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 40 participants in total. It began in 2024-06-20 with a primary completion date of 2025-12.

Had other malignancies within 5 years prior to admission, except basal cell or squamous cell carcinoma of the skin after radical surgery, or carcinoma in situ of the cervix; 4. Receive live vaccine within 4 weeks prior to enrollment or possibly during the study period; 5. Had active autoimmune disease or history of autoimmune disease within 4 weeks prior to enrollment; 6.

Women who are pregnant (positive pregnancy test before medication) or breastfeeding; 17. Two consecutive routine urine tests indicated urine protein ≥2+, and the urine protein volume \>1.0g within 24 hours of reexamination; 18. Patients with ascites or pleural effusion with clinical symptoms; 19.
