Study Overview
Brief Summary
To evaluate the efficacy of neoadjuvant anti-PD-1 plus anti-VEGFR therapy for patients with locally advanced and resectable oral squamous cell carcinoma, and the CPS>10 in the biopsy samples.
Detailed Description
In the previous "Icemelting" trial, neoadjuvant anti-PD-1 plus anti-VEGFR therapy was used in 20 patients with locally advanced and resectable oral squamous cell carcinoma (OSCC), and the neoadjuvant therapy was well-tolerated, with no grade 3-4 toxicity. The MPR rate was 40% (8/20), including 5% (1/20) pathological complete response; furthermore, in the patients with CPS>10, the MPR rate was 100%. As we know, the MPR might transfer to survival benefit in the patients received neoadjuvant therapy. Therefore, in this randomized phase II trial, we aimed to evaluate the survival benefit of neoadjuvant anti-PD-1 plus anti-VEGFR therapy in the patients with locally advanced OSCC and CPS>10 (Icemelting-2 trial). A total of 46 patients will be enrolled in this trial, and the primary endpoint is 2-year disease-free survival rate. The neoadjuvant therapy arm will receive three cycles of Carrelizumab plus Apatinib with 14 days each, followed by the standard treatment of surgery and postoperative adjuvant therapy. The control arm will received the standard treatment of surgery and postoperative adjuvant therapy.

Arms & Interventions
Neoadjuvant arm
The patients received three cycles of neoadjuvant therapy, with 14 days each. Dosage and administration: 200mg Carrelizumab intravenously on the first day of each cycle; Apatinib orally 250mg once a day from the first day of each cycle until the 9th day of the third cycle. Then the patients received the standard treatment of surgery and postoperative adjuvant therapy of radiotherapy or chemoradiotherapy.
Intervention: Camrelizumab (anti-PD-1 inhibitor) (Drug)
Neoadjuvant arm
The patients received three cycles of neoadjuvant therapy, with 14 days each. Dosage and administration: 200mg Carrelizumab intravenously on the first day of each cycle; Apatinib orally 250mg once a day from the first day of each cycle until the 9th day of the third cycle. Then the patients received the standard treatment of surgery and postoperative adjuvant therapy of radiotherapy or chemoradiotherapy.
Intervention: Apatinib (anti-VEGFR inhibitor) (Drug)
Outcomes
Primary Outcomes
2-year disease-free survival rate
Time Frame: 24 months
Disease-free survival was calculated from the date of randomization to tumor recurrence or death from any cause.
Secondary Outcomes
- 2-year overall survival rate(24 months)
- Major pathological response(3 months)
