Clinical trials

This three-arm parallel randomized controlled trial aims to evaluate the effectiveness of VIPeerAgent, a virtual peer support agent, in improving mental health outcomes among adolescents and young adults aged 14-25 years experiencing psychological distress without a diagnosed mental disorder. Participants will be randomized to receive support from VIPeerAgent, a human peer mentor, or usual care. The study will assess whether VIPeerAgent is non-inferior to human peer support and superior to usual care in promoting mental health. Outcomes include mental health status, psychological resilience, coping strategies, perceived social support, and emotional intelligence. The findings will provide evidence for the effectiveness and scalability of AI-assisted peer support as an early intervention approach for youth mental health.

This study is a randomized, open-label, controlled phase II clinical trial. It is planned to enroll 176 subjects with platinum-sensitive recurrent epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer previously treated with Poly (ADP-ribose) polymerase inhibitors (PARPi). Subjects will be randomly assigned in a 1:1 ratio to receive either the experimental treatment group (trastuzumab Rezetecan + carboplatin ± bevacizumab) or the control treatment group (investigator's choice chemotherapy ± bevacizumab).

This study is a prospective, single-arm clinical trial with a dose-reduction design, which is expected to enrol 18 patients with locally advanced rectal cancer with pMMR status. The aim is to investigate the safety and efficacy of neoadjuvant chemoradiotherapy combined with sintilimab and suvecitib. Patients will receive long-course chemoradiotherapy (concurrent capecitabine, 1000 mg/m², twice daily, days 1-14, Q3W, 2 cycles; sintilimab, 200 mg, d1, IV drip, Q3W, 2 cycles), followed by 6 cycles of the Capeox regimen in combination with sintilimab and suvecitib, namely oxaliplatin 130 mg/m², d1, IV infusion, every 3 weeks; and capecitabine 1,000 mg/m², twice daily, days 1-14, every 3 weeks; sintilimab, 200 mg, Day 1, IV drip, every 3 weeks; suvectitumab (anti-angiogenic agent), 2.0/1.5/1.0 mg/kg, Day 1, IV drip, every 3 weeks. A total of 8 cycles of sintilimab and 6 cycles of suvectitumab were administered during the neoadjuvant treatment period. If, following completion of neoadjuvant therapy, the subject has not achieved cCR/near-cCR status, TME surgery or other therapeutic surgery shall be performed; the interval between the final dose of suvectitumab and surgery should be ≥6 weeks. If cCR/near-cCR status is achieved, watchful waiting or other treatment options shall be discussed with the patient. The adjuvant treatment regimen following surgery shall be determined by the investigator based on the patient's pathological results.

Functional mitral regurgitation is a highly dynamic disease. Some patients exhibit only moderate(2+) functional mitral regurgitation at rest, which deteriorates to moderate-to-severe or severe FMR(3+ or 4+) during stress-termed dynamic severe functional mitral regurgitation. Observational studies link this condition to worse outcomes, with mitral valve intervention offering potential benefits; however, high-quality evidence remains lacking. The Transcatheter Edge-to-Edge Repair In DynaMic sEvere Functional Mitral Regurgitation trial aims to assess the safety and effectiveness of transcatheter edge-to-edge repair plus guideline-directed medical therapy versus guideline-directed medical therapy alone in symptomatic chronic heart failure patients with dynamic severe functional mitral regurgitation, defined as moderate regurgitation at rest deteriorating to severe during handgrip stress echocardiography. This prospective, multi-center, randomized trial enrolls patients with dynamic severe functional mitral regurgitation confirmed by a core laboratory using handgrip stress echocardiography. Patients are randomized 1:1 to transcatheter edge-to-edge repair plus medical therapy or medical therapy alone. The primary endpoint is the composite of Cardiovascular death or heart failure hospitalization over the entire period. This trial will provide critical evidence on transcatheter edge-to-edge repair in patients with dynamic severe functional mitral regurgitation, informing future treatment recommendations.

