Clinical trials

This prospective, two-stage clinical trial aims to evaluate the safety, preliminary efficacy, and reproductive outcomes of oral Fecal Microbiota Transplantation (FMT) freeze-dried capsules in overweight and obese patients with Polyendocrine Metabolic Ovarian Syndrome (PMOS) undergoing Frozen-Thawed Embryo Transfer (FET).The study is implemented in two sequential phases: Phase Ⅰ (Pilot Exploration): A prospective, open-label, single-arm exploratory study in an initial evaluable cohort (n=11) to evaluate preliminary safety, dynamic gut microbiota colonization, endocrine/metabolic parameters, and pregnancy outcomes following FET. Phase Ⅱ (Confirmatory RCT): A planned multicenter, prospective, randomized controlled trial (RCT) designed to validate the clinical efficacy and underlying mechanisms of oral FMT capsules compared with control interventions, based on findings established in Phase Ⅰ.

This study is a two-arm, multicenter, randomized controlled clinical trial on whether single-port extraperitoneal VIP RARP is non-inferior to multi-port transperitoneal RARP in terms of functional recovery rate and other key metrics.

The goal of this observational study is to prospectively validate the efficacy of an AI multimodal model constructed based on multi - sequence orbital MRI in the diagnosis, activity and severity assessment, and prognosis prediction of thyroid - associated ophthalmopathy (TAO) in real - world clinical scenarios. The main questions it aims to answer are: Can AI models accurately assess the presence, activity, and severity of Thyroid-Associated Orbitopathy (TAO)? Can AI models predict the prognosis of TAO? Researchers will compare the diagnostic accuracy of the AI model for TAO patients and healthy subjects to evaluate its diagnostic performance. Participants will undergo a standardized, study - specific multimodal orbital MRI scan (sequences include T1WI, T2WI, STIR, and research sequences such as Magic, IDEAL - IQ, DWI, ASL, CEST). And will systematically acquire ocular ultrasound images from TED patients (active and inactive stages), non-TED ophthalmic disease controls, and healthy volunteers. AI-driven deep learning techniques (convolutional neural networks) will be applied to achieve automatic segmentation of key structures (extraocular muscles, optic nerve, lacrimal gland, and retrobulbar soft tissue). High-throughput radiomic features encompassing morphological parameters and gray-level texture patterns will be extracted. Machine learning algorithms will then be employed to construct objective prediction models for TED screening and activity staging, with MRI findings and CAS scores serving as the reference standards for external validation.

Patients with locally advanced gastric cancer (LAGC), particularly those with serosal invasion, remain at high risk of peritoneal recurrence despite standard perioperative treatment. Hyperthermic intraperitoneal chemotherapy (HIPEC) may eradicate free intraperitoneal tumor cells and microscopic peritoneal disease while potentially enhancing systemic anti-tumor immune activation. This is a prospective, single-center, single-arm exploratory study evaluating a HIPEC priming strategy followed by serplulimab-based neoadjuvant therapy in patients with locally advanced gastric cancer (cT3-4aN+M0). Eligible patients will undergo diagnostic laparoscopy confirming no visible peritoneal metastasis (P0) and negative peritoneal cytology (CY0), followed by docetaxel-based HIPEC. After recovery from HIPEC, patients will initially receive one cycle of serplulimab combined with fluoropyrimidine monotherapy (S-1 or capecitabine), followed by subsequent cycles of serplulimab combined with SOX/XELOX chemotherapy prior to radical gastrectomy. The primary endpoints are pathological complete response (pCR) rate and major pathological response (MPR) rate. Secondary endpoints include R0 resection rate, objective response rate (ORR), peritoneal recurrence-free survival (PRFS), overall survival (OS), and safety.

The aim of this clinical study is to explore the impact of whether radiotherapy is administered after spinal metastasis surgery on the prognosis and survival of patients, to describe the clinical outcomes, and to optimize future clinical decisions.

