this study is to determine if Jaktinib is safe and effective in participants with active ankylosing spondylitis.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, efficacy and safety study of Jaktinib in subjects with active Ankylosing Spondylitis(AS).
The Efficacy and Safety of Dezocine Pretreatment for Pain Relief in Acne Scar Treatment of Fractional CO2 Laser
This trial is a multi-center phase III clinical trial. The purpose of this trial is to explore whether 2 cycles induction chemotherapy combined with concurrent chemoradiotherapy is not inferior to 3 cycles induction chemotherapy combined with concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma.
Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery: A Multicenter, Prospective, and Cohort Study
This is a non-randomized, open-label, single-dose study. The aim of this study is to evaluate the safety and efficacy of the treatment with lentiviral vector encoding βA-T87Q-globin gene transduced autologous hematopoietic stem cells in subjects with β-thalassemia major.
This study evaluated the safety and efficacy of SPH4336 in combination with endocrine therapy in the treatment of locally advanced or metastatic breast cancer that progressed on CDK4/6 inhibitor combined with endocrine therapy.
This is a self-controlled cohort study to evaluate the efficacy and safety of comprehensive treatment in patients with inflammation-associated rapidly-progressive coronary artery disease (IR-CAD) by comparing the study endpoints before treatment with those after treatment in the same group of patients.
