Clinical trials

This is a single-center, single-arm, open-label clinical study conducted at the Department of Stomatology, Nanjing Drum Tower Hospital. The study aims to evaluate the safety and efficacy of autologous bone marrow-derived mononuclear cells (BMMNCs) combined with a bone graft material (Bio-Oss) for the repair of severe maxillofacial (alveolar/jaw) bone defects caused by inflammation, trauma, or other reasons. Approximately 20 patients aged 18-60 years with severe alveolar bone resorption requiring bone grafting will be enrolled. About 60 mL of autologous bone marrow will be aspirated from the iliac crest, and BMMNCs will be isolated by density-gradient centrifugation under GMP conditions without in vitro expansion. The BMMNCs will be mixed with Bio-Oss bone graft material and implanted into the bone defect, covered with a collagen membrane. Cone-beam CT (CBCT) will be performed postoperatively to assess new bone formation. Follow-up visits are scheduled at 1 week, 1 month, 3 months, and 6 months after surgery. The primary outcome is the new bone volume fraction in the grafted area measured by CBCT. Safety will be assessed by clinical examination of the implantation site and laboratory tests (blood routine, urinalysis, liver and kidney function, blood glucose).

This single-center prospective randomized controlled study will enroll 500 infertile women aged 35 years or older who meet the criteria for fresh day-5 single-blastocyst transfer. Participants will be allocated 1:1 to AI-assisted morphological assessment using EmbryoInsights™ or AI-assisted morphological assessment combined with euploidy prediction using EmbryoInsights™ Plus. The study evaluates whether adding euploidy prediction improves ongoing pregnancy after the first fresh transfer. Secondary outcomes are clinical pregnancy, early miscarriage and live birth. Maternal and infant safety will be monitored.

This is a randomized, noncomparative, open-label, exploratory clinical study designed to evaluate the efficacy and safety of sintilimab in combination with NALIRIFOX or gemcitabine plus cisplatin (GP) as first-line treatment for patients with metastatic biliary tract cancer (BTC) who have not received prior systemic anticancer therapy for metastatic disease. Approximately 54 eligible participants will be randomized in a 1:1 ratio to two treatment groups. Participants in Group A will receive sintilimab in combination with NALIRIFOX, consisting of liposomal irinotecan (II), 5-fluorouracil/leucovorin, and oxaliplatin. Participants in Group B will receive sintilimab in combination with gemcitabine and cisplatin. The primary endpoint is objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety.

This study aims to evaluate the safety and tolerability of SNC116 in treating patients with systemic lupus erythematosus.

A multi-center prospective, open-label, parallel-group randomized controlled trial is conducted to investigate the cognitive-protective efficacy of a novel, diabetes-specific virtual reality (VR)-based cognitive training system integrated with diet management modules, relative to frequency- and duration-matched traditional paper-and-pencil cognitive training, in adults aged 45-80 years with T2DM and amnestic/mixed mild cognitive impairment (MCI). A total of 40 eligible participants are randomly assigned 1:1 to either the intervention group (24 weeks of individualized VR training with dynamic difficulty, 2 sessions/week, 45-60 minutes/session) or the active control group (standardized paper-and-pencil cognitive tasks). All participants maintain stable glucose-lowering regimens for ≥3 months and receive standardized weekly diabetes health education. The primary endpoint is the between-group difference in the change in MoCA total score from baseline to the 24-week follow-up. Secondary endpoints include changes in individual cognitive domains (memory, executive function, attention, processing speed), Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) Score , Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog13) Score , Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) Score, olfactory threshold/identification/recall, brain structural volumes and resting-state functional connectivity (assessed via 3.0T fMRI), glycemic control (HbA1c, fasting/postprandial glucose), lipid profile, body composition, sleep quality, anxiety and depressive symptoms, and diabetes self-management behaviors. The safety and participant adherence to the VR intervention are also systematically monitored.

The LIGHT-COG study is a 76-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial evaluating the efficacy and safety of mazdutide in 420 participants with type 2 diabetes (T2D) and early-stage cognitive impairment, defined as mild cognitive impairment (MCI) or mild dementia. Participants are randomized 1:1 to receive once-weekly subcutaneous mazdutide, with dose escalation according to the protocol, or matching placebo, in addition to background glucose-lowering therapy. The primary objective is to determine whether 76 weeks of mazdutide treatment can slow cognitive and functional decline compared with placebo in this population.

