A Prospective, Single-arm, Phase II Study of Envafolimab Combined With Chemoradiotherapy and Recombinant Human Endostatin in Locally Advanced Nasopharyngeal Carcinoma.

PHASE2 · Chongqing University Cancer Hospital · NCT06059261

This study is testing if adding a new drug called envafolimab to standard chemotherapy and radiation can help people with advanced nasopharyngeal cancer do better in their treatment.

What this trial studies

This multicenter, prospective, single-arm phase II clinical study aims to evaluate the efficacy and safety of envafolimab in combination with chemoradiotherapy and recombinant human endostatin for patients with high-risk locally advanced nasopharyngeal carcinoma. Eligible patients will receive three cycles of induction therapy followed by cisplatin-concomitant radiotherapy and eight cycles of adjuvant therapy with envafolimab. The study focuses on patients with specific staging criteria and requires various pre-treatment assessments, including tumor tissue collection for testing. The goal is to improve treatment outcomes for this challenging cancer type.

Who should consider this trial

Good fit: Ideal candidates are treatment-naive patients aged 18-65 with high-risk locally advanced nasopharyngeal carcinoma.

Not a fit: Patients with early-stage nasopharyngeal carcinoma or those who have received prior treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance treatment efficacy and safety for patients with advanced nasopharyngeal carcinoma.

How similar studies have performed: While similar approaches have been explored, this specific combination of therapies in this patient population is novel and has not been extensively tested.
