GAPP Induction and Concurrent Chemoradiotherapy for High-risk Locoregionally Advanced NPC.

Starting soon · Phase 3

Conditions studied: Nasopharyngeal Carcinoma

In brief

The investigators have designed a multicenter, open-label, randomized controlled phase III clinical study of GAPP induction therapy followed by concurrent chemoradiotherapy and toripalimab maintenance therapy for high-risk locoregionally advanced nasopharyngeal carcinoma (stage III, AJCC 9th edition). The aim is to obtain high-level, high-quality evidence-based data to clarify the efficacy and safety of combining chemoradiotherapy with PD-1 antibody and anlotinib, thereby providing a new treatment strategy to improve the prognosis of patients with high-risk locoregionally advanced nasopharyngeal carcinoma. In this study, GPP induction chemotherapy followed by concurrent chemoradiotherapy and toripalimab maintenance therapy is selected as the control group. This regimen is currently the standard treatment recommended by guidelines for high-risk locoregionally advanced nasopharyngeal carcinoma, with well-established efficacy and broad clinical application. It provides a reliable benchmark for comparing the efficacy and safety of the experimental group, meets ethical requirements, and has mature clinical operational procedures.

You may not qualify if…

• Patients with recurrent or distant metastatic nasopharyngeal carcinoma.
• Pathologically confirmed keratinizing squamous cell carcinoma (WHO type I).
• Receipt of systemic or topical glucocorticoid therapy within 4 weeks prior to enrollment.
• Participation in another clinical trial of an investigational drug within 3 months prior to treatment.
• Known history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation.
• Patients with idiopathic pulmonary fibrosis, drug-induced pneumonitis, organizing pneumonia (i.e., bronchiolitis obliterans), radiation pneumonitis that is clinically symptomatic or requires steroid therapy, active pneumonitis, or other moderate-to-severe pulmonary diseases that significantly affect lung function.
• Comorbidities requiring long-term immunosuppressive medication or systemic/topical corticosteroids at immunosuppressive doses.
• Prior use of anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-CTLA-4 antibodies (or any other antibodies targeting T-cell co-stimulatory or checkpoint pathways) with documented disease progression at the time of study entry.
