Clinical Trial Summary

To evaluate the safety and efficacy of combination of Sintilimab and SBRT on the basis of platinum-containing chemotherapy as the first-line treatment of limited metastatic head and neck squamous cell carcinoma (LM-HNSCC).

Description:

For patients with LM-HNSCC, the conventional first-line treatment is EXTREME regimen dominated systemic therapy. In the recent era, immunotherapy has emerged to be the paramount issue for cancer treatment. A series of high-quality clinical studies demonstrated that immunotherapy (such as PD1 inhibitor) with or without chemotherapy (depending on CPS status) offered significant survival benefits to patients with recurrent or metastatic (R/M) HNSCC and the toxicities were well tolerated, whereas the PFS was still dismal. SBRT is associated with initiating release of tumor antigens, promoting DC activation, activating APCs, priming CD8+ CTLs, leading to the potential of abscopal effect. Therefore, we hypothesized that adding SBRT to Sintilimab (a PD1 inhibitor) and platinum-containing chemotherapy as the first-line treatment may improve the PFS for limited metastatic head and neck squamous cell carcinoma (LM-HNSCC).

Alternative therapies (such as thyroxine, insulin, or physiological glucocorticoids for adrenal or pituitary insufficiency, etc.) are not considered systemic treatments;
• Administration of systemic steroid (not include nasal spray, inhalation or other local approach) within 7 days before the first administration of Sintilimab or any other ways of immunosuppression;
• Receiving Xenografts or allogeneic hematopoietic stem cell transplantation in the past;
• Allergic to component of research drugs or adjacent;
• HIV infection;
• Untreated active hepatitis B (HBsAg positive and HBV-DNA copy number larger than upper limit of threshold);

Intervention

Drug:
• Sintilimab
Sintilimab: 200mg, administered by intravenous infusion on the first day of each cycle, one cycle every 3 weeks (Q3W), with the maximum cycle of 17. Suspension of Sintilimab administration: patients's request, disease progression, researcher-evaluated SAE

Radiation:
• SBRT
At least one metastatic lesion is suitable for SBRT. If applicable, all metastatic lesions were allowed to be irradiated. Recommended dose: BED = 80Gy. Dose fractionation is determined as per physician's discretion, generally depending on the location of irradiated lesion and the distance to surrounding OARs. Timing of SBRT: After completing at least 2 platinum-containing chemotherapy plus sintilimab treatments, SBRT can be started after assessing that there is no AE = G2.

Drug:
• Platinum based chemotherapy
Platinum based single or doublet chemotherapy, one cycle every 3 weeks (Q3W), 4-6 cycles.
