Clinical trials

This is a prospective, single-center, open-label clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of inhaled BMD003 (CFTR mRNA) in Chinese patients aged 12 years and above with cystic fibrosis (CF) following multiple administrations. Additionally, the study aims to explore the pharmacokinetic characteristics, immunogenicity, and relevant biomarkers of the drug. The study adopts a multiple-dose escalation design. Eligible patients will be sequentially enrolled into different cohorts, and the next cohort may receive a higher dose only after the safety data review of the previous dose cohort is completed. The entire study consists of four phases: screening period, safety observation period, continuous treatment period, and long-term follow-up period. Participants will receive nebulized inhalation of the study drug at the specified frequency. During the study, blood, sputum samples, and nasal swabs will be collected at designated time points for pharmacokinetic, immunogenicity, cytokine, and other related detections. Moreover, lung function tests, chest imaging, electrocardiograms, sweat chloride concentration tests, and other examinations will be performed at each visit. Meanwhile, the Cystic Fibrosis Questionnaire-Revised (CFQ-R) will be used to assess the patients' health-related quality of life, so as to comprehensively evaluate the safety and efficacy of the study drug. Adverse events will be closely monitored and recorded throughout the study. The safety of the study drug will be comprehensively evaluated by summarizing various safety indicators such as adverse events and laboratory tests. All statistical analyses will be performed using professional statistical software, and descriptive statistical methods will be employed to analyze the safety, efficacy, pharmacokinetic, and other related data of the study drug. The total duration of this study is 1 year, which is intended to provide a basis for the selection of the recommended dose for Phase Ⅱ clinical trials.

This prospective, non-randomized, concurrent parallel-controlled study will evaluate treatment response and resistance mechanisms in patients with pancreatic neuroendocrine tumors with liver metastases (pNET-LM) receiving second-line systemic therapy after failure of first-line treatment. Eligible patients will receive either lenvatinib combined with chemotherapy or chemotherapy alone according to the study protocol and clinical treatment strategy. The clinical efficacy and safety of the two treatment strategies will be evaluated using objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events. Peripheral blood samples will be collected before treatment, during early treatment, and at disease progression. Circulating cell-free DNA (cfDNA) and peripheral blood mononuclear cells (PBMCs) will be analyzed to investigate molecular and immune changes associated with treatment response, primary resistance, and acquired resistance. The study aims to identify potential biomarkers for predicting treatment response and to improve understanding of resistance mechanisms in pNET-LM.

This is a first in human study that will assess the safety, pharmacokinetics, biodistribution and diagnostic performance of \[18F\]FIDT-10b (fluorine-18 labeled FIDT-10b), a positron emission tomography (PET) agent. This agent has the potential to specifically identify the involved myocardium of patients with transthyretin cardiac amyloidosis (ATTR-CA).

This prospective study will evaluate the safety, biodistribution, dosimetry, and imaging performance of 68Ga-NYM215 PET/CT in patients with neuroendocrine neoplasms. An head-to-head comparison with 68Ga-DOTATATE PET/CT will assess the diagnostic performance of 68Ga-NYM215 PET/CT at both the patient and lesion levels.

This was a single center, prospective cohort study that is evaluating the ability of beta-amyloid dynamic PET/CT to detect potential therapeutic changes in subjects under treatment for AL-CA after one year had elapsed since their baseline beta-amyloid PET/CT. Demographic, clinical and PET imaging data were collected to characterize potential changes since their baseline scans.

The goal of this clinical trial is to learn whether new adjuvant radiotherapy with gross tumor volume(GTV) escalated to 58.75 Gy can improve complete response (CR) rates compared with GTV dose of 50 Gy in adult patients (18-79 years) with locally advanced rectal adenocarcinoma (T3-T4/N+, M0) located ≤10 cm from the anal verge.The main questions it aims to answer are: 1. Does GTV simultaneously boost to 58.75 Gy/25f increase complete response (pCR or cCR) compared with 50 Gy/25f? 2. How do the two regimens differ in terms of progression-free survival (PFS), pelvic local control (LC), tumor regression grade (TRG), organ preservation, and treatment-related toxicity? Researchers will compare GTV 58.75 Gy/25f (experimental arm) versus GTV 50 Gy/25f (control arm) to see if dose escalation improves tumor response rate. Participants will: 1. Receive neoadjuvant radiotherapy with one of the two PGTV dose escalated regimens (with concurrent chemotherapy: oral capecitabine or XELOX). 2. Undergo restaging with imaging and clinical assessment before surgery or observation. 3. Proceed to total mesorectal excision (TME), local excision, or "watch-and-wait" strategy depending on treatment response and patient preference. 4. Be followed regularly with clinical exams, imaging, endoscopy, and laboratory tests to assess efficacy, safety, and long-term outcomes.

This study aims to conduct a randomized controlled trial to compare the efficacy and safety of Baricitinib and Adalimumab (ADA) in the treatment of refractory intestinal Behçet's Syndrome (BS). The objective is to demonstrate if Baricitinib is non-inferior to ADA in controlling BS inflammation, reducing BS recurrence， alleviating gastrointestinal symptoms and promoting intestinal mucosal healing.