This study aims to evaluate whether plasma molecular residual disease (MRD), assessed using circulating tumor DNA (ctDNA), can help optimize the duration of immunotherapy in patients with metastatic microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) colorectal cancer. Patients with MSI-H/dMMR metastatic colorectal cancer can achieve durable responses to immune checkpoint inhibitors, but the optimal duration of treatment remains uncertain. Prolonged immunotherapy may increase treatment burden and the risk of immune-related adverse events. ctDNA-based MRD testing may provide a sensitive method for detecting residual tumor burden and identifying patients who may be able to safely stop treatment. In this study, patients receiving immunotherapy will undergo serial plasma MRD testing. After completing 1 year of immunotherapy, patients with two consecutive negative MRD results will be randomly assigned to either continue immunotherapy or stop treatment and enter observation. Patients will then be followed every 3 months for 2 years with MRD testing and routine clinical assessments, including imaging and laboratory examinations. The study will compare clinical outcomes between the two groups and evaluate whether serial plasma MRD monitoring can support a more individualized approach to the duration of immunotherapy in MSI-H/dMMR metastatic colorectal cancer.

This is a non-inferiority, multicenter, randomized phase 3 trial aimed to evaluate whether primary clinical target volume (CTVp) delineation based on margin expansion provides comparable outcomes compared with the consensus CTVp approach based on margin expansion and the stepwise extension pattern in newly diagnosed non-metastatic nasopharyngeal carcinoma.

This is an open-label, multicenter, single-arm Phase 2 clinical trial evaluating neoadjuvant pucotenlimab (anti-PD-1 immunotherapy) combined with becotatug vedotin (EGFR-targeted antibody-drug conjugate, ADC) for adults with locally advanced penile squamous cell carcinoma. Eligible patients have high-risk disease defined as T4 primary tumor with any nodal status or any T stage with N2-N3 lymph node metastasis and no distant metastasis. All participants receive up to 4 cycles of combination neoadjuvant therapy every 3 weeks. After treatment completion, a multidisciplinary team will assess if consolidative surgery can be performed. Patients who undergo surgery will continue single-agent pucotenlimab adjuvant treatment for 17 additional cycles (approximately 1 year). The primary goal is to measure the pathological complete response (pCR) rate. Secondary goals include objective response rate (ORR), progression-free survival (PFS),overall survival (OS) and safty profiles. Blood and tumor tissue samples will be collected to explore biomarkers that may predict treatment response and drug resistance. A total of 29 male patients will be enrolled.

This study aims to evaluate whether the combination of Megestrol Acetate at the initiation of Trastuzumab Deruxtecan (T-DXd) treatment can effectively prevent and alleviate T-DXd-related fatigue, thereby improving the quality of life for advanced breast cancer patients.

This is a phase 2, open-label, single-arm clinical trial evaluating neoadjuvant therapy with Becotatug vedotin (MRG003) combined with Pucotenlimab (HX008) in patients with previously untreated, resectable stage III-IVA oral cavity squamous cell carcinoma (OSCC) with a PD-L1 Combined Positive Score (CPS) of 1 or higher. Eligible participants will receive 3 cycles of neoadjuvant treatment (Becotatug vedotin 2.3 mg/kg plus Pucotenlimab 200 mg, intravenously, every 3 weeks), followed by radical surgery 2-3 weeks after the last cycle of neoadjuvant therapy. Postoperative adjuvant radiotherapy will be stratified based on pathological response and risk factors: patients achieving major pathological response (MPR, defined as ≤10% residual viable tumor) with negative margins and no extranodal extension (ENE) will receive de-escalated radiotherapy (50-54 Gy); patients not achieving MPR or with high-risk features will receive standard radiotherapy (60-66 Gy) with or without concurrent cisplatin chemotherapy. The primary endpoint is major pathological response (MPR). Secondary endpoints include objective response rate (ORR), pathological complete response (pCR), event-free survival (EFS), overall survival (OS), and safety profile. Exploratory biomarkers will be assessed in tumor tissue and peripheral blood. A total of 32-33 participants will be enrolled using a Simon two-stage optimal design (α=0.05, power=80%).