This study investigates whether metformin, compared with placebo, improves cardiac function in patients after Left Ventricular Assist Device (LVAD) implantation. Metformin is a widely used oral medication for type 2 diabetes, but emerging evidence suggests it may have beneficial effects on cardiac metabolism and function independent of its glucose-lowering effects. This is a prospective, multicenter, randomized, double-blind, placebo-controlled trial. A total of 108patients undergoing LVAD implantation will be enrolled from 5 centers in China. Eligible participants will be randomly assigned in a 1:1 ratio to receive either metformin or placebo for 12 months. The primary outcome is the incidence of Full Responder at 12 months post-implantation. A Full Responder is defined as meeting all of the following four criteria: (1) left ventricular ejection fraction (LVEF) ≥40% and left ventricular end-diastolic diameter (LVEDD) ≤6.0 cm (Utah-Inova Responder criteria); (2) soluble ST2 (sST2) ≤100 ng/mL at both 6 months and 12 months post-implantation; (3) absolute value of left ventricular global longitudinal strain (GLS) ≥12% at 12 months post-implantation. Secondary outcomes include clinical events, cardiac function status, blood biomarker results, global functional status and quality of life, medication safety, and exploratory measures. Clinical events assessed up to 24 months post-implantation include: heart failure rehospitalization rate, all-cause mortality, LVAD explantation rate, cardiovascular mortality, major bleeding, cardiac structural damage, thromboembolic events, systemic inflammatory dissemination, sepsis, and other serious adverse events. Cardiac function status is evaluated by echocardiographic parameters (LVEF, LVEDD, GLS) and hemodynamic measures. Blood biomarkers include sST2, NT-proBNP, cardiac troponin, and inflammatory cytokines. Global functional status and quality of life are measured using the 6-minute walk test (6MWT), peak oxygen consumption (VO₂max), and the Kansas City Cardiomyopathy Questionnaire (KCCQ). Safety outcomes include the incidence and severity of adverse events, serious adverse events, and adverse events of special interest. Exploratory outcomes include pre-implantation right ventricular myocardial biopsy (obtained only when clinically indicated for temporary pacemaker lead placement) to assess insulin receptor substrate (IRS)/Akt phosphorylation, G6PD activity, NADPH/NADP⁺ ratio, and oxidative stress markers (malondialdehyde, 4-hydroxynonenal). The study aims to provide evidence on whether adjunctive metformin therapy can improve post-LVAD cardiac outcomes and reduce adverse clinical events.

This study aims to develop and validate a clinical prediction model for the risk of head and neck cancerous lesions using deep learning combined with AI algorithms, based on multi-center clinical data.

This is a prospective, single-arm, exploratory interventional study designed to evaluate the efficacy and safety of liposomal irinotecan (II) plus fluorouracil/leucovorin (5-FU/LV) and sintilimab with sequential stereotactic body radiation therapy (SBRT) as first-line treatment for patients with unresectable locally advanced biliary tract cancer (BTC) who have not received prior systemic anticancer therapy for their current disease. Approximately 31 participants will be enrolled. Participants will receive liposomal irinotecan (II), 5-FU/LV, and sintilimab. Participants without disease progression after initial systemic treatment will receive sequential SBRT to the primary biliary tract tumor. After eight administrations of chemotherapy (approximately 16 weeks), resectability will be assessed by a multidisciplinary team. Participants considered eligible for surgery will undergo radical surgical resection followed by adjuvant treatment, whereas those who remain unresectable will continue the study treatment until disease progression or another protocol-defined reason for discontinuation. The primary endpoint is objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), surgical conversion rate (SCR), and safety.

