Combining tislelizumab with chemoradiotherapy for advanced cervical cancer treatment

Efficacy and Safety of Tislelizumab Combined With Concurrent Chemoradiotherapy as First-line Treatment for Stage IIIC2 Cervical Cancer

Phase 2 Interventional First Affiliated Hospital of Guangxi Medical University · NCT05511623

This study is testing if adding a new immune treatment called tislelizumab to standard chemotherapy and radiation can help people with advanced cervical cancer do better than just the usual treatment.

What this trial studies

This clinical trial evaluates the efficacy and safety of tislelizumab, an immune checkpoint inhibitor, when combined with standard chemoradiotherapy in patients with stage IIIC2 cervical cancer. It is a multicenter, prospective, and randomized phase II trial where participants are assigned to either receive the experimental treatment or standard care. The experimental group will receive concurrent chemoradiotherapy with cisplatin and tislelizumab, while the control group will receive only chemoradiotherapy with cisplatin. The study aims to compare the effectiveness and toxicity of these two treatment regimens.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-70 with histologically confirmed stage IIIC2 cervical cancer and no metastatic disease.

Not a fit: Patients with metastatic cervical cancer or those who do not meet the eligibility criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with advanced cervical cancer by enhancing the effectiveness of standard therapies.

How similar studies have performed: Other studies have shown promising results with similar combinations of immunotherapy and chemoradiotherapy, suggesting potential for success in this approach.