The RADIANCE trial plans to enroll patients with chemotherapy-ineligible de novo metastatic nasopharyngeal carcinoma (AJCC 9th edition, TxNxM1). Participants will receive Radscopal radiotherapy, consisting of low-dose radiotherapy to the primary lesions and stereotactic body radiotherapy to distant metastatic lesions, in combination with sintilimab and ipilimumab. The study will evaluate the objective response rate of the primary lesions, systemic disease control as measured by progression-free survival and overall survival, and the safety and tolerability of this treatment regimen. The main questions this study aims to answer are: Does this treatment improve efficacy with acceptable safety in chemotherapy-ineligible patients? Does Radscopal radiotherapy enhance systemic antitumor immunity, and what is the Radscopal Response Rate? What clinical and immunological factors are associated with the Radscopal effect, and what mechanisms may underlie this effect?

This study evaluates the combination of the autophagy inhibitor hydroxychloroquine (HCQ), the MEK inhibitor tunlametinib, and the anti-PD-1 antibody pucotenlimab in patients with locally advanced or metastatic melanoma. The primary objectives are to assess the objective response rate (ORR) and progression-free survival (PFS). Secondary objectives include evaluating adverse events (type, severity, and incidence), duration of response (DOR), disease control rate (DCR), and overall survival (OS), as well as exploring the molecular mechanisms by which autophagy modulation enhances immunogenicity in mutant melanoma. Further exploratory analyses will examine the mechanisms by which autophagy inhibition enhances tumor sensitivity to PD-1 blockade, thereby establishing experimental and theoretical grounds for refining future clinical approaches.

This study aims to evaluate the efficacy and safety of adding the anti-angiogenic agent anlotinib to the combination of the CDK2/4/6 inhibitor Culmerciclib and endocrine therapy in patients with HR+/HER2- breast cancer and brain metastases. Eligible patients present with newly diagnosed brain metastases or brain metastases that progressed following prior local therapy. It is hoped that this therapeutic combination can achieve disease control in these patients.

This is a phase II, multicenter, open-label, single-arm clinical study. The purpose of this study is to evaluate the efficacy and safety of culmerciclib combined with anti-HER2 targeted therapy and endocrine therapy as maintenance treatment in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer. Culmerciclib is a novel oral cyclin-dependent kinase 2/4/6 (CDK2/4/6) inhibitor. It has been approved in China for use in combination with fulvestrant in patients with HR-positive, HER2-negative advanced breast cancer who have progressed on prior endocrine therapy. Patients enrolled in this study will receive culmerciclib at a stepwise escalating dose of 120 mg, 150 mg, and 180 mg once daily, in combination with anti-HER2 therapy (trastuzumab with or without pertuzumab) and physician-selected endocrine therapy. Treatment will continue until disease progression, unacceptable toxicity, death, withdrawal of consent, or loss to follow-up. The primary endpoint is progression-free survival. Secondary endpoints include objective response rate, disease control rate, clinical benefit rate, overall survival, and safety.

The primary endpoint is PFS. Secondary endpoint includes overall survival, objective response rate, safety profiles, immune-related adverse events, and patient quality of life. Exploratory analyses focus on dynamic shifts in tumour immune microenvironment and biomarkers, aiming to identify predictive signatures for therapeutic efficacy and immune toxicities.

The goal of this interventional study (clinical trial) is to evaluate the efficacy and safety of adding dapagliflozin to first-line standard therapy in patients with unresectable hepatocellular carcinoma (HCC) and comorbid metabolic syndrome. The main questions it aims to answer are: Does the addition of dapagliflozin to first-line therapy improve the objective response rate (ORR) compared with first-line therapy alone in this patient population? What are the differences between the two treatment groups in terms of overall survival (OS), progression-free survival (PFS), and safety/tolerability profiles? Researchers will compare the combination group (dapagliflozin plus first-line standard therapy) with the control group (first-line standard therapy alone) to determine whether the addition of dapagliflozin provides superior clinical benefit. Participants in the combination group will receive dapagliflozin in addition to their prescribed first-line standard therapy, while participants in the control group will receive first-line standard therapy alone. All participants will be regularly monitored for tumor response, survival outcomes, and adverse events throughout the study period. The findings of this trial are expected to provide clinical evidence supporting the use of dapagliflozin as an adjunctive therapy in patients with advanced unresectable HCC and metabolic syndrome, potentially enhancing the tumor response rate to existing standard-of-care treatments.