Prostate biopsy usually combines magnetic resonance imaging/ultrasound (MRI/US) cognitive fusion targeted biopsy with systematic biopsy. Standard bilateral systematic biopsy requires sampling from both sides of the prostate and may increase the number of biopsy cores, procedural discomfort, procedure time, pathological workload, and biopsy-related complications. This prospective, multicenter, open-label, randomized noninferiority trial will enroll 454 biopsy-naive men with suspected prostate cancer, a unilateral prostate MRI lesion with a highest PI-RADS score of 4 or 5, and prostate-specific antigen levels of 20 ng/mL or lower. Participants will be randomly assigned in a 1:1 ratio to receive transperineal MRI/US cognitive fusion targeted biopsy combined with either a 6-core ipsilateral systematic biopsy or a standard 12-core bilateral systematic biopsy. The primary objective is to determine whether the ipsilateral systematic biopsy strategy is noninferior to the bilateral systematic biopsy strategy for detecting clinically significant prostate cancer, defined as International Society of Urological Pathology Grade Group 2 or higher. The study will also compare overall prostate cancer detection, biopsy core numbers, pain and discomfort, procedure time, pathological workload and costs, urinary symptoms, quality of life, and biopsy-related adverse events and complications through 30 days after biopsy.

This multicenter, randomized, double-blind, placebo-controlled trial evaluates the efficacy and safety of ketorolac in 1,346 patients with Stanford Type A aortic dissection, conducted between 2025 and 2028. Participants will receive either ketorolac (60 mg intramuscularly \[IM\] within 6 hours before surgery and 30 mg im twice daily（at 6:00 AM and 6:00 PM, respectively for two days postoperatively or placebo in addition to standard care. Study outcomes include composite clinical endpoints, postoperative complications, and adverse events, which will be assessed through clinical evaluations, laboratory testing, and imaging studies at predefined intervals up to 90 days. The objective of this trial is to determine whether perioperative administration of ketorolac improves clinical outcomes in this patient population.

Subjective cognitive decline (SCD) is the early diagnosis and treatment window period of Alzheimer's disease (AD), and the identification of SCD individuals who will progress to AD (pSCD) is a research hotspot. Based on olfactory fMRI,previous studies have found that SCD individuals showed damaged entorhinal neural circuits. After follow-up, the incidence of pSCD increased by three times. But,the spatiotemporal characteristics of the entorhinal neural circuits and whether it has the value of individualized prediction and intervention target need to be further studied. Thus, based on multi-center ambispective cohort study at home and abroad, we will (1) build a new paradigm of synchronous fMRI-EEG olfactory task state Oddball experiment, jointly representational similarity analysis, extract spatiotemporal characteristics of neural circuits damage, and discover and verify that the entorhinal neural circuits are vulnerable brain regions; (2) establish the middle fusion model of vulnerable brain region combined with the methods of olfactory task-fMRI activation image generation, functional connectome gradient,etc.; Then, establish late fusion multi-omics multi-task model combined with the new methods of molecularomics such as ultra-deep total proteomics and metabonomics proposed by the research group to accurately identify pSCD; (3) carry out the precise intervention of image-guided "olfactory three-needle" acupuncture with the entorhinal neural circuits as the target. Through clinical RCT research and mouse model, the remodeling mechanism of vulnerable brain regions will be clarified.This project will provide the basis for early diagnosis and treatment of the AD risk population.

This single-centre, prospective observational feasibility and safety study will enrol 190 consecutive adults undergoing elective isolated coronary artery bypass grafting (CABG) at Nanjing Drum Tower Hospital. The study aims to evaluate the feasibility and safety of intraoperative ultrasound for the quantitative assessment of native coronary artery and bypass graft blood flow. Transit-time flow measurement will be performed as part of routine intraoperative graft assessment. Additional ultrasound measurements will be obtained from major native coronary arteries before and after revascularisation and from bypass grafts after restoration of blood flow. The ultrasound findings will be collected for research purposes and will not influence graft revision or other intraoperative clinical decisions. The co-primary outcomes are the participant-level technical success rate of the protocol-defined intraoperative ultrasound assessment and the incidence of adverse events related to the ultrasound device or measurement procedure. Secondary outcomes include agreement between ultrasound and transit-time flow measurements, changes in native coronary artery blood flow after revascularisation, measurement repeatability, and exploratory associations between intraoperative flow parameters and postoperative cardiac function and myocardial injury biomarkers. Participants will be followed for 30 ± 7 days after surgery.

