Efficacy and Safety of Becotatug Vedotin (MRG003) Combined With Anti-PD1 as Maintenance Therapy for Recurrent and Metastatic Nasopharyngeal Carcinoma

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.

Participants will receive standard chemoradiotherapy. After treatment, they will undergo follow-up evaluation using clinical assessment, conventional imaging, Epstein-Barr virus DNA testing, and contrast-enhanced ultrasound. Participants with clinically suspicious residual cervical lymph nodes identified by multimodal evaluation and eligible for surgery underwent endoscopic selective neck dissection.

International Collaborative Study on AJCC/UICC TNM-10 for Nasopharyngeal Cancer

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.

Becotatug Vedotin for LA-NPC With a Suboptimal Response to Induction Chemotherapy Combined With Immunotherapy

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.
