Clinical trials

Pediatric malignant solid tumors (including neuroblastoma, Wilms tumor, hepatoblastoma, rhabdomyosarcoma, osteosarcoma, Ewing sarcoma, and germ cell tumors) account for approximately 60% of childhood malignancies. Despite multimodal therapy, children with relapsed or refractory disease have poor outcomes. Repeated lines of intensive salvage chemotherapy cause cumulative damage to the hematopoietic system, resulting in profound and prolonged myelosuppression (absolute neutrophil count \<0.5×10\^9/L or platelet count \<20×10\^9/L) that often fails to recover despite standard supportive care with short-acting recombinant human granulocyte colony-stimulating factor (rhG-CSF) and recombinant human thrombopoietin (rhTPO). This leads to chemotherapy delays that compromise treatment continuity and intensity. Umbilical cord blood (UCB) contains hematopoietic progenitor cells, NK cells, T lymphocytes, and various hematopoietic and immunomodulatory factors. UCB infusion has been shown to accelerate hematopoietic recovery after chemotherapy and may enhance anti-tumor immune function. This is a single-center, single-arm, prospective exploratory study. Approximately 10 children (aged 1-18 years) with relapsed or refractory malignant solid tumors who develop severe post-chemotherapy myelosuppression with delayed hematopoietic recovery (persistent ANC \<1.0×10\^9/L and platelets \<50×10\^9/L despite ≥7 days of rhG-CSF/rhTPO support, resulting in chemotherapy delay) will receive UCB infusion in addition to continuing background anti-tumor therapy and standardized hematopoietic supportive care. Each patient may receive up to 3 UCB infusions. The follow-up period is 12 weeks from the first infusion. The study aims to: (1) evaluate the effect of UCB infusion on promoting hematopoietic recovery and on-schedule chemotherapy completion (compared with institutional historical controls); (2) evaluate immune reconstitution after UCB infusion, including dynamics of T-lymphocyte subsets, NK cells, B cells, and serum cytokines; (3) assess the safety of UCB infusion; and (4) explore differences in hematopoietic recovery and immune reconstitution across tumor types and treatment backgrounds.

This is a prospective, single-center, single-arm Phase II pilot study designed to evaluate the efficacy and safety of FMT in combination with QL1706 and Bevacizumab as first-line treatment for advanced Hepatocellular carcinoma.

This is a prospective, single-center, randomized, open-label, two-arm Phase II clinical trial design to evaluate the feasibility, safety and preliminary efficacy of combining fecal Fecal Microbiota Transplantation （FMT） Combined With SHR-1701plus Nab-paclitaxel and Gemcitabine as first-line treatment in patients for locally advanced or metastatic pancreatic ductal adenocarcinoma （PDAC）.

This single center, prospective, randomized, open-label, two-arm parallel-controlled Phase II clinical trial is designed to evaluate the efficacy and safety of fecal microbiota transplantation （FMT ）combined with Nalirifox plus Serplulimab as first-line treatment in patients with locally advanced or metastatic pancreatic ductal adenocarcinoma (PDAC)

This is a Phase II clinical trial investigating the effectiveness and safety of a four-drug combination-Chidamide, Dinutuximab Beta, Irinotecan, and Temozolomide-for children with relapsed or refractory neuroblastoma. The primary goal is to evaluate how well this regimen works to control the cancer, while the secondary goal is to closely monitor its safety and side effects in these young patients.

Iparomlimab and Tuvonralimab Injection (QL1706) is a bifunctional combination antibody targeting both programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4). This is a prospective clinical study that plans to enroll screened, eligible early-stage breast-cancer patients to receive neoadjuvant QL1706 plus chemotherapy (four cycles of TP ± four cycles of AC). After the four TP cycles, imaging and core biopsy will be performed. Patients who achieve radiologic complete response will proceed directly to surgery; those who do not will receive four additional AC cycles before surgery. A key feature is the incorporation of an response-guided neoadjuvant therapy（RGN）model to identify sensitive patients who can forgo anthracyclines, thereby reducing long-term cardiotoxicity.

