Clinical trials

The purpose of this study is to learn how well a combination of iparomlimab and tuvonralimab (QL1706), lenvatinib, radiotherapy, and hepatic arterial infusion chemotherapy (HAIC) works and how safe it is for people with hepatocellular carcinoma (HCC) that has grown into the portal vein, forming a portal vein tumor thrombus (PVTT). Participants will receive iparomlimab and tuvonralimab together with lenvatinib, radiotherapy directed at the portal vein tumor thrombus, and HAIC, which delivers chemotherapy directly through the hepatic artery. Researchers will evaluate how long the cancer remains controlled without getting worse, how much the tumors shrink, how long participants survive, and whether the treatment makes surgery possible for some participants. Treatment-related side effects will also be assessed. The study will also explore whether features in tumor tissue and blood are associated with treatment response and may help identify patients who are more likely to benefit from this treatment strategy.

The goal of this prospective observational study is to evaluate how well a previously developed prediction model can estimate outcomes in adults with gastric cancer. The model combines information from computed tomography (CT) images obtained before treatment with routine clinical information. The main questions are how well the model predicts how long participants live after treatment begins and whether their cancer progresses. Participants will receive their usual medical care. Researchers will collect pretreatment CT images, basic clinical and tumor information, laboratory and tumor marker results, treatment information, and follow-up outcomes obtained during routine care. These data will be entered into the predefined prediction model, and the model's predictions will be compared with what actually happens during follow-up. The study will not change the participants' usual treatment. Model predictions will be used for research purposes only and will not be used to make treatment decisions.

The objectives are to evaluate the safety and tolerability in patients following intravenous administration of YOLT-204 and to preliminarily assess its effect on fetal hemoglobin levels in plasma. In this study, the maximum screening period of the main study is 60 days, the treatment day is Day 0 (D0), and the safety follow-up period is up to Week 52 after administration.

Neoadjuvant therapy has been widely applied to locally advanced rectal cancer. However, about 50% of patients receiving this therapy do not respond well as evidenced by the fact that their T or N stages are not effectively decreased judged by postoperative pathological examination. The purpose of this trail is to identify the biomarkers (from within patients' tumor mass before neoadjuvant therapy) to predict resistance to neoadjuvant therapy. These biomarkers can help stratify neoadjuvant-resistant patients towards surgery while avoiding unnecessary chemoradio-based neoadjuvant therapy.

The goal of this clinical trial is to learn if sorbitol works to enhance the therapeutic effect of neoadjuvant chemotherapy combined with Tirellizumab (PD-1 inhibitor) in patients with locally advanced gastric cancer. It will also learn about the safety of sorbitol. The main questions it aims to answer are: Does sorbitol enhance the therapeutic effect of immunotherapy and increase the major response rate in patients with locally advanced gastric cancer? Does sorbitol with neoadjuvant chemotherapy combined with Tirellizumab (PD-1 inhibitor) can improve the prognosis of patients with locally advanced gastric cancer? Researchers will compare sorbitol to a standard-of-care treatment (aPD-1 + SOX chemotherapy) to see if sorbitol works to enhance the therapeutic effect (Add-on Effect) of neoadjuvant chemotherapy combined with Tirellizumab (PD-1 inhibitor) in patients with locally advanced gastric cancer. Participants will: Take sorbitol every day for 3 months in 3 treatment cycles Visit the clinic once every 4 weeks for checkups and tests Keep a diary of their symptoms and the number of times they use a rescue inhaler Participants will follow up as planned until PD occurs, informed consent is withdrawn, or follow-up is lost (whichever occurs first). After the end of treatment and safety follow-up, all subjects will be followed up for survival (OS data collected every 3 months ±14 days).

