Nasopharyngeal Cancinoma (NPC)

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 .

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.

This study aims to evaluate the efficacy and toxicity of adding low-dose radiotherapy to chemoimmunotherapy as a first-line treatment for nasopharyngeal carcinoma patients with liver metastasis.

This randomized trial evaluates a multimodal surveillance strategy in nasopharyngeal carcinoma patients with high-risk N3 cervical lymph node involvement after radiotherapy. Patients are assigned to standard follow-up or an enhanced strategy using CEUS, imaging, and EBV DNA for risk assessment. The intervention group uses multimodal evaluation to identify high-risk patients who may undergo multidisciplinary review and selective neck dissection when indicated. The primary endpoint is failure-free survival (FFS). Secondary endpoints include OS, LRRFS, DMFS, 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.

This is a prospective, single-arm, phase II clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of EGFR antibody combined with programmed death 1 (PD-1) antibody and chemotherapy in recurrent/metastatic nasopharyngeal carcinoma patients.

The goal of this international, multicenter, prospective observational study is to improve prognostication and prediction of failure pattern for nasopharyngeal carcinoma (NPC), in order to provide more accurate guidance for personalized treatment decision. Firstly, we aim to improve the fundamental TNM staging system \[The American Joint Committee on Cancer(AJCC)/Union for International Cancer Control(UICC) TNM Version-Nine\] based on universally assessable anatomical parameters. Secondly, we aim to further refine prognostication for individual patients by integrating anatomical TNM parameters with non-anatomical factors and molecular biomarkers. In addition to the core group of participating centers from China (including Hong Kong) where NPC is most prevalent, the study will enrol patients from multiple countries/regions including those from non-endemic areas to provide global data. Patients treated with contemplary treatment methods during October 2025 to September 2026 will be recruited and they will be followed up for 5 years to generate detailed records for robust evaluation. Key Questions: * To achieve optimal improvement of anatomically based AJCC/UICC TNM Classification for global application * To achieve precise prediction of failure pattern for individual patients by integration of TNM system and non-anatomical prognostic factors/molecular biomarkers Recruited patients with confirmed histological diagnosis of NPC will undergo standard clinical evaluations and receive treatment per institutional guidelines. The anatomical extent of disease at presentation will be evaluated by experienced radiologists and oncologists. The patient will be followed up for 5 years and clinical outcome will be recorded for analyses on correlation with prognostic factors. This study will be another important milestone for NPC staging because firstly, this is the first time that the data are based on prospective data to ensure comprehensive coverage of all essential evidence; and secondly, this is the first time that centers from non-endemic countries/regions will also participate to ensure that the final recommendations are globally applicable. The findings will provide valuable evidence for the development of the AJCC/UICC TNM Version-Ten staging system and prognostic system to improve risk stratification for designing personalized treatment strategy, ultimately leading to improvement of patient outcome and patient selection for future research worldwide.

Based on the short-term efficacy and plasma EBV DNA levels following immuno-induction chemotherapy, patients with locally advanced nasopharyngeal carcinoma who derive different benefits from this treatment can be identified. For high-risk patients who do not respond to immuno-induction chemotherapy (defined as EBV DNA \>0 copies/mL or imaging response evaluation showing SD/PD after immuno-induction chemotherapy), the addition of becotatug vedotin, which has a different mechanism of action, during concurrent radiotherapy and the adjuvant phase may improve patient survival. Based on the above research and background, the investigators plan to conduct the first prospective, single-arm, phase II clinical study of becotatug vedotin in patients with locally advanced nasopharyngeal carcinoma who are suboptimal responsive to immuno-induction chemotherapy, aiming to obtain sufficient evidence-based medical data to provide an additional treatment option for the concurrent and adjuvant phases of nasopharyngeal carcinoma.

This randomized controlled trial aims to evaluate the efficacy and safety of Becotatug Vedotin (MRG003), an antibody-drug conjugate (ADC), combined with the PD-1 inhibitor Pucotenlimab as induction therapy for high-risk locoregionally advanced nasopharyngeal carcinoma (NPC), compared to the standard gemcitabine and cisplatin (GP) regimen combined with Pucotenlimab, followed by concurrent chemoradiotherapy (CCRT) and adjuvant immunotherapy.

This observational study aims to evaluate the efficacy and safety of intensity-modulated radiotherapy (IMRT) alone in patients with stage IB nasopharyngeal carcinoma (NPC) without high-risk features. The primary objective is to determine the therapeutic effectiveness of this approach

This trial aim to explore whether short-course tislelizumab (3 cycles of 200 mg q3w in the induction phase and 3 cycles of 400 mg q6w in the consolidation phase) yields non-inferior event-free survival compared to long-course tislelizumab (3 cycles of 200 mg q3w in the induction phase and 5 cycles of 400 mg q6w in the consolidation phase) in patients with locoregionally advanced nasopharyngeal carcinoma.