Anruikefen is a peripherally highly selective kappa receptor agonist that does not easily cross the blood-brain barrier, resulting in a low incidence of central adverse reactions such as respiratory depression, sedation, and addiction. As a Class 1 new drug, it was approved for marketing in China on May 13, 2025, and is indicated for the treatment of postoperative pain following abdominal surgery. Results from two Phase Ⅲ randomized controlled trials (RCTs) of Anruikefen have demonstrated its significant analgesic efficacy, with the incidence of postoperative nausea and vomiting (PONV) being 50% significantly lower than that in the placebo group, which confirms the favorable safety profile of Anruikefen Injection. Therefore, this investigator-initiated trial (IIT) is designed to further verify the efficacy and safety of Anruikefen in patients undergoing total laparoscopic distal gastrectomy for gastric cancer.

This study aims to evaluate the efficacy and safety of hyperfractionated radiotherapy (40Gy/15 fractions) compared to conventional fractionated radiotherapy (50Gy/25 fractions) in breast cancer patients undergoing breast reconstruction through a three-phase randomized controlled non-inferiority clinical trial. The primary objective is to verify that hyperfractionated radiotherapy is non-inferior to conventional fractionated radiotherapy in terms of local area control; the secondary objectives are to compare the main complications of wounds, acute and chronic toxic reactions, breast cosmetic effects, and quality of life between the two groups, thereby providing high-level evidence-based medical evidence for optimizing postoperative radiotherapy regimens for breast cancer and promoting individualized treatment. Additionally, the molecular characteristics of blood samples will be studied to identify biomarkers related to the radiotherapy process and treatment response, providing high-level evidence for immediate medium-dose low-fractionation radiotherapy after different reconstructions.

Ziwu Liuzhu Five-Element Music Therapy is a non-pharmacological intervention grounded in the traditional Chinese medicine theory of "five tones corresponding to the five viscera and five emotions," integrated with the chronomedicine framework of Ziwu Liuzhu (midnight-noon meridian flow). It delivers specific musical modes at designated two-hour intervals to resonate with meridian qi and blood, achieving the therapeutic goals of "time-matched music for organ-specific regulation." Existing meta-analyses have confirmed that five-element music therapy significantly alleviates anxiety and depression and improves quality of life in cancer patients; however, no dedicated study has been conducted in pancreatic cancer patients undergoing chemotherapy. This is a multicenter, prospective, parallel-group, non-inferiority randomized controlled trial. A total of 320 pancreatic cancer patients with mild-to-moderate anxiety receiving NALIRIFOX or AG (nab-paclitaxel + gemcitabine) chemotherapy will be enrolled and randomly assigned in a 1:1 ratio to either the Ziwu Liuzhu Five-Element Music Therapy group or the Mindfulness-Based Stress Reduction (MBSR) group. The intervention group receives 20-minute sessions, three times daily, for 8 weeks of Ziwu Liuzhu Five-Element Music listening. The control group receives an 8-week standard MBSR program consisting of twice-daily home practice and weekly online group sessions. The primary outcome is the change in HADS-Anxiety score from baseline to week 8. Secondary outcomes include depression (HADS-D), quality of life (EORTC QLQ-C30), and biomarkers (NLR, MLR, albumin, etc.). This trial aims to demonstrate that Ziwu Liuzhu Five-Element Music Therapy is non-inferior to a standardized psychological intervention (MBSR) for improving Psychological Distress in pancreatic cancer patients during chemotherapy.

This prospective, single-center, single-arm phase II study will evaluate the efficacy, safety, and technical feasibility of an organ-preserving radiotherapy strategy for patients with localized rectal adenocarcinoma who are medically inoperable, decline radical surgery, or are considered technically unresectable without distant metastases. Participants will receive pelvic external beam radiotherapy followed by high-dose-rate (HDR) endorectal brachytherapy. Concurrent capecitabine may be given during external beam radiotherapy to participants who are considered able to tolerate chemotherapy. During HDR brachytherapy, all participants will be treated using a patient-specific 3D-printed guide template and individualized tungsten-alloy local shielding. The guide template is designed to improve applicator positioning and treatment reproducibility, while the local shielding is intended to reduce radiation exposure to non-target rectal wall. The study will enroll 50 participants. The primary objectives are to evaluate the 12-month clinical complete response rate and the technical completion rate of the HDR brachytherapy platform. Secondary assessments include organ preservation, local regrowth, survival outcomes, treatment-related toxicity, quality of life, and anorectal function.

