Summary

Head and neck squamous cell carcinoma (HNSCC) is often diagnosed at a locally advanced stage, where cisplatin-based chemoradiotherapy is standard but still results in high recurrence rates. Immunotherapy is promising for HNSCC due to its high mutational burden, and adding PD-1 inhibitors to induction chemotherapy has improved responses without added toxicity. Radiotherapy can further stimulate antitumor immunity.

Iparomlimab and Tuvonralimab, a dual anti-PD-1/CTLA-4 antibody, has shown strong activity across several solid tumors, and early studies suggest synergy with hypofractionated radiotherapy. However, evidence in locally advanced HNSCC is lacking.

The investigators therefore propose a multicenter, single-arm phase II trial to assess the efficacy and safety of combining Iparomlimab and Tuvonralimab injection with chemoradiotherapy in locoregionally advanced HNSCC.

Conditions

Interventions

RADIATION

Hypofractionated Radiotherapy

hypofractionated radiotherapy (5 Gy × 3) for two cycles

DRUG

Chemotherapy

sequential concurrent chemoradiotherapy (50 Gy/25 fractions with two cycles of cisplatin)

DRUG

Iparomlimab and Tuvonralimab injection

Induction therapy include Iparomlimab and Tuvonralimab injection combined with hypofractionated radiotherapy (5 Gy × 3) for two cycles, followed by sequential concurrent chemoradiotherapy (50 Gy/25 fractions with two cycles of cisplatin). After completing chemoradiotherapy, patients receive maintenance Iparomlimab and Tuvonralimab injection for at least six months.
