Clinical trials

Advanced biliary tract cancer has a poor prognosis and limited efficacy with current regimens. This multicenter single-arm phase Ib/II trial explores the efficacy and safety of HAI-GP chemotherapy combined with intraoperative arterial envafolimab and lenvatinib as first-line therapy for unresectable BTC. It conducts dose exploration to confirm the optimal dosage and evaluates clinical outcomes, aiming to establish a better comprehensive treatment strategy.

Infantile hemangioma with minimal or arrested growth (IH-MAG) is a subtype of infantile hemangioma that shows little or no obvious growth during infancy. Although these lesions may appear less active than classic infantile hemangiomas, some may still be associated with ulceration, functional risk, permanent disfigurement, or structural anomalies. This prospective observational cohort study will compare infants with IH-MAG and infants with classic infantile hemangioma at their first specialist evaluation. Each participant will undergo routine clinical assessment, standardized photography, risk classification according to the 2019 American Academy of Pediatrics guideline, and Hemangioma Severity Scale scoring. The main outcome is the initial management recommendation after specialist assessment, categorized as active management or treatment versus observation. The study will not assign any treatment. All management recommendations will be made by clinicians according to routine clinical practice and guideline-based assessment.

The goal of this clinical trial is to evaluate the safety and tolerability of an MSH2-/- tumor cell vaccine and to explore its preliminary antitumor activity and immunogenicity in adults with advanced proficient mismatch repair (pMMR) colorectal cancer who have failed, are intolerant of, or decline standard systemic therapies at West China Hospital, Sichuan University. The main objectives are to determine the incidence of dose-limiting toxicities (DLTs) and other treatment-emergent adverse events (TEAEs) related to the vaccine (n/N, %, graded per NCI CTCAE v5.0), to assess preliminary antitumor activity (objective response per RECIST v1.1, progression-free survival, and overall survival), and to characterize the vaccine's immunogenicity profile. This study using a 3+3 dose-escalation design with three dose levels of the MSH2-/- tumor cell vaccine (1×10\^7, 2.5×10\^7, and 5×10\^7 cells per dose), manufactured under GMP conditions and administered by intradermal injection. Each participant will receive four induction vaccinations (three doses every 2 weeks and a fourth dose 1 month after the third), followed by up to eight booster doses every 4 weeks based on tumor response. Participants will undergo protocol-specified safety monitoring with clinical assessments, laboratory tests, and documentation of all AEs/SAEs, and tumor response will be evaluated regularly by imaging per RECIST v1.1. After treatment completion or discontinuation, participants will enter safety and long-term follow-up for disease status and survival.

The goal of this clinical trial is to learn if the anti-fog suction device works to keep the surgical view clear during endoscopic nose-to-pituitary operations and whether it lowers the chance of brain-fluid infection. It will also learn about the safety of the device. The main questions it aims to answer are: * Does the device reduce the total time the surgeon has to stop because the lens fogs up? * What medical problems (such as nose-bleed, tube blockage, or infection) do participants have when the device is used? Researchers will compare the anti-fog device to the usual "water-squirt" method to see if the device works better. Participants will: * Have either the device or the usual water method applied during their planned pituitary surgery * Stay in the hospital for the normal recovery period (about 3-5 days) and return for a routine check-up around day 7 * Allow the study team to record operating times, any fog-related pauses, and results of blood or spinal-fluid tests taken before and after surgery

This is a Phase I, single-arm, open-label, dose-escalation study in patients with stage II or III ovarian cancer after surgery. The study will evaluate the safety, tolerability, immune response, and preliminary clinical activity of NeoOVIV, a personalized mRNA-lipid nanoparticle vaccine, when given with standard adjuvant chemotherapy and a PD-1 antibody.