This clinical trial is designed to study an investigational cell therapy called cCTL-GL01 in patients with advanced gastrointestinal cancers (including cancers of the stomach, esophagus, colon, or rectum) that have not responded well to standard treatments. The main goals of this study are to find out: If cCTL-GL01 is safe and what side effects it might cause; How well cCTL-GL01 works to control or shrink tumors.

Prostate cancer patients with high-risk features who undergo radical prostatectomy (RP) are at a significant risk of biochemical recurrence (BCR) and disease progression. While adjuvant androgen deprivation therapy (ADT) with or without radiotherapy is the current standard of care, long-term ADT is associated with substantial adverse effects, including metabolic syndrome, cardiovascular disease, and bone density loss, which negatively impact patients' quality of life. There is an unmet clinical need to optimize adjuvant treatment strategies to improve survival outcomes while minimizing treatment-related toxicity for this high-risk population. Rezvilutamide is a novel, potent, second-generation oral androgen receptor (AR) inhibitor. This prospective, multicenter, single-arm clinical trial aims to evaluate the efficacy and safety of rezvilutamide monotherapy as an adjuvant treatment in patients with localized prostate cancer who have a high risk of recurrence following radical prostatectomy. The study plans to enroll 48 male patients (aged 18-75 years) who have completed radical prostatectomy within 12 weeks, have achieved a postoperative prostate-specific antigen (PSA) level of \< 0.1 ng/mL within 8 weeks, and possess a high recurrence risk defined by a CAPRA-S score of ≥ 6. Eligible patients will receive rezvilutamide monotherapy at a dose of 240 mg orally once daily for 12 cycles (28 days per cycle, totaling 48 weeks). The primary endpoint of the study is the 2-year biochemical progression-free survival (bPFS) rate. Secondary endpoints include event-free survival rate, 5-year bPFS, 5-year metastasis-free survival (MFS), testosterone recovery rate and time at 2 years, overall safety, and health-related quality of life assessed by the FACT-P and EPIC-26 questionnaires. By exploring this monotherapy approach, the study hopes to provide a new, effective, and better-tolerated adjuvant treatment option that can improve the prognosis of high-risk patients post-prostatectomy.

This study will evaluate whether a machine learning-based decision support model, called the Drum Tower Rule, can help surgeons select the lowest instrumented vertebra during corrective surgery for adolescent idiopathic scoliosis. Patients with Lenke type 1 or Lenke type 5 adolescent idiopathic scoliosis who are scheduled for posterior spinal fusion will be randomly assigned to one of two groups. In the model-guided group, surgeons will receive the model-predicted risk of postoperative distal adding-on and a recommendation for lowest instrumented vertebra selection. In the conventional-experience group, surgeons will select the lowest instrumented vertebra according to routine clinical experience and existing surgical principles, without access to the model output. All patients will receive standard posterior spinal fusion. The main outcome is the incidence of distal adding-on at 24 months after surgery, assessed by blinded radiographic reviewers.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, as well as preliminary efficacy of a personalized cancer vaccine alone and in combination with toripalimab in patients with resected NSCLC.

This study evaluates Patient-derived Tumor-like Cell Clusters (PTC)-guided individualized neoadjuvant therapy in patients with muscle-invasive bladder cancer who are candidates for radical cystectomy.

The goal of this clinical trial is to explore the efficacy and safety of darolutamide combined with 177Lu-PSMA-617 in treating high-risk localized prostate cancer patients who are scheduled to undergo radical prostatectomy. The main questions it aims to answer are: Does this combination treatment improve the pathological complete response rate (pCR)? What is the minimal residual disease (MRD) rate in these patients? What are the safety profiles and any adverse effects associated with this treatment? Researchers will compare the combination of darolutamide and 177Lu-PSMA-617 to a placebo to see if the combination is effective in treating high-risk localized prostate cancer. Participants will: Receive either darolutamide combined with 177Lu-PSMA-617 or a placebo every day for 12 weeks. Visit the clinic every 6 weeks for checkups and tests. Keep a diary of their symptoms and any side effects experienced during the treatment. Undergo imaging tests, including prostate MRI and PSMA PET/CT, before surgery and during follow-up.