Sepsis is defined as a life-threatening organ dysfunction that is caused by a dysregulated host response to infection. Severe sepsis is the most common cause of death among critically ill patients in non-coronary intensive care units (ICU). Sustained excessive inflammation and immune dysfunction have been confirmed to play a key role in organ damage and early death of sepsis patients. Therefore, it is important to reduce excessive inflammatory response mediated by immune cells and pro-inflammatory cytokines in the acute phase of sepsis. Single-cell RNA sequencing performed on both septic patients and mice suggest that changes in Tcm (CD3+ CD8+ CD44+ CD127+ CD62L+) and Tem (CD3+ CD8+ CD44+ CD127+ CD62L -) in the acute phase of sepsis may play an important role in sepsis. In addition, animal researches showed that Tcm and Tem decreased decreased continuously at 24, 48 and 72h after cecal ligation and perforation (CLP) in mice, and the adoptive transfer of Tcm , sorting from spleen of mice 24h after CLP , but not Tem improved 7-day survival rate of sepsis mice. This observational study is aimed to investigate the quantity and proliferation of Tcm and Tem in the acute phase of sepsis and their correlation with severity level and mortality of septic patients in ICU.

Multidrug-resistant organism (MDRO)-infection represents a substantial global health burden. In the intensive care unit (ICU), the concurrent administration of antibiotics, opioids, proton pump inhibitors (PPIs), vasoconstrictors, and parenteral nutrition-compounded by the intrinsic severity of critical illness-induces profound gut microbiota dysbiosis. Accumulating preclinical and clinical evidence indicates that such intestinal dysregulation may trigger distal immunomodulatory and microbial shifts in the lung via the gut-lung axis, thereby contributing to pulmonary microecological imbalance and impairing recovery trajectories. Although pulmonary microecology has garnered increasing scientific attention, the causal and temporal relationship between gut dysbiosis and the establishment or exacerbation of pulmonary microbial dysbiosis in MDRO-infecction remains inadequately characterized. As a result, it is currently unclear whether gut dysbiosis serves as a primary pathogenic driver, a disease-amplifying factor, or a secondary epiphenomenon in the context of MDRO-infecction-associated lung injury. Fecal microbiota transplantation (FMT) is a targeted microbiome-modulating intervention that involves the transfer of functionally diverse, minimally processed microbial communities from comprehensively screened healthy donors to restore ecological stability and functional redundancy in the recipient gut. Robust clinical data demonstrate that FMT effectively decolonizes the gastrointestinal tract of MDROs and reduces the incidence of secondary infections in immunocompetent, non-critically ill populations. Over the past decade, FMT has demonstrated reproducible efficacy in recurrent Clostridioides difficile infection and emerging promise in select extra-intestinal inflammatory conditions-highlighting its capacity as a mechanism-informed strategy for systemic host-microbe recalibration. Given the established role of the gut as a reservoir for enteric pathogens implicated in sepsis, hospital-acquired bloodstream infections, and ventilator-associated pneumonia (VAP), we propose a prospective, single-center, open-Label, randomized controlled trial (RCT) enrolling mechanically ventilated adults with MDRO-infeccted ventilated patients. The primary objective is to evaluate whether adjunctive FMT-delivered via nasojejunal tube-decrease 28-day mortality.

The goal of this clinical study is to learn if IN026 Injection is safe and works to lower uric acid levels in adults with refractory gout (gout that does not respond well to standard treatments). The main questions it aims to answer are: * What medical problems do participants have when taking IN026, such as changes in vital signs, blood tests, or heart rhythm? * How does the body absorb, process, and respond to IN026, and does it trigger an immune reaction? * Does IN026 lower uric acid levels in the blood and reduce tophi? Investigator will start with lower doses of IN026 and slowly increase the dose to find the well-tolerated dose. Participants will: * Receive IN026 through an intravenous (IV) drip into a vein at a set dose. * Complete a screening period of up to 4 weeks, followed by treatment and check-ups for up to 20 weeks. * Have blood and urine samples taken at set times to check safety and how the body responds to IN026.

