Clinical trials

The goal of this observational study is to learn about cardiac safety monitoring after thoracic radiotherapy in adults with thoracic tumors. The main question it aims to answer is: Dose dynamic monitoring of cardiac biomarkers, electrocardiography, echocardiography, peripheral blood immune cell subsets, cytokines, chemokines, lipid profiles, and lipid metabolism markers help identify early clinical or subclinical cardiac changes after thoracic radiotherapy? Are cardiac substructure radiation dose parameters associated with early cardiac safety outcomes? Participants receiving thoracic radiotherapy as part of their regular medical care will complete cardiac safety assessments at the end of radiotherapy, 1 month after radiotherapy, and 3 months after radiotherapy.

This is a prospective, single-arm, single-center exploratory clinical study designed to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) combined with QL1706 in patients with hepatocellular carcinoma who have received one prior line of systemic therapy and experienced radiographic disease progression or intolerance. Eligible patients will receive SBRT to all evaluable intrahepatic lesions at a total dose of 25-50 Gy delivered in 5 fractions. Within 7-14 days after completion of SBRT, patients will receive QL1706 at 7.5 mg/kg by intravenous infusion every 3 weeks. Treatment with QL1706 will continue until confirmed disease progression, intolerable toxicity, patient request to withdraw, withdrawal of informed consent, or other protocol-defined treatment discontinuation criteria, whichever occurs first. The primary endpoint is objective response rate assessed by the investigator according to modified RECIST criteria. Secondary endpoints include local control rate of SBRT target lesions, progression-free survival, overall survival, disease control rate, and the incidence of adverse events and serious adverse events. Exploratory endpoints include dynamic changes in serum tumor biomarkers and immune-related indicators, as well as their association with clinical outcomes. A total of 36 patients are planned for enrollment.

This is a single-arm, multicenter clinical study designed to evaluate the efficacy and safety of pyrotinib and trastuzumab combined with pegylated liposomal doxorubicin hydrochloride and cyclophosphamide followed by paclitaxel for injection albumin bound as neoadjuvant therapy in patients with early HER2-positive breast cancer. Eligible patients will receive 8 cycles of neoadjuvant treatment. Pyrotinib will be administered orally once daily, and trastuzumab will be administered intravenously every 3 weeks. During the first 4 cycles, patients will receive pegylated liposomal doxorubicin hydrochloride and cyclophosphamide. During the subsequent 4 cycles, patients will receive paclitaxel for injection albumin bound. The primary outcome is total pathological complete response rate. Secondary outcomes include breast pathological complete response rate, lymph node pathological complete response rate, objective response rate, event-free survival, distant disease-free survival, overall survival, and safety.

Provide a basis for selecting the treatment regimen for the confirmatory phase. 3. Explore the relationship between tumor tissue, stool, and blood biomarkers and efficacy and adverse reactions in liposomal irinotecan combination regimens versus irinotecan combination regimens. Phase III - Efficacy Confirmation Stage: Compare the efficacy and safety of liposomal irinotecan combination regimens versus irinotecan combination regimens in second-line treatment of metastatic colorectal cancer.

This study is a multicenter, retrospective, real-world cohort study. It retrospectively collected data from HER2-positive breast cancer patients who received neoadjuvant therapy with trastuzumab-containing chemotherapy regimens and had Non-pCR after surgery between July 2019 and July 2025. Patients were divided into two groups based on their adjuvant treatment regimens: the trastuzumab combined with pertuzumab group (HP) and the ado-trastuzumab emtansine group (T-DM1). The planned sample size is 2000 cases.

This is a multicenter, two-arm, exploratory clinical study designed to evaluate the efficacy and safety of a response-guided neoadjuvant treatment strategy in patients with HER2-positive early or locally advanced breast cancer. Breast cancer is the most common malignancy in women worldwide, and HER2-positive disease accounts for approximately 15-20% of cases and is associated with aggressive tumor biology and a higher risk of recurrence. The introduction of HER2-targeted therapies, including trastuzumab and pertuzumab, has significantly improved patient outcomes. However, a proportion of patients exhibit suboptimal response to standard neoadjuvant therapy, highlighting the need for more effective treatment strategies. In this study, approximately 100 eligible patients will be enrolled. All patients will initially receive 2 cycles of standard neoadjuvant therapy with trastuzumab, pertuzumab, and chemotherapy (THP or TCbHP). Tumor response will be assessed according to RECIST version 1.1 criteria. Patients with tumor reduction greater than 40% will continue the same regimen for an additional 4 cycles. Patients with tumor reduction of 40% or less will switch to an alternative regimen consisting of SHR-A1811, a novel HER2-targeted antibody-drug conjugate, in combination with pertuzumab for 4 cycles. SHR-A1811 is an investigational HER2-targeted antibody-drug conjugate designed to deliver a cytotoxic payload directly to tumor cells, potentially overcoming resistance to prior HER2-targeted therapies. Emerging clinical data have demonstrated promising anti-tumor activity and manageable safety in HER2-positive breast cancer. Clinical data, including baseline characteristics, imaging findings, and pathological markers such as Ki-67, will be collected throughout the study. Efficacy will be evaluated based on imaging assessments according to RECIST 1.1 criteria and pathological response at surgery, while safety will be monitored during treatment. The primary objective of this study is to explore whether switching to SHR-A1811 in combination with pertuzumab in patients with suboptimal early response can improve pathological complete response (pCR) rates. Secondary objectives include evaluation of safety and tolerability of the treatment strategies. This study aims to provide evidence for an individualized, response-adapted neoadjuvant treatment approach in HER2-positive breast cancer, and to optimize treatment outcomes for patients with inadequate response to standard therapy.