Metastatic spinal tumors represent a common and devastating complication in patients with advanced solid malignancies. Up to 40% of cancer patients may develop spinal metastases during the course of their disease, often resulting in intractable pain, neurological deficits, and spinal instability. One of the most serious consequences is motor paralysis caused by metastatic epidural spinal cord compression (MESCC), which can severely impair patients' quality of life and limit their ability to receive subsequent anti-tumor therapy. Although surgical decompression and stabilization are recognized as effective strategies for relieving spinal cord compression and restoring spinal integrity, the neurological prognosis for patients who present with paralysis remains uncertain and heterogeneous. This prospective, single-center, observational cohort study aims to evaluate the early and mid-term neurological recovery trajectories in patients with paralysis caused by spinal metastases, and to identify perioperative clinical factors associated with favorable or poor functional outcomes. The study will be conducted at Shanghai Changzheng Hospital, a tertiary care academic center with extensive experience in spinal oncology and multidisciplinary cancer care. The investigators plan to consecutively enroll adult patients (aged 18-80) diagnosed with spinal metastatic tumors who present with motor paralysis and are deemed appropriate surgical candidates by a multidisciplinary tumor board. Participants will undergo surgical decompression and stabilization based on individualized tumor location and spinal instability. The study does not involve any investigational drug or device. All surgical procedures and adjuvant treatments (such as radiotherapy or systemic therapy) will be delivered according to standard of care. Preoperative evaluations will include spinal imaging (MRI, CT), neurological scoring using the ASIA Impairment Scale, and assessments of systemic condition, spinal instability (SINS), and epidural compression severity (ESCC scale). Participants will be followed at 2 weeks, 1 month, 3 months, 6 months, and 12 months after surgery to monitor neurological recovery, pain control, bowel/bladder function, treatment complications, and survival. The primary outcome is the improvement in motor function at 1 month postoperatively, quantified by changes in ASIA motor scores. Secondary outcomes include longer-term neurological recovery, progression of bowel and bladder function, quality of life, complication rates, disease progression, and survival outcomes. Additional analyses will explore the impact of variables such as timing of surgery, tumor histology, location of compression, and performance status on recovery. This study will employ both univariate and multivariate statistical methods to identify independent predictors of postoperative neurological improvement, using logistic regression and time-to-event analyses. A total of 150 participants will be recruited, based on power analysis accounting for key covariates and anticipated dropout rates. Through this prospective clinical registry and analysis, the study aims to provide evidence-based data to guide clinical decision-making in the management of MESCC with paralysis. The findings will help inform surgical indications, optimize timing of intervention, and support the development of prognostic tools for patient counseling. Given the limited life expectancy of many patients with advanced cancer, maximizing early neurological recovery may directly impact patient autonomy, eligibility for systemic therapy, and overall quality of life.

This trial is a single-center, single-arm exploratory clinical study aimed at assessing the safety, tolerability, and preliminary efficacy of a single intra-articular injection of hiSCs for the treatment of rheumatoid arthritis.

This study aims to see if the amount of iron in tears is linked to how severe dry eye disease is. We hope this can lead to a new way to help diagnose and understand dry eye. This is an observational study. We will compare tear samples from people with dry eye to samples from people with healthy eyes. We will measure the iron content in the tears and see if it correlates with standard dry eye test results and symptom scores.

Colorectal cancer (CRC) is the third most common malignant tumor worldwide and the second leading cause of cancer-related deaths. Despite recent progress in CRC research, approximately 15% to 30% of patients have metastatic lesions at the time of initial diagnosis, and another 20% to 50% of patients with primary localized CRC eventually develop metastatic disease. The conventional treatment for first-line metastatic colorectal cancer (mCRC) is chemotherapy based on fluorouracil combined with anti-EGFR/VEGF targeted drugs. However, some mCRC patients may not be able to receive standard dual or triple chemotherapy combined with targeted therapy due to factors such as advanced age, poor physical condition, comorbidities, or personal preferences. Therefore, exploring new, highly effective, and low-toxicity treatment regimens is of significant clinical importance. The combination of immune checkpoint inhibitors and antiangiogenic TKIs is expected to form a strong synergistic antitumor effect, which opens up a new approach for "chemotherapy-free" treatment of mCRC when the immune system is functioning normally. Previously, we conducted the APICAL-CRC study, enrolling a total of 30 patients. The clinical objective response rate (ORR) was 48.3%, the disease control rate was 89.7%, and the median progression-free survival (mPFS) and median overall survival (mOS) were 8.6 months and 22.9 months, respectively. Subgroup analysis later revealed that the ORR for non-liver metastasis patients was 70%, with an mPFS of 14.9 months, significantly higher than that of liver metastasis patients (ORR 36.8%). At the same time, patients with better physical performance scores (ECOG PS 0-1) had an ORR of 66.7%, which was superior to that of patients with ECOG PS 2 (21.4%). In terms of safety, the incidence of grade ≥ 3 treatment-related adverse events (TRAEs) for the combination of anlotinib and sintilimab was only 13.3%. Based on the preliminary results of the APICAL-CRC study, we consider further precise screening of the advantageous population among advanced CRC patients for subsequent research. We plan to limit the enrolled patients to those without liver metastasis and with ECOG PS 0-1, providing new strategies and methods for precise treatment of advanced CRC.The purpose of this study is to evaluate the efficacy and safety of anlotinib combined with sintilimab as first-line treatment for non-liver metastatic advanced colorectal cancer. The study will be conducted at Shanghai Changzheng Hospital. The study drugs, anlotinib and sintilimab, are both marketed drugs in China.

This study is a single-centre, randomised, paired 24-week intervention dosing trial. Its purpose is to evaluate the safety profile and efficacy of the investigational drug in subjects with metastatic hormone-sensitive prostate cancer receiving oral LC-K76 treatment. Following a screening period not exceeding three weeks, subjects will enter a one- to two-week matching and randomization phase. Subsequently, subjects will be assigned to receive the study drug for a 24-week treatment period, followed by a 24-week follow-up period.

