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 22 participants in total. It began in 2026-05-13 with a primary completion date of 2027-12.

Brief Summary

This study is an open-label, multicenter, dose-escalation and expansion, non-randomized Phase I clinical study to evaluate the safety, tolerability, pharmacokinetic characteristics, and preliminary efficacy of BL-ARC002 for injection in patients with locally advanced or metastatic solid tumors.
