Clinical trials

This is a prospective, single-arm Phase 2 study to evaluate the efficacy and safety of sintilimab combined with anlotinib and taxane-based chemotherapy in patients with recurrent (not unable to locally curative treatment) or metastatic NPC who failed at least first-line platinum-containing standard regimen and/or anti PD-1/L1.

This study is a randomized, open-label, multicenter phase III trial designed to systematically evaluate the efficacy and safety of perioperative neoadjuvant and adjuvant therapy with Becotatug vedotin in combination with PD-1 inhibitor versus PD-1 inhibitor alone in patients with EGFR-positive, CPS ≥ 1 resectable locally advanced head and neck squamous cell carcinoma .

The combination of local consolidative therapy for oligometastases with systemic therapy offers the potential for clinical cure and significantly prolongs survival in a subset of patients with advanced metastatic disease. However, a considerable proportion of patients still do not benefit from this approach. Becotatug vedotin (MRG003) is an antibody-drug conjugate that carries the payload monomethyl auristatin E (MMAE), a microtubule inhibitor. MMAE has been shown to effectively enhance radiosensitivity in various preclinical tumor models, including head and neck squamous cell carcinoma, liver cancer, gastric cancer, pancreatic cancer, and lung cancer. Furthermore, multiple clinical studies have demonstrated the promising therapeutic potential of vicetuximab in EGFR-positive solid tumors. Based on this background, we plan to conduct a clinical study evaluating the combination of stereotactic body radiotherapy (SBRT) for oligometastases with investigator-selected systemic therapy and Becotatug vedotin (MRG003) in patients with EGFR-positive oligometastatic tumors.

This study aims to explore the efficacy and adverse events of reduced-dose radiotherapy (40.2Gy) versus conventional-dose radiotherapy (49.2Gy) to low-risk target volume for chemosensitive intermediate-stage nasopharyngeal carcinoma patients.

To explore the efficacy and safety of reduced-dose radiotherapy combined with concurrent chemotherapy and immunotherapy in stage Ⅳa (AJCC 8th,) locally advanced nasopharyngeal carcinoma patients who are sensitive to induction chemoimmunotherapy (assessed as complete response \[CR\]/partial response \[PR\] by imaging, with EBV DNA copy number reduced to zero or below the lower limit of detection), so as to provide a new treatment option for these patients.

In order to further verify the effectiveness of the new prevention irradiation model for low-risk areas for nasopharyngeal carcinoma under immunotherapy, our team intends to conduct a non-inferiority clinical trial. The aim is to evaluate the efficacy and safety of two treatment modalities - local region reduced-target radiotherapy versus full-target radiatiotherapy (with/without CTV2) for newly diagnosed distant metastasis nasopharyngeal carcinoma, based on the full-course immunotherapy and full-dose chemotherapy. The primary endpoints are 2-year PFS and the incidence of grade 3 or higher radiation-related adverse events. If non-inferiority is confirmed, a new standard of "immunotherapy combined with reduced-target radiotherapy" will be established, ensuring efficacy while significantly reducing toxicity, and providing a more optimal comprehensive treatment strategy for nasopharyngeal carcinoma.

This is a prospective, Bayesian adaptive, phase II clinical trial designed to evaluate the safety and efficacy of four treatment regimens in patients with recurrent (unamenable to local therapy) or metastatic nasopharyngeal carcinoma (NPC) who have failed after at least one prior platinum-containing standard regimen and anti-PD-1/PD-L1 therapy. The four treatment arms include: 1. Ivonescimab monotherapy, 2. Ivonescimab combined with nimotuzumab, 3. Liposomal mitoxantrone plus anti-PD-1 antibody, and 4. Liposomal irinotecan plus S-1.

This study is a prospective, self-controlled, multicenter clinical trial. All participants will be tested for Epstein-Barr virus (EBV) associated biomarkers, including the two-antibody method (VCA-IgA and EBNA1-IgA), BNLF2b total antibodies (P85-Ab), and plasma EBV DNA. Furthermore, novel screening biomarkers, such as next-generation sequencing for EBV and castoff cells using nasopharyngeal swabs, will be explored. First, it aims to investigate whether plasma EBV DNA testing or the P85-Ab testing can achieve higher sensitivity than the current standard two-antibody method testing while maintaining specificity in NPC screening, thereby identifying the optimal initial NPC screening strategy. Based on the determined optimal initial screening strategy, the study will validate the proposed two-step method (subjects first undergo two-antibody method testing and P85-Ab testing; those positive for either one biomarker above proceed to plasma EBV DNA testing; subjects positive in both steps are defined as high-risk and receive endoscopic examinations with or without biopsy) compared with the single-step method (subjects simultaneously undergo two-antibody method testing, P85-Ab testing, and plasma EBV DNA testing; subjects with any positive biomarker undergo endoscopic examinations with or without biopsy) and each single screening testing. The aim is to determine whether two-step method can further improve the positive predictive value (PPV) while maintaining non-inferior sensitivity, thereby enhancing screening efficiency, reducing the rate of invasive procedures (such as endoscopic biopsies), and lowering medical costs and insurance burdens.

This is a prospective, single-arm Phase 2 study to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection combined with PD-1 blockade in patients with recurrent (not unable to locally curative treatment) or metastatic NPC who failed at least first-line platinum-containing standard regimen and/or anti PD-1/L1.

The goal of this clinical trial is to compare the efficacy and safety of endoscopic nasopharyngectomy combined with retropharyngeal lymph nodes dissection plus bilateral upper neck lymph node dissection or plus postoperative low-dose radiotherapy in newly diagnosed stage Ⅰ nasopharyngeal carcinoma.

The goal of this clinical trial is to compare surgery plus reduced target chemoradiotherapy with surgery plus reduced dose chemoradiotherapy in newly diagnosed operable Nasopharyngeal Carcinoma.The main questions it aims to answer are:whether endoscopic surgery combined with reduced dose chemoradiotherapy vs surgery plus target reduction chemoradiotherapy can bring substantial survival benefits, lower toxicity, and shorter treatment cycle for patients with operable nasopharyngeal carcinoma .