This is a single-center, single-arm, open-label phase II exploratory study. A total of 30 patients aged 18-75 years with ECOG PS 0-1, pathologically confirmed advanced breast cancer with ultra-low HER2 expression will be enrolled. Eligible patients must have at least one measurable lesion and have received 1-2 lines of prior systemic therapy for advanced disease. All participants receive intravenous SHR-A1811 at 4.8 mg/kg every 3 weeks, until disease progression, intolerable adverse events or other discontinuation criteria. The primary endpoint is objective response rate (ORR). Secondary endpoints include progression-free survival (PFS), overall survival (OS), duration of response (DOR), disease control rate (DCR), clinical benefit rate (CBR), and safety profile.

This is a prospective, single-center, single-arm, open-label phase II exploratory study to evaluate the efficacy, safety, and immune remodeling effects of stereotactic body radiotherapy (SBRT) combined with reduced-dose anthracycline chemotherapy and the PD-1 inhibitor toripalimab as neoadjuvant therapy, followed by postoperative stratified maintenance therapy, in patients with localized high-risk undifferentiated pleomorphic sarcoma (UPS). A Simon two-stage design will be used, with 39 patients planned (stage 1: 13 patients; 35 patients in total, including a 10% dropout rate). Treatment consists of SBRT (8-10 Gy in 5 fractions) followed by toripalimab (240 mg intravenously every 3 weeks, 3 cycles in the neoadjuvant phase) combined with liposomal doxorubicin (30-40 mg/m² intravenously every 3 weeks, 2 cycles in the neoadjuvant phase). After response evaluation, radical surgery is performed. Postoperative stratified maintenance therapy is delivered according to pathological response: patients achieving major pathologic response (MPR) or hyalinized pathologic response (HPR) receive toripalimab monotherapy (240 mg every 3 weeks, up to 14 cycles), while those not achieving MPR/HPR receive toripalimab combined with liposomal doxorubicin (2-4 cycles). The primary endpoint is the rate of major pathologic response (MPR). Secondary endpoints include the rate of hyalinized pathologic response (HPR), radiologic objective response rate (ORR), R0 resection rate, limb salvage rate, and safety.

Inavolisib is an effective targeted therapy for certain patients with breast cancer, but it may cause high blood sugar (hyperglycemia) as a side effect. This multicenter, real-world study aims to evaluate whether implementing a risk-stratified management strategy for inavolisib-related hyperglycemia can positively impact patients' adherence to their treatment. By categorizing patients based on their blood sugar risk levels and applying corresponding management plans, researchers hope to improve medication compliance and overall clinical outcomes in real-world clinical practice.

This prospective, multicenter, single-arm phase II clinical trial is designed to enroll patients with spinal metastases classified as Bilsky grade 1c-3 who will receive stereotactic body radiation therapy (SBRT). The objective of this study is to assess the efficacy and safety of SBRT in the treatment of spinal metastases with epidural spinal cord compression (Bilsky grade 1c-3).

This two-stage, multicenter, randomized open-label phase II trial enrolls untreated resectable stage II-III gastric/gastroesophageal junction adenocarcinoma patients with any HER2 expression. Stage 1 is a safety lead-in cohort of 6 patients receiving Trastuzumab Rezetecan(SHR-A1811)+Retlirafusp alfa(SHR-1701) plus CAPOX to assess dose-limiting toxicity (DLT) within 21 days after initial dosing. If safety risk is acceptable, stage 2 will randomize 74 eligible patients 1:1 into two parallel cohorts stratified by HER2 status. Cohort1 receives perioperative Trastuzumab Rezetecan(SHR-A1811)+Retlirafusp alfa(SHR-1701)+CAPOX; Cohort2 receives dual targeted-immunotherapy without chemotherapy (Trastuzumab Rezetecan+Retlirafusp alfa). All patients undergo D2 radical gastrectomy after neoadjuvant therapy, followed by adjuvant treatment and Retlirafusp alfa(SHR-1701) maintenance up to maximum 17 total cycles. The primary endpoint is pCR rate evaluated by CAP pathological criteria. Secondary endpoints include R0 resection rate, EFS, DFS, OS and perioperative/surgical/systemic safety profiles. Biomarker exploratory analysis will be performed to evaluate the correlation between PD-L1, MSI, TMB and clinical efficacy.

