Brief summary
This trial aims to study the role of Ivonescimab combined with chemoradiotherapy in high-Risk locoregionally advanced nasopharyngeal carcinoma.
Detailed description
The trial plans to enroll patients with T3N2M0+ Stage III (AJCC 9th) locoregionally advanced nasopharyngeal carcinoma (LANPC). Patients will receive 3 cycles of induction chemotherapy with gemcitabine and cisplatin combined with ivonescimab, followed by concurrent chemoradiotherapy with cisplatin, and then 9 cycles of adjuvant ivonescimab. Ivonescimab will be administered every 3 weeks starting from day 1 of induction therapy and continued through the adjuvant phase.
Interventions
Ivonescimab (AK112) is a novel PD-1/VEGF bispecific antibody designed to simultaneously block PD-1-mediated immune evasion and inhibit VEGF-driven angiogenesis. In this study, ivonescimab is administered intravenously at a dose of 10 mg/kg every 3 weeks, starting on Day 1 of induction chemotherapy (3 cycles), followed by concurrent chemoradiotherapy (no ivonescimab), and then continued as adjuvant monotherapy for 9 additional cycles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Complete response rate (CRR) | At the end of induction therapy | Disappearance of all target lesions, with all pathological lymph nodes (including both target and non-target nodes) reduced in short axis to less than 10 mm. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Failure-free survival (FFS) | 2 years | calculated from enrolment to the date of locoregional recurrence, distant metastasis, or death from any cause, whichever occurred first. |
| Overall survival (OS) | 2 years | calculated from enrolment to the date of death from any cause. |
| Distant metastasis-free survival (DMFS) | 2 years | calculated from enrolment to the date of first distant metastasis. |
| Objective response rate (ORR) | At the end of induction therapy | Objective Response Rate (ORR) is defined as the proportion of patients who achieve either a Complete Response (CR) or a Partial Response (PR) as assessed per RECIST v1.1 criteria. |
| Adverse events (AEs) and serious adverse events (SAEs) | 2 years | Analysis of adverse events (AEs) are based on treatmentrelated AEs (trAEs) and immune-related AEs (irAEs), and all-grade AEs and grade 3-4 AEs. Graded according to CTCAE V5.0. |
| Quality of life (QoL) | 2 years | Change in quality of life (QoL) will be assessed at six time points: prior to enrollment (baseline), after completion of induction immunotherapy, after completion of concurrent chemoradiotherapy, after the 5th cycle of adjuvant immunotherapy, after completion of all adjuvant immunotherapy, and at 6 months following the end of adjuvant immunotherapy. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), version 3.0, will be used. This validated instrument contains 30 items, of which 24 are grouped into nine multi-item scales: five functional scales, three symptom scales, and one global health status/QoL scale. The remaining six items are single-item symptom scales. All 15 scales will be scored according to the EORTC QLQ-C30 Scoring Manual.Each scale is linearly transformed to a 0-100 scale. Higher scores indicate better functioning and QoL on functional and global health scales, but worse symptoms on symptom scales. |
| Locoregional recurrence-free survival (LRRFS) | 2 years | calculated from enrolment to the date of locoregional persistence or 1st locoregional recurrence. |
