What to Expect as a Participant

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

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 30 participants in total. It began in 2023-01-16 with a primary completion date of 2025-12-31.

Brief Summary

This is an investigator-initiated trial aimed at evaluating the safety and preliminary efficacy of a novel red blood cell-based therapy, where engineered red blood cells are conjugated with checkpoint inhibitors.
