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 49 participants in total. It began in 2023-12-20 with a primary completion date of 2026-06-30.

Brief Summary

To assess the safety and tolerability, obtain the recommended phase 2 dose (RP2D)/optimal biologic dose (OBD) and/or Maximum Tolerated Dose (MTD) for LM-24C5 in subjects with advanced solid tumors.