The investigators plan to conduct a 68Ga-DOTA-dPNE PET/CT imaging study in breast cancer patients to observe the binding of the tracer to tumor lesions and evaluate CD73 expression. As part of the study design, a subset of patients will initially undergo dynamic PET/CT imaging to evaluate the safety profile and pharmacokinetic distribution of the radiotracer in vivo. Subsequently, static PET/CT imaging will be performed on additional patients to assess the diagnostic effectiveness of 68Ga-DOTA-dPNE. Imaging results will be correlated with relevant clinical indicators to evaluate the potential of this tracer in diagnosing breast cancer, guiding therapeutic decisions, and predicting responses to targeted therapies.

This is a single-center, randomized controlled study. The aim of this study is to compare the impact of left bundle branch area pacing versus traditional right ventricular pacing on the incidence of atrial fibrillation in patients with atrioventricular block.

This study aims to evaluate whether digital cognitive training and/or PCSK9 inhibitor-enhanced lipid-lowering therapy on top of moderate-intensity statin can improve cognitive function in patients with intracranial atherosclerosis (ICAS). ICAS is a common cause of stroke and is also linked to thinking and memory problems. The study will enroll 440 adults aged 55-80 years who have 50-99% narrowing of an intracranial artery, subjective memory complaints, and LDL cholesterol ≥1.8 mmol/L, but who are not demented. Participants will be randomly assigned to one of four groups in a 2×2 factorial, parallel-group design: No cognitive training + moderate-intensity statin therapy Cognitive training + moderate-intensity statin therapy No cognitive training + moderate-intensity statin plus PCSK9 inhibitor Cognitive training + moderate-intensity statin plus PCSK9 inhibitor Cognitive training consists of 30 minutes of tablet-based exercises, 5 days per week for 24 weeks (first 12 weeks as the intensive phase, followed by 12 weeks continuation phase). The PCSK9 inhibitor (Recaticimab) is administered subcutaneously according to the product label, on top of moderate-intensity statin. The main outcome is change in a composite cognitive score from baseline to 24 weeks. Secondary outcomes include changes in specific cognitive domains, serum LDL-C, MRI markers of brain structure and function, and safety measures. The study is multicenter, open-label with blinded outcome assessment, and is conducted under the approval of the ethics committee of Peking Union Medical College Hospital.

This is a prospective single-arm phase II study, with the purpose of evaluating the efficiency of ZR-MTX regimen (Rituximab, Zanubrutinib and methotrexate) combined with intravitreal methotrexate, then followed by minimal residual disease directed Zanubrutinib maintenance in newly-diagnosed primary intraocular lymphoma. The primary endpoint of this study is progression-free survival (PFS).

This clinical research evaluates a new PET/CT imaging agent, \[68Ga\]Ga-HBED-CC-PEG6-exendin-4, for localizing insulinoma, a rare pancreatic tumor that causes severe low blood sugar. Insulinomas are often small and hard to detect with regular CT, ultrasound or standard PET scans. This new tracer targets GLP1R, a protein highly expressed on insulinoma cells, with polyethylene glycol (PEG6) modification to improve tumor uptake and image contrast compared with the earlier similar agent \[68Ga\]Ga-HBED-CC-exendin-4. The investigators plan to enroll 20 adult patients suspected of or confirmed to have insulinoma. All participants will receive two free PET/CT scans within one week: one with the new PEG6-modified tracer and one with the original tracer. The first 3 participants will also get dynamic PET scanning to analyze drug distribution and radiation dose in the human body. Within one month after imaging, patients will undergo surgery or biopsy to get pathological results, which serve as the gold standard to calculate and compare the diagnostic accuracy of the two tracers. All imaging procedures follow standard clinical protocols with safe, low radiation doses within national diagnostic limits. Minor possible risks include slight pain or mild allergic reaction at the injection site; rare side effects related to exendin-4 may occur at a rate below 5%, and the research team has full emergency management measures ready. Participants can withdraw from the study at any time without penalty. All scan fees are covered by the research project, and each subject will receive a formal imaging report for clinical reference. The findings of this trial will help develop a more accurate imaging tool to precisely locate insulinoma and guide surgical treatment.