Infantile hemangioma is the most common benign vascular tumor in infancy. Oral propranolol is the first-line systemic treatment for infantile hemangiomas requiring therapy. Although most patients respond well to propranolol, rebound growth may occur after treatment discontinuation, and some patients may require restarting propranolol or receiving additional treatment. In clinical practice, propranolol may be discontinued abruptly after the lesion meets discontinuation criteria, or gradually tapered over several weeks before complete discontinuation. However, high-quality randomized evidence comparing these two discontinuation strategies remains limited. This multicenter randomized noninferiority trial aims to compare the risk of rebound growth after abrupt discontinuation versus gradual tapering of propranolol in patients with infantile hemangioma who have received oral propranolol for at least 6 months and meet predefined discontinuation criteria.

Children with medulloblastoma, an aggressive brain tumor, require prolonged and complex multimodal therapy. Their primary parental caregivers bear the main responsibility for ensuring treatment adherence, yet the psychological toll on these caregivers may undermine their ability to follow prescribed regimens. This study investigates whether multidimensional parental distress predicts overall treatment adherence in this population, and which specific distress domains are most strongly associated with poor adherence. Parental distress-including depression, anxiety, and posttraumatic stress-is common among parents of children with cancer and may interfere with their ability to manage complex treatment regimens. However, no study has specifically examined whether parental distress predicts treatment adherence in children with recurrent medulloblastoma, a devastating brain tumor with a poor prognosis and no standard treatment protocol. This prospective longitudinal cohort study aims to investigate whether parental distress is a significant predictor of treatment adherence in children with recurrent medulloblastoma. A total of 450 parent-child dyads will be enrolled across 4 tertiary pediatric oncology centers. Children must have a confirmed diagnosis of recurrent medulloblastoma and be receiving active treatment. Parents (primary caregivers) will complete validated questionnaires at baseline assessing depression, anxiety, stress, and trauma-related distress using the DASS-21 and IES-R. Treatment adherence will be monitored over a 12-month follow-up period using electronic medication monitoring caps, clinic attendance records, and parent-reported medication logs. The primary outcome is the proportion of prescribed chemotherapy doses taken (treatment adherence rate). Secondary outcomes include trajectories of adherence over time and the relationship between specific dimensions of parental distress (depression, anxiety, stress, posttraumatic stress) and adherence patterns. The study will also examine whether child clinical factors (e.g., molecular subgroup, prior treatment history) and family demographic factors moderate this relationship. Findings from this study may inform the development of targeted psychosocial interventions to support distressed parents and improve treatment adherence-and ultimately clinical outcomes-in this vulnerable pediatric population. Participants can expect to be enrolled in the study for approximately 12 months.

This is a multicenter, randomized, open-label phase 2 study for men with metastatic hormone-sensitive prostate cancer. About 254 participants will first receive 6 months of darolutamide plus androgen deprivation therapy. Participants whose cancer has not progressed and who still have active tumor lesions on prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) will then be randomly assigned to one of two groups. One group will continue darolutamide plus androgen deprivation therapy. The other group will receive stereotactic body radiotherapy (SBRT) to all active tumor lesions identified by PSMA PET/CT, while continuing darolutamide plus androgen deprivation therapy. The main purpose of this study is to find out whether adding PSMA PET/CT-guided SBRT can help participants live longer without tumor growth seen on scans or death. The study will also evaluate prostate-specific antigen (PSA) changes, time to castration-resistant prostate cancer, overall survival, side effects, and quality of life.

In China, low breast-conserving surgery rates and historically minimal immediate reconstruction following mastectomy have resulted in a significant population of women living without a breast, often leading to long-term psychosocial distress. Current delayed reconstruction options are limited: traditional two-stage implant reconstruction necessitates two surgeries with associated costs and risks like infection and implant exposure, while autologous tissue transfer (e.g., TRAM/DIEP flaps), though offering superior natural aesthetics and patient satisfaction, involves extensive donor-site morbidity, prolonged recovery, and significant scarring, restricting its suitability. To address the drawbacks of both established methods-significant trauma, cost, and complexity-this study evaluates a novel technique for breast cancer patients post-mastectomy: endoscopic delayed direct-to-implant breast reconstruction. This study proposes to conduct a prospective cohort study to analyze complication rates, breast aesthetic scores, quality of life metrics, and other dimensions between delayed direct-to-implant breast reconstruction and abdominal flap breast reconstruction（DIEP and TRAM). The aim is to comprehensively evaluate the safety and clinical feasibility of endoscopic delayed direct-to-implant breast reconstruction.

