What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 50 participants in total. It began in 2024-09-03 with a primary completion date of 2026-03-01.

Brief Summary

This study is an exploratory clinical trial to investigate the feasibility of neoadjuvant chemoimmunotherapy plus extrafascial hysterectomy and pelvic lymph node dissection in patients with stage IB2 (2018 FIGO) cervical cancer and to observe the response rate to treatment, adverse effects and complications, and to assess the survival rate of patients.