This study observes the effectiveness of high-precision radiation therapy using the Edge system after surgery for patients with spinal metastases. Spinal metastases can press on the spinal cord and cause pain, weakness, or paralysis. This treatment uses higher doses of radiation in fewer sessions (hypofractionated stereotactic body radiotherapy) delivered precisely by the Edge machine to target remaining tumor cells while protecting the spinal cord. The study aims to see if this approach improves local tumor control, improves neurological function, shortens treatment duration, and improves quality of life in these patients. The study is observational, meaning patients receive standard care, and data is collected to evaluate the outcomes.

This study aims to evaluate the efficacy and safety of Iparomlimab and Tuvonralimab (the combination antibody) combined with SBRT and Lenvatinib in the perioperative treatment of patients with potentially resectable intermediate-stage hepatocellular carcinoma.. The objective is to explore potential survival benefits for this population and provide patients with more effective treatment options.

This is a prospective, randomized, controlled, exploratory Phase II clinical study. Approximately 60 eligible patients with hepatocellular carcinoma and portal vein tumor thrombus who have received three cycles of target-immunotherapy induction and have non-progressive disease will be enrolled. All patients must be considered unresectable or unable to tolerate surgical resection by MDT review and must provide written informed consent. Participants will be randomized 2:1. Forty patients will undergo open or percutaneous IRE followed by continuation of the original target-immunotherapy regimen; twenty patients will continue the original treatment regimen alone. OS, PFS, tumor response, QoL, safety, and postoperative outcomes will be observed.

Baduanjin is a traditional Chinese mind-body exercise originating from the Song Dynasty, integrating body adjustment, breathing regulation, and mental focus. With a metabolic equivalent of approximately 2.4 METs, it is classified as low-intensity aerobic exercise incorporating resistance, flexibility, and balance components. Accumulating evidence has demonstrated significant improvements in quality of life and psychological symptoms among various cancer populations including breast and lung cancer. However, no study has specifically investigated its effects in pancreatic cancer patients undergoing chemotherapy. This is a multicenter, prospective, parallel-group randomized controlled trial. A total of 96 pancreatic cancer patients receiving NALIRIFOX chemotherapy will be enrolled and randomly assigned in a 1:1 ratio to either a 12-week Baduanjin exercise intervention group or a usual care control group. The intervention comprises a phased, symptom-guided program integrating seated and standing Baduanjin exercises, with intensity and format dynamically adjusted according to the temporal pattern of chemotherapy-related adverse events. The primary outcome is quality of life assessed by the EORTC QLQ-C30. Secondary outcomes include anxiety and depression (HADS), cardiopulmonary function (FEV1, FVC, 6-minute walk test), treatment tolerance (number of completed chemotherapy cycles, body weight change), and biomarkers (CRP, NLR, etc). Safety events will be monitored throughout the study. This trial aims to provide evidence for a safe and feasible non-pharmacological exercise rehabilitation strategy for pancreatic cancer patients during chemotherapy.

Irreversible electroporation is a non-thermal ablative technology that uses high-voltage electric pulses to create permanent nanopores in tumor cell membranes, leading to apoptosis or other forms of cell death. Because the mechanism is primarily non-thermal, IRE may better preserve extracellular matrix, bile ducts, vessels, and other critical structures than thermal ablation, which is relevant for tumors adjacent to major vascular or biliary anatomy. The main anticipated clinical value of IRE in these protocols is local disease control and potential survival benefit when used after induction therapy in patients with non-progressive disease. The procedure may be performed by open or percutaneous access according to tumor location, safety considerations, and institutional expertise. Perioperative management, imaging guidance, and post-procedure monitoring will follow institutional standards. Post-IRE gastrointestinal dysfunction may occur. Symptom-directed supportive care, including electroacupuncture where appropriate and approved by the investigator, may be used as supportive management. Such care is not intended to replace oncologic treatment and will be recorded as concomitant treatment when administered.