Advanced solid tumors remain a major therapeutic challenge due to their complex heterogeneity and the immunosuppressive tumor microenvironment (TME). Although cancer vaccines are designed to induce long-lasting antitumor immunity, their efficacy is often limited by the TME's immune-evasive mechanisms. Building on this rationale, investigators developed a novel vaccine comprising irradiated tumor cells and stromal cells isolated from adjacent non-cancerous tissues or tumor tissues in combination with adjuvant. Irradiated tumor cells in vaccines such as YMN102, YMN103, YMN104, YMN105, YMN106, and YMN107 are transfected with GM-CSF; the others, such as YMN101 and YMN108, are not transfected with GM-CSF. Preclinical studies across multiple tumor models have demonstrated potent antitumor activity with no significant toxicity observed following administration. This first-in-human Phase I study is designed to evaluate the safety and tolerability of this irradiated vaccine in patients with advanced solid tumors, alongside a preliminary assessment of its antitumor activity and immunogenic profile. This is a first-in-human, Phase I, open-label study designed to evaluate the safety and tolerability of this novel vaccine. The study includes multiple arms targeting specific malignancies, including osteosarcoma, pancreatic cancer, HNSCC, colorectal cancer, HCC, glioma, and TNBC. The primary objective is to determine the incidence of dose-limiting toxicities (DLTs). Secondary objectives include assessing the objective response, progression-free survival (PFS), and overall survival (OS) per RECIST v1.1. Exploratory analyses will monitor dynamic changes in circulating biomarkers and intratumoral immune modulation to identify potential predictive markers of clinical response.

The CAPRA-EVO trial is a single-center, randomized, open-label study with blinded endpoint assessment comparing early evolocumab plus standard lipid-lowering therapy versus standard-of-care lipid-lowering therapy in patients with acute coronary syndrome after successful percutaneous coronary intervention. The study will use serial photon-counting coronary computed tomography angiography at baseline and 52 weeks to assess changes in non-culprit coronary plaque burden and stenosis severity. Secondary outcomes include changes in high-risk plaque features, lipid and inflammatory biomarkers, cardiovascular events, and safety outcomes. The trial aims to determine whether early intensive LDL-C lowering with evolocumab can reduce coronary plaque progression and support PCCT-CCTA as a noninvasive tool for monitoring atherosclerotic plaque dynamics.

Advanced biliary tract cancer has a poor prognosis and limited efficacy with current regimens. This multicenter single-arm phase Ib/II trial explores the efficacy and safety of HAI-GP chemotherapy combined with intraoperative arterial envafolimab and lenvatinib as first-line therapy for unresectable BTC. It conducts dose exploration to confirm the optimal dosage and evaluates clinical outcomes, aiming to establish a better comprehensive treatment strategy.

This study is a multicenter, open-label, Phase I single-arm clinical trial evaluating the safety and tolerability of a topical AKK probiotic preparation (Akkermansia muciniphila) for the prevention and treatment of radiation-induced skin injury in patients receiving radiotherapy for breast cancer, head and neck cancer (including nasopharyngeal carcinoma). A total of 40 participants are planned to receive the AKK preparation applied to the radiation field three times daily, starting one day before the first radiotherapy fraction and continuing until 14 days after the last fraction. The primary outcome is the incidence of grade ≥2 acute radiation dermatitis (ARD) assessed by RTOG and CTCAE criteria. Secondary outcomes include changes in skin micro-features under digital dermoscopy, skin microbiota composition, quality of life (Skindex-16), and safety.

