Induction chemotherapy with low-dose radiation and cadonilimab for locally advanced nasopharyngeal carcinoma

Official title: Induction Chemotherapy Combined With Low-dose Radiation Plus Cadonilimab in Loco-regionally Advanced Nasopharyngeal Carcinoma: a Multi-center, Open-label, Randomized Controlled Phase III Clinical Trial

Run by Sun Yat-sen University · NCT05941741 · Data updated 2026-11-12

This study will try adding low-dose radiation and the immune drug cadonilimab to induction chemotherapy before standard concurrent chemoradiotherapy in adults with newly diagnosed locally advanced nasopharyngeal carcinoma.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–70 with newly diagnosed, non-keratinizing (WHO II/III) loco-regionally advanced nasopharyngeal carcinoma (specified T/N stages), ECOG 0–1, adequate organ function, and no prior anti-cancer therapy.

Probably not a fit

Patients with distant metastases, keratinizing histology or other active malignancies, poor organ function, contraindications to chemo/radiation/immunotherapy, or ECOG performance status >1 are unlikely to benefit from this protocol.

What this trial studies

This is a multicenter, open-label, randomized phase III trial comparing induction chemotherapy combined with low-dose radiation and cadonilimab followed by concurrent chemoradiotherapy versus induction chemotherapy followed by standard concurrent chemoradiotherapy. Eligible patients are adults 18–70 years with newly diagnosed non-keratinizing loco-regionally advanced nasopharyngeal carcinoma (T4N1M0 or T1-4N2-3M0) and ECOG 0–1. Interventions include intensity-modulated radiation therapy, standard chemotherapy, low-dose radiotherapy during induction, and the immune checkpoint inhibitor cadonilimab, with participants randomized to the experimental or control arm. Primary outcomes compare treatment efficacy, treatment-related adverse events, and patient-reported quality of life between the two groups with planned follow-up for survival and toxicity.

Why it matters

Potential benefit: If successful, the approach could improve local control and survival while maintaining acceptable toxicity and quality of life for patients with locally advanced nasopharyngeal carcinoma.

How similar studies have gone: Previous phase II/III studies adding PD-1 immune checkpoint inhibitors to chemotherapy and radiotherapy in nasopharyngeal carcinoma have shown improved outcomes, but combining low-dose radiation with cadonilimab is a newer strategy with limited prior data.