This study focuses on eye health and visual function in patients with Thyroid-Associated Ophthalmopathy (TAO), a condition that often causes bulging eyes and restricted eye movement. The purpose of this study is to use non-invasive eye-tracking technology to evaluate how the disease affects eye movement function. The investigators hypothesize that compared to healthy individuals, patients with TAO will show measurable differences in eye stability and the ability to track moving objects. Additionally, the investigators believe the disease may alter how patients visually scan faces (e.g., avoiding eye contact). The study will enroll 100 participants, including both patients and healthy volunteers. By recording gaze patterns while participants look at a screen, the investigators aim to objectively quantify the physical and social impact of the disease, providing better data for future treatment plans.

Concurrent therapies such as hepatoprotective agents, lipid-lowering medications, and antihypertensive treatments will remain unchanged, with close monitoring of relevant parameters. No additional prescription or over-the-counter drugs that may affect fatty liver progression or alter gut microbiota composition will be permitted during the study. The primary endpoint will be assessed at 24 weeks. If liver proton density fat fraction (PDFF) remains ≥ 8% after 24 weeks of rifaximin therapy, treatment will be extended for an additional 12 weeks, followed by reevaluation of PDFF changes. The maximum total treatment duration will not exceed 48 weeks. All patients will undergo a 24-week post-treatment follow-up period after discontinuation of rifaximin. Investigational Drug: Rifaximin (Alfa Wassermann S.p.A., Italy).

Thyroid-associated ophthalmopathy (TAO) is an organ-specific autoimmune disease closely related to thyroid disease, which leads the incidence of orbital disease in adults and is the most common cause of diffuse toxic goiter (Graves disease, GD). The clinical manifestations of TAO are complex and varied. In severe cases, it may seriously impair visual function, affect daily life, and even cause corneal ulceration, perforation, and blindness. Therefore, a reasonable and effective treatment plan should be chosen according to the degree of TAO. IBI311 is a fully human monoclonal insulin-like growth factor-1 receptor inhibitory antibody. It has binding activity against IGF-1R positive cells, can block the binding of IGF-1 and IGF-2 to IGF-1R, and has a dose-dependent effect. It can inhibit the proliferation of HT29 cells caused by the activation of the IGF-1R signaling pathway. Meanwhile, it can dose-dependently inhibit the proliferation of orbital fibroblasts and the secretion of hyaluronic acid (HA) in patients with TAO. However, there are still significant gaps in the existing research evidence: There is a lack of reports on the efficacy and safety of IBI311 in inactive moderate to severe TAO patients. The aim of this clinical study is to: 1. To evaluate the efficacy of IBI311 treatment in patients with inactive moderate to severe TAO. 2. To observe the safety of IBI311 treatment in patients with inactive moderate to severe TAO.

The goal of this observational study is to evaluate the long-term effects of sacral tumor resection on sacral nerve function in patients with primary sacral tumors, including chordomas and chondrosarcomas. The study will primarily focus on understanding how the level of sacral resection impacts postoperative motor, bowel, bladder, and sexual functions. The main questions it aims to answer are: How does the level of sacral resection influence bowel and bladder function at 12 months post-surgery? What is the role of preserving the sacral nerve root in maintaining motor function and sexual function? Participants will include patients who have undergone sacral tumor resection and will be followed for 12 months post-surgery. They will provide data on their bowel, bladder, and motor functions, as well as sexual function, through clinical evaluations and standardized questionnaires. Participants will: Complete surveys on bowel, bladder, and motor function at baseline and at 3, 6, and 12 months after surgery Undergo clinical assessments, including anorectal manometry, post-void residual urine volume measurements, and sensory evaluations Be evaluated for changes in sexual function using standardized surveys like IIEF (for males) and FSFI (for females)

This study is an exploratory clinical trial. It is intended to investigate the efficacy of mesenchymal stem cell-derived exosome nebulization in the treatment of postinfectious cough through a randomized controlled clinical study, with a view to providing better treatment options for patients with postinfectious cough, improving their quality of life, and providing reference data for the subsequent multi-center clinical trials.

Hemorrhage on the surface of cancellous bone presents a significant challenge in orthopedic surgery. Traditional bone wax, commonly utilized for hemostasis in bone wounds, is non-absorbable and associated with various complications, including pseudarthrosis, paralysis, venous sinus thrombosis, chronic inflammation, allergic reactions, and infections, thereby limiting its clinical utility. In contrast, absorbable bone wax, primarily composed of medical-grade water-soluble polymer materials, exhibits excellent biocompatibility. It is fully absorbed, excreted, or eliminated by the body without leaving toxic residues. This study employs a rigorous efficacy design to select an appropriate patient cohort for lumbar fusion surgery, based on specific inclusion and exclusion criteria. Participants are randomly assigned to either an experimental group receiving absorbable bone wax or a control group receiving traditional bone wax, facilitating a randomized, open-label, parallel-controlled clinical trial. This study aims to evaluate the comparative effects of absorbable bone wax versus traditional bone wax on the rate of bone fusion following hemostasis of bone wounds. The objective is to furnish robust evidence-based insights into the application of absorbable bone wax for bone wounds necessitating fusion, thereby establishing a safe, effective, and broadly applicable technique for bone wound hemostasis in clinical practice.