This single-center, Phase 1 study is evaluating the safety, tolerability, and preliminary antitumor activity of recombinant human endostatin adenovirus injection (EDS01) given by intratumoral injection in combination with toripalimab in adults with recurrent or metastatic head and neck tumors, including nasopharyngeal carcinoma, whose disease has progressed after platinum-based systemic therapy or who are not suitable for further platinum treatment. A total of 9 participants will be enrolled in 3 planned dose groups of EDS01. EDS01 will be injected directly into an accessible tumor lesion on Days 0 and 7, and toripalimab 240 mg will be administered intravenously on Day 1 of each treatment cycle for up to 4 cycles, unless disease progression or unacceptable toxicity occurs. The study will evaluate treatment-related adverse events as well as preliminary efficacy outcomes, including tumor response, disease control, and time to progression, using clinical assessments, laboratory tests, imaging, and follow-up after treatment.

The objective of this study is to determine the maximal diameter threshold at which infants with lumbosacral, sacrococcygeal, perineal, gluteal, or lower-limb extending infantile hemangiomas should undergo screening for LUMBAR syndrome.

This is a multicenter, randomized controlled clinical trial (HOPE-07) designed to evaluate the efficacy and safety of perioperative treatment with disitamab vedotin (RC48) combined with toripalimab compared with toripalimab combined with chemotherapy in patients with resectable HER2-expressing (HER2 1+, 2+, or 3+) muscle-invasive bladder cancer (MIBC, cT2-4aN0/1M0).A total of 240 patients will be enrolled and randomized in a 1:1 ratio to receive either RC48 plus toripalimab or chemotherapy plus toripalimab, with 120 patients in each arm. The primary objective is to compare 2-year event-free survival (2-year EFS) between the two treatment groups. Secondary endpoints include pathological complete response (pCR), event-free survival (EFS), disease-free survival (DFS), 1-year event-free survival (1-year EFS), metastasis-free survival (MFS), overall survival (OS), R0 resection rate, and safety outcomes including adverse events (AEs), serious adverse events (SAEs), vital signs, physical examination, ECOG performance status, laboratory tests, and electrocardiography, assessed according to CTCAE v5.0. Exploratory objectives include assessment of quality of life using EQ-5D-5L and EORTC QLQ-C30, evaluation of associations between biomarkers (HER2 expression, PD-L1 expression, circulating tumor DNA) and treatment efficacy, and multi-omics analyses using tumor tissue, ctDNA, and urinary tumor DNA to identify potential predictive biomarkers.

This is a single-center, prospective, single-arm, open-label phase I exploratory study that plans to enroll 24 participants with solid malignancies. All participants will receive controlled cold exposure in addition to standard PD-1/PD-L1 inhibitor monotherapy or PD-1/PD-L1 inhibitor-based standard combination therapy. A 2-day cold acclimation phase will precede formal intervention, consisting of approximately 20°C exposure for 8 hours on Day -2 and approximately 18°C exposure for 10 hours on Day -1. The first combination cycle begins on Day 1 concurrently with PD-1/PD-L1-based treatment, with exposure to an 18°C temperature-controlled hospital room for 12 hours per day for 7 consecutive days. If tolerated, cold exposure may be repeated in subsequent PD-1/PD-L1 treatment cycles. The primary objective is to evaluate safety, tolerability, and feasibility. Secondary objectives are to explore preliminary antitumor activity and the effects on brown adipose tissue activation, peripheral immune profiling, circulating cytokines, metabolomics, gut microbiota, patient-reported outcomes, and tumor immune/metabolic biomarkers when paired tumor tissue is available.