1. To assess whether radiotherapy alone is non-inferior to concurrent chemoradiotherapy with respect to event-free survival and superior in reducing treatment-related nausea in low-risk locoregionally advanced nasopharyngeal carcinoma patients who achieve complete or partial response and undetectable serum EBV-DNA following induction chemoimmunotherapy. 2. To evaluate whether adjuvant capecitabine and immunotherapy after concurrent chemoradiotherapy improves event-free survival compared to adjuvant immunotherapy in high-risk locoregionally advanced nasopharyngeal carcinoma patients with stable disease or detectable serum EBV-DNA after induction chemoimmunotherapy.

The goal of this phase 3 non-inferiority trial is to compare the efficacy and toxicity of proton or photon radiation therapy plus carbon ion radiation therapy for newly diagnosed nasopharyngeal carcinoma. The main question it aims to answer is that if proton radiation therapy plus carbon ion radiation therapy is non-inferior to photon radiation therapy plus carbon ion radiation therapy in terms of therapeutic efficacy. Participants will be randomized to receive either proton radiation therapy (arm 1) or photon radiation therapy (arm 2), in addition to carbon ion radiation therapy (for both arms).

To prospectively investigate and integrate radiomic and immunologic signatures in patients with nasopharyngeal carcinoma (NPC) treated with either proton or photon radiotherapy, with the aim of identifying biomarkers associated with treatment response, toxicity, and long-term outcomes.

This trial evaluated the efficacy of two adjuvant regimens following identical induction and concurrent chemoradiotherapy (IC+CCRT) in locoregionally advanced nasopharyngeal carcinoma (LANPC) patients with persistent EBV DNA positivity or stable disease after three IC cycles. The control arm received adjuvant adebrelimab, while the experimental arm received adebrelimab plus capecitabine.

Nasopharyngeal carcinoma (NPC) is an endemic malignancy in Southern China and southeast Asia. Despite intensive radical therapy, between 15% and 30% of NPC patients develop relapse. Recent phase III randomized-controlled trials conducted in China demonstrated an improvement of progression-free survival with combinational therapy immune checkpoint inhibitors (ICI) (camrelizumab, toripalimab, and tislelizumab, respective) and chemotherapy gemcitabine (G) and cisplatin (P) compared with chemotherapy GP alone for recurrent or metastatic NPC. However, none of these studies have described in details the treatment outcomes of those subjects with locally recurrent NPC only, and whether any of these patients would undergo radical surgery to remove the residual locally recurrent NPC after ICI and chemotherapy. Continuation of the same ICI as maintenance therapy may only be the treatment option for these patients who were recruited into these phase III trials, unless if they withdrew from the study and opted for radical resection. While continuing the same ICI may still lead to persistent objective response and disease control, there is a possibility of tumor recurrence leading to unresectable disease and a worse survival outcome, or unexpected, rare but recognized immune-related emergent adverse events with ICI. Radical resection after maximal response to ICI and chemotherapy for patients with locally recurrent NPC only may provide a chance of cure of the disease and these patients may be obviated from continuous exposure to ICI therapy. In view of the above, we are now proposing a phase II single-arm study on perioperative pembrolizumab and chemotherapy followed by radical surgery for locally recurrent NPC. As a collateral study, we will also perform single-cell DNA and RNA sequencing and proteomics study to observe the tumor and immune microenvironment which certainly helps us decipher the mechanisms of tumor response at genomic, transcriptomic and proteomic levels.

Nearly all undifferentiated nasopharyngeal carcinoma (NPC) are associated with the Epstein-Barr Virus (EBV), which typically remains in a latent, non-immunogenic state within tumor cells. By combining EBV lytic induction strategy with standard chemo-immunotherapy, this study aims to create a synergistic anti-tumor effect and improve clinical outcomes for patients with recurrent/metastatic NPC (r/m NPC). This is a phase II, single-center, single-arm clinical trial designed to evaluate the efficacy and safety of a novel combination therapy in patients with r/m EBV-positive NPC.

This single-arm, phase 2 trial evaluates the efficacy and safety of de-escalated radiotherapy (restricted to the primary tumor, omitting prophylactic neck irradiation) combined with neoadjuvant and adjuvant toripalimab immunotherapy, and concurrent chemotherapy in patients with nasopharyngeal carcinoma staged N0 or N1, where nodal involvement is strictly confined to the retropharyngeal lymph nodes.
