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 a single arm study to evaluate the efficacy and safety of BCMA-targeted prime CAR-T cells therapy for patients with relapsed/refractory Multiple Myeloma.
The purpose of this study is to evaluate the safety of linear and macrocyclic gadolinium-based contrast agents for patients with mild to moderate renal insufficiency. The study will compare the incidence of adverse events of gadodiamide and gadoteric Acid Meglumine Salt for patients with mild to moderate renal insufficiency undergoing enhanced magnetic resonance imaging.
This is a prospective, randomized, controlled study to evaluate the diagnostic yield and safety of three-dimensionally printed navigational template in percutaneous transthoracic lung biopsy.
In this protocol, the investigators present methods and preliminary results from the PLATFORM-CVD Study, an EHR-based multicenter cohort. This study will focus on assessing the distribution of major cerebrovascular diseases, determining the risk factors associated with disease incidence and worse in-hospital outcomes, as well as describing the quality of care. Data from this cohort will be used to develop suitable prediction models for cerebrovascular diseases using real-world data and to understand how outcomes for cerebrovascular diseases would change with quality improvement interventions.
The study aims to estimate the efficacy and safety of systemic therapy sequenced radical surgery in treating patients with synchronous isolated para-aortic lymph node metastasis of colorectal cancer.
This study will evaluate the safety, pharmacokinetics, and efficacy of alectinib in children and adolescents with ALK fusion-positive solid or CNS tumors for whom prior treatment has proven to be ineffective or for whom there is no satisfactory standard treatment available.
At present, there are few studies on the side effects of chemotherapy in breast cancer patients at high altitude area, and there are no studies on the relationship between oxygen inhalation and fatigue after chemotherapy in breast cancer patients at high altitude. The investigators intend to explore whether oxygen inhalation can improve fatigue at high altitude through this prospective randomized study. In our study, a single center, open-label, randomized phase 2 clinical trial will conduct to investigate whether oxygen inhalation during chemotherapy can improve chemotherapy-related fatigue in patients with breast cancer. The effects of oxygen inhalation on side effects of chemotherapy such as Cancer related fatigue (CRF) were observed. The investigators intend to explore whether oxygen therapy can improve fatigue at high altitude through this prospective randomized study. The investigators enrolled breast cancer patients before chemotherapy. The investigators will use the checklist individual strength(CIS) and the brief fatigue inventory (BFI) to evaluate the fatigue status of patients, and extract the blood of patients for evaluate blood pro-inflammatory cytokines IL-1 β, IL-6, C-reactive protein (CRP), transforming growth factor (TGF-β), soluble tumor necrosis factor (TNF) receptor II (sTNF-RII), inducible factor-1(HIF-1), Hypoxia inducible factor-2(HIF-2)in the plasma.
An open-label, dose-escalation, phase I clinical study to evaluate the safety and tolerability of JS004 injection in the patients with advanced solid tumors who have failure in standard of care and are unable to tolerate standard of care and/or have no available standard of care. The study is divided into screening period, treatment period, and follow-up period. 1. Screening period: Subjects will be included in the screening period after signing the informed consent form (ICF). The screening period is up to 28 days, subjects will enter the study treatment period if they meet all the inclusion criteria and none of exclusion criterion. 2. Treatment period: Subjects will be allocated to the designated dose group to receive corresponding treatment in accordance with the progress of study. Subjects in dose escalation phase will receive DLT observation at first, and upon completion of DLT observation, the subjects will continue their administration at the original dose if they are tolerated as judged by investigator, until progression of disease, intolerable toxicity or other reasons specified in the protocol. Subjects in the dose extension phase receive appropriate study treatment until disease progression, intolerance of toxicity, or other causes specified in the protocol occur. Response evaluation criteria in solid tumors (RECIST v1.1) will be used for efficacy evaluation every 9 weeks (±7 days) in the first year and every 12 weeks (±7 days) in the 2nd year and thereafter. 3. Follow-up period: A safety follow-up visit is required 30 days (±7 days) after the last dose of study drug or before the initiation of new antitumor therapy. If the new antitumor therapy has not been initiated, additional safety follow-up should be completed 90 days (±7 days) after the last dose as far as possible.
This study is a multicenter, open-label, multi-cohort phase II clinical trials to evaluate the efficacy and safety of TQB3616 capsules combined with Fulvestrant injection in subjects with HR-positive and HER2-negative advanced and/or metastatic breast cancer, including Cohort 1 and Cohort 2. Each cohort will enroll 30-60 cases.
From January 2010 to December 2014, 150 children with MS-LCH were treated in our hospital following a LCH II (Arm B) based protocol. Treatment was based on a modification of the LCH-II (Arm B) based protocol. However, the continuation treatment was extended to 56 weeks and etoposide was omitted from the continuation treatment. For the 59 patients with RO involvement (RO+) (the lungs are not considered a RO in the current study), the rapid response rate (week 6) was 61.0% and the 3-year overall survival (OS) 73.4±5.9%. Rapid responders had a better 3-year survival rate than poor responders (90.9±5.0% vs. 45.7±11.0%, P<0.001). The 3-year OS in the current study is 10~20% lower than the rates reported by Gadner et al. and Morimoto et al.. We have not yet adopted effective salvage therapies for RO+ patients with recurrent disease. During the time of this study, cladribine was unavailable. Second-line therapy for non-responders or patients with disease reactivation was individualized treatment based on the physician's experience. An effective salvage therapy is essential for this high-risk group. For 91without RO involvement (RO-), 78 patients (85.7%) were rapid responders at week 6. The 3-year cumulative reactivation rate was 10.7% for RO- patients. No death occurred in this subgroup, with a 3-year OS of 100% in RO- patients. Compared to the LCH II and LCH III trials, the current study had a more intensive initial treatment regimen for RO- patients. However, the addition of etoposide to prednisone and vincristine in the initial therapy did not increase the 6-week response rate for RO- patients (85.7% in this study compared to 83% in the LCH II study and 86% in the LCH III study). Surprisingly, with a relatively intense initial treatment, a relatively low 3-year cumulative reactivation rate was observed in RO- patients in the current study. This result suggests that the initial treatment intensity and duration of continuation therapy both impact disease reactivation. The intensity of induction can affect the degree of disease resolution. Insufficient treatment intensity might lead to late relapse. Similarity to that observed has been in other childhood hematological malignancies. This finding deserves to be tested in prospective clinical trials with long-term follow-up. Cytarabine has been applied for patients with LCH but has never been evaluated in our hospital prospectively. In this study, we administer a cytarabine contained protocol to patients with multisystem involvement with or without risk organs involvement. The treatment results will be compared with our historical studies.
