About this study

Official title: Becotatug Vedotin Combined With Sintilimab and Chemoradiotherapy in Locoregionally Advanced Nasopharyngeal Carcinoma:A Multicenter, Randomized, Controlled, Phase 3 Trial

This study is a multicenter, randomized, controlled phase III clinical trial aiming to investigate the efficacy and safety of Becotatug Vedotin induction therapy followed by concurrent chemoradiotherapy (CCRT) combined with neoadjuvant and adjuvant sintilimab, versus gemcitabine plus cisplatin (GP) induction chemotherapy followed by CCRT, in the treatment of high-risk locally advanced nasopharyngeal carcinoma (LANPC). The study plans to enroll 266 patients with high-risk NPC (AJCC 9th edition, anyT N2-3M0 or T4N1M0), who will be randomly assigned to the experimental group or the control group at a 1:1 ratio.The primary endpoint is 3-year event-free survival (EFS), and the secondary endpoints include overall survival (OS), local-regional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), objective response rate (ORR), adverse events, and quality of life.

Read the detailed description

This is a multicenter, randomized, controlled phase III clinical study targeting patients with high-risk locally advanced nasopharyngeal carcinoma (stage T1-4N2-3M0 or T4N1M0 per the 9th AJCC/UICC staging system), with a planned enrollment of 266 patients who will be randomized 1:1 into an experimental group and a control group under an open-label, stratified randomization design. The primary endpoint of the study is 3-year event-free survival (EFS), and the secondary endpoints include efficacy measures such as overall survival and locoregional recurrence-free survival, as well as safety and quality of life assessments; additionally, the study explores the predictive value of efficacy biomarkers including EGFR expression and combined positive score (CPS). The experimental group is administered neoadjuvant therapy with becotatug vedotin plus sintilimab for 3 cycles, followed by concurrent chemoradiotherapy with cisplatin combined with adjuvant sintilimab therapy for 9 cycles, while the control group receives induction chemotherapy with gemcitabine plus cisplatin (GP regimen) for 3 cycles followed by concurrent chemoradiotherapy with cisplatin. Intensity-modulated radiation therapy (IMRT) is uniformly adopted for all patients in both groups, with standardized target volume doses and normal organ dose constraints defined. The study has also formulated detailed protocols for drug dose adjustment and toxicity monitoring; treatment-related adverse events are graded and managed in accordance with the NCI-CTCAE v5.0 and RTOG/EORTC criteria, and the EORTC QLQ-C30 scale is used to evaluate patients' quality of life. The study aims to verify that the innovative treatment regimen of becotatug vedotin combined with sintilimab yields superior efficacy with a manageable safety profile compared with the conventional GP induction chemotherapy followed by chemoradiotherapy in patients with high-risk locally advanced nasopharyngeal carcinoma, thereby providing a novel treatment option for this patient population and supplementing high-level evidence-based medical evidence. Meanwhile, it explores relevant biomarkers to lay a foundation for individualized treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Event-free survival (EFS)

    The time interval from randomization to the first treatment failure or the last follow-up if there is no treatment failure. Treatment failure is defined as local/cervical residual disease 16 weeks after radiotherapy, local/cervical recurrence, distant metastasis, or death due to any cause,whichever occurred first.

    Measured: 3 years

Secondary outcomes (6)
  1. Overall survival (OS)

    The time interval from randomization to the date of death from any cause.

    Measured: 3 years

  2. Distant metastasis-free survival (DMFS)

    The time interval from randomization to the date of first distant metastasis, or death from any cause, whichever occurred first.

    Measured: 3 years

  3. Locoregional recurrence-free survival (LRFS)

    The time interval randomization to the date of locoregional persistence, 1st locoregional recurrence, or death from any cause, whichever occurred first.

    Measured: 3 years

  4. Adverse events (AEs) and serious adverse events (SAEs)

    Graded according to CTCAE V5.0.

    Measured: 3 years

  5. Quality of life (QoL)

    The change of QoL from randomization to the start of radiotherapy,the 16th fraction of radiotherapy, the end of radiotherapy, 43 weeks (at the end of sintilimab treatment in the sintilimab arm and the corresponding timepoint in the chemoradiation arm). The EORTC QoL questionnaire-C30 (EORTC QLQ-C30)version 3.0 will be used. This questionnaire comprises 30 questions, 24 of which are aggregated into nine multi-question scales, that is, five functioning scales (e.g., physical), three symptom scales (e.g., fatigue) and one global health status scale. The remaining six single-question (e.g., dyspnoea) scales assess symptoms. These 15 scales will be scored according to the official Scoring Manual.

    Measured: 3 years

  6. Event-free survival (EFS) within different subgroups

    analyses for EFS will be performed within the following subgroups: Epstein-Barr virus (EBV) DNA (<4000copies/ml vs. ≥4000copies/ml), EGFR expression status (positive vs negative), different PD-L1 expression levels (<1% vs. ≥1%), tertiary lymphoid structure (+ vs. -), age, gender, performance status, T category, N category, and stage (II vs. III).

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Becotatug Vedotin, Sintilimab and Cisplatin in people with Nasopharyngeal Carcinoma (NPC), run by First Affiliated Hospital of Guangxi Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 16 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Min Kang, MD (+86-771-5356509, kangmin@gxmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Event-free survival (EFS) (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2026.
