Summary

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.

Conditions

  • Nasopharyngeal Cancinoma (NPC)

Interventions

DRUG

Becotatug vedotin

Becotatug vedotin during concurrent radiotherapy and the adjuvant phase

DRUG

Becotatug vedotin

1. Induction Chemotherapy (TPP Regimen) Docetaxel 75 mg/m² d1 + Cisplatin (DDP) 75 mg/m² d1 + PD-1 inhibitor , administered every 3 weeks for a total of 3 cycles. 2. Concurrent Radiotherapy (Becotatug vedotin + IMRT) Concurrent radiotherapy commences 3 weeks after the completion of induction chemotherapy: Becotatug vedotin 2.3 mg/kg d1, starting on the first day of radiotherapy, administered every 3 weeks during the radiotherapy period for a total of 3 cycles. The radiotherapy technique employed is intensity-modulated radiotherapy (IMRT). 3. Adjuvant Therapy Adjuvant therapy commences 4-6 weeks after the completion of radiotherapy: Becotatug vedotin 2.3 mg/kg d1, administered every 3 weeks for a total of 3 cycles.
