Brief summary
At present, the treatment regimen of locally advanced nasopharyngeal carcinoma still needs to be further improved, and the focus of improvement lies in replacing cisplatin with high-efficiency and low-toxicity treatment regimen. Considering the synergistic effect among radiotherapy, immunotherapy and anti-angiogenesis therapy, we chose PD-1 inhibitor combined with bevacizumab to replace cisplatin chemotherapy.
Detailed description
We plan to use PD-1 inhibitor combined with bevacizumab to replace cisplatin (induction + concurrent ± adjuvant) in patients with locally advanced nasopharyngeal carcinoma. Considering the safety of the original study, we will set up two groups for the adjuvant treatment stage: one group will only use PD-1 inhibitor at the adjuvant treatment stage (low risk group), and the other group will use bevacizumab +PD-1 inhibitor combined treatment (high risk group). Once the efficacy and safety of this protocol are confirmed, it may provide a new treatment option for locally advanced nasopharyngeal carcinoma.
Interventions
DRUGBevacizumab+Toripalimab+gemcitabine, adjuvant with Bevacizumab and Toripalimab
Induction therapy: Toripalimab (240mg iv drip)+Bevacizumab (7.5mg/kg iv drip)+gemcitabine (1,000 mg/m2), every 3 weeks for 3 cycles before radiotherapy. Concurrent therapy: Toripalimab (240mg iv drip)+Bevacizumab (7.5mg/kg iv drip), every 3 weeks for 2 cycles during radiotherapy. Adjuvant therapy: Toripalimab (240mg iv drip)+Bevacizumab (7.5mg/kg iv drip), every 3 weeks for 1 year after radiotherapy. Radiation: Intensity-modulated radiotherapy.

Primary
| Measure | Time frame | Description |
|---|---|---|
| grade ≥3 nasopharyngeal necrosis or hemorrhage | At the end of each cycle (each cycle is 21 days) | Incidence of nasopharyngeal necrosis or massive hemorrhage (grade ≥3). Grade ≥3 hemorrhage: Grade 3, Transfusion indicated; invasive intervention indicated; hospitalization. Grade 4, Life-threatening consequences; urgent intervention indicated (e.g., tracheotomy or intubation). Grade 5, death. Grade ≥3 nasopharyngeal necrosis: Grade 3, Severe pain; unable to adequately aliment or hydrate orally; limiting self care ADL. Grade 4, Life-threatening consequences; urgent intervention indicated. Grade 5, death. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | 3 year | Progress-free survival is calculated from the date of enrollment to the date of the first progression at any site or death from any cause or censored at the date of the last follow-up. |
| Overall survival | 3 year | Overall survival is calculated from the date of enrollment to the date of the death from any cause or censored at the date of the last follow-up. |
| Objective response rate | 3 weeks after indution therapy; 3 months after concurrent therapy | The proportion of patients whose tumors shrink to a certain size and maintain such size for a certain period of time, including patients with complete response (CR) and partial response (PR). |
| Distant metastasis-free survival (DMFS) | 3 year | Defined as the time from registration to distant metastasis, or death from any cause. |
| Incidence rate of adverse events (AEs) | 3 year | Analysis of acute and late adverse events (AEs) are evaluated. Numbers of patients of treatment-related adverse events (acute toxicity) and late radiation toxicities were assessed by CTCAE v5.0. |
| Locoregional failure-free survival (LRRFS) | 3 year | Defined as the time from registration to local or regional relapse, or death from any cause. |