Re-irradiation is the most common clinical treatment for recurrent nasopharyngeal carcinoma; however, it is associated with severe complications which seriously affect patients' quality of life. Exploring deferred salvage radiotherapy until nasopharyngeal or cervical progression after PD 1 plus GP chemotherapy and immunotherapy maintenance is of great significance for improving the long-term survival and quality of life of patients with unresectable locally recurrent NPC. Thus, the investigators plan to conduct a multicenter, prospective, single-arm phase II clinical trial to evaluate the efficacy and safety of maintenance Immunotherapy with deferred salvage radiotherapy with an objective response to chemoimmunotherapy in patients with unresectable locally recurrent NPC .

To evaluate the efficacy of celecoxib combined with R-CHOP versus R-CHOP in the treatment of newly diagnosed advanced CD5-positive diffuse large B-cell lymphoma (CD5+ DLBCL).The primary endpoint is Complete Response Rate (CRR)

This study investigated the efficacy and safety of Tunlametinib Combination Therapy in the Treatment of Second-line and Above Metastatic Colorectal Cancer.

Immunotherapy combined with chemoradiotherapy has become standard care for locally advanced nasopharyngeal carcinoma, yet radiotherapy-induced lymphopenia may impair the efficacy of concurrent PD-1 blockade. Existing evidence supports synergistic anti-tumor activity between the anti-EGFR antibody nimotuzumab and toripalimab. This multicenter, open-label, non-inferiority Phase III trial randomizes eligible stage III-IVA LA-NPC patients 1:1 to two arms. The experimental group receives an "immune sandwich" regimen: TPC induction plus nimotuzumab and toripalimab, concurrent radiotherapy with weekly nimotuzumab only, followed by toripalimab maintenance. The control arm adopts full-course toripalimab throughout induction, concurrent radiotherapy and adjuvant phases. The primary endpoint is 3-year event-free survival, with secondary endpoints covering overall survival, local/distant control rates, objective response rate and treatment-related toxicities. A total of 566 subjects will be enrolled to verify whether the simplified sandwich strategy delivers non-inferior survival with better safety profiles.

This trial aims to study the role of Ivonescimab combined with chemoradiotherapy in high-Risk locoregionally advanced nasopharyngeal carcinoma.

This is a prospective, multicenter, randomized, open-label, umbrella superiority clinical trial for patients with advanced metastatic esophageal squamous cell carcinoma who have not received prior anti-tumor treatment. All eligible participants will be randomly assigned into two cohorts: Cohort A (standard treatment group) and Cohort B (biomarker-guided precision treatment group). Patients in Cohort A will receive first-line standard therapy consisting of TP chemotherapy plus PD-1 inhibitor. All patients in Cohort B will first complete three biomarker tests, then be divided into 4 sub-groups based on biomarker results to receive biomarker-directed additional treatment combined with the same standard backbone therapy. Participants with all negative biomarkers or failed biomarker testing will receive the identical standard treatment as Cohort A. The primary objective is to compare the survival benefit between biomarker-guided multi-strategy precision therapy and conventional standard first-line treatment.

This multicenter randomized controlled Phase III trial assesses the efficacy and safety of becotatug vedotin plus anti-PD-1 antibody as maintenance therapy for recurrent/metastatic nasopharyngeal carcinoma. Eligible patients aged 18-75 must have stable disease or positive plasma EBV DNA after 4-6 cycles of first-line chemoimmunotherapy, with adequate organ function and good physical status. A total of 86 subjects will be randomly split 1:1: the control group receives single anti-PD-1 maintenance, while the experimental group gets anti-PD-1 combined with becotatug vedotin in 21-day cycles for up to 2 years. Regular blood tests and tumor scans will be performed to monitor efficacy and adverse events graded by CTCAE v5.0; biological samples will be collected for biomarker research with consent. The primary endpoint is IRC-reviewed progression-free survival, with secondary endpoints covering overall survival, tumor response rates and safety. Overseen by an independent ethics committee, the trial ensures full data confidentiality. Participants sign informed consent and can withdraw anytime without interference to their routine cancer care, exploring a superior maintenance regimen for this high-risk NPC group.
