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 57 participants in total. It began in 2024-11-20 with a primary completion date of 2026-11-30.

Brief Summary

The main purpose of this trial is to investigate and evaluate the efficacy of cryoablation combined with camrelizumab treatment to patients with advanced or inoperable soft tissue sarcomas after standard treatment failure.