Carbapenem-resistant organisms (CRO) pose a critical threat to global public health, and hospitals serve as major epicenters for their emergence and spread. Traditional clinical infection surveillance often detects CRO outbreaks only after infections have already occurred, missing the window for early intervention. Wastewater-based epidemiology has demonstrated its early warning potential during the COVID-19 pandemic and is increasingly recognized as a promising tool for antimicrobial resistance surveillance. Our preliminary 22-day pilot study at Peking Union Medical College Hospital revealed two distinct antimicrobial resistance gene (ARG) dynamics patterns across different hospital areas: the Internal Medicine Ward exhibited a "chronic resistance background" with persistently high abundance of carbapenemase genes (IMP/GES types \>5,000 ppm), while the Emergency/Fever Clinic showed "acute pulse outbreaks" characterized by transient 50- to 200-fold surges of mcr-3 and QnrVC genes. These findings suggest that hospital functional areas have fundamentally different ARG profiles with unique temporal signatures. This prospective observational cohort study aims to establish a wastewater-based early warning system for hospital-acquired CRO outbreaks by conducting longitudinal monitoring across four key functional areas: Outpatient Building, Internal Medicine Ward, Surgical Ward, and Emergency/Fever Clinic at Peking Union Medical College Hospital over a 6- to 9-month period. Twenty-four-hour flow-proportional composite wastewater samples will be collected daily using automatic samplers. Laboratory analyses include ARG large-panel testing (300+ subtypes, daily), metagenomic sequencing (weekly, plus pulse-triggered intensified sampling), and viable bacterial culture with whole-genome sequencing of key isolates. Concurrently, we will collect de-identified clinical CRO isolates and antibiotic consumption data (Defined Daily Doses) from the corresponding hospital buildings. Multidimensional association analyses will be performed using cross-correlation function analysis, Granger causality tests, and cgMLST-based genomic comparisons to determine the lead time of wastewater ARG signals ahead of clinical CRO diagnoses and to provide direct evidence of clonal homology between wastewater and clinical isolates. An early warning model will be constructed using dynamic thresholds (moving average + 2SD/3SD) and machine learning algorithms. This study integrates environmental, clinical, and pharmaceutical data following the One Health framework. By establishing a replicable building-level wastewater resistome surveillance protocol, this research is expected to provide hospitals with a proactive tool for early CRO outbreak detection, enabling timely infection prevention and control measures. All clinical data will be de-identified, and the study has been designed to pose no greater than minimal risk to patients, with a waiver of informed consent sought in accordance with relevant ethical regulations.

This is a very safe and beneficial clinical study. We hope to obtain near-real airway anatomical parameters of patients before surgery through airway three-dimensional reconstruction technology, to assist anesthesiologists in matching the most suitable double-lumen bronchial tube size for each patient, thereby reducing the rate of intubation failure and the occurrence of perioperative adverse events to a certain extent.

This study is a single center cohort study to access the anti-tumor efficacy, safety and tolerability of DZD9008 in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) sensitizing mutations and EGFR uncommon mutations who have progressed following standard TKI therapy, and in treatment naive patients with NSCLC harboring EGFR Exon20 insertion mutation and EGFR sensitizing mutations.

Anemia is a common condition, but it often goes undiagnosed because confirming it requires a venous blood test. This study looks at whether a commercially available wrist-worn smartwatch can help identify people who may have anemia, without taking blood. The watch continuously records several types of physiological signals, including photoplethysmography (a light-based measure of blood flow), movement, heart rate, blood oxygen saturation, and heart rate variability. Researchers will use these signals to build a computer model that sorts participants into two groups: likely to have anemia, or unlikely to have anemia. About 400 adults between 18 and 80 years of age will take part at one hospital in Beijing, China. Both patients with anemia and people with normal hemoglobin levels will be included. Each participant will wear the watch and also have a standard venous blood test to measure hemoglobin, which serves as the reference for comparison. Data from the first 250 participants will be used to develop the model. Data from the next 150 participants will be used to test how well the model works in a separate group. The main question is how accurately the watch-based result matches the blood test result.

This study aimed to evaluate the efficacy and safety of Lanoracopan Hydrochloride in the treatment of Paroxysmal Nocturnal Hemoglobinuria (PNH)

This is a prospective, single-center phase I/II study, with the purpose of evaluating the efficiency of golidocitinib combined with chidamide in patients with systemically-treated cutaneous T-cell lymphoma. The primary endpoint of the phase I study was to determine the recommended phase II dose (RP2D), while the primary endpoint of the phase II study was the objective response rate (ORR). Secondary endpoints included the complete response (CR) rate, progression-free survival (PFS), duration of response (DOR), overall survival (OS), and safety profile.

Branch atheromatous disease (BAD) is a distinct subtype of ischemic stroke that is particularly prevalent among Chinese and other Asian populations. Patients with BAD are prone to early neurological deterioration and poor functional outcomes, and BAD is increasingly recognized as an independent disease entity. However, the association between BAD and cognitive impairment remains unclear. This nationwide, multicenter, prospective observational study will prospectively collect epidemiological, clinical, neuroimaging, functional, and cognitive outcome data from patients with BAD. The study aims to investigate the occurrence of cognitive impairment after BAD and identify the clinical and neuroimaging characteristics associated with cognitive impairment. In particular, the relationship between early neurological deterioration (END) and cognitive impairment will be investigated. As an exploratory objective, this study will further explore the potential brain network mechanisms underlying cognitive impairment associated with END events.

This study aims to investigate the feasibility of utilizing the SurgDiff surgical difficulty prediction model to assist surgeons in formulating precise surgical plans.