This study was a prospective, single-center, open-label, single-arm, multi-dose ascending phase Ⅰ clinical trial. The investigators constructed a TM10-LNP mRNA preparation encoding CTLA-4 antibody and TGF-β trap bifunction protein (YMN-A02 bifunction RNA preparation). The aim of this study is to provide a new strategy for overcoming the immune tolerance of liver tumors and improving the response rate of immunotherapy. The investigators planned to enroll patients with advanced pMMR liver metastasis from colorectal cancer who failed standard treatment. A modified "3+3" design was used, and 10 patients were expected to be enrolled. There were four dose groups of 100μg, 250μg, 500μg and 1000μg. The trial used a modified "3+3" dose climbing design, in which one subject was set as a sentinel patient in the initial 100μg dose group. If the subject did not experience DLT during the DLT observation period, the dose was judged safe and escalation to the next group occurred. If DLT occurred, 3 additional subjects in this group would be required for further evaluation. In the subsequent 250μg, 500μg, and 1000μg dose groups, three subjects were enrolled first in each group: if there was no DLT, the number of subjects was increased. If ≥2 of the 3 cases had DLT, the escalation was terminated. If DLT occurred in 1 out of 3 subjects, 3 additional observations would be made in the same dose group. If the incidence of DLT in the total 6 subjects did not exceed 1/6 after the supplement, the escalation could be escalated. Otherwise, the escalation was terminated and the dose was considered as intolerable.

This study aims to evaluate the safety and preliminary efficacy of NALIRIFOX combined with adebrelimab and PULSAR as first-line treatment for locally advanced unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC). Additionally, it will explore potential predictive and efficacy-related biomarkers.

This is a national multicenter, prospective, cohort study. The study aims to compare surgical safety (e.g., surgical complication rates), surgery-related indicators (e.g., operation time, number of operations, surgery-related costs, contralateral breast adjustment operation rates), aesthetic outcomes (e.g., BREAST-Q scores, Harris scores, SCAR-Q scores, Ueda scores and QLQ-BR45 scores), and divorce rate between patients undergoing delayed endoscopic direct-to-implant breast reconstruction via an axillary approach and those undergoing the two-stage expander-to-implant breast reconstruction following simple mastectomy.

The goal of this clinical trial is to evaluate the anti-tumor activity, safety and tolerability of the combination of Sacituzumab govitecan and Tagitanlimab as neoadjuvant therapy in patients with resectable head and neck squamous cell carcinoma (HNSCC). It will also explore potential biomarkers related to the efficacy of this combined therapy. The main questions it aims to answer are: Does the combination of Sacituzumab govitecan and Tagitanlimab improve the major pathological response rate (MPR) in patients with resectable HNSCC? What adverse reactions (side effects) do participants experience when receiving this combined neoadjuvant therapy? Does this combined therapy improve participants' objective response rate (ORR), survival time and quality of life? This is a single-arm, open-label, prospective Phase II clinical study conducted at West China Hospital of Sichuan University. A total of 30 eligible patients will be enrolled, and no placebo control will be used. The study will evaluate the efficacy and safety of the combined therapy by monitoring clinical indicators, pathological results and adverse events throughout the trial. Participants will: Receive Sacituzumab govitecan (5mg/kg) and Tagitanlimab (900mg) intravenously every 2 weeks, for a total of 2 treatment cycles. Patients will undergo surgical resection 3-6 weeks after completion of neoadjuvant therapy. Adjuvant therapy (concurrent chemoradiotherapy or radiotherapy alone) will be administered according to pathological risk factors, together with 15 cycles of Tagitanlimab as adjuvant immunotherapy. Visit the clinic regularly for physical examinations, laboratory tests (such as blood routine, liver and kidney function), imaging examinations (such as head and neck MRI/CT) and safety checkups according to the study schedule. Provide biological samples (peripheral blood, tumor tissue, saliva, feces) at specified time points for biomarker detection. Complete quality-of-life questionnaires (such as EORTC QLQ-C30) regularly to assess changes in daily functioning. Note: Participants will not be charged for the study drugs (Sacituzumab govitecan and Tagitanlimab ), and will receive appropriate subsidies for study-related visits and blood collection. The research team will provide active treatment and corresponding compensation if participants experience study-related adverse reactions.