Acute graft-versus-host disease remains a major complication after haploidentical hematopoietic stem cell transplantation. Methotrexate is commonly used as part of graft-versus-host disease prophylaxis, but it may be associated with delayed hematopoietic recovery and transplant-related toxicities, including oral mucositis. This is a prospective, multicenter, randomized, open-label, parallel-controlled Phase III clinical trial designed to evaluate an anti-CD25 monoclonal antibody regimen compared with methotrexate for the prevention of acute graft-versus-host disease after haploidentical hematopoietic stem cell transplantation. Eligible patients with hematologic malignancies scheduled to undergo haploidentical allogeneic hematopoietic stem cell transplantation will be randomly assigned in a 1:1 ratio to receive either methotrexate-based prophylaxis or anti-CD25 monoclonal antibody-based prophylaxis, in combination with standard graft-versus-host disease prophylaxis including anti-thymocyte globulin, calcineurin inhibitor, and mycophenolate mofetil. The primary objective is to compare 12-month graft-versus-host disease-free, relapse-free survival between the two groups. Secondary objectives include comparison of acute graft-versus-host disease, chronic graft-versus-host disease, oral mucositis, hematopoietic recovery, cytomegalovirus and Epstein-Barr virus reactivation, infection, relapse, non-relapse mortality, overall survival, and leukemia-free survival.

This prospective observational cohort study investigates the subset-specific metabolic adaptation and functional remodeling of cytotoxic γδT cells in critically ill patients with and without sepsis. Emerging evidence indicates that γδT cells, as a bridge between innate and adaptive immunity, play a critical role in early anti-infection defense during sepsis. However, the functional status and underlying regulatory mechanisms of cytotoxic γδT cells in septic patients remain incompletely understood. Our preliminary single-cell transcriptomic analysis revealed that cytotoxic γδT cells from septic patients exhibit significant alterations in cytotoxicity-associated molecules (GZMB, PRF1, GNLY) and mitochondrial oxidative phosphorylation (OXPHOS) pathway genes, particularly COX6C, which correlates with cytotoxic effector molecule expression. This study aims to systematically characterize the proportion, cytotoxicity, and mitochondrial metabolic function of circulating cytotoxic γδT cells across three cohorts: healthy controls, critically ill non-septic patients, and critically ill septic patients. By integrating flow cytometry, mitochondrial function assays, and functional validation experiments, we seek to elucidate the role of COX6C-mediated mitochondrial metabolic abnormalities in cytotoxic γδT cell dysfunction, providing theoretical basis for understanding immune dysregulation in sepsis and identifying novel therapeutic targets.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, representing one of the leading causes of death in intensive care units (ICUs) worldwide. Gut microbiota disruption is increasingly recognized as a key driver of persistent inflammation and multiple organ dysfunction in septic patients. Fecal microbiota transplantation (FMT) has emerged as a promising approach to restore gut microbial homeostasis. This study hypothesizes that FMT acts not through long-term engraftment of donor microbes, but via a "functional pulse" - a potent, transient biological intervention that delivers high-dose microbial metabolites (e.g., short-chain fatty acids), competitively inhibits pathogens, and rapidly modulates intestinal immune cell functions. This is a single-center, open-label, randomized controlled trial conducted in the ICU of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. A total of 60 adult patients diagnosed with sepsis according to Sepsis-3 criteria within 24 hours of ICU admission will be randomized in a 1:1 ratio to receive either ICU standard care alone (control group) or ICU standard care plus FMT administered via a nasojejunal tube for three consecutive days (intervention group). The primary endpoint is all-cause mortality at 90 days. Secondary endpoints include ICU mortality, in-hospital mortality, 28-day mortality, changes in gut microbiota composition and metabolites, serum citrulline levels as a marker of intestinal barrier function, Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, vasopressor requirements, C-reactive protein and procalcitonin levels, fluid balance, incidence of ICU delirium and feeding intolerance, and 90-day hospital readmission rate. Safety outcomes include gastrointestinal symptoms and transient fever.