Brief Summary This is an open-label, randomized, phase II clinical study designed to evaluate neoadjuvant treatment regimens in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) early breast cancer. A total of 60 premenopausal, perimenopausal, and postmenopausal patients with HR+/HER2- breast cancer who meet the inclusion criteria will be enrolled. During the study, clinical information will be collected according to standard practice, including demographic data, tumor imaging, and pathological results (e.g., Ki-67). Investigator-assessed outcomes will be used as the final results. After 14 days of treatment, patients who provide consent will undergo a second biopsy to evaluate the rate of complete cell-cycle arrest. Safety assessments and imaging evaluations will be performed at treatment completion or upon study withdrawal. Informed consent must be obtained at each study center before participation. Treatment arms: Arm A (30 patients): Dalpiciclib 125 mg orally once daily on Days 1-21 of each 28-day cycle (3 weeks on, 1 week off), for 6 cycles Letrozole 2.5 mg orally once daily continuously for 6 cycles Entinostat 3 mg orally once weekly (Days 1-28 of each 28-day cycle), for 6 cycles Arm B (30 patients): Dalpiciclib 150 mg orally once daily on Days 1-21 of each 28-day cycle, for 6 cycles Letrozole 2.5 mg orally once daily continuously for 6 cycles Premenopausal and perimenopausal women will also receive ovarian function suppression (OFS), such as with a GnRHa agent. After signing informed consent, patients will begin neoadjuvant therapy with dalpiciclib plus entinostat and letrozole ± OFS. Ultrasound assessments will be conducted every two treatment cycles and before surgery under the same imaging conditions as baseline. Bone scans will be performed at the end of neoadjuvant treatment. MRI of the breast will be performed at baseline, after two cycles, and before surgery to assess treatment efficacy. Treatment discontinuation will occur if toxicity is intolerable, consent is withdrawn, or the investigator determines it is necessary. Adjuvant therapy: After surgery, patients will receive physician's choice of therapy (TPC). Safety follow-up: Patients will be followed until they start another anticancer therapy, all adverse events have resolved to Grade 0-1 or baseline level, or death-whichever occurs first.

Trilaciclib, an innovative first-in-class therapy that protects bone marrow at the source, has been approved for use in CDK4/6-independent small-cell lung cancer. However, clinical practice shows that patients with solid tumors frequently experience treatment-related pancytopenia involving neutrophils, erythroid lineage, and platelets after antineoplastic therapy, with a particularly high incidence of grade 3-4 myelosuppression. This poses serious threats to patient safety and delays the timely, standard administration of anticancer treatments. Therefore, it is imperative to investigate the expansion of trilaciclib's indications to solid tumors and its underlying mechanisms, and to establish a primary prophylaxis prediction model for solid tumor patients receiving chemotherapy. This study is designed in three parts: 1. Retrospective study: Collect real-world clinical data from patients with solid tumors who received trilaciclib for bone marrow protection during antineoplastic therapy, identify relevant multifactorial determinants, and use statistical methods to develop Primary Prophylaxis Prediction Model A. 2. Prospective study: Based on Model A, patients will be allocated into two experimental cohorts. Experimental Cohort 1: patients for whom primary prophylaxis with trilaciclib is indicated per Model A will receive primary prophylactic treatment. Experimental Cohort 2: patients for whom primary prophylaxis with trilaciclib is not indicated per Model A will receive secondary prophylaxis according to protocol. Outcomes will include the incidence of grade 3-4 myelosuppression, factors potentially influencing trilaciclib's marrow-protective effect, objective response rate (ORR) and progression-free survival (PFS) over 4-6 cycles, and changes in immunologic parameters. 3. Mechanistic exploration: Factors identified by the prediction model as influencing the need for trilaciclib primary prophylaxis will serve as mechanistic targets. Through in vivo and in vitro experiments using flow cytometry and single-cell sequencing, we will validate trilaciclib's bone marrow-protective effects across animal models of solid tumors with varying CDK4/6 dependence, and assess changes in tumor efficacy endpoints, T-lymphocyte subsets, and tumor immune microenvironment markers following trilaciclib monotherapy or combination with standard anticancer regimens.

This project is based on the in-depth analysis and integration of multi-omics data, including but not limited to genomics, transcriptomics, proteomics, and metabolomics. It aims to construct a comprehensive early-warning system for organ function damage in immune-related adverse events (irAEs) associated with immune checkpoint inhibitors (ICIs) during tumor immunotherapy. The core objective of this system is to enhance the overall safety and efficacy of tumor immunotherapy. First, the project leverages a database to mine the differential omics data of tumor immunotherapy patients with combined organ dysfunction (including combined and non-combined severe infections) within the scope of this project. By integrating biochemical indicators and related hemodynamic data, it constructs a risk early-warning system for organ damage in patients undergoing tumor immunotherapy, while verifying its clinical value and guiding significance. The specific contents mainly include: capturing specific molecules of organ damage in severe patients after tumor immunotherapy, screening genes, proteins, and metabolic products related to organ damage (including the heart, lungs, brain, liver, kidneys, gastrointestinal tract, etc.), and identifying new specific organ damage biomarkers under different pathogenic factors such as tumor immunotherapy, infections, and irAEs. It collects general clinical information, biochemical indicators, and hemodynamic indicators, and combines multi-omics data to establish an organ damage prediction model. Machine learning algorithms are used for optimization to construct an early-warning system. Model optimization within the system will be carried out, along with prospective clinical research and multi-dimensional verification. By evaluating the accuracy and cost-effectiveness of the model, it provides decision-making support for clinicians and promotes the development of personalized treatment.