Variceal bleeding is a major complication of portal hypertension in patients with cirrhosis and is associated with substantial risks of rebleeding and death. Current guidelines recommend endoscopic variceal ligation combined with nonselective beta-blockers as standard secondary prophylaxis for esophageal variceal bleeding and type 1 gastroesophageal variceal bleeding. Transjugular intrahepatic portosystemic shunt can markedly reduce portal pressure and prevent recurrent variceal bleeding, but its broader use in secondary prophylaxis is limited by the risk of post-TIPS hepatic encephalopathy and liver function deterioration. The VIATORR Controlled Expansion stent is designed to allow controlled expansion between 8 and 10 mm. However, even 8-mm TIPS may still be associated with a substantial risk of overt hepatic encephalopathy. This trial evaluates an underdilated VCX-TIPS strategy, in which a commercially available 8-10 mm VIATORR Controlled Expansion stent is initially dilated only with a 6-mm balloon, aiming to achieve sufficient portal decompression while reducing the risk of excessive shunting. This is a prospective, multicenter, open-label, parallel-group, randomized superiority trial. Eligible patients with cirrhosis who have recovered from acute esophageal variceal bleeding or type 1 gastroesophageal variceal bleeding and have entered the secondary prophylaxis phase will be randomly assigned in a 1:1 ratio to receive either underdilated VCX-TIPS or endoscopic variceal ligation plus nonselective beta-blockers. The primary outcome is the composite of all-cause death or clinically significant upper gastrointestinal rebleeding within 1 year after randomization.

This is an open-label, single-arm, non-randomized, single-center, prospective phase 1 clinical trial. The study will evaluate the safety, tolerability, and preliminary antitumor activity of IMP3-saRNA (YMN-136) vaccine in patients with advanced non-small cell lung cancer. IMP3-saRNA (YMN-136) is a vaccine product prepared from IMP3 self-amplifying RNA and lipid nanoparticles. The study will enroll patients with histologically or cytologically confirmed non-small cell lung cancer who have failed standard treatment, are intolerant to standard treatment, or have refused standard treatment, and whose tumor tissue is positive for IMP3 expression. A total of 9 participants are planned to be enrolled. Participants will enter one of three dose groups sequentially: 50 micrograms, 100 micrograms, or 200 micrograms. Each dose group will include 3 participants. The study will use a 3+3 dose-escalation design. The vaccine will be administered by intramuscular injection. The immunization schedule includes 4 doses, with each dose given 3 weeks apart. The main purpose of the study is to assess safety and tolerability. Dose-limiting toxicity will be assessed from the first vaccination until 14 days after the third vaccination. Safety assessments will include adverse events, serious adverse events, physical examinations, vital signs, ECOG performance status, laboratory tests, 12-lead electrocardiogram, and echocardiography. The study will also preliminarily assess antitumor activity using RECIST version 1.1. Imaging assessments may include CT or MRI and whole-body bone scan. Additional exploratory evaluations may include blood and tumor tissue biomarker analyses, such as ctDNA, tumor markers, immune cell subsets, dendritic cell maturation, antigen-specific cytotoxic T cells, T-cell activation, antibody titers, PD-L1 expression, gene mutation analysis, and other immune-related tests.

This phase I, open-label, single-arm, non-randomized clinical trial uses a "3+3" dose-escalation design to evaluate the safety, tolerability, and preliminary efficacy of intradermal delivery of complement factor H (CFH) fragment (human, 860-1231aa) via ice microneedles for the prevention of radiation-induced skin fibrosis in patients with head and neck squamous cell carcinoma (excluding nasopharyngeal carcinoma) receiving postoperative adjuvant radiotherapy. The main questions are: 1. The safety profile, including dose-limiting toxicities (DLTs) within 28 days after the first dose, adverse events, and tolerability. 2.Preliminary efficacy, assessed by changes in irradiated skin thickness, palpation of fibrotic area, CTCAE grade ≤2 fibrosis rate, and quality of life. Participants receive CFH ice microneedle patches twice weekly for a total of 8 doses (starting at 0.5 mg, escalating to 1.0 mg and 2.0 mg), applied to the skin area to be irradiated.

The goal of this phase 1 clinical trial is to evaluate the safety, tolerability, and preliminary antitumor activity of a peptide-delivered IL-22BP biotherapy in patients with advanced solid tumors. The main questions it aims to answer are: Is the IL-22BP formulation safe and tolerable? Does the IL-22BP formulation show preliminary antitumor activity?
