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 260 participants in total. It began in 2024-05-23 with a primary completion date of 2028-05-23.

Brief Summary

This is an open-label, phase I/II study to evaluate the safety, tolerability, pharmacokinetics and immunogenicity of GQ1010 and preliminary anti-tumor efficacy in advanced malignant solid tumor subjects
