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.
Chronic obstructive pulmonary disease (COPD) and bronchiectasis are common chronic respiratory diseases in China. COPD is characterized by irreversible lung function decline due to airway inflammation, emphysema and alveolar destruction. Bronchiectasis is characterized by permanent bronchiectasis, its main clinical symptoms are cough, dyspnea, hemoptysis and recurrent respiratory tract infections. The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Airway microbiota, whose alterations play an important role in the occurrence and development of bronchiectasis, form a complex ecosystem interacted with host cells and various biotic and abiotic factors in the microenvironment. Additionally, mounting evidence suggests that the airway microbiome is associated with COPD phenotypes and endotypes, and that dysbiosis contributes to airway inflammation. However, the mechanisms remain poorly understood, owing to limited knowledge of microbial functional properties, metabolic activities and cross-talk with the host immune system. The investigators aim to collect sputum specimen and perform multi-omic analysis on patients with COPD and bronchiectasis in seven clinical centres in China.
Collection of ctDNA and TCR data to predict the efficacy and prognosis of brain radiotherapy in patients with brain metastases from non-small cell lung cancer (NSCLC) in a comprehensive manner
TQB2102 is an antibody-drug conjugate comprised of a humanised antibody against Human Epidermal Growth Factor Receptor 2 (HER2), a enzyme-cleavable linker, and a topoisomerase I inhibitor payload, which combine the ability of antibodies to specifically target tumour cells with the highly potent killing activity of drugs with payloads too toxic for systemic administration. This is a phase I study to evaluate the safety, tolerability and effectiveness of TQB102 injection in subjects with advanced malignancies.
This study aim to find out metabolic molecules in blood and urine which could identify high risk of advanced fibrosis in MAFLD patients via NMR-based metabolic profiling.
Preclinical data support the investigation of PARP inhibitors in other neoplasms exhibiting homologous recombination deficiency (HRD) as monotherapy as well as in combination with chemotherapy. However，in colorectal cancer (CRC), the role of HRD alterations is mostly unknown. This study aims to explore the the Efficacy and Safety of Fluzoparib combined with Irinotecan in the Second-line treatment of HRD alterations metastatic colorectal cancer.
This is a multicenter, nonrandomized, open-label, parallel controlled Phase I clinical study to evaluate the Pharmacokinetics, Safety and Tolerability of SIM0417 combined with ritonavir after a single dose in subjects with mild and moderate renal impairment, moderate hepatic impairment, normal renal function, and normal hepatic function. It is divided into Part A (subjects with mild/moderate renal impairment and subjects with normal renal function) and Part B (subjects with moderate hepatic impairment and subjects with normal hepatic function).
In order to solve the bottleneck problems of"zero balance displacement"and"large variation of breastmilk"in the study of iodine EAR of pregnant women, lactating women and infants, firstly, this study intends to clarify the rate of metabolism and distribution of iodine during pregnancy by 125I tracer, SPECT/CT in vivo small animal imaging and γ counting study. Then, the iodine balance study in rats was conducted to verify the degree of "zero balance value displacement"caused by the difference of iodine absorption and store in different organs and tissues under different iodine exposure levels, so as to determine the iodine selection conditions of subjects in the population experiment. To determine the EAR of pregnant women by optimizing the population iodine balance experiment. Secondly, we proposed to study the regulatory mechanism of NIS and Pendrin in the mammary gland of lactating rats under different iodine nutrition levels to clarify the range of breastmilk iodine compensation. Mammary cell experiments intend to clarify the mutual regulations of iodine nutrition, oestrogen, and NIS and Pendrin. Based on the results of animal and cellular experiments, and the effect of genetic, oestrogen and iodine status were considered, a cross-sectional study of lactating women was conducted to determine the normal reference range of breastmilk iodine after screening out the people with abnormal indicators. This study will solve the bottleneck problems and difficulties in the iodine RNI research for pregnant women, lactating women and infants, found the iodine nutritional compensatory mechanism under special physiology, and provide the scientific basis for obtaining the accurate EAR basic data and the revision of iodine DRIs.
The purpose of this study was to explore the relationship between early myocardial injury caused by tumor drug therapy and intestinal microbial structure changes by echocardiographic two-dimensional speckle tracking technique and intestinal microflora structure detection. The investigators will also explore prevention and treatment through randomized controlled trials to initiate early intervention before clinical symptoms appear.
To explore the short-term and long-term outcomes of fluorescence laparoscopic navigation D2 lymph node dissection for colorectal cancer surgery by comparing it with D3 lymph node dissection.
Ibuprofen and Diphenhydramine Hydrochloride Modified-Release Tablets were randomized, open, two-cycle Comparative pharmacokinetic test under double crossover and fasting condition. Main objective: Ibuprofen and Diphenhydramine Hydrochloride Modified-Release Tablets developed by Overseas Pharmaceuticals, Ltd.(Specification: each tablet containing ibuprofen 400 mg, Phenhenhydramine hydrochloride 50 mg) is the test preparation, JOHNSON & JOHNSON CONSUMER INC. Production (trade name: Motrin IB®, Specification: 200 mg) for comparative drug product 1, JOHNSON & JOHNSON CONSUMER INC. Hydrodramine hydrochloride (trade name: Benadryl®, Specification: 25 mg) for comparative formulation 2, In the fasting state, To investigate the pharmacokinetic parameters in healthy Chinese subjects of 1 and 2, And were compared. Secondary objective: To evaluate the safety of a single oral administration of Ibuprofen and Diphenhydramine Hydrochloride Modified-Release Tablets and reference 1 and reference 2 diphenhydramine hydrochloride tablets in fasting conditions in healthy Chinese subjects.
