Combining Serplulimab with Chemoradiotherapy for High-Risk Postoperative Cervical Cancer

Serplulimab Plus Chemoradiotherapy vs Chemoradiotherapy as Adjuvant Treatment for Postoperative Cervical Cancer Patients With Multiple Risk Factors: A Randomized, Open-Label, Phase II Clinical Trial

Phase 2 Interventional Tianjin Medical University Cancer Institute and Hospital · NCT06727617

This study is testing if adding the immunotherapy drug Serplulimab to standard chemoradiotherapy can help women with high-risk cervical cancer feel better after surgery.

What this trial studies

This Phase II clinical trial investigates the effectiveness and safety of Serplulimab, an immunotherapy drug, when combined with chemoradiotherapy as an adjuvant treatment for women with postoperative cervical cancer who have multiple risk factors. The study will enroll female patients aged 18 to 65 who have undergone radical surgery and have at least two adverse pathological factors. Participants will be randomly assigned to receive either the combination treatment or chemoradiotherapy alone. The trial aims to determine if the addition of Serplulimab improves patient outcomes compared to standard treatment.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 65 with cervical cancer who have undergone radical surgery and exhibit at least two risk factors.

Not a fit: Patients with early-stage cervical cancer or those without the specified risk factors may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates and outcomes for patients with high-risk cervical cancer.

How similar studies have performed: While similar approaches combining immunotherapy with chemoradiotherapy have shown promise in other cancers, this specific combination for cervical cancer is still being evaluated.
